Brief Summary:
This is a phase 1, interventional, open label, treatment study designed to evaluate the safety and feasibility of infusion of CAR-20/19-T in pediatric and young adult subjects with B cell ALL that have relapsed after prior therapies or refractory disease and are not candidates for curative intent standard therapy. There will be two phases of this study. A dose escalation phase to determine the safe CAR-20/19-T cell dose in patients B-cell ALL. Once the desired dose has been identified there will be a 6-patient dose expansion phase at the specified dose level.

Arm Intervention/treatment
Experimental: Dose Escalation Phase Biological: CAR-20/19-T cells

The investigational agent in this protocol is the CAR-20/19-T cells.CAR-20/19-T cells will be administered either fresh or thawed after cryopreservation by IV injection. Patients will receive one of four dose levels of CAR-20/19-T cells based on our dose escalation design (Section 6). Cell dose will be maxed at 80 kg.

Dose Level -1: 1 x 10*5 CAR-20/19-T cells/kg Dose Level 0: 2.5 x10*5 CAR-20/19-T cells/kg (starting dose level) Dose Level 1: 7.5 x10*5 CAR-20/19-T cells/kg Dose Level 2: 2.5 x10*6 CAR-20/19-T cells/kg (goal cell dose)


Experimental: Dose Expansion Phase Biological: CAR-20/19-T cells

The investigational agent in this protocol is the CAR-20/19-T cells.CAR-20/19-T cells will be administered either fresh or thawed after cryopreservation by IV injection. Patients will receive one of four dose levels of CAR-20/19-T cells based on our dose escalation design (Section 6). Cell dose will be maxed at 80 kg.

Dose Level -1: 1 x 10*5 CAR-20/19-T cells/kg Dose Level 0: 2.5 x10*5 CAR-20/19-T cells/kg (starting dose level) Dose Level 1: 7.5 x10*5 CAR-20/19-T cells/kg Dose Level 2: 2.5 x10*6 CAR-20/19-T cells/kg (goal cell dose)





Primary Outcome Measures :
  1. Determine the safety (dose level) of CAR-20/19-T cell administration in relapsed refractory B-ALL. [ Time Frame: 40 months ]
    Safety will be determined by assessments of CRS using the Lee et al. grading scale [1] and adverse events via NCI CTCAE version 5.0. Response assessment occur initially at Day +28 post-treatment (+/- 3 days) with CAR-20/19-T cells. Ongoing response assessment will continue until progression and/or death up to 2 years (see Table 1), after which patients will be transitioned to a long-term follow-up protocol.

  2. Determine the feasibility to manufacture CAR-20/19-T cells locally from pediatric and young adult apheresis products using the CliniMACS Prodigy Cell processing device. [ Time Frame: 40 months ]
    Feasibility of CAR-20/19-T cell production by the CliniMACS Prodigy processing device (Miltenyi Biotec) will be measured. At minimum, we expect to reach our target CAR-20/19-T cell dose in at least 75% of subjects with an adequate T cell starting dose. Feasibility will be measured at the end of the study after completion of accrual. If >25% of subjects with an adequate T cell starting dose were unable to achieve goal CAR-20/19-T cell dose, we would deem that this technique is not a feasible method for production.


Secondary Outcome Measures :
  1. Determine the anti-tumor responses as measured by response rates. [ Time Frame: 40 months ]
  2. Describe the duration of response for responding patients. [ Time Frame: 40 months ]
  3. Determine persistence of CAR-20/19-T cells. [ Time Frame: 40 months ]
  4. Determine the effects of CAR-20/19-T infusion on non-neoplastic CD19 & CD20 B cells in vivo. [ Time Frame: 40 months ]
  5. Evaluate MRD using molecular technologies. [ Time Frame: 40 months ]
