This is an interventional treatment trial for Accelerated Phase Chronic Myelogenous Leukemia, BCR-ABL1 Positive Read More

Inclusion Criteria:

• Diagnosis of one of the following:

  • Previously untreated Ph-positive ALL (either t[9;22] and/or bcr-abl positive) (includes patients initiated on first course of hyper-CVAD before cytogenetics known) or with lymphoid accelerated or blast phase chronic myelogenous leukemia (CML)

  • Previously treated Ph-positive ALL or CML (in accelerated phase or blast phase), after 1-2 courses of chemotherapy with or without other tyrosine kinase inhibitors (TKIs)

    • If they achieved complete response (CR), they are assessable only for event-free and overall survival, or
    • If they failed to achieve CR, they are assessable for CR, event-free, and overall survival
• Performance status =< 2 (Eastern Cooperative Oncology Group [ECOG] scale)
• Total serum bilirubin =< 1.5 x upper limit of normal (ULN), unless due to Gilbert's syndrome
• Alanine aminotransferase (ALT) =< 2 x ULN
• Aspartate aminotransferase (AST) =< 2.5 x ULN
• Serum lipase and amylase =< 1.5 x ULN
• For females of childbearing potential, a negative pregnancy test must be documented prior to randomization
• Female and male patients who are fertile must agree to use an effective form of contraception with their sexual partners from randomization through 4 months after the end of treatment
• Adequate cardiac function as assessed clinically by history and physical examination
• Signed informed consent

Exclusion Criteria:

• Active serious infection not controlled by oral or intravenous antibiotics
• Known active hepatitis B; patients with chronic hepatitis B who are on appropriate viral suppressive therapy may be allowed after discussion with the principal investigator (PI)
• History of acute pancreatitis within 1 year of study or history of chronic pancreatitis
• History of alcohol abuse
• Uncontrolled hypertriglyceridemia (triglycerides > 450 mg/dL)
• Active secondary malignancy other than skin cancer (e.g., basal cell carcinoma or squamous cell carcinoma) that in the investigator's opinion will shorten survival to less than 1 year
• Active grade III-V cardiac failure as defined by the New York Heart Association criteria

• Clinically significant, uncontrolled, or active cardiovascular disease, specifically including, but not restricted to:

  • Any history of myocardial infarction (MI), stroke, or revascularization
  • Unstable angina or transient ischemic attack prior to enrollment
  • Congestive heart failure prior to enrollment, or left ventricular ejection fraction (LVEF) less than lower limit of normal per local institutional standards prior to enrollment
  • Diagnosed or suspected congenital long QT syndrome
  • Any history of clinically significant atrial or ventricular arrhythmias (such as atrial fibrillation, ventricular tachycardia, ventricular fibrillation, or torsades de pointes) as determined by the treating physician
  • Prolonged corrected QT (QTc) interval on pre-entry electrocardiogram (> 470 msec) unless corrected after electrolyte replacement
  • Any history of venous thromboembolism including deep venous thrombosis or pulmonary embolism
  • Uncontrolled hypertension (diastolic blood pressure > 90 mmHg; systolic > 140 mmHg); patients with hypertension should be under treatment on study entry to effect blood pressure control
• Patients currently taking drugs that are generally accepted to have a risk of causing torsades de pointes (unless these can be changed to acceptable alternatives)
• Taking any medications or herbal supplements that are known to be strong inhibitors of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) within at least 14 days before the first dose of ponatinib
• Prior history of treatment with ponatinibfor > 1 month; patient who has been treated with ponatinib for 1 month prior starting the treatment is eligible
• Treatment with any investigational antileukemic agents or chemotherapy agents in the last 7 days before study entry, unless full recovery from side effects has occurred or patient has rapidly progressive disease judged to be life-threatening by the investigator; patient who has been treated with ponatinib for 1 month prior starting the treatment is eligible
• Pregnant and lactating women will not be eligible; women of childbearing potential should have a negative pregnancy test prior to entering on the study and be willing to practice methods of contraception; women do not have childbearing potential if they have had a hysterectomy or are postmenopausal without menses for 12 months; in addition, men enrolled on this study should understand the risks to any sexual partner of childbearing potential and should practice an effective method of birth control

• History of significant bleeding disorder unrelated to cancer, including:

  • Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease)
  • Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
• Patients with documented significant pleural or pericardial effusions unless they are thought to be secondary to their leukemia
