|Covid-19||Drug: Famotidine Drug: Placebo||Phase 2|
The outbreak of coronavirus disease 2019 (COVID 19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was first reported in Wuhan, China, in 31 December 2019 and was declared as a global health emergency on 30 January 2020. Currently, there are no definitive vaccine, therapeutic antibody, or antiviral drug countermeasures currently authorized by the FDA for prevention or treatment of mild to moderate COVID-19 disease.
Famotidine is a histamine-2 receptor antagonist, widely available over-the-counter and at low cost, does not interact with other medications and is safely used for suppression of gastric acid production. This makes it a candidate medication for an ambulatory setting to alleviate the symptoms and shorten the symptomatic period in this population. In a case series of 10 patients with COVID-19 who self-medicated with oral famotidine, significant improvement of symptoms was associated with famotidine use after 24-48 hours. These effects were noted in patients who mostly took doses of 80mg three times daily suggesting that famotidine's action is either through its main known high affinity target, the histamine type 2 receptor or through combined inhibition of histamine receptors. Famotidine may work through reduction of H2R signaling on monocytes with a resulting reduction of cytokine release.
The working hypothesis is that famotidine will be superior to placebo in reducing disease related symptoms in non-hospitalized COVID-19 patients with mild or moderate disease. Patients will be monitored for the duration of the study, as well as be asked to record the severity of their symptoms through a daily questionnaire. Current standard of care (SOC) for patients with mild to moderate COVID-19 in the outpatient setting is to assess risk for severe disease and determine the need for an in-person visit, thromboprophylaxis and adjustment of home medication regimen. If the SOC for COVID-19 patients in the outpatient setting changes during the course of the study, a request will be submitted to modify sections of the protocol.

Active Comparator: Famotidine
Participants in this study arm will receive standard of care and prescribed famotidine at 80mg TID for a maximum of 14 days, or until hospital admission.

Placebo Comparator: Placebo
Participants in this study arm will receive standard of care and placebo for a maximum of 14 days.
Standard of care treatment plus placebo
- Cumulative incidence of symptom resolution [ Time Frame: Day 28 ]Measured by the cumulative incidence of symptom resolution using the "COVID-19 Symptom Score" derived from the answers to a questionnaire based on the NIH endorsed guidelines and the recent FDA guidelines for studying COVID-19 in an outpatient setting. A shorter version has been utilized as a scoring system in the case series of famotidine use in non-hospitalized patients with COVID-19.
- Rate of symptom resolution [ Time Frame: Day 28 ]Assessed by modelling the resolution of cumulative symptoms over time
- Cumulative incidence of symptom resolution [ Time Frame: Day 60 ]Assessed using the "COVID-19 Symptom Score"
- Relative change of symptoms [ Time Frame: Day 7 ]Assessed using the "COVID-19 Symptom Score"
- Assessment of Serious Adverse Events [ Time Frame: Day 60 ]Number of participants with treatment-related adverse events as assessed by CTCAE v4.0.
- Clinical improvement [ Time Frame: Day 28 ]Assessed using the 9-point ordinal scale recommended by the WHO for trials enrolling patients with COVID-19.
- Improvement in peripheral oxygen saturation [ Time Frame: Day 7 ]Measured by pulse oximetry in % oxygen saturation.
- Mortality [ Time Frame: Day 28 ]Assessed by counting mortality in each arm
- Comparative proportions of hospitalized patients [ Time Frame: Day 0-28 ]Measured by the proportions of patients having been hospitalized by Day 28.
- Change in CRP [ Time Frame: Day 7, 14, and 28. ]Measured by CRP [mg/L]
- Change in procalcitonin [ Time Frame: Day 7, 14, and 28. ]procalcitonin [microg/L]
- Change in ferritin [ Time Frame: Day 7, 14, and 28. ]ferritin [microg/L]
