実験的:Bosutinib and Bone Marrow Transplant
Subjects will receive 400mg of bosutinib from day at least -45 to day -15 to assess the sensitivity of patient Chronic Myeloid Leukemia (CML) to this TKI.
Patients will be transplanted with the aim to transplant > 3 x 106 CD34+ cells/kg Body Weight (BW) recipient from bone marrow or > 3 x 108 nucleated cells/kg BW recipient from bone marrow.
Then, subjects will receive 400mg of bosutinib once daily from day +30 after transplant.
|
Subjects will receive 400mg of bosutinib once daily from day +30 after transplant, by mouth with food, preferably in the morning.
Bosutinib will also be administered from day at least -45 to day -15 to assess the sensitivity of patient CML to this TKI.
他の名前:
Samples of the unrelated stem cell graft shall be characterised with respect to the number of CD34 positive cells per kg body weight of the recipient. The number of transplanted CD34 positive cells per kg body weight (BW) of the recipient shall be recorded in the Case Report Form (CRF). If the transplant was cryopreserved the number of viable CD34 positive cells has to be determined after thawing and documented. The goal is to transplant > 3 x 106 CD34+ cells/kg BW recipient from bone marrow or > 3 x 108 nucleated cells/kg BW recipient from bone marrow |

Efficacy as assessed by the percentage of patients with Complete Cytogenetic Response (CCyR)
時間枠:12 months

The percentage of patients with Complete Cytogenetic Response (CCyR) will be calculated as the complement to the percentage of failures on the total number of patients treated, where failure includes the following events: no engraftment, death within 12 months, no CCyR at 12 months.
