Official title

A PHASE 1, OPEN-LABEL, NON-RANDOMIZED STUDY TO INVESTIGATE THE SAFETY AND PK FOLLOWING MULTIPLE ORAL DOSES OF PF-07321332 (NIRMATRELVIR)/RITONAVIR IN ADULT PARTICIPANTS WITH COVID-19 AND SEVERE RENAL IMPAIRMENT EITHER ON HEMODIALYSIS OR NOT ON HEMODIALYSIS

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to learn about the side effects (safety) of the study medicine PF-07321332 (nirmatrelvir)/ritonavir for the treatment of mild to moderate COVID-19 infection in adults with severe renal impairment. The study will also look at the amounts of study drug in your blood. There will be 24 participants in this study; 12 of them will have severe renal impairment and not be on hemodialysis and 12 of them will be on hemodialysis. All participants in this study will take PF-07321332 (nirmatrelvir)/ritonavir by mouth for 5 days. During this time, they will have to collect blood samples to measure the study drug levels in their blood. After taking the study drug for 5 days, the participants will have follow-up visits for about another 28 days for a total of about 34 days in the study. The study team will check how each participant is doing during regular visits at the study clinic.
