This phase II trial studies how well sapanisertib works in treating patients with acute lymphoblastic leukemia that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Sapanisertib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVES: I. To determine the complete hematologic response (CR)/complete response incomplete (CRi) rate when sapanisertib (MLN0128 \[TAK-228\]) is administered to adult patients with relapsed/refractory acute lymphoblastic leukemia (ALL). SECONDARY OBJECTIVES: I. To determine the overall response rate (CR, CRi/partial response (PR)/morphologic leukemia free state \[MLFS\]). II. To determine the CR/CRi duration when MLN0128 (TAK-228) is administered to adult patients with relapsed/refractory ALL. III. To determine the frequency of proceeding to allogeneic stem cell transplantation (SCT) for patients with relapsed/refractory ALL who achieve a response on MLN0128 (TAK-228). IV. To determine the overall survival for relapsed/refractory ALL patients on MLN0128 (TAK-228). TERTIARY OBJECTIVES: I. To examine the pharmacokinetics of MLN0128 (TAK-228) in ALL patients. II. To assess whether phosphorylation of the mTOR substrate 4EBP1 decreases in leukemic blasts harvested from the bone marrow on day 8 compared to baseline. III. To assess in an exploratory fashion whether MLN0128 (TAK-228) enhances expression of the pro-apoptotic proteins Bim and Puma in marrow ALL cells. IV. To assess in an exploratory fashion whether Mcl-1 levels decrease in blast cells during MLN0128 (TAK-228) treatment. V. To assess in an exploratory fashion whether a) the phospho-protein pattern at baseline or b) MLN0128 (TAK-228)-associated changes in the phospho-protein pattern differs between ALL samples that respond to therapy and those that do not. OUTLINE: Patients receive sapanisertib orally (PO) daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients who are non-responders and in PR at the end of course 4 may receive sapanisertib PO daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months.

Complete Response (CR or CRi)
Complete response rate, defined to be a complete hematologic response (CR) or complete response incomplete (CRi) noted as the objective status at any time during treatment. A CR is defined as having less than 5% blasts in a non-hypocellular marrow with a granulocyte count of 1 x109/L (or above), and a platelet count of 100 x109/L (or higher) and absence of peripheral blood blasts with complete resolution of any extra medullary disease. A patient is defined as having a CRi if they meet all CR criteria except for residual neutropenia (ANC\<1 x109/L) or thrombocytopenia (platelets\<100 x109/L). A CR or CRi will be considered synonymous with "success". The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Ninety-five percent exact binomial confidence intervals for the true success proportion will be calculated.
Time frame: 61 days
Overall Response
ORR will be estimated by the total number of complete or partial responses (CR, CRi or PR), or morphologic leukemia free state \[MLFS\]) divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true overall response rate will be calculated. A CR is defined as having less than 5% blasts in a non-hypocellular marrow with a granulocyte count of 1 x109/L (or above), and a platelet count of 100 x109/L (or higher) and absence of peripheral blood blasts with complete resolution of any extra medullary disease. A patient is defined as having a CRi if they meet all CR criteria except for residual neutropenia (ANC\<1 x109/L) or thrombocytopenia (platelets\<100 x109/L). A Partial Response (PR) is defined as the presence of trilineage hematopoiesis in the bone marrow with recovery of ANC and platelet count to above levels, but with 5-25% bone marrow blasts and ≥50% decrease in bone marrow blast percentage from baseline.
Time frame: 61 days
Duration of Complete Response
The distribution of duration of complete response will be estimated using the method of Kaplan-Meier.
Time frame: 0 days
Frequency of Proceeding to Allogeneic Stem Cell Transplantation (SCT) After Achieving Response (Complete Hematologic Response [CR]/Complete Response Incomplete [CRi] Partial Response [PR], or Morphologic Leukemia Free State [MLFS]) to Sapanisertib
The frequency is estimated by the number of patients who proceed to allogeneic SCT after achieving response divided by the total number of evaluable patients who achieved a response. All evaluable patients who achieved a response will be used for this analysis. Exact binomial 95% confidence intervals for the true overall response rate will be calculated.
Time frame: 0 days
Overall Survival
The distribution of survival time will be estimated using the method of Kaplan-Meier.
Time frame: 23 months
Incidence of Adverse Events, Measured Per National Cancer Institute Common Terminology Criteria for Adverse Events Version 4
The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. For this endpoint, we are reporting the maximum grade adverse event per patient.
Time frame: 91 days
