Modified Vaccinia Ankara (MVA) Vaccine Study

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).

• 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.

• 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.

• 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
