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).
    
      This is a phase Ib/II clinical trial. DPX-E7 is a therapeutic vaccine, intended to treat
      HPV-related head and neck, cervical or anal cancer. DPX-E7 is an investigational vaccine and
      the FDA (the U.S. Food and Drug Administration) has not approved DPX-E7 vaccine as a
      treatment for any disease.
      DPX-E7 is being tested in humans for the first time. DPX-E7 is a kind of immunotherapy that
      will make the immune system to elicit an anti-tumor response by generating CD8+ T-cells. CD8+
      T-cells play a very important role in fighting against viral infections
    
        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.

             to warrant exclusion from this study
