Brief Summary:
A phase 2/3, randomized, double blind, placebo-controlled study to evaluate the efficacy and the safety of ABX464 in treating inflammation and preventing acute respiratory failure in patients aged ≥65 and patients aged ≥18 with at least one additional risk factor who are infected with SARS-CoV-2 (the MiR-AGE study).

Condition or disease Intervention/treatment Phase
COVID-19 Drug: ABX464 Drug: Placebo Phase 2 Phase 3

Detailed Description:

This phase 2/3 study will evaluate the efficacy and safety of ABX464 50mg QD (oral capsule), on treating inflammation and preventing acute respiratory failure in patients infected with SARS-CoV-2.

Eligible patients will be randomized according to a 2:1 ratio into 2 treatment cohorts as follows:

  • Standard of Care + Placebo cohort: 344 patients
  • Standard of Care + ABX464 50mg QD: 690 patients

Study design:

The study will consist of 2 periods:

  • Treatment phase: randomized patients will be treated for 28 days
  • Safety follow-up phase of 14 days after which the End of Study visit (EOS) will be performed.

Primary Outcome Measures :
  1. Rate of patients with no invasive or non-invasive mechanical ventilation (IMV and NIV, respectively), but excluding simple nasal/mask oxygen supplementation, and who are alive [ Time Frame: at the end of the 28-day treatment period ]

Secondary Outcome Measures :
  1. Rate of patients hospitalized [ Time Frame: 28-day treatment period ]
  2. Percentage of patients reporting each severity rating on a 7-point ordinal scale [ Time Frame: 28-day treatment period ]
    7-point ordinal scale is defined as Not hospitalized, no limitations on activities; Not hospitalized, limitation on activities; Hospitalized, not requiring supplemental oxygen; Hospitalized, requiring supplemental oxygen; Hospitalized, on non-invasive ventilation or high flow oxygen devices; Hospitalized, on invasive mechanical ventilation or ECMO; Death

  3. Change from enrolment in inflammatory markers in plasma and in immune phenotype and assessment of cell-activation markers in PBMCs [ Time Frame: at each study visit during the 28-day treatment period ]
  4. Rate of patients requiring oxygen supplementation [ Time Frame: 28-day treatment period ]
  5. Time to hospitalization [ Time Frame: 28-day treatment period ]
  6. Time to assisted ventilation and oxygen supplementation [ Time Frame: 28-day treatment period ]
  7. Change from baseline in microRNA-124 levels [ Time Frame: at each study visit during the 28-day treatment period ]
  8. Change from baseline in CRP, Troponin I & T and D-dimer [ Time Frame: at each study visit during the 28-day treatment period ]
  9. SARS-CoV-2 viral load [ Time Frame: at each study visit during the 28-day treatment period ]
    Nasopharyngeal sample and/or in blood

  10. Number and rates of participants with Treatment Emergent Adverse Event [ Time Frame: 28-day treatment period ]
