Brief Summary

RATIONALE: Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of vaccine therapy in treating patients with Epstein-Barr virus and cancer.

Detailed Description

OBJECTIVES:

Primary

• To determine safety and to characterize the toxicity profile of EBNA1 C-terminal/LMP2 chimeric protein-expressing recombinant modified vaccinia Ankara vaccine in patients in remission having been treated conventionally for Epstein-Barr virus (EBV) and malignancy.
• To describe changes in the frequency of functional T-cell responses to major histocompatibility complex (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 in these patients.

Secondary

• To assess changes in levels of EBV genome in plasma in these patients.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive EBNA1 C-terminal/LMP2 chimeric protein-expressing recombinant modified vaccinia Ankara vaccine intradermally on day 1. Treatment repeats every 3 weeks for 3 courses in the absence of disease progression or unacceptable toxicity.

Blood samples are collected periodically for immune function, biomarker, and pharmacological studies.

After completion of study treatment, patients are followed up at weeks 11 and 14, and at 6 months and 1 year.

Eligibility Criteria

Inclusion Criteria

DISEASE CHARACTERISTICS:

• Histologically confirmed malignancy of a type typically associated with Epstein-Barr virus (EBV) latent infection meeting the following criteria:

• The presence of EBV within the malignant cells has been demonstrated by immunohistochemistry for viral antigens or by EBER (EBV early RNA) in situ hybridization
• Patients in remission from disease or with disease for which no standard treatment is appropriate, as defined by 1 of the following groups:

• Have achieved a continuing complete response (CR) or unconfirmed CR
• Residual masses at the site of treated disease that are not progressing (i.e., stable disease) and for which no standard therapy is recognized
• Residual or recurrent disease that is low-volume and causing minimal or no symptoms and for which no standard therapy is recognized
• Completed standard therapy for malignancy ≥ 12 weeks before trial entry

• No more than 1 course of chemotherapy as treatment for EBV+ malignancy
• No ongoing toxic manifestations of prior treatment, except alopecia or certain grade 1 toxicities at the discretion of the investigator and Cancer Research UK
• No patients with active EBV+ cancer for whom evidence-based active treatment is available and likely to be offered to prolong life or relieve symptoms within 14 weeks of the first vaccination

PATIENT CHARACTERISTICS:

• WHO performance status 0 or 1
• Life expectancy ≥ 4 months
• Lymphocyte count must satisfy 1 of the following criteria:

• Greater than lower limit of the reference range in the investigator site
• Greater than or equal to 0.5 x 10^9/L AND recovery from nadir of lymphocyte numbers following primary treatment for EBV+ malignancy, judged by no successive rises in lymphocyte count measured up to 3 successive occasions 3 weeks apart
• Hemoglobin > 10.0 g/dL
• Absolute neutrophil count ≥ 1.5 x 10^9/L
• Platelet count ≥ 100 x 10^9/L
• Serum bilirubin ≤ 1.5 times upper limit of normal (ULN)
• Serum alkaline phosphatase < 1.5 times ULN
• ALT and/or AST < 1.5 times ULN
• Calculated creatinine clearance > 50 mL/min (uncorrected value) OR isotope clearance measurement > 50 mL/min
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception during study and for 6 months after completion of study treatment
• No known chronic active infection with hepatitis B, hepatitis C, or HIV
• No history of anaphylaxis or severe allergy to vaccinations
• No allergy to eggs or egg products
• No ongoing active infection
• No known splenic dysfunction
• No concurrent active autoimmune disease
• No prior NYHA class III or IV cardiac disease or concurrent congestive heart failure
• No concurrent active skin diseases requiring therapy (i.e., psoriasis, eczema)
• No other condition that, in the Investigator's opinion, would make the patient not a good candidate for this clinical trial

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics
• No prior myeloablative therapy followed by an autologous or allogeneic hematopoietic stem cell transplant
• More than 12 weeks since prior and no concurrent chemotherapy or radiotherapy
• No splenectomy or splenic irradiation
• No concurrent immunosuppressive medication, including corticosteroids

• Long-term prophylactic use of inhaled corticosteroids allowed
• No major thoracic and/or abdominal surgery within the past 4 weeks from which the patient has not yet recovered
• No other concurrent anticancer or investigational drugs

• Minimum Eligible Age: 18 Years
