On August 12, 2020, Cytodyn requested that the Food and Drug Administration grant an Emergency Use Authorization for leronlimab for mild to moderate COVID-19 based on data from the Phase 2 CD10 study (NCT04343651). In this study, patients were randomized to receive weekly doses of 700 mg leronlimab or placebo, both of which were administered via subcutaneous injection. Top-level results of the study showed that, in patients with Total Clinical Symptom Scores of ≥ 4 at baseline (higher scores equate to poorer health state), at Day 3, more subjects treated with leronlimab reported improvement in total clinical symptom score compared to the placebo group (90% on leronlimab arm vs. 71% on placebo). The EUA request was disclosed in an investment community conference call that will be available until September 12, 2020.

• Leronlimab is a humanized IgG4 antibody targeting C-C chemokine receptor type 5.
