Design outcomes

Primary

Measure	Time frame
Main Objective: The primary objective is to compare the clinical efficacy of XAV-19 to that of placebo in patients with COVID-19.;Secondary Objective: The secondary objectives are: - to compare the change in clinical parameters (fever, respiratory rate, shortness of breath, thoracic pain, SpO2, supplemental O2) in patients treated with XAV-19 to that in patients treated with Placebo, - to compare the length of hospital stay of patients treated with XAV-19 to that of patients treated with Placebo, - to compare the viral status of patients treated with XAV-19 to that of patients treated with Placebo, - to compare the safety profile in patients with COVID-19 treated with XAV-19 to that in patients treated with Placebo;Primary end point(s): The primary endpoint is the proportion of patients with an aggravation of COVID-19 within 8 days after treatment. The aggravation is defined as a worsening of the score of at least 1 point on the WHO 7-point ordinal scale compared to the score on the WHO-7 ordinal scale at randomization.;Timepoint(s) of evaluation of this end point: Within 8 days after treatment.	—

Secondary

Measure	Time frame
Secondary end point(s): The secondary endpoints are: • Change in clinical parameters between randomization and Day 3, 5, 8 and 15: fever (>38°C), respiratory rate, SpO2, supplemental O2, • Change in severity, on Common Terminology Criteria of Adverse Events (CTCAE) scale, between randomization and Day 3, 5, 8 and 15: shortness of breath and thoracic pain (See Appendix 12.2), • Duration of patient’s requirement in supplemental O2, • Duration of aggravation • Length of hospital stay, • Clinical status at Day 3 and Day 15 using the WHO 7-point ordinal scale for COVID-19, • Viral status: RT-PCR for SARS-CoV-2 (positive/negative) at randomization and on Day 8 or at the end of follow-up, whichever comes first • Viral load (if local practice enables it): RT-qPCR for SARS-CoV-2 at randomization and on Day 8 or at the end of follow-up, whichever comes first • Proportion of patients referred to ICU between randomization and Day 3, 5, 8 and 15, • Proportion of patients with need for mechanical ventilation at randomization and at Day 3, 5, 8 and 15, • Eight- and 15-day survival rates, defined by the crude proportion of patients still alive 8 or 15 days after randomization • Safety parameters (i.e. adverse events, hypersensitivity or allergy, white and red blood cells, liver enzymes, creatinine);Timepoint(s) of evaluation of this end point: Between randomization and Day 3, 5, 8 and 15.	—
