Severe aplastic anemia is a serious condition where the bone marrow doesn't make enough blood cells. This study tests a special type of bone marrow transplant called haploidentical transplant, using mismatched family donors. Patients first take medicines like Fludarabine, Cyclophosphamide, and get a treatment called TBI (Total Body Irradiation) to prepare their bodies. After the transplant, Cyclophosphamide is given on Days 3 & 4 to help the body accept the new bone marrow. Medicines called Tacrolimus and MMF are then used to prevent rejection of the new marrow. MMF stops on Day 35, but Tacrolimus continues until Day 180. The study aims to see if this method has less than 30% failure.
- Involves multiple visits over 180 days for treatment and monitoring.
- Patients must have a family donor with a partial match.
- Risks include potential graft failure and side effects from the medicines.
