| Scientific title | Epstein-barr virus (EBV)-specific immune effector cell (EBV-IE) for pre-emptive/preventive and therapeutic treatment of EBV-related diseases such as lymphoproliferative disorder (LPD) and post-transplantation lymphoproliferative disorder (PTLD) |
| Study objectives | Epstein-barr virus (EBV) is a common human pathogen. In healthy individuals, EBV infection is often self-resolved. However, in immune compromised individuals such as transplant patients, or young and elderly individuals, EBV-related diseases can be lethal. The development of an effective immune response is the best solution to treating EBV diseases. We hypothesise that EBV-specific immune effector cells can be used to prevent or cure EBV-associated disorders including lymphomas. Such immune effector cells can come from the patient's own blood, or human leukocyte antigen (HLA)-matched donors' blood. EBV-specific immune effector (IE) cells will be generated in ex-vivo culture and infused into patients. The safety of this approach, and virus titre and EBV-associated diseases will be closely monitored. The study will determine if EBV-specific IE cells can be used to prevent EBV infections and treat EBV-related diseases. |
| Ethics approval(s) | The 144th meeting of Research Ethics Committee of the National Taiwan University Hospital approved on the 14th November 2008 (ref: 200809044D); approved duration: 05/12/2008 - 04/12/2009 |
| Health condition(s) or problem(s) studied | EBV-related diseases |
| Intervention | The pre-emptive/preventive arm of treatment is a phase I/II trial, non-blind, single site, single group (compared with historical database) study, and the subjects will be followed up for one year after treatment. Each subject will receive four infusions of EBV-specific immune effector cells, with seven follow-ups: one week after the last infusion, one month thereafter for three months, and every three months thereafter until the end of the trial. The data collected in this trial will be compared with historical data. |

| Phase | Phase I/II |
| Drug / device / biological / vaccine name(s) | EBV-specific immune effector cells |
| Primary outcome measure | Patients' immediate clinical response after IE cell infusion, e.g., body temperature and symptoms related to GvHD. In addition, virus titre or DNA copy in blood or tissue biopsy will be monitored. Outcomes are measured at 24 hours, day 2, day 3, day 4, day 5, day 6, day 7, week 2, week 4, month 2, month 3, month 6 and year 1. |
| Secondary outcome measures | To evaluate the rate of successful EBV-IE generation and ability of EBV-IE for anti-EBV efficacy and EBV reactivation prophylaxis: 1. Production: IE cell preparation success rate - the minimal IE cell number can be generated per subject 2. Efficacy: 2.1. Tracking EBV titre or copy number 2.2. EBV IE cell function analysis in vitro and its correlation with in vivo effect 2.3. Effect on PTLD - for subjects with EBV-PTLD 2.4. Effect on mononucleosis - body temperature and EBV titer will be monitored 2.5. Survival rate and the time required to recover completely from EBV-related diseases (LPD, PTLD) 3. Prevention: determine the time and frequency of EBV-related disease incidence in subjects after the first IE cell infusion, in comparison to historically-documented uninfused subjects 4. Safety: 4.1. Adverse effect documentation 4.2. National Cancer Institute Common Toxicity Criteria (NCI-CTC) grade 3 or above response 4.3. Changes in biochemical parameters: 4.3.1. Complete blood count (CBC) 4.3.2. SGPT (aspartate aminotransferase [AST]), SGOT (alanine aminotransferase [ALT]), total bilirubin, gamma glutamyl transferase (g-GT) 4.3.3. Creatinine, blood urea nitrogen (BUN), uric acid 4.4. Physical response 4.5. Life sign changes: 4.5.1. Blood pressure 4.5.2. Pulse 4.5.3. Temperature Outcomes are measured at 24 hours, day 2, day 3, day 4, day 5, day 6, day 7, week 2, week 4, month 2, month 3, month 6 and year 1. |
