In this report, we provide a description of the effect of the COVID-19 pandemic on ongoing clinical trials. Historical metadata of all trials reported on Clin-icalTrials.gov from January 1, 2017, to May 31, 2020, were queried by using Python (Python Software Foundation, Beaverton, Oregon). The months from January 1 to May 31, 2020, were defined as the COVID-19 pandemic period. Non-COVID-19-related trials were identified by excluding "COVID," "coronavirus," and "SARS-CoV-2" in trial titles. Stopping a trial was defined as a switch in trial status from "recruiting" to "active and not recruiting," "completed," "suspended," "terminated," or "with- We found that during the initial months of the COVID-19 pandemic, the rate of clinical trials that were stopped increased significantly compared with the pre-pandemic era.
