Brief summary

The PATCH trial (Prevention And Treatment of COVID-19 with Hydroxychloroquine) is funded investigator-initiated trial that includes 3 cohorts. Cohort 1: a double-blind placebo controlled trial of high dose HCQ as a treatment for home bound COVID-19 positive patients; Cohort 2: a randomized study testing different doses of HCQ in hospitalized patients; Cohort 3: a double blind placebo controlled trial of low dose HCQ as a preventative medicine in health care workers.
