Summary

The researchers are doing this study to find out whether combining venetoclax with several different standard chemotherapy drugs used to treat acute lymphoblastic leukemia (ALL) in children is safe and effective in adults with newly diagnosed ALL. Participants in this study will be under the age of 60, and they will have T- or B-cell ALL.

Description

All patients will complete Induction I and II of the treatment regimens, consisting of several chemotherapy agents including Peg-ASP.

  • For Dose Level 1: Venetoclax will be administered at a dose of 100mg on day 5, 200mg on day 6 and 400mg on days 7-28 during Induction I. During Induction II, venetoclax will be administered at 400mg daily from days 1-14 and 29-42.
  • For Dose Level -1: Venetoclax will be administered at a dose of 100mg on day 5 and 200mg on days 6-28 during Induction I. During Induction II, venetoclax will be administered at 200mg daily from days 1-14 and 29-42.
  • Bone marrow aspirate and biopsy will be performed at day 14 of Induction I, after Induction I and Induction II for disease assessment.

For those who remain on study after Induction II, they will proceed to consolidation therapy. Consolidation blocks contain 2 Intensification blocks (22 days each) and 2 Re-Induction blocks (43 days each), consisting of several chemotherapy agents including Peg-ASP.

  • Venetoclax will be administered at a dose of 400mg daily (Dose Level 1) or 200mg daily (Dose Level -1) from days 1-22 during Intensification blocks, and from days 1-14 and 29-42 during Re-Induction blocks.
  • Bone marrow aspirate and biopsy will be performed after Re-Induction I and Re-Induction II for disease assessment.
  • Patients who relapse either with MRD or morphologically will be removed from study to pursue alternative therapy.
  • Patients who remain in MRD negative CR will remain on study and proceed to Maintenance.
  • Maintenance block contains 4-drug regimen (vincristine, oral methotrexate, oral mercaptopurine, and prednisone) for 2 years. No venetoclax will be administered during this block. Bone marrow aspirate and biopsy will be performed every 3 months during the Maintenance block. Patients who remain in MRD negative CR will remain on study to complete the study treatment. Patients who relapse either with MRD or morphologically will be removed from study to pursue alternative therapy.

Eligibility

Yes No Not Sure

Inclusion Criteria

Adult patients with newly diagnosed Philadelphia chromosome (Ph) negative ALL
Patients with T- or B-cell lymphoblastic lymphoma with no bone marrow involvement will also be eligible for the study
Age 18-60
ECOG performance status of 0-2
Adequate renal function as demonstrated by a calculated creatinine clearance of ≥ 60 ml/min
Adequate hepatic function as demonstrated by a total bilirubin ≤ 2.0 mg/dl (unless attributable to Gilbert's disease) and an alkaline phosphatase, AST, and ALT ≤ 4 times the upper limit of normal (unless clinically considered to be related to liver involvement with leukemia)
Patients with central nervous system (CNS) involvement by ALL are eligible and may receive concomitant treatment with radiation therapy and/or intrathecal chemotherapy in accordance with standard medical practice. For patients with CNS disease, dexamethasone may be temporarily administered instead of prednisone to reduce CNS pressure, at the discretion of the treating physician and after discussion with the MSK PI. Once dexamethasone is no longer needed, prednisone should be given as per protocol for 28 days
Negative serum pregnancy test in women of childbearing potential

Exclusion Criteria

CML in lymphoid blast crisis, mature B-cell (i.e. Burkitt's) lymphoma or mixed phenotype acute leukemia (MPAL)
Prior treatments for ALL, except any doses of corticosteroids and hydroxyurea or one dose of vincristine
Patients who received strong and/or moderate CYP3A inducers within 7 days prior to the initiation of study treatment
Unstable angina and/or MI or stroke within 6 months prior to screening, and/or impaired cardiac function with EF <40% or NYHA class III/IV
Pregnant or lactating women. Women and men of childbearing age should use effective contraception while on this study and continue for 1 year after all treatment is finished
Patients with HIV or active hepatitis B or hepatitis C infection are ineligible
Patients with concurrent active malignancies as defined by malignancies requiring any therapy other than expectant observation or hormonal therapy, with the exception of squamous and basal cell carcinoma of the skin, in situ cervical cancer, adequately treated stage I/II cancer from which the patient is current in complete remission, or any other cancer from which the patient has been disease free for five years
