Brief summary
This is a randomized, placebo-controlled, double-blind phase I clinical study of anti-SARS-CoV-2 equine immunoglobulin F(ab')2 fragments (INOSARS) to evaluate the safety and antiviral efficacy for the treatment of adult patients with mild COVID-19 and low risk of disease progression.
Interventions
Placebo of saline solution of equal volume and infusion. Content of the infusion bag and tubing will be concealed with opaque covering.
INOSARS is a polyvalent passive immunization based on anti-SARS-CoV-2 immunoglobulin F(ab')2 fragments from hyperimmune equine serum. Inactive ingredients: water for injection, sodium chloride and less than 10% of total protein content.
