Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
The FDA conducted an advisory committee review regarding the approvability of rivaroxaban for reduction of stroke and systemic embolization in patients with non-valvular atrial fibrillation on September 8th, 2011.

Non Inferiority Margin
An upper bound of the 95% CI of the hazard ratio was set at 1.38 by the FDA to establish non-inferiority. In no subgroup did the comparison come near the non-inferiority margin, and non-inferiority was clearly observed in all treatment subgroups and in all forms of analysis.
Primary Endpoint
The primary endpoint was stroke0 and systemic embolization. The efficacy in the trial was driven by a reduction in hemorrhagic stroke and systemic embolization.
Secondary Endpoints
There were fewer non-fatal myocardial infarctions in the Rivaroxaban group.
