Summary

This is a multicenter, randomized, double-blind, placebo-controlled, add-on Phase III clinical study.

Based on the "Diagnosis and Treatment Protocol for COVID-19 Pneumonia (Trial 10th edition)" and according to the results of phase I and Phase II clinical studies, one dose group and one placebo group were used in this experiment. The experimental group was add-on experimental drugs for basic treatment and the control group was add-on placebo for basic treatment. The clinical study was led by the First Affiliated Hospital of the Chinese People's Liberation Army, and 1320 adult subjects with mild and medium COVID-19 infection were enrolled in the First Affiliated Hospital of the Chinese People's Liberation Army, the Second Affiliated Hospital of the Chinese People's Liberation Army, the Special Medical Center of the Air Force, and the Third People's Hospital of Shenzhen. A ratio of 1 to 1 was randomly assigned to the experimental or placebo groups.Subjects should have tested positive for COVID-19 nucleic acid in a laboratory and developed at least one symptom of SARS-CoV-2 within 96 hours prior to medication. The administration schedule was on day 1 of the trial (intravenous infusion of Meplazumab or placebo once in the morning of D0; The dosage was 0.2 mg/kg. If the 12 common clinical symptoms of SARS-CoV-2 infection are not relieved.the first administration of D7, an additional dose of 0.2 mg/kg is given based on the body weight of the subjects.

BIOLOGICAL

Meplazumab foe injection

Meplazumab is a humanized anti-CD147 immunoglobulin 2 (IgG2) monoclonal antibody which is expected to block the binding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein to the human host-cell-expressed CD147, thereby blocking entry of SARS-CoV-2 into human tissue. This expectation is based on in vitro functional studies using Vero E6 cells infected with SARS-CoV-2 that demonstrated effective meplazumab mediated virus gene copy number inhibition upwards of 90% as evaluated by quantitative polymerase chain reaction. Meplazumab may also inhibit COVID-19 associated cytokine storm syndrome based on inhibition of the pro inflammatory factor Cyclophilin A host-cell CD147 interaction.
