This was a Phase 2, randomized, double-blind, placebo-controlled, parallel-group, multicenter, dose escalation and proof-of-concept study to evaluate the safety and efficacy of razuprotafib, administered 3 times daily (TID) (every 8 hours [Q8H]), in hospitalized subjects with moderate to severe Coronavirus disease 2019 (COVID-19) receiving standard of care therapy. The study was planned to include 2 parts with Part 1 comprising the dose escalation period of the study and Part 2 comprising the proof-of-concept safety and efficacy period of the study.

Other | Summary of Razuprotafib Plasma Concentration | A summary of plasma razuprotafib concentrations for samples collected on Day 1 and 6 in the pharmacokinetic population. All results were summarized descriptively by treatment group. | razuprotafib plasma concentrations 30 and 90 minutes post-dose on Days 1 and 6 | |
Primary | Number and Percent of Subjects Who Were Alive and Free of Respiratory Failure Prior to Day 7 and Day 28 | All results were summarized descriptively by treatment arm and expressed as proportions, along with corresponding 95%CI of the difference between response rates, and p-values using Cochran-Mantel-Haenszel (CMH). The 95% CI will be constructed using the normal approximation method. Respiratory failure was defined as subjects who were on invasive mechanical ventilation; received oxygen delivered by high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20L/min with fraction of delivered oxygen =0.5) noninvasive positive pressure ventilation or extracorporeal membrane oxygenation; or had a clinical diagnosis of respiratory failure (ie, clinical need for 1 of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation).Subjects who died prior to the study timepoint (Day 7 or Day 28) were imputed based on the worst outcome. | Baseline up to Day 7 and Day 28 | |
