Efficiently conduct clinical development to establish clinical proof of concept with our lead product candidates. Levosimendan and Oxycyte representrepresents novel therapeutic modalities for the treatment of LCOS, TBIpulmonary hypertension and other critical care conditions. We are conducting clinical development in a variety of clinical studies with the intent to establish proof of concept in a number ofseveral important disease areas where these therapeutics would be expected to have benefit. Our focus is on conducting well-designed studies early in the clinical development process to establish a robust foundation for subsequent development, partnership and expansion into complementary areas.

 
Efficiently explore new high potential therapeutic applications, leveraging third-party research collaborations and our results from related areas. Our product candidates have shown promise in multiple disease areas. We are committed to exploring potential clinical indications where our therapies may achieve best-in-class profile, and where we can address significant unmet medical needs. In order to achieve this goal, we have established collaborative research relationships with investigators from research and clinical institutions and the United States Army and Navy.our strategic partners. These collaborative relationships have enabled us to cost effectively explore where our product candidates may have therapeutic relevance, and how it may be utilized to advance treatment over current clinical care. Additionally, we believe we will be able to leverage clinical safety data and preclinical results from some programs to support accelerated clinical development efforts in other areas, saving substantial development time and resources compared to traditional drug development.
 
Continue to expand our intellectual property portfolio. Our intellectual property is important to our business and we take significant steps to protect its value.

In addition to our internal development efforts, an important part of our product development strategy is to work with collaborators and partners to accelerate product development, reduce our development costs, and broaden our commercialization capabilities. We believe that this strategy will help us to develop a portfolio of high quality product development opportunities, enhance our clinical development and commercialization capabilities, and increase our ability to generate value from our proprietary technologies.
 
Our Current Programs
 
Levosimendan Background
 
Levosimendan was discovered and developed by Orion Pharma,Corporation, a Finnish company.company, or Orion. Levosimendan is a calcium sensitizersensitizer/K-ATP activator developed for intravenous use in hospitalized patients with acutely decompensated heart failure. It is currently approved in over 5060 countries for this indication and not available in the United States or Canada. It is estimated that to date over 1,000,000 patients have been treated worldwide with levosimendan.
Levosimendan is a novel, first in class calcium sensitizer/K-ATP activator. The therapeutic effects of levosimendan are mediated through:
● 
Increased cardiac contractility by calcium sensitization of troponin C, resulting in a positive inotropic effect which is not associated with substantial increases in oxygen demand.
● 
Opening of potassium channels in the vasculature smooth muscle, resulting in a vasodilatory effect on all vascular beds.
● 
Opening of mitochondrial potassium channels in cardiomyocytes, resulting in a cardioprotective effect.
This triple mechanism of action helps to preserve heart function during cardiac surgery. Several studies have demonstrated that levosimendan protects the heart and improves tissue perfusion while minimizing tissue damage during cardiac surgery.
In 2013, we acquired certain assets of Phyxius Pharma, Inc., or Phyxius, including its North American rights to develop and commercialize levosimendan for any indication in the United States and Canada. In the countries where levosimendan is marketed, Levosimendan is indicated for the short-term treatment of acutely decompensated severe chronic heart failure in situations where conventional therapy is not sufficient, and in cases where inotropic support is considered appropriate. In acute decompensated heart failure patients, levosimendan has been shown to significantly improve patients’ symptoms as well as acute hemodynamic measurements such as increased cardiac output, reduced preload and reduced afterload.  Other unique properties of levosimendan include sustained efficacy through the formation of a long acting metabolite, lack of impairment of diastolic function, and evidence of better compatibility with beta blockers than dobutamine.

The European Society of Cardiology, or the ESC, recommends levosimendan as a preferable agent over dobutamine to reverse the effect of beta blockade if it is thought to be contributing to hypotension. The ESC guidelines also state that levosimendan is not appropriate for patients with systolic blood pressure less than 85mmHg or in patients in cardiogenic shock unless it is used in combination with other inotropes or vasopressors.
Levosimendan Development for Pulmonary Hypertension Patients
Levosimendan is under development in North America for reductionthe treatment of patients with pulmonary hypertension associated with heart failure with preserved ejection fraction, or PH-HFpEF.  PH-HFpEF is defined hemodynamically by a pulmonary artery pressure, or mPAP, ≥25 mmHg, a pulmonary capillary wedge pressure, or PCWP, >15 mmHg, and a diastolic pressure gradient, or diastolic PAP – PCWP, >7mmHg. Pulmonary hypertension in these patients initially develops from a passive backward transmission of elevated filling pressures from left-sided heart failure. These mechanical components of pulmonary venous congestion may trigger pulmonary vasoconstriction, decreased nitric oxide availability, increased endothelin expression, desensitization to natriuretic peptide induced vasodilation, and vascular remodeling.  Finally, these changes often lead to advanced pulmonary vascular disease, increased right ventricle, or RV, afterload, and RV failure.
PH-HFpEF is a common form of pulmonary hypertension with an estimated US prevalence exceeding 1.5 million patients. Currently, no pharmacologic therapies are approved for treatment of PH-HFpEF.  Despite the fact that many therapies have been studied in PH-HFpEF patients, including therapies approved to treat pulmonary arterial hypertension patients, no therapies have been shown to be effective in treating PH-HFpEF patients.
Published pre-clinical and clinical studies indicate that levosimendan may provide important benefits to patients with pulmonary hypertension. Data from these published trials indicate that levosimendan may reduce pulmonary vascular resistance and improve important cardiovascular hemodynamics such as reduced pulmonary capillary wedge pressure in patients with pulmonary hypertension. In addition, several published studies provide evidence that levosimendan may improve right ventricular dysfunction which is a common comorbidity in patients with pulmonary hypertension. While none of these studies have focused specifically on PH-HFpEF patients, the general hemodynamic improvements in these published studies of various types of pulmonary hypertension provide an indication that levosimendan may be beneficial in PH-HFpEF patients.
We plan to meet with the United States Food and Drug Administration, or FDA, to discuss the design of a proposed Phase 2 trial in PH-HFpEF patients during the first half of 2018. Following feedback from that meeting, we plan to complete the design of the Phase 2 trial and begin enrollment of the trial in the second half of 2018. 
Levosimendan Development for Cardiac Surgery Patients
Low cardiac output syndrome, or LCOS, is generally defined as a patient’s inability to maintain a cardiac index >2.2 L/min/m2 and hence requiring use of inotropic agents and/or mechanical assist devices such as an intra-aortic balloon pump or a left ventricular assistance device. LCOS in the cardiac surgery setting is reported to occur in 5-10% of patients undergoing cardiac surgery and is associated with 10-15 fold higher mortality or severe sequelae as a result of poor organ perfusion.
Currently, no pharmacologic therapies are approved for management or prevention of post-cardiotomy LCOS. While conventional inotropes are used to manage cardiac hemodynamics in the peri-operative setting, none have been shown to improve outcomes.
Substantial published scientific research indicates that levosimendan may provide important benefits to cardiac surgery patients, including 35 published prospectively designed clinical trials and multiple published meta-analyses. Many of these publications indicate that levosimendan provides substantial mortality and or morbidity benefits to cardiac surgery patients, particularly those at risk of developing LCOS.
In 2014, we initiated a Phase 3 trial (LEVO-CTS) to investigate the safety and efficacy of pre-operative administration of levosimendan treatment to reduce the mortality and morbidity in cardiac surgery patients at risk for developing LCOS. The Phase 3 trial was conducted under an FDA approved Special Protocol Assessment, or SPA, and with FDA granted Fast Track status for the development of levosimendan to reduce mortality and morbidity in cardiac surgery patients at risk of LCOS. Our acquisition of levosimendan brings to Oxygen Biotherapeutics not only the exclusive rights in the United States and Canada to develop and commercialize levosimendan for the specific indication of prevention and treatment of LCOS, but also the United States Food and Drug Administration’s, or FDA’s, approval of Fast Track status for a Phase 3 trial, and the FDA’s Special Protocol Assessment or SPA which represents agreement with the Phase III clinical trial’s study protocol. The FDA has also provided guidance that a single successful trial will be sufficient to support approval of levosimendan in this indication. Pursuant to our license to levosimendan, we are required to use the “Simdax®“Simdax®” trademark to commercialize this product.

 
The effectsLEVO-CTS trial design was guided by the published literature, including important dosing refinements and inclusion of patients with low preoperative ejection fraction. In addition, we relied heavily on the input of European clinicians who have significant personal clinical experience with the use of levosimendan are mediated through:
-  increased cardiac contractility by calcium sensitization of troponin C;
-  vasodilation through the opening of potassium channels; and
-  cardioprotection and antiapoptopic effect through the opening of mitochondrial potassium channel.
The physiologic effects of levosimendan have been very well characterized in clinical trials of acutely decompensated heart failure or ADHF patients andtreating cardiac surgery patients. The collective findings of these clinical trials form the basis for developing levosimendan in cardiac surgery patients at risk for LCOS.
 
Current data in cardiac surgery suggest that levosimendan is superior to traditional inotropes (dobutamine, phosphodiesterase [PDE]-inhibitors) as it achieves:
 
-  sustained hemodynamic improvement;
● 
sustained hemodynamic improvement;
●

We have selected Duke University’s Duke Clinical Research Institute, or DCRI, to conduct the Phase 3 trial of levosimendan. DCRI is the world’s largest academic clinical research organization, with substantial experience in conducting cardiac surgery trials. The Phase 3 trial will bewas conducted in approximately 5060 major cardiac surgery centers in North America. The trial will enrollenrolled patients undergoing coronary artery bypass graphsgrafts, or CABG, and/or mitral valve surgery, and CABG with aortic valve surgery who are at risk for developing LCOS. The trial is expected to bewas designed as a double blind, randomized, placebo controlledplacebo-controlled study seeking to enroll 760 patients. It is expected thatDuring 2016 we made the decision to increase enrollment will beginin the LEVO-CTS trial to 880 patients. These additional patients were necessary to ensure sufficient powering and were necessary due to:
● 
a small percentage of patients who were randomized but did not receive the study drug;
● 
a small percentage of patients who were missing one or more component measurements of the primary endpoint; and
● 
a slightly lower primary endpoint event rate than we originally projected.
Enrollment began in the third quarter of calendar year 2014 and will take approximately 18 months to complete. The protocolwas completed in December of 2016. On January 31, 2017, we announced top-line results from the Phase 3 trial has been submittedLEVO-CTS trial. Levosimendan, given prophylactically prior to ClinicalTrials.gov.cardiac surgery to patients with reduced left ventricular function, had no effect on the co-primary outcomes. The study did not achieve statistically significant reductions in the dual endpoint of death or use of a mechanical assist device at 30 days, nor in the quad endpoint of death, myocardial infarction, need for dialysis, or use of a mechanical assist device at 30 days.
 
ShouldHowever, the study results demonstrated statistically significant reductions in two of three secondary endpoints including reduction in LCOS and a reduction in postoperative use of secondary inotropes. Additionally, levosimendan successfully progresswas found to be safe with no clinically significant increases in hypotension or cardiac arrhythmias and the clinical testing and if it appears regulatory approval for one or more medical uses is likely, we intend to evaluate our options for commercializingdata showed a non-significant numerical reduction in 90-day mortality.
A post hoc analysis on patients in whom isolated CABG surgery was performed (66% of the product. These options include licensingpatients) revealed that levosimendan to a third party for distribution, selling the product ourselves, or establishing some other form of strategic relationship for making and distributing levosimendanimproved 90-day survival significantly (p=0.0017). This was accompanied with a participantsignificant improvement in postoperative cardiac index, in the pharmaceutical industry. We are currently investigatingfrequency of LCOS and evaluating all options.
Oxycytein the need for further inotropic support. Accordingly, the reductions in the incidence of LCOS were associated with a substantial improvement in mortality. However, there was essentially no effect on any of these endpoints in those LEVO-CTS patients receiving valve surgeries.
 
Our Oxycyte oxygen carrier product is a PFC-based oil in water emulsion, which is provided to the patient intravenously. The physical-chemical properties of PFCs enable our product to concentrate oxygen from the lungs and transport it through the body releasing it along the way.  Over a period of days Oxycyte is gradually exhaled through the lungs during the normal process of respiration. Oxycyte requires no cross matching, so it is immediately available and compatible with all patients’ blood types. Oxycyte has an extended shelf life compared to blood and is provided as a sterile emulsion ready for intravenous administration.  Because it contains no biological components, there is reduced risk of transmission of blood-borne viruses from human blood products.  Further, since Oxycyte is based on readily available inert compounds, we believe it can be manufactured on a cost-effective basis in amounts sufficient to meet demand.
We received approval of our Investigational New Drug application, or IND, for severe TBI filed with FDA and began Phase I clinical studies in October 2003, which were completed in December 2003. We submitted a report on the results to the FDA along with a Phase II protocol in 2004. Phase II-A clinical studies began in the fourth quarter of 2004, and were completed in 2006. A further Phase II study protocol was filed with the FDA in the spring of 2008, but remained on clinical hold by the FDA due to safety concerns raised by the regulatory agency.
Despite the FDA’s postponement of Oxycyte trials in the United States, we filed a revised protocol as a dose-escalation study with the regulatory authorities in Switzerland and Israel. The relevant Swiss regulatory body approved the protocol in August 2009, and the Israel Ministry of Health approved the protocol in September 2009. The new study began in October 2009. In March 2010, we determined that it is feasible to simplify the trial design and also reduce the number of patients to be enrolled. We have completed the first of three cohorts and we were authorized by the Swiss and Israeli regulatory authorities to initiate the second cohort.  Despite their authorization, we stopped enrollment in order to reevaluate the protocol’s patient enrollment parameters, secure our Current Good Manufacturing Practice, or cGMP, supply of Oxycyte, review our contractor and clinical sites, and examine the possibility of opening clinical sites in other countries. In July 2013 we resumed enrollment in the second cohort. Upon completion of the Phase II trials, a Phase III trial will need to be implemented.  In that instance, we would seek a partner to either conduct the Phase III trials, or collaborate with us to conduct the trials.
 
In March 2011,the second and third quarters of 2017 we received confirmationexplored the opportunity for submitting a new drug application, or NDA, for use of a $2.07 million, two-year cost reimbursement award fromlevosimendan in CABG surgery patients on the U.S. Army to conduct safety related studies for Oxycyte.  PFC emulsions, as a therapeutic class, are known to interact with the reticuloendothelial system as partbasis of the clearance mechanism, as well as affectrobust reduction in 90-day mortality observed in the number of circulating platelets. The studies supported by this grant will examine the effects of Oxycyte on the immune system, platelet function and distribution, as well as the safety and efficacy of platelet transfusion, which can be necessary for patients with TBI and related polytrauma. Additional studies under this grant will be conducted to evaluate the pharmacokinetics of PFCs in relevant species. On September 12, 2013, we submitted toLEVO-CTS trial. However, the FDA results from two series of animal studies designed to address Agency concerns regarding the use of Oxycyteadvised that another study in treating TBI patients. These studies were conducted to probe both the interactions between Oxycyte and the immune system as well as assess the PFC-based emulsion’s potential to increase the risk of intracerebral hemorrhage (ICH). We expect to complete the remaining studies over the next 12 months.CABG surgery patients would be required that prospectively tests levosimendan’s effectiveness in improving mortality.

