Overview
Brief Summary
This is a multicenter, randomized, double-blind, placebo-parallel-controlled phase II clinical trial. It is designed to evaluate the efficacy, safety, tolerability, and pharmacokinetic (PK) profile of SHEN26 capsules in Chinese patients with mild to moderate COVID-19.
Detailed Description
Eligible patients with mild to moderate COVID-19 will be randomized in a 1:1:1 ratio to SHEN26 low dose group (200 mg), SHEN26 high dose group (400 mg), and placebo group, with 30 patients in each group.
