Organization and Business
Organization and Business	1. Organization and Business Jaguar Health, Inc. (“Jaguar” or the “Company”) was founded in San Francisco, California as a Delaware corporation on June 6, 2013 (inception). The Company was a majority-owned subsidiary of Napo until the close of the Company's initial public offering on May 18, 2015. The Company was formed to develop and commercialize first-in-class prescription and non-prescription products for companion and production animals and horses. The Company's first non-prescription commercial products, Neonorm Calf and Neonorm Foal, were launched in 2014 and 2016, respectively. On July 31, 2017, Jaguar completed a merger with Napo pursuant to the Agreement and Plan of Merger dated March 31, 2017, by and among Jaguar, Napo, Napo Acquisition Corporation (“Merger Sub”), and Napo's representative (the “Merger Agreement”). In accordance with the terms of the Merger Agreement, upon the completion of the merger, Merger Sub merged with and into Napo, with Napo surviving as the wholly owned subsidiary (the “Merger” or “Napo Merger”). Immediately following the Merger, Jaguar changed its name from “Jaguar Animal Health, Inc.” to “Jaguar Health, Inc.” Napo now operates as a wholly owned subsidiary of Jaguar focused on human health including the ongoing development of crofelemer and commercialization of Mytesi. On March 15, 2021, Jaguar established Napo EU S.p.A (which changed its name in December 2021 to “Napo Therapeutics”) based in Milan, Italy as a subsidiary of Napo. Napo Therapeutics’ core mission is to provide access to crofelemer in Europe to address significant rare/orphan disease indications, including, initially, two key orphan target indications: Short bowel syndrome (SBS) with intestinal failure, and congenital diarrheal disorders (CDD). On December 13, 2021, the European Medicines Agency (EMA) granted orphan-drug designation (ODD) for crofelemer for the short bowel syndrome (SBS) indication in the European Union following review of the ODD application Napo submitted to the EMA in September 2021. Following this decision from the EMA, Napo Therapeutics is initiating efforts to commence clinical development of crofelemer in both adult and pediatric SBS patients in support of the company’s key focus on leveraging the EMA’s accelerated conditional marketing authorization pathway in Europe for this rare disease. Napo Therapeutics has also agreed to support investigator-initiated trials (IITs), which are expected to provide proof of concept (POC) support for potential expanded access programs for crofelemer for patients with CDD and/or SBS patients with intestinal failure. The expanded access program will be initiated following completion of these studies and upon publication of POC results, potentially in 2023. Crofelemer previously received ODD in the U.S. from the FDA for SBS. SBS affects approximately 10,000 to 20,000 people in the U.S., according to the Crohn's & Colitis Foundation, and it is estimated that the population of SBS patients in Europe is approximately the same size. Despite limited treatment options, the global SBS market exceeded $568 million in 2019 and is expected to reach $4.6 billion by 2027, according to a report by Vision Research Reports. Most of the activities of the Company are focused on the commercialization of Mytesi and Canalevia-CA1 and the ongoing clinical development of crofelemer for the prophylaxis of diarrhea in adult patients receiving targeted cancer therapy (CTD). Napo’s pivotal OnTarget Phase 3 clinical trial of crofelemer for prophylaxis of CTD was initiated in October 2020 and is ongoing. In the field of animal health, we are continuing limited activities related to developing and commercializing first-in-class gastrointestinal products for dogs, dairy calves and foals. Crofelemer is a novel, first in class anti secretory agent which has a normalizing effect on electrolyte and fluid balance while acting locally in the gut, and this mechanism of action has the potential to benefit multiple disorders that cause gastrointestinal distress, including diarrhea and abdominal discomfort. Crofelemer is in development for multiple possible follow-on indications in addition to prophylaxis for cancer therapy related diarrhea (CTD), including rare disease indications for symptomatic treatment of infants and children with congenital diarrheal disorders (“CDD”) and for adult and pediatric patients with short bowel syndrome (SBS) with intestinal failure. As stated above, crofelemer has received orphan drug designation (ODD) for short bowel syndrome (SBS) in the EU, and crofelemer has also received ODD in the US for SBS. Furthermore, the drug is being evaluated for management of diarrhea and abdominal discomfort in inflammatory bowel disease (IBD); diarrhea-predominant irritable bowel syndrome (IBS-D); and for idiopathic/functional diarrhea. A second-generation proprietary anti secretory agent, NP-300 (lechlemer), is undergoing preclinical development for symptomatic relief and treatment of diarrhea in patients with acute infection from cholera. We believe Jaguar is poised to realize a number of synergistic, value adding benefits—and the above-referenced expanded pipeline of potential blockbuster human indications of crofelemer and NP-300—upon which to build global partnerships. Jaguar, through Napo, holds global unencumbered rights for crofelemer, Mytesi, and Canalevia-CA1. Additionally, several of the drug product opportunities in Jaguar’s crofelemer pipeline are backed Phase 2 and proof of concept evidence from human clinical trials. Nasdaq Communication and Compliance Minimum Bid Price Requirement On February 17, 2022 the Company received a letter from the Staff of Nasdaq indicating that the bid price of the Company’s common stock for the last 30 Under Nasdaq Listing Rule 5810(c)(3)(A), the Company has been granted a 180-calendar day grace period, or until August 16, 2022, to regain compliance with the minimum bid price requirement. The continued listing standard will be met if the Company evidences a closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days during the 180-calendar day grace period. On August 18, 2022, the Company received a notification letter from the Staff notifying the Company that it had been granted an additional 180 days, or until February 13, 2023, to regain compliance with the Minimum Bid Price Requirement based on the Company meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market with the exception of the bid price requirement, and the Company’s written notice of its intention to cure the deficiency during the second compliance period. In the event the Company does not regain compliance with the $1.00 bid price requirement by February 13, 2023, Nasdaq will provide written notification that the Company’s securities will be delisted. At that time, the Company may appeal Nasdaq’s determination to a Hearings Panel with a plan to regain compliance. The Company is diligently working to evidence compliance with the minimum bid price requirement for continued listing on Nasdaq; however, there can be no assurance that the Company will be able to regain compliance or that Nasdaq will grant the Company a further extension of time to regain compliance, if necessary. If the Company fails to regain compliance with the Nasdaq continued listing standards, its common stock will be subject to delisting from Nasdaq. Liquidity and Going Concern The Company, since its inception, has incurred recurring operating losses and negative cash flows from operations and has an accumulated deficit of $246.8 million as of June 30, 2022. The Company expects to incur substantial losses and negative cash flows in future periods. Further, the Company’s future operations, including the operations of substantially owned Italian subsidiary, Napo Therapeutics S.p.A., which include the satisfaction of current obligations, are dependent on the success of the Company’s ongoing development and commercialization efforts, as well as securing additional financing and generating positive cash flows from operations. There is no assurance that the Company will have adequate cash balances to maintain its operations. Although the Company plans to finance its operations and cash flow needs through equity and/or debt financing, collaboration arrangements with other entities, license royalty agreements, as well as revenue from future product sales, the Company does not believe its current cash balances are sufficient to fund its operating plan through one year from the issuance of these unaudited condensed consolidated financial statements. The Company has an immediate need to raise cash. There can be no assurance that additional funding will be available to the Company on acceptable terms, or on a timely basis, if at all, or that the Company will generate sufficient cash from operations to adequately fund operating needs. If the Company is unable to obtain an adequate level of financing needed for the long-term development and commercialization of our products, the Company will need to curtail planned activities and reduce costs. Doing so will likely have an adverse effect on our ability to execute our business plan; accordingly, there is substantial doubt about the ability of the Company to continue in existence as a going concern. The accompanying unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties. Reverse Stock Split On September 3, 2021, the Company filed the Certificate of Fifth Amendment to its Third Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware to effect a 1

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and on a basis consistent with the annual consolidated financial statements, and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of the results to be expected for the year ending December 31, 2022, or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by U.S. GAAP for complete financial statements. There has been no material change to the Company's significant accounting policies during the three and six months ended June 30, 2022, as compared to the significant accounting policies described in Note 2 of the “Notes to Consolidated Financial Statements” in the Company's Annual Report on Form 10-K as of and for the year ended December 31, 2021 which was filed to SEC on March 11, 2022. Except as noted above, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly the financial position as of June 30, 2022, results of operations for the three months and six months ended June 30, 2022 and 2021, changes in convertible preferred stock and stockholders' equity for the three and six months ended June 30, 2022 and 2021, and cash flows for the six months ended June 30, 2022 and 2021. The interim results are not necessarily indicative of the results for any future interim periods or for the entire year. Principles of Consolidation The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly-owned subsidiary. All inter-company transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its unaudited condensed consolidated financial statements and the accompanying notes. The accounting policies that reflect the Company’s more significant estimates and judgments and that the Company believes are the most critical to aid in fully understanding and evaluating its reported financial results are the valuation of stock options, valuation of hybrid instruments designated at fair value option (“FVO”), valuation of warrant liabilities, acquired in-process research and development (“IPR&D”), and useful lives assigned to long-lived assets; impairment assessment of non-financial assets; valuation adjustments for excess and obsolete inventory; allowance for doubtful accounts; deferred taxes and valuation allowances on deferred tax assets; evaluation and measurement of contingencies; and recognition of revenue, including estimates for product returns. Those estimates could change, and as a result, actual results could differ materially from those estimates. In March 2020, the World Health Organization declared the COVID-19 outbreak to be a pandemic. During the period ended June 30, 2022, the Company’s financial results were not significantly affected by the COVID-19 outbreak. The Company has considered all information available as of the date of issuance of these financial statements and the Company is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. The extent to which the COVID-19 outbreak affects the Company’s future financial results and operations will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the outbreak, and current or future domestic and international actions to contain and treat it. For a discussion of risks of COVID-19 relating to the Company’s business, see “Item 1A. - Risk Factors- Risks Related to Our Business- The novel coronavirus global pandemic could adversely impact our business, including our supply chain, clinical trials and commercialization of Mytesi and Canalevia.” Cash The Company’s cash on deposit may exceed United States federally insured limits at certain times during the year. The Company maintains cash accounts with certain major financial institutions in the United States. The Company does not have cash equivalents as of June 30, 2022 and December 31, 2021. Accounts Receivable Accounts receivable is recorded net of allowances for discounts for prompt payment and credit losses. The Company estimates an allowance for credit losses by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. The corresponding expense for the credit loss allowance is reflected in general and administrative expenses. The credit loss