About

JINZHEN is a botanical drug that contains eight chemical constituents extracted from plant, mineral and animal origin raw materials. This study is to evaluate the safety and efficacy of JINZHEN Granules for Oral Solution compared to placebo for treatment of mild to moderate COVID-19 outpatients.

Full description

The study is a randomized, double-blind, placebo-controlled, proof of concept study with four groups (low dose treatment group, middle dose treatment group, high dose treatment group, and placebo group). Study eligibility will be assessed during screening. Study participants will be randomized in a 3:1 ratio to receive JINZHEN Granules for Oral Solution or placebo granules for 14 days.

During the 14-day clinical study, participants will be assessed daily at home using e-diary to collect clinical data and in person visit on Day 7 and Day14. All subjects will undergo a series of efficacy, safety, and laboratory assessments. Clinical observation endpoints will be assessed at day 7 and day 14. Interim analysis will be performed to evaluate efficacy and safety of 7-day and 14-day treatment.

20. Participants who plan to receive live attenuated vaccine within 1 month prior to the first administration of the study drug or during the study period.
21. Participants with mild to moderate COVID-19 who would be eligible for another FDA authorized COVID-19 therapeutic.
22. Participants who are on sensitive substrates or substrates of a narrow therapeutic range for major cytochrome P450 and transporters.
23. Other conditions inappropriate for participation in this clinical trial considered by the investigators.
