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.

Condition or disease Intervention/treatment Phase
Acute Lymphoid Leukemia B-Cell Leukemia Leukemia, Lymphocytic, B Cell B-Cell Lymphoma Lymphoma, Non-Hodgkin Biological: CD19/CD22 CAR T-Cells Drug: Fludarabine Drug: Cyclophosphamide Phase 1

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.

Criteria
  • 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. For those being considered for reinfusions, measurable or evaluable disease is not required at the time of reinfusion..
  • 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.

EXCLUSION CRITERIA:

Subjects meeting any of the following criteria are not eligible for participation in the study:

  • Recurrent or refractory ALL limited to isolated testicular or isolated central nervous system (CNS) disease.
  • Subjects with radiologically detected active CNS lymphoma or isolated CNS disease which are eligible for definitive CNS directed radiation therapy will be excluded.
  • Hyperleukocytosis (greater than or equal to 50,000 blasts/micro L) or rapidly progressive disease that in the estimation of the investigator and sponsor would compromise ability to complete study therapy;
  • Pregnant women are excluded from this study because the study agents have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study agents, breastfeeding should be discontinued.
  • Subjects will be excluded related to the following prior therapy criteria:

    • Systemic chemotherapy, anti-neoplastic investigational agents, or antibody based therapies =<2 weeks (6 weeks for clofarabine or nitrosoureas) prior to apheresis with the following exception:

      ---No time restricution with prior intrathecal chemotherapy, steroid therapy, hydroxyurea or ALL maintenance type chemotherapy (vincristine, 6-mercaptopurine, oral methotrexate, or a tyrosine kinase inhibitor for patients with Ph+ ALL) provided there is recovery from any acute toxic effects.

    • Radiation therapy =<3 weeks prior to apheresis with the following exception:

      ---No time restriction with radiation therapy if the volume of bone marrow treated is less than 10% and the subject has measureable/evaluable disease outside the radiation window.

  • HIV/HBV/HCV Infection:

    • a. Seropositive for HIV antibody. (Patients with HIV are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy in the future should study results indicate effectiveness.)
    • 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;
  • History of severe, immediate hypersensitivity reaction attributed to compounds of similar chemical or biologic composition to any agents used in study or in the manufacturing of the cells.
