Description
Inclusion Criteria:
- Informed consent.
- EBV-positive lymphoma as determined by in situ hybridization or equivalent (excluding Burkitts Lymphoma).
- Age 18 years or older.
- ECOG performance status 1, 2 or 3
- Life expectancy of at least 6 months.
- Measurable disease: either relapsing, partially responsive, refractory or progressive disease, includes disease detected either by clinical examination, radiographic evaluation (including CT scans, and at physician's discretion by functional imaging), or a persistently detectable plasma EBV viral load.
- No chemotherapy / radiotherapy and/or antibody therapy for at least 2 weeks prior to anticipated date of first infusion.
Exclusion Criteria:

- Presence of detectable malignant cells in the peripheral circulation by flow cytometry or morphology
- Serious infection within the past 28 days that has not adequately responded to therapy
- Pregnancy, or unwilling to use adequate contraception
- Serology (taken within 3 months of CTL release date) indicating active HBV or HCV infection, positive serology for HIV I&II, HTLV1 or syphilis
- Negative serology for EBV
- Psychiatric, addictive or any condition which may compromise the ability to participate in this trial

|
Experimental: Single group study
Autologous AdE1- Latent Membrane Protein (LMP) Cytotoxic T Lymphocytes.

Total dose 20-800 million CTL given in 4 equal doses (5-200 million CTL) given intravenously, at weekly intervals for the first cohort of 10 patients and twice a week for the second cohort of 10 patients.

Outcome Measure |
Time Frame |
|---|---|
|
Feasibility (generation of autologous clinical grade AdE1-LMP-specific CTL from the blood of EBV-positive lymphoma patients)
Time Frame: The investigational product for each participant will be assessed post production. The patient will have blood samples taken prior to and following each infusion, and then at 1, 3, 6 & 12 months following the final infusion.

|
|
Safety as assessed by adverse event monitoring. Patients will be questioned and toxicities recorded according to the International Common Toxicity Criteria.
Time Frame: 1 hour post 4 AdE1-LMP CTL injections (injections are weekly for first 10 participants & twice weekly for the next 10 participants), 3-5 weeks post the 4th injection, then 3, 6 and 12 months post the 4th injection

1 hour post 4 AdE1-LMP CTL injections (injections are weekly for first 10 participants & twice weekly for the next 10 participants), 3-5 weeks post the 4th injection, then 3, 6 and 12 months post the 4th injection
|
|
Reconstitution of EBV-specific CTL immunity with anti-viral efficacy measured by immunological & virological assessment of blood samples including immunophenotyping, intracellular cytokine assays, CD107 cytotoxicity assays and EBV DNA load analysis.
Time Frame: At baseline, pre and 1 hour post 4 AdE1-LMP CTL injections, 3-5 weeks post the 4th injection, then 3, 6 and 12 months post the 4th injection

Secondary Outcome Measures
Secondary Outcome Measures
Outcome Measure |
Time Frame |
|---|---|
|
Optimal dose intensity of the intervention. Clinical efficacy (radiological assessment by CT), biological efficacy (reconstitution of EBV-specific CTL immunity & anti-viral efficacy), safety & efficacy of the 1st treatment schedule vs the 2nd schedule
Time Frame: Clinical evaluation, AE monitoring & collection of blood samples at baseline, pre & 1 hr post injections, 3-5 weeks, 3, 6 and 12 months post 4th injection. Radiological examination at baseline & at 3 to 5 wks & 3 months post the 4th treatment.
