Missing clinical trial data: the knowledge gap in the safety of potential COVID-19 drugs 2020-06-03 .txt text/plain 4314 230 45 However, availability of safety information is limited by a lack of timely reporting of clinical trial results on public registries or through academic publication. We aimed to analyse the knowledge gap in safety data by quantifying the number of missing clinical trial results for drugs potentially being repurposed for COVID-19. Relevant clinical trials for any prior indication were listed by identifier (NCT number) and checked for timely result reporting (within 395 days of the primary completion date). We reviewed the number of completed or terminated trials that have not reported results for an extensive, list of medications being repurposed for COVID-19, looking at all previous indications for these drugs. . https://doi.org/10.1101/2020.05.30.20117523 doi: medRxiv preprint Discussion 40.4% of the completed clinical trials for drugs that may be repurposed for COVID-19 were not found to report results on either ClinicalTrials.gov or through academic publication (Table 2 ). ./cache/cord-331206-m938suxh.txt ./txt/cord-331206-m938suxh.txt