On February 28, 2014,Accordingly, we were notified that the FDA had completed its reviewhave suspended development of the September 2013 nonclinical submission and that we satisfactorily addressed all clinical hold issues identified by the agency. In connection with this notice, the FDA lifted the clinical hold on Oxycyte. Lifting of the clinical hold clears uslevosimendan for use in CABG patients due to proceed with the clinical development program in the United States.
Should Oxycyte successfully progress in clinical testing and if it appears regulatory approval for one or more medical uses is likely, either in the United States or in another country, we intend to evaluate our options for commercializing the product. These options include licensing Oxycyte to a third party for manufacture and distribution, manufacturing Oxycyte ourselves for distribution through third party distributors, manufacturing and selling the product ourselves, or establishing some other form of strategic relationship for making and distributing Oxycyte with a participant in the pharmaceutical industry. We are currently investigating and evaluating all options.
We believe that important competitive factors in the market for oxygen carrier products will include the relative speed with which competitors can develop their respective products, complete the clinical testing and regulatory approval process, and supply commercial quantities of their products to the market. In addition to these factors, competition is expected to be based on the effectiveness of oxygen carrier products and the scope of the intended uses for which they are approved, the scope and enforceability of patent or other proprietary rights, product price, product supply, and marketing and sales capability. We believe that our competitive position will be significantly influencedrepeat study, as required by the FDA. The incidence of 90-day mortality in CABG surgery patients is low (~8%). The repeat study would need to randomize approximately 1200 CABG surgery patients with low LVEF (<35%) to demonstrate a >50% risk reduction in mortality. Based on this analysis, we determined the cost and timing of this study would outweigh the clinical testing and regulatory filings for Oxycyte, our ability to maintain and enforce our proprietary rights covering Oxycyte and its manufacturing process, and our ability to develop capabilities for manufacturing and distributing the product ourselves or with others, should we obtain regulatory approval.likely benefit.
 
Other Products
In addition to our primary products described above, we have also developed our Dermacyte® line of topical cosmetic products, which contain our patented PFC technology and other known cosmetic ingredients to promote the appearance of skin health and other desirable cosmetic benefits, as well as Wundecyte™, a novel gel developed under a contract agreement with a lab in Virginia that is designed to be used as a wound-healing gel.  At this time, we do not expect that Dermacyte or Wundecyte constitute a material portion of our business going forward.
Suppliers
 
Pursuant to the terms of our license for levosimendan, Orion Corporation is our sole manufacturing source for levosimendan.
 
With respect to Oxycyte, we are actively pursuing agreements with multiple manufacturers to ensure we are able to consistently obtain our raw materials and topical products timely, within our defined specifications, and at competitive prices.
Our FtBu PFC currently is manufactured by Fluoromed. We have obtained exclusive manufacturing rights for our PFC, and we strengthened these rights with documentation of the manufacturer’s critical formulations and processes. This documentation is being held in escrow and will revert to us in the event the manufacturer undergoes a change-of-control or fails to remain a going concern.
In September 2011 we entered into a development and supply agreement with Bioserve, Inc. to manufacture our Oxycyte emulsion for clinical use under cGMP standards. In January 2012, Bioserve transferred the manufacturing process from Hospira, our previous supplier, to their cGMP facilities and demonstrated their ability to produce clinical grade Oxycyte.
Intellectual Property
 
We rely on a combination of patent applications, patents, trade secrets, proprietary know-how, trademarks, and contractual provisions to protect our proprietary rights. We believe that to have a competitive advantage, we must develop and maintain the proprietary aspects of our technologies. Currently, we require our officers, employees, consultants, contractors, manufacturers, outside scientific collaborators and sponsored researchers, and other advisors to execute confidentiality agreements in connection with their employment, consulting, or advisory relationships with us, where appropriate. We also require our employees, consultants, and advisors who we expect to work on our products to agree to disclose and assign to us all inventions conceived during the work day, developed using our property, or which relate to our business.

Competition
The pharmaceutical and biotechnology industries are intensely competitive. Many companies, including biotechnology, chemical and pharmaceutical companies, are actively engaged in activities similar to ours, including research and development of drugs for the treatment of rare medical conditions. Many of these companies have substantially greater financial and other resources, larger research and development staffs, and more extensive marketing and manufacturing organizations than we do. In addition, some of them have considerable experience in preclinical testing, clinical trials and other regulatory approval procedures. In addition, there are also academic institutions, governmental agencies and other research organizations that are conducting research in areas in which we are working. We expect to encounter significant competition for any of the pharmaceutical products we plan to develop.

We believe the concept of using a medication to treat pulmonary hypertension is novel. Because therapies are commonly used to treat pulmonary hypertension, our ability to succeed in the market is dependent on our ability to change the established practice paradigm, which is never an easy task. Key factors on which we will compete with regards to the development and marketing of levosimendan for the treatment of pulmonary hypertension include, among others, the ability to obtain adequate efficacy data, safety data, cost effectiveness data and hospital formulary approval, as well as sufficient distribution and handling. Furthermore, while we believe the mechanism of action of levosimendan is novel, other low priced generically available products possess some similar qualities, which could present competition in the form of therapeutic substitution.
 
In addition,order to compete successfully in this and other therapeutic areas, we own numerous domain names relevantmust develop proprietary positions in patented drugs for therapeutic markets that have not been satisfactorily addressed by conventional research strategies. Our product candidates, even if successfully tested and developed, may not be adopted by physicians over other products and may not offer economically feasible alternatives to our business, such as www.oxygenbiotherapeutics.com, www.DermacyteUS.com, www.oxybiomed.com, and others.other therapies.
 
Government regulationRegulation
 
The manufacture and distribution of levosimendan and Oxycyte, as well as our other products, and the operation of our manufacturing facilities will require the approval of United States government authorities as well as those of foreign countries. In the United States, the FDA regulates medical products. The Federal Food, Drug and Cosmetic Act and the Public Health Service Act govern the testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of our medical products. In addition to FDA regulations, we are also subject to other federal and state regulations, such as the Occupational Safety and Health Act and the Environmental Protection Act. Product development and approval within this regulatory framework requires a number of years and involves the expenditure of substantial funds.
 
Preclinical tests include evaluation of product chemistry and studies to assess the safety and effectiveness of the product and its formulation. The results of the preclinical tests are submitted to the FDA as part of the application. The goal of clinical testing is the demonstration in adequate and well-controlled studies of substantial evidence of the safety and effectiveness of the product in the setting of its intended use. The results of preclinical and clinical testing are submitted to the FDA from time to time throughout the trial process. In addition, before approval for the commercial sale of a product can be obtained, results of the preclinical and clinical studies must be submitted to the FDA. The testing and approval process requires substantial time and effort and there can be no assurance that any approval will be granted on a timely basis, if at all. The approval process is affected by a number of factors, including the severity of the condition being treated, the availability of alternative treatments and the risks and benefits demonstrated in clinical trials. Additional preclinical studies or clinical trials may be requested during the FDA review process and may delay product approval. After FDA approval for its initial indications, further clinical trials may be necessary to gain approval for the use of a product for additional indications. The FDA may also require post-marketing testing, which can involve significant expense, to monitor for adverse effects.

Our regulatory strategy isAs noted above, following the announcement of the Phase 3 LEVO-CTS top-line results, we held a meeting with the FDA to pursue Phase III clinical testingreview the preliminary trial data and discuss a path forward to file a NDA for levosimendanlevosimendan. We explored the opportunity to submit an NDA for use in CABG patients on the basis of the robust reduction in 90-day mortality observed in the United States. We then intend to use the results of theseLEVO-CTS trial. The FDA advised that another study in CABG surgery patients would be required that prospectively tests to pursue FDA marketing approval of levosimendanlevosimendan’s effectiveness in the United States. In addition, we are continuing with our Phase II clinical testing and initial regulatory approval of Oxycyte in Switzerland and Israel.improving mortality.
 
Research and Development
 
Our research and development efforts will beare focused on the development and commercialization of levosimendan for its use in clinical indications, primarily LCOS. We arepulmonary hypertension. Previously, we were also focusingfocused on furthering the development and manufacture of Oxycytelevosimendan for its use in clinical indications, primarily TBI, spinal cord injury, and decompression sickness. for the treatment of LCOS. However, we have suspended the development of levosimendan for the treatment of LCOS while we evaluate strategic alternatives.
We spent approximately $3.0$3.5 million and $2.5$13.1 million on research and development during each of the fiscal years ended April 30, 2014December 31, 2017 and 2013,2016, respectively.

 
Employees
 
We believe that our success will be based on, among other things, the quality of our clinical programs, our ability to invent and develop superior and innovative technologies and products, and our ability to attract and retain capable management and other personnel. We have assembled a high quality team of scientists, clinical development managers and executives with significant experience in the biotechnology and pharmaceutical industries.
 
As of April 30, 2014,December 31, 2017, we had 14seven full-time employees.employees and one part-time employee. In addition to our employees, we also use the service and support of outside consultants and advisors. None of our employees are represented by a union, and we believe relationships with our employees are good.

ITEM 1A—RISK FACTORS
 
Risks Related to Our Financial Position and Need for Additional Capital
 
We have a limited operating history, and we expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.
 
Our operations, to date, have been primarily limited to organizing and staffing our company, developing our technology and undertaking preclinical studies and clinical trials of our product candidates. We have not yet obtained regulatory approvals for any of our clinical product candidates. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.
 
Specifically, our financial condition and operating results have varied significantly in the past and will continue to fluctuate from quarter-to-quarter and year-to-year in the future due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include the following factors, among others:
 
our ability to obtain additional funding to develop our product candidates;
our ability to obtain additional funding to develop our product candidates;
-  the need to obtain regulatory approval of our most advanced product candidates;
-  potential risks related to any collaborations we may enter into for our product candidates;
-  delays in the commencement, enrollment and completion of clinical testing, as well as the analysis and reporting of results from such clinical testing;
-  the success of clinical trials of our Oxycyte and levosimendan product candidates or future product candidates;
-  any delays in regulatory review and approval of product candidates in development;
the need to obtain regulatory approval of our most advanced product candidates;

potential product liability claims and adverse events;
potential side effects of our product candidates that could delay or prevent commercialization;
potential liabilities associated with hazardous materials;
potential product liability claims and adverse events;
our ability to maintain adequate insurance policies;

our ability to attract and retain key personnel to manage our business effectively.
-  our ability to adequately support future growth; and
-  our ability to attract and retain key personnel to manage our business effectively.
 
Due to the various factors mentioned above, and others, the results of any prior quarterly or annual periods should not be relied upon as indications of our future operating performance.
 
We may need additional funding and if we are unable to raise capital when needed, we would be forced to delay, reduce or eliminate our product development programs.
 
Developing biopharmaceutical products, including conducting preclinical studies and clinical trials and establishing manufacturing capabilities, is expensive. We expect our research and development expenses to increase in connection with our ongoing activities, particularly as we focus on and proceed with our Phase III and Phase II-B clinical programs and begin clinical trials for our other products.activities. In addition, our expenses could increase beyond expectations if applicable regulatory authorities, including the FDA, require that we perform additional studies to those that we currently anticipate, in which case the timing of any potential product approval may be delayed. As of April 30, 2014,December 31, 2017, we had $58.3$9.5 million of cash, and cash equivalentsincluding the fair value of our marketable securities on hand. Based on our current operating plans, we believe that our existing cash and cash equivalents will be sufficient to fund our projected operating requirements through the fiscalfirst quarter of calendar year ending April 30, 2017.2019. We will need substantial additional capital in the future in order to complete the development and commercialization of levosimendan and Oxycyte and to fund the development and commercialization of future product candidates. Until we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. Such funding, if needed, may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses. As a result of our historical operating losses and expected future negative cash flows from operations, we have concluded that there is substantial doubt about our ability to continue as a going concern. Similarly, the report of our independent registered public accounting firm on our December 31, 2017 Consolidated Financial Statements includes an explanatory paragraph indicating that there is substantial doubt about our ability to continue as a going concern. Substantial doubt about our ability to continue as a going concern may materially and adversely affect the price per share of our common stock and make it more difficult to obtain financing.
 
If adequate funds are not available, we may also be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or to grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. We may also consider strategic alternatives, including a sale of the Company, merger, other business combination or recapitalization.

 
Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:
 
the scope, rate of progress and cost of our clinical trials and other research and development activities;
the scope, rate of progress and cost of our clinical trials and other research and development activities;
-  the costs and timing of regulatory approval;
-  the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
the costs and timing of regulatory approval;

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
- 
the effect of competing technological and market developments;
the terms and timing of any collaboration, licensing or other arrangements that we may establish;
the cost and timing of completion of clinical and commercial-scale manufacturing activities; and
the costs of establishing sales, marketing and distribution capabilities for our cosmetic products and any product candidates for which we may receive regulatory approval.
 
-  the effect of competing technological and market developments;
-  the terms and timing of any collaboration, licensing or other arrangements that we may establish;
-  the cost and timing of completion of clinical and commercial-scale manufacturing activities; and
-  the costs of establishing sales, marketing and distribution capabilities for our cosmetic products and any product candidates for which we may receive regulatory approval.
Risks Related to Commercialization and Product Development
 
Orion may have the right to terminate our license for the levosimendan product, and, if the license is terminated, our business would be materially harmed.
The License grants Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada.  Under the License, if we do not enroll a randomized patient in a human clinical trial using the levosimedan product by July 31, 2014, Orion will have the right to immediately terminate the License.  While we have commenced our clinical trial process, activated trial sites, and expect the enrollment of the first patient at any time, it is possible that the first patient will be enrolled by July 31, 2014.  Accordingly, we intend to seek a waiver or amendment to this condition in the License.  There can be no assurance that we will obtain such a waiver or amendment before July 31, 2014, or at all, which could potentially result in Orion’s termination of the License. If Orion terminates the License, we would not be able to develop or commercialize the levosimedan product.  The loss of our license with Orion with respect to the levosimedan product would have a material adverse effect on our business.
We are limited in the number of products we can simultaneously pursue and therefore our survival depends on our success with a small number of product opportunities.
 
