Clinical Benefit Rate [ Time Frame: 2 Years ]
Clinical benefit rate (CBR, percent of patients experiencing complete response [CR], partial response [PR] or stable disease [SD] for at least 12 weeks from post cycle 2 to cycle 6 measurements) determined according to the Response Evaluation Criteria in Solid Tumours (RECIST), or by immune-related Response criteria (irRC) in the absence of measurable disease.
Clinical Benefit Rate [ Time Frame: 2 Years ]
Clinical benefit rate (CBR, percent of patients experiencing CR, PR or SD for at least 12 weeks from post cycle 2 to cycle 6 measurements) determined according to the Response Evaluation Criteria in Solid Tumours (RECIST), or on EBV genome levels in the absence of measurable disease.

  • Objective Response Rate (ORR) [ Time Frame: 2 Years ]
    ORR is defined as the proportion of patients with confirmed complete response (CR) or confirmed partial response (PR) from post cycle 2 to cycle 6 measurements according to the Response Evaluation Criteria in Solid Tumours (RECIST), relative to the total evaluable patient population.
  • Duration of Response (DR) [ Time Frame: 2 Years ]
    DR is defined as the time from the first documentation of objective tumour response to the first documentation of objective tumour progression or to death due to any cause.
  • Progression-free survival (PFS) [ Time Frame: 3 Years ]
    PFS is defined as the time from post cycle 2 measurement to first documentation of objective tumour progression, or to death due to any cause.
  • Overall survival (OS) [ Time Frame: 3 Years ]
    Overall survival (OS) is defined as the time from start of study treatment to date of death due to any cause.
  • Objective Response Rate (ORR) [ Time Frame: 2 Years ]
    ORR is defined as the proportion of patients with confirmed complete response (CR) or confirmed partial response (PR) from post cycle 2 to cycle 6 measurements according to the Response Evaluation Criteria in Solid Tumours (RECIST, see appendix 3), relative to the total evaluable patient population.
  • Duration of Response (DR) [ Time Frame: 2 Years ]
    DR is defined as the time from the first documentation of objective tumour response to the first documentation of objective tumour progression or to death due to any cause.
  • Progression-free survival (PFS) [ Time Frame: 3 Years ]
    PFS is defined as the time from post cycle 2 measurement to first documentation of objective tumour progression, or to death due to any cause.
  • Overall survival (OS) [ Time Frame: 3 Years ]
    Overall survival (OS) is defined as the time from start of study treatment to date of death due to any cause.

Inclusion Criteria:

  • Histologically confirmed diagnosis of nasopharyngeal carcinoma (NPC) (either at initial diagnosis or at recurrence).
  • NPC associated with EBV infection, determined as:

    • NPC occurred in association with a raised serum titre of IgA to EBV viral capsid antigen (VCA) in a patient living in an area of high incidence of EBV+ undifferentiated NPC, or
    • The presence of EBV has been confirmed in the tumour by immunohistochemistry for EBV antigens or in situ hybridization for EBV early RNA (EBER), or
    • NPC with persistent or recurrent disease occurs in the context of an elevated circulating EBV genome level
  • Patients with persistent, recurrent or metastatic NPC that have residual EBV DNA following completion of conventional therapy (chemotherapy or radiotherapy).

    • Patients with residual masses at the site(s) of previous disease that are not progressing and for whom no standard therapy is currently appropriate.
    • Patients with residual or recurrent disease that is low volume, that is causing minimal or no symptoms and for whom no standard therapy is currently appropriate.
  • Disease must be not amenable to potentially curative radiotherapy or surgery.
  • Completion of standard therapy for malignancy at least 4 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.
  • 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:

  • Chemotherapy, radiotherapy, or major surgery received within 4 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 (inhaled steroids are acceptable).
  • 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 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.
