Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 269

Inclusion Criteria

•Patients must have the following laboratory values:
Potassium = LLN (lower limit of normal) or correctable with supplements
Total calcium (corrected for serum albumin) = LLN or correctable with supplements
Magnesium = LLN or correctable with supplements
Phosphorus = LLN or correctable with supplements
ALT and AST = 2.5 x ULN or = 5.0 x ULN if considered due to tumor
Alkaline phosphatase = 2.5 x ULN
Serum bilirubin = 1.5 x ULN
Serum creatinine = 1.5 x ULN or 24-hour creatinine clearance ? 50 ml/min

Phase I
•Patients with a cytopathologically confirmed diagnosis of Ph+ ALL who are either relapsed after or refractory to standard therapy, or patients with CML in BC, or CML patients in CP or AP who are resistant to Gleevec®. Patients with Ph+ ALL who have minimal residual disease following stem cell transplantation may only be enrolled during the dose escalation portion of the study.

Phase II- CML
1. Imatinib resistant or intolerant Ph+ CML in blast crisis defined as at least 30% blasts in peripheral blood or bone marrow or extramedullary disease other than liver or spleen
2. Imatinib resistant or intolerant Ph+ CML patients in accelerated phase defined as never in blast crisis before starting treatment, with one or more of the following criteria present within 4 weeks prior to beginning treatment:
•=15% but <30% blasts in blood or bone marrow
•=30% blasts plus promyelocytes in peripheral blood or bone marrow (providing that <30% blasts present in bone marrow)
•peripheral basophils =20%
•thrombocytopenia <100 X 109 /L unrelated to therapy
3. Imatinib resistant or intolerant Ph+ CML in chronic phase defined as never in blast crisis or accelerated phase before starting treatment and the presence of the following criteria:
•< 15% blasts in peripheral blood and bone marrow
•< 30% blasts plus promyelocytes in peripheral blood and bone marrow
•< 20% basophils in the peripheral blood
•= 100 x 109 /L (= 100,000 /mm3) platelets
•No evidence of extramedullary leukemic involvement, with the exception of liver or spleen

Phase II: Relapsed or refractory Ph+ ALL
•Patients with Ph+ ALL who have minimal residual disease (MRD) are eligible only if there is indication of evolving relapse defined as a = 2 log increase of Bcr-Abl transcript level (as reported by local laboratories), as compared to the minimum level achieved with prior therapy in peripheral blood
•Patients with Ph+ALL whose disease exhibits features of biphenotypic acute leukemia are eligible

Phase II: Hypereosinophilic syndrome/chronic eosinophilic leukemia
•eosinophilia greater than 1500/mm3 for at least 6 months
•exclusion of other causes of eosinophilia including clonal or abnormal T-cell populations, exclusion of reactive eosinophilia, and malignancies or T-cell disorders associated with eosinophilia
•signs and symptoms of organ involvement

Phase II: Systemic mastocytosis who have a clinical indication for treatment and meet at least one major and one minor or three minor criteria (
Major criterion: Multifocal dense infiltrates of mast cells (>15 mast cells in aggregates) in bone marrow biopsies and/or in sections of other extracutaneous organ(s).
Minor Criteria: see protocol section 3.3.2.1.2

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

•Cytopathologically confirmed CNS infiltration
NB: in absence of suspicion of CNS involvement, lumbar puncture is not required
•Impaired cardiac function, including any one of the following
•LVEF < 45% as determined by MUGA scan or echocardiogram
•Complete left bundle branch block
•Use of a cardiac pacemaker
•ST depression of > 1mm in 2 or more leads and/or T wave inversions in 2 or more contiguous leads
•Congenital long QT syndrome
•History of or presence of significant ventricular or atrial tachyarrhythmias
•Clinically significant resting bradycardia (< 50 beats per minute)
•QTc > 480 msec on screening ECG (using the QTcF formula)
•Right bundle branch block plus left anterior hemiblock, bifascicular block
•Myocardial infarction within 3 months prior to starting AMN107
•Angina pectoris
•Other clinically significant heart disease (e.g., congestive heart failure, uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen)
•Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of AMN107 (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
•Use of therapeutic warfarin.
•Acute or chronic liver or renal disease considered unrelated to tumor
•Other concurrent severe and/or uncontrolled medical conditions (e.g., uncontrolled diabetes, active or uncontrolled infection) that could cause unacceptable safety risks or compromise compliance with the protocol
•Treatment with any hematopoietic colony-stimulating growth factors (e.g., G-CSF, GM-CSF) = 1 week prior to starting study drug. Erythropoietin is allowed.
•Patients who are currently receiving treatment with any of the medications listed in Post-text supplement 4 and the treatment cannot be either discontinued or switched to a different medication prior to starting study drug. The medications listed in Post-text supplement 4 have the potential to prolong the QT interval.
•Patients who have received chemotherapy = 1 week (6 weeks for nitrosurea or mitomycin-C) or who are within 5 half-lives of their last dose chemotherapy dose prior to starting study drug or who have not recovered from side effects of such therapy.
•Patients who have received Gleevec® = 1 week or who have not recovered from side effects of such therapy.
•Patients who have received immunotherapy =1 week prior to starting study drug or who have not recovered from side effects of such therapy
•Patients who have received any investigational drug = 4 weeks or investigational cytotoxic agent within 1 week (or who are within 5 half-lives of a previous investigational cytotoxic agent) prior to starting study drug or who have not recovered from side effects of such therapy