We have limited financial resources, so at present we are primarily focusing these resources on developing levosimendan for the treatment of low cardiac output syndromepulmonary hypertension, in addition to exploring strategic alternatives in order to maximize stockholder value. On January 31, 2017, we announced top-line results from the Phase 3 LEVO-CTS trial for the treatment of LCOS. The study did not achieve statistically significant reductions in the dual endpoint of death or use of a mechanical assist device at 30 days, nor in the quad endpoint of death, myocardial infarction, need for dialysis, or use of a mechanical assist device at 30 days. Nevertheless, the study demonstrated statistically significant reductions in two of three secondary endpoints including reduction in LCOS and our Oxycyte oxygen carrier product. We have delayed development on our Wundecyte topical wound product and Vitavent, our oxygen-carrying liquid, untila reduction in postoperative use of secondary inotropes. Additionally, we findobserved a licensing partner willing to pursue development or obtain additional financing to pursue development ourselves.non-significant numerical reduction in 90-day mortality. At present, we intend to commit most of our resources to advancing levosimendan and Oxycyte to the point it receives regulatory approval for onethe treatment of pulmonary hypertension. If as a consequence of the results of our Phase 3 LEVO-CTS trial or more medical uses, and if this effort is unsuccessfulour Phase 2 trial in PH-HFpEF that we plan to conduct, we are unable to receive regulatory approval of levosimendan, then we may not have resources to pursue development of ourany other products and our business wouldcould terminate. Furthermore, by delaying development of Vitavent, this technology may become obsolete by the time we have sufficient capital to resume development and testing, so the funds expended on this product to date would be lost, as well as our opportunity to benefit if the product could be successfully developed.
Failure to integrate or realize the expected benefits of the Phyxius asset acquisition could adversely affect our business and results of operations.
On November 13, 2013, we completed our acquisition of certain assets of Phyxius Pharma, Inc., or Phyxius.  At the same time, three former employees of Phyxius became employees of our company. We conducted this transaction based on certain assumptions regarding our business, markets, cost structures and synergies. If we do not successfully integrate or realize the anticipated benefits of this transaction, instead of resulting in growth for and enhanced value to our company, our strategy may cause us to experience operational issues and expose us to operational and regulatory risk, each of which could have material adverse effects on our reputation, business, financial condition and results of operations.
 
We currently have no approved drug products for sale and we cannot guarantee that we will ever have marketable drug products.
 
We currently have no approved drug products for sale. The research, testing, manufacturing, labeling, approval, selling, marketing, and distribution of drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a new drug application, or an NDA from the FDA for each product candidate. We have not submitted an NDA or received marketing approval for any of our product candidates. Obtainingcandidates, and obtaining approval of an NDA is a lengthy, expensive and uncertain process. MarketsIn addition, markets outside of the United States also have requirements for approval of drug candidates which we must comply with prior to marketing. Accordingly, we cannot guarantee that we will ever have marketable drug products.
 

Prior to obtaining approval to commercialize a product candidate in the United States or abroad, we or our collaborators must demonstrate with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA, that such product candidates are safe and effective for their intended uses. Results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe the preclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA and other regulatory authorities. Additionally, the FDA may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or it may object to elements of our clinical development program. For example, we held a meeting with the FDA to review the preliminary trial data for our Phase 3 LEVO-CTS trial and discuss a path forward to file an NDA for levosimendan. We explored the opportunity for submitting an NDA for use in CABG surgery patients on the basis of the robust reduction in 90-day mortality observed in the LEVO-CTS trial. However, the FDA advised that another study in CABG surgery patients would be required that prospectively tests levosimendan’s effectiveness in improving mortality. Accordingly, we have suspended development of levosimendan use in CABG due to the scope of the repeat study, as required by the FDA.
The development of levosimendan and Oxycyte is subject to a high level of technological risk.
 
We expect to devotehave devoted a substantial portion of our financial and managerial resources to pursuingpursue Phase III and Phase II3 clinical trials for levosimendan and Oxycyte over the next three years.levosimendan. The biomedical field has undergone rapid and significant technological changes. Technological developments may result in our products becoming obsolete or non-competitive before we are able to recover any portion of the research and development and other expenses we have incurred to develop and clinically test levosimendan and Oxycyte.levosimendan. As our opportunity to generate substantial product revenues within the next fourthree to fivefour years is most likely dependent on successful testing and commercialization of levosimendan and Oxycyte for surgical and oxygen delivery applications,pulmonary hypertension, any such occurrence would have a material adverse effect on our operations and could result in the cessation of our business.
 
10

We may beare required to conduct additional clinical trials in the future, which are expensive and time consuming, and the outcome of the trials is uncertain.
 
We expect to commit a substantial portion of our financial and business resources over the next three years to clinical testing of levosimendan and Oxycyte and advancing these productsthis product to regulatory approval for use in one or more medical applications. All of these clinical trials and testing will be expensive and time consuming and the timing of the regulatory review process is uncertain. The applicable regulatory agencies may suspend clinical trials at any time if they believe that the subjects participating in such trials are being exposed to unacceptable health risks. We cannot ensure that we will be able to complete our clinical trials successfully or obtain FDA or other governmental or regulatory approval of our products, or that such approval, if obtained, will not include limitations on the indicated uses for which our products may be marketed. For example, the top-line results of our Phase 3 LEVO-CTS trial for levosimendan did not achieve statistically significant reductions in dual or quad primary endpoints but did meet two secondary endpoints with statistically significant reduction in incidence of LCOS and use of postoperative secondary inotropes. Our business, financial condition and results of operations are critically dependent on obtaining capital to advance our testing program and receiving FDA and other governmental and regulatory approvals of our products. A significant delay in or failure of our planned clinical trials or a failure to achieve these approvals would have a material adverse effect on us and could result in major setbacks or jeopardize our ability to continue as a going concern. For instance, based on the results of our LEVO-CTS clinical trial and subsequent FDA feedback, we do not anticipate undertaking further development with levosimendan in the LCOS indication.
 
The market may not accept our products.
 
Even if regulatory approval is obtained, there is a risk that the efficacy and pricing of our products, considered in relation to our products’ expected benefits, will not be perceived by health care providers and third-party payers as cost-effective, and that the price of our products will not be competitive with other new technologies or products. Our results of operations may be adversely affected if the price of our products areis not considered cost-effective or if our products do not otherwise achieve market acceptance.
 
Any collaboration we enter with third parties to develop and commercialize our product candidates may place the development of our product candidates outside our control, may require us to relinquish important rights or may otherwise be on terms unfavorable to us.
 
We may enter into collaborations with third parties to develop and commercialize our product candidates, including levosimendan and Oxycyte.candidates. Our dependence on future partners for development and commercialization of our product candidates would subject us to a number of risks, including:
 
-  we may not be able to control the amount and timing of resources that our partners may devote to the development or commercialization of our product candidates or to their marketing and distribution;

 
partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
we may not be able to control the amount and timing of resources that our partners may devote to the development or commercialization of our product candidates or to their marketing and distribution;
disputes may arise between us and our partners that result in the delay or termination of the research, development or commercialization of our product candidates or that result in costly litigation or arbitration that diverts management’s attention and resources;
partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
partners may experience financial difficulties;
disputes may arise between us and our partners that result in the delay or termination of the research, development or commercialization of our product candidates or that result in costly litigation or arbitration that diverts management’s attention and resources;
partners may not properly maintain or defend our intellectual property rights, or may use our proprietary information, in such a way as to invite litigation that could jeopardize or invalidate our intellectual property rights or proprietary information or expose us to potential litigation;
partners may experience financial difficulties;
business combinations or significant changes in a partner’s business strategy may adversely affect a partner’s willingness or ability to meet its obligations under any arrangement;
partners may not properly maintain or defend our intellectual property rights, or may use our proprietary information, in such a way as to invite litigation that could jeopardize or invalidate our intellectual property rights or proprietary information or expose us to potential litigation;
a partner could independently move forward with a competing product candidate developed either independently or in collaboration with others, including our competitors; and
business combinations or significant changes in a partner’s business strategy may adversely affect a partner’s willingness or ability to meet its obligations under any arrangement;
-  the collaborations with our partners may be terminated or allowed to expire, which would delay the development and may increase the cost of developing our product candidates.
a partner could independently move forward with a competing product candidate developed either independently or in collaboration with others, including our competitors; and
the collaborations with our partners may be terminated or allowed to expire, which would delay the development and may increase the cost of developing our product candidates.
 
Delays in the commencement, enrollment and completion of clinical testing could result in increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.
 
Delays in the commencement, enrollment and completion of clinical testing could significantly affect our product development costs. We do not know whether planned clinical trials for levosimendan and Oxycyte will begin on time or be completed on schedule, if at all. The commencement and completion of clinical trials requires us to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other clinical trial programs for the same indication as our product candidates or may be required to withdraw from our clinical trial as a result of changing standards of care or may become ineligible to participate in clinical studies. The commencement, enrollment and completion of clinical trials can be delayed for a variety of other reasons, including delays related to:
 
reaching agreements on acceptable terms with prospective trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among trial sites;
11

obtaining institutional review board, or IRB, approval to conduct a clinical trial at numerous prospective sites;
- 
recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including meeting the enrollment criteria for our study and competition from other clinical trial programs for the same indication as our product candidates;
- 
-  reaching agreements on acceptable terms with prospective contract research organizations, or CROs, and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
maintaining and supplying clinical trial material on a timely basis; and
- 
-  obtaining regulatory approval to commence a clinical trial;
collecting, analyzing and reporting final data from the clinical trials.
-  obtaining institutional review board, or IRB, approval to conduct a clinical trial at numerous prospective sites;
-  recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including meeting the enrollment criteria for our study and competition from other clinical trial programs for the same indication as our product candidates;
-  retaining patients who have initiated a clinical trial but may be prone to withdraw due to the treatment protocol, lack of efficacy, personal issues or side effects from the therapy or who are lost to further follow-up;
-  maintaining and supplying clinical trial material on a timely basis; and
-  collecting, analyzing and reporting final data from the clinical trials.
 
In addition, a clinical trial may be suspended or terminated by us, the FDA or other regulatory authorities due to a number of factors, including:
 
failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;
inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;
unforeseen safety issues or any determination that a trial presents unacceptable health risks; and
unforeseen safety issues or any determination that a trial presents unacceptable health risks; and
-  lack of adequate funding to continue the clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and increased expenses associated with the services of our CROs and other third parties.
lack of adequate funding to continue the clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and increased expenses associated with the services of our contract research organizations, or CROs, and other third parties.
 
Changes in regulatory requirements and guidance may occur and we may need to amend clinical trial protocols to reflect these changes with appropriate regulatory authorities. Amendments may require us to resubmit our clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. If we experience delays in the completion of, or if we terminate, our clinical trials, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenues will be delayed. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Even if we are able to ultimately commercialize our product candidates, other therapies for the same or similar indications may have been introduced to the market and established a competitive advantage.
 

Risks Relating to Regulatory Matters
 
Our activities are and will continue to be subject to extensive government regulation, which is expensive and time consuming, and we will not be able to sell our products without regulatory approval.
 
Our research, development, testing, manufacturing, marketing and distribution of levosimendan and Oxycyte are,is, and will continue to be, subject to extensive regulation, monitoring and approval by the FDA and other regulatory agencies. There are significant risks at each stage of the regulatory scheme.
 
Product approval stage
 
During the product approval stage, we attempt to prove the safety and efficacy of our product for its indicated uses. There are numerous problems that could arise during this stage, including:
 
The data obtained from laboratory testing and clinical trials are susceptible to varying interpretations, which could delay, limit or prevent FDA and other regulatory approvals;
the data obtained from laboratory testing and clinical trials are susceptible to varying interpretations, which could delay, limit or prevent FDA and other regulatory approvals;
Adverse events could cause the FDA and other regulatory authorities to halt trials;
adverse events could cause the FDA and other regulatory authorities to halt trials;
At any time the FDA and other regulatory agencies could change policies and regulations that could result in delay and perhaps rejection of our products; and
at any time the FDA and other regulatory agencies could change policies and regulations that could result in delay and perhaps rejection of our products; and
-  Even
even after extensive testing and clinical trials, there is no assurance that regulatory approval will ever be obtained for any of our products.
12

Commercialization approval stage
We will be required to file a BLA of an NDA with the FDA in order to obtain regulatory approval for the commercial production and sale of our product candidates in the United States and similar applications with regulatory authorities in countries where we seek to commercialize our product candidates. Under FDA guidelines, the FDA may comment upon the acceptability of the applicable application following its submission. After an application is submitted, there is an initial review to be sure that all of the required elements are included in the submission. There can be no assurance that the submissionregulatory approval will ever be acceptedobtained for filing or that the FDA may not issue an RTF. If an RTF is issued, there is opportunity for dialogue between the sponsor and the FDA in an effort to resolve all concerns. There can be no assurance that such a dialogue will be successful in leading to the filingany of the BLA or NDA. If the submission is filed, there can be no assurance that the full review will result in product approval.our products.
 
Post-commercialization stage
 
Discovery of previously unknown problems with our products, or unanticipated problems with our manufacturing arrangements, even after FDA and other regulatory approvals of our products for commercial sale may result in the imposition of significant restrictions, including withdrawal of the product from the market.
 
Additional laws and regulations may also be enacted that could prevent or delay regulatory approval of our products, including laws or regulations relating to the price or cost-effectiveness of medical products. Any delay or failure to achieve regulatory approval of commercial sales of our products is likely to have a material adverse effect on our financial condition, results of operations and cash flows.
 
The FDA and other regulatory agencies continue to review products even after they receive agency approval. If and when the FDA or another regulatory agency outside the United States approves one of our products, its manufacture and marketing will be subject to ongoing regulation, which could include compliance with current good manufacturing practices, adverse event reporting requirements and general prohibitions against promoting products for unapproved or “off-label” uses. We are also subject to inspection and market surveillance by the FDA for compliance with these and other requirements. Any enforcement action resulting from failure, even by inadvertence, to comply with these requirements could affect the manufacture and marketing of Oxycytelevosimendan or our other products. In addition, the FDA or other regulatory agencies could withdraw a previously approved product from the market upon receipt of newly discovered information. The FDA or another regulatory agency could also require us to conduct additional, and potentially expensive, studies in areas outside our approved indicated uses.
 
We must continually monitor the safety of our products once approved and marketed for signs that their use may elicit serious and unexpected side effects and adverse events, which could jeopardize our ability to continue marketing the products. We may also be required to conduct post-approval clinical studies as a condition to licensing a product.
 
As with all pharmaceutical products, the use of our products could sometimes produce undesirable side effects or adverse reactions or events (referred to cumulatively as adverse events). For the most part, we would expect these adverse events to be known and occur at some predicted frequency. When adverse events are reported to us, we will be required to investigate each event and circumstances surrounding it to determine whether it was caused by our product and whether it implies that a previously unrecognized safety issue exists. We will also be required to periodically report summaries of these events to the applicable regulatory authorities.
 

In addition, the use of our products could be associated with serious and unexpected adverse events, or with less serious reactions at a greater than expected frequency. This may be especially true when our products are used in critically ill or otherwise compromised patient populations. When these unexpected events are reported to us, we will be required to make a thorough investigation to determine causality and implications for product safety. These events must also be specifically reported to the applicable regulatory authorities. If our evaluation concludes, or regulatory authorities perceive, that there is an unreasonable risk associated with the product, we would be obligated to withdraw the impacted lot(s) of that product. Furthermore, an unexpected adverse event of a new product could be recognized only after extensive use of the product, which could expose us to product liability risks, enforcement action by regulatory authorities and damage to our reputation and public image.
 
