Brief Summary:

Phase II & Phase III:

This is a pragmatic, adaptive, randomized, multicenter phase II/III study evaluating IFX-1 for the treatment of COVID-19 related severe pneumonia. The study consists of two parts: Phase II, an open-label, randomized, 2-arm phase evaluating best supportive care (BSC) + IFX-1 (Arm A) and BSC alone (Arm B); and Phase III, a double-blind, placebo-controlled, randomized phase comparing standard of care (SOC) + IFX-1 (Arm A) versus SOC + placebo-to-match (Arm B)

Condition or disease Intervention/treatment Phase
Severe COVID-19 Pneumonia Drug: SOC + IFX-1 Drug: SOC + Placebo Phase 2 Phase 3

Detailed Description:

The phase II and Phase III portions enrolls patients subsequently.

1st patient was enrolled in the phase III portion on 1st October 2020.
