• Other clinically significant vascular and 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 Ponatinib (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
• History of or current autoimmune disease.
• Known hypersensitivity to immunoglobulins or to any other component of the study drug formulation.
• Active malignancy other than ALL with the exception of basal cell or squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix.
