Inclusion Criteria:

  1. Eighteen years of age or older at the time written informed consent is obtained
  2. Newly diagnosed, histologically confirmed FIGO stage III or IV EOC (high-grade serous or high-grade endometrioid)
  3. After primary debulking surgery or after interval debulking surgery; residual disease after surgery with optimal resection as R0 or R1 (R0 is defined as no macroscopic residual disease, R1 is defined as macroscopic residual disease with a maximal diameter of <1 cm)
  4. Known BRCA status; if BRCA mutation status not known, results of BRCA testing must be available before randomization
  5. Laboratory criteria:

    5.1. White blood cells >4000/mm3 (4.0×109/L) 5.2. Neutrophil count >1500/mm3 (1.5×109/L) 5.3. Hemoglobin ≥8 g/dL (80 g/L) 5.4. Platelet count ≥100,000/mm3 (100×109/L) 5.5. Total bilirubin <2× upper limit of normal (ULN) (benign hereditary hyperbilirubinemias, e.g., Gilbert's syndrome, are permitted) 5.6. Serum alanine aminotransferase, aspartate aminotransferase, and creatinine <2×ULN 5.7. Blood urea nitrogen <2×ULN

  6. Adequate coagulation parameters:

    6.1. Activated partial thromboplastin time ≤1.5×ULN 6.2. International normalized ratio ≤1.5

  7. ECOG performance status 0-2
  8. Patients of child-bearing potential and their partners who are sexually active must agree to the use of 2 highly effective forms of contraception from the patient's signing of the ICF until 6 months after the last/final dose of first-line Pt-based adjuvant chemotherapy or IMP, whichever occurs later:

    a. Condom with spermicide and one of the following:

    • Oral contraceptive or hormonal therapy (e.g., hormone implants)
    • Placement of an intra-uterine device (IUD)

    Acceptable non-hormonal birth control methods include:

    1. Total sexual abstinence from the patient's signing of the ICF until 6 months after the last/final dose of first-line Pt-based adjuvant chemotherapy or IMP, whichever occurs later
    2. Vasectomized sexual partner plus male condom with spermicide and participant assurance that partner received post-vasectomy confirmation of azoospermia
    3. Tubal occlusion plus male condom with spermicide
    4. IUD plus male condom with spermicide. Provided coils are copper-banded.

    Acceptable hormonal methods include:

    1. Etonogestrel implants (e.g., Implanon, Norplan) plus male condom with spermicide
    2. Normal and low dose combined oral pills plus male condom with spermicide
    3. Norelgestromin/ethinyl estradiol transdermal system plus male condom with spermicide
    4. Intravaginal device plus male condom with spermicide (e.g., ethinyl estradiol and etonogestrel)
    5. Cerazette (desogestrel) plus male condom with spermicide. Cerazette is currently the only highly efficacious progesterone-based pill.
  9. Signed informed consent and ability to comprehend its content

Exclusion Criteria:

  1. Non-epithelial ovarian carcinoma or mixed epithelial histology
  2. Borderline tumors (tumors of low malignant potential)
  3. First-line Pt-based adjuvant chemotherapy already started after surgery
  4. Intention to treat with intraperitoneal chemotherapy
  5. Previous or concurrent radiotherapy to the abdomen and pelvis
  6. Major surgery (with the exception of debulking surgery) within 3 weeks before informed consent signature or patient has not recovered from any effects of any major surgery
  7. Malignancy other than EOC, except malignancy that has been in complete remission for a minimum of 3 years and except carcinoma in situ of the cervix or non-melanoma skin carcinomas that have been definitively treated
  8. Use of any immunotherapy in the past (e.g., anti-PD-1/PD-L1 or other immune checkpoint inhibitors, therapeutic vaccines, adoptive cell therapy, cytokines); in case of uncertainty, discuss with the medical monitor
  9. Symptomatic uncontrolled brain or leptomeningeal metastases. A scan to confirm the absence of brain metastases is not required. Patients with spinal cord compression may be considered if they have received definitive treatment for this and evidence of clinically stable disease for 28 days.
  10. Co-morbidities:

    10.1. HIV positive 10.2. Active hepatitis B (HBV) and/or C (HCV), active syphilis 10.3. Evidence of active bacterial, viral, or fungal infection requiring systemic treatment 10.4.

Uncontrolled hypertension 10.4.5. Myocardial infarction or ventricular arrhythmia or stroke within a 6-month period before inclusion, ejection fraction <40% or serious cardiac conduction system disorders, if a pacemaker is not present 10.5. Pericardial effusion of any CTCAE grade 10.6. Severe chronic obstructive pulmonary disease defined as grade C and D according to Global Initiative for Obstructive Lung Disease 10.7. Patients considered a poor medical risk due to other serious, uncontrolled medical disorders, non-malignant systemic diseases or active, uncontrolled infections 10.8. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study treatment, or is not in the best interest of the patient to participate 10.9. Active autoimmune disease requiring treatment 10.10. History of severe forms of primary immune deficiencies 10.11. History of anaphylaxis or other severe reactions following vaccination 10.12. Psychiatric or social conditions which, in the investigator's opinion, would prevent participation in the study

  11. Known hypersensitivity to any constituent of IMP
  12. Systemic immunosuppressive therapy for any reason (except inhaled / intranasal steroids and short-term systemic steroids <30 days duration and ≤10 mg prednisone-equivalent per day are allowed)
  13. Participation in a clinical trial using experimental therapy within the last 4 weeks before informed consent signature
  14. Pregnant or breast feeding, or expecting to conceive children within the projected duration of the study treatment
