Bayer AG BAYRY announced that it has initiated a phase I study, which is evaluating its investigational highly selective GIRK4 inhibitor, BAY 3670549, for the treatment of patients with atrial fibrillation (AFib).
The double-blind, placebo-controlled first-in-human dose escalation study will evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of BAY 3670549 in healthy participants.
AFib is a common heart rhythm disorder that affects around 60 million people across the world. AFib is a notable risk factor for stroke and heart failure.
Per management, the current standard for treating acute AFib episodes is electric cardioversion (ECV). However, the process remains challenging as it requires sedation or anesthesia to safely deliver an electrical shock to the patient’s heart in order to restore its normal sinus rhythm.
BAY 3670549 has the potential to help control the electrical activity of cardiomyocytes in patients with AFib.
The successful development of BAY 3670549, should strengthen Bayer’s cardiovascular portfolio.
BAYRY Stock Performance
Year to date, shares of Bayer have rallied 36.7% against the industry’s decline of 3.9%.

BAYRY's Encouraging Pipeline Progress
Bayer is making good pipeline progress with some clinical milestones expected later in 2025. Bayer has also made some notable mergers and acquisitions to diversify and boost its portfolio of drug candidates.
The company plans to launch new drugs — elinzanetant, a hormone-free treatment for menopause symptoms, and acoramidis, a drug for the treatment of a certain form of heart disease. In February 2025, acoramidis was granted regulatory approval in the EU under the brand name Beyonttra.
Bayer had acquired marketing rights to the cardiovascular candidate acoramidis in Europe from BridgeBio BBIO. The rights were acquired from Eidos Therapeutics Inc., BridgeBio International GmbH and BridgeBio Europe B.V.
Bayer has expanded its pipeline in new modalities to include competencies in cell therapy through the acquisition of BlueRock and in gene therapy through the acquisition of AskBio.
Bayer, together with its subsidiaries, BlueRock and AskBio, is developing preclinical and clinical cell and gene therapies for treating various disorders, including congestive heart failure and Parkinson's disease, among others.
