- HIV negative
- No GvHD
- No continuing use of immunosuppressive drugs
- Absence of active systemic fungal or viral infection including HTLV-1, hepatitis B or C.
- Adequate renal and liver function confirmed by: creatinine clearance \>30mls/min; bilirubin \<3.0 x upper limit of normal; AST \<3.0 x upper limit of normal; prothrombin time \<2.0 x upper limit of normal.
