Danegaptide (GAP-134) is a small dipeptide gap junction modifier, developed by Wyeth and Zealand Pharma. Danegaptide works by re-establishing of gap junction intercellular communications in adjacent cardiomyocytes, thus reversing cardiac conduction slowing and electrical heterogeneity thought to be responsible for arrhythmias. In a canine model of acute sterile pericarditis, Danegaptide significantly reduced AF duration and overall AF burden. Danegaptide was investigated in phase 2 clinical trial in patients with ST-segment elevation myocardial infarction (STEMI). It was found that administrations danegaptide to patients with STEMI did not improve myocardial salvage, and development of the drug was discontinued.
