Brief summary

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.

Detailed description

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.

Interventions

DRUGmQFPD

The dosage of mQFPD is 8 capsules three times a day for 14 consecutive days. It does not need to be consumed with food. It is best taken at least 30 minutes before OR at least 60 minutes after meals, in the morning, noon and evening. Accidentally missed doses will not need to be taken at a later time but will be recorded in a daily diary.

DRUGorganic brown rice

The dosage of mQFPD is 8 capsules three times a day for 14 consecutive days. It does not need to be consumed with food. It is best taken at least 30 minutes before OR at least 60 minutes after meals, in the morning, noon and evening. Accidentally missed doses will not need to be taken at a later time but will be recorded in a daily diary.

Secondary

MeasureTime frameDescription
LDH14 daysA secondary exploratory objective will be to evaluate COVID-19 severity among subjects in each of the two medication arms, compared with placebo, as ascertained by comparing the LDH of baseline laboratory data with end-of-treatment labs or on hospital admission labs (for hospitalized patients).
Mid-turbinate SARS CoV-2 Viral Load14 daysA secondary exploratory objective will be to evaluate COVID-19 severity among subjects in each of the two medication arms, compared with placebo, as ascertained by changes in the SARS CoV-2 viral loads among mid-turbinate nasal swabs taken on days 0, 7 and 14.
Symptom Severities14 daysSymptom severity was assessed via a daily questionnaire across Days 0-14, where participants rated their symptoms on a scale of 0 (none or absent) to 3 (severe). A composite measure was created for each day, based on the 12 symptoms most commonly associated with COVID-19 (fever, fatigue, muscle aches, shortness of breath, shortness of breath upon exertion, cough, sore throat, stuffy nose, runny nose, loss of taste, loss of smell, headache) by summing the total symptom severities for those symptoms. Higher symptom severities indicates a worse outcome. The minimum and maximum were: 0 to 30, respectively.
Symptom Count14 daysSymptom severity was assessed via a daily questionnaire across Days 0-14, where participants rated their symptoms on a scale of 0 (none or absent) to 3 (severe). A composite measure was created for each day, based on the 12 symptoms most commonly associated with COVID-19 (fever, fatigue, muscle aches, shortness of breath, shortness of breath upon exertion, cough, sore throat, stuffy nose, runny nose, loss of taste, loss of smell, headache), and counting the total number of symptoms present.

The INR is a result of a blood test that measures how long it takes for blood to clot, also known as the prothrombin time (PT). The INR is calculated by comparing the PT to the mean normal prothrombin time (MNPT). Higher INR is thought to indicate liver dysfunction.

A secondary exploratory objective will be to evaluate COVID-19 severity among subjects in each of the two medication arms, compared with placebo, as ascertained by changes in the SARS CoV-2 viral loads among mid-turbinate nasal swabs taken on days 0, 7 and 14.

Prothrombin Time

A secondary exploratory objective will be to evaluate COVID-19 severity among subjects in each of the two medication arms, compared with placebo, as ascertained by comparing the Prothrombin Time of baseline laboratory data with end-of-treatment labs or on hospital admission labs (for hospitalized patients).

Symptom Count

Symptom severity was assessed via a daily questionnaire across Days 0-14, where participants rated their symptoms on a scale of 0 (none or absent) to 3 (severe). A composite measure was created for each day, based on the 12 symptoms most commonly associated with COVID-19 (fever, fatigue, muscle aches, shortness of breath, shortness of breath upon exertion, cough, sore throat, stuffy nose, runny nose, loss of taste, loss of smell, headache), and counting the total number of symptoms present.

Symptom Severities

Symptom severity was assessed via a daily questionnaire across Days 0-14, where participants rated their symptoms on a scale of 0 (none or absent) to 3 (severe). A composite measure was created for each day, based on the 12 symptoms most commonly associated with COVID-19 (fever, fatigue, muscle aches, shortness of breath, shortness of breath upon exertion, cough, sore throat, stuffy nose, runny nose, loss of taste, loss of smell, headache) by summing the total symptom severities for those symptoms. Higher symptom severities indicates a worse outcome. The minimum and maximum were: 0 to 30, respectively.