allowance was immaterial as of June 30, 2022 and December 31, 2021. In addition, the Company writes off an uncollectible accounts receivable that have a contractual maturity of one year or less when there is information indicating that the counterparty is in severe financial difficulty and there is no realistic prospect of recovery. Concentrations Cash is the financial instrument that potentially subjects the Company to a concentration of credit risk as cash is deposited with a bank and cash balances are generally in excess of Federal Deposit Insurance Corporation insurance limits. For the three and six months ended June 30, 2022 and 2021, substantially all of the Company’s revenue was derived from the sale of Mytesi. In looking at sales by the Company to distributors whose net revenue percentage of total net revenue was equal to or greater than 10%, for the three and six months ended June 30, 2022, the Company earned Mytesi revenue primarily from two specialty pharmacies located in the United States. For the three and six months ended June 30, 2021, the Company earned Mytesi revenue primarily from two specialty pharmacies in the United States. Revenue earned from each as a percentage of total revenue is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ Six Months Ended ​ ​ June 30, ​ ​ June 30, ​ ​ (unaudited) ​ ​ (unaudited) ​ ​ 2022 2021 ​ 2022 2021 Customer 1 ​ — % 84 % ​ — % 85 % Customer 2 ​ 34 % 11 % ​ 34 % 11 % Customer 3 ​ 49 % — % ​ 53 % — % Customer 4 ​ 10 % — % ​ 5 % — % ​ On September 3, 2021, the Company ended its engagement with Cardinal Health as its exclusive title model customer for commercial sales and fully implemented its limited distribution Specialty Pharmacy model. Cardinal Health continues to provide third-party logistics services for Mytesi. The Company is subject to credit risk from its accounts receivable related to its sales. The Company generally does not perform evaluations of customers' financial condition and generally does not require collateral. As of June 30, 2022 and December 31, 2021, the Company’s significant customers and their related accounts receivable balance as a percentage of total accounts receivable were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ ​ 2022 ​ December 31, ​ ​ (unaudited) ​ 2021 Customer 1 ​ — % ​ 16 % Customer 2 ​ 38 % ​ 37 % Customer 3 ​ 50 % ​ 37 % ​ The Company is subject to concentration risk from its suppliers. The Company sources raw material used to produce the active pharmaceutical ingredient (“API”) in Mytesi from two suppliers and is dependent on a single third-party contract manufacturer for the supply of API in Mytesi and a single third-party contract manufacturer as well for the supply of finished products for commercialization. Other Risks and Uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to war, rapid technological change, obtaining second source suppliers, regulatory approval from the FDA or other regulatory authorities, the results of clinical trials and the achievement of milestones, market acceptance of the Company’s product candidates, competition from other products and larger companies, protection of proprietary technology, strategic relationships and dependence on key individuals. Russia-Ukraine War In February 2022, the Russian Federation and Belarus commenced a military action against the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these unaudited condensed consolidated financial statements and the specific impact on the Company’s financial condition, results of operations and cash flows are also not determinable as of the date of these unaudited condensed consolidated financial statements. Fair Value The Company’s financial instruments include accounts receivable, accounts payable, accrued liabilities, warrant liabilities, equity-linked financial instruments and debt. The recorded carrying amounts of accounts receivable, accounts payable and accrued liabilities reflect their fair value due to their short-term nature. Other financial liabilities are initially recorded at fair value, and subsequently measured at either fair value or amortized cost using the effective interest method. See Note 4 for the fair value measurements. Fair Value Option ASC 825-10, Financial Instruments Inventory ​ Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Cost is initially recorded at the invoiced amount of raw materials or API, including the sum of qualified expenditures and charges in bringing the inventory to its existing condition and location. The Company calculates inventory valuation adjustments when conditions indicate that net realizable value is less than cost due to physical deterioration, usage, obsolescence, reductions in estimated future demand or reduction in selling price. Inventory write-downs are measured as the difference between the cost of inventory and net realizable value. The Company does Property and Equipment Land is stated at cost, reflecting the fair value of the property at July 31, 2017, the date of the Napo merger. Equipment is stated at cost, net of accumulated depreciation. Equipment begins to be depreciated when it is placed into service. Depreciation is calculated using the straight-line method over estimated useful lives ranging between 3 to 10 years. Expenditures for repairs and maintenance of assets are charged to expense as incurred. Costs of major additions and betterments are capitalized and depreciated on a straight-line basis over their estimated useful lives. Upon retirement or sale, the cost and related accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included in the unaudited condensed consolidated statements of operations. Long-lived Assets The Company regularly reviews the carrying value and estimated lives of all of its long-lived assets, including property and equipment and definite-lived intangible assets, to determine whether indicators of impairment exist that warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management’s estimate of the asset’s ability to generate positive income from operations and positive cash flow in future periods as well as the strategic significance of the assets to the Company’s business objectives. If the Company determines that an impairment trigger has been met, the Company evaluates the realizability of its long-lived assets (asset group) based on a comparison of projected undiscounted cash flows from use and eventual disposition with the carrying value of the related asset. Any write-downs (which are measured based on the difference between the fair value and the carrying value of the asset) are treated as permanent reductions in the carrying amount of the assets (asset group). Based on this evaluation, the Company believes that, as of each of the balance sheet dates presented, none of the Company’s long-lived assets were impaired. The Company’s had no impairment of long-lived assets as of June 30, 2022 and 2021. Indefinite-lived Intangible Assets Acquired IPR&D are intangible assets acquired in the July 2017 Napo merger. Under ASC 805, IPR&D are initially recognized at fair value and classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. During the development period, these assets will not be amortized as charges to earnings; instead, these assets will be tested for impairment on an annual basis or more frequently if impairment indicators are identified. An impairment loss is measured based on the excess of the carrying amount over the asset’s fair value. The Company recorded no impairment in the three and six months ended June 30, 2022 and 2021. Leases The Company accounts for its leases in accordance with ASC 842, Leases At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. Because the interest rate implicit in lease contracts is typically not readily determinable, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received. Operating Lease The Company entered into a sublease agreement with Peacock Construction Inc. (“Peacock”), a California corporation, for office space located in San Francisco, California. The term of the sublease began on August 31, 2020 and expired on May 31, 2021. The rent under the sublease is $15,000 per month beginning October 1, 2020, which includes operating expenses and taxes. On October 1, 2020, the Company transitioned its operations from its existing premises to the sublease premises, which the Company expects will serve as its principal administrative headquarters. The Company elected not to apply the recognition requirements to short-term leases, and instead recognize the lease payments in profit or loss on a straight-line basis over the lease term. As a result, there was no right-of-use asset and lease liability In April 2021, the Company entered into an office lease agreement with M & E, LLC, a California Limited Liability Company, to lease approximately 10,526 square feet of office space located in San Francisco, California, inclusive of office space currently covered under the sublease agreement with Peacock. The term of the lease began on September 1, 2021 and will expire on August 31, 2024, unless earlier terminated. The base rent under the lease will be $42,000 monthly for the first 12 months, $43,000 monthly for the next 12 months and $45,000 for the last twelve months. In October 2021, the Company entered into an agreement with Copernico Centrale for the lease of office premises from November 1, 2021 to April 30, 2022, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €10,000 or approximately $10,500. If the contract is not terminated within 12 months, the lease amount will be increased in line with the index of relevant inflation at each annual expiration of the start date of the contract. On January 26, 2022, the lease agreement was amended whereby the term was extended by 20 months from May 1, 2022 to December 31, 2023. All other contract provisions remained the same. In December 2021, the Company entered into an agreement with Arval Service Lease Italia SpA for the lease of two separate vehicles for 48 months expiring on November 30, 2025. Total monthly lease payment amounted to €2,000 or $2,100 payable in advance. The Company elected to include both the lease and non-lease components as a single component and account for it as a lease. The Company also paid a total deposit of €19,000 or approximately $20,000, exclusive of VAT. Early termination of the contracts requires the payment of specified amounts. In January 2022, the Company entered into an agreement with Copernico Centrale for the lease of office premises from March 1, 2022 to December 31, 2023, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €4,000 or approximately $4,200. A similar agreement was entered with the lessor for the lease of premises to be used as office space from November 1, 2022 to December 31, 2023, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €3,817 or approximately $4,000. If the contracts are not terminated within 12 months, the lease amounts will be increased in line with the index of relevant inflation at each annual expiration of the start date of the contract. In May 2022, the Company entered into an agreement with ALD Automative Italia S.r.l for the lease of one vehicle for 48 months expiring on April 30, 2026. Total monthly lease payment amounted to €833 or approximately $880 payable in advance. The Company elected to include both the lease and non-lease components as a single component and account for it as a lease. The Company also paid a total deposit of €21,000 or approximately $22,000, exclusive of VAT. Early termination of the contracts requires the payment of specified amounts. Research and Development Expense Research and development expense consists of expenses incurred in performing research and development activities including related salaries, clinical trials and related drug and non-drug product costs, contract services and other outside service expenses. Research and development expense is charged to operating expense in the period incurred. Clinical Trial Accruals Clinical trial costs are a component of research and development expenses. The Company accrues and expenses clinical trial activities performed by third parties based upon actual work completed in accordance with agreements established with clinical research organizations and clinical sites. The Company determines the costs to be recorded based upon validation with the external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers The Company’s policy typically permits returns if the product is damaged, defective, or otherwise cannot be used when received by the customer if the product has expired. Returns are accepted for product that will expire within three months or that have expired up to one year after their expiration dates. Estimates for expected returns of expired products are based primarily on an ongoing analysis of our historical return patterns. The Company recognizes revenue in accordance with the core principle of ASC 606 or when there is a transfer of control of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. The Company does not adjust the amount of consideration for the effects of a significant financing component if, at contract inception, the expected period between the transfer of promised goods or services and customer payment is one year or less. The Company has elected to treat shipping and handling activities as fulfillment costs. Additionally, the Company elected to record revenue net of sales and other similar taxes. Contracts – Cardinal Health and Other Distributors Effective January 16, 2019, the Company engaged Cardinal Health as its exclusive third-party logistics