Summary
This research study is studying a therapeutic vaccine, named DPX-E7, as a possible treatment for Human Papilloma Virus or HPV related head and neck, cervical or anal cancer (positive for HLA-A*02).
Eligibility Criteria
Inclusion Criteria
- Each patient must be positive for HLA-A*02 and meet all of the following inclusion criteria to be enrolled in the study:
- Histologically or cytologically proven HPVOC or cervical cancer or anal cancer, based on expression of HPV type16 in immunohistochemistry and/or HPV 16 DNA analysis by ISH of tumor tissue from the primary or metastatic lesions.
- Incurable HPVOC, as defined by:
- Relapsed or progressive disease at the primary site and/or regional lymph nodes after initial treatment (e.g. Surgery, radiotherapy or chemoradiotherapy) with no potentially curative option (i.e. surgery or radiation); OR
- Distant metastasis
- Incurable cervical or anal cancer, as defined by:
- Relapsed or progressive disease at the primary site and/or regional lymph nodes after initial treatment (e.g. systemic chemotherapy) with no potentially curative option (i.e. surgery or chemoradiotherapy). Chemotherapy administered in conjunction with primary radiation as a radiosensitizer will not be counted as a systemic chemotherapy regimen; OR
- Distant metastasis refractory to initial treatment (at least one prior chemotherapeutic regimen which can include a single chemotherapeutic, a combination of chemotherapeutics, or biologic drugs such as bevacizumab).
- Accessible tumors for sequential biopsies Terminology Criteria for Adverse Events Version 4.0 (CTCAE v4.03) to grade 1 or better (except for < grade 2 neuropathy, alopecia, xerostomia, dysphagia, or mucositis);
- Age ≥ 18 years;
- Measurable disease, according to modified RECIST 1.1 and irRECIST (Appendix B & C);
- Eastern Cooperative Oncology Group performance status (ECOG PS) ≤ 2 (Appendix A)
- Adequate bone marrow, liver and renal function, defined by:
- Hemoglobin ≥ 10 g/dL;
- Absolute neutrophil count (ANC) ≥ 1000/μL;
- Absolute lymphocyte count ≥ 400/μL;
- Platelet count ≥ 100,000/μL;
- ALT and AST ≤ 2.5 X upper limit of normal (ULN);
- Total bilirubin ≤ 1.5 X ULN; and
- Serum creatinine ≤ 1.5 X ULN;
- Women of child-bearing potential (WOCBP) must be willing to use acceptable means of birth control;
- Men who could potentially father a child must also use birth control
- Signed informed consent
Exclusion Criteria
- Radiotherapy for primary HPVOC within 8 weeks, or radiotherapy for any other reason within 3 weeks prior to the first dose of trial treatment;
- Chemotherapy within 3 weeks prior to the first dose of trial treatment;Other cancer in the past 5 years, except for carcinoma in situ of the cervix or bladder, or non-melanomatous skin cancer;
- Inaccessible tumor or lack of consent for sequential biopsies
- Uncontrolled central nervous system (CNS) metastases (i.e. known CNS lesions that are radiographically unstable, symptomatic and/or requiring escalating doses of corticosteroids);
- Active hepatitis, known HIV, or other condition that requires immunosuppressive therapy, including current use of high dose systemic corticosteroids;
- Autoimmune disease, such as systemic lupus erythematosis or rheumatoid arthritis, that is active and requires current immunosuppressive therapy;
- Active uncontrolled serious infection;
- WOCBP who have a positive β-hCG test or are breastfeeding.
- Acute or chronic skin disorders that would interfere with subcutaneous injection of the vaccine or subsequent assessment of potential skin reactions;
- Allergies to any vaccine, that after discussion with Immunovaccine, are serious enough to warrant exclusion from this study
