Multicenter Randomized Double-blind Placebo-controlled Study to Investigate Azvudine in Symptomatic Adults With COVID-19 at Increased Risk of Progressing to Severe Illness
Study Details
Study Description
Brief Summary
To investigate whether treatment with Azvudine reduces the risk of severe illness or death in patients who are at a potential risk of progressing to severe COVID-19 infection.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 2/Phase 3 |
Detailed Description
The study is designed as a randomized, parallel, double-blind, placebo-controlled trial, in which all participants will be randomized to a test group or control group in a 1:1 ratio.
The test group will be given Azvudine in combination with conventional therapy excluding anti-viral therapy and observed for efficacy. The control group will be given placebo in combination with conventional therapy excluding anti-viral therapy and observed for efficacy.
Test Group will recruit 548 participants who will be given Azvudine + conventional therapy other than antiviral*5 mg/day, oral, up to 7 days (1 mg/tablet).
Control Group will recruit 548 who will be given Placebo + conventional therapy other than antiviral* 5 tablets/day, oral, up to 7 days.

Outcome Measures
Primary Outcome Measures
- Proportion of COVID-19-related critical illness or all-cause death within 28 days. [28 days]
Proportion of COVID-19-related critical illness or all-cause death within 28 days. COVID-19-related critical illness is defined as: a patient with an SpO2 of 90% to 95% requiring high-flow oxygen inhalation with a fraction of inspired oxygen (FiO2) not less than 60% or requiring non-invasive ventilation with a FiO2 not less than 60%; or requiring mechanical ventilation or ECMO for organ support.
Secondary Outcome Measures
- Incidence rates of Azvudine-related adverse events and serious adverse events [28 days]
Incidence rates of Azvudine-related adverse events and serious adverse events
- Duration of COVID-19-related symptoms [14 days]
Duration of COVID-19-related symptoms
- All-cause death [6 months]
All-cause death
- COVID-19 viral load in pharyngeal swabs [D1, D3, D7]
COVID-19 viral load in pharyngeal swabs
- Days of hospitalization and ICU stay [28 days]
Days of hospitalization and ICU stay
