Numerous federal services in the U.S. have been suspended due to the ongoing government shutdown. Among the services affected was the federal registry of clinical trials, accessible via the website ClinicalTrials.gov. New trials were not being entered into the registry and made available for enrollment. As a result, many people, including patients with advanced cancer, were unable to enroll in studies offering potentially lifesaving experimental treatments. However, after a U.S. Congressman contacted the National Institutes of Health (NIH), which administers the database, a small number of furloughed workers was called back to reopen the website. While the site is not fully operational, processing of clinical trial registrations has resumed, along with updates of the most critical information.
