Intravenous Zotatifin in Adults With Mild or Moderate COVID-19

This randomized, double-blind, placebo-controlled, dose-escalating study will evaluate the safety and efficacy of zotatifin administered IV to adults with mild or moderate COVID 19. Patients will be randomized to receive zotatifin or placebo in 3 cohorts of 12 patients each. Cohorts will be sequentially enrolled at progressively higher zotatifin dose levels. Study drug will not be administered to patients who are hospitalized. The second dose of study drug will not be administered should a patient progress from mild or moderate COVID-19 to severe COVID-19 prior to or on Day 8. Patients will assess and record their symptoms daily through Day 22 and at follow up (30 days after last infusion) (or at the early termination visit \[if conducted\]) in a paper patient diary using the WHO 9-point ordinal scale for clinical improvement. Other safety and efficacy measures will be assessed according to the Schedule of Procedures on Days 1, 4, 8, 10, 15 (end of treatment visit), and 22, and at follow up (30 days after last infusion). On non-dosing days, study visits will be conducted as home health visits, except for the follow-up visit, which will be conducted as a telephone visit.
