Subcutaneous Blinatumomab for Treatment of Adult Patients With CD19-Positive Mixed Phenotype Acute Leukemia (MPAL)

This is a multicenter, non-randomized, open-label, phase II study evaluating blinatumomab administered subcutaneously in adult subjects with CD19+ MPAL. This trial consists of three cohorts of patients with CD19-positive MPAL, categorized as follows: 1. Cohort A: Newly diagnosed CD19+ MPAL in untreated patients who are either ≥ 75 years of age or have at least one coexisting condition precluding intensive chemotherapy. 2. Cohort B: Patients with CD19+ MPAL who have achieved complete remission (CR, CRh, or CRi) following at least one line of treatment but have detectable measurable residual disease (MRD) at a level of ≥ 0.1%, assessed using an assay with a minimum sensitivity of 0.01%. 3. Cohort C: Patients with CD19+ MPAL with morphologic relapsed or refractory (R/R) disease following at least one prior line of treatment. The Primary Objectives for each cohort are for Cohort A: to evaluate the efficacy of SC-blinatumomab in treatment; for Cohort B: to assess the ability of SC-blinatumomab to achieve MRD-negative CR; for Cohort C: to determine the efficacy of SC-blinatumomab in inducing CR, CRh, or CRi in patients. At specified time points, subjects will undergo the following procedures: collection of informed consent, medical history, demographics, ECOG performance, and physical exam including vital signs as well as neurological examination including examination of writing ability. Subjects will provide samples for complete blood count with differential and blood chemistry profile, have a bone marrow aspiration and biopsy and lumbar puncture will be performed per protocol or if clinically indicated, and/or ECG, Echocardiography, pulmonary function test will be performed only if medically indicated. The subcutaneous treatment will be given in both the inpatient and outpatient setting. For an individual subject the length of participation includes up to a 3-week screening period, up to a 13-month treatment period, and a safety follow-up visit (30 days after the last dose of study treatment), and a follow-up period.

CD19/CD22 Chimeric Antigen Receptor (CAR) T Cells With or Without NKTR-255 in Adults With Recurrent or Refractory B Cell Malignancies

This phase I trial studies the side effects of CD19/CD22 chimeric antigen receptor (CAR) T cells when given together with chemotherapy and NKTR-255, and to see how well they work in treating patients with CD19 positive B acute lymphoblastic leukemia that has come back or does not respond to treatment. A CAR is a genetically-engineered receptor made so that immune cells (T cells) can attack cancer cells by recognizing and responding to the CD19/CD22 proteins. These proteins are commonly found on diffuse large B-cell lymphoma and B acute lymphoblastic leukemia. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, 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. NKTR-255 is an investigational IL-15 receptor agonist designed to boost the immune system's natural ability to fight cancer. Giving CD19/CD22-CAR T cells and chemotherapy in combination with NKTR-255 may work better in treating patients with diffuse large B-cell lymphoma or B acute lymphoblastic leukemia.

Modified Immune Cells (CD19/CD20 CAR-T Cells) in Treating Patients With Recurrent or Refractory B-Cell Lymphoma or Chronic Lymphocytic Leukemia

This phase I trial studies the side effects and best dose of CD19/CD20 chimeric antigen receptor (CAR) T-cells when given together with chemotherapy, and to see how effective they are in treating patients with non-Hodgkin's B-cell lymphoma or chronic lymphocytic leukemia that has come back (recurrent) or has not responded to treatment (refractory). In CAR-T cell therapy, a patient's white blood cells (T cells) are changed in the laboratory to produce an engineered receptor that allows the T cell to recognize and respond to CD19 and CD20 proteins. CD19 and CD20 are commonly found on non-Hodgkin?s B-cell lymphoma and chronic lymphocytic leukemia cells. Chemotherapy drugs such as fludarabine phosphate and cyclophosphamide can control cancer cells by killing them, by preventing their growth, or by stopping them from spreading. Combining CD19/CD20 CAR-T cells and chemotherapy may help treat patients with recurrent or refractory B-cell lymphoma or chronic lymphocytic leukemia.

Study of CD19/CD22 Chimeric Antigen Receptor (CAR) T Cells in Children and Young Adults w/ Recurrent or Refractory B Cell Malignancies

Pembrolizumab and Blinatumomab in Treating Participants With Recurrent or Refractory Acute Lymphoblastic Leukemia

This phase I/II studies the side effects of pembrolizumab and blinatumomab and to see how well they work in treating participants with acute lymphoblastic leukemia that has come back or has not responded to the treatment. Monoclonal antibodies, such as pembrolizumab and blinatumomab, may interfere with the ability of tumor cells to grow and spread.
