| COVID-19 Immunodeficiency | Drug: Paxlovid 5 days Drug: Paxlovid 10 days Drug: Veklury | Phase 2 |
This is a randomized, controlled, factorial, superiority trial to evaluate the viral efficacy of DAA (nirmatrelvir/r) + DAA (remdesivir)∞ versus nirmatrelvir/r alone and of 5 days versus 10 days of nirmatrelvir/r in immunocompromised patients diagnosed with asymptomatic or mild to moderate COVID-19.
The primary objective is to assess whether (i) a combination antiviral therapy of two DAA (nirmatrelvir/r + remdesivir)∞ And/or (ii) an increase in nirmatrelvir/r duration from 5 to 10 days improves viral efficacy by decreasing the SARS-CoV-2 positivity rate by real time RT-PCR (CT<32) in nasopharyngeal swabs at D10.
Patients will be eligible if they are immunocompromised, have confirmed asymptomatic SARS-CoV-2 infection or mild to moderate COVID-19, regardless of symptoms onset, provided that they have no contra-indication to any of the study drugs.
A total of 256 patients will be included in France and Switzerland.

| Experimental: Nirmatrelvir/r 5 days alone |
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. Other Name: Nirmatrevlir/ritonavir |
| Experimental: Nirmatrelvir/r 10 days alone |
Drug: Paxlovid 10 days
Nirmatrelvir/r 300mg/100 mg bid will be given for 10 days, orally.
Other Name: Nirmatrevlir/ritonavir |
| Experimental: Nirmatrelvir/r 5 days + remdesivir s.d |
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. Other Name: Nirmatrevlir/ritonavir Drug: Veklury Remdesivir "flash", 200mg, intravenous. Remdesivir (marketed by Gilead under de brand name Veklury®) is indicated in patients with pneumonia requiring supplemental oxygen (inpatients), as well as in outpatients who are at increased risk of progressing to severe COVID-19. The mode of action characterize remdesivir as a direct-acting antiviral compound.
