Brief Summary:

This is a Phase 3, open-label, international, multi-center, efficacy, and safety study of avelumab in combination with and/or following platinum-based chemotherapy. Eligible patients must have previously untreated, histologically confirmed Stage III-IV epithelial ovarian (EOC), fallopian tube cancer (FTC), or primary peritoneal cancer (PPC) and be candidates for platinum-based chemotherapy.

The primary purpose of the study is to demonstrate if avelumab given as single agent in the maintenance setting following frontline chemotherapy or in combination with carboplatin/paclitaxel is superior to platinum-based chemotherapy alone followed by observation in this population of newly diagnosed ovarian cancer patients.

Primary Outcome Measures :
  1. Progression-Free Survival (PFS) as Assessed by Blinded Independent Central Review (BICR) [ Time Frame: Baseline to progression of disease or discontinuation from the study or death, whichever occurred first (maximum duration of 27 months) ]
    BICR assessed PFS: Duration from randomization until disease progression or death. PFS data was censored on the date of the last adequate tumor assessment for participants who did not have an event (progression of disease or death), who started a new anti-cancer therapy prior to an event or for participants with an event after 2 or more missing tumor assessments. Progression as per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1: as at least a 20 percent (%) increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 millimeters (mm). The appearance of one or more new lesions was also considered progression. Analysis was performed using Kaplan-Meier method.

    National Comprehensive Cancer Network-Functional Assessment of Cancer Therapy (NCCN-FACT) Ovarian Symptom Index-18 (FOSI-18) is an 18-itemed participant completed questionnaire, designed to assess impact of cancer therapy on ovarian cancer-related symptoms. Based on numerical point scoring of symptoms. Includes three subscales: disease-related symptoms (10 items), treatment-related side effects (5) and general function/well-being (3). Participants rated their level of symptoms for each items using 5-point scale from 0=not at all to 4=very much. Items that were negatively framed, scores were reversed for analysis so that higher scores= good quality of life. Total symptom index: total of 18 scores, ranging from 0=severely symptomatic to 72=asymptomatic. Higher FOSI-18 scores= better functioning or lower symptom burden. MP applicable only for arms 'Chemotherapy followed by Avelumab' and 'Chemotherapy + Avelumab followed by Avelumab' and OP for 'Chemotherapy followed by Observation'.

    EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). In VAS, participants rated their overall health status from 0 (worst imaginable) to 100 (best imaginable). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems, and 5=extreme problems. Published weights are available that allow for the creation of a single summary score. 57 overall scores ranged from 0 to 1, with low scores representing a higher level of dysfunction.

Criteria

Key Inclusion Criteria:

  • Histologically confirmed Stage III-IV epithelial ovarian, fallopian tube, or primary peritoneal cancer, including malignant mixed Müllerian tumors with high grade serous component
  • Patients must be candidates for platinum based chemotherapy and previously untreated
  • Patients must have completed a surgical debulking procedure, or be candidates for neoadjuvant chemotherapy
  • Availability of an archival formalin fixed, paraffin embedded (FFPE) tumor tissue block or a minimum of 15 slides
  • ECOG PS 0-1
  • Adequate hematological, renal, and liver function

Key Exclusion Criteria:

  • Non epithelial tumors or ovarian tumors with low malignant potential (ie, borderline tumors) or mucinous tumors
  • Prior systemic anti-cancer treatment for EOC, FTC, or PPC including prior immunotherapy with IL 2, IFN α, or anti PD 1, anti PD L1, anti PD L2, anti CD137, or anti cytotoxic T lymphocyte associated antigen 4 (anti CTLA 4) antibody (including ipilimumab), or any other antibody or drug specifically targeting T cell co stimulation or immune checkpoint pathways
  • Patients for whom, in the opinion of the Investigator, there is clinical benefit to administer bevacizumab as a first-line treatment and for whom bevacizumab is approved and available in this setting.
  • Cancer for which intraperitoneal cytotoxic chemotherapy is planned
  • Active autoimmune disease (some exceptions include diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroidism not requiring immunosuppressive treatment)
