This is a Prospective, Randomized, Multi-center, Open label, Phase 1/2 study to Evaluate the Safety and Efficacy of Equine COVID-19 Antiserum [F(ab')2].

BSV has developed Equine COVID-19 antiserum from horse serum for the use in COVID-19 infection. The indication proposed is to provide passive immunization to the COVID-19 infected patient thereby reducing the viral load and prevention of disease progression.

Clinical phase 1 and phase 2 studies have been planned to be conducted. The phase 1 study will be conducted on two dosages to find the safety and tolerability in patients. Based on the results of phase 1 study the phase 2 shall be initiated.
