Asundexian is a Factor XIa inhibitor developed by Bayer to prevent stroke.^[1]

Clinical trial(s)

Asundexian efficacy and safety in patients have been evaluated in two clinical trial programs: phase IIb PACIFIC and phase III OCEANIC.^[2] In the phase IIb PACIFIC clinical trial programs, asundexian consistently showed no difference in bleeding rate compared with placebo^[3]^[4] and reduced the risk of bleeding compared with apixaban.^[5] All three trials in the programs were not powered to show efficacy of asundexian.^[2] However, a phase III trial, OCEANIC-AF, was stopped due to a "lack of efficacy." The remaining active study OCEANIC-STROKE was recommended to continue as planned. Bayer is reevaluating the design of the OCEANIC-AFINA based on the findings of the OCEANIC trial.^[6]
