Primary Outcome Measures:
  • To determine safety and to characterise the toxicity profile of MVA-EBNA1/LMP2 vaccine [ Time Frame: 4 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To describe changes in the frequency of functional T-cell responses to MHC class I and II-restricted epitopes within EBNA1 and LMP2 in peripheral blood at sequential time-points before, during and up to nine months after the vaccination course. [ Time Frame: 4 years ] [ Designated as safety issue: No ]
  • To assess changes in levels of EBV genome levels in plasma [ Time Frame: 4 Years ] [ Designated as safety issue: No ]

Enrollment: 18
Study Start Date: September 2006
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MVA Vaccine Drug: 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.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

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
