Bayer AG NABayer initiates Phase II trial of its GIRK4 inhibitor for atrial fibrillation, a positive clinical development.

Bayer has announced the initiation of a global Phase II clinical trial evaluating BAY 3670549, an investigational highly selective GIRK4 inhibitor, as a potential new treatment for atrial fibrillation, the most common sustained cardiac arrhythmia affecting over 60 million people worldwide. The randomized, double-blind, placebo-controlled study will assess the drug's efficacy, safety, and pharmacokinetics in adult patients with AFib who require electrical cardioversion. Positive data from the Phase I first-in-human study supported advancing the compound, which emerged from Bayer's strategic research alliance with the Broad Institute of MIT and Harvard. If successful, BAY 3670549 could offer an alternative to electrical cardioversion, the current gold standard for restoring normal heart rhythm.
