Brief summary: This is a Phase 2 randomized study with two treatment arms to compare the effectiveness of oregovomab (a murine monoclonal antibody directed against cancer antigen 125 (CA125)) when combined with first-line chemotherapy (carboplatin and paclitaxel) to first-line chemotherapy (carboplatin and paclitaxel alone) in female patients with advanced ovarian cancer.

Detailed description: Oregovomab is an investigational drug previously used in clinical trials as an immunotherapeutic treatment of ovarian cancer patients whose tumor cells express the tumor associated antigen, CA125. The active component of oregovomab is the activated murine monoclonal antibody B43.13, an immunoglobulin G1k (IgG1k) subclass immunoglobulin that binds with high affinity (1.16E10/M) to CA125.

CA125 is a surface glycoprotein antigen that is expressed on more than 80% of all non-mucinous epithelial ovarian carcinomas where it occurs at elevated levels in the serum of patients with ovarian cancer. Little is known about its biological function. CA125 is associated with a large molecular weight mucin-like glycoprotein complex of 200-250 kilodaltons (kDa) and its genetic structure has recently been elucidated. There is good evidence to suggest that CA125 is a relevant target antigen for antigen-mediated immunotherapy of ovarian cancer.

The study will compare the effectiveness of oregovomab (a murine monoclonal antibody directed against cancer antigen 125 (CA125)) when combined with first-line chemotherapy (carboplatin and paclitaxel) to first-line chemotherapy (carboplatin and paclitaxel alone) in female patients with advanced ovarian cancer.

Eligibility criteria: Inclusion Criteria:

* able to sign informed consent and provide authorization permitting release of personal health information
* have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1

Exclusion Criteria:

* have an active autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus (SLE), ulcerative colitis, Crohn's Disease, multiple sclerosis (MS), ankylosing spondylitis)
* have a known allergy to murine proteins or have had a documented anaphylactic reaction to any drug, or cannot tolerate cyclophosphamide

* have severe renal insufficiency with serum creatinine \>1.6 mg/dL
* have concomitant diseases or treatments that may confound the results of the study, which may preclude the completion of the protocol or may mask adverse reactions
* are to be tested with other medications during treatment
* are unable to read or understand or unable to sign the necessary written consent before starting treatment
