New treatment option for Sickle Cell Disease
Official title Sickle Cell Disease Transplant Using a Nonmyeloablative Approach for Patients With Anti-donor Red Cell Antibody
ClinicalTrials.gov ID: NCT06358638
What this study is testing
What is Daratumumab?
Daratumumab is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for sickle cell disease.
Also referred to as Darzalex.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This multicenter prospective study seeks to determine if daratumumab given, prior to HLA-identical sibling donor transplantation using alemtuzumab, low dose total-body irradiation, and sirolimus, can prevent pure red blood cell aplasia with an acceptable safety profile in patients with anti-donor red blood cell antibodies, achieving an event-free survival similar to transplanted patients without such antibodies.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