A serious adverse finding concerning the risk of our products by any regulatory authority could adversely affect our reputation, business and financial results.
 
13

When a new product is approved, the FDA or other regulatory authorities may require post-approval clinical trials, sometimes called Phase IV4 clinical trials. If the results of such trials are unfavorable, this could result in the loss of the license to market the product, with a resulting loss of salessales.
 
After our products are commercialized, we expect to spend considerable time and money complying with federal and state laws and regulations governing their sale, and, if we are unable to fully comply with such laws and regulations, we could face substantial penalties.
 
Health care providers, physicians and others will play a primary role in the recommendation and prescription of our clinical products. Our arrangements with third-party payers and customers may expose us to broadly applicable fraud and abuse and other health care laws and regulations that may constrain the business or financial arrangements and relationships through which we will market, sell and distribute our products. Applicable federal and state health care laws and regulations are expected to include, but not be limited to, the following:
 
The federal anti-kickback statute is a criminal statute that makes it a felony for individuals or entities knowingly and willfully to offer or pay, or to solicit or receive, direct or indirect remuneration, in order to induce the purchase, order, lease, or recommending of items or services, or the referral of patients for services, that are reimbursed under a federal health care program, including Medicare and Medicaid;

The federal False Claims Act imposes liability on any person who knowingly submits, or causes another person or entity to submit, a false claim for payment of government funds. Penalties include three times the government’s damages plus civil penalties of $5,500 to $11,000 per false claim. In addition, the False Claims Act permits a person with knowledge of fraud, referred to as a qui tam plaintiff, to file a lawsuit on behalf of the government against the person or business that committed the fraud, and, if the action is successful, the qui tam plaintiff is rewarded with a percentage of the recovery;

Some state laws also require pharmaceutical companies to comply with certain price reporting and other compliance requirements.
many states have analogous state laws and regulations, such as state anti-kickback and false claims laws, which, in some cases, these state laws impose more strict requirements than the federal laws and may require pharmaceutical companies to comply with certain price reporting and other compliance requirements.
 
Our failure to comply with any of these federal and state health care laws and regulations, or health care laws in foreign jurisdictions, could have a material adverse effect on our business, financial condition, result of operations and cash flows.
 

Health care reform and controls on health care spending may limit the price we can charge for our products and the amount we can sell.
 
As a result of Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act of 2010, (collectively,collectively, the “ACA”)ACA, enacted in March 2010, substantial changes have occurred and are expected to continue to occur in the system for paying for health care in the United States, including changes made in order to extend medical benefits to those who currently lack insurance coverage. This comprehensive health care reform legislation also included provisions to control health care costs and improve health care quality. Together with ongoing statutory and budgetary policy developments at a federal level, this health care reform legislation could include changes in Medicare and Medicaid payment policies and other health care delivery administrative reforms that could potentially negatively impact our business. Because not all the administrative rules implementing health care reform under the legislation have been finalized, and because of ongoing federal fiscal budgetary pressures not yet resolved for federal health programs, the full impact of the ACA and of further statutory actions to reform healthcare payment on our business is unknown, but there can be no assurances that health care reform legislation will not adversely impact either our operational results or the manner in which we operate our business. There have been judicial and Congressional challenges to the ACA and there may be additional challenges and amendments to the ACA in the future, particularly in light of the current presidential administration and U.S. Congress. For example, the Tax Cuts and Jobs Act enacted on December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of the Internal Revenue Code, commonly referred to as the individual mandate, beginning in 2019, and on October 13, 2017, President Trump signed an executive order terminating the cost-sharing subsidies that reimburse the insurers under the ACA. We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement, and in additional downward pressure on the price that we receive for any approved product. Cost of care could be reduced by reducing the level of reimbursement for medical services or products (including those biopharmaceuticals that we intend to produce and market), or by restricting coverage (and, thereby, utilization) of medical services or products. In either case, a reduction in the utilization of, or reimbursement for, our products could have a materially adverse impact on our financial performance. Moreover, recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their commercial products. We cannot predict what healthcare reform initiatives may be adopted in the future.
 
14

Uncertainty of third-party reimbursement could affect our future results of operations.
 
Sales of medical products largely depend on the reimbursement of patients’ medical expenses by governmental health care programs and private health insurers. We will be required to report detailed pricing information, net of included discounts, rebates and other concessions, to the Centers for Medicare and Medicaid Services, or CMS, for the purpose of calculating national reimbursement levels, certain federal prices, and certain federal rebate obligations. If we report pricing information that is not accurate to the federal government, we could be subject to fines and other sanctions that could adversely affect our business. In addition, the government could change its calculation of reimbursement, federal prices, or federal rebate obligations which could negatively impact us. There is no guarantee that government health care programs or private health insurers will reimburse for the sales of our products, or permit us to sell our products at high enough prices to generate a profit.
 
Governments outside the United States tend to impose strict price controls and reimbursement approval policies, which may adversely affect our prospects for generating revenue outside the United States.
 
In some countries, particularly European Union countries and Canada, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time (6 to 12 months or longer) after the receipt of marketing approval for a product. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. To obtain or maintain reimbursement or pricing approval in some countries with respect to any product candidate that achieves regulatory approval, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products upon approval, if at all, is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our prospects for generating revenue, if any, could be adversely affected which would have a material adverse effect on our business and results of operations. Further, if we achieve regulatory approval of any product, we must successfully negotiate product pricing for such product in individual countries. As a result, the pricing of our products, if approved, in different countries may vary widely, thus creating the potential for third-party trade in our products in an attempt to exploit price differences between countries. This third-party trade of our products could undermine our sales in markets with higher prices.
 
Risks Relating to Our Dependence on Third Parties
 
We depend on third parties to manufacture our products.
 
We do not own or operate any manufacturing facilities for the commercial-scale production of our products. Instead, we rely on third party manufacturers.  For example, Orion produces levosimendan for us, Bioserve currently manufacturers Oxycyte for us and Fluoromed currently produces FtBu for us. Accordingly, a delay in achieving scale-up of commercial manufacturing capabilities when needed will have a material adverse effect on salespursuant to the terms of our products. Additionally, the manufacturelicense for levosimendan, Orion is our sole manufacturing source for levosimendan.  Accordingly, our business is susceptible to disruption, and our results of operations can be adversely affected, by any disruption in supply or other adverse developments in our products will be subjectrelationship with Orion.  If supply from Orion is delayed or terminated, or if its facilities suffer any damage or disruption, we may need to extensive government regulation. Among the conditions for marketing approval is that our quality control and manufacturing procedures conform to applicable good manufacturing practice regulations. There is a risk that we will not be able to obtain the necessary regulatory clearances or approvals to manufacture our products onsuccessfully qualify an alternative supplier in a timely basis or at all.
A changemanner in order to not disrupt our business.  If we cannot obtain an alternate manufacturer likelyin a timely manner, we would require formal approval by the FDA or other regulatory agencies before the new manufacturer could produce commercial supplies of our products. This approval process would likely take at least 12 to 18 months and, during that time, we could faceexperience a shortage ofsignificant interruption in supply of our products,levosimendan, which could negatively affect our financial condition, results of operations and cash flows.

 
We depend on the services of a limited number of key personnel.
 
Our success is highly dependent on the continued services of a limited number of scientists and support personnel. The loss of any of these individuals, in particular, John P. Kelley,Michael Jebsen, our Interim Chief Executive Officer and Chief Financial Officer, could have a material adverse effect on us. In addition, our success will depend, among other factors, on the recruitment and retention of additional highly skilled and experienced management and technical personnel. There is a risk that we will not be able to retain existing employees or to attract and retain additional skilled personnel on acceptable terms given the competition for such personnel among numerous large and well-funded pharmaceutical and health care companies, universities, and non-profit research institutions, which could negatively affect our financial condition, results of operations and cash flows.
 
15

We have limited experience in the sale and marketing of medical products.
 
We have limited experience in the sale and marketing of approved medical products and marketing the licensing of such products before FDA or other regulatory approval. We have not decided upon a commercialization strategy in these areas. We do not know of any third party that is prepared to distribute our products should they be approved. If we decide to establish our own commercialization capability, we will need to recruit, train and retain a marketing staff and sales force with sufficient technical expertise. We do not know whether we can establish a commercialization program at a cost that is acceptable in relation to revenue or whether we can be successful in commercializing our product. Factors that may inhibit our efforts to commercialize our products directly and without strategic partners include:
 
Our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
The inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe our products;
the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe our products;
The lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and
the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and
-  Unforeseen costs and expenses associated with creating and sustaining an independent sales and marketing organization.
unforeseen costs and expenses associated with creating and sustaining an independent sales and marketing organization.
 
Failure to successfully commercialize our products or to do so on a cost effective basis would likely result in failure of our business.
 
We may enter into distribution arrangements and marketing alliances for certain products and any failure to successfully identify and implement these arrangements on favorable terms, if at all, may impair our ability to commercialize our product candidates.
 
We do not anticipate having the resources in the foreseeable future to develop global sales and marketing capabilities for all of the products we develop, if any. We may pursue arrangements regarding the sales and marketing and distribution of one or more of our product candidates and our future revenues may depend, in part, on our ability to enter into and maintain arrangements with other companies having sales, marketing and distribution capabilities and the ability of such companies to successfully market and sell any such products. Any failure to enter into such arrangements and marketing alliances on favorable terms, if at all, could delay or impair our ability to commercialize our product candidates and could increase our costs of commercialization. Any use of distribution arrangements and marketing alliances to commercialize our product candidates will subject us to a number of risks, including the following:
 
-  We may be required to relinquish important rights to our products or product candidates;
we may be required to relinquish important rights to our products or product candidates;
we may not be able to control the amount and timing of resources that our distributors or collaborators may devote to the commercialization of our product candidates;
our distributors or collaborators may experience financial difficulties;
our distributors or collaborators may not devote sufficient time to the marketing and sales of our products; and
business combinations or significant changes in a collaborator’s business strategy may adversely affect a collaborator’s willingness or ability to complete its obligations under any arrangement.
 
-  We may not be able to control the amount and timing of resources that our distributors or collaborators may devote to the commercialization of our product candidates;
-  Our distributors or collaborators may experience financial difficulties;
-  Our distributors or collaborators may not devote sufficient time to the marketing and sales of our products; and
-  Business combinations or significant changes in a collaborator’s business strategy may adversely affect a collaborator’s willingness or ability to complete its obligations under any arrangement.

 
We may need to enter into additional co-promotion arrangements with third parties where our own sales force is neither well situated nor large enough to achieve maximum penetration in the market. We may not be successful in entering into any co-promotion arrangements, and the terms of any co-promotion arrangements we enter into may not be favorable to us.
 
Risks Relating to Intellectual Property
 
It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.
 
Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our product candidates and the methods used to manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing our products is dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.
 
16

We license certain intellectual property from third parties that covers our product candidates. We rely on certain of these third parties to file, prosecute and maintain patent applications and otherwise protect the intellectual property to which we have a license, and we have not had and do not have primary control over these activities for certain of these patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. Our enforcement of certain of these licensed patents or defense of any claims asserting the invalidity of these patents would also be subject to the cooperation of the third parties.
 
The patent positions of pharmaceutical and biopharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in biopharmaceutical patents has emerged to date in the United States. The biopharmaceutical patent situation outside the United States is even more uncertain. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in the patents we own or to which we have a license from a third-party. Further, if any of our patents are deemed invalid and unenforceable, it could impact our ability to commercialize or license our technology.
 
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
 
others may be able to make compositions or formulations that are similar to our product candidates but that are not covered by the claims of our patents;
others may be able to make compositions or formulations that are similar to our product candidates but that are not covered by the claims of our patents;
we might not have been the first to make the inventions covered by our issued patents or pending patent applications;
we might not have been the first to make the inventions covered by our issued patents or pending patent applications;
we might not have been the first to file patent applications for these inventions;
we might not have been the first to file patent applications for these inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies;
others may independently develop similar or alternative technologies or duplicate any of our technologies;
it is possible that our pending patent applications will not result in issued patents;
it is possible that our pending patent applications will not result in issued patents;
our issued patents may not provide us with any competitive advantages, or may be held invalid or unenforceable as a result of legal challenges by third parties;
our issued patents may not provide us with any competitive advantages, or may be held invalid or unenforceable as a result of legal challenges by third parties;
we may not develop additional proprietary technologies that are patentable; or
we may not develop additional proprietary technologies that are patentable; or
-  the patents of others may have an adverse effect on our business.
the patents of others may have an adverse effect on our business.
 
We also may rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

 
We rely on confidentiality agreements that, if breached, may be difficult to enforce and could have a material adverse effect on our business and competitive position.
 
Our policy is to enter agreements relating to the non-disclosure and non-use of confidential information with third parties, including our contractors, consultants, advisors and research collaborators, as well as agreements that purport to require the disclosure and assignment to us of the rights to the ideas, developments, discoveries and inventions of our employees and consultants while we employ them. However, these agreements can be difficult and costly to enforce. Moreover, to the extent that our contractors, consultants, advisors and research collaborators apply or independently develop intellectual property in connection with any of our projects, disputes may arise as to the proprietary rights to the intellectual property. If a dispute arises, a court may determine that the right belongs to a third party, and enforcement of our rights can be costly and unpredictable. In addition, we rely on trade secrets and proprietary know-how that we seek to protect in part by confidentiality agreements with our employees, contractors, consultants, advisors or others. Despite the protective measures we employ, we still face the risk that:
 
These agreements may be breached;
these agreements may be breached;
These agreements may not provide adequate remedies for the applicable type of breach; or
these agreements may not provide adequate remedies for the applicable type of breach; or
-  Our
our trade secrets or proprietary know-how will otherwise become known.
17

 
Any breach of our confidentiality agreements or our failure to effectively enforce such agreements would have a material adverse effect on our business and competitive position.
 
We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to protect our rights to, or use, our technology.
 
If we or our partners choose to go to court to stop someone else from using the inventions claimed in our patents, that individual or company has the right to ask the court to rule that these patents are invalid and/or should not be enforced against that third party. These lawsuits are expensive and would consume time and other resources even if we were successful in stopping the infringement of these patents. In addition, there is a risk that the court will decide that these patents are not valid and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity of these patents is upheld, the court will refuse to stop the other party on the ground that such other party’s activities do not infringe our rights to these patents.
 
Furthermore, a third party may claim that we or our manufacturing or commercialization partners are using inventions covered by the third party’s patent rights and may go to court to stop us from engaging in our normal operations and activities, including making or selling our product candidates. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and technical personnel. There is a risk that a court would decide that we or our commercialization partners are infringing the third party’s patents and would order us or our partners to stop the activities covered by the patents. In addition, there is a risk that a court will order us or our partners to pay the other party damages for having violated the other party’s patents. We have agreed to indemnify certain of our commercial partners against certain patent infringement claims brought by third parties. The biotechnology industry has produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods of use either does not infringe the patent claims of the relevant patent and/or that the patent claims are invalid, and we may not be able to do this. Proving invalidity, in particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.
 
Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications covering technology similar to ours. Any such patent application may have priority over our patent applications or patents, which could further require us to obtain rights to issued patents by others covering such technologies. If another party has filed a U.S. patent application on inventions similar to ours, we may have to participate in an interference proceeding declared by the U.S. Patent and Trademark Office, or USPTO, to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of our U.S. patent position with respect to such inventions.
 
Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.

 
Our collaborations with outside scientists and consultants may be subject to restriction and change.
 
We work with chemists, biologists and other scientists at academic and other institutions, and consultants who assist us in our research, development, regulatory and commercial efforts, including the members of our scientific advisory board. These scientists and consultants have provided, and we expect that they will continue to provide, valuable advice on our programs. These scientists and consultants are not our employees, may have other commitments that would limit their future availability to us and typically will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, we will be unable to prevent them from establishing competing businesses or developing competing products. For example, if a key scientist acting as a principal investigator in any of our clinical trials identifies a potential product or compound that is more scientifically interesting to his or her professional interests, his or her availability to remain involved in our clinical trials could be restricted or eliminated.
 
18

Under current law, we may not be able to enforce all employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.
 
We have entered into non-competition agreements with certain of our employees. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. Under current law, we may be unable to enforce these agreements against certain of our employees and it may be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us. If we cannot enforce our employees’ non-compete agreements, we may be unable to prevent our competitors from benefiting from the expertise of our former employees.
 
We may infringe or be alleged to infringe intellectual property rights of third parties.
 
Our products or product candidates may infringe on, or be accused of infringing on, one or more claims of an issued patent or may fall within the scope of one or more claims in a published patent application that may be subsequently issued and to which we do not hold a license or other rights. Third parties may own or control these patents or patent applications in the United States and abroad. These third parties could bring claims against us or our collaborators that would cause us to incur substantial expenses and, if successful against us, could cause us to pay substantial damages. Further, if a patent infringement suit were brought against us or our collaborators, we or they could be forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of the suit.
 
If we are found to infringe the patent rights of a third party, or in order to avoid potential claims, we or our collaborators may choose or be required to seek a license from a third party and be required to pay license fees or royalties or both. These licenses may not be available on acceptable terms, or at all. Even if we or our collaborators were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent infringement claims, we or our collaborators are unable to enter into licenses on acceptable terms.
 
There have been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical and biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other proceedings, including interference proceedings declared by the United States Patent and Trademark OfficeUSPTO and opposition proceedings in the European Patent Office, regarding intellectual property rights with respect to our products. Our products, after commercial launch, may become subject to Paragraph IV certification under the Hatch-Waxman Act, thus forcing us to initiate infringement proceedings against such third-party filers. The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time.

 
Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We try to ensure that our employees do not use the proprietary information or know-how of others in their work for us. We may, however, be subject to claims that we or these employees have inadvertently or otherwise used or disclosed intellectual property, trade secrets or other proprietary information of any such employee’s former employer. Litigation may be necessary to defend against these claims and, even if we are successful in defending ourselves, could result in substantial costs to us or be distracting to our management. If we fail to defend any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel.
 
Product liability lawsuits against us could cause us to incur substantial liabilities, limit sales of our existing products and limit commercialization of any products that we may develop.
 
Our business exposes us to the risk of product liability claims that are inherent in the manufacturing, distribution, and sale of biotechnology products. We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and an even greater risk when we commercially sell any products. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:
 
decreased demand for our products and any product candidates that we may develop;
19

injury to our reputation;
- 
withdrawal of clinical trial participants;
- 
-  Decreased demand for our products and any product candidates that we may develop;
costs to defend the related litigation;
- 
-  Injury to our reputation;
substantial monetary awards to trial participants or patients;
- 
-  Withdrawal of clinical trial participants;
loss of revenue; and
- 
-  Costs to defend the related litigation;
the inability to commercialize any products that we may develop.
-  Substantial monetary awards to trial participants or patients;
-  Loss of revenue; and
-  The inability to commercialize any products that we may develop.
 
We currently maintain limited product liability insurance coverage for our clinical trials in the total amount of $3 million. However, our profitability will be adversely affected by a successful product liability claim in excess of our insurance coverage. There can be no assurance that product liability insurance will be available in the future or be available on reasonable terms.
 
Our business and operations would suffer in the event of computer system failures, cyber-attacks or deficiencies in our cyber-security.
Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur material legal claims and liability, and damage to our reputation, and the further development of our product candidates could be delayed.
Our disclosure controls and procedures address cybersecurity and include elements intended to ensure that there is an analysis of potential disclosure obligations arising from security breaches. We also maintain compliance programs to address the potential applicability of restrictions against trading while in possession of material, nonpublic information generally and in connection with a cyber-security breach. However, a breakdown in existing controls and procedures around our cyber-security environment may prevent us from detecting, reporting or responding to cyber incidents in a timely manner and could have a material adverse effect on our financial position and value of our stock.

On April 30, 2014December 31, 2017 the last closing price of our common stock was $4.88$9.80, as compared with $5.00to $39.00 as of April 30, 2013.December 31, 2016. During the twelve monthsyear ended April 30, 2014,December 31, 2017, the lowest closing price offor our common stock was $1.23$6.40 and the highest closing price was $8.38, all$50.00. All stock prices are as adjusted for the 1-for-20 reverse stock split effective on May 10, 2013.February 23, 2018 at 5:00 p.m.
 
Some companies that have had volatile market prices for their securities have had securities class action lawsuits filed against them. Such lawsuits, should they be filed against us in the future, could result in substantial costs and a diversion of management’s attention and resources. This could have a material adverse effect on our business, results of operations and financial condition.
 
Our failure to maintain compliance with Nasdaq’s continued listing requirements could result in the delisting of our common stock.
Our common stock is currently listed on The Nasdaq Capital Market. In order to maintain this listing, we must satisfy minimum financial and other requirements. In the past, we have received a notification letter from Nasdaq indicating that we were not in compliance with listing requirements because the minimum bid price of our common stock closed below $1.00 per share for 30 consecutive business days. However, Nasdaq subsequently notified us that we had regained compliance with the minimum bid price requirement. If we fail to satisfy Nasdaq’s listing requirements in the future, we expect to take actions to regain compliance, but we can provide no assurance that any such action would prevent our common stock from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements. If our common stock is delisted from Nasdaq, the delisting could substantially decrease trading in our common stock and adversely affect the market liquidity of our common stock; adversely affect our ability to obtain financing on acceptable terms, if at all; and may result in the potential loss of confidence by investors, suppliers, customers, and employees and fewer business development opportunities. Additionally, the market price of our common stock may decline further, and stockholders may lose some or all of their investment.

We are likely to attempt to raise additional capital through issuances of debt or equity securities, which may cause our stock price to decline, dilute the ownership interests of our existing stockholders, and/or limit our financial flexibility.
 
Historically we have financed our operations through the issuance of equity securities and debt financings, and we expect to continue to do so for the foreseeable future. As of April 30, 2014,December 31, 2017, we had $58.3$9.5 million of cash and cash equivalents on hand. Based on our current operating plans, we believe that our existing cash and cash equivalents are sufficient to continue to fund operations through our fiscalthe first quarter of calendar year ending April 30, 2017.2019. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution of their ownership interests. Debt financing, if available, may involve restrictive covenants that limit our financial flexibility or otherwise restrict our ability to pursue our business strategies. Additionally, if we issue shares of common stock, or securities convertible or exchangeable for common stock, the market price of our existing common stock may decline. There can be no assurance that we will be successful in obtaining any additional capital resources in a timely manner, on favorable terms, or at all.
 
20

We have issued in the past, and may issue in the future, substantial amounts of instruments that are convertible into or exercisable for common stock, and our existing stockholders may face substantial dilution if such instruments are converted or exercised.
 
As of July 24, 2014,March 26, 2018, we had outstanding warrants and options, securities purchase agreements, and other instruments that are exercisable into an aggregate of 6,267,850309,517 shares of our common stock, which, if exercised, would represent approximately 18% of our current outstanding common stock. These instruments carry a wide variety of different terms and prices, and there can be no assurance as to when or whether exercises of these instruments may occur. If all or any substantial portion of these instruments are exercised, our existing stockholders may face substantial dilution of their ownership interests. 
 
Certain investors may be able to exercise significant influence over us.
As of July 24, 2014, SPC 1 Vatea Segregated Portfolio, or Vatea Fund, held 189,082 shares of our common stock and JP SPC 3 obo OXBT FUND, SP, or OXBT Fund, held 3,192,593 shares of our common stock, representing 12% of our outstanding common stock. As of July 24, 2014, OXBT Fund held warrants that are exercisable into an aggregate of up to 2,251,742 shares of our common stock, which, if exercised, would represent 18.6% of our current outstanding common stock. Mr. Gregory Pepin, one of our directors, is the investment manager of both Vatea Fund and OXBT Fund. In addition, as of July 24, 2014, each of John P. Kelly, Doug Randall and Douglas Hay, PhD, our Chief Executive Officer, Vice President, Business and Commercial Operations and Vice President, Regulatory Affairs, respectively, held 1,166,511 shares of our common stock, individually representing 4.2% of our outstanding common stock.  As of July 24, 2014, each of Mr. Kelley, Mr. Randall and Dr. Hay also hold options to purchase 893,220 shares of our common stock, individually representing 3.1% of our outstanding common stock. Accordingly, these parties, either individually or as part of a group, may have a strong ability to influence our business, policies and affairs.  We cannot be certain that their interests will be consistent with the interests of other holders of our common stock.
Risks Relating to Employee Matters and Managing Growth
We may need to increase the size of our company, and we may experience difficulties in managing growth.
As of July 24, 2014, we had 14 full-time employees. We may need to expand our managerial, operational, administrative, financial and other resources in order to manage and fund our operations and clinical trials, continue our development activities and commercialize our product candidates. To support this growth, we may hire additional employees within the next 12 months. Our management, personnel, systems and facilities currently in place may not be adequate to support this future growth. Our need to effectively manage our operations, growth and various projects requires that we continue to improve our operational, financial and management controls, reporting systems and procedures.
We may not be able to attract or retain qualified management and scientific personnel in the future. If we are unable to attract and retain necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede our achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.
In addition, we have scientific and clinical advisors who assist us in our product development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us, or may have arrangements with other companies to assist in the development of products that may compete with ours. Because our business depends on certain key personnel and advisors, the loss of such personnel and advisors could weaken our management team and we may experience difficulty in attracting and retaining qualified personnel and advisors.

These mechanical components of pulmonary venous congestion may trigger pulmonary vasoconstriction, decreased nitric oxide availability, increased endothelin expression, desensitization to license fees earned in accordance with our distribution agreement for Dermacyte for the year ended April 30, 2013.natriuretic peptide induced vasodilation, and vascular remodeling.  Finally, these changes often lead to advanced pulmonary vascular disease, increased right ventricle, or RV, afterload, and RV failure.
 
Gross profit
PH-HFpEF is a common form of pulmonary hypertension with an estimated US prevalence exceeding 1.5 million patients. Currently, no pharmacologic therapies are approved for treatment of PH-HFpEF.  Despite the fact that many therapies have been studied in PH-HFpEF patients, including therapies approved to treat pulmonary arterial hypertension patients, no therapies have been shown to be effective in treating PH-HFpEF patients.
Published pre-clinical and clinical studies indicate that levosimendan may provide important benefits to patients with pulmonary hypertension. Data from these published trials indicate that levosimendan may reduce pulmonary vascular resistance and improve important cardiovascular hemodynamics such as reduced pulmonary capillary wedge pressure in patients with pulmonary hypertension. While none of these studies have focused specifically on PH-HFpEF patients, the general hemodynamic improvements in these published studies of various types of pulmonary hypertension provide an indication that levosimendan may be beneficial in PH-HFpEF patients.
We plan to meet with the FDA to discuss the design of a percentageproposed Phase 2 trial in PH-HFpEF patients during the first half of revenue was (404) %2018. Following feedback from that meeting, we plan to complete the design of the Phase 2 trial and 53% for year ended April 30, 2014 and 2013, respectively. The decrease forbegin enrollment of the year ended April 30, 2014, as compared to the same periodtrial in the prior year, was duesecond half of 2018.
Additionally, our Board of Directors is conducting a comprehensive review of strategic alternatives focused on maximizing stockholder value and has formed a strategic committee of three independent board members to the write-down of Dermacyte productsupervise management in this review. We have engaged Ladenburg Thalmann & Co. Inc. as our financial advisor to assist in the current year thatstrategic review process; including, but not limited to a merger, a business combination, or a purchase, license or other acquisition of assets. This process may not result in any transaction and we do not intend to disclose additional details unless and until we determine further disclosure is no longer being marketed for sale.
Government Grant Revenueappropriate or required.
 
Grant Revenue is recognized as milestones underOpportunities and Trends
As we focus on the Grant programdevelopment of our existing product candidate, we also continue to position ourselves to execute upon licensing and other partnering opportunities. To do so, we will need to continue to maintain our strategic direction, manage and deploy our available cash efficiently and strengthen our collaborative research development and partner relationships.
During 2018, we are achieved. Grant Revenue is earned through reimbursements forfocused on the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.following initiatives:

Government grant revenue $262,995  $1,141,356  $(878,361)  (77) %
For the year ended April 30, 2014, we recorded approximately $263,000 in revenue under the grant program as compared to approximately $1.1 million in revenue during the same period in the prior year. In addition to the revenue earned, we have recorded approximately $124,000 in deferred revenue associated with the grant. Deferred revenue under the grant represents pass-through costs that have been reimbursed in advance of performing the studies underlying the subcontracts. The decrease in revenue earned under the grant is due primarily to our completion of multiple studies in the prior year.
Marketing and Sales Expenses
Marketing and sales expenses consisted primarily of personnel-related costs, including salaries, commissions, and the costs of marketing programs aimed at increasing revenue, such as advertising, trade shows, public relations and other market development programs. Marketing and sales expenses and percentage changes for the year ended April 30, 2014 and 2013, respectively, are as follows:

The personnel costs attributable to Mr. Kelley, Mr. Jebsen, Mr. Randall and Dr. Hay reflect option grants made pursuant to their respective employment agreements, which were negotiated in connection with our acquisition of a license for levosimendan. In addition, Mr. Jebsen was paid a discretionary bonus consisting of $225,000 in cash and 32,143 shares of restricted common stock in recognition of his service as interim Chief Executive Officer from August 2011 through November 2013.

-  Audit and accounting fees increased approximately $55,000 due to the costs incurred for valuation services related to the Phyxius acquisition and the filing of registration statements in the current year.

