Brief Summary

This phase II trial studies how well ibrutinib and blinatumomab work in treating patients with B acute lymphoblastic leukemia that has come back or is not responding to treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as blinatumomab, may interfere with the ability of cancer cells to grow and spread. Giving ibrutinib and blinatumomab may work better in treating patients with relapsed or refractory B acute lymphoblastic leukemia.

Conditions

Philadelphia Chromosome Positive; Adult B Acute Lymphoblastic Leukemia

• Overall Response Rate (ORR).

  Up to 8 months from start of treatment.

• Overall Survival (OS).

  From the time of first study drug administration until date of death from any cause, assessed for up to about 15.6 months.

• Proportion of Patients Bridged to Allogeneic Hematopoietic Cell Transplant (Allo-HCT or CAR-T.

  Time from start of treatment to date of hematopoietic cell transplant assessed for up to 8 months.

Study Arms (1)

Treatment (ibrutinib, blinatumomab)

EXPERIMENTAL

INDUCTION THERAPY: Patients receive ibrutinib PO QD on days 1-49 of course 1 and days 1-42 of course 2, and blinatumomab IV on days 8-35 of course 1 and days 1-28 of course 2 in the absence of disease progression or unacceptable toxicity. CONSOLIDATION THERAPY: Patients with CR/CRi after Induction Therapy receive ibrutinib PO QD on days 1-42 and blinatumomab IV on days 1-28. Treatment repeats every 42 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients receive ibrutinib PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

• Prothrombin time (PT)/international normalized ratio (INR) =\< 1.5 x ULN and partial thromboplastin time (PTT) (activated partial thromboplastin time \[aPTT\]) =\< 1.5 x ULN (unless B-ALL related)
• Karnofsky performance status (KPS) performance status of 60% or greater
• Ability to understand and willingness to sign an informed consent form
• Ability to adhere to the study visit schedule and other protocol requirements
• Female subjects who are of non-reproductive potential (i.e., post-menopausal by history - no menses for \>= 1 year; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy); female subjects of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the first study drug administration
• Male and female subjects who agree to use both a highly effective methods of birth control (e.g., condoms, implants, injectables, combined oral contraceptives, some intrauterine devices \[IUDs\], complete abstinence, or sterilized partner) and a barrier method (e.g. condoms, vaginal ring, sponge, etc) during the period of therapy and for 90 days after the last dose of study drug
• Eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of ibrutinib or blinatumomab will be determined following review of their case by the investigator

You may not qualify if:

• Diagnosis of T acute lymphoblastic leukemia (T-ALL) or Burkitt's leukemia/lymphoma
• Patients with current evidence of active central nervous system (CNS) leukemia
• History of treatment with ibrutinib or blinatumomab
• Investigational therapy, chemotherapy, immunotherapy, radiotherapy, or systemic graft versus host disease (GVHD) therapy within two weeks or five half-lives (whichever is shorter); steroids, hydroxyurea and/or leukapheresis are allowed to control blast count prior to the first dose of study drug
• Prior allo-HCT less than three months from the time of enrollment
• Any active acute GVHD or chronic GVHD greater than grade 1
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to ibrutinib and blinatumomab or other agents used in this study
