ARCA biopharma granted patent for methods of treating heart failure patients with bucindolol based on genetic testing

ARCA biopharma, Inc. (Nasdaq: ABIO), a biopharmaceutical company developing genetically targeted therapies for heart failure and other cardiovascular diseases, today announced that the U.S. Patent and Trademark Office (USPTO) has issued a patent on methods of treating heart failure patients with bucindolol based on genetic testing. The patent (USP# 7,678,824) entitled “Methods for Treatment with Bucindolol Based on Genetic Targeting,” provides protection in the United States for this novel approach to treating patients with heart failure, one of the largest health care problems in the United States and the rest of the world. ARCA had previously announced the notice of allowance of this patent. Industry sources estimate that approximately 5.7 million Americans have heart failure and nearly 670,000 new patients are diagnosed annually. In addition, heart failure is the underlying reason for approximately 12 to 15 million annual visits to physicians, 6.5 million annual hospital days and over $37 billion in direct and indirect healthcare costs in the United States.

“Methods for Treatment with Bucindolol Based on Genetic Targeting”

“We are obviously pleased with the USPTO’s issuance of this patent which we believe will extend our pharmacogenetic intellectual property protection around bucindolol and, if approved for marketing, provide Gencaro market exclusivity into 2025,” said Michael R. Bristow, President and Chief Executive Officer of ARCA. “Chronic heart failure continues to be a major health care problem, and among the challenges to improving care is the uncertainty of patient responses to drug treatment. We believe that a new heart failure therapy that includes a simple test to identify a substantial subpopulation of patients more likely to benefit has the potential to help alleviate some of the problems encountered with the current standard of practice.”

On March 25, 2010, ARCA submitted a revised clinical study protocol for review under the U.S. Food and Drug Administration’s (FDA) Special Protocol Assessment (SPA) process for the design of a clinical trial to assess the safety and efficacy of Gencaro in approximately 3,200 patients with chronic heart failure who have the genotype that appears to respond most favorably to Gencaro. An SPA is an agreement with the FDA that the proposed trial protocol design, clinical endpoints and statistical analyses are acceptable to support regulatory approval. Any proposed trial protocol must be reviewed and agreed upon with the FDA and the final trial protocol may be significantly different from the Company’s SPA submission. If ARCA obtains sufficient funding and FDA approval of the SPA, ARCA currently expects it could begin the proposed clinical trial approximately one year after such funding and approval. The FDA has previously designated as a Fast Track development program the investigation of Gencaro for the reduction of cardiovascular mortality and cardiovascular hospitalizations in a genotype-defined heart failure population.
