The interim analysis conducted on Jan 7,2021 was based on 60 patients in Proxalutamide arm and 35 patients in the control arm. The percentage of hospitalization,admission to ICU,mechanical ventilation requirement and death was 1.7% vs. 17.1%,0% vs. 8.6%,0% vs. 5.7% and 0%,vs. 2.9% in Proxalutamide and placebo arms respectively.
