New treatment option for Severe Aplastic Anemia
Official title Clinical Trial of Upfront Haploidentical or Unrelated Donor BMT to Restore Normal Hematopoiesis in Aplastic Anemia
ClinicalTrials.gov ID: NCT06517641
What this study is testing
What is Haploidentical donor bone marrow transplant?
Haploidentical donor bone marrow transplant is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for severe aplastic anemia.
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
- BMT CTN 2207 will investigate the use of marrow transplantation for treatment of severe aplastic anemia that has not previously been treated.
- 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.
