Brief Summary:
This phase I/II trial studies the side effects and best dose of venetoclax and how well it works in combination with low-intensity chemotherapy in patients with B- or T-cell acute lymphoblastic leukemia that has not responded to treatment or that has come back. Venetoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, including vincristine, cyclophosphamide, dexamethasone, rituximab, methotrexate, and cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax with low-intensity chemotherapy may work better in treating patient with B- or T-cell acute lymphoblastic leukemia.

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) (Phase I) [ Time Frame: Up to 28 days ]
    The MTD is the highest dose level in which < 2 patients of 6 develop first cycle dose-limiting toxicity (DLT).

  2. DLT (Phase I) [ Time Frame: Up to 28 days ]
    A non-hematologic DLT is defined as a clinically significant (as assessed by treating physician) grade 3 or 4 adverse event or abnormal laboratory value (according to Common Terminology Criteria for Adverse Events [CTCAE] criteria). Toxicity type, severity and attribution will be summarized for each patient using frequency tables.

Secondary Outcome Measures :
  1. Overall response rate (Phase II) [ Time Frame: Up to 56 days (2 courses) ]
    Will be defined as the percentage of patients achieving a complete response (CR) or CR with inadequate count recovery (CRi). Will estimate the overall response (OR) for the combination treatment, along with the 95% credible interval.

  2. Minimal residual disease (MRD) negativity [ Time Frame: Up to 4 years ]
    Will be summarized using descriptive statistics such as mean, standard deviation, median and range.

  3. Duration of response (DOR) [ Time Frame: Up to 4 years ]
    Will be summarized using descriptive statistics such as mean, standard deviation, median and range. The association between response and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.

  4. Event-free survival (EFS) [ Time Frame: From the first day of treatment until any failure (resistant disease, relapse, or death), assessed up to 4 years ]
    The association between response and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.

  5. Overall survival (OS) [ Time Frame: From the first day of treatment to time of death from any cause, assessed up to 4 years ]
    The association between response and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.

  6. Incidence of adverse events [ Time Frame: Up to 4 years ]
    Will be summarized using descriptive statistics such as mean, standard deviation, median and range.

Other Outcome Measures:
  1. Apoptotic protein expression and Bcl-2 dependency [ Time Frame: Up to 4 years ]
    Apoptotic protein expression and Bcl-2 dependency will be correlated on response and resistance to the combination regimen.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with relapsed/refractory B- or T-cell ALL
  • Performance status =< 3 (Eastern Cooperative Oncology Group [ECOG] Scale)
  • Total serum bilirubin =< 2 x upper limit of normal (ULN), unless due to Gilbert's syndrome, in which case patients are eligible as long as direct bilirubin =< 2 x ULN
  • Alanine aminotransferase (ALT) =< 3 x ULN, unless due to disease involvement of the liver or hemolysis, in which case an ALT =< 10 x ULN is acceptable
  • Aspartate aminotransferase (AST) =< 3 x ULN, unless due to disease involvement of the liver or hemolysis, in which case an AST =< 10 x ULN is acceptable
  • Creatinine clearance >= 30 mL/min
  • For females of childbearing potential, a negative pregnancy test must be documented within 1 week of starting treatment
  • Female and male patients who are fertile must agree to use an effective form of contraception (birth control methods while on study, such as birth control pills or injections, intrauterine devices [IUDs]), or double-barrier methods (for example, a condom in combination with spermicide) with their sexual partners for 4 months after the end of treatment
  • Signed informed consent

Exclusion Criteria:

  • Patients with Philadelphia chromosome-positive ALL or Burkitt leukemia
  • Active serious infection not controlled by oral or intravenous antibiotics
  • 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
  • Known hepatitis B or C infection, or known seropositivity for human immunodeficiency virus (HIV)
  • Active grade III-V cardiac failure as defined by the New York Heart Association Criteria
  • Patients with a cardiac ejection fraction (as measured by either multigated acquisition [MUGA] or echocardiogram) < 40%
  • Received moderate or strong CYP3A inhibitors or strong CYP3A inducers within 7 days of starting venetoclax
  • Consumed grapefruit, grapefruit products, Seville oranges, or star fruit within 3 days prior to starting venetoclax
  • Prior history of treatment with venetoclax
  • 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. Exception: Treatment with hydroxyurea and/or dexamethasone are allowed prior to study treatment, without window of exclusion
  • 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)
