Study Description

Brief Summary:

This study is a multicenter randomized trial to evaluate the efficacy of administering a dietary supplement containing resistant starch to non-hospitalized COVID-19 positive subjects, The intervention will begin as soon as possible after subjects test positive for COVID-19 and continue for 14 days. Investigators hypothesize that short-term administration of a dietary supplement containing resistant starch has the potential to reduce rates of hospitalization and improve time to clinical recovery and symptoms in non-hospitalized COVID-19 positive patients.

Condition or disease	Intervention/treatment	Phase
COVID-19	Drug: Dietary Supplement containing resistant starch; Dietary Supplement: Placebo Starch	Phase 2; Phase 3

Detailed Description:

The COVID-19 pandemic has caused a substantial strain on the healthcare system, with at least 14% of infected patients requiring hospitalization. Identifying ways to ameliorate the progression and severity of the COVID-19 infection and preventing hospitalization is critical. Patients suffering from COVID-19 have been shown to have a significant inflammatory response resembling that of cytokine release syndrome, and it is this inflammatory phase that is thought to drive fatality.

To this end, a multi-center randomized clinical trial to determine the efficacy of resistant starch in reducing the need for hospitalization for COVID-19 positive patients will be studied. This study will enroll 1500 non-hospitalized COVID-19 positive individuals who are being monitored in the outpatient setting. Patients will be randomized to either a dietary supplement containing resistant starch or a placebo for 14 days. Our primary outcome is the rate of hospitalization for COVID-19 related complications. Secondary outcomes will look at time to recovery and symptom severity scores.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Intervention; Subjects will receive a dietary supplement containing resistant starch and be instructed to take 2 tablespoons (~20 grams) twice daily for 14 days. Initially subjects will take 2 tablespoons once daily for the first three days prior to increasing to 2 tablespoons twice daily.	Drug: Dietary Supplement containing resistant starch; Two tablespoons (~ 20 grams) to be taken twice daily for 14 days (start with 2 tablespoons once daily for three days, followed by twice daily on days 4 through 14); Other Name: Resistant Starch
Placebo Comparator: Control; Subjects will receive a placebo starch, consisting of non resistant starch and be instructed to take 2 tablespoons (~ 20 grams) twice daily for 14 days. Initially subjects will take 2 tablespoons once daily for the first three days.	Dietary Supplement: Placebo Starch; Two tablespoons (~ 20 grams) to be taken twice daily for 14 days (start with 2 tablespoons once daily for three days, followed by twice daily on days 4 through 14); Other Name: Non Resistant Starch

Outcome Measures

Primary Outcome Measures :

1. Rates of hospitalization for a COVID-19 related complication (Phase 3) [ Time Frame: One month from the start of treatment ]
   Hospitalization for a COVID-19 related admission during the first month of follow up. Death prior to hospitalization thought to be secondary to COVID-19 will also be defined as an event.

Secondary Outcome Measures :

1. Time to clinical recovery (TTCR) (Phase 2) [ Time Frame: One month from the start of treatment ]
   Time to clinical recovery will be defined by a return to normal body temperature (97-99 degrees F) as reported by the patient, and resolution of major presenting symptoms (myalgia, cough, shortness of breath, and GI symptoms) maintained for 72 hours. Patients will be called every 2 days for the first 14 days of the study, and then once weekly for the following 14 days to assess symptoms via a pre-specified questionnaire. Patients will continue to be followed for an additional 3 months by electronic medical record review.
2. Symptom Severity Score (Phase 2) [ Time Frame: One month from the start of treatment ]
   This score will be evaluated using a subjective self-reporting questionnaire around 8 symptoms, which include: shortness of breath at rest or exertion, fatigue, myalgia/muscle aces, fever, cough, headache, GI symptoms, inability to taste or smell. Subjects will rate each of their symptoms on an ordinal scale as follows: absent (0), mild (1), moderate (2), or severe (3). These symptom ratings will be added to define the symptom severity score with a possible score range of 0-24 points. Subjects will be called every 2 days for the first 14 days of the study, and then once weekly for the following 14 days to assess symptoms via this pre-specified questionnaire. Patients will continue to be followed for an additional 3 months via EHR review.
