What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are PKN605, or Placebo. The registry lists allocation as randomized. A randomly assigned, compared with a dummy treatment, participant-and investigator-blinded study to measure the how well it works in reducing atrial fibrillation burden as well as the safety, tolerability and pharmacokinetics of PKN605 in participants with atrial fibrillation
They plan to enroll about 165 people at 34 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
Official title (unrewritten)
