简要总结
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)]
- To examine lipid mediators, specifically thromboxane A2, prostaglandin D2, F2-isoprostane and/or their metabolites in convalescent subjects after treatment.
- To assess the efficacy of Ramatroban administered during the acute illness in preventing/mitigating subsequent development of long COVID / PASC