distribution agent for commercial sales of the Company’s Mytesi product and to perform certain other services which include, without limitation, storage, distribution, returns, customer support, financial support, Electronic Data Interchange (“EDI”) and system access support (the “Exclusive Distribution Agreement”). On September 3, 2021, the Company ended its engagement with Cardinal Health as its exclusive title model customer for commercial sales and fully implemented its limited distribution Specialty Pharmacy model. Cardinal Health continues to provide third-party logistics services for Mytesi. The Company's Canalevia, Neonorm and botanical extract products are primarily sold to distributors, who then sell the products to the end customers. Since 2014, the Company has entered into several distribution agreements with established distributors such as Animart, Vedco, VPI, RJ Matthews, Covetrus, and Stockmen Supply to distribute the Company's animal health products in the United States, Japan, and China. The distribution agreements and the related purchase order together meet the contract existence criteria under ASC 606-10-25-1. The Company sells directly to its customers without the use of an agent. Performance obligations For animal health products sold by the Company, the single performance obligation identified above is the Company’s promise to transfer the Company’s animal products to distributors based on specified payment and shipping terms in the arrangement. Product warranties are assurance-type warranties that do not represent a performance obligation. For the Company’s human health product, Mytesi, the single performance obligation identified above is the Company’s promise to transfer Mytesi to Cardinal Health, based on specified payment and shipping terms as outlined in the Exclusive Distribution Agreement. Transaction price For contracts with Cardinal Health and other distributors, the transaction price is the amount of consideration to which the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi, Canalevia and Neonorm is the Wholesaler Acquisition Cost (“WAC”), net of discounts, returns, and price adjustments. Allocate transaction price For contracts with Cardinal Health and other distributors, the entire transaction price is allocated to the single performance obligation contained in each contract. Revenue recognition For contracts with Cardinal Health and other distributors, a single performance obligation is satisfied at a point in time, upon the free on board (“FOB”) terms of each contract when control, including title and all risks, has transferred to the customer. Disaggregation of Product Revenue Human Sales of Mytesi are recognized as revenue at a point in time when the products are delivered to the wholesaler. Net revenue from the sale of Mytesi were $384,000 and $317,000 for the three months ended June 30, 2022 and 2021, respectively. Net revenue from the sale of Mytesi were $723,000 and $1.3 million for the six months ended June 30, 2022 and 2021. Animal The Company recognized Canalevia product revenues were $87,000 and zero for the three months ended June 30, 2022 and 2021, respectively. Revenues from the sale of Canalevia were $131,000 and zero for the six months ended June 30, 2022 and 2021, respectively. Neonorm revenues of $15,000 and $6,000 for the three months ended June 30, 2022 and 2021, respectively. Revenues from the sale of Neonorm were $35,000 and $39,000 for the six months ended June 30, 2022 and 2021, respectively. Revenues are recognized at a point in time upon shipment, which is when title and control is transferred to the buyer. Sales of Canalevia-CA1, Neonorm Calf and Foal to distributors are made under agreements that may provide distributor price adjustments and rights of return under certain circumstances. Contracts – Specialty Pharmacies Effective October 1, 2020, the Company engaged a private company as its third-party logistics distribution agent for commercial sales of the Company’s Mytesi product. Under the Specialty Product Distribution Agreement, the Company shall supply the products to the private company’s specialty pharmacies, through a designated wholesaler, in such amounts as may be ordered. There is no minimum purchase or inventory requirement. The specialty pharmacies were authorized distributors of record for all National Drug Codes (“NDCs”) of Mytesi. Effective April 20, 2021, the Company engaged another private company as an authorized specialty pharmacy provider of Mytesi. Under the Specialty Pharmacy Distribution and Services Agreement, the private company shall sell and dispense the Mytesi directly ordered from the Company at the agreed price to patients within the territories identified in the agreement. The two contracts with the four specialty pharmacies were combined into one portfolio of contract as they share similar characteristics. Performance obligations The single performance obligation is the Company’s promise to transfer Mytesi to specialty pharmacies, based on specified payment and shipping terms as outlined in the agreements. Transaction price The transaction price is the amount of consideration to which the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi is the WAC, net of estimated discounts, returns, and price adjustments. Allocate transaction price The entire transaction price is allocated to the single performance obligation contained in each contract. Revenue recognition The single performance obligation is satisfied at a point in time, upon the free on board (“FOB”) terms of each contract when control, including title and all risks, has transferred to the customer. Disaggregation of Product Revenue Sales of Mytesi are recognized as revenue at a point in time when products are delivered to the specialty pharmacies. Net revenue from the sale of Mytesi to the specialty pharmacies were $2.4 million and $62,000 for the three months ended June 30, 2022 and 2021, respectively. Net revenue from the sale of Mytesi to the specialty pharmacies were $4.7 million and $237,000 for the six months ended June 30, 2022 and 2021, respectively. Collaboration Revenue Revenue recognition for collaboration agreements requires significant judgment. The Company’s assessments and estimates are based on contractual terms, historical experience and general industry practice. Revisions in these values or estimations have the effect of increasing or decreasing collaboration revenue in the period of revision. On September 24, 2018, the Company entered into a Distribution, License and Supply Agreement (“License Agreement”) with Knight Therapeutics ("Knight"). The License Agreement has a term of 15 years (with automatic renewals) and provides Knight with an exclusive right to commercialize current and future Jaguar human health products (including crofelemer, Lechlemer, and any product containing a proanthocyanidin or with an anti-secretory mechanism) in Canada and Israel. Knight forfeited its right of first negotiation for expansion to Latin America. Under the License Agreement, Knight is responsible for applying for and obtaining necessary regulatory approvals in the territory of Canada and Israel, as well as marketing, sales and distribution of the licensed products. Knight will pay a transfer price for all licensed products, and upon achievement of certain regulatory and sales milestones, the Company may receive payments from Knight in an aggregate amount of up to approximately $18 million payable throughout the initial 15-year term of the agreement. The Company did not have any license revenues for the three and six months ended June 30, 2022 and 2021. On June 21, 2022, the Company entered into a License Agreement (“License Agreement”) with SynWorld Technology Corporation (“Synworld”). The License Agreement grants Synworld an exclusive, non-transferable, non-sublicensable license of patents and know-how to significantly improve and/or expand the scope of the Company’s intellectual property rights and to commercialize a canine-specific pharmaceutical product that utilizes Crofelemer as its active drug substance marketed in the United States under the Trademark Canalevia®, Canalevia-CA1 and Canalevia CA-2 (“Product”) for the treatment, prevention, or amelioration of diarrhea in dogs in China, excluding Hong Kong (“Licensee Territory”). Synworld is responsible to prepare, submit and obtain all regulatory approvals for the Product in the Licensee Territory on behalf of, and in the name of the Company (the “Services”). During the Initial Term, Synworld will be solely responsible for all fees and expenses incurred by or on behalf of Synworld with respect to the performance of the Services (“Regulatory Expense”), subject to both parties’ election for the Company to reimburse Regulatory Expenses up to $2.0 million (“Reimbursement Cap”). All Regulatory Expenses in excess of the Reimbursement Cap and any additional fees and expenses incurred thereafter for maintaining the regulatory approvals will be borne by Synworld. As consideration for the license granted, Synworld should make non-refundable cash payments with an aggregate amount of $5.0 million during the initial two-year term of the agreement. The Company did not have any license revenues for the three and six months ended June 30, 2022 and 2021. Modifications to Liability-classified Instruments In accounting for debt modifications and exchange transactions, it is the Company’s policy to first determine whether it qualifies as a troubled debt restructuring (“TDR”) pursuant to the guidance provided in ASC 470-60. A debt modification or exchange transaction that is not within the scope of the ASC 470-60 is accounted for under ASC 470-50 to determine if the transaction is a mere modification or an extinguishment. In the three and six months ended June 30, 2021, the Company amended the terms of its October 2020 Purchase Agreement and Exchange Note 2, respectively. In the three and six months ended June 30, 2022, the Company entered into another amendment on the terms of its October 2020 Purchase Agreement (see Note 8). Modifications to Equity-classified Instruments ​ In accounting for modifications of equity-classified warrants, it is the Company’s policy to determine the impact by analogy to the share-based compensation guidance of ASC 718, Compensation - Stock Compensation modification is recognized as an expense in the statements of operations to the extent the modified instrument has a higher fair value; however, in certain circumstances, such as when an entire class of warrants is modified, the measured increase in fair value may be more appropriately recorded as a deemed dividend, depending upon the nature of the warrant modification. The Company did not modify any equity-classified warrants in the three and six months ended June 30, 2022 and 2021. In accounting for amendments to preferred stock, it is the Company’s policy to measure the impact by analogy to ASC 470-50 in determinin

The October 2018 Underwriter Warrants valuation of $1,000 at December 31, 2021 was computed using the Black-Scholes-Merton pricing model using a stock price of $1.04, a strike price of $158 per share, an expected term of 1.75 years, volatility of 180% and a risk-free discount rate of 0.65%. The change in the fair value of the warrants for the three and six months ended June 30, 2022 was $1,000. The November 2016 Series A Warrants Series A Warrants has expired on May 29, 2022. The Series A warrant valuation of zero at December 31, 2021 was computed using the Black-Scholes-Merton pricing model using a stock price of $1.04, a strike price of $2,363 per share, an expected term of 0.41 years, volatility of 89% and a risk-free discount rate of 0.19%. The change in fair value of the warrants for the three and six months ended June 30, 2022 was zero. The May 2020 Series 3 Warrants There were no outstanding May 2020 Series 3 Warrants as of June 30, 2022 and December 31, 2021. For the year ended December 31, 2021, certain holders of the Series 3 Warrants agreed to exercise total of 206,915 shares for a 1-for-1 exchange of common shares in an Alternate Cashless Exercise. The aggregate fair value of the common stock issued upon the exercise of the Series 3 Warrants as of the exercise date was $1.8 million. Streeterville Note The fair value of the Streeterville Note at January 13, 2021, date of issuance and as of June 30, 2022 amounting to $6.0 million and $7.3 million, respectively, were based on the weighted average discounted expected future cash flows representing the terms of the note, discounting them to their present value equivalents. This was classified as Level 3 fair values in the fair value hierarchy due to the use of unobservable inputs, including the Company’s own credit risk. The Company determined and performed the valuations of the Streeterville Note with the assistance of an independent valuation service provider. On a quarterly basis, the Company considers the main Level 3 inputs used derived as follows: ● Discount rate for the Streeterville note which was determined using a comparison of various effective yields on bonds as of the valuation date ● Market indications for vouchers, which affect the Return Bonus from the sale of Tropical Disease Priority Review Voucher (“TDPRV”) ● Weighted probability of cash outflows which was estimated based on the entity's knowledge of the business and how the current economic environment is likely to impact the timing of the cash outflows, attributed to the different repayment features of the note The following table summarizes the quantitative information about the significant unobservable inputs