Brief Summary
The aim of this clinical trial is to evaluate the feasibility, safety and biological effect of adoptive transfer of CD19ζ chimaeric receptor transduced donor-derived EBV-specific cytotoxic T-lymphocytes (EBV-CTL) in patients with high-risk or relapsed B cell precursor ALL after allogeneic Haematopoietic Stem Cell Transplantation (HSCT).

Outcome Measures
Primary Outcomes (2)
Toxicity attributable to transfer of CD19-zeta transduced CTL
1. Incidence of grade 3-5 toxicity attributable to transfer of CD19-zeta transduced CTL within 12 weeks of infusion. 2. Incidence of significant (Grade II-IV) and severe (Grade III-IV) acute GVHD before day 100 and limited/extensive chronic GVHD between day 100-365. 3. Incidence of hypogammaglobulinaemia after CD19-zeta CTL transfer at day 100, 6 months and 1 year post-HSCT
1 year
Biological efficacy as assessed by effect of CD19-zeta transduced CTL on Minimal Residual Disease levels in the bone marrow in the first year post- transduced CTL infusion
1 year
Secondary Outcomes (3)
Persistence and frequency of circulating CD19-zeta transduced CTL in the peripheral blood of recipients after adoptive transfer as assessed by flow cytometry and quantitative real-time PCR.
1 year
In vitro anti-leukaemic response of circulating PBMC post adoptive transfer of CD19-zeta transduced CTL using interferon-gamma ELISPOT assays after stimulation with CD19+ve targets
1 year
Relapse rate, disease-free survival and overall survival at 1 and 2 years after adoptive immunotherapy with CD19ζ-transduced EBV-CTL
2 years
Study Arms (2)
Prophylaxis arm
EXPERIMENTALPatients who have relapsed in the bone marrow after previous myeloablative HSCT and achieve remission after chemotherapy will be treated prophylactically with CD19-specific gene-engineered T cells after a second HSCT with reduced intensity conditioning.
Pre-emptive arm
EXPERIMENTALIn this arm, patients identified at high (\> 50%) risk of relapse will be eligible for generation of donor-derived EBV CTL immediately prior to HSCT. These patients will be monitored for evidence of MRD in regular bone marrow aspirates for the first year post-HSCT. MRD positivity post-HSCT is highly predictive of subsequent relapse. In those patients who become MRD+ in the marrow at a level of minimum 5 x 10-4, cryopreserved CTL that have been transduced with a retroviral vector carrying the CD19-zeta transgene will be thawed and administered to the patient pre-emptively.
Interventions
All patients will be treated at the same total dose level of 2 x 10\^8/m2
The initial cohort of 5 patients (regardless of arm of study) will be treated as described. If transduced CTL infusion is safe in this initial cohort and real-time DNA PCR studies demonstrate that transduced CTL are undetectable in \> 50% of patients by 2 months post-infusion, the remaining 25 patients (in either arm of the study) will be treated as above but with an additional vaccination of CD19-zeta-transduced EBV-LCL infusion. Vaccination will consist of 3 doses of 5 x 10\^6 irradiated (70Gy) donor-derived EBV-lymphoblastoid cell line used to generate CTL and will be administered subcutaneously into the thigh (volume 0.3 ml) at day -2, week 4 and 8 post-transduced CTL infusion.
Eligibility Criteria
You may qualify if:
- Children (18 years or younger) with CD19+ precursor B cell ALL fulfilling one of the following criteria who are undergoing an allogeneic stem cell transplant from an EBV-seropositive donor:
- In first remission, if at least one of the following criteria are met:
- t(9;22) and MRD positive (BCR-ABL/ABL ratio \> 0.01%) after HR3 block of EsPhALL or pre-HSCT or
- Infant ALL age \< 6 months at diagnosis with MLL gene rearrangement and either presenting wcc \>300 x 10\^9/L or poor steroid early response (i.e circulating blast count \>1x10\^9/L following 7 day steroid pre-phase of Interfant 06) or
- Resistant disease (\> 30% blasts at end of induction treatment day 28-33) in subsequent morphological CR or
- High level bone marrow MRD (\> 1 in 1000) at week 12 ALL-BFM 2000/AIEOP BFM ALL 2009/EORTC 58951 protocols, week 12-15 of FRALLE A or at week 14 of UKALL2011
- Relapsed patients if at least one of the following criteria are met:
- Very early (\< 18 months from diagnosis) bone marrow or extramedullary relapse in second CR or
- Early (within 6 months of finishing therapy) isolated bone marrow relapse with bone marrow MRD \> 1 in 100 at day 35 of reinduction in second CR or
- Early (within 6 months of finishing therapy) bone marrow or combined relapse with high level bone marrow MRD (\> 1 in 1000) at the end of consolidation therapy (week 12-13 UKALL R3/INTREALL and COOPRALL protocols, prior to protocol M in BFM relapse protocol (ALL-REZ BFM 2002) and after Protocol II-IDA in AIEOP LLA Rec 2003)or
- Any relapse of infant or Philadelphia-positive ALL in morphological complete remission
- Any patient being transplanted in 3rd or greater CR
- These patients have a high (\> 50%) risk of relapse and will be monitored for evidence of MRD in bone marrow aspirates (monthly for months 1-6, 6 weekly months 7.5-12 post HSCT) for the first year post-transplant. Patients who become MRD +ve in the marrow at a level minimum 5 x 10-4 (or BCR-ABL/ABL ratio 0.05% in Ph+ve ALL patients with no IgH MRD marker) but are in morphological remission (\<5% blasts in BM) will be eligible to be treated pre-emptively with CD19ζ transduced CTL
- Prophylaxis arm
- Additionally, any patient (≤ 18 years) with ALL relapsing in the bone marrow (isolated or combined) after myeloablative allogeneic HSCT who achieves morphological remission after re-induction and who is a candidate for second HSCT at one of the participating centres is eligible to receive CD19ζ transduced CTL prophylactically
- +5 more criteria
You may not qualify if:
- Patients with CD19 negative precursor B cell ALL
- EBV seronegative or \> single antigenic/allelic HLA-mismatched donor
- Active acute GVHD overall Grade 2 or higher or significant chronic GVHD requiring systemic steroids at the time of scheduled infusion of transduced CTL will be excluded until the patient is GVHD-free and off steroids
- Pre-existing severe lung disease (FEV1 or FVC \< 50% predicted) pre-HSCT or an oxygen requirement of \>28% O2 supplementation or active pulmonary infiltrates on chest X-ray at the time scheduled for transduced CTL infusion
- Serum bilirubin \>3 times the upper limit of normal or an AST or ALT \> 5 times the upper limit of normal
- Serum creatinine \>3 times upper limit of normal
- Active severe intercurrent infection at the time of transduced CTL infusion (if present consult with Chief investigator).
- Patients in whom transduced donor-derived EBV-specific CTLs don't meet release criteria
- Serologically positive for Hepatitis B, C or HIV pre-HSCT
- Females of childbearing age with a positive pregnancy test
- Known allergy to DMSO
