Relative Bioavailability Study of Nirmatrelvir/Ritonavir Oral Powder Relative to the Commercial Tablets and Estimation of the Effect of Food on Bioavailability of the Nirmatrelvir/Ritonavir Oral Powder in Healthy Participants.

Biological Availability Clinical Trial

Official title:
A PHASE 1, OPEN-LABEL, RANDOMIZED, SINGLE DOSE, CROSSOVER STUDY TO ESTIMATE THE RELATIVE BIOAVAILABILITY OF NIRMATRELVIR (PF-07321332) /RITONAVIR ORAL POWDER IN 3 DIFFERENT FOOD DELIVERY VEHICLES RELATIVE TO THE NIRMATRELVIR (PF-07321332) /RITONAVIR COMMERCIAL TABLETS UNDER FASTED CONDITIONS, AND THE EFFECT OF FOOD ON RELATIVE BIOAVAILABILITY OF NIRMATRELVIR (PF-07321332) /RITONAVIR ORAL POWDER IN HEALTHY ADULT PARTICIPANTS

Clinical Trial 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.
