简要总结
This phase I/II trial is studying the side effects and best way to give nilotinib when given alone or sequentially after imatinib mesylate after donor stem cell transplant in treating patients with acute lymphoblastic leukemia or chronic myelogenous leukemia. Nilotinib and imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
详细描述
PRIMARY OBJECTIVES:
I. To determine the safety of the administration of nilotinib between Day 81 and Day 365 after hematopoietic cell transplantation (HCT) in patients with Philadelphia chromosome positive (Ph+) leukemia.
SECONDARY OBJECTIVES:
I. To quantify the breakpoint cluster region (BCR)/Abelson murine leukemia (ABL) transcript load after HCT during tyrosine kinase inhibitor therapy in patients with Ph+ leukemia treated sequentially with imatinib (imatinib mesylate) and nilotinib from the time of engraftment.
II. To evaluate survival at 1 year in patients with Ph+ leukemia who received sequential imatinib and nilotinib from the time of engraftment.

- •Serum aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 x ULN, conjugated bilirubin < 3 x ULN
- •Serum potassium phosphorus, magnesium, and calcium >= lower limit normal (LLN) or correctable with supplements prior to first dose of study drug; calcium levels may be corrected for hypoalbuminemia
- •Serum amylase and lipase < 1.5 x ULN
- •Female patients of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing; postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential; male and female patients of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug
- •Careful rationalization with a view to discontinuing or considering alternatives to any concomitant medications that have potential to prolong the QT interval
排除标准
- •Autologous transplant
- •Non-myeloablative transplant
- •Patient age > 17 years with CML in first chronic phase

- •Known T315I mutation
- •Hypersensitivity to Gleevec or Tasigna
- •Patients who are Tasigna-resistant or intolerant
- •Central nervous system (CNS) involvement with leukemia at baseline (pre-imatinib therapy); CML chronic phase (CP), accelerated phase (AP) patients exempt from CNS involvement screening
- •Female patients who are pregnant, breast-feeding, or of childbearing potential without a negative serum pregnancy test at screening; male or female patients of childbearing potential unwilling to use effective contraceptive precautions throughout the trial; post-menopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential

- •Complete left bundle branch block or bifascicular block (right bundle branch block plus left anterior hemiblock) or use of ventricular-paced pacemaker
- •Congenital long QT syndrome or a family history of long QT syndrome
- •History of or presence of significant ventricular or atrial tachyarrhythmias
- •Clinically significant resting bradycardia (< 50 beats per minute)
- •Corrected QT interval (QTc) > 450 milliseconds on screening electrocardiogram (ECG); if QTc > 450 and electrolytes are not within normal ranges, electrolytes should be corrected and then the patient rescreened for QTc
研究组 & 干预措施
Treatment (prophylactic inhibition of BCR-ABL tyrosine kinase)
Beginning after engraftment and blood count recovery (21 to 28 days after allogeneic stem cell transplant), patients with imatinib-sensitive leukemia receive imatinib mesylate PO QD until day 80 and then nilotinib PO BID on days 81-445. Patients with imatinib-resistant leukemia receive nilotinib PO BID beginning after engraftment and blood count recovery until day 445.
Treatment continues in the absence of disease progression or unacceptable toxicity.
干预措施: nilotinib (Drug)

结局指标
主要结局
Number of Participants With Treatment Safety Failure
时间窗: Up to 365 days post-transplant
Safety and tolerability of nilotinib therapy in patients with imatinib-sensitive leukemia graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events version 4.0. Treatment safety failure is defined for a patient with imatinib sensitive Ph+ leukemia as the inability to be able to deliver at least 400 milligrams per day of nilotinib in adults, and 230 milligrams/m2 per day in children, for at least 85% of the time interval between 81 and 365 days after transplant. The overall study will be considered successful if nilotinib is deliverable to more than 75% of the study participants at this minimum specified dose intensity.
