For patients who are HIV positive, histologically or cytologically confirmed diagnosis of cancer at any site that is positive for HPV-16 and/or HPV-18 by the institutionally approved assay. Tumors may be positive for more than 1 HPV subtype as long as HPV-16 and/or HPV-18 is present. Note: For the first 6 patients, only cervical, vulvar, or vaginal cancers will be enrolled.

Exclusion Criteria:

1. Any concurrent chemotherapy, investigational product (IP), biologic, or hormonal therapy for cancer treatment; receipt of any investigational or approved anticancer therapy (chemotherapy, targeted therapy, biologic therapy, monoclonal antibodies, etc.) within 21 days or 5 half lives, whichever is shorter, prior to the first dose of MEDI0457; concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.

2. Major surgical procedure or significant traumatic injury within 28 days before the first dose of study drug or anticipation of the need for major surgery during the course of study treatment.

Hearing loss of Grade 3 or lower and peripheral neuropathy of Grade 2 or lower is allowed. Subjects with Grade >/= 2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician. Subjects with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.

4. Current or prior use of immunosuppressive medication within 14 days prior to first study dose, with the exception of intranasal and inhaled corticosteroids or systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or equivalent. Steroids as premedication for hypersensitivity reactions due to radiographic contrast agents are allowed.
