NCT05977101

Brief Summary

This is a randomized, double-blind, placebo-parallel intervention clinical study that will include approximately 72 healthy subjects based on inclusion and exclusion criteria. Patients who met the inclusion and exclusion criteria were randomly assigned to one of three different cohorts. Subjects in each cohort were randomly assigned in a ratio of 5:1 to two parallel dosing groups, one of which served as the control group. Each cohort was given either an experimental drug or a placebo nasal spray at different doses and intervals, and blood was collected on an empty stomach before the first dose, and left nasal swabs and throat swabs were collected for immunotoxicity and drug concentration testing. 14 days after the last dose, subjects will return to the study Center for blood samples, left nasal swabs, and throat swabs to be collected for drug concentration, immunotoxicity, and safety laboratory indicators (routine blood and biochemistry). To evaluate the safety and tolerability of MY-586 SARS-CoV-2 Neutralizing Antibody nasal spray in healthy subjects, and to evaluate its serum concentrations and nasal and pharyngeal swab concentrations by comparing the test results of different cotillaries.
