Results Overview

Evaluate the number of serious adverse effects and discontinuation secondary to toxicity through 28 days of follow-up as compared to the control arm as assessed by: Cumulative number of serious adverse events (SAEs), Cumulative number of Grade 3 and 4 adverse events (AEs), Discontinuation or temporary suspension of the investigational medication (for any reason).

Measure	Control Placebo (Methylcellulose) capsule: Placebo capsules will be prepared with opaque gelatin capsules, filled using methylcellulose and over-encapsulated to appear identical to interventional drug. Placebo capsules will be given orally in the same regimen as intervention (three times daily for 14 days). Capsules will be prepared by the research pharmacist and will be mailed to study subjects directly by courier. Placebo capsules will be stored at room temperature.	Melatonin Melatonin: Melatonin will be administered orally as a 10 mg dose three times a day for 14 days. Size 4 clear vegetable cellulose capsules containing 10 mg melatonin, microcrystalline cellulose, and rice concentrate prepared by Life Extension® will be over-encapsulated in opaque gelatin capsules. Over-encapsulation of melatonin treatments will be done by the research pharmacist and will be mailed to study subjects directly by courier. Melatonin capsules will be stored at room temperature.

COVID-19 Related Symptoms	3 participants	5 participants

SECONDARY outcome

Timeframe: 28 days

Population: 1 participant in each group was hospitalized and 1 was lost to follow up.

We designed a COVID-19 symptom scale. Participants rated 11 COVID related symptoms on a scale of 0-5. A maximum score of 55 would indicate the worst symptoms, while a score of 0 would indicate no symptoms. Change from baseline (day 1) in the total symptoms score was assessed on days 3, 7, 14, and 28.
