Could shorter antibiotic courses be safer for blood cancer patients?
NCT ID NCT07372131
First seen Jun 27, 2026 · Last updated Jul 16, 2026 · Updated 2 times
Summary
This study looks at whether blood cancer patients with a serious infection can safely stop antibiotics sooner if they are stable for 72 hours, instead of the usual 10-day course. About 172 adults will be randomly assigned to either a personalized short course or standard long course. The goal is to see if shorter treatment reduces antibiotic use and side effects without increasing risks like infection return or death.
