Overview
We are a biopharmaceutical company principally focused on developing genetically-targeted therapies for cardiovascular diseases. Our lead product candidate, Gencaro™ (bucindolol hydrochloride), is a pharmacologically unique beta-blocker and mild vasodilator that we are evaluating in a clinical trial for the treatment of atrial fibrillation, or AF, in patients with heart failure and left ventricular systolic dysfunction, or HFREF. We have identified common genetic variations in receptors in the cardiovascular system that we believe interact with Gencaro’s pharmacology and may predict patient response to the drug.
We are testing this hypothesis in a Phase 2B/3 clinical trial of Gencaro, known as GENETIC-AF. We are pursuing this indication for Gencaro because data from a prior Phase 3 HF trial of Gencaro in 2,708 heart failure, or HF, patients, or the BEST trial, which suggested that Gencaro may be successful in reducing or preventing AF.
In April 2015, the U.S. Food and Drug Administration, or FDA, designated as a Fast Track development program the investigation of Gencaro™ for the prevention of atrial fibrillation/atrial flutter in a genetically targeted heart failure population (heart failure patients with reduced left ventricular ejection fraction).
Fast Track drug development designation was included in the FDA Modernization Act of 1997, or FDAMA, as a formal process to enhance interactions with the FDA during drug development. A drug development program with Fast Track designation is eligible for consideration for some or all of the following programs for expediting development and review: scheduled meetings to seek FDA input into development plans, priority review of the New Drug Application, or NDA, the option of submitting portions of an NDA for review prior to submission of the complete application and potential accelerated approval.
AF is a disorder in which the normally regular and coordinated contraction pattern of the heart’s two small upper chambers, or the atria, becomes irregular and uncoordinated. The irregular contraction pattern associated with AF causes blood to pool in the atria, predisposing the formation of clots potentially resulting in stroke.
AF is considered an epidemic cardiovascular disease. The estimated number of individuals with AF globally in 2010 was 33.5 million. According to the 2015 American Heart Association report on Heart Disease and Stroke Statistics, the estimated number of individuals with AF in the United States in 2010 ranged from 2.7 million to 6.1 million people. AF increases the risk of stroke and may also contribute to worsening heart failure. The approved therapies for the treatment or prevention AF have certain disadvantages in HFREF patients, such as toxic or cardiovascular adverse effects, and most of the approved drugs for AF are contra indicated or have warnings in their prescribing information for such patients. We believe there is an unmet medical need for new AF treatments that have fewer side effects than currently available therapies and are more effective, particularly in HFREF patients.
GENETIC-AF is a Phase 2B/3 multi-center, randomized, double-blind clinical trial comparing the safety and efficacy of Gencaro to an active comparator, the beta-blocker Toprol XL (metoprolol succinate), in HFREF patients with a current or recent history of paroxysmal (AF episodes lasting 7 days or less) or persistent AF who have a beta-1 389 arginine homozygous genotype, the genotype we believe responds most favorably to Gencaro. The primary endpoint of GENETIC-AF, time to recurrent symptomatic AF/atrial flutter, or AFL, or all-cause mortality, will be measured over a twenty-four week period after a patient has established a normal heart rhythm.
We believe data from the BEST trial indicate that Gencaro may have a genetically regulated effect in reducing or preventing AF, whereas we believe the therapeutic benefit of Toprol XL does not appear to be enhanced in patients with this genotype. A retrospective analysis of data from the BEST trial shows that the entire cohort of patients in the BEST trial treated with Gencaro had a 41% reduction in the risk of new onset AF (time-to-event) compared to placebo (p = 0.0004). In the BEST DNA substudy, patients with the beta-1 389 arginine homozygous genotype experienced a 74% (p = 0.0003) reduction in risk of AF when receiving Gencaro, based on the same analysis. The beta-1 389 arginine homozygous genotype was present in about 47% of the patients in the BEST pharmacogenetic substudy, and we estimate it is present in about 50% of the U.S. general population.

