Summary

The purpose of this study is to estimate the relative bioavailability (rBA) of nirmatrelvir/ritonavir oral powder in 3 different food vehicles relative to the Paxlovid® tablets under fasted condition in healthy adult participants, and to estimate the effect of food on the rBA of the nirmatrelvir/ritonavir oral powder formulation. The study will also assess the safety, tolerability, and palatability of nirmatrelvir/ritonavir oral powder in healthy adult participants.
