About ARCA biopharmaARCA biopharma is dedicated to developing genetically-targeted therapies for cardiovascular diseases. The Company's lead product candidate, Gencaro TM (bucindolol hydrochloride), is an investigational, pharmacologically-unique beta-blocker and mild vasodilator being developed for the prevention of atrial fibrillation in patients with heart failure. ARCA has identified common genetic variations in the cardiovascular system that it believes interact with Gencaro’s pharmacology and may predict individual patient response to Gencaro, giving it the potential to be the first genetically-targeted treatment for the prevention of atrial fibrillation. ARCA is collaborating with Laboratory Corporation of America to develop the companion genetic test for Gencaro. For more information, please visit www.arcabiopharma.com. Safe Harbor Statement This press release may contain "forward-looking statements" for purposes of the safe harbor provided by the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, the ability of genetic variations to predict individual patient response to Gencaro; the potential for Gencaro to be the first genetically-targeted atrial fibrillation prevention treatment; the projected increase in prevalence of atrial fibrillation; and, the projected increase in the size of the atrial fibrillation drug market in developed countries. Such statements are based on management's current expectations and involve risks and uncertainties. Actual results and performance could differ materially from those projected in the forward-looking statements as a result of many factors, including, without limitation, the risks and uncertainties associated with: the Company's financial resources and whether they will be sufficient to meet the Company's business objectives and operational requirements; the protection and market exclusivity provided by the Company’s intellectual property; risks related to the drug discovery and the regulatory approval process; and, the impact of competitive products and technological changes. These and other factors are identified and described in more detail in ARCA’s filings with the SEC, including without limitation the Company’s annual report on Form 10-K for the year ended December 31, 2010 and subsequent filings.