Table of Contents
We have created an adaptive design for GENETIC-AF and are seeking to enroll approximately 200 HFREF patients in the Phase 2B portion of the study who have recently experienced at least one episode of paroxysmal or persistent AF and who have the beta-1 389 arginine homozygous genotype that we believe responds most favorably to Gencaro. In addition to measuring the primary endpoint of recurrent symptomatic AF/AFL or all-cause mortality, an additional efficacy measure in the Phase 2B portion of GENETIC-AF will be AF burden, defined as a patient’s percentage of time in AF per day, regardless of symptoms. At least 150 patients in the Phase 2B portion of the trial will have either a newly or previously implanted Medtronic device that measures and records AF burden. The GENETIC-AF Data Safety Monitoring Board, or DSMB, will analyze certain data from the Phase 2B portion of the trial and recommend, based on a comparison to our pre-trial statistical assumptions, whether the trial should proceed to Phase 3 and seek to enroll an additional 420 patients. The DSMB will make their recommendation based on analysis of certain trial data after 200 patients have completed 24 weeks of follow-up, the period for measuring the primary end-point of the trial. The DSMB interim analysis will focus on available data regarding the primary end point, AF/AFL event rates, AF burden, and safety. Should the DSMB interim analysis conclude that the interim data is consistent with pre-trial statistical assumptions and indicates potential for achieving statistical significance for the Phase 3 endpoint, the DSMB may recommend that the study proceed to Phase 3. The DSMB may also recommend changes to the study design before the trial proceeds to Phase 3, or it may recommend that the study not proceed to Phase 3. Based on the DSMB recommendation, and other factors, including input from the trial’s Steering Committee, the Company will make the final determination on the trial’s development steps. The full Phase 2B/3 trial is designed for 90 percent power at a p-value of less than 0.01 significance level to detect a 25 percent reduction in the risk of AF recurrence or death in patients in the Gencaro arm compared to patients in the Toprol XL arm.
In consultation with the GENETIC-AF Steering Committee, we implemented amendments to the trial protocol in March 2015 which we believe may expand the eligible target population, increase the patient screening and enrollment rate, and simplify trial procedures. We have undertaken these protocol amendments because patient enrollment in the trial has not met our original projections. Under the revised protocol, patients in sinus rhythm who have experienced symptomatic AF in the past 120 days are now eligible for inclusion in the trial, as are patients with AF episodes lasting 7 days or less, or paroxysmal AF. Previously, these patients were not eligible to be enrolled in the trial. We believe this expanded target population has the potential to improve trial screening and enrollment rates and could broaden the potential commercial market for Gencaro, should it achieve regulatory approval in the future. The amendments to the protocol do not fundamentally alter or impact the original endpoints of the clinical trial. Based on the projected impact of the expanded patient population and the current enrollment rate, we now project that the enrollment of 200 patients for the Phase 2B portion of the trial may be completed by the end of 2016, with the DSMB interim analysis finishing in the first half of 2017. We do not yet know how these protocol changes will impact enrollment or if our new enrollment projections will prove to be accurate. We met with the FDA, prior to implementation, to confirm the acceptability of the amendments to the protocol and received no objections.
Our GENETIC-AF clinical trial of Gencaro requires a companion diagnostic test to identify the patient’s receptor genotype. We have an agreement with Laboratory Corporation of America, or LabCorp, to provide the companion diagnostic test and services to support our GENETIC-AF trial. LabCorp has developed the genetic test and obtained an Investigational Device Exemption, or IDE, from the United States Food and Drug Administration, or the FDA, for the companion diagnostic test which is being used in our GENETIC-AF clinical trial.
Medtronic, Inc., or Medtronic, a leader in medical technologies to improve the treatment of chronic diseases, including cardiac rhythm disorders, is collaborating with us on the GENETIC-AF trial. Under the collaboration with Medtronic, ARCA is conducting a substudy that includes continuous monitoring of the cardiac rhythms of at least 150 patients enrolled during the Phase 2B portion of the trial. The collaboration is administered by a joint ARCA-Medtronic committee. Medtronic uses its proprietary CareLink System to collect and analyze the cardiac rhythm data from the implanted Medtronic devices and the data will be used by the DSMB as part of the interim analysis. Medtronic will support the reimbursement process for U.S. patients enrolled in the Phase 2B portion, and will provide financial support of unreimbursed costs for a certain number of U.S. patients in the Phase 2B portion up to a certain maximum amount per patient. If GENETIC-AF proceeds to Phase 3, we will seek to enroll an additional 100 patients, with Medtronic devices for monitoring and recording AF burden, in the substudy. Medtronic will provide the agreed upon CareLink System cardiac rhythm data collection and analysis for the Phase 3 portion of the substudy and support the reimbursement process.
We have been granted patents in the United States, Europe, and other jurisdictions for methods of treating AF and HF patients with Gencaro based on genetic testing, which, if we are granted patent term extension, may provide market exclusivity for these uses of Gencaro into approximately 2030 in the United States and Europe.
To support the continued development of Gencaro, in June 2015, we completed a private placement that raised approximately $34 million of net proceeds as additional funds for the Phase 2B portion of the GENETIC-AF trial and to support our ongoing operations. We are seeking to enroll approximately 200 HFREF patients in the Phase 2B portion of the GENETIC-AF trial, and we anticipate that our current cash and cash equivalents will be sufficient to fund our operations, at our projected cost structure, through the end of 2017. However, in light of the significant uncertainties regarding clinical development timelines and costs for developing drugs such as

Gencaro, we may need to raise a significant amount of additional capital due to changing circumstances that may cause us to consume capital significantly faster or slower than we currently anticipate. We have based these estimates on assumptions that may prove to be wrong, and we could exhaust our available financial resources sooner than we currently anticipate. If GENETIC-AF proceeds to Phase 3, we will be required to raise additional funds prior to completion of the Phase 3 portion.

