Study Details

Brief summary:

Severe aplastic anemia is a rare and serious form of bone marrow failure related to an immune-mediated mechanism that results in severe pancytopenia and high risk for infections and bleeding. Patients with matched sibling donors for transplantation have a 80-90% chance of survival; however, a response rate with just immunosuppression for those patients lacking suitable HLA-matched related siblings is only 60%. With immunosuppression, only 1/3 of patients are cured, 1/3 are dependent on long term immunosuppression, and the other 1/3 relapse or develop a clonal disorder. Recent studies have shown that using a haploidentical donor for transplantation has good response rates and significantly lower rates of acute and chronic GVHD.

Interventions and Outcome Measures

Arms

experimental: Flu/Cy/TBI

Fludarabine, Cyclophosphamide, TBI followed by bone marrow transplantation. Post-transplant Cyclophosphamide will be on Days 3 \& 4.

Interventions

Fludarabine

30 mg/m2 IV QD x 5 days (Days -6 to -2)

Cyclophosphamide

14.5 mg/kg/day IV x 2 doses (Days -6 \& -5)

Total Body Irradiation

300 cGy x1 dose (Day -1)

Rabbit ATG

1.5 mg/kg/day x 3 days (Days -3 to -1)

Cyclophosphamide

Post-transplant: 50 mg/kg IV QD (Day +3 to +4)

Primary outcome measure

  • Demonstrate sustained engraftment after T-cell replete HLA-mismatched haploidentical bone marrow transplantation by collecting chimerism tests monthly following transplant [ Time Frame: 2 years ]
