About this study

This study is a randomized, double-blinded, and placebo controlled phase III clinical trial in in adults aged 18~59 Years. The study was planned as a multicenter, randomized controlled, double-blind, parallel-arm drug study. The purpose of this study is to evaluate the efficacy and safety of hydroxychloroquine, favipiravir, or hydroxychloroquine + favipiravir treatments that were initiated early in patients who were caught during filiation or who were decided to be outpatient due to mild disease findings during hospital admission, after the diagnosis of COVID-19 against patients with placebo. It is planned that the study will be conducted with two separate arms. Study arms are planned as 2:2:2:1 for 320:320:320:160 patients as follows. The dose of Favipiravir has been determined as the standard dose. Hydroxychloroquine will also be given without a loading dose.
