Inclusion criteria

Inclusion criteria: I-1. Female Patients must be =18 years of age. I-2. Signed informed consent and ability to comply with treatment and follow-up. I-3. Patients with histologically confirmed non-mucinous epithelial ovarian cancer, primary peritoneal adenocarcinoma and / or fallopian-tube adenocarcinoma I-4. Patients with known PD-L1 status on fresh mandatory biopsy sent to central laboratory as a formalin-fixed, paraffin-embedded (FFPE) sample. - Cell pellet from pleural effusion, or ascites or lavage are not acceptable. - For core needle biopsy specimens, at least two cores should be obtained. Biopsies must be obtained in a manner that minimizes risks. If the location of the tumor renders tumor biopsy medically unsafe or not feasible, patient eligibility should be discussed with the sponsor. I-5. Patients whose disease has relapsed more than 6 months from the last dose of platinum before randomization: a) criterion for relapse can be according to RECIST v1.1, CA125 (GCIG) or clinical symptoms b) the interval between last dose of platinum and entry in the study should be free of new anti-cancer treatment, with the exception of a maintenance therapy which is allowed up to 21 days before study entry. I-6. Patients with one or 2 prior lines of chemotherapy. The last line of chemotherapy should have included platinum. I-7. Availability at the study site of a representative FFPE tumor sample or at least 15 unstained slides from debulking surgery during front-line therapy I-8. Patients must have normal organ and bone marrow function : a) Haemoglobin = 10.0 g/dL. b) Absolute neutrophil count (ANC) = 1.5 x 109/L. c) Platelet count = 100 x 109/L. d) Total bilirubin = 1.5 x institutional upper limit of normal (ULN). e) Aspartate aminotransferase /Serum Glutamic Oxaloacetic Transaminase (ASAT/SGOT)) and Alanine aminotransferase /Serum Glutamic Pyruvate Transaminase (ALAT/SGPT)) = 2.5 x ULN, unless liver metastases are present in which case they must be = 5 x ULN. f) Serum creatinine = 1.5 x institutional ULN, g) Patients not receiving anticoagulant medication who have an International Normalized Ratio (INR) =1.5 and an Activated ProThrombin Time (aPTT) =1.5 x ULN. The use of full-dose oral or parenteral anticoagulants is permitted as long as the INR or APTT is within therapeutic limits (according to site medical standard) and if the patient is on a stable dose of anticoagulants for at least two weeks at the time of randomization. h) Urine dipstick for proteinuria =65 years) yes F.1.3.1 Number of subjects for this age range 162

Exclusion criteria

Exclusion criteria: E-1. Non-epithelial tumor origin of the ovary, the fallopian tube or the peritoneum (i.e. germ cell tumors). E-2. Ovarian tumors of low malignant potential (e.g. borderline tumors) E-3. Patients with synchronous primary endometrial cancer unless both of the following criteria are met: a) stage 325 mg/day. E-18. Prior history of hypertensive crisis (CTC-AE grade 4) or hypertensive encephalopathy. E-19. Inadequately controlled HTN E-20. Clinically significant (e.g. active) cardiovascular disease, including: a) Myocardial infarction or unstable angina within = 6 months of randomization, b) New York Heart Association (NYHA) = grade 2 congestive heart failure (CHF), c) Poorly controlled cardiac arrhythmia despite medication (p

Design outcomes

Primary

MeasureTime frame
Main Objective: The primary efficacy outcome measure is investigator determined progression-free survival (PFS1) as assessed using RECIST v1.1;Secondary Objective: - Supportive secondary objectives To determine the efficacy of atezolizumab compared to placebo on: • Time from randomization to second subsequent therapy or death (TSST) • Health-related Quality of Life (HRQoL) and patient reported outcomes (PROs) as measured by EORTC QLQ-C30 and OV28 • Overall survival (OS) - Others secondary objectives To determine the efficacy of atezolizumab compared to placebo on: • Objective Response Rate (ORR) as assessed by RECIST v1.1 and irRECIST • PFS1 as assessed per irRECIST • Characterization of CA-125 tumor marker levels and their relation to tumor response and PFS1 as measured by RECISTv 1.1 and irRECIST • Time from randomization to first subsequent therapy or death (TFST) • Time from randomization to second progression (PFS2) ;Primary end point(s): Progression free-survival (PFS1). PFS1 is defined as the time from randomization until the date of the first objective radiological disease progression according to investigator assessment of RECIST version 1.1 or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomized study treatment or receives another anti-cancer therapy prior to progression;Timepoint(s) of evaluation of this end point: 278 events observed for the primary analysis. Patients who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment from their last evaluable RECIST assessment.

Secondary

MeasureTime frame
Secondary end point(s): Secondary supportive objectives To determine the efficacy of atezolizumab compared to placebo on: • Time from randomization to second subsequent therapy or death (TSST) • Health-related Quality of Life (HRQoL) and patient reported outcomes (PROs) as measured by EORTC QLQ-C30 and OV28 •Overall survival (OS) Others secondary objectives To determine the efficacy of atezolizumab compared to placebo on: • Objective Response Rate (ORR) as assessed by RECIST v1.1 and irRECIST • PFS1 as assessed per irRECIST • Characterization of CA-125 tumor marker levels and their relation to tumor response and PFS1 as measured by RECISTv 1.1 and irRECIST • Time from randomization to first subsequent therapy or death (TFST) • Time from randomization to second progression (PFS2) Others secobdary objectives To determine the efficacy of atezolizumab compared to placebo in the PD-L1-ve and PD-L1 +ve subgroups To assess the safety and tolerability of atezolizumab compared to placebo To evaluate the impact of treatment and disease on resource use as measured by different criteria including EuroQoL 5 Dimension (EQ-5D) questionnaire Exploratory objectives 1. To explore pre-planned subgroups analyses of efficacy (PFS) based on relevant potential prognostic factors, including stratification factors, as well as on the performance or not of secondary cytoreductive surgery. 2. To evaluate the relationship between the expression of PD-L1, tumor mutational load and intraepithelial TILs with ORR and PFS. 3. To assess immune-related and other potential predictive and prognostic exploratory biomarkers in fresh/archival tissue and blood and their association with disease status and/or efficacy as defined by ORR and PFS. 4. To evaluate the relationship between PD-L1, TILs and biomarker status in archival tissue and in fresh tumor specimens. 5. To evaluate the utility of biopsy at the time of apparent disease progression to distinguish apparent inc
