Brief summary
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.
Detailed description
Part 1 was to be a 2-step dose escalation that included approximately 60 subjects. Part 1, Step 1 was to include 30 subjects, and Part 1, Step 2 was to include 30 subjects. Part 1 was designed to primarily focus on safety; however, efficacy data was to be collected and analyzed as well. Despite the Data Review Committee (DRC) recommendation to continue the study, after completion of Part 1, Step 1, the Sponsor elected to discontinue the study due to business-related reasons. Recruitment challenges and slow site startup led to delays in completing the study in a practical timeframe, and were the primary reasons to discontinue the study. No further subjects were recruited after Part 1, Step 1 completion. A full analysis of the data from Part 1, Step 1 was conducted and is presented in this report. Part 1, Step 2 and Part 2 was not conducted.
Interventions
Up to 3 daily dose levels of Razuprotafib Subcutaneous Solution will be evaluated. Doses will be administered subcutaneously three times daily (Q8H) for 7 days.
Matched vehicle-controlled placebo solution will be administered subcutaneously three times daily (Q8H) for 7 days

Participants in this population were analyzed according to the treatment group to which they were assigned at randomization. Note: The overall number of participants analyzed represents the total number of participants in each treatment group for the ITT Population. Participants who had post-baseline data on Days 7 and 28 (or death) were included in the analyses.

Number of Participants in Each Category of the NIAID 8-point Ordinal Scale at Day 7 and Day 28
Summary of number and percent of subjects in each category (ie, categories 1 to 8) of the NIAID 8-Point Ordinal Scale at baseline, Day 7 and Day 28. The NIAID 8-point ordinal scale includes the following grades: 1. Death; 2. Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3. Hospitalized, on noninvasive ventilation or high-flow oxygen devices; 4. Hospitalized, requiring supplemental oxygen; 5. Hospitalized, not requiring supplementation 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; and 8. Not hospitalized, no limitations on activities.
Time frame: Baseline, Day 7, and Day 28
Population: Intent-to-Treat (ITT) Population: The ITT Population was defined as all subjects randomized.

Time to Reach Grade 6, 7, or 8 on the NIAID 8-Point Ordinal Scale
The clinical status of the participants was assessed within 1 hr prior to each dose of study drug, using the NIAID 8-point ordinal scale until Day 28. After the treatment period, clinical status will be assessed once daily until Day 18, unless discharged. If the subject is discharged alive prior to Day 28, clinical status was assessed at the post-treatment observation period telephone visits only. Grade 6=hospitalized, not requiring oxygen and no longer requires ongoing medical care; Grade 7 = not hospitalized, limitation on activities and/or requiring home oxygen; and Grade 8 = not hospitalized, no limitations on activities.
Time frame: From Screening through the end of the study (up to 28 days)
Population: Intent-to-Treat (ITT) Population: The ITT Population was defined as all subjects randomized. Participants in this population were analyzed according to the treatment group to which they were assigned at randomization. Note: The overall number of participants analyzed represents the total number of participants in each treatment group for the ITT Population. The number of participants included in the analyses had post-baseline data through the end of the study.
