About
This phase Ib/II trial studies the side effects and best dose of venetoclax and how well it works when given together with vincristine in treating patients with T-cell or B-cell acute lymphoblastic leukemia that has come back (recurrent) or does not respond to treatment (refractory). Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as vincristine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax together with vincristine may work better in treating patients with acute lymphoblastic leukemia compared to vincristine alone.
Full description
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose of venetoclax in combination with vincristine liposomal (liposomal vincristine)/vincristine sulfate in patients with relapsed or refractory T-cell and B-cell acute lymphoblastic leukemia (ALL). (Phase I) II. Safety assessment and toxicity characterization after treatment of venetoclax in combination with liposomal vincristine in patients with relapsed or refractory T-cell and B-cell ALL. (Phase I) III. To determine the preliminary efficacy of venetoclax in combination with liposomal vincristine/vincristine sulfate to induce complete remission (CR)+ incomplete complete remission (CRi) in patients with relapsed or refractory T-cell and B-cell ALL. (Phase II)
SECONDARY OBJECTIVES:
I. To determine the progression free survival, overall survival and toxicity after the combination treatment in patients with relapsed or refractory T-cell and B-cell ALL. (Phase II) II. To determine the rate of minimal residual disease (MRD) negativity rate of the combination. (Phase II)
EXPLORATORY/CORRELATIVE OBJECTIVES:
I. To determine if genetic signature as determined by next generation sequencing can predict response to combination. (Phase II) II. To determine if immunophenotype of ALL is associated with response to combination. (Phase II) III. To determine if the BH3 profile is associated with response to combination. (Phase II) IV. To determine if relative expression of BCL-2 measure by flow cytometry is associated with response to combination. (Phase II)
OUTLINE: This is a phase Ib, dose-escalation study of venetoclax followed by a phase II study.
PHASE Ib: Patients receive venetoclax orally (PO) once daily (QD) on days 1-42 of cycle 1 and days 43-70 of cycle 2. Patients also receive vincristine liposomal intravenously (IV) over 1 hour weekly for 4 weeks starting on day 15 of cycle 1. Patients who achieve at least a stable disease response may continue treating at the discretion of the treating physician in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection throughout the trial. Patients may also undergo computed tomography (CT) and/or positron emission tomography (PET) scan as well as a lumbar puncture as clinically indicated.
PHASE II: Patients receive venetoclax PO QD on days 1-28 of each cycle. Patients also receive vincristine liposomal IV over 1 hour weekly for 4 weeks on day 1 of each cycle or vincristine sulfate IV weekly on days 1, 8, 15, and 22 of cycle 1 and once every 4 weeks on day 1 of each subsequent cycle. Cycles repeat every 28 days. Patients who achieve at least a stable disease response may continue treating at the discretion of the treating physician in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection throughout the trial. Patients may also undergo CT and/or PET scan as well as a lumbar puncture as clinically indicated.
After completion of study treatment, patients are followed up every 6 months for 5 years.
