Bone drug tested to shield young transplant survivors from fractures
NCT ID NCT07375290
First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This early study tests whether giving a bone-strengthening drug called zoledronate soon after a stem cell transplant can safely prevent bone loss and fractures in children. Researchers will enroll 20 children aged 5 to 18 who are at high risk for bone problems. The goal is to see if the drug is safe and practical to use in this setting.