Audit and accounting fees decreased approximately $53,000 in the current year. This decrease was due primarily to the costs incurred for the change in our fiscal year, which necessitated the filing of our audited transitional financial statements in the prior year which were not incurred in the current period.
-  Investor relation fees increased approximately $560,000 for the costs of outsourced corporate communications firms, road shows and attending investor conferences.
-  
Costs associated with investor relations and communication decreased approximately $47,000 in the current period. This decrease was due primarily to fees paid to a third-party investor relations firm providing marketing and corporate communications services to us in the prior year, which were not incurred in the current year.
-  Legal fees decreased approximately $40,000 due primarily to approximately $285,000 in fees incurred in the prior year for litigation defense costs, partially offset by an increase of approximately $245,000 in fees related to the Phyxius acquisition and the filing of registration statements in the current year.
-  
Consulting fees decreased approximately $129,000 in the current period. This decrease was due primarily to the fees paid to third-party firms for pre-launch commercialization preparations for LCOS, nationwide registrations for drug distribution and market analysis and research for septic shock in the prior year which were not incurred in the current period, partially offset by an increase in fees paid for medical consulting services in the current period.
-  Recruiting fees decreased approximately $25,000 due to headcount additions in the prior year.
-  
Board of Directors fees decreased in the current period by approximately $77,000. This decrease was due primarily to a reduction in the recognized expense for the vesting of stock options awarded in the current year as compared to the recognized expense for stock options awarded in the prior year.
-  
Legal fees increased in the current year by approximately $156,000. This increase was due primarily to additional costs incurred in the current year related to our evaluation of strategic alternatives as directed by our Board of Directors which were not incurred in the prior year.

The LEVO-CTS trial was completed in December of 2016. Based on the data from the trial, levosimendan, given prophylactically prior to cardiac surgery to patients with reduced left ventricular function, had no effect on the co-primary outcomes. The study did not achieve statistically significant reductions in the dual endpoint of death or use of a mechanical assist device at 30 days, nor in the quad endpoint of death, myocardial infarction, need for dialysis, or use of a mechanical assist device at 30 days. Based on the results of the LEVO-CTS trial and subsequent FDA feedback we do not anticipate additional development of levosimendan for the treatment of LCOS in patients undergoing cardiac surgery. As of December 31, 2016, management determined the IPR&D asset, and corresponding Goodwill, was more than temporarily impaired.
 
Other income, and expensenet
Other income includes non-operating income and expense items not otherwise recorded in our consolidated statement of operations.operations and comprehensive loss. These items include, but are not limited to, revenue earned under sublease agreements for our California facility, changes in the fair value of financial assets and liabilities, interest income earned and fixed asset disposals.

Other expense increased approximately $730,000 for the year ended April 30, 2014December 31, 2017 compared to the prior yearyear. This decrease is due primarily due to the change in the recognized fair value of our Series C warrant derivative liability in the current year and a reduction in the interest earned on our investment in marketable securities as compared to the prior year.
During the year ended December 31, 2017, we recorded a derivative gain of approximately $192,000 which compared to a derivative gain of approximately $298,000 in the prior year. These charges to income are derived from the free-standing Series C warrants which are measured at their fair market value each period using the Monte Carlo simulation model.
During the year ended December 31, 2017, we recorded interest income of approximately $174,000 from our investments in marketable securities. This income is derived from approximately $353,000 in bond interest paid, partially offset by approximately $188,000 in charges for amortization of premiums paid and fair-value adjustments measured each period, which compares to approximately $992,000 in bond interest paid, partially offset by approximately $603,000 in charges for amortization of premiums paid and fair-value adjustments during the prior year.

 
Liquidity, capital resources and plan of operation
 
We have incurred losses since our inception and as of April 30, 2014December 31, 2017, we had an accumulated deficit of approximately $137$213 million. We will continue to incur losses until we generate sufficient revenue to offset our expenses, and we anticipate that we will continue to incur net losses for at least the next several years. We expect to incur increasedadditional expenses related to our development and potential commercialization of levosimendan Oxycytefor pulmonary hypertension and other potential indications, as well as identifying and developing other potential product candidates, and as a result, we will need to generate significant net product sales, royalty and other revenues to achieve profitability. As noted above, in April 2017, we announced that we would be exploring strategic alternatives in order to maximize stockholder value and that we had formed a strategic committee of three independent board members to supervise management in this review. We engaged Ladenburg Thalmann & Co. Inc., a subsidiary of Ladenburg Thalmann Financial Services Inc., as our financial advisor to assist in the strategic review process.
 
Liquidity
 
We have financed our operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. We had $58,966,033 and $1,842,251 total current assets of $8,062,893 and $13,628,175 and working capital (deficit) of $56,394,986$7,054,053 and $(67,326)$7,428,938 as of April 30, 2014December 31, 2017 and April 30, 2013,December 31, 2016, respectively. Our practice is to invest excess cash, where available, in short-term money market investment instruments.instruments and high quality corporate and government bonds.
 
Clinical and Preclinical Product Development
 
We are in the preclinical and clinical trial stagesstage in the development of our product candidates. We are currently initiatingrecently completed a Phase III3 clinical trial for levosimendan and we are conducting Phase II-b clinical trials for the use of Oxycyte in the treatment of severe traumatic brain injury.levosimendan. We expect our primary focus will be on initiating the Phase IIIadditional clinical trialsand preclinical studies for levosimendan and funding the continued testing of Oxycyte, since these products are the furthest along in the regulatory review process.for pulmonary hypertension or other potential indications. Our ability to continue to pursue testing and development of our products beyond April 30, 2017 maythe first quarter of calendar year 2019 will depend on obtaining license income or outside financial resources. There is no assurance that we will obtain any license agreement or outside financing or that we will otherwise succeed in obtaining any necessary resources.
 
Financings
 
On July 23, 2013, we sold 5,369 shares of Series C 8% convertible preferred stock and warrants for net proceeds of approximately $4.9 million. Additionally, on August 22, 2013 we issued 4,600 shares of Series D convertible preferred stock and warrants in exchange for $4.6 million of convertible notes that were scheduled to mature in June 2014.
On March 21, 2014, we sold 9,285,714 shares of common stock for net proceeds of approximately $55 million.
DuringWe did not complete any financings during the year ended April 30, 2014, we received approximately $7.1 million and issued 3,161,145 shares of common stock upon the exercise of our outstanding warrants.December 31, 2017 or 2016.

Operating Capital and Capital Expenditure Requirements
 
Our future capital requirements will depend on many factors that include, but are not limited to the following:
 
-
The
the initiation, progress, timing and completion of clinical trials for our product candidates and potential product candidates;
-
The
the outcome, timing and cost of regulatory approvals and the regulatory approval process;
-
Delays
delays that may be caused by changing regulatory requirements;
-
The
the number of product candidates that we pursue;
-
The
the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;
-
The
the timing and terms of future in-licensing and out-licensing transactions;collaboration, licensing, consulting or other arrangements that we may enter into;
-
The
the cost and timing of establishing sales, marketing, manufacturing and distribution capabilities;
-
The
the cost of procuring clinical and commercial supplies of our product candidates;
-
The
the extent to which we acquire or invest in businesses, products or technologies; and
-Thethe possible costs of litigation.
 
Based on our working capital at April 30, 2014December 31, 2017 we believe we have sufficient capital on hand to continue to fund operations through our fiscalthe first quarter of calendar year ending April 30, 2017.2019.
 
We will need substantial additional capital in the future in order to completecontinue the development and commercialization of levosimendan and Oxycyte, as well as to fund the development and commercialization of ourother future product candidates. Until we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. Such funding, if needed, may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses.
 
29

To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital.
 
Contractual Obligations
Contractual obligations represent future cash commitments and liabilities under agreements with third parties and exclude contingent contractual liabilities for which we cannot reasonably predict future payment, including contingencies related to potential future development, financing, contingent royalty payments and/or scientific, regulatory or commercial milestone payments under development agreements.

Summary of SignificantCritical Accounting Policies
 
Use of EstimatesThe preparation of the accompanying Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
 

Preclinical Study and Clinical Accruals—We estimate our preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and CROs that conduct and manage preclinical and clinical trials on our behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:
 
-
Fees
fees paid to CROs in connection with clinical trials,trials;
-
Fees
fees paid to research institutions in conjunction with preclinical research studies,studies; and
-
Fees
fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.
Revenue Recognition—Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.
Revenues from a cost-reimbursement grant sponsored by the United States Army, or Grant Revenue, are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.
Stock-Based CompensationEffective May 1, 2005, we adoptedWe account for stock-based awards to employees in accordance with Accounting Standards Codification, or ASC, 718 Compensation — Stock Compensation, usingwhich provides for the prospective transition method, which requires the measurement and recognitionuse of compensation expense for all stock-based payment awards granted, modified and settled to our employees and directors after May 1, 2005. Our Consolidated Financial Statements reflect the impact of ASC 718. We chose the “straight-line” attribution method for allocating compensation costs and recognized the fair value based method to determine compensation for all arrangements where shares of each stock optionor equity instruments are issued for compensation. Fair values of equity securities are determined by management based predominantly on a straight-line basisthe trading price of our common stock. The values of these awards are based upon their grant-date fair value. That cost is recognized over the requisiteperiod during which the employee is required to provide service period.in exchange for the reward.
 
We account for equity instruments issued to non-employees in accordance with ASC 505-50 Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest.
 
Impairment TestingIn accordance with GAAP, goodwill impairment testing is performed annually, or more frequently if indicated by events or conditions. In the course of the evaluation of the potential impairment of goodwill, either a qualitative or a quantitative assessment may be performed. If a qualitative evaluation determines that no impairment exists, then no further analysis is performed. If a qualitative evaluation is unable to determine whether impairment has occurred, a quantitative evaluation is performed. The quantitative impairment test first identifies potential impairments by comparing the fair value of the reporting unit with its carrying value. If the fair value exceeds the carrying amount, goodwill is not impaired. If the carrying value exceeds the fair value, the implied fair value of goodwill is calculated, and an impairment is recorded if the implied fair value is less than the carrying amount. The determination of goodwill impairment is highly subjective. It considers many factors both internal and external and is subject to significant changes from period to period.
During the year ended December 31, 2016, we recognized an impairment charge of $33.3 million related to our levosimendan product in Phase 3 clinical trial, which represents approximately $22 million for IPR&D assets and approximately $11.3 million for goodwill.
The LEVO-CTS trial was completed in December of 2016. Based on the data from the trial, levosimendan, given prophylactically prior to cardiac surgery to patients with reduced left ventricular function, had no effect on the co-primary outcomes. The study did not achieve statistically significant reductions in the dual endpoint of death or use of a mechanical assist device at 30 days, nor in the quad endpoint of death, myocardial infarction, need for dialysis, or use of a mechanical assist device at 30 days. Based on the results of the LEVO-CTS trial and subsequent FDA feedback we do not anticipate additional development of levosimendan for the treatment of LCOS in patients undergoing cardiac surgery. As of December 31, 2016, management determined the IPR&D asset, and corresponding Goodwill, was more than temporarily impaired.
Fair market value accounting (derivative warrant liability)A significant estimate that could have a material effect on net (loss) gain is the fair market value accounting for our derivative liability. Our derivative liability consists of free standing warrants that are recorded as liabilities due to the price protection anti-dilution provisions in the event of a subsequent equity sale. As a result, the warrants must be recorded as a liability at fair value. The changes in fair value are posted in other (income) expense. We utilize the Monte Carlo method to estimate the fair value of our warrants. The three most significant factors in the Monte Carlo method are (i) our stock price, (ii) the volatility of our stock price and (iii) the remaining term of the warrants. During the year ending December 31, 2017, a $0.80 decrease in the value of our stock was the primary cause of the $192,419 derivative gain.

Recent Accounting Pronouncements
 
In June 2014,July 2017, the Financial Accounting Standards Board, or the FASB, issued an accounting standard that changes the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The standard will be effective on January 1, 2019. Early adoption is permitted, including adoption in an interim period. We do not believe adoption of this standard will have a material impact on our consolidated financial statements and related disclosures.
In January 2017, the FASB issued Accounting Standards Update (“ASU”) 2014-10, Development Stage Entities (Topic 915).an accounting standard that provides guidance for evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The objectiveguidance provides a screen to determine when an integrated set of assets and activities, or a set, does not qualify to be a business. The screen requires that when substantially all of the amendmentsfair value of the gross assets acquired (or disposed of) is concentrated in an identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the guidance requires a set to be considered a business to include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs and removes the evaluation as to whether a market participant could replace the missing elements. The standard became effective on January 1, 2018 and was adopted on a prospective basis. We do not believe adoption of this update is to improve financial reporting by reducing the cost and complexity associated with the incremental reporting requirements for development stage entities. Users ofstandard will have a material impact on our consolidated financial statements of development stage entities toldand related disclosures.
In August 2016, the BoardFASB issued an accounting standard that the development stage entity distinction, the inception-to-date information,clarifies how companies present and classify certain other disclosures currently required under U.S. GAAPcash receipts and cash payments in the statement of cash flows where diversity in practice exists. The standard is effective in our first quarter of fiscal 2018. We do not believe that adopting this updated standard will have a material impact on our consolidated financial statements of development stage entities provide informationand related disclosures.
In June 2016, the FASB issued an accounting standard that has limited relevanceamends how credit losses are measured and is generallyreported for certain financial instruments that are not decision useful. Asaccounted for at fair value through net income. This standard will require that credit losses be presented as an allowance rather than as a result, the amendments in this update remove all incremental financial reporting requirements from US GAAPwrite-down for development stage entities, thereby improving financial reporting by eliminating the costavailable-for-sale debt securities and complexity associated with providing that information. The amendments arewill be effective for interim and annual reporting periods beginning after December 15, 2014, and interimJanuary 1, 2020, with early adoption permitted, but not earlier than annual reporting periods beginning after December 15, 2015. Early adoptionJanuary 1, 2019. A modified retrospective approach is permitted. The Company has elected to early adoptbe used for certain parts of this guidance, and therefore is no longer presentingwhile other parts of the guidance are to be applied using a prospective approach.

In May 2014, the FASB issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers (ASU 2014-09) providing a comprehensive newan accounting standard that supersedes nearly all existing revenue recognition standard. ASU 2014-09guidance under GAAP. The standard is principles-based and provides revised standardsa five-step model to determine when and how revenue is recognized. The core principle of recognition predicated onthe standard is that revenue should be recognized when an entitya company transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expectswe expect to be entitled in exchange for those goods or services. ASU 2014-09In March 2016, the FASB issued a standard to clarify the implementation guidance on principal versus agent considerations, and in April 2016, the FASB issued a standard to clarify the implementation guidance on identifying performance obligations and licensing. The standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017. Early application prior to the original effective date was not permitted. The standard permits the use of either the retrospective or cumulative effect transition method.
We reviewed our current accounting policies and practices to assess the impact of the guidance on our business processes. Based on this evaluation, the adoption of this standard will not have a material impact on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued an accounting standard intended to improve financial reporting regarding leasing transactions. The standard will require us to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The standard will also require us to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 months. The standard is effective for us in our first quarter of fiscal 2018. ASU 2014-09 can be applied retrospectively with a modified retrospective applicationfinancial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. We are currently evaluating the impact of our pending adoption of ASU 2014-09that this standard will have on our consolidated financial statements.statements and related disclosures.
 
