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

Detailed Description:
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) and have x-ray/computerized tomography (CT) evidence of bilateral pneumonia, active or recent fever, and 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.