used in Level 3 fair value measurement: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Range of Inputs ​ ​ ​ ​ (probability-weighted average) ​ Relationship of unobservable inputs Unobservable Inputs ​ 2022 ​ 2021 ​ to fair value Risk Adjusted Discount Rate ​ 11.94%-26.47% (26.47%) ​ 6.78% - 21.31% (21.31%) ​ If discount rate is adjusted to total of additional 100 basis points (bps), fair value would have decreased by $277,000. Sales Proceeds: Amount of comparable TDPRV ​ $67.5 million to $350 million ($100 million) ​ $67.5 million to $350.0 million ($100.0 million) ​ If expected cash flows by Management considered the lowest amount of market indications for vouchers, FV would have decreased by $1.09 million. Range of Probability for Timing of Cash Flows: ​ 0.39%-41.88% ​ 0.35%-46.06% ​ If expected cash flows by Management considered the Scenario with the least amount of indicated value, FV would have decreased by $247,000. ​ Fair Value Option Beginning January 1, 2021, the Company elected to apply the FVO accounting to selected financial instruments to align the measurement attributes of those instruments under U.S. GAAP and to simplify the accounting model applied to those financial instruments. The Company elected to apply FVO accounting to the entire class of hybrid instruments, including structured notes, of which there are assessed embedded derivatives that would be eligible for bifurcation. Changes in the fair value of FVO assets and liabilities as well as the mark-to-market adjustment on the entire class of hybrid instruments, including derivatives and the net realized gains or losses on these instruments are reported in the change in fair value of financial instruments in the unaudited condensed consolidated statements of operations. As of June 30, 2022, the Company did not note any fair value movement on FVO liabilities attributable to any instrument-specific credit risk, which is recorded in other comprehensive loss. Hybrid Instruments The Company elected to apply FVO accounting to all of the hybrid instruments issued, including structured notes. The valuation of the hybrid instruments is predominantly driven by the derivative features embedded within the instruments. The Company determined and performed the valuations of the hybrid instruments with the assistance of an independent valuation service provider. The valuation methodology utilized is consistent with the income approach for estimating the fair value of the interest-bearing portion of the instrument and the related derivatives. Cash flows of the hybrid instruments in their entirety, including the embedded derivatives, are discounted at an appropriate rate for the applicable duration of the instrument. Interest on the interest-bearing portion of the instrument that is held to maturity is aggregated as gain (loss) on instruments designated at fair value and related derivatives in the change in fair value of financial instruments and hybrid instruments designated at FVO of the unaudited condensed consolidated statements of operations.

Following the completion of document discovery, the parties engaged in a mediation that resulted in an agreement in principle to settle the litigation on a class-wide basis for $2.6 million. On May 27, 2021, the court gave the final approval to the proposed settlement and the entire settlement consideration will be provided by the Company’s director and officer liability insurance carrier. Under the loss recovery model in ASC 450 and in reference to ASC 410, the ultimate net income effect of the recognized loss and the insurance proceeds directly related to the recognized loss is zero . Severance Agreements In June 2020, the Company entered into certain agreements relating to the payment of severance and other benefits to executive officers of the Company, the severance agreements provide for compensation and benefits if the executive officer is subject to (a) a termination of employment by the Company without cause or (b) a good reason termination, within three months following a change in control. Contingencies From time to time, the Company maybe a party to various legal actions, both inside and outside the U.S., arising in the ordinary course of its business or otherwise. The Company accrues amounts, to the extent they can be reasonably estimated, that the Company believes will result in a probable loss (including, among other things, probable settlement value), to adequately address any liabilities related to legal proceedings and other loss contingencies. A loss or a range of loss is disclosed when it is reasonably possible that a material loss will incur and can be estimated, or when it is reasonably possible that the amount of a loss, when material, will exceed the recorded provision. The Company did not have any material accruals for any currently active legal action in its consolidated balance sheets as of June 30, 2022, as the Company could not predict the ultimate outcome of these matters, or reasonably estimate the potential exposure.

Timing of maturities may fluctuate based on future revenue. Sale of Future Royalty Interest October 2020 Purchase Agreement On October 8, 2020, the Company entered into another royalty interest purchase agreement (the “October 2020 Purchase Agreement”) with Iliad, pursuant to which the Company sold to Iliad a royalty interest entitling Iliad to receive $12.0 million of future royalties on sales of Mytesi and certain up-front license fees and milestone payments from licensees and/or distributors (the “Royalty Repayment Amount”) for an aggregate purchase price of $6.0 million. Until such time as the Royalty Repayment Amount has been paid in full, the Company will pay Iliad 10% of the Company’s net sales on included products and 10% of worldwide revenues related to upfront licensing fees and milestone payments from licensees and/or distributors, but specifically excluding licensing fees and/or milestone payments that are reimbursements of clinical trial expenses (the “Royalty Payments”). Beginning on the six-month anniversary of the delivery of the October 2020 Purchase Agreement to the Company (the “Purchase Price Date”) and continuing until the 12-month anniversary of the Purchase Price Date, the monthly Royalty Payment shall be the greater of (a) $250,000, and (b) the actual Royalty Payment amount Iliad is entitled to for such month. Beginning on the 12-month anniversary of the Purchase Price Date and continuing until 18-month anniversary of the Purchase Price Date, the monthly Royalty Payment shall be the greater of (a) $400,000 and (b) the actual Royalty Payment amount Iliad is entitled to for such month. Beginning on the 18-month anniversary of the Purchase Price Date and continuing until 24-month anniversary of the Purchase Price Date, the monthly Royalty Payment shall be the greater of (a) $600,000 and (b) the actual Royalty Payment amount Iliad is entitled to for such month. Beginning on the 24-month anniversary of the Purchase Price Date and continuing until the Royalty Repayment Amount has been paid in full, the monthly Royalty Payment shall be the greater of (a) $750,000, and (b) the actual Royalty Payment amount Iliad is entitled to for such month. The Royalty Interest amount of $12.0 million was classified as debt, net of a $6.0 million discount, at initial recognition. Under ASC 470-10-35-3, royalty payments to Iliad will be amortized under the interest method per ASC 835-30. Because there is no set interest rate, and because the royalty payments are variable, the discount rate is variable. After each royalty payment, the Company will use a prospective method to determine a new discount rate based on the revised estimate of remaining cash flows. The new rate is the discount rate that equates the present value of the revised estimate of remaining cash flows with the carrying amount of the debt, and it will be used to recognize interest expense for the remaining periods. At issuance, based on projected cash outflows from future revenue streams, the discount rate was 34.51% . Pursuant to the October 2020 Purchase Agreement, if the weekly volume weighted average price (“VWAP”) of the Company’s common stock is not equal or greater than the minimum VWAP of $0.9105 at least twice during each calendar month during the six-month period beginning on November 1, 2020, then the Royalty Repayment Amount will be automatically increased by $6.0 million at the end of such six-month period. During the observation period starting November 1, 2020, the Company’s weekly VWAP failed to reach the minimum VWAP of $0.9105 and on November 13, 2020, the Company concluded that the contingent clause has been met, warranting an additional $6.0 million Royalty Repayment Amount, to be added to the outstanding balance commencing on May 10, 2021 for the purpose of cash interest calculation. The change in the Royalty Repayment Amount was accounted for as a debt modification and resulted in a new discount rate of 45.42%. On April 13, 2021, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $3.0 million from the original outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 588,235 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. The exchange agreement was accounted for as a modification and resulted in a new discount rate of 77.09%. On February 11, 2022, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $2.4 million from the outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 1,733,750 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. On March 2, 2022, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $1.1 million from the outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 2,425,000 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. On March 4, 2022, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $800,000 from the outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 2,000,000 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. On March 9, 2022, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $700,000 from the outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 1,850,000 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. Because the period between the first and last exchanges occurred within a 12-month period and each was individually assessed as a modification, the debt terms that existed prior to the February 13 exchange was used in the application of the 10% test on the cumulative assessment performed. The exchanges were cumulatively accounted for as an extinguishment and resulted to a loss of $2.2 million. On April 14, 2022, the Company entered into amendments (the “Royalty Interest Global Amendments”) to its existing royalty interests including the Royalty Interest in the original principal amount of $12.0 million under the October 2020 Royalty Interest. The amendment grants the Company at its sole discretion, the right to exchange from time to time, all or any portion of the Royalty Interests for shares of the Company’s common stock at a price per share equal to the Nasdaq Minimum Price (as defined in Nasdaq Listing Rule 5635(d)) as of date of the applicable exchange. Under the Royalty Interest Global Amendments, the Company’s ability to exchange the Royalty Interests for shares of the Company’s common stock is subject to certain limitations, on which the Company will not have such right and issue any common stock to investors if (a) the issuance of the Company’s common shares would cause investor’s beneficial ownership to exceed 4.99% of Company’s issued and outstanding common stock as of such date; (b) any of the exchange conditions has not been satisfied as of the applicable exchange date; and (c) the total cumulative number of shares of the Company’s common stock issued pursuant to the Royalty Interests would exceed the requirements of The Nasdaq Capital Market (including the rules related to the aggregation of offerings under Nasdaq Listing Rule 5635(d) if applicable) (the “Exchange Cap”), unless stockholder approval is obtained to issue more than the Exchange Cap. The Exchange Cap shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction. On May 13, 2022, the Company entered into an exchange agreement with Iliad, pursuant to which the parties agreed to partition $400,000 from the outstanding balance of the royalty interest. The parties further agreed to exchange the partitioned royalty for 1,143,643 shares of the Company’s common stock. The exchange consisted of Iliad surrendering the partitioned royalty in exchange for the exchange shares. Although there were exchanges that occurred within the 12-month period prior to the May 13, 2022 exchange, these were previously accounted for as extinguishment and, therefore, cumulative assessment was not anymore performed. The exchange agreement was accounted for as a modification. As of June 30, 2022, the forecasted future revenues changed which resulted to a new discount rate of 38.02%. Interest expense for the three and six months ended June 30, 2022 was $737,000 and $2.1 million, respectively. Interest expense for the three and six months ended June 30, 2021 was $952,000 and $2.0 million, respectively. As of June 30, 2022 and December 31, 2021, the carrying value of the debt is $7.9 million and $6.3 million, respectively. December 2020 Purchase Agreement ​ On December 22, 2020, the Company entered into a royalty interest purchase agreement (the “December 2020 Purchase Agreement”) with Irving Park Capital, LLC (“Irving”), a company affiliated with CVP, pursuant to which the Company sold to Irving a royalty interest entitling Irving to receive $12.0 million of future royalties on sales