About

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.

Full description

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.

Enrollment: 16 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• World Health Organization (WHO)-defined acute lymphoblastic leukemia and either:

  • Relapsed after achieving remission
  • Refractory to therapy

• Bone marrow blasts of at least 10%

• At least 4 weeks away from any previous antineoplastic or investigational agent; patients may receive hydroxyurea or glucocorticoids for suppression of leukocytosis, but these must be stopped at least 24 hours (h) prior to initiation of therapy

• Eastern Cooperative Oncology Group (ECOG) performance status =< 2

• Life expectancy of > 2 months

• Total bilirubin =< 1.5 x institutional upper limit of normal

• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal

• Creatinine =< 1.5 x institutional upper limit of normal

• Fasting blood glucose (FBG) < 130 mg/dL

• Hemoglobin A1C (HbA1C) < 7.0%

• Relapse after SCT is allowed but no active graft-versus-host disease (GVHD) as per treating physician; also must not exceed the number of prior induction regimens listed above; SCT does not count as line of therapy

• Negative serum pregnancy test result; Note: women of child-bearing potential and men must agree to use 1 highly effective method of contraception and 1 additional effective (barrier) method, at the same time, from the time of signing the informed consent through 90 days (or longer, as mandated by local labeling [e.g. United States product insert (USPI), Summary of Product Characteristics (SmPC), etc]) after the last does of study drug; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use highly effective barrier contraception prior to the study, for the duration of study participation, and 4 months after completion of MLN0128 (TAK-228) administration

• Ability to understand and the willingness to sign a written informed consent document

• No prior therapy with mTOR inhibitors except for rapalog treatment as part of graft-versus-host (GVH) prophylaxis or treatment

• Human immunodeficiency virus (HIV) infected patients (if HIV positive)

  • HIV infected individuals are eligible provided they meet all the protocol eligibility criteria in addition to the following:

    • No history of acquired immune deficiency syndrome (AIDS) defining illness other than a historic CD4+ T-cell nadir < 200/mm^3

    • Prior to leukemia diagnosis, the HIV disease was uncomplicated as evidenced by:

      • The CD4+ T-cell counts were generally in excess of 300/mm^3
      • The HIV viral loads were less than 200 copies/ml if on anti-HIV therapy
      • If the HIV is newly diagnosed or there is no history of using anti-HIV therapy, there are no AIDS defining conditions or other HIV-related symptoms
      • Zidovudine is not allowed as part of the anti-HIV therapy

Exclusion criteria

• Patients who have had chemotherapy or radiotherapy =< 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier; treatment with glucocorticoids, hydroxyurea, and tyrosine kinase inhibitors is allowed up to 24 hour prior to initiation of therapy
• Patients with white blood cell (WBC) > 30,000 are not eligible to start therapy; however, it is permissible to use glucocorticoids and/or hydroxyurea to diminish peripheral WBC to less than 30,000 provided these agents are stopped at least 24 hours prior to the first dose of MLN0128 (TAK-228)
