This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
IntroductionEfficient therapeutic strategies are needed to counter the COVID-19 pandemic, caused by the SARSCoV-2 virus. In a context where specific vaccines are not yet available, the containment of the pandemic would be facilitated with efficient prophylaxis. MethodsWe screened several clinical trials repositories and platforms in search of the prophylactic strategies that are investigated against COVID-19 in late April 2020. ResultsUp to April 27, 2020, we found 68 clinical trials targeting medical workers (n = 43, 63%), patients relatives (n = 16, 24%) or individuals at risk of severe COVID-19 (n = 5, 7%). (Hydroxy)chloroquine was the most frequently evaluated treatment (n = 46, 68%), before BCG vaccine (n = 5, 7%). Sixty-one (90%) clinical trials were randomized with a median of planned inclusions of 600 (IQR 255-1515). ConclusionThe investigated prophylaxis strategies cover both pre- and post-exposure prophylaxis and study numerous immune enhancers and antivirals, although most research efforts are focused on (hydroxy)chloroquine.
