Brief Summary
The overall objective of this protocol is to improve the cure rate of relapsed precursor B-cell acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma. This phase II trial is studying risk-directed therapy for B-lymphoblastic leukemia or lymphoma in first relapse. Standard risk (SR) and high risk (HR) participants will receive different therapy. Treatment will consist of chemotherapy for SR participants, and chemotherapy followed by hematopoietic stem cell transplant (HSCT) for HR in first relapse. Induction therapy consists of three blocks of chemotherapy. The first block is a novel immunotherapy regimen that includes chemotherapy, rituximab and infusion of haploidentical natural killer (NK) cells. SR participants will continue to receive chemotherapy for a total duration of approximately 2 years. HR participants will be candidates for HSCT and will proceed to transplant once a suitable donor is found and their minimal residual disease (MRD) is negative.

The mechanism of action of the CliniMACS Cell Selection System is based on magnetic-activated cell sorting (MACS). The CliniMACS device is a powerful tool for the isolation of many cell types from heterogeneous cell mixtures, (e.g. apheresis products). These can then be separated in a magnetic field using an immunomagnetic label specific for the cell type of interest, such as CD3+ human T cells.
Eligibility Criteria
You may qualify if:
- Must have relapsed or refractory precursor B-cell acute lymphoblastic leukemia or acute lymphoblastic lymphoma.
- Participants with leukemia must meet one of the following:
- In first hematologic relapse, defined as the reappearance (in a patient who has previously achieved remission) of leukemia blasts in the bone marrow or peripheral blood, OR
- Refractory to one or two courses of frontline induction therapy (≥ 5% blasts in the bone marrow or peripheral blood confirmed by flow cytometric analysis).
- Participant with lymphoma must meet one of the following:
- In first relapse, OR
- Refractory to one or two courses of frontline induction therapy with measurable disease
- Should flow cytometric analyses suggest relapse (by the reappearance of a similar immunophenotype to the original leukemia) in the presence of \<5% blasts morphologically, a repeat bone marrow test is recommended to confirm relapse.
- Molecular or genetic relapse is characterized by the reappearance of a cytogenetic or molecular abnormality.
- Early relapse is defined as relapse on therapy or \< 6 months after completion of frontline therapy. Late relapse is defined as relapse occurring ≥ 6 months after completion of frontline therapy.
- Participant's age is \< 22 years at time of enrollment (e.g. participant is eligible until 22nd birthday).
- Prior therapy:
- There is no waiting period for participants who relapse while receiving frontline therapy and are free from side effects attributable to such therapy.
- Emergent radiation therapy, one dose of intrathecal chemotherapy, and up to 7 days of steroids for treatment of relapse are permitted before start of treatment in participants who relapse after completion of frontline therapy.
- At least 90 days have elapsed since bone marrow transplant and participant is off immune suppression for a minimum of 2 weeks, if applicable. Participants with ALL or NHL who were transplanted in first remission are eligible for this study.
- +10 more criteria
You may not qualify if:
- Leukemia participants ages 1 to 5 years with induction failure AND favorable cytogenetics (i.e., hyperdiploidy defined as DNA index ≥1.16 or modal chromosome number ≥51, or ETV6-RUNXI).
- Hepatitis B or HIV infection.
- Pregnant or breast-feeding
- Inability or unwillingness or research participant or legal guardian/representative to give written informed consent.
- Donor is at least 18 years of age.
- Donor is a family member.
