New study aims to reduce allergic reactions in stem cell therapy for multiple myeloma
NCT ID NCT07101445
First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 4 times
Summary
This study tests whether methylprednisolone works better than dexamethasone at preventing allergic reactions to motixafortide, a drug used to help collect stem cells for transplant in multiple myeloma patients. About 94 adults with multiple myeloma will be randomly assigned to receive one of the two premedication drugs before motixafortide. The goal is to find which regimen causes fewer and less severe reactions, improving the safety of stem cell collection.

Inclusion Criteria: * Patients must be aged 18 years or older. * Patient must understand and voluntarily signed an informed consent form. * Patient must be willing and able to adhere to the study schedule and other protocol requirements. * Histologically confirmed multiple myeloma prior to enrollment and randomization. * Eligible for hematopoietic stem cell mobilization and autologous hematopoietic stem cell transplantation as per institutional guidelines. * Females of reproductive potential must use effective contraception during treatment with motixafortide and for 8 days after the final dose. Exclusion Criteria: * Previous history of autologous or allogeneic hematopoietic cell transplantation. * History of hemoglobin SS disease or hemoglobin S trait precluding the patient's ability to use G-CSF. * History of steroid-induced psychosis or encephalopathy requiring medical intervention. * History of type I or II diabetes mellitus that is poorly controlled or with high glucose variability precluding safe administration of dexamethasone 12mg IV as premedication in the opinion of the investigator. * History of serious systemic reaction to motixafortide.
