Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a pragmatic, randomized, open-label, incomplete factorial with nested randomization clinical trial evaluating the efficacy and safety of two potential treatments for hospitalized patients with confirmed SARS-CoV-2 infection. Participants who are hospitalized and have a positive nucleic acid amplification test for SARS-CoV-2 will undergo an initial randomization in a 1:1 ratio to one of the following regimens: Arm 1: Standard of care alone Arm 2: Standard of care plus hydroxychloroquine Participants who meet eligibility criteria to receive azithromycin will undergo a second randomization in a 1:1 ratio to receive additional concurrent therapy. This will effectively result in four treatment groups: 1. Standard of care alone 2. Standard of care plus hydroxychloroquine 3. Standard of care plus azithromycin 4. Standard of care plus hydroxychloroquine plus azithromycin
