This study is currently recruiting participants.
Acute lymphoblastic leukemia (ALL) is the most common cancer in children. About 90% of children and young adults who are treated for ALL can now be cured. But if the disease comes back, the survival rate drops to less than 50%. Better treatments are needed for ALL relapses.
To test chimeric antigen receptor (CAR) therapy. CARs are genetically modified cells created from each patient s own blood cells. his trial will use a new type of CAR T-cell that is targeting both CD19 and CD22 at the same time. CD19 and CD22 are proteins found on the surface of most types of ALL.
People aged 3 to 39 with ALL or related B-cell lymphoma that has not been cured by standard therapy.
Participants will be screened. This will include:
Lumbar puncture. A needle will be inserted into the lower back to draw fluid from the area around the spinal cord.
Participants will undergo apheresis. Their blood will circulate through a machine that separates blood into different parts. The portion containing T cells will be collected; the remaining cells and fluids will be returned to the body. The T cells will be changed in a laboratory to make them better at fighting cancer cells.
Participants will receive chemotherapy starting 4 or 5 days before the CAR treatment.
Participants will be admitted to the hospital. Their own modified T cells will be returned to their body.
Participants will visit the clinic 2 times a week for 28 days after treatment. Follow-up will continue for 15 years.

--- Age (Years) 6 to <= 10 / Maximum Serum Creatinine (mg/dL) <= 1.0
--- Age (Years) >10 / Maximum Serum Creatinine (mg/dL) <= 1.2
*a participant will not be excluded because of pancytopenia >= Grade 3 if it is due to underlying bone marrow involvement by leukemia
- Central nervous system (CNS) Status
- Participants with leukemia with CNS 1 and 2 disease are eligible in the absence of exclusion criteria
- Participants of child-bearing or child-fathering potential must be willing to practice effective birth control from the time of enrollment until 12 months following completion of study treatment for women and for 4 months following completion of study treatment for men.
- Participants who are breastfeeding or plan to breastfeed must agree to discontinue/postpone breastfeeding while on study therapy and until 1 month after the administration of CAR.
- Cardiac function: Left ventricular ejection fraction >= 45% or fractional shortening >=28%
- Pulmonary Function
-- Baseline oxygen saturation >92% on room air at rest
- Ability of participant or Legally Authorized Representative (LAR) to understand and the willingness to sign a written informed consent document.
- Ability and willingness of participant or Legally Authorized Representative (LAR) to co- enroll on 15-C-0028: Follow-up Evaluation for Gene-Therapy Related Delayed Adverse Events after Participation in Pediatric Oncology Branch Clinical Trials.
EXCLUSION CRITERIA:
Participants meeting any of the following criteria are not eligible for participation in the study:
- Participants with CNS3 disease, progressing neurologic signs* of CNS disease, radiologically detected active CNS lymphoma (*resolving manifestation or persistent and/or irreversible findings from prior CNS involvement (e.g., blindness) is not exclusionary)
- Hyperleukocytosis (>= 50,000 blasts/microL)
- Positive serum or urine beta-HCG pregnancy test performed at screening.
- Participants will be excluded based on prior therapy if they fail to meet following washout criteria:
-- Therapy: Systemic Chemotherapy, anti-neoplastic agents, antibody- based therapies
-- Washout*: >=2 weeks
-- Exceptions: 6 weeks for clofarabine or nitrosoureas; No washout for prior intrathecal chemotherapy, steroid therapy, hydroxyurea (no dose increases within prior 2 weeks) or ALL maintenance-type chemotherapy (vincristine, 6-mercaptopurine, oral methotrexate, or a tyrosine kinase inhibitor for participants with Ph+ ALL) provided there is recovery from any acute toxic effects
-- Therapy: Radiation
-- Washout*: >=3 weeks
-- Exceptions: No time restriction with radiation therapy if the volume of bone marrow treated is less than 10% and the participant has measurable/evaluable disease outside the radiation window
-- Therapy: Allogeneic Stem Cell Transplant
-- Washout*: >= 100 days since SCT; >= 30 days since completion of immunosuppression; >= 6 weeks since donor lymphocyte infusion (DLI)
-- Exceptions: Cannot have evidence of active graft-versus-host disease (GVHD)
