Oregovomab Plus Chemo in Newly Diagnosed Patients With Advanced Epithelial Ovarian Cancer Following Optimal Debulking Surgery

Exclusion Criteria

• •1. BRCA1 or BRCA2 germline gene mutation test result with:
• •1. Pathogenic, ambiguous or inconclusive result available within 28 days prior to starting study treatment (subjects with BRCA1 or BRCA 2 variants of uncertain significance can enroll onto the study as long as there is no intent to administer PARP inhibitors for front-line maintenance therapy), or
• •2. Known BRCA1 and BRCA2 somatic mutations, if testing is performed
• •2. Known Somatic Homologous Recombination Deficiency (HRD) who will receive PARP inhibitor front-line maintenance therapy. Subjects with somatic HRD are eligible as long as there is no intent to administer PARP inhibitor front-line maintenance therapy.
• •3. Subjects with mucinous adenocarcinoma, carcinosarcoma, tumors with neuroendocrine features and low-grade adenocarcinoma.
• •4. Female subjects who are lactating and breastfeeding, or have a positive serum pregnancy test within 7 days prior to the first dose of study treatment (C1D1 for Cohort 1 or C4D1 for Cohort 2).
• •5. Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
• •6. Active autoimmune disease, such as rheumatoid arthritis, systemic lupus erythematosus (SLE), ulcerative colitis, Crohn's Disease, multiple sclerosis (MS), or ankylosing spondylitis requiring active disease modifying treatment.
• •7. Known allergy to murine proteins or hypersensitivity to any of the excipients of the oregovomab, paclitaxel, or carboplatin.
• •8. Chronically treated with immunosuppressive drugs such as cyclosporine, adrenocorticotropic hormone (ACTH), etc.
• •9. Chronic therapeutic corticosteroid use, defined as \> 5 days of prednisone or equivalent, with the exception of inhalers or those on a pre-planned steroid taper. (Note: Premedication with corticosteroids per institutional standard of care is allowed.)
• •10. Recognized acquired, hereditary, or congenital immunodeficiency disease, including cellular immunodeficiencies, hypogammaglobulinemia or dysgammaglobulinemia.
• •11. Clinically significant active infection(s) at the time of screening.
• •12. Any of the following conditions (on-study testing is not required unless it is required by a specific participating country):
• •1. Known HIV-infected subjects unless on effective anti-retroviral therapy with an undetectable viral load within 6 months, or
• •2. Known or suspected hepatitis B if active infection (subjects with chronic hepatitis B infection must have an undetectable HBV viral load on suppressive therapy, if indicated; positive surface antibody alone is not an exclusion), or
• •3. Known or suspected hepatitis C infection which has not been treated and cured unless currently on treatment with an undetectable viral load).
• •13. Uncontrolled or life-threatening diseases compromising safety evaluation.
• •14. Diagnosed or treated for another malignancy within 5 years before the first dose, or previously diagnosed with another malignancy and have any evidence of residual disease including ductal carcinoma in situ of the breast. Subjects with non-melanoma skin cancer, other carcinoma in situ if have undergone complete resection or cervix carcinoma in situ are not excluded if they have undergone complete resection. Synchronous endometrial and prior diagnosis of endometrial cancer within 5 years is not excluded if all of the following conditions are met: Stage IA, superficial myometrial invasion, without lymphovascular invasion, and not poorly differentiated subtypes including papillary serous, clear cell lesions.
• •15. Contraindications to the use of pressor agents.
• •16. Undergone more than one surgical debulking or have not recovered from surgery.
• •17. Anticipated treatment with any other anti-cancer medications, including bevacizumab, PARP inhibitors, or any investigational agent(s) during the study.
• •18. History or evidence upon physical examination of CNS disease, seizures not controlled with standard medical therapy, or any brain metastases.
• •19. Any of the following cardiovascular conditions:
• •1. Acute myocardial infarction within 6 months before the first dose of study treatment.
• •2. Current history of New York Heart Association (NYHA) Class III or IV heart failure.
• •3. Evidence of current uncontrolled cardiovascular conditions including cardiac arrhythmias, angina, pulmonary hypertension, or electrocardiographic clinically significant findings.
• •20. Unable to read or understand or unable to sign the necessary written consent before starting treatment.
• •21. May not receive any live, attenuated vaccine administered within 28 days (or 4 weeks) prior to enrollment, during the study, and for at least 90 days after the last dose of study treatment.
• •22. Subjects who receive Hyperthermic Intraperitoneal Chemotherapy (HIPEC), any other anti-cancer medications, including bevacizumab, PARP inhibitors, or any other investigational agent(s) with 3 cycles of paclitaxel and carboplatin neoadjuvant treatment prior to IDS.