of Mytesi and certain up-front license fees and milestone payments from licensees and/or distributors (the “Royalty Repayment Amount”) for an aggregate purchase price of $6.0 million. Until such time as the Royalty Repayment Amount has been paid in full, the Company will pay Irving 10% of the Company’s Net Sales on Included Products and 10% of worldwide revenues related to upfront licensing fees and milestone payments from licensees and/or distributors, but specifically excluding licensing fees and/or milestone payments that are reimbursements of clinical trial expenses (the “Royalty Payments”). Beginning on the payment start date of March 8, 2024 and continuing until the 12-month anniversary of the Purchase Price Date, the monthly Royalty Payment shall be the greater of (a) $750,000, and (b) the actual Royalty Payment amount Irving is entitled to for such month. The Royalty Interest amount of $12.0 million is classified as debt, net of a $6.0 million discount, at initial recognition. Under ASC 470-10-35-3, royalty payments to Irving will be amortized under the interest method per ASC 835-30. Because there is no set interest rate, and because the royalty payments are variable, the discount rate is variable. After each royalty payment, the Company will use a prospective method to determine a new discount rate based on the revised estimate of remaining cash flows. The new rate is the discount rate that equates the present value of the revised estimate of remaining cash flows with the carrying amount of the debt, and it will be used to recognize interest expense for the remaining periods. At issuance, based on projected cash outflows from future revenue streams, the discount rate was 23.70%. As of June 30, 2022, the forecasted future revenues changed which resulted to a new discount rate of 29.55%. On April 14, 2022, under the Royalty Interest Global Amendments, the Company is granted at its sole discretion, the right to exchange from time to time, all or any of the Royalty Interest under the original principal amount of $12.0 million or any portion of the December 2020 Purchase Agreement for shares of the Company’s common stock at a price per share equal to the Nasdaq Minimum Price (as defined in Nasdaq Listing Rule 5635(d)) as of date of the applicable exchange, subject to certain limitations. Interest expense for the three and six months ended June 30, 2022 was $962,000 and $1.7 million, respectively. Interest expense for the three and six months ended June 30, 2021 was $701,000 and $1.4 million, respectively. As of June 30, 2022 and December 31, 2021, the carrying value of the debt is March 2021 Purchase Agreement On March 8, 2021, the Company entered into a purchase agreement (the “March 2021 Purchase Agreement”) with Streeterville Capital, LLC (“Streeterville”), a company affiliated with CVP, pursuant to which the Company sold a royalty interest entitling Streeterville to $10.0 million and any interest, fees, and charges as royalty repayment amount for an aggregate purchase price of $5.0 million. Interest will accrue on the royalty repayment amount at a rate of 5% per annum, compounding quarterly, and will increase to 10% per annum, compounding quarterly on the 12-month anniversary of the closing date. The Company will be obligated to make minimum royalty payments on a monthly basis beginning at the earlier of (a) 36 months following the closing date or (b) 30 days following the satisfaction of all existing royalties to Streeterville, and its affiliates namely Iliad and Irving, but not earlier than 18 months following the closing date in an amount equal to the greater of (i) $250,000 beginning on the royalty payment start date and continuing until either the royalty repayment amount has been paid in full or the 6-month anniversary of the royalty payment start date, $400,000 beginning on the 6-month anniversary of the royalty payment start date and continuing until either the royalty repayment amount has been paid in full or the 12-month anniversary of the royalty payment start date, $600,000 beginning on the 12-month anniversary of the royalty payment start date and continuing until either the royalty repayment amount has been paid in full or the 18-month anniversary of the royalty payment start date, $750,000 beginning on the 18-month anniversary of the royalty payment start date and continuing until the royalty repayment amount has been paid in full, and (ii) 10% of the Company’s net sales on included products, 10% of worldwide revenues related to upfront licensing fees and milestone payments from licensees and/or distributors but specifically excluding licensing fees and/or milestone payments that are reimbursements of clinical trial expenses or associated with the license of Included Products from the Company to Napo EU, including but not limited to the upfront fee payable by Napo EU to Napo for included products and Crofelemer for other indications; and 50% of royalties collected from licenses of the included products to third parties. The Royalty Interest amount of $10.0 million is classified as debt, net of a $5.0 million discount, at initial recognition. Under ASC 470-10-35-3, royalty payments to Streeterville will be amortized under the interest method per ASC 835-30. Because there is no set interest rate, and because the royalty payments are variable, the discount rate is variable. After each royalty payment, the Company will use a prospective method to determine a new discount rate based on the revised estimate of remaining cash flows. The new rate is the discount rate that equates the present value of the revised estimate of remaining cash flows with the carrying amount of the debt, and it will be used to recognize interest expense for the remaining periods. At issuance, based on projected cash outflows from future revenue streams, the discount rate was 19.36%. As of June 30, 2022, the forecasted future revenues changed which resulted to a new discount of 20.59%. On April 14, 2022, under the Royalty Interest Global Amendments, the Company is granted at its sole discretion, the right to exchange from time to time, all or any of the Royalty Interest under the original principal amount of $10.0 million of the March 2021 Purchase Agreement for shares of the Company’s common stock at a price per share equal to the Nasdaq Minimum Price (as defined in Nasdaq Listing Rule 5635(d)) as of date of the applicable exchange, subject to certain limitations. Interest expense for the three and six months ended June 30, 2022 was $595,000 and $1.0 million, respectively. Interest expense for the three and six months ended June 30, 2021 was $377,000 and $439,000, respectively. As of June 30, 2022 and December 31, 2022, the carrying value of the debt is $6.4 million and $5.8 million, respectively. Streeterville Note On January 13, 2021, the Company issued a secured promissory note to Streeterville in the original principal amount of $6.2 million for an aggregate purchase price of $6.0 million. The Company will use the proceeds to fund development of the Company’s NP-300 (lechlemer) drug product candidate for the indication of the symptomatic relief of diarrhea from cholera and general corporate purposes, including the Company’s product pipeline activities. The note is due after four years and bears interest at 3.25% per annum. Interest on the note is payable annually in advance by adding the interest charge for each upcoming year to the outstanding balance on the date each such interest charge is accrued. The Company also paid $25,000 to cover legal fees, accounting costs, due diligence, monitoring and other transaction costs incurred in connection with the issuance of the note. The first year of prepaid interest and the transaction expenses are included in the original principal amount. At any time following the occurrence of a trial failure which refers to any of the following: (i) the Company abandons the clinical trial with lechlemer for an indication for the symptomatic relief of infectious diarrhea for cholera; (ii) the Company fails to start the Phase 1 clinical trial of lechlemer for the symptomatic relief of infectious diarrhea for cholera by July 1, 2022; or (iii) the Company fails to meet all primary endpoints in the pivotal trials of Lechlemer for the symptomatic relief if infectious diarrhea for cholera with statistical significance, Streeterville may elect to increase the outstanding balance as of the date of the trial failure by 25% without acceleration (the “Trial Failure Effect”). If Streeterville elects to apply the Trial Failure Effect, it reserves the right to declare the outstanding balance immediately due and payable at any time. As of June 30, 2022, no trial failure occurred. Streeterville is entitled to a maximum of 18% and a minimum of 1% of the gross proceeds received by the Company from the sale of TDPRV (the “Return Bonus”). The Return Bonus percentage is reduced pro rata based on the percentage of the original principal balance of the note that has been repaid as of the date of the sale of the TDPRV. Even if the note has been paid in full at the time of the sale of the TDPRV, the Company is still obliged to pay Streeterville a Return Bonus of 1%. If Streeterville applies the Trial Failure Effect, the Return Bonus will automatically be reduced to 1%. If the TDPRV has not been sold as of the day immediately preceding the maturity date of the note, the Return Bonus percentage will be fixed as of such date. As of June 30, 2022, the Company has not sold any TDPRV. Beginning on the earlier of (a) 6 months after January 2021, and (b) initiation of human trials with lechlemer for symptomatic relief of infectious diarrhea for cholera, the Company may pay all or any portion of the outstanding balance earlier than it is due. In the event the Company elects to prepay all or any portion of the outstanding balance, it shall pay to Streeterville 112.5% of the portion of the outstanding balance the Company elects to prepay. The Company may not prepay the note without the Streeterville’s consent on the date the last patient is enrolled in a pivotal trial. After Streeterville becomes aware of the occurrence of any default, Streeterville may accelerate the note, with the outstanding balance becoming immediately due and payable in cash at the Mandatory Default Amount (i.e., the outstanding balance following the application of the Default Effect). Streeterville reserves the right to declare the outstanding balance immediately due and payable at any time following the default. Default Effect means multiplying the outstanding balance as of the date of default by 5% or 15% for each occurrence of default, capped at an aggregate of 25%, and then adding the resulting product to the outstanding balance. The percentage to be used depends on whether the default is viewed as minor or major as defined in the agreement. Furthermore, interest accrues on the outstanding balance beginning on the date of default at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. As of June 30, 2022, no default has occurred. In connection with the note issuance, the Company has entered into a security agreement with Streeterville, pursuant to which Streeterville will receive a first priority security interest in all existing and future lechlemer technology, and any TDPRV and the sale proceeds therefrom that may be granted to the Company by the FDA in connection with the development of lechlemer for the cholera indication. The Company also agreed, with certain exceptions, not to grant any lien on any of the collateral securing the note and not to grant any license under any of the intellectual property relating to such collateral. The grant of security interest has become effective upon the receipt of the Salix Waiver on April 6, 2021 in observance to the requirement of the settlement agreement previously entered by the Company with Salix Pharmaceuticals, Inc. The Company irrevocably elected to initially and subsequently apply the FVO accounting to the entire note. The fair value at transaction date was equal to the cash proceeds received of $6.0 million. The transaction expense of $25,000 was recognized in profit and loss as incurred. The Company used the valuation report from an independent valuation service provided to measure the reporting date fair value of the note. On April 14, 2022, the Company and Napo (together with the Company, the “Borrower”), entered into an amendment (the “Note Global Amendment”) to the secured promissory note in the original principal amount of $6.2 million with Streeterville, pursuant to which the Borrower was granted the right to exchange from time to time at Borrower’s sole discretion, all or any portion of the Note for shares of the Company’s common stock at a price per share equal to the Exchange Price. Under the Note Global Amendment, the Borrower’s ability to exchange the Note for shares of the Company’s common stock is subject to certain limitations, including no exchange transaction to the extent the issuance of shares in such exchange would result in the total cumulative number of shares of the Company’s common stock issued pursuant to the Note would exceed the Exchange Cap, unless stockholder approval is obtained to issue more than the Exchange Cap. At June 30, 2022 and December 31, 2021, the fair value was determined to be $7.3 million and $7.8 million, respectively. For the three and six months ended June 30, 2022, the net decrease in the fair value $709,000 and $476,000, respectively. For the three and six months ended June 30, 2021, the net increase in the fair value was $475,000 and $1,074,000, respectively.

