Overview
Brief Summary
The purpose of this study is to document the safety of taking traditional Chinese medicine (TCM) in patients with COVID-19 and to gain information to determine whether a study with TCM can be conducted. The study will test a traditional Chinese medicine that has been made into a granule formulation called Xuanfei Baidu Granules.
Detailed Description
Xuanfei Baidu granules (XFBD) is a 13 medicinal traditional Chinese medicine (TCM) prescription developed by Dr. Zhang Boli, a member of Chinese Academy of Engineering, and his team, and used in Wuhan, China, during the initial outbreak of SARS-CoV2. Based on TCM theory, the 13 medicinals used mainly consist of heat-clearing and toxin-removing medicinals to reduce fever and clear viruses; cough-suppressing and phlegm-transforming medicinals to thin and clear the phlegm; and lung-diffusing and pant-calming to soothe the tracheal smooth muscle and relieve shortness of breath. Another unique quality is one of the medicinals helps to dissipate stasis and dissolves blood clots, providing a mild anticoagulant effect. Before the widespread usage of TCM, nationwide China saw a progression of disease of about 10% of their mild and moderate cases while during the period with the TCM utilization, the percentage dropped to 2-5% depending on the hospital. Overall, they saw an improvement of clinical symptoms. Due to the challenges of the rapidly evolving outbreak, these are clinical observations and not evidence from a controlled study. The purpose of this initial pilot study is to document the safety of taking a TCM in patients with COVID-19 and to gain information to determine whether a study with TCM can be conducted in the US. The study will test a TCM which has been made into a granule formulation called XFBD. This is a randomized double-blind placebo-control pilot trial to document safety and efficacy endpoint assessments and to determine the feasibility of community recruitment and enrollment of symptomatic adult outpatients with COVID-19. The 12-week pilot will have 14 days where they receive XFBD or a placebo, orally twice a day and a 10 week follow up. The study will have a total of 60 participants with approximately 30 participants in each treatment arm. The participants will be randomized 1:1 individuals.

Eligibility Criteria
Inclusion Criteria
- •Participant provides informed consent prior to initiation of any study procedures.
- •Individual 18 to 75 years of age.
- •Documentation of confirmed active SARS-CoV-2 infection, as determined by an FDA authorized molecular test conducted at any US clinic or laboratory that has a Clinical Laboratory Improvement Amendments (CLIA) certification or its equivalent from any respiratory specimen collected \<96 hours prior to study entry.
- •Mild or Moderate COVID-19 experiencing at least one SARS-CoV-2 infection symptom including:
- •Mild Covid-19: Symptoms of mild illness with COVID-19 that could include fever, cough, sore throat, malaise, headache, muscle pain, gastrointestinal symptoms, without shortness of breath or dyspnea
- •Moderate Covid-19:
- •Symptoms of moderate illness with COVID-19, which could include any symptom of mild illness or shortness of breath with exertion
- •Presence of clinical signs consistent with moderate illness with COVID-19, such as respiratory rate ≥ 20 breaths per minute, saturation of oxygen (SpO2) \> 93% on room air at sea level, heart rate ≥ 90 beats per minute from a health care encounter within 48 hours.
- •Agrees to not participate in another clinical trial for the treatment of COVID-19 or SARS-CoV-2 during the study period up until reaching hospitalization or 28 days, whichever is earliest.
- •Agrees to not utilize TCM outside of this study.
Exclusion Criteria
- •Need for hospitalization.
- •Severe or Critical COVID-19:
- •Severe COVID-19
- •Symptoms suggestive of severe systemic illness with COVID-19, which could include any symptom of moderate illness or shortness of breath at rest, or respiratory distress
- •Clinical signs indicative of severe systemic illness with COVID-19, respiratory rate ≥ 30 breaths per minute, heart rate ≥ 125 beats per minute, SpO2 ≤ 93% on room air at sea level or respiratory PaO2/FiO2 \< 300
- •Critical COVID-19 -- Evidence of critical illness, defined by at least one of the following:
- •Respiratory failure defined based on resource utilization requiring at least one of the following: Endotracheal intubation and mechanical ventilation, oxygen delivered by high flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates \> 20 L/min with fraction of delivered oxygen ≥ 0.5), noninvasive positive pressure ventilation, ECMO, or clinical diagnosis of respiratory failure (i.e., clinical need for one of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation)
- •Shock (defined by systolic blood pressure \< 90 mm Hg, or diastolic blood pressure \< 60 mm Hg or requiring vasopressors)
- •Multi-organ dysfunction/failure
- •Positive SARS-CoV-2 molecular test in the absence of Covid-19 symptoms. However if patients develop symptoms within 14 days of the positive test and fulfill all other enrollment criteria, they are eligible for participation.
