CTRI/2020/05/024959- Eligible patients were randomized (2:1) to arm A (best supportive care + Itolizumab) and arm B (best supportive care). The primary outcome of interest was reduction in all-cause mortality 30 days after enrolment. Thirty-six patients were screened, 5 were treated as first dose sentinels and the rest were randomized, whilst 4 patients were considered screen failures. Two patients in the Itolizumab treatment arm discontinued prior to receiving the first dose and were replaced. At the end of 1 month, there were 3 deaths in arm B, and none in arm A (p= 0.0296). At the end of the follow-up period, more patients in Arm A had improved SpO2 without increasing FiO2 (p=0.0296), improved PaO2 (p=0.0296), and reduction in IL-6 (43 pg/ml vs 212 pg/ml; p=0.0296) and tumor necrotic factor-α (9 pg/ml vs 39 pg/ml; p=0.0253) levels. Itolizumab was generally safe and well tolerated, and transient lymphopenia (11 patients in Arm A) and infusion reactions (7 patients) were the commonly reported treatment related safety events. These encouraging results indicate that larger clinical trials are warranted to establish the role of Itolizumab in controlling immune hyperactivation in COVID-19.
