BROOMFIELD, Colo.--(BUSINESS WIRE)--ARCA biopharma, Inc. (Nasdaq: ABIO), a biopharmaceutical company developing genetically-targeted therapies for atrial fibrillation and other cardiovascular diseases, today announced results of analyses of atrial fibrillation and pharmacogenetic data from the BEST trial, a previously conducted Phase 3 heart failure trial involving Gencaro in 2,708 advanced heart failure patients. Pursuant to their analysis, researchers concluded that Gencaro substantially decreased the risk of new onset atrial fibrillation in a large moderate-to-severe heart failure population, with a risk reduction of 41%. Furthermore, the researchers concluded that patients with a specific genotype (homozygous arginine at beta-1 389) had a 74% risk reduction for new onset atrial fibrillation. Based on a DNA sub-study in the BEST trial, ARCA believes approximately 50% of U.S. population has this specific genotype.
