ARCA biopharma Announces Third Quarter 2015 Financial Results and Provides Business Update

GENETIC-AF Trial Evaluating Gencaro as a Potential Treatment for Atrial Fibrillation

Interim Analysis of Phase 2B Efficacy Data Planned for the First Half of 2017

Westminster, CO, November 12, 2015 ARCA biopharma, Inc. (Nasdaq: ABIO), a biopharmaceutical company developing genetically-targeted therapies for cardiovascular diseases, today reported financial results for the quarter ended September 30, 2015, and provided a business update.

“This has been a productive quarter as we continue enrollment in the GENETIC-AF trial evaluating Gencaro as a potential treatment for atrial fibrillation,” commented Dr. Michael Bristow, ARCA’s President and CEO. “We currently have 58 sites in the United States and Canada recruiting patients for the trial, with all of the sites now operating under the revised trial protocol, which expanded the target patient population. We expect the DSMB interim analysis of Phase 2B efficacy data to occur in the first half of 2017.”

Third Quarter 2015 Summary Financial Results

Cash and cash equivalents totaled $41.5 million as of September 30, 2015, compared to $15.4 million as of December 31, 2014. The Company believes that its current cash and cash equivalents will be sufficient to fund its operations, at its projected cost structure, through at least the end of 2017. ARCA had approximately 9.0 million outstanding shares of common stock as of September 30, 2015.

Research and development (R&D) expense for the three months ended September 30, 2015 was $1.7 million compared to $1.3 million for the corresponding period of 2014, an increase of approximately $0.4 million. R&D expense for the nine months ended September 30, 2015 was $5.2 million compared to $4.0 million for the corresponding period of 2014, an increase of approximately $1.1 million. The increase in R&D expense in the three and nine month periods ended September 30, 2015 is primarily due to the increased clinical expense of the GENETIC-AF clinical trial. The Company expects R&D expense in 2015 to be higher than 2014 as it activates new clinical sites and enrolls additional patients in the GENETIC-AF clinical trial and incurs incremental costs associated with transitioning to the protocol amended in the first quarter of 2015.

General and administrative (G&A) expense for the three months ended September 30, 2015 was $1.1 million compared to $1.0 million for the corresponding period in 2014. G&A expense

for the nine months ended September 30, 2015 was $3.1 million compared to $3.0 million for the corresponding period in 2014. ARCA expects that G&A expense in 2015 will be higher than in 2014 as the Company increases administrative activities to support our GENETIC-AF clinical trial.
Total operating expense for the three months ended September 30, 2015 was $2.8 million compared to $2.3 million for the corresponding period in 2014. Total operating expense for the nine months ended September 30, 2015 was $8.3 million compared to $7.1 million for the corresponding period in 2014. The increase in total operating expense for three and nine month periods ended September 30, 2015 is primarily due to the increase in R&D expense due to the increased clinical expense of the GENETIC-AF clinical trial.

Net loss was $2.8 million, or $0.31 per share, for the third quarter of 2015 and $8.3 million, or $1.54, for the nine months ended September 30, 2015, compared to $2.3 million, or $0.76 per share, for the third quarter of 2014 and $7.1 million, or $2.44 per share, for the nine months ended September 30, 2014.

Key Accomplishments

 Continued implementation of a previously announced protocol amendment for GENETIC-AF, which expanded the trial’s target population.

 Additional investigative clinical sites were approved, trained and began adopting the revised protocol, with all of the clinical sites now operating under the revised protocol.

There are currently 58 clinical trial sites in the United States and Canada. The Company anticipates that the trial will enroll patients at approximately 65 sites for the Phase 2B portion of GENETIC-AF. The Company believes the DSMB interim analysis could be finished in the first half of 2017. Although all of the clinical sites are now operating under the revised protocol, the Company does not yet know how the protocol changes will impact enrollment or if its enrollment projections will prove to be accurate.

GENETIC-AF Trial Phase 2B Projected Timeline

 Revised protocol distributed to participating clinical trial sites March 2015

 GENETIC-AF Trial Investigators meeting and training May

 First trial sites operating under revised protocol May

– Approximately 65 clinical trial sites active in U.S. & Canada Q4

– Completion of Enrollment for Phase 2B DSMB Interim Analysis YE 2016

– DSMB Interim Analysis Decision 1H 2017

The Company’s forecast of the time periods to achieve these milestones is a forward-looking statement and involves risks and uncertainties, and actual results are likely to vary as a result of a number of factors, including the factors discussed in “Risk Factors” in the Company’s periodic SEC filings.

GENETIC-AF Clinical Trial

GENETIC-AF is a Phase 2B/3, multi-center, randomized, double-blind clinical trial comparing the safety and efficacy of Gencaro to Toprol-XL (metoprolol succinate) for the treatment of atrial fibrillation (AF) in patients with heart failure and left ventricular systolic dysfunction (HFREF patients). The primary endpoint of GENETIC-AF is time to symptomatic AF/atrial flutter (AFL). ARCA is enrolling only HFREF patients with the genetic variant of the cardiac beta-1 adrenergic receptor, which the Company believes responds most favorably to Gencaro, the 389 arginine homozygous genotype (ADRB1 Arg389Arg). GENETIC-AF has an adaptive design, under which the Company initiated the trial as a Phase 2B trial seeking to enroll approximately 200 patients. The GENETIC-AF Data Safety Monitoring Board (DSMB) will analyze certain data from the Phase 2B portion of the trial and recommend, based on a comparison to the pre-trial statistical assumptions, whether the trial should proceed to Phase 3 and seek to enroll an additional 420 patients.

Atrial Fibrillation (AF)

Atrial fibrillation, the most common sustained cardiac arrhythmia, is considered an epidemic cardiovascular disease and a major public health burden. 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. Hospitalization rates for AF increased by 23% among U.S. adults from 2000 to 2010 and hospitalizations account for the majority of the economic cost burden associated with AF.

About ARCA biopharma

ARCA biopharma is dedicated to developing genetically-targeted therapies for cardiovascular diseases. The Company’s lead product candidate, GencaroTM (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator being developed for atrial fibrillation. ARCA has identified common genetic variations that it believes predict individual patient response to Gencaro, giving it the potential to be the first genetically-targeted atrial fibrillation prevention treatment. ARCA has a collaboration with Medtronic, Inc. for support of the GENETIC-AF trial. For more information please visit www.arcabiopharma.com.