In July 2013,January 2016, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 requires entities to present in the consolidatedaccounting standard that will enhance our reporting for financial instruments. The standard is effective for financial statements an unrecognized tax benefit, or a portion of an unrecognized tax benefit as a reduction to a deferred tax assetissued for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward except to the extent such items are not available or not intended to be used at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position. In such instances, the unrecognized tax benefit is required to be presented in the consolidated financial statements as a liability and not be combined with deferred tax assets. This guidance is effective prospectively for fiscal years,annual periods beginning after December 15, 2017, and interim periods within those years,annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning after December 15, 2013. Theof the fiscal year of adoption.

TENAX THERAPEUTICS, INC.
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
As of April 30, 2014 and 2013, and for the years then ended.
 
NOTE A—DESCRIPTION OF BUSINESS
 
Description of Business—Oxygen BiotherapeuticsTenax Therapeutics (the “Company”) was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David & Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. On June 17, 2008, the stockholders of Synthetic Blood International approved the Agreement and Plan of Merger dated April 28, 2008, between Synthetic Blood International and Oxygen Biotherapeutics, Inc., a Delaware corporation. Oxygen Biotherapeutics was formed on April 17, 2008, by Synthetic Blood International to participate in the merger for the purpose of changing the state of domicile of Synthetic Blood International from New Jersey to Delaware. Certificates of Merger were filed with the states of New Jersey and Delaware, and the merger was effective June 30, 2008. Under the Plan of Merger, Oxygen Biotherapeutics iswas the surviving corporation and each share of Synthetic Blood International common stock outstanding on June 30, 2008 was converted to one share of Oxygen Biotherapeutics common stock. On September 19, 2014, the Company changed its name to Tenax Therapeutics, Inc.
 
On October 18, 2013, the Company created a wholly owned subsidiary, Life Newco, Inc., a Delaware corporation (“Life Newco”), to acquire certain assets of Phyxius Pharma, Inc., a Delaware corporation (“Phyxius”), pursuant to an Asset Purchase Agreement, dated October 21, 2013 (the “Asset Purchase Agreement”), by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius (the “Phyxius Stockholders”). As further discussed in Note D below, onOn November 13, 2013, under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired certain assets, including a license granting Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan,levosimendan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada.
 
Reverse Stock Split
 
The Company initiated a 1-for-20 reverse stock split effective May 10, 2013.February 23, 2018 at 5:00 p.m. All shares and per share amounts in these Consolidated Financial Statements and notes thereto have been retroactively adjusted to give effect to the reverse stock split.
 
Going Concern
Management believes the accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which contemplate continuation of the Company as a going concern. The Company has an accumulated deficit of $213,499,285 and $204,659,603 at December 31, 2017 and 2016, respectively, and used cash in operations of $12,140,517 and $15,871,300 during the years ended December 31, 2017 and 2016, respectively. The Company requires substantial additional funds to complete clinical trials and pursue regulatory approvals. Management is actively seeking additional sources of equity and/or debt financing; however, there is no assurance that any additional funding will be available.
In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the accompanying December 31, 2017 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. These factors, among others, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.
NOTE B—SUMMARY OF SIGNIFICANTCRITICAL ACCOUNTING POLICIES
 
Use of Estimates
 
The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
 
On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted.
 
Principles of Consolidation
 
The accompanying consolidated financial statements include the accounts and transactions of Oxygen Biotherapeutics,Tenax Therapeutics, Inc. and Life Newco, Inc. All material intercompany transactions and balances have been eliminated in consolidation.consolidation.
 
Goodwill
 
Acquired businesses are accounted for using the acquisition method of accounting, which requires that assets acquired, including identifiable intangible assets, and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. If the acquired net assets do not constitute a business, the transaction is accounted for as an asset acquisition and no goodwill is recognized.

TENAX THERAPEUTICS, INC.
 
Goodwill is reviewed for impairment on an annual basis or more frequently if events or circumstances indicate potential impairment. The Company’s goodwill evaluation is based on both qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company assesses qualitative factors to determine if its sole reporting unit’s fair value is more likely than not to exceed its carrying value, including goodwill. In the event the Company determines that it is more likely than not that its reporting unit’s fair value is less than its carrying amount, quantitative testing is performed comparing recorded values to estimated fair values. If the fair value exceeds the carrying value, goodwill is not impaired. If the carrying value exceeds the fair value, an impairment charge is recognized through a charge to operations based upon the excess of the carrying value of goodwill over the implied fair value.  There
During the year ended December 31, 2016, the Company recognized an impairment charge of $33.3 million related to our levosimendan product in Phase 3 clinical trial, which represents approximately $22 million for in-process research and development (“IPR&D”) assets and approximately $11.3 million for goodwill.
The LEVO-CTS trial was completed in December of 2016. Based on the data from the trial, levosimendan, given prophylactically prior to cardiac surgery to patients with reduced left ventricular function, had no impairment toeffect on the co-primary outcomes. The study did not achieve statistically significant reductions in the dual endpoint of death or use of a mechanical assist device at 30 days, nor in the quad endpoint of death, myocardial infarction, need for dialysis, or use of a mechanical assist device at 30 days. Based on the results of the LEVO-CTS trial and subsequent U.S. Food and Drug Administration (“FDA”) feedback, the Company does not anticipate additional development of levosimendan for the treatment of low cardiac output syndrome (“LCOS”) in patients undergoing cardiac surgery. As of December 31, 2016, management determined the IPR&D asset, and corresponding goodwill, recognized during 2014.was more than temporarily impaired.
 
Cash and Cash Equivalents
 
The Company considers all highly liquid instruments with a maturity date of three months or less, when acquired, to be cash equivalents.
 
Cash Concentration Risk
 
On July 21, 2010, the Wall Street Reform and Consumer Protection Act permanently increased the FDICFederal Deposit Insurance Corporation (the “FDIC”) insurance limits to $250,000 per depositor per insured bank. At April 30, 2014, theThe Company had $58,038,597cash balances of cash balances$849,851 and $9,362,812 uninsured by the FDIC.FDIC as of December 31, 2017 and 2016, respectively.
 
Liquidity and Capital Resources
 
We haveThe Company has financed ourits operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. WeThe Company had $58,966,033 and $1,842,251 total current assets of $8,062,893 and $13,628,175 and working capital (deficit) of $56,394,986$7,054,053 and $(67,326)$7,428,937 as of April 30, 2014December 31, 2017 and April 30, 2013,2016, respectively. Our practice is to invest excess cash, where available, in short-term money market investment instruments.
 
Cash resources, including the fair value of the Company’s available for sale marketable securities as of April 30, 2014December 31, 2017 were approximately $58.3$9.5 million, compared to approximately $784,000$21.9 million as of April 30, 2013.December 31, 2016.
The Company expects to continue to incur expenses related to development of levosimendan for pulmonary hypertension and other potential indications, as well as identifying and developing other potential product candidates. Based on its resources at April 30, 2014, and the current plan of expenditure on continuing development of the Company’s current product candidates,December 31, 2017, the Company believes that it has sufficient capital to fund its planned operations through the fiscalfirst quarter of calendar year ending April 30, 2017.2019. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot assure that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs.
 
To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates or grant licenses on terms that may not be favorable to the Company. Any or all of the foregoing may have a material adverse effect on the Company’s business and financial performance.
 

39
Deferred financing costs
 
Deferred financing costs represent legal, due diligence and other direct costs incurred to raise capital or obtain debt. Direct costs include only “out-of-pocket” or incremental costs directly related to the effort, such as a finder’s fee and accounting and legal fees. These costs will be capitalized if the efforts are successful or expensed when unsuccessful. Indirect costs are expensed as incurred. Deferred financing costs related to debt are amortized over the life of the debt. Deferred financing costs related to issuing equity are charged to Additional Paid-in Capital.
 
Derivative financial instruments
 
The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible promissory note instruments and other convertible equity instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under FASB ASC 815, Derivatives and Hedging (“ASC 815”) to be accounted for separately from the host contract and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.
 
Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments and are evaluated and accounted for in accordance with the provisions of ASC 815. Pursuant to ASC 815, an evaluation of specifically identified conditions is made to determine whether the fair value of warrants issued is required to be classified as equity or as a derivative liability.
 
39

Beneficial conversion and warrant valuation
In accordance with FASB ASC 470-20, Debt with Conversion and Other Options, the Company records a beneficial conversion feature (“BCF”) related to the issuance of convertible debt that have conversion features at fixed rates that are in-the-money when issued and the fair value of warrants issued in connection with those instruments. The BCF for the convertible instruments is recognized and measured by allocating a portion of the proceeds to warrants, based on their relative fair value, and as a reduction to the carrying amount of the convertible debt equal to the intrinsic value of the conversion feature. As described in Note F, the discount recorded in connection with the BCF and warrant valuation is recognized as non-cash interest expense and is amortized over the life of the convertible note.
Preclinical Study and Clinical Accruals
 
The Company estimates its preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations (“CROs”) that conduct and manage preclinical and clinical trials on its behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:
 
-
Fees
fees paid to CROs in connection with clinical trials,

-
Fees
fees paid to research institutions in conjunction with preclinical research studies, and
-
Fees
fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.
Property and Equipment, Net
 
Property and equipment are stated at cost, subject to adjustments for impairment, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives:
 
Laboratory equipment3 – 5 years
Office equipment5 years
Office furniture and fixtures7 years
Computer equipment and software3 years
Leasehold improvementsShorter of useful life or remaining lease term
 
Maintenance and repairs are charged to expense as incurred, improvements to leased facilities and equipment are capitalized.
 
Impairment of Long-Lived Assets
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Revenue Recognition
Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.  The Company's practice is to accept product returns from retailers only if properly requested, authorized and approved.  As a percentage of gross sales, returns were less than 5% in fiscal years 2014 and 2013.
40

Revenues from a cost-reimbursement grant sponsored by the United States Army, or Grant Revenue, are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.
Research and Development Costs
 
Research and development costs include, but are not limited to, (i) expenses incurred under agreements with contract research organizationsCROs and investigative sites, which conduct our clinical trials and a substantial portion of our preclinical studies; (ii) the cost of manufacturing and supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, and equipment, and laboratory and other supplies. All research and development expenses are expensed as incurred.

 
Income Taxes
 
Deferred tax assets and liabilities are recorded for differences between the financial statement and tax bases of the assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is recorded for the amount of income tax payable or refundable for the period increased or decreased by the change in deferred tax assets and liabilities during the period.
 
Stock-Based Compensation
 
The Company accounts for stock based compensation in accordance with ASC 718 Compensation — Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based payment awards granted, modified and settled to our employees and directors. The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option on a straight-line basis over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.
 
Loss Per Share
 
Basic loss per share, which excludes antidilutive securities, is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding for that particular period. In contrast, diluted loss per share considers the potential dilution that could occur from other equity instruments that would increase the total number of outstanding shares of common stock. Such amounts include shares potentially issuable under outstanding options, warrantsrestricted stock and convertible debentures. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share follows.warrants.

Operating Leases
 
The Company maintains operating leases for its office and laboratory facilities. The lease agreements may include rent escalation clauses and tenant improvement allowances. The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the company takes possession of the leased space. Differences between rental expense and actual rental payments are recorded as deferred rent liabilities and are included in “Other liabilities” on the consolidated balance sheets.
Recent Accounting Pronouncements
In July 2017, the Financial Accounting Standards Board (the “FASB”), issued an accounting standard that changes the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The standard will be effective on January 1, 2019. Early adoption is permitted, including adoption in an interim period. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.
 

In January 2017, the FASB issued an accounting standard that provides guidance for evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance provides a screen to determine when an integrated set of assets and activities, or a set, does not qualify to be a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in an identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the guidance requires a set to be considered a business to include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs and removes the evaluation as to whether a market participant could replace the missing elements. The standard became effective on January 1, 2018 and was adopted on a prospective basis. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.
In August 2016, the FASB issued an accounting standard that clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows where diversity in practice exists. The standard is effective in the Company’s first quarter of fiscal 2018. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.
In June 2016, the FASB issued an accounting standard that amends how credit losses are measured and reported for certain financial instruments that are not accounted for at fair value through net income. This standard will require that credit losses be presented as an allowance rather than as a write-down for available-for-sale debt securities and will be effective for interim and annual reporting periods beginning January 1, 2020, with early adoption permitted, but not earlier than annual reporting periods beginning January 1, 2019. A modified retrospective approach is to be used for certain parts of this guidance, while other parts of the guidance are to be applied using a prospective approach. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.
In May 2014, the FASB issued an accounting standard that supersedes nearly all existing revenue recognition guidance under GAAP. The standard is principles-based and provides a five-step model to determine when and how revenue is recognized. The core principle of the standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued a standard to clarify the implementation guidance on principal versus agent considerations, and in April 2016, the FASB issued a standard to clarify the implementation guidance on identifying performance obligations and licensing. The standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017. Early application prior to the original effective date was not permitted. The standard permits the use of either the retrospective or cumulative effect transition method.
The Company reviewed its current accounting policies and practices to assess the impact of the guidance on its business processes. Based on this evaluation, the adoption of this standard will not have a material impact on its consolidated financial statements and related disclosures.
In February 2016, the FASB issued an accounting standard intended to improve financial reporting regarding leasing transactions. The standard will require the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The standard will also require it to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 months. The standard is effective for financial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements and related disclosures.
In January 2016, the FASB issued an accounting standard that will enhance the Company’s reporting for financial instruments. The standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning of the fiscal year of adoption. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.

Fair Value
 
The Company recordsdetermines the fair value of its financial assets and liabilities in accordance with ASCthe FASB Accounting Standards Codification (“ASC”) 820 Fair Value Measurements. The Company's consolidatedCompany’s balance sheet includes the following financial instruments: cash and cash equivalents, short-term notes payable, convertible preferred stockinvestments in marketable securities and convertible notes.warrant liabilities. The Company considers the carrying amount of its cash and cash equivalents and short-term notes payable to approximate fair value due to the short-term nature of these instruments. The Company did not elect the fair value option and records the carrying value of its convertible notes at amortized cost in accordance with ASC 470-20.
 
