OUTLINE: This is a phase I, dose-escalation study of bosutinib followed by a phase II study.
Patients receive bosutinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive inotuzumab ozogamicin intravenously (IV) over 1 hour on days 1, 8, and 15. Patients with confirmed complete response (CR), incomplete blood count recovery (CRi), complete cytogenetic response (CCyR) and/or absence of minimal residual disease (MRD) may receive inotuzumab ozogamicin IV on day 1 of subsequent cycles. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 12 weeks for up to 1 year.

Experimental: Treatment (bosutinib, inotuzumab ozogamicin)
Patients receive bosutinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive inotuzumab ozogamicin IV over 1 hour on days 1, 8, and 15. Patients with confirmed CR, CRi, CCyR and/or absence of MRD may receive inotuzumab ozogamicin IV on day 1 of subsequent cycles.

- Maximum tolerated dose of bosutinib defined as the highest dose level in which < 2 patients of 6 develop first course dose limiting toxicity (Phase I) [ Time Frame: At day 28 ]Will be observed.
- Major hematologic response for relapsed Philadelphia positive acute lymphoblastic leukemia (MaHR) (Phase II) [ Time Frame: Up to 16 weeks (cycle 4 of treatment) ]The response will be evaluated along with its 95% confidence interval.
- Complete response/complete response with incomplete bone marrow recovery for newly diagnosed Philadelphia positive acute lymphoblastic leukemia or chronic myeloid leukemia or chronic myeloid leukemia- lymphoid blast phase with age >= 60 (Phase II) [ Time Frame: Up to 1 year after completion of study treatment ]Will be observed.
- Overall major hematologic response (Phase I) [ Time Frame: Up to 1 year after completion of study treatment ]Will be observed.
- Duration of response (Phase I) [ Time Frame: Up to 1 year after completion of study treatment ]Estimated using the method of Kaplan-Meier. Cox regression models will be used to determine the relationship with the time-to-events and the potential prognostic factors.
- Overall survival (OS) (Phase I) [ Time Frame: Up to 1 year after completion of study treatment ]Estimated using the method of Kaplan-Meier. Cox regression models will be used to determine the relationship with the time-to-events (e.g., OS) and the potential prognostic factors.
- Incidence and severity of adverse events graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (Phase II) [ Time Frame: Up to 1 year after completion of study treatment ]Safety data will be summarized by category, severity and frequency.
- Duration of response (Phase II) [ Time Frame: Up to 1 year after completion of study treatment ]Estimated using the method of Kaplan-Meier. Cox regression models will be used to determine the relationship with the time-to-events and the potential prognostic factors.
- Overall survival (Phase II) [ Time Frame: Up to 1 year after completion of study treatment ]Estimated using the method of Kaplan-Meier. Cox regression models will be used to determine the relationship with the time-to-events (e.g., OS) and the potential prognostic factors.