In December 2020, the Company received cash proceeds of $1.6 million from Oasis (the “Tranche #6 Secured Note”). Oasis purchased accounts receivable with a carrying value of $2.2 million, or gross accounts receivable of $3.8 million net of chargebacks and discounts of $1.6 million. In February 2021, the Company made its final required payment to Oasis under Tranche #6 Secured Note, with total payments equaling the $1.8 million Threshold amount plus the transaction fee, and the Tranche #6 Secured Note was extinguished. Exchange Note 2 ​ In May 2019, CVP and the Company agreed to exchange two Napo convertible notes for a single CVP Note (“Exchange Note 1”). Per agreement, in consideration of the extension of the maturity date of Exchange Note 1 from December 31, 2019 to December 31, 2020, the Company issued a note (“Exchange Note 2”) with a principal balance of $2.3 million. The maturity date of Exchange Note 2 is December 31, 2020, with an interest rate of 10%. Between September 2020 and November 2020, the Company and CVP entered into a series of note exchange agreements pursuant to which the Company made prepayments of principal and related accrued interest of an aggregate amount of $5.0 million, in lieu of making cash payments to CVP on Exchange Note 1, by issuing a total of 6,740,573 shares of the Company’s common stock to CVP. The series of exchanges was accounted for as an extinguishment which resulted in a loss of $560,000. As of December 31, 2020, the carrying value of Exchange Note 1 was zero. In September 2020, the Company and CVP also entered into a global amendment agreement, pursuant to which the maturity date of Exchange Note 2 is extended to December 31, 2021. In consideration of CVP’s grant of extension, together with the related fees and other accommodation set forth, principal debt was increased by 5% of the outstanding balance of Exchange Note 2, which was $2.6 million as of the global amendment date. The global amendment requires redemption of Series D Perpetual Preferred Stock prior to payment of principal of Exchange Note 2. The Company determined the incremental value of cash flows amounting to $228,000 with the assistance of an independent valuation service provider, based on weighted probability assumptions of various settlement conditions and penalties stipulated in the contract therein. The global amendment agreement was accounted for as a modification; hence a new effective rate was determined at the date of modification that equated the revised cash flows to the carrying amount of the note.

Common stock equivalents are only included when their effect is dilutive. The Company's potentially dilutive securities which include stock options, convertible preferred stock, RSUs and common stock warrants have been excluded from the computation of diluted net loss per share as they would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to compute basic and diluted shares outstanding due to the Company's net loss position. The following outstanding common stock equivalents have been excluded from diluted net loss per common share for the three and six months ended June 30, 2022 and 2021 because their inclusion would be anti-dilutive. ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ June 30, ​ 2022 ​ 2021 ​ ​ (unaudited) Options issued and outstanding ​ 2,323,032 ​ 2,464,803 Inducement options issued and outstanding ​ 128,072 ​ 38,289 Restricted stock units issued and outstanding ​ 3,376,086 ​ 487,456 Warrants issued and outstanding ​ 563,451 ​ 563,451 Total ​ 6,390,641 ​ 3,553,999 ​ As of August 19, 2022, there were 32,746,090 shares of common stock issued after the balance sheet date.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and on a basis consistent with the annual consolidated financial statements, and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of the results to be expected for the year ending December 31, 2022, or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by U.S. GAAP for complete financial statements. There has been no material change to the Company's significant accounting policies during the three and six months ended June 30, 2022, as compared to the significant accounting policies described in Note 2 of the “Notes to Consolidated Financial Statements” in the Company's Annual Report on Form 10-K as of and for the year ended December 31, 2021 which was filed to SEC on March 11, 2022. Except as noted above, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly the financial position as of June 30, 2022, results of operations for the three months and six months ended June 30, 2022 and 2021, changes in convertible preferred stock and stockholders' equity for the three and six months ended June 30, 2022 and 2021, and cash flows for the six months ended June 30, 2022 and 2021. The interim results are not necessarily indicative of the results for any future interim periods or for the entire year.
Principles of Consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly-owned subsidiary. All inter-company transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its unaudited condensed consolidated financial statements and the accompanying notes. The accounting policies that reflect the Company’s more significant estimates and judgments and that the Company believes are the most critical to aid in fully understanding and evaluating its reported financial results are the valuation of stock options, valuation of hybrid instruments designated at fair value option (“FVO”), valuation of warrant liabilities, acquired in-process research and development (“IPR&D”), and useful lives assigned to long-lived assets; impairment assessment of non-financial assets; valuation adjustments for excess and obsolete inventory; allowance for doubtful accounts; deferred taxes and valuation allowances on deferred tax assets; evaluation and measurement of contingencies; and recognition of revenue, including estimates for product returns. Those estimates could change, and as a result, actual results could differ materially from those estimates. In March 2020, the World Health Organization declared the COVID-19 outbreak to be a pandemic. During the period ended June 30, 2022, the Company’s financial results were not significantly affected by the COVID-19 outbreak. The Company has considered all information available as of the date of issuance of these financial statements and the Company is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. The extent to which the COVID-19 outbreak affects the Company’s future financial results and operations will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the outbreak, and current or future domestic and international actions to contain and treat it. For a discussion of risks of COVID-19 relating to the Company’s business, see “Item 1A. - Risk Factors- Risks Related to Our Business- The novel coronavirus global pandemic could adversely impact our business, including our supply chain, clinical trials and commercialization of Mytesi and Canalevia.”
Cash	Cash The Company’s cash on deposit may exceed United States federally insured limits at certain times during the year. The Company maintains cash accounts with certain major financial institutions in the United States. The Company does not have cash equivalents as of June 30, 2022 and December 31, 2021.
Accounts Receivable	Accounts Receivable Accounts receivable is recorded net of allowances for discounts for prompt payment and credit losses. The Company estimates an allowance for credit losses by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. The corresponding expense for the credit loss allowance is reflected in general and administrative expenses. The credit loss allowance was immaterial as of June 30, 2022 and December 31, 2021. In addition, the Company writes off an uncollectible accounts receivable that have a contractual maturity of one year or less when there is information indicating that the counterparty is in severe financial difficulty and there is no realistic prospect of recovery.
Concentrations	Concentrations Cash is the financial instrument that potentially subjects the Company to a concentration of credit risk as cash is deposited with a bank and cash balances are generally in excess of Federal Deposit Insurance Corporation insurance limits. For the three and six months ended June 30, 2022 and 2021, substantially all of the Company’s revenue was derived from the sale of Mytesi. In looking at sales by the Company to distributors whose net revenue percentage of total net revenue was equal to or greater than 10%, for the three and six months ended June 30, 2022, the Company earned Mytesi revenue primarily from two specialty pharmacies located in the United States. For the three and six months ended June 30, 2021, the Company earned Mytesi revenue primarily from two specialty pharmacies in the United States. Revenue earned from each as a percentage of total revenue is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ Six Months Ended ​ ​ June 30, ​ ​ June 30, ​ ​ (unaudited) ​ ​ (unaudited) ​ ​ 2022 2021 ​ 2022 2021 Customer 1 ​ — % 84 % ​ — % 85 % Customer 2 ​ 34 % 11 % ​ 34 % 11 % Customer 3 ​ 49 % — % ​ 53 % — % Customer 4 ​ 10 % — % ​ 5 % — % ​ On September 3, 2021, the Company ended its engagement with Cardinal Health as its exclusive title model customer for commercial sales and fully implemented its limited distribution Specialty Pharmacy model. Cardinal Health continues to provide third-party logistics services for Mytesi. The Company is subject to credit risk from its accounts receivable related to its sales. The Company generally does not perform evaluations of customers' financial condition and generally does not require collateral. As of June 30, 2022 and December 31, 2021, the Company’s significant customers and their related accounts receivable balance as a percentage of total accounts receivable were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ ​ 2022 ​ December 31, ​ ​ (unaudited) ​ 2021 Customer 1 ​ — % ​ 16 % Customer 2 ​ 38 % ​ 37 % Customer 3 ​ 50 % ​ 37 % ​ The Company is subject to concentration risk from its suppliers. The Company sources raw material used to produce the active pharmaceutical ingredient (“API”) in Mytesi from two suppliers and is dependent on a single third-party contract manufacturer for the supply of API in Mytesi and a single third-party contract manufacturer as well for the supply of finished products for commercialization.
