Could skipping preventive antibiotics be safer for stem cell transplants?
NCT ID NCT07308457
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether closely watching for infections without giving preventive antibiotics works as well as giving a daily antibiotic (ceftriaxone) in adults getting stem cell transplants. The goal is to see if skipping preventive antibiotics is safe, especially in hospitals where bacteria are often resistant to common drugs. One hundred adults with blood cancers or other conditions will take part.
