Dasatinib in Treating Patients With Chronic Myelogenous Leukemia or Acute Lymphoblastic Leukemia
Study Details
Study Description
Brief Summary
RATIONALE: Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
PURPOSE: This phase I trial is studying the side effects of dasatinib in treating patients with chronic myelogenous leukemia or acute lymphoblastic leukemia.

Phase 1 |
Detailed Description
OBJECTIVES:
Primary
- Determine the long-term safety and tolerability of dasatinib in patients with Philadelphia chromosome-positive chronic myelogenous leukemia or acute lymphoblastic leukemia resistant or intolerant to imatinib mesylate.
Secondary
-
Describe any hematologic or cytogenetic response in patients treated with this drug.
-
Determine the duration of hematologic and cytogenetic response in patients using this drug during trial UCLA-0303035.
-
Determine the progression-free survival and overall survival of patients treated with this drug.
OUTLINE: This is an open-label, roll-over study of protocol UCLA-0303035.
Patients receive oral dasatinib once or twice daily for 5, 6, or 7 days. Treatment repeats every 7 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for 5 years.
PROJECTED ACCRUAL: A total of 54 patients will be accrued for this study.
