Brief summary
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
Interventions
Standard of care
Hydroxychloroquine will be administered orally or via feeding tube at a dosage of 800 mg on day 1, followed by 600 mg daily on days 2-5
Azithromycin will be administered orally or via feeding tube at a dosage of 500 mg on day 1, followed by 250 mg daily on days 2-5

Intervention model description
Patients will be initially randomized to one of two arms in a 1:1 ratio: 1) Standard of care treatment or 2) Standard of care treatment plus 5 days of hydroxychloroquine. Participants who meet eligibility criteria to receive azithromycin will undergo a second randomization in a 1:1 ratio to receive additional concurrent therapy.
