Summary

Phase II/Phase III study to evaluate the safety and efficacy of Ramatroban 75 mg tablet against Placebo in subjects hospitalized for pneumonia due to SARS-CoV-2 infection. Approximately 324 eligible subjects will be randomized in a 1:1 ratio to one of the two treatment groups. Group I: Ramatroban 75 mg tablet + Standard of care; Group II: Placebo + Standard of care. Phase 2 Primary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To assess the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Phase 3 Primary Objective: To evaluate the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Long COVID \[Follow-up Phase- Objectives- (Phase 2 \& 3)\] 1. To examine lipid mediators, specifically thromboxane A2, prostaglandin D2, F2-isoprostane and/or their metabolites in convalescent subjects after treatment. 2. To assess the efficacy of Ramatroban administered during the acute illness in preventing/mitigating subsequent development of long COVID / PASC