Other Risks and Uncertainties	Other Risks and Uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to war, rapid technological change, obtaining second source suppliers, regulatory approval from the FDA or other regulatory authorities, the results of clinical trials and the achievement of milestones, market acceptance of the Company’s product candidates, competition from other products and larger companies, protection of proprietary technology, strategic relationships and dependence on key individuals. Russia-Ukraine War In February 2022, the Russian Federation and Belarus commenced a military action against the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these unaudited condensed consolidated financial statements and the specific impact on the Company’s financial condition, results of operations and cash flows are also not determinable as of the date of these unaudited condensed consolidated financial statements.
Fair Value	Fair Value The Company’s financial instruments include accounts receivable, accounts payable, accrued liabilities, warrant liabilities, equity-linked financial instruments and debt. The recorded carrying amounts of accounts receivable, accounts payable and accrued liabilities reflect their fair value due to their short-term nature. Other financial liabilities are initially recorded at fair value, and subsequently measured at either fair value or amortized cost using the effective interest method. See Note 4 for the fair value measurements.
Fair Value Option	Fair Value Option ASC 825-10, Financial Instruments
Inventory	Inventory ​ Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Cost is initially recorded at the invoiced amount of raw materials or API, including the sum of qualified expenditures and charges in bringing the inventory to its existing condition and location. The Company calculates inventory valuation adjustments when conditions indicate that net realizable value is less than cost due to physical deterioration, usage, obsolescence, reductions in estimated future demand or reduction in selling price. Inventory write-downs are measured as the difference between the cost of inventory and net realizable value. The Company does
Property and Equipment	Property and Equipment Land is stated at cost, reflecting the fair value of the property at July 31, 2017, the date of the Napo merger. Equipment is stated at cost, net of accumulated depreciation. Equipment begins to be depreciated when it is placed into service. Depreciation is calculated using the straight-line method over estimated useful lives ranging between 3 to 10 years. Expenditures for repairs and maintenance of assets are charged to expense as incurred. Costs of major additions and betterments are capitalized and depreciated on a straight-line basis over their estimated useful lives. Upon retirement or sale, the cost and related accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included in the unaudited condensed consolidated statements of operations.
Long-Lived Assets	Long-lived Assets The Company regularly reviews the carrying value and estimated lives of all of its long-lived assets, including property and equipment and definite-lived intangible assets, to determine whether indicators of impairment exist that warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management’s estimate of the asset’s ability to generate positive income from operations and positive cash flow in future periods as well as the strategic significance of the assets to the Company’s business objectives. If the Company determines that an impairment trigger has been met, the Company evaluates the realizability of its long-lived assets (asset group) based on a comparison of projected undiscounted cash flows from use and eventual disposition with the carrying value of the related asset. Any write-downs (which are measured based on the difference between the fair value and the carrying value of the asset) are treated as permanent reductions in the carrying amount of the assets (asset group). Based on this evaluation, the Company believes that, as of each of the balance sheet dates presented, none of the Company’s long-lived assets were impaired. The Company’s had no impairment of long-lived assets as of June 30, 2022 and 2021.
Indefinite-lived Intangible Assets	Indefinite-lived Intangible Assets Acquired IPR&D are intangible assets acquired in the July 2017 Napo merger. Under ASC 805, IPR&D are initially recognized at fair value and classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. During the development period, these assets will not be amortized as charges to earnings; instead, these assets will be tested for impairment on an annual basis or more frequently if impairment indicators are identified. An impairment loss is measured based on the excess of the carrying amount over the asset’s fair value. The Company recorded no impairment in the three and six months ended June 30, 2022 and 2021.
Leases	Leases The Company accounts for its leases in accordance with ASC 842, Leases At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. Because the interest rate implicit in lease contracts is typically not readily determinable, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received. Operating Lease The Company entered into a sublease agreement with Peacock Construction Inc. (“Peacock”), a California corporation, for office space located in San Francisco, California. The term of the sublease began on August 31, 2020 and expired on May 31, 2021. The rent under the sublease is $15,000 per month beginning October 1, 2020, which includes operating expenses and taxes. On October 1, 2020, the Company transitioned its operations from its existing premises to the sublease premises, which the Company expects will serve as its principal administrative headquarters. The Company elected not to apply the recognition requirements to short-term leases, and instead recognize the lease payments in profit or loss on a straight-line basis over the lease term. As a result, there was no right-of-use asset and lease liability In April 2021, the Company entered into an office lease agreement with M & E, LLC, a California Limited Liability Company, to lease approximately 10,526 square feet of office space located in San Francisco, California, inclusive of office space currently covered under the sublease agreement with Peacock. The term of the lease began on September 1, 2021 and will expire on August 31, 2024, unless earlier terminated. The base rent under the lease will be $42,000 monthly for the first 12 months, $43,000 monthly for the next 12 months and $45,000 for the last twelve months. In October 2021, the Company entered into an agreement with Copernico Centrale for the lease of office premises from November 1, 2021 to April 30, 2022, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €10,000 or approximately $10,500. If the contract is not terminated within 12 months, the lease amount will be increased in line with the index of relevant inflation at each annual expiration of the start date of the contract. On January 26, 2022, the lease agreement was amended whereby the term was extended by 20 months from May 1, 2022 to December 31, 2023. All other contract provisions remained the same. In December 2021, the Company entered into an agreement with Arval Service Lease Italia SpA for the lease of two separate vehicles for 48 months expiring on November 30, 2025. Total monthly lease payment amounted to €2,000 or $2,100 payable in advance. The Company elected to include both the lease and non-lease components as a single component and account for it as a lease. The Company also paid a total deposit of €19,000 or approximately $20,000, exclusive of VAT. Early termination of the contracts requires the payment of specified amounts. In January 2022, the Company entered into an agreement with Copernico Centrale for the lease of office premises from March 1, 2022 to December 31, 2023, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €4,000 or approximately $4,200. A similar agreement was entered with the lessor for the lease of premises to be used as office space from November 1, 2022 to December 31, 2023, subject to automatic renewal for subsequent periods until terminated by either party. Base rent amounted to €3,817 or approximately $4,000. If the contracts are not terminated within 12 months, the lease amounts will be increased in line with the index of relevant inflation at each annual expiration of the start date of the contract. In May 2022, the Company entered into an agreement with ALD Automative Italia S.r.l for the lease of one vehicle for 48 months expiring on April 30, 2026. Total monthly lease payment amounted to €833 or approximately $880 payable in advance. The Company elected to include both the lease and non-lease components as a single component and account for it as a lease. The Company also paid a total deposit of €21,000 or approximately $22,000, exclusive of VAT. Early termination of the contracts requires the payment of specified amounts.
Research and Development Expense	Research and Development Expense Research and development expense consists of expenses incurred in performing research and development activities including related salaries, clinical trials and related drug and non-drug product costs, contract services and other outside service expenses. Research and development expense is charged to operating expense in the period incurred.
