Study participants will be assigned to one of two groups, either placebo or mQFPD. Participants will be screened and consented remotely. Both groups will receive blood draws at days 1 and 14, and will be sent study medication directly to their home from the investigational pharmacy. Baseline and end-of-study laboratory draws will be done at home via mobile phlebotomy. Adverse events and symptoms scores will be monitored by entry into a daily diary along with regular phone calls with the study coordinators.~At the end of the study, safety will be assessed by laboratory measures and adverse event reporting.
This is a multi-center, randomized, double-blind, placebo-controlled clinical trial to evaluate a 21-herb formula named modified Qing Fei Pai Du Tang (mQFPD) to treat COVID-19-positive outpatients with mild-to-moderate symptoms assigned to self-quarantined and home management. This the study aims to establish the safety and feasibility of the use of mQFPD vs placebo in 66 total subjects. Subsequent trials will evaluate other therapeutics as well as the efficacy of mQFPD in a larger study population.
