Summary

The overall purpose of the trial is to evaluate the efficacy and safety of possible combination antiviral therapy direct antiviral agents (remdesivir + nirmatrelvir/r) versus the reference monotherapy (nirmatrelvir/r alone) and to assess the efficacy and safety of increasing the nirmatrelvir/r course from 5- to 10 days in immunocompromised patients diagnosed with asymptomatic or mild to moderate Coronavirus Disease 2019 (COVID-19).

Conditions

Interventions

DRUG

Paxlovid 5 days

Nirmatrelvir/r 300mg/100 mg bid will be given for 5 days, orally. Nirmatrelvir/r is a combination of two molecules: nirmatrelvir which is a protease inhibitor (against 3CL) and ritonavir which has a booster role. Nirmatrelvir/r (marketed by Pfizer under the brand name Paxlovid®) is indicated for the treatment of COVID-19 in adults who do not require supplemental oxygen and who are at increased risk for progressing to severe COVID-19.

DRUG

Paxlovid 10 days
