Brief summary

Randomized, Parallel Group, Active Controlled Trial

Detailed description

This is a Multi-Centric, Open label, Two Arm Randomized, Phase 2 Study. All eligible patients entering into the study will be randomized in 2:1 ratio to receive the treatment A (Best supportive care + Itolizumab) / B (Best supportive care) respectively. Each patient will undergo the treatment based on their assigned treatment for a month along with battery of tests that includes, but not limited to, cytokines and chemokine, along with recording of TLC; DLC, ANC, ALC; Platelet count; S. creatinine; T.Bilirubin; morning Vitals -pulse, BP, RR; Temperature, PaO2/FiO2, MAP, GCS. As Itolizumab is an investigational drug, the benefit to COVID-19 patients experiencing complications such as Cytokine Release Syndrome is not known. However, findings from this study may be beneficial to the society at a large at the National and International Level.

Interventions

DRUGItolizumab IV infusion

First dose of 1.6 mg/kg dose iv infusion, , investigator discretion to continue with 1.6 mg/kg dose every 2 weeks or 0.8 mg/kg weekly regimen up to 4 weeks. BSC: similar to Arm B

DRUGBest supportive care (BSC)

Best supportive care (BSC) included drugs like antivirals, antibiotics, Hydroxychloroquine, oxygen therapy, LMWH, Steroids, Vitamins and Zinc
