EPIC-Peds: A Study to Learn About the Study Medicine Called PF-07321332 (Nirmatrelvir)/Ritonavir in Patients Under 18 Years of Age With COVID-19 That Are Not Hospitalized But Are at Risk for Severe Disease

Phase 3
Recruiting
Conditions
COVID-19
Interventions
Registration Number
NCT05261139
Lead Sponsor
Pfizer
Brief Summary

The purpose of this clinical trial is to learn about the safety, pharmacokinetics (pharmacokinetics helps us understand how the drug is changed and eliminated from your body after you take it), and efficacy (how well a study treatment works in the study) of the study medicine (called nirmatrelvir/ritonavir) for potential treatment of coronavirus disease 2019 (COVID-19).

The study medicine will be given to patients under 18 years of age with COVID-19 that are not hospitalized but are at risk for severe disease.
