A Phase Ib Study of the Combination of Venetoclax With Chemotherapy as Frontline Therapy in Older Patients and Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia

Description

This research study is studying a medication called Venetoclax and a chemotherapy regimen as a possible treatment for Acute Lymphoblastic Leukemia. The drugs involved in this study are: * Venetoclax * Standard Chemotherapy (which includes cyclophosphamide, vincristine, doxorubicin, dexamethasone, methotrexate, 6-mercaptopurine, etoposide, and cytarabineThis research study is a Phase I clinical trial, which tests the safety of an investigational drug and drug combination and also tries to define the appropriate dose of the investigational drug and drug combination to use for further studies. "Investigational" means that the drug and drug combination is being studied. The FDA (the U.S. Food and Drug Administration) has not approved Venetoclax for this specific disease, but it has been approved for other uses. Venetoclax is an inhibitor of Bcl-2. Bcl-2 is critical for keeping cancer cells alive. By inhibiting Bcl-2, venetoclax promotes cancer cell death. This drug is currently being

Women of non- childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy. Men who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 30 days following the last dose of study drug * Patients or their legally authorized representative must provide written informed consent Exclusion Criteria: * Ph-positive ALL, Burkitt's leukemia/lymphoma, or lymphoblastic lymphoma * Patient is pregnant or breastfeeding * Patients with uncontrolled infection * Hepatitis B or C infection, or known seropositivity for human immunodeficiency virus (HIV) * Major surgery or radiation therapy within 4 weeks prior to the first study dose * Systemic chemotherapy/radiotherapy/investigational therapy within 14 days (with the exception of hydroxyurea and/or dexamethasone, or one dose of cytarabine) prior to starting therapy * Symptomatic or untreated leptomeningeal disease or spinal cord compression * Patients with active heart disease (New York Heart Association (NYHA) class 3-4 as assessed by history and physical examination, unstable angina/stroke/myocardial infarction within the last 6 months) * Patients with a cardiac ejection fraction (as measured by either Multi Gated Acquisition (MUGA) or echocardiogram (EKG)) \<40% * History of another primary invasive malignancy that has not been definitively treated or in remission for at least 2 years. Patients with non-melanoma skin cancers or with carcinomas in situ are eligible regardless of the time from diagnosis (including concomitant diagnoses) * Concurrent use of warfarin * Received Cytochrome P450 3A (CYP3A) inhibitors (such as fluconazole, ketoconazole, voriconazole, and clarithromycin) within 3 days of starting venetoclax; received strong CYP3A inducers (such as rifampin, rifabutin, phenytoin, carbamazepine, and St. John's Wort) within 3 days of starting venetoclax * Consumed grapefruit, grapefruit products, Seville oranges, or star fruit within 3 days prior to starting venetoclax * Prior treatment with venetoclax * Malabsorption syndrome or other conditions that preclude enteral route of administration * Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that in the opinion of the investigator may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and/or would make the patient inappropriate for enrollment into this study
