  • INCLUSION CRITERIA:
  • Diagnosis

    • Patient must have a B cell ALL (inclusive of CML with ALL transformation) or lymphoma and must have relapsed or refractory disease after at least one standard chemotherapy regimen and one salvage regimen. In view of the PI and the primary oncologist, there must be no available alternative curative therapies and subjects must be either ineligible for allogeneic stem cell transplant (SCT), have refused SCT, recurred after SCT, or have disease activity that prohibits SCT at the time of enrollment. Patients who have undergone autologous SCT will be eligible, and patients that have undergone allogeneic SCT will be eligible if, in addition to meeting other eligibility criteria, they have no evidence of GVHD and have been without immunosuppressive agents for at least 30 days. Patients with Philadelphia chromosome + ALL must have failed prior tyrosine kinase inhibitor.
    • Patients must have measurable or evaluable disease at the time of enrollment, which may include any evidence of disease including minimal residual disease detected by flow cytometry, cytogenetics, or polymerase chain reaction (PCR) analysis.

  • CD22/CD19 Expression

    --CD19 expression must be detected on greater than 15% of the malignant cells by immunohistochemistry or greater than 90% by flow cytometry. The choice of whether to use flow cytometry or immunohistochemistry will be determined by what is the most easily available tissue sample in each patient. In general, immunohistochemistry will be used for lymph node biopsies, flow cytometry will be used for peripheral blood and bone marrow samples. CD22+ B cell malignancy is required and CD22 expression levels will be documented when available, but a specific level of expression is not an eligibility requirement; it may be documented as positive or negative.

    --Greater than or equal to 3 years of age (and at least 15 kg) and less than or equal to 39 years of age at time of enrollment (greater than or equal to 3 years to less than or equal to 39 years). NOTE: The first patient in each dose cohort must be greater than or equal to 18 years of age.

  • Clinical Performance

    --Clinical performance status: Patients greater than or equal to 16 years of age: Karnofsky greater than or equal to 50%; Patients < 16 years of age: Lansky scale greater than or equal to 50%. Subjects who are unable to walk because of paralysis, but who are upright in a wheelchair will be considered ambulatory for the purpose of calculating the performance score.

  • Patients must have adequate organ and marrow function as defined below:

    • leukocytes greater than or equal to 750/mcL*

    • b. Positive for Hepatitis B surface antigen (HbsAG).
    • c. Evidence of active Hepatisis C (evidenced by detectable HCV RNA)
  • Uncontrolled, symptomatic, intercurrent illness including but not limited to infection, congestive heart failure, unstable angina pectoris, cardiac arrhythmia, psychiatric illness, or social situations that would limit compliance with study requirements or in the opinion of the PI would pose an unacceptable risk to the subject;
  • Second malignancy other than in situ carcinoma of the cervix, unless the tumor was treated with curative intent at least two years previously and subject is in remission;

5. Study Description

Brief Summary
Background: B-cell leukemias and lymphomas are cancers that are often difficult to treat. The primary objective of this study is to determine the ability to take a patient's own cells (T lymphocytes) and grow them in the laboratory with the CD19/CD22-CAR receptor gene through a process called 'lentiviral transduction (also considered gene therapy) and growing them to large numbers to use as a treatment for hematologic cancers in children and young adults.. Researchers want to see if giving modified CD19/CD22-CAR T cells to people with these cancers can attack cancer cells. In addition, the safety of giving these gene modified cells to humans will be tested at different cell doses. Additional objectives are to determine if this therapy can cause regression of B cell cancers and to measure if the gene modified cells survive in patients blood. Objective: To study the safety and effects of giving CD19/CD22-CAR T cells to children and young adults with B-cell cancer. Eligibility: People ages 3-39 with certain cancers that have not been cured by standard therapy. Their cancer tissue must express the CD19 protein. Design: A sample of participants blood or bone marrow will be sent to NIH and tested for leukemia. Participants will be screened with: Medical history Physical exam Urine and blood tests (including for HIV) Heart and eye tests Neurologic assessment and symptom checklist. Scans, bone marrow biopsy, and/or spinal tap Some participants will have lung tests. Participants will repeat these tests throughout the study and follow-up. Participants will have leukapheresis. Blood will be drawn from a plastic tube (IV) or needle in one arm then go through a machine that removes lymphocytes. The remaining blood will be returned to the participant s other arm. Participants will stay in the hospital about 2 weeks. There they will get: Two chemotherapy drugs by IV Their changed cells by IV Standard drugs for side effects Participants will have frequent follow-up visits for 1 year, then 5 visits for the next 4 years. Then they will answer questions and have blood tests every year for 15 years. ...
Detailed Description
Background: Acute lymphoblastic leukemia (ALL) accounts for approximately 25% of childhood cancer. Survival rates have improved, but outcomes for some subgroups, including infants and young adults remain poor, and survival for patients who relapse is < 50%, despite allogeneic stem cell transplant following second remission. CD19 immune escape has been observed by several groups following CD19-CAR therapy for B-ALL. Investigation of this phenomenon reveals a complex biology responsible for loss or downregulation of CD19 expression observed in these cases. Sequential therapy using CD22-CARs to treat CD19 dim/lo escape is associated with rapid development of resistance due to CD22 downregulation. This trial will test whether simultaneous targeting of CD19 and CD22 using a novel bivalent CD19/22-CAR is safe and feasible. Objectives: -Assess the safety of administering escalating doses of autologous CD19/CD22-CAR engineered T cells that meet established release specifications in children and young adults with CD19+CD22+ B cell ALL, isolated CNS ALL, or lymphoma following a cyclophosphamide/fludarabine conditioning regimen. Eligibility: -Participants between >= 3 years and <= 39 years of age, with CD19+/CD22+ B cell ALL, isolated CNS ALL, or lymphoma who have relapsed or have refractory disease after at least one standard chemotherapy regimen and one salvage regimen, with no alternative curative options who meet standard Phase I eligibility criteria. Design: Phase I, 3 + 3 dose escalation design using the following dose levels: -1: 1 x 10^5 transduced T cells/kg (+/- 20%); 1: 3 x 10^5 transduced T cells/kg (+/- 20%); 2: 1 x 10^6 transduced T cells/kg; and 3: 3 x 10^6 transduced T cells/kg (+/- 20%); 4: 1 x 10^7 transduced T cells/kg (+/- 20%). Participants will receive a lymphodepleting preparative regimen of fludarabine (25 mg/m^2/d x 3 on Days -4, -3, -2) and cyclophosphamide (900 mg/m^2/d x 1 on Day -2) followed by infusion of CD19/CD22-CAR T-cells on D0. Participants who are CAR pretreated (with exception for those with an interval HSCT) will receive increased lymphodepleting preparative regimen of fludarabine (30^mg/m2/d x 4 on Days -5, -4, -3, -2) and cyclophosphamide (600 mg/m2/d x 2 on Days -3, -2) followed by infusion of CD19/CD22-CAR T-cells on D0. If fludarabine is unavailable, pentostatin may be given as an alternative. Patients will be evaluated sequentially for toxicity, antitumor effects, CAR expansion and persistence, as well as research correlatives.
