Remotely-conducted Trial of Famotidine vs Placebo for Patients at Home With Coronavirus (COVID) of 2019 (COVID-19)

Kit for reading vital signs (thermometer, wrist blood pressure device, finger oximeter) and with study drug is overnighted to qualified subjects with early symptoms of COVID-19. Subjects take a 20-milligram (mg) tab of famotidine or matching placebo twice a day, increase to 1 tablet every 8 hours if not better the 2nd day, and continue same for 30 days. Vital signs, symptoms, compliance etc are rechecked daily for the 30 days and once again 60 days after starting study drug. Consent, baseline, and follow-up are handled via internet plus calls/texts/virtual visits from study nurse or doctor as needed for clarifications and compliance.

If an Over-The-Counter (OTC) medication could prevent worsening and hospitalization for COVID-19, it could stop the devastation wrought by the pandemic, and do so at a low cost. One OTC medication has a pre-clinical and clinical rationale to help: famotidine. For this study, 150 subjects are randomly assigned 50:50 to blinded treatment with 1 (20-milligram) tablet famotidine or matching placebo twice a day and can increase to 1 tablet three times a day. This internet-driven study requires subjects to maintain contact with and follow advice of their local MD, so it does not increase their risks from the disease. Baseline eligibility checklist follows informed consent. Subjects must have at least 5 of the standard symptoms of COVID19, be willing to keep taking study medicine and reporting results daily for 30 days, must start within the first 6 days of symptoms, and must have a study partner to complete their follow-up in case they become unable. The rate of subjects worsening or getting hospitalized is the main outcome measure.
