To determine the efficacy of ponatinib in patients with chronic myeloid leukemia in chronic, accelerated or blast phase or with Ph+ Acute Lymphoblastic Leukemia who are either: - resistant or intolerant to either dasatinib or nilotinib, or - have the T315I mutation.
|
|
E.2.2 | Secondary objectives of the trial |
1. To further characterize the anti-leukemia activity of ponatinib in these patients as evidenced by clinical responses, molecular responses, and clinical outcomes; 2. To characterize the molecular genetic status of patients; and 3. To examine the safety of ponatinib in these patients.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

E.4 | Principal exclusion criteria |
Patients are not eligible for participation in the study if they meet any of the following exclusion criteria: 1. Received TKI therapy within 7 days prior to receiving the first dose of ponatinib, or have not recovered (> grade 1 by NCI CTCAE, v. 4.0) from AEs (except alopecia) due to agents previously administered. Received other therapies as follows: a. For CP and AP patients, received hydroxyurea or anagrelide within 24 hours prior to receiving the first dose of ponatinib, interferon, cytarabine, or immunotherapy within 14 days, or any other cytotoxic chemotherapy, radiotherapy, or investigational therapy within 28 days prior to receiving the first dose of ponatinib. b. For BP patients, received chemotherapy within 14 days prior to the first dose of ponatinib. Otherwise 2a applies. c. For Ph+ ALL patients, received corticosteroids within 24 hours before the first dose of ponatinib, or vincristine within 7 days prior to the first dose of ponatinib, or received other chemotherapy within 14 days prior to the first dose of ponatinib. Otherwise, 2a applies. d. All patients are excluded if they have not recovered (> grade 1 by NCI CTCAE, v. 4.0) from AEs (except alopecia) due to agents previously administered.
3. Underwent autologous or allogeneic stem cell transplant < 60 days prior to receiving the first dose of ponatinib; any evidence of on-going graft-versus-host disease (GVHD), or GVHD requiring immunosuppressive therapy. 4. Take medications that are known to be associated with Torsades de Pointes. These medications are listed in Attachment B. 5. Require concurrent treatment with immunosuppressive agents, other than corticosteroids prescribed for a short course of therapy. 6. Have previously been treated with ponatinib. 7. Patient with CML CP are excluded if they are in CCyR. 8. Patients with CML AP, BP, or Ph+ ALL are excluded if they are in MaHR. 9. Have active central nervous system (CNS) disease as evidenced by cytology or pathology. In the absence of clinical CNS disease, lumbar puncture is not required. History itself of CNS involvement is not exclusionary if CNS has been cleared with a documented negative lumbar puncture. 10. Have significant or active cardiovascular disease, specifically including, but not restricted to: a. Myocardial infarction within 3 months prior to first dose of ponatinib, b. History of clinically significant atrial arrhythmia or any ventricular arrhythmia, c. Unstable angina within 3 months prior to first dose of ponatinib, d. Congestive heart failure within 3 months prior to first dose of ponatinib. 11. Have a significant bleeding disorder unrelated to CML or Ph+ ALL. 12. Have a history of pancreatitis or alcohol abuse. 13. Have uncontrolled hypertriglyceridemia (triglycerides >450 mg/dL). 14. Have malabsorption syndrome or other gastrointestinal illness that could affect absorption of orally administered ponatinib. 15. Have been diagnosed with another primary malignancy within the past 3 years (except for non-melanoma skin cancer or cervical cancer in situ, or controlled prostate cancer, which are allowed within 3 years). 16. Are pregnant or lactating. Women of childbearing potential must agree to effective contraception from the time of signing informed consent through the Follow-up Visit, approximately 30 days after last dose of ponatinib. 17. Underwent major surgery (with the exception of minor surgical procedures, such as catheter placement or BM biopsy) within 14 days prior to first dose of ponatinib. 18. Have ongoing or active infection (including known history of human immunodeficiency virus [HIV], hepatitis B virus [HBV], or hepatitis C virus [HCV]). Testing for these viruses is not required in the absence of history. 19. Suffer from any condition or illness that, in the opinion of the Investigator or the medical monitor, would compromise patient safety or interfere with the evaluation of the safety of the study drug.
