About ARCA biopharmaARCA biopharma is dedicated to developing genetically targeted therapies for heart failure and other cardiovascular disease. The Company's lead product candidate, bucindolol hydrochloride, is an investigational, pharmacologically unique beta-blocker and mild vasodilator being developed for heart failure. ARCA has identified common genetic variations that it believes predict individual patient response to bucindolol, giving it the potential to be the first genetically-targeted heart failure treatment. ARCA is collaborating with Laboratory Corporation of America to develop the companion genetic test for bucindolol. For more information please visit www.arcabiopharma.com.
