Brief Summary:
Interventional, randomized, double-blind, placebo-controlled study encompassing 2 development phases (Phase 2 and Phase 3).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| COVID | Drug: mavrilimumab Other: Placebo | Phase 2 Phase 3 |
The Phase 2 portion of the study will evaluate the efficacy and safety of 2 dose levels of mavrilimumab relative to placebo (standard of care) in participants who have tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with x-ray/computed tomography (CT) evidence of bilateral pneumonia and active or recent signs of hyperinflammation (fever or clinical laboratory results indicative of hyper-inflammation). The Phase 3 portion is intended to confirm Phase 2 efficacy and safety findings. In both Phase 2 and Phase 3, participants will be enrolled into 2 cohorts: Cohort 1 will include non-intubated, hospitalized participants who require supplemental oxygen to maintain oxygen saturation (SpO2) ≥ 92% (ie, "non-ventilated" participants); Cohort 2 will include hospitalized participants for whom mechanical ventilation was recently initiated (ie, "ventilated" participants). Following Screening, enrolled participants in each cohort will be randomized 1:1:1 to receive one of 2 mavrilimumab dose levels, or placebo as a single intravenous (IV) infusion (Day 1). Participants will undergo primary study assessments through Day 29 and will be followed for safety through Day 90.

Primary Outcome Measures :
- Cohort 1: Proportion of subjects alive and free of mechanical ventilation at Day 29 [ Time Frame: Day 29 ]
Mechanical ventilation is defined as invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO). Mechanical ventilation status will be evaluated based on the National Institute of Allergy and Infectious Diseases (NIAID) clinical outcome 8-point ordinal scale. Subjects whose clinical outcome has met a NIAID score of 2 will be considered as using mechanical ventilation.
The NIAID is an 8-point ordinal scale of clinical outcomes: 1=death; 2=hospitalized, on invasive mechanical ventilation or ECMO; 3=hospitalized, on non-invasive ventilation or high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5=hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID 19 related or otherwise); 6=hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7=not hospitalized, limitation on activities and/or requiring home oxygen; 8=not hospitalized, no limitations on activities.
- Cohort 2: Mortality rate at Day 29 [ Time Frame: Day 29 ]Mortality rate is defined as the proportion of subjects who have died by Day 29.
Secondary Outcome Measures :
- Cohort 1: Mortality rate at Day 29 [ Time Frame: By Day 29 ]Mortality rate is defined as the proportion of participants who die.
- Cohort 1: Ventilation-free survival by Day 29 [ Time Frame: By Day 29 ]Defined as time from randomization to ventilation or death; subjects still alive will be censored at Day 29.
- Cohort 1: Overall survival by Day 29 [ Time Frame: Day 29 ]Defined as time from randomization to death; subjects still alive will be censored at Day 29.
- Cohort 2: Time to 1-point clinical improvement by Day 29 [ Time Frame: By Day 29 ]Defined as time from randomization to a 1-point improvement on the NIAID 8-point ordinal scale, or discharge from the hospital, whichever comes first. Subjects who die before Day 29 will be censored at Day 30.
