Beskrivelse
Inclusion Criteria:
- Histologically confirmed NPC, in which the presence of EBV within the malignant cells has been demonstrated by (1) EBER (EBV early RNA) in situ hybridisation in more than 50% of the malignant cells, or (2) undifferentiated or poorly differentiated carcinoma histology in association with a raised serum titer of IgA to EBV VCA.
- Patients in remission from disease, ie complete response (CR) or unconfirmed complete response (CRu).
- Completion of standard therapy for malignancy at least 12 weeks before trial entry.
- Written informed consent and the ability of the patient to co-operate with treatment and follow up must be ensured and documented.
- Age greater than 18 years.
- World Health Organisation (WHO) performance status of 0 or 1
- Life expectancy of at least 4 months.
Haematological and biochemical indices (these measurements must be performed within 28 days prior to the patient going on study):
- Haemoglobin (Hb) > 10.0 g/dl
- Lymphocytes > 1.0 x 109/L (or above the lower limit of normal range of institutional laboratory)
- Neutrophils ≥ 1.5 x 109/L
- Platelets (Plts) ≥ 100 x 109/L
- baseline liver function tests :
- Serum bilirubin ≤ 1.5 x upper normal limit
- Serum alkaline phosphatase, alanine amino-transferase (ALT) and/or aspartate amino-transferase (AST) < 1.5 x ULN.
- baseline renal function test:
- calculated creatinine clearance > 50ml/min Female patients of child-bearing potential are eligible, provided they have a negative pregnancy test prior to enrolment and agree to use appropriate medically approved contraception during the study up to six months after the last vaccination.
- Male patients must agree to use appropriate medically approved contraception during the study up to six months after the last vaccination.
Exclusion Criteria:
- Receiving current chemotherapy or radiotherapy, or received within 12 weeks of trial entry.
- Known chronic active infection with Hepatitis B, Hepatitis C or Human Immunodeficiency Virus (HIV).
- Current active autoimmune disease.
- Current active skin diseases requiring therapy (psoriasis, eczema etc).
- Ongoing active infection.
- History of anaphylaxis or severe allergy to vaccination.
- Allergy to eggs or egg products.
- Previous myeloablative therapy followed by an autologous or allogeneic haematopoietic stem cell transplant.
- Patients who have had a splenectomy or splenic irradiation, or with known splenic dysfunction.
- Receiving current immunosuppressive medication, including corticosteroids.
- Pregnant and lactating women.
- Ongoing toxic manifestations of previous treatment. Exceptions to this are alopecia or certain Grade 1 toxicities which in the opinion of the Investigator and Cancer Research UK should not exclude the patient.
- Major thoracic and/or abdominal surgery in the preceding four weeks from which the patient has not yet recovered.
- Patients with any other condition which in the Investigator's opinion would not make the patient a good candidate for the clinical trial.
- Concurrent congestive heart failure or prior history of class III/ IV cardiac disease

Eksperimentel: MVA Vaccine
|
The starting dose will be 5 x 107 plaque forming units (pfu) given by intradermal vaccination.
Cohorts of three patients will receive escalating doses of the vaccine (100%, 100%, 67% and 50%).
The dose escalation scheme is 5 x 107 pfu, 1 x 108 pfu, 2 x 108 pfu, 3.3 x 108 pfu, 5 x 108pfu.
This will be dependant on toxicity.