On June 16, 2015, we issued to the selling stockholders named below an aggregate of 42,021,579 shares of common stock and warrants to purchase an additional 16,808,632 shares of common stock in a private placement. The shares of common stock being offered by the selling stockholders are those issued to the selling stockholders and those issuable to the selling stockholders upon exercise of the warrants. For additional information regarding the issuance of the common stock and the warrants, see “Prospectus Summary—Private Placement” above. We are registering the shares of common stock in order to permit the selling stockholders to offer the shares for resale from time to time. The selling stockholders include entities affiliated with Venrock Healthcare Capital Partners, entities affiliated with New Enterprise Associates, funds managed by Franklin Advisers, Inc., entities affiliated with RA Capital Management, Tekla Life Sciences Investors, Capital Ventures International and entities affiliated with DAFNA LifeScience, L.P..
The table below, including the footnotes thereto, lists the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Exchange Act of 1934 and the rules and regulations thereunder) of the shares of common stock held by each of the selling stockholders based in part on information provided to us by the selling stockholders. The second column lists the number of shares of common stock beneficially owned by the selling stockholders, based on their respective ownership of shares of common stock and warrants, as of June 30, 2015, assuming exercise of the warrants held by each such selling stockholder on that date without taking account of any limitations on exercise set forth therein.
The third column lists the shares of common stock being offered by this prospectus by the selling stockholders and does not take into account any limitations on exercise of the warrants set forth therein.
In accordance with the terms of a registration rights agreement with the holders of the common stock and the warrants, this prospectus generally covers the resale of the sum of (i) the shares of common stock issued to the selling stockholders and (ii) the maximum number of shares of common stock issuable upon exercise of the warrants determined as if the outstanding warrants were exercised in full (without regard to any limitations on exercise contained therein) as of the trading day immediately preceding the date this registration statement was initially filed with the SEC. Because the exercise price of the warrants may be adjusted, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus.
The fourth column assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus. However, because the selling stockholders may sell all or some of their shares under this prospectus from time to time, or in another permitted manner, we cannot assure you as to the actual number of shares that will be sold by the selling stockholders. The percentage of shares owned after the offering is based on 63,219,990 shares of our common stock outstanding as of June 30, 2015, which includes the outstanding shares of common stock offered by this prospectus, plus the number of shares of our common stock issuable within 60 days of June 30, 2015 upon the exercise of any warrants, or other convertible securities, held by the selling stockholders.
Under the terms of the warrants, a selling stockholder may not exercise the warrants to the extent (but only to the extent) such selling stockholder and any of its affiliates would beneficially own a number of shares of our common stock which would exceed 9.9% of our outstanding common stock, provided, however, that if the outstanding shares of common stock held by such selling stockholder and its affiliates, together, without giving effect to such selling stockholder’s warrants, exceeds 9.9% of our outstanding common stock, prior to the exercise of any warrants, then such selling stockholder may not exercise the warrants to the extent (but only to the extent) such selling stockholder and any of its affiliates would beneficially own a number of shares of our common stock that would exceed 19.9% of our outstanding common stock. RA Capital Healthcare Fund, L.P., RA Capital Management, LLC, Blackwell Partners LLC – Series A, and Peter Kolchinsky are considered one entity for the purposes of calculating the 9.9% maximum percentage described in the preceding sentence. The number of shares in the second column does not reflect these limitations. The selling stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

We are registering the shares of common stock issued to the selling stockholders and the shares of common stock issuable upon exercise of the warrants to permit the resale of these shares of common stock by the selling stockholders from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock.
The selling stockholders may sell all or a portion of the shares of common stock held by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, pursuant to one or more of the following methods:
| • | on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale; |
| • | in the over-the-counter market; |
| • | in transactions otherwise than on these exchanges or systems or in the over-the-counter market; |
| • | through the writing or settlement of options, whether such options are listed on an options exchange or otherwise; |
| • | ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; |
| • | block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; |
| • | purchases by a broker-dealer as principal and resale by the broker-dealer for its account; |
| • | an exchange distribution in accordance with the rules of the applicable exchange; |
| • | privately negotiated transactions; |
| • | short sales made after the date this registration statement is declared effective by the SEC; |
| • | broker-dealers may agree with a selling securityholder to sell a specified number of such shares at a stipulated price per share; |
| • | a combination of any such methods of sale; and |
| • | any other method permitted pursuant to applicable law. |
The selling stockholders may also sell shares of common stock under Rule 144 promulgated under the Securities Act, if available, rather than under this prospectus. In addition, the selling stockholders may transfer the shares of common stock by other means not described in this prospectus. If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved).
In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.
The selling stockholders may pledge or grant a security interest in some or all of the warrants or shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

To the extent required by the Securities Act and the rules and regulations thereunder, the selling stockholders and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed or paid to broker-dealers.
Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
There can be no assurance that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part.
The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.
We will pay all expenses of the registration of the shares of common stock pursuant to the stock purchase agreement, estimated to be $330,000 in total, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act in accordance with the securities purchase agreements or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related securities purchase agreements or we may be entitled to contribution.
Once sold under the registration statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.
