Brief summary

Part 1 of this trial enrolled 30 patients to receive Auxora (formerly CM4620) in a 2:1 randomized, open label trial of patients with severe and critical COVID-19 pneumonia. Part 2 of this study randomized 284 patients and was a randomized, double blind, placebo-controlled (RCT) study that evaluated the efficacy, safety, and the pharmacokinetic profile of Auxora in patients with severe COVID-19 pneumonia. The number of patients with an imputed PaO2/FiO2 \>200 randomized into the study was capped at 26. Another 258 patients with a PaO2/FiO2 ≤200 were enrolled. Patients with an estimated PaO2/FiO2 of 75-200 were stratified to ensure balanced randomization between the Auxora and placebo arms. Subgroup analyses were performed to explore how time to recovery is influenced by baseline variables and to evaluate the treatment effect at different levels of each of these variables. The dose of Auxora was 2.0 mg/kg (1.25 mL/kg) administered at 0 hour, and then 1.6 mg/kg (1 mL/kg) at 24 hours and 1.6 mg/kg (1 mL/kg) at 48 hours from the SFISD. The dose of placebo was 1.25 mL/kg administered at 0 hour and then 1 mL/kg at 24 hours and 1 mL/kg at 48 hours from the SFISD. Remdesivir, corticosteroids and convalescent plasma were allowed. The infusion of Auxora / Placebo started within 12 hours from the time the patient or LAR provided informed consent. Efficacy analyses will be presented by treatment group (Auxora vs Placebo) based on the Efficacy Analysis Set of the imputed PaO2/FiO2 ≤200 subgroup, except where it is specified otherwise. The statistical analysis approach was designed to assess the significance of the primary and first secondary endpoint using the Benjamini and Hochberg method to control the overall trial level alpha level.

Interventions

DRUGAuxora (Part 1)

Auxora will be given at 2.0 mg/kg (1.25 mL/kg) on Day 1 and then 1.6 mg/kg (1.0 mL/kg) on Days 2 and 3. All doses of Auxora will be administered intravenously (IV) over 4 hours.

DRUGStandard of Care (Part 1)

Patients received standard of care

DRUGAuxora (Part 2)

Auxora will be given at 2.0 mg/kg (1.25 mL/kg) on Day 1 and then 1.6 mg/kg (1.0 mL/kg) on Days 2 and 3. All doses of Auxora will be administered intravenously (IV) over 4 hours.

Placebo will be given at 2.0 mg/kg (1.25 mL/kg) on Day 1 and then 1.6 mg/kg (1.0 mL/kg) on Days 2 and 3. All doses of Placebo will be administered intravenously (IV) over 4 hours.