Accounting for fair value measurements involves a single definition of fair value, along with a conceptual framework to measure fair value, with a fair value defined as "the“the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." The fair value measurement hierarchy consists of three levels:
 
Level one
Quoted market prices in active markets for identical assets or liabilities;
Level two
Inputs other than level one inputs that are either directly or indirectly observable,observable; and
Level three
Unobservable inputs developed using estimates and assumptions; which are developed by the reporting entity and reflect those assumptions that a market participant would use.
42

The Company applies valuation techniques that (1) place greater reliance on observable inputs and less reliance on unobservable inputs and (2) are consistent with the market approach, the income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company’s consolidated financial statements.
Investments in Marketable Securities
The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income (expense) in the Consolidated Financial Statements.Statements of Operations and Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis.
The Company recognized a gain of $422 and a loss $41,955 for the years ended December 31, 2017 and 2016, respectively.
Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At December 31, 2017, the Company believes that the costs of its investments are recoverable in all material respects.
The following tables summarize the fair value of the Company’s investments by type. The estimated fair value of the Company’s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These fair values are obtained from independent pricing services which utilize Level 2 inputs:

Warrant liability
 
On July 23, 2013, the Company issued common stock warrants in connection with the issuance of Series C 8% Preferred Stock (the “Series C Warrants”). As part of the offering, the Company issued 137,668 warrants at an exercise price of $52.00 per share and contractual term of 6 years. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,380,883, which represents the fair market value of the warrants at that date. The following tables show information regarding assets and liabilities measured atinitial fair value on a recurring basisrecorded as warrants within stockholders’ equity of April 30, 2014$233,036 was reversed and 2013:

Financial assets or liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable.
As further discussed in Note G below, on July 23, 2013, the Company issued common stock warrants (the “Series C Warrants”) in connection with the issuance of Series C 8% Convertible Preferred Stock (the “Series C Stock”). The Series C warrantsWarrants are measured using the Monte Carlo valuation model which is based, in part, upon inputs for which there is little or no observable market data, requiring the Company to develop its own assumptions.  The assumptions used in calculating the estimated fair value of the warrants represent the Company’s best estimates; however, these estimates involve inherent uncertainties and the application of management judgment.  As a result, if factors change and different assumptions are used, the warrant liabilities and the change in estimated fair value of the warrants could be materially different.
 
Inherent in the Monte Carlo valuation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.  The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.  The expected life of the warrants is assumed to be equivalent to their remaining contractual term.  The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.
 
43

The Monte Carlo model is used for the Series C warrantsWarrants to appropriately value the potential future exercise price adjustments triggered by the anti-dilution provisions. This requires Level 3 inputs which are based on the Company’s estimates of the probability and timing of potential future financings and fundamental transactions.  The other assumptions used by the Company are summarized in the following table for the Series C warrantsWarrants that were outstanding as of April 30, 2014; noDecember 31, 2017 and December 31, 2016:

In June 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-10, Development Stage Entities (Topic 915). The objective of the amendments in this update is to improve financial reporting by reducing the cost and complexity associated with the incremental reporting requirements for development stage entities. Users of financial statements of development stage entities told the Board that the development stage entity distinction, the inception-to-date information, and certain other disclosures currently required under U.S. GAAP in the financial statements of development stage entities provide information that has limited relevance and is generally not decision useful. As a result, the amendments in this update remove all incremental financial reporting requirements from US GAAP for development stage entities, thereby improving financial reporting by eliminating the cost and complexity associated with providing that information. The amendments are effective for annual reporting periods beginning after December 15, 2014, and interim reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company has elected to early adopt this guidance, and therefore is no longer presenting the financial statements in accordance with ASU 915, with inception to date disclosures.

In May 2014,There were no significant transfers between levels during the FASB issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers (ASU 2014-09) providing a comprehensive new revenue recognition standard. ASU 2014-09 provides revised standards of recognition predicated on when an entity transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for us in our first quarter of fiscal 2018. ASU 2014-09 can be applied retrospectively with a modified retrospective application permitted. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.year ended December 31, 2017.
 
In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 requires entities to present in the consolidated financial statements an unrecognized tax benefit, or a portion of an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward except to the extent such items are not available or not intended to be used at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position. In such instances, the unrecognized tax benefit is required to be presented in the consolidated financial statements as a liability and not be combined with deferred tax assets. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 did not have a material impact on the Company’s consolidated financial statements.
NOTE C—BALANCE SHEET COMPONENTS
 
Inventory
The Company operates in an industry characterized by rapid improvements and changes to its technology and products. The introduction of new products by the Company or its competitors can result in its inventory being rendered obsolete or requiring it to sell items at a discount. The Company evaluates the recoverability of its inventory by reference to its internal estimates of future demands and product life cycles. As of April 30, 2014, due to development delays by the Company’s licensee, the Company does not believe the existing inventory will be sold prior to the expiration of its stability life and has recorded a charge of approximately $97,000 to cost of sales for the year ended April 30, 2014 equal to the carrying value of cosmetics inventory. The Company's future estimates are subjective and actual results may vary.

NOTE D—ACQUISITION
On November 13, 2013, the Company, through its wholly owned subsidiary, Life Newco, acquired certain assets of Phyxius pursuant to the Asset Purchase Agreement. The acquisition was accounted for under the acquisition method of accounting for business combinations in accordance with FASB ASC 805,  Business Combinations, which requires, among other things that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date.  Acquisition-related costs are not included as a component of the acquisition accounting, but are recognized as expenses in the periods in which the costs are incurred.  Any changes within the measurement period resulting from facts and circumstances that existed as of the acquisition date may result in retrospective adjustments to the provisional amounts recorded at the acquisition date.
Under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired (the “Acquisition”) certain assets, including that certain License Agreement (the “License”), dated September 20, 2013 by and between Phyxius and Orion Corporation, a global healthcare company incorporated under the laws of Finland (“Orion”), and that certain Side Letter, dated October 15, 2013 by and between Phyxius and Orion.  The License grants Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial (the “Product”) in the United States and Canada (the “Territory”).  Pursuant to the License, Life Newco must use Orion’s “Simdax®” trademark to commercialize the Product.  The License also grants to Life Newco a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication.  Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights.  Additionally, Life Newco must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by Life Newco under the License.  The License has a fifteen (15) year term, provided, however, that the License will continue after the end of the fifteen year term in each country in the Territory until the expiration of Orion’s patent rights in the Product in such country (the “Term”).  Orion may terminate the License if the human clinical trial using the Product and studying reduction in morbidity and mortality of cardiac surgery patients at risk of low cardiac output syndrome (LCOS) as described in the US Food and Drug Administration (the “FDA”) agreed upon clinical study protocol (the “Study”) is not started by July 31, 2014. As of July 24, 2014 the Company is in negotiations with multiple clinical sites.
The following table summarizes the consideration transferred to acquire Phyxius and the amounts of identified assets acquired and liabilities assumed at the acquisition date.
Fair Value of Consideration Transferred:
Common stock8,747,802
Series E convertible preferred stock15,299,198
   Total24,047,000
The Company issued 1,366,844 shares of its common stock that had a total fair value of approximately $8.7 million based on the closing market price on November 13, 2013, the acquisition date. The Company also issued 32,992 shares of its Series E Convertible Preferred Stock (the “Series E Stock”), which are convertible into an aggregate of 3,299,200 shares of common stock that had a total fair value of approximately $15.3 million.
46

The rights, preferences and privileges of the Series E Stock are set forth in the Certificate of Designation of Series E Convertible Preferred Stock that the Company filed with the Secretary of State of the State of Delaware on November 13, 2013.  Each share of Series E Stock automatically converted into 100 shares of common stock following receipt of stockholder approval for the transaction at the special meeting of stockholders held on March 13, 2014.  Approximately 11% of the shares of converted common stock vested immediately upon receipt of stockholder approval for the transaction, while the remainder vested upon the closing of the Company’s underwritten offering of 9,285,714 shares of common stock on March 21, 2014, which resulted in net proceeds of approximately $55 million.  
The Series E Stock was convertible into restricted common shares using a 100-for-one ratio at any time and in accordance with a vesting schedule contingent upon achievement of Company-specific non-financial conditions. As a result, the fair value of the Preferred Shares was inferred based on their common stock equivalent value given the conversion terms. The conditional vesting of the Series E Stock was accounted for by subtracting the fair value of an equal number of put options that would effectively protect the common stock equivalent stock value as of the closing date. The terms of the put options were as follows:
-  Exercise price equal to the common stock price as of the Valuation Date.
-  Term based on management’s risk-adjusted expected time to meeting the vesting condition, which was further increased by 6 months to reflect the marketability restriction of the unregistered stock, consistent with SEC Rule 144 of the Securities Act.
-  Volatility was consistent with the term for the individual milestone payments derived from the median historical asset volatility for a set of comparable guideline companies. The volatility was then relevered to estimate the equity volatility of the Company.
In accordance with the provisions of FASB ASC 805, the following table presents the preliminary allocation of the total fair value of consideration transferred, as discussed above, to the acquired tangible and intangible assets and assumed liabilities of Phyxius based on their estimated fair values as of the closing date of the transaction, measurement period adjustments recorded since the acquisition date and the adjusted allocation of the total fair value:

(1)The measurement period adjustments primarily reflect the recording of a deferred tax liability and resulting goodwill.  The measurement period adjustments were made to reflect facts and circumstances existing as of the acquisition date and did not result from intervening events subsequent to the acquisition date.
47

The fair value of the acquired in-process research and development, (“IPR&D”), intangible asset of approximately $22.0 million was determined using the multi-period excess earnings method. The Company did not acquire any other class of assets as a result of the acquisition.
Pursuant to the terms of the License, the Company paid to Orion a non-refundable up-front payment in the amount of $1 million.
The License also includes the following development milestones for which the Company shall make non-refundable payments to Orion no later than twenty-eight (28) days after the occurrence of the applicable milestone event: (i) $2.0 million upon the grant of FDA approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (ii) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory. The Company must also pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the Term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as the Company sells the Product in the Territory.
In connection with the closing of the Acquisition, Phyxius’ co-founder, Chief Executive Officer and stockholder, John Kelley, became the Company’s Chief Executive Officer and two other Phyxius employees and stockholders, Doug Randall and Douglas Hay, PhD became employees of the Company as Vice President, Business and Commercial Operations and Vice President, Regulatory Affairs, respectively.  Michael Jebsen, the Company’s prior Interim Chief Executive Officer and current Chief Financial Officer, continued serving as the Company’s Chief Financial Officer.  In addition, Mr. Kelley was subsequently appointed to the Company’s Board of Directors, and Gerald T. Proehl, a designee of the Phyxius Stockholders, was appointed to the Board of Directors on April 3, 2014 following receipt of stockholder approval for the transaction.  Pursuant to the Asset Purchase Agreement, the Company agreed to propose that its stockholders approve an amendment to the Company’s 1999 Stock Plan to increase the amount of stock options authorized for issuance under the 1999 Stock Plan to not less than 4,000,000 shares of common stock. On March 13, 2014, the Company received stockholder approval to increase the option plan.

The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.
 
The Company used the following assumptions to estimate the fair value of options granted under its stock option plans for the years ended April 30, 2014December 31, 2017 and 2013:
  For the year ended April 30

Expected dividend yield
  0.00%
  0.00%
Risk-Free Interest Rate
The risk-free interest rate assumption was based on U.S. Treasury instruments with a term that is consistent with the expected term of the Company’s stock options.
Expected Volatility
The expected stock price volatility for the Company’s common stock was determined by examining the historical volatility and trading history for its common stock over a term consistent with the expected term of its options.
Expected Term
The expected term of stock options represents the weighted average period the stock options are expected to remain outstanding. It was calculated based on the historical experience that the Company has had with its stock option grants.
Expected Dividend Yield
The expected dividend yield of 0% is based on the Company’s history and expectation of dividend payouts. The Company has not paid and do not anticipate paying any dividends in the near future.
Forfeitures
As stock-based compensation expense recognized in the statement of operations for the years ended April 30, 2014December 31, 2017 and 20132016 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on the Company’s historical experience.
 

The weighted-average grant-date fair value of options granted during the yearsyear ended April 30, 2014 and 2013December 31, 2017 was $5.64 and $32.60, respectively

The Company has established a valuation allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates the recoverability of the deferred tax assets. At such time that it is determined that it is more likely than not that deferred tax assets will be realizable, the valuation allowance will be reduced. The net decrease in the valuation allowance during 2017 was approximately $14.3 million.
 

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law, which reduced the federal corporate income tax rate to 21% for tax years beginning after December 31, 2017. As a result of the newly enacted tax rate, the Company adjusted its deferred tax assets as of December 31, 2017, by applying the new 21% rate, which resulted in a decrease to the net deferred tax asset of approximately $17.5 million.
The SEC staff issued SAB 118 which will allow the Company to record provisional amounts related to accounting for the Tax Act during a measurement period which is similar to the measurement period used when accounting for business combinations. The Company is following the guidance set forth by SAB 118 and any amounts calculated are provisional estimates and will be reevaluated as more information or guidance becomes available. The Company will continue to assess the impact of the recently enacted Tax Act on its business and consolidated financial statements.
As of April 30, 2014,December 31, 2017, the Company had Federalfederal and Statestate net operating loss carryforwards of approximately $82.8$132.2 million and $65.9$105.6 million available to offset future federal and state taxable income, respectively. The federal net operating loss carryforwards began to expire in 2012 and the state net operating loss carryforwards begin to expire in 2023 respectively2018 and valuation allowances have been provided.
 
Utilization of the net operating loss carryforwards may be subject to an annual limitation due to the ownership percentage change limitations provided by the Internal Revenue Code of 1986 and similar state provisions. The annual limitations may result in the expiration of the net operating losses before utilization.
 
Management has evaluated all other tax positions that could have a significant effect on the Consolidated Financial Statementsfinancial statements and determined the Company had no uncertain income tax positions at April 30, 2014.December 31, 2017.
 
The Company files U.S. and state income tax returns with varying statutes of limitations. The tax years 19992001 and forward remain open to examination due to the carryover of unused net operating losses or tax credits.

Disclosure Controls and Procedures
 
Our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in rules and forms adopted by the Securities and Exchange Commission, or SEC, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures.
 
Management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Form 10-K. Based on such evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of April 30, 2014,December 31, 2017, our disclosure controls and procedures were effective at the reasonable assurance level.
 
Changes in Internal Controls over Financial Reporting
 
From time to time, we may review and make changes to our internal control over financial reporting that are intended to enhance the effectiveness of our internal control over financial reporting and which do not have a material effect on our overall internal control over financial reporting. During the three months ended April 30, 2014,December 31, 2017, we made no changes to our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that we believe materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 
Management’s Annual Report on Internal Control over Financial Reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting, as defined in rules promulgated under the Exchange Act, is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and affected by our Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Consolidated Financial Statements for external purposes in accordance with GAAP. Internal control over financial reporting includes those policies and procedures that:
 
-
Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;
-
-
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of Consolidated Financial Statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and our Board of Directors; and
-
-
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our Consolidated Financial Statements.
Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also can be circumvented by collusion or improper override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process, and it is possible to design into the process safeguards to reduce, though not eliminate, this risk.
 
65

Our management assessed the effectiveness of our internal control over financial reporting as of April 30, 2014.December 31, 2017. In making its assessment, management used the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO.COSO, in its 2013 Internal Control — Integrated Framework. Based on its assessment, management has concluded that our internal control over financial reporting was effective as of April 30, 2014.
