A Phase II Study of Blinatumomab and POMP (Prednisone, Vincristine, Methotrexate, 6-Mercaptopurine) for Patients ≥ 65 Years of Age With Newly Diagnosed Philadelphia-Chromosome Negative (Ph-) Acute Lymphoblastic Leukemia (ALL) and of Dasatinib, Prednisone and Blinatumomab for Patients ≥ 65 Years of Age With Newly Diagnosed Philadelphia-Chromosome Positive (Ph+) ALL, Relapsed/Refractory Philadelphia-Chromosome Positive (Ph+) ALL, and Philadelphia-Chromosome-Like Signature (Ph-Like) ALL With Known or Presumed Activating Dasatinib-Sensitive Mutations or Kinase Fusions (DSMKF)
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.
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).
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.
ADDITIONAL TRANSLATIONAL MEDICINE OBJECTIVES:
I. To estimate the incidence of the Ph-like signature in elderly patients (>= 65 years of age) with newly diagnosed Philadelphia-chromosome negative ALL.
II. To estimate the incidence of the various tyrosine-kinase fusions, making up the Ph-like signature in elderly patients with newly diagnosed Philadelphia-chromosome negative ALL.
III. To evaluate outcomes (event free survival [EFS] and overall survival [OS]) in patients with the Ph-like signature versus those without the Ph-like signature in Ph-negative ALL.
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. (Closed to accrual 06/29/17)
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.
