Autologous OC-DC Vaccine in Ovarian Cancer

• Clinical Response [ Designated as safety issue: Yes ]
  Clinical Response will be determined by RECIST criteria. Response rate is the proportion of patients that achieve CR or PR.
• Dose limiting toxicity [ Designated as safety issue: Yes ]
  Dose-limiting toxicity is defined as: any Grade 3 or higher allergic, autoimmune or injection site reaction or any Grade 4 hematologic or non-hematologic toxicity (except fever).
• Immune Response Immune Response [ Designated as safety issue: Yes ]
  Immune response will be evaluated by IFN-g ELISPOT analysis of tumor-reactive T cells, and in HLAA2+ subjects, by tetramer analysis of Her-2 specific T cells in peripheral blood. Response is defined by a 3 fold increase relative to pre-vaccination.

This is a three cohort sequential clinical trial for subjects with recurrent ovarian, fallopian tube or primary peritoneal cancer to determine the feasibility and safety as well as immunogenicity of OC-DC, an autologous vaccine comprised of autologous dendritic cells (DC) loaded in vitro with lysate from autologous oxidized tumor cells, administered intranodally alone or in combination with intravenous Bevacizumab and Cyclophosphamide.

• Ovarian Cancer

Inclusion Criteria

• Subject has had prior cytoreductive surgery yielding tumor for lysate preparation.
• Lysate must meet release criteria
• Subject is 18 years of age or older.
• Subject has an ECOG performance status of less than 1.
• Subject has a life expectancy of greater than 6 months.
• Subject must understand and sign the study specific informed consent.
• Subject may have received chemotherapy or other therapy after harvest of tumor and prior to enrollment. Subjects who have achieved complete response following chemotherapy are still eligible for participation
• Subject is platinum-sensitive (progression-free interval greater than 6 months prior to recent recurrence) or platinum-resistant (progression-free interval less than 6 months prior to recent recurrence).
• Subject has recovered from toxicities of prior chemotherapy or other therapy (to grade 2 or less).
• Subject may have received prior investigational therapy (including immune therapy).
• Subject may have received prior hormonal therapy.
• Subject may have received prior radiation therapy (except to inguinal region) but must have completed such therapy prior to enrollment.
• Subject has had at least 4 weeks of postoperative recovery from surgery prior to enrollment to ensure complete wound healing. Subjects with bowel resections at surgery who enroll in cohort 2 will begin protocol at least 42 days after surgery if debulking surgery had comprised of bowel resection or other bowel surgery.
• Subjects who screen fails can be re-enrolled if the causation of the screen fail has been corrected.

• Subject has a chronic or acute hepatitis B infection.
• Subject has positive test result at the screening visit for one or more of the following:
• HTLV-1/2
• Anti-HIV 1 Antibody (-HIV-1)
• Subject requires or is likely to require more than a two-week course of corticosteroids for intercurrent illness. Subject must complete the course of corticosteroids 2 weeks before screening to meet eligibility.
• Subject has renal insufficiency as defined by a serum creatinine greater than 2.2 mg/dl or BUN greater than 40 mg/dl. Note: If creatinine is greater than 1.5 x ULN, creatinine clearance must be greater than 60ml/min.
• Subject has proteinuria greater than 3.5 gm over 24 hrs are not eligible for the study (cohort 2 only)
• Subject with liver failure as defined by a serum total bilirubin greater than 2.0 and/or serum transaminases greater than 3X the upper limits of normal.

• Subject has organ allografts.
• Subject is receiving medication(s) that might affect immune function. Use of H2 antagonists are prohibited as are all antihistamines five days before and five days after each injection of study vaccine. However, NSAIDS including COX-2 inhibitors, acetaminophen or aspirin are permitted.
• Subject has clinical symptoms or signs of partial or complete gastrointestinal obstruction or who require parenteral hydration and/or nutrition (For cohort 2 and cohort 3).
• Subjects with a History of bowel obstruction, including sub-occlusive disease, related to the underlying disease and history of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess.
