Blinatumomab and Combination Chemotherapy or Dasatinib Prednisone and Blinatumomab in Treating Older Patients With Acute Lymphoblastic Leukemia


Brief description of study

This phase II trial studies the side effects and how well blinatumomab and combination chemotherapy or dasatinib, prednisone, and blinatumomab work in treating older patients with acute lymphoblastic leukemia. Immunotherapy with blinatumomab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as prednisone, vincristine sulfate, methotrexate, and mercaptopurine, 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. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab with combination chemotherapy or dasatinib and prednisone may kill more cancer cells.

Detailed Study Description

PRIMARY OBJECTIVES:

I. To evaluate the 3-year survival rate in elderly patients with newly diagnosed Philadelphia (Ph)-negative acute lymphoblastic leukemia (ALL) treated with blinatumomab followed by POMP (prednisone, vincristine sulfate, methotrexate, and mercaptopurine) maintenance.

II. To evaluate in a preliminary manner (feasibility study) the safety of dasatinib-steroid based induction followed by blinatumomab treatment in combination with dasatinib followed by dasatinib-based maintenance in patients with newly diagnosed Ph-positive ALL, relapsed/refractory Ph-positive ALL, and Ph-like dasatinib-sensitive mutations or kinase fusions (DSMKF) ALL (newly-diagnosed relapsed or refractory).

SECONDARY OBJECTIVES:

I. To evaluate toxicities in these patient populations treated with these regimens.

II. To estimate the rates of complete response (CR), complete remission with incomplete count recovery (CRi) and disease-free survival in Ph-negative patients.

III. To estimate disease-free and overall survival in Ph-positive ALL and Ph-like DSMKF ALL.

IV. To estimate in each cohort the rate of minimal residual disease (MRD) negativity, and the time to achieve MRD negativity (exploratory analysis).

V. To determine whether anti-idiotype antibodies directed against blinatumomab develop with blinatumomab treatment in this study.

OUTLINE: Patients are assigned to 1 of 2 treatment cohorts according to Philadelphia chromosome status.

COHORT I (PHILADELPHIA CHROMOSOME NEGATIVE PATIENTS):

INDUCTION: Patients receive blinatumomab intravenously (IV) continuously over 24 hours on days 1-28 in the absence of disease progression or unacceptable toxicity.

RE-INDUCTION: Patients not achieving CR or CRi after Induction, receive blinatumomab IV continuously over 24 hours on days 1-28 in the absence of disease progression or unacceptable toxicity.

POST-REMISSION: Patients receive blinatumomab IV continuously over 24 hours on days 1-28. Treatment repeats every 42 days for 3 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive prednisone orally (PO) on days 1-5, vincristine sulfate IV on day 1, mercaptopurine PO on days 1-28, and methotrexate PO on days 1, 8, 15, and 22. Treatment repeats every 28 days for 18 cycles in the absence of disease progression or unacceptable toxicity.

COHORT II (PHILADELPHIA CHROMOSOME POSITIVE PATIENTS):

INDUCTION: Patients receive dasatinib PO twice daily (BID) on days 1-84 and prednisone PO on days 1-24 with tapering on days 25-32 in the absence of disease progression or unacceptable toxicity.

RE-INDUCTION: Patients receive blinatumomab IV continuously over 24 hours on days 1-28. Treatment repeats every 42 days for 2 cycles in the absence of disease progression or unacceptable toxicity.

POST-REMISSION: Patients receive blinatumomab IV continuously over 24 hours on days 1-28 and dasatinib PO once daily (QD) on days 1-42. Treatment repeats every 42 days for 3 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive dasatinib PO BID on days 1-28 and prednisone PO on days 1-5. 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 for 2 years, every 6 months for 2 years, and then annually until 10 years from initial registration.