Clinical Trial Accruals	Clinical Trial Accruals Clinical trial costs are a component of research and development expenses. The Company accrues and expenses clinical trial activities performed by third parties based upon actual work completed in accordance with agreements established with clinical research organizations and clinical sites. The Company determines the costs to be recorded based upon validation with the external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers The Company’s policy typically permits returns if the product is damaged, defective, or otherwise cannot be used when received by the customer if the product has expired. Returns are accepted for product that will expire within three months or that have expired up to one year after their expiration dates. Estimates for expected returns of expired products are based primarily on an ongoing analysis of our historical return patterns. The Company recognizes revenue in accordance with the core principle of ASC 606 or when there is a transfer of control of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. The Company does not adjust the amount of consideration for the effects of a significant financing component if, at contract inception, the expected period between the transfer of promised goods or services and customer payment is one year or less. The Company has elected to treat shipping and handling activities as fulfillment costs. Additionally, the Company elected to record revenue net of sales and other similar taxes. Contracts – Cardinal Health and Other Distributors Effective January 16, 2019, the Company engaged Cardinal Health as its exclusive third-party logistics distribution agent for commercial sales of the Company’s Mytesi product and to perform certain other services which include, without limitation, storage, distribution, returns, customer support, financial support, Electronic Data Interchange (“EDI”) and system access support (the “Exclusive Distribution Agreement”). On September 3, 2021, the Company ended its engagement with Cardinal Health as its exclusive title model customer for commercial sales and fully implemented its limited distribution Specialty Pharmacy model. Cardinal Health continues to provide third-party logistics services for Mytesi. The Company's Canalevia, Neonorm and botanical extract products are primarily sold to distributors, who then sell the products to the end customers. Since 2014, the Company has entered into several distribution agreements with established distributors such as Animart, Vedco, VPI, RJ Matthews, Covetrus, and Stockmen Supply to distribute the Company's animal health products in the United States, Japan, and China. The distribution agreements and the related purchase order together meet the contract existence criteria under ASC 606-10-25-1. The Company sells directly to its customers without the use of an agent. Performance obligations For animal health products sold by the Company, the single performance obligation identified above is the Company’s promise to transfer the Company’s animal products to distributors based on specified payment and shipping terms in the arrangement. Product warranties are assurance-type warranties that do not represent a performance obligation. For the Company’s human health product, Mytesi, the single performance obligation identified above is the Company’s promise to transfer Mytesi to Cardinal Health, based on specified payment and shipping terms as outlined in the Exclusive Distribution Agreement. Transaction price For contracts with Cardinal Health and other distributors, the transaction price is the amount of consideration to which the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi, Canalevia and Neonorm is the Wholesaler Acquisition Cost (“WAC”), net of discounts, returns, and price adjustments. Allocate transaction price For contracts with Cardinal Health and other distributors, the entire transaction price is allocated to the single performance obligation contained in each contract. Revenue recognition For contracts with Cardinal Health and other distributors, a single performance obligation is satisfied at a point in time, upon the free on board (“FOB”) terms of each contract when control, including title and all risks, has transferred to the customer. Disaggregation of Product Revenue Human Sales of Mytesi are recognized as revenue at a point in time when the products are delivered to the wholesaler. Net revenue from the sale of Mytesi were $384,000 and $317,000 for the three months ended June 30, 2022 and 2021, respectively. Net revenue from the sale of Mytesi were $723,000 and $1.3 million for the six months ended June 30, 2022 and 2021. Animal The Company recognized Canalevia product revenues were $87,000 and zero for the three months ended June 30, 2022 and 2021, respectively. Revenues from the sale of Canalevia were $131,000 and zero for the six months ended June 30, 2022 and 2021, respectively. Neonorm revenues of $15,000 and $6,000 for the three months ended June 30, 2022 and 2021, respectively. Revenues from the sale of Neonorm were $35,000 and $39,000 for the six months ended June 30, 2022 and 2021, respectively. Revenues are recognized at a point in time upon shipment, which is when title and control is transferred to the buyer. Sales of Canalevia-CA1, Neonorm Calf and Foal to distributors are made under agreements that may provide distributor price adjustments and rights of return under certain circumstances. Contracts – Specialty Pharmacies Effective October 1, 2020, the Company engaged a private company as its third-party logistics distribution agent for commercial sales of the Company’s Mytesi product. Under the Specialty Product Distribution Agreement, the Company shall supply the products to the private company’s specialty pharmacies, through a designated wholesaler, in such amounts as may be ordered. There is no minimum purchase or inventory requirement. The specialty pharmacies were authorized distributors of record for all National Drug Codes (“NDCs”) of Mytesi. Effective April 20, 2021, the Company engaged another private company as an authorized specialty pharmacy provider of Mytesi. Under the Specialty Pharmacy Distribution and Services Agreement, the private company shall sell and dispense the Mytesi directly ordered from the Company at the agreed price to patients within the territories identified in the agreement. The two contracts with the four specialty pharmacies were combined into one portfolio of contract as they share similar characteristics. Performance obligations The single performance obligation is the Company’s promise to transfer Mytesi to specialty pharmacies, based on specified payment and shipping terms as outlined in the agreements. Transaction price The transaction price is the amount of consideration to which the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi is the WAC, net of estimated discounts, returns, and price adjustments. Allocate transaction price The entire transaction price is allocated to the single performance obligation contained in each contract. Revenue recognition The single performance obligation is satisfied at a point in time, upon the free on board (“FOB”) terms of each contract when control, including title and all risks, has transferred to the customer. Disaggregation of Product Revenue Sales of Mytesi are recognized as revenue at a point in time when products are delivered to the specialty pharmacies. Net revenue from the sale of Mytesi to the specialty pharmacies were $2.4 million and $62,000 for the three months ended June 30, 2022 and 2021, respectively. Net revenue from the sale of Mytesi to the specialty pharmacies were $4.7 million and $237,000 for the six months ended June 30, 2022 and 2021, respectively.
Collaboration Revenue	Collaboration Revenue Revenue recognition for collaboration agreements requires significant judgment. The Company’s assessments and estimates are based on contractual terms, historical experience and general industry practice. Revisions in these values or estimations have the effect of increasing or decreasing collaboration revenue in the period of revision. On September 24, 2018, the Company entered into a Distribution, License and Supply Agreement (“License Agreement”) with Knight Therapeutics ("Knight"). The License Agreement has a term of 15 years (with automatic renewals) and provides Knight with an exclusive right to commercialize current and future Jaguar human health products (including crofelemer, Lechlemer, and any product containing a proanthocyanidin or with an anti-secretory mechanism) in Canada and Israel. Knight forfeited its right of first negotiation for expansion to Latin America. Under the License Agreement, Knight is responsible for applying for and obtaining necessary regulatory approvals in the territory of Canada and Israel, as well as marketing, sales and distribution of the licensed products. Knight will pay a transfer price for all licensed products, and upon achievement of certain regulatory and sales milestones, the Company may receive payments from Knight in an aggregate amount of up to approximately $18 million payable throughout the initial 15-year term of the agreement. The Company did not have any license revenues for the three and six months ended June 30, 2022 and 2021. On June 21, 2022, the Company entered into a License Agreement (“License Agreement”) with SynWorld Technology Corporation (“Synworld”). The License Agreement grants Synworld an exclusive, non-transferable, non-sublicensable license of patents and know-how to significantly improve and/or expand the scope of the Company’s intellectual property rights and to commercialize a canine-specific pharmaceutical product that utilizes Crofelemer as its active drug substance marketed in the United States under the Trademark Canalevia®, Canalevia-CA1 and Canalevia CA-2 (“Product”) for the treatment, prevention, or amelioration of diarrhea in dogs in China, excluding Hong Kong (“Licensee Territory”). Synworld is responsible to prepare, submit and obtain all regulatory approvals for the Product in the Licensee Territory on behalf of, and in the name of the Company (the “Services”). During the Initial Term, Synworld will be solely responsible for all fees and expenses incurred by or on behalf of Synworld with respect to the performance of the Services (“Regulatory Expense”), subject to both parties’ election for the Company to reimburse Regulatory Expenses up to $2.0 million (“Reimbursement Cap”). All Regulatory Expenses in excess of the Reimbursement Cap and any additional fees and expenses incurred thereafter for maintaining the regulatory approvals will be borne by Synworld. As consideration for the license granted, Synworld should make non-refundable cash payments with an aggregate amount of $5.0 million during the initial two-year term of the agreement. The Company did not have any license revenues for the three and six months ended June 30, 2022 and 2021.
Modifications to Liability-classified Instruments	Modifications to Liability-classified Instruments In accounting for debt modifications and exchange transactions, it is the Company’s policy to first determine whether it qualifies as a troubled debt restructuring (“TDR”) pursuant to the guidance provided in ASC 470-60. A debt modification or exchange transaction that is not within the scope of the ASC 470-60 is accounted for under ASC 470-50 to determine if the transaction is a mere modification or an extinguishment. In the three and six months ended June 30, 2021, the Company amended the terms of its October 2020 Purchase Agreement and Exchange Note 2, respectively. In the three and six months ended June 30, 2022, the Company entered into another amendment on the terms of its October 2020 Purchase Agreement (see Note 8).
Modifications to Equity-classified Instruments	Modifications to Equity-classified Instruments ​ In accounting for modifications of equity-classified warrants, it is the Company’s policy to determine the impact by analogy to the share-based compensation guidance of ASC 718, Compensation - Stock Compensation modification is recognized as an expense in the statements of operations to the extent the modified instrument has a higher fair value; however, in certain circumstances, such as when an entire class of warrants is modified, the measured increase in fair value may be more appropriately recorded as a deemed dividend, depending upon the nature of the warrant modification. The Company did not modify any equity-classified warrants in the three and six months ended June 30, 2022 and 2021. In accounting for amendments to preferred stock, it is the Company’s policy to measure the impact by analogy to ASC 470-50 in determining if such an amendment is an extinguishment or a modification. If the amendment results in an extinguishment, the Company follows the SEC staff guidance in ASC 260-10-S99-2 and ASC 470-20. If the amendment results in a modification, the Company follows the model in either ASC 718 or ASC 470-50, depending on the nature of the amendment. The Company did not modify any preferred stock in the three and six months ended June 30, 2022 and 2021.
Stock-based Compensation	Stock-based Compensation The Company's Stock Incentive Plan (see Note 12) provides for the grant of stock options, restricted stock and restricted stock unit awards. The Company measures stock awards granted to employees, non-employees and directors at estimated fair value on the date of grant and recognizes the corresponding compensation expense of the awards, net of estimated forfeitures, over the requisite service periods, which correspond to the vesting periods of the awards. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company issues stock awards with only service-based vesting conditions, and records compensation expense for these awards using the straight-line method. The Company uses the grant date fair market value of its common stock to determine the grant date fair value of options granted to employees, non-employees and directors. The Company measures and recognizes compensation expense for all stock options and restricted stock units (“RSUs”) granted to its employees and directors based on the estimated fair value of the award on the grant date. The Company uses the Black-Scholes valuation model to estimate the fair value of stock option awards. The fair value is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award, on a straight-line basis. The Company believes that the fair value of stock options granted to non-employees is more reliably measured than the fair value of the services received. The determination of the grant date fair value of options using an option pricing model is affected by the Company’s estimated Common Stock fair value and requires management to make a number of assumptions including the expected life of the option, the volatility of the underlying stock, the risk-free interest rate and expected dividends. The Company estimates the fair value of stock options using the Black-Scholes option valuation model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair market value of common stock is based on the closing price of the Company’s common stock as reported on the date of the grant.
Foreign Currency Remeasurement and Translation	Foreign Currency Remeasurement and Translation The functional currency of Napo Therapeutics is Euro. The Company follows ASC 830, Foreign Currency Matters For certain subsidiaries, translation adjustments result from the process of translating the functional currency of subsidiary financial statements into the U.S. Dollar reporting currency. These translation adjustments are reported separately and accumulated in the consolidated balance sheets as a component of accumulated other comprehensive loss.
Comprehensive Loss	Comprehensive Loss For all periods presented, the comprehensive loss was equal to the net loss; therefore, a separate statement of comprehensive loss is not included in the accompanying unaudited condensed consolidated financial statements.
Basic and Diluted Net Loss Per Common Share	Basic and Diluted Net Loss Per Common Share Basic net loss per common share is computed by dividing net loss attributable to common stockholders for the year by the weighted-average number of common shares outstanding during the year. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders for the year by the weighted-average number of common shares, including potential dilutive shares of common stock assuming the dilutive effect of potential dilutive securities. For periods in which the Company reports a net loss, diluted net loss per common share is the same as basic net loss per common share, because the impact of the potential dilutive shares of common stock would be anti-dilutive to the calculation of net loss per common share. Diluted net loss per common share is the same as basic net loss per common share for the three and six months ended June 30, 2022 and 2021.
