Study of Oral Administration of Ribavirin and Nitazoxamide Versus Placebo in COVID-19

This is a single center, randomized, double-blind, 2-arm, parallel-group study of DuACT in participants with clinical symptoms of COVID-19 that have begun within the past 72 hours prior to testing. A confirmatory diagnosis of COVID-19 via nasopharyngeal swab, with a positive PCR result within 48 hours of testing. Consented participants who complete screening and meet study eligibility criteria will be randomized in a 1:1 ratio to receive DuACT or Placebo for 5 days. Study drugs will be administered BID for 5 days with a loading dose on Day 1. Following randomization, participants will complete a symptom questionnaire, record temperature and record oxygen saturation daily for 10 days and at day 28. A thermometer and pulse oximeter will be provided to each patient at the baseline visit (Day 1). On study days 3, 6 and 10 participants will have a clinic or home visit by a home healthcare provider. At these visits, a mid-turbinate nasal swab will be obtained, confirmation of the patient's clinical symptoms questionnaire will be completed and any adverse events will be assessed.
