Recruiting at 9 sites Phase 2 Atrial Fibrillation

Atrial Fibrillation study: BAY

Official title A Study to Test How Well BAY 3670549 Works and How Safe it is in Patients With Atrial Fibrillation

ClinicalTrials.gov ID: NCT07625215

What this study is testing

What is BAY 3670549?

An investigational intravenous medicine being studied for atrial fibrillation.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study compares BAY 3670549 to a placebo to determine how well it works, how safe it is, how well people tolerate it, and how the body processes the drug.
Who it's for
Adults with atrial fibrillation who need a procedure called electrical cardioversion.
What's involved
Participants receive a single IV infusion of either BAY 3670549 or a placebo and are monitored to see if their heart rhythm returns to normal. If it does not, the planned electrical cardioversion can still be performed.
Time commitment
The study lasts up to two months, with visits for the infusion, monitoring, and follow‑up assessments.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug.

Who can take part

Ages 18 to 85

You may be able to join if

  • Participant must be 18 to 85 years of age inclusive, at the time of signing the informed consent.

  • Known severe valvular heart disease (e.g., severe mitral regurgitation, severe aortic stenosis)
  • Patients with NYHA Class ≥ III heart failure, or with active management of acute heart failure decompensation on treatment day.
