Brief Summary:
This study is a pilot randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of melatonin in adult outpatients suspected to be afflicted with COVID-19.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Melatonin Other: Placebo (Methylcellulose) capsule Phase 2

Detailed Description:
This study is a pilot randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of melatonin in outpatient adult patients suspected to be afflicted with COVID-19. Participants will be enrolled as outpatients within 72 hrs of onset of COVID-19 symptoms. The study will evaluate the safety of the intervention through 28 days of follow-up as compared to the control arm as assessed by cumulative incidence of serious adverse events (SAEs), cumulative incidence of Grade 3 and 4 adverse events (AEs), and/or discontinuation or temporary suspension of the investigational medication (for any reason). Additionally, the study will aim to evaluate the clinical efficacy of melatonin as compared to placebo as assessed by hospitalization, COVID-19 related symptoms and mortality. The ultimate goal is to determine in an adequately powered study if the anti-inflammatory and antioxidant actions of Melatonin can reduce the severity and prevent progression of COVID-19 when started in mild disease.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Placebo Comparator: Control
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.
 Other: 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.
Other Name: Methylcellulose
Experimental: 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.
 Drug: 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.
Other Name: 5-methoxy-N-acetyl tryptamine

Primary Outcome Measures :
  1. Cumulative Incidence of Treatment-Emergent Adverse Events [ Time Frame: 28 days ]
    Evaluate the incidence 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 incidence of serious adverse events (SAEs), Cumulative incidence of Grade 3 and 4 adverse events (AEs), Discontinuation or temporary suspension of the investigational medication (for any reason).


Secondary Outcome Measures :

    COVID-19 related symptoms (Fever, chills, cough, nasal symptoms, body aches/muscle aches, headache, loss of smell, loss of taste, nausea, vomiting, diarrhea, fatigue, dizziness) that are self-reported and on interview.

  3. Rate of resolution of COVID-19 related symptoms [ Time Frame: 28 days ]
    Change from baseline (day 1) as assessed to days 3, 7, 14, and 28

  4. Mortality [ Time Frame: 28 days ]
    28-day mortality
