What this study is testing
Progression-free survival (PFS): To determine the efficacy by progression free survival (using investigator assessment of scans according to RECIST v1.1) of oregovomab compared to placebo when administered with chemotherapy (paclitaxel/carboplatin) to subjects with newly diagnosed ovarian cancer (FIGO Stage III or IV) who have undergone optimal debulking surgery
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- Adults 18 years old or older
- Adequate renal function: a. Creatinine ≤ 1.5 times ULN
- ECOG Performance Status of 0 or 1
- For women of childbearing potential, must be willing to avoid pregnancy by using a highly effective method of contraception from the first dose of study treatment to 6 months after last dose of study treatment. Adequate contraception is defined in Section 8.2.5. (Belgium and South Korea Only: Use of a highly effective method of contraception from 28 days before first dose).

- Willingness and ability to complete patient quality of life questionnaires.
You likely can't join if
- BRCA1 or BRCA2 germline gene mutation test result with: a. Pathogenic, ambiguous or inconclusive result available within 28 days prior to starting study treatment. Subjects with BRCA1 or BRCA2 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 b. Known BRCA1 and BRCA2 somatic mutations, if testing is performed
- Recognized acquired, hereditary, or congenital immunodeficiency disease, including cellular immunodeficiencies, hypogammaglobulinemia or dysgammaglobulinemia.
- Clinically significant active infection(s) at the time of screening.
- Any of the following conditions (on-study testing is not required unless it is required by a specific participating country): a. Known HIV-infected subjects unless on effective anti-retroviral therapy with an undetectable viral load within 6 months, or b. 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 c. Known or suspected hepatitis C infection which has not been treated and cured unless currently on treatment with an undetectable viral load).
- Uncontrolled or life-threatening diseases compromising safety evaluation.
- 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.

- Willingness and ability to complete patient quality of life questionnaires.
- Subjects with newly diagnosed epithelial adenocarcinoma of ovarian, fallopian tube or peritoneal origin FIGO Stage III or IV disease.
- Eligible histologic epithelial cell types: high grade serous adenocarcinoma, high grade endometrioid adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, or adenocarcinoma not otherwise specified (N.O.S.).
- Completed debulking surgery (either primary debulking surgery or interval debulking surgery at the discretion of the investigator), as defined below: a. For subjects who undergo primary debulking surgery (Cohort 1 - Primary Surgery): i. Subject must receive initial dose of paclitaxel 175 mg/m2 given intravenously, and carboplatin AUC 6 IV every 3 weeks (21 days) for 6 cycles. Carboplatin total dose given as 5 consecutive daily pulse doses, for subjects who experiences significant grade 3 or higher emesis. Subsequent dose modifications will be instituted per protocol. Cycle 1 of chemotherapy ± oregovomab/placebo must be anticipated to occur within 6 weeks after primary debulking surgery, and ii. The primary debulking surgery is optimal, R1 or R0 (defined as R1, macroscopic less than 1 cm in diameter, or R0, microscopic or no evidence of tumor). Assessment of intra-abdominal optimal debulking will be determined at the time of the surgical procedure and not by postsurgical imaging (i.e., CT scan). Assessment of intra-abdominal optimal debulking will be determined at the time of the surgical procedure and not by post-surgical imaging (i.e., CT scan). b. For subjects who will undergo interval debulking surgery (IDS) (Cohort 2 – NACT+/Interval Surgery): i. Prior to IDS, subject must have received neoadjuvant treatment with 3cycles of paclitaxel and carboplatin a) paclitaxel must have been started at an initial dose of 175 mg/m2 given intravenously (IV) every 3 weeks (21 Days) ). If the subject experienced grade 3 or 4 adverse events with paclitaxel 175mg/m2, dose reduction to 135 mg/m2 is allowed for cycles 2 and/or 3. b) Carboplatin initial dose must have been an area under the curve (AUC) 5-6 IV approximately every 3 weeks (21 Days) ii. Once subjects are enrolled on the protocol, they must receive paclitaxel 175mg/m2 IV and carboplatin AUC 5-6 IV every 3 weeks starting cycle 4. Subsequent dose modifications will be instituted per protocol. Cycle 4 of chemotherapy ± oregovomab/placebo must be anticipated to occur within 6 weeks after interval debulking surgery, and iii. The interval debulking surgery is optimal, R1 or R0 (defined as R1, macroscopic less than 1 cm in diameter, or R0, microscopic or no evidence of tumor). Assessment of optimal debulking of intra-abdominal disease will be determined at the time of the surgical procedure and not by post-surgical imaging (i.e., CT scan).
