NCT05321394

Brief Summary

The study aims at assessing the non-inferiority of tixagevimab plus cilgavimab and nirmatrelvir plus ritornavir vs. sotrovimab (reference standard due to the wider evidence gathered on its efficacy) on COVID-19 progression in a real-life setting of outpatients aged at least 50 years at an early stage of the disease. The progression of COVID-19 disease (hospitalization, need for supplementary oxygen therapy at home, death) within 14 days of randomisation is the composite outcome variable on which the calculation of the sample size is based. Based on available data regarding the reduction in the number of hospitalisations and medical visits with the use of sotrovimab at an early-stage of COVID-19, a disease progression of 1% has been estimated in the reference arm. 3% delta margin was considered clinically relevant, taking into account both the estimates of disease progression in the study population in absence of early treatment (7%, based on national data) and the efficacy of the reference standard. Therefore, 1095 participants will be randomly assigned in an equal ratio between the reference standard and each of the other two experimental arms (1:1:1). Randomization will be computer-generated in permuted blocks with a stratification based on site.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 50 years
  • Informed consent by the subject or legally authorized representative

  • Peripheral oxygen saturation ≥ 94% on room air and not requiring supplemental oxygen
  • Onset of symptom is no more than 4 days prior to the study drug administration. Onset time of symptom is defined as the time when the patient experienced the presence of at least one of the following (but not limited to) SARS-CoV-2 infection-associated symptom (FDA, September 2020): nasal obstruction or congestion, cough, fever \> 37.3 °C, sore throat, body pain or muscle pain, headache, loss of taste or smell, nausea or vomiting, diarrhoea

You may not qualify if:

  • Previously or currently hospitalized or requiring hospitalization
  • Respiratory distress with respiratory rate ≥ 25 breaths/min
  • Heart rate ≥ 125 beats per minute
  • Peripheral oxygen saturation ≤ 93% on room air at sea level
  • Known allergies to any of the components used in the formulation of the interventions
  • Severe renal impairment (eGFR \<30 mL/min)
  • Severe hepatic impairment (Child-Pugh Class C)
  • Co-administration with drugs highly dependent on CYP3A for clearance and for which elevated concentrations are associated with serious and/or life-threatening reactions
  • Co-administration with potent CYP3A inducers
  • Hemodynamic instability requiring use of pressors within 24 hours of randomization
  • Suspected or proven serious, active bacterial, fungal, viral, or other infection (besides COVID-19) that could potentially lead to hospitalization in within 30 days
  • Any co-morbidity requiring surgery within 7 days or that is considered life-threatening within 90 days
  • History of a positive SARS-CoV-2 test prior to the one serving as eligibility for this study
  • Other investigational intervention for SARS-CoV-2 prophylaxis within 30 days before dosing
  • Previous treatment with a SARS-CoV-2 specific monoclonal antibody
  • +6 more criteria
