Abstract Background The rapid emergence and the high disease burden of the novel coronavirus SARS-CoV-2 have created a medical need for readily available drugs that can decrease viral replication or blunt the hyperinflammatory state leading to severe COVID-19 disease. Azithromycin is a macrolide antibiotic, known for its immunomodulatory properties. It has shown antiviral effect specifically against SARS-CoV-2 in vitro and acts on cytokine signaling pathways that have been implicated in COVID-19. Methods DAWn-AZITHRO is a randomized, open-label, phase 2 proof-of-concept, multicenter clinical trial, evaluating the safety and efficacy of azithromycin for treating hospitalized patients with COVID-19. It is part of a series of trials testing promising interventions for COVID-19, running in parallel and grouped under the name DAWn-studies. Patients hospitalized on dedicated COVID wards are eligible for study inclusion when they are symptomatic (i.e., clinical or radiological signs) and have been diagnosed with COVID-19 within the last 72 h through PCR (nasopharyngeal swab or bronchoalveolar lavage) or chest CT scan showing typical features of COVID-19 and without alternate diagnosis. Patients are block-randomized (9 patients) with a 2:1 allocation to receive azithromycin plus standard of care versus standard of care alone. Standard of care is mostly supportive, but may comprise hydroxychloroquine, up to the treating physician’s discretion and depending on local policy and national health regulations. The treatment group receives azithromycin qd 500 mg during the first 5 consecutive days after inclusion. The trial will include 284 patients and recruits from 15 centers across Belgium. The primary outcome is time from admission (day 0) to life discharge or to sustained clinical improvement, defined as an improvement of two points on the WHO 7-category ordinal scale sustained for at least 3 days. Discussion The trial investigates the urgent and still unmet global need for drugs that may impact the disease course of COVID-19. It will either provide support or else justify the discouragement of the current widespread, uncontrolled use of azithromycin in patients with COVID-19. The analogous design of other parallel trials of the DAWN consortium will amplify the chance of identifying successful treatment strategies and allow comparison of treatment effects within an identical clinical context.

Viral Shedding

Abstract Background Duration of viral shedding is a determinant of infectivity and transmissibility, but few data exist about oseltamivir's ability to alter viral shedding. Methods From January 2012 through October 2017, a randomized, double-blinded multicenter clinical trial was conducted in adults aged 18–64 years at 42 sites in Thailand, the United States, and Argentina. Participants with influenza A or B and without risk factors for complications of influenza were screened for the study. Eligible participants were randomized to receive oseltamivir 75 mg or placebo twice daily for 5 days. The primary endpoint was the percentage of participants with virus detectable by polymerase chain reaction in nasopharyngeal swab at day 3. Results Of 716 adults screened for the study, 558 were randomized, and 501 were confirmed to have influenza. Forty-six participants in the pilot study were excluded, and 449 of the 455 participants in the population for the primary analysis had day 3 viral shedding results. Ninety-nine (45.0%) of 220 participants in the oseltamivir arm had virus detected at day 3 compared with 131 (57.2%) of 229 participants in the placebo arm (absolute difference of −12.2% [−21.4%, −3.0%], P =; .010). The median time to alleviation of symptoms was 79.0 hours for the oseltamivir arm and 84.0 hours for the placebo arm (P =; .34) in those with confirmed influenza infection. Conclusions Oseltamivir decreased viral shedding in this low-risk population. However, in the population enrolled in this study, it did not significantly decrease the time to resolution of clinical symptoms. Clinical Trials Registration NCT01314911.
