Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Bosutinib and Bone Marrow Transplant
Arm Description
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.
Outcomes
Primary Outcome Measures
Efficacy as assessed by the percentage of patients with Complete Cytogenetic Response (CCyR)
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.
Secondary Outcome Measures
Overall Survival
Percentage of patients with engraftment
percentage of patients with complete chimerism (95%)
Evaluation of Major Cytogenetic Response (MCyR)
Major Cytogenetic Response (MCyR) is < 36% Ph+ metaphases
Evaluation of molecular responses
Molecular response is defined
Complete: if there is undetectable BCR-ABL transcript
Major: if ratio BCR/ABL <= 0.1% on International Scale
Relapse incidence (RI)
Incidence of non-relapse mortality (NRM)
Incidence and severity of acute and chronic graft vs. host disease (GvHD)
Quality of Life (QoL)
Evaluation of QoL with EQ-5D-5L (Italian - Version 2) and FACT-Leu (Italian -Version 4)
Overall Survival (OS)
2 years after transplantation of the last patient included (this is intended to allow evaluations of all expected major molecular responses)
Progression Free Survival (PFS)
2 years after transplantation of the last patient included (this is intended to allow evaluations of all expected major molecular responses)

5. Study Description
Brief Summary
Patients newly diagnosed with chronic phase chronic myeloid leukemia undergo treatment with TK inhibitors (TKI). A possible cause of TK failure is represented by the insufficient recovery of normal Ph- hematopoiesis during TKI treatment, with consequent severe cytopenias that limit TKI adequate administration. Although rare, this event happens in a proportion of 4-5% of CML patients. Our hypothesis is to circumvent this peculiar condition by providing a normal hematopoiesis from a HLA-matched donor (Human Leukocyte Antigen). The transplant procedure is therefore intended in providing a sustained hematopoiesis that will allow an early treatment with an adequate dosing of TKI. The transplant procedure planned in our study is built on all available evidences to provide the lowest incidence of acute and chronic GvHD (Graft-versus-host disease). Therefore, a bone marrow will be the preferential source and a GvHD prophylaxis based on Anti-thrombocyte globulin (ATG) and Cyclosporine/Methotrexate will be used according to standard current experience in the field of family and unrelated donors. The pre-transplant TKI will be continued until aplasia will develop, in order to decrease the tumor load as much as possible.The use of TKIs shortly after transplant carries the risk of inhibiting the newly transplanted hematopoietic cells, as Kit, an important kinase in normal bone marrow cells, is frequently blocked by Abl inhibitors. The use of bosutinib as post-transplant therapy is justified by the lack of Kit inhibition that distinguishes bosutinib from all other TKIs, and which could allow a minimal inhibitory activity against the transplanted normal bone marrow.

Intervention Description
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.
Intervention Type
Procedure
Intervention Name(s)
Bone Marrow Transplant

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
