Summary

Related donor stem cell transplantation using the alemtuzumab/ TBI platform has been shown to be a safe strategy to cure severe sickle cell disease. However, due to a lack of suitable donors, many patients cannot benefit from this strategy. Alternative donor sources are desperately needed to fill this gap. Nearly all patients will have a haploidentical family member who would be able to donate. The use of post transplantation cyclophosphamide has greatly improved the outcome of haploidentical stem cell transplantation. The investigators propose to combine this with alemtuzumab/TBI conditioning.

Conditions

Interventions

PROCEDURE

Haploidentical Transplant

All subjects will undergo pre-conditioning treatment with alemtuzumab (0.3 mg/kg Day -5, Day -4, Day -3) and total body irradiation (300cGy), followed by stem cell transplant, and post-transplant treatment with cyclophosphamide (50mg/kg/day) and sirolimus (target trough level of 10-15ng/mL).

DRUG

Alemtuzumab

On Day -7, the first test dose of alemtuzumab (0.03 mg/kg) will be administered and on Day -6, the second test dose of alemtuzumab (0.1 mg/kg) will be administered. Alemtuzumab (0.3 mg/kg) will be infused daily on Day -5, -4, and -3.

RADIATION

Total Body Irradiation

A 300cGy dose of TBI will be administered in a single fraction on Day -2.

DRUG

Cyclophosphamide

Cyclophosphamide (50 mg/kg IBW) IV, over approximately 1-2 hours, is given on Day 3 post-transplantation (ideally between 60 and 72 hours after marrow infusion) and on Day 4 (approximately 24 hours after Day 3 cyclophosphamide).

DRUG

Sirolimus

Sirolimus will be started on Day +5 (at least 24 hours after the completion of the cyclophosphamide infusion). The starting dose will be 12mg followed by 4mg PO daily. Doses will be adjusted to achieve a whole blood trough level of 4 - 12ng/mL.
