This individually randomized telemedicine-based trial aims to evaluate the efficacy of a single dose of azithromycin for prevention of progression of COVID-19 in patients with a recent positive SARS-CoV-2 test who are not currently hospitalized.
Identification of a safe, effective treatment for individuals with mild or moderate COVID-19
that prevents disease progression and reduces hospitalization would reduce the burden on the
health system. High dose hydroxychloroquine is being evaluated for SARS-CoV-2 prevention and
COVID-19 disease treatment, but has a high risk of a number of potentially severe adverse
events. Recent evidence has indicated that the broad-spectrum macrolide azithromycin may have
some activity against coronaviruses. Here we propose an individually-randomized,
placebo-controlled trial to determine the efficacy of a single dose of azithromycin for
prevention of COVID-19.
Potential participants will undergo remote eligibility screening with study staff prior to
enrollment. Upon determination of eligibility and signing electronic informed consent
documents, participants will be emailed baseline study forms and will be mailed their
randomized study treatment. At the end of the study (21 days), participants will be emailed a
final study questionnaire. Note that there will no contact between study staff and
participants in this trial, minimizing risk of infection spread.
Drug: Azithromycin
Participants will be shipped a single 1.2 g dose of oral azithromycin
