Patients with diabetes type I, vitiligo, psoriasis, hypo or hyperthyroid disease not requiring immunosuppressive treatment are eligible. Mandatory tumor biopsy must be performed prior to enrollment for all patients (unless there is a documented clinical contraindication). In addition, availability of archived FFPE tumor tissue should be confirmed. If a patient underwent tumor tissue collection within 3 months prior to enrollment with no intervening treatment, and the sample is provided, then a new de novo tumor biopsy is not required. Exclusion Criteria: * Non epithelial tumor or ovarian tumors with low malignant potential (ie, borderline tumors). * Prior therapy with an anti PD 1, anti PD L1, anti PD L2, anti CD137, or anti cytotoxic T lymphocyte associated antigen 4 (CTLA 4) antibody (including ipilimumab, tremelimumab or any other antibody or drug specifically targeting T cell co stimulation or immune checkpoint pathways). * Known symptomatic brain metastases requiring steroids. Patients with previously diagnosed brain metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to study entry, have discontinued corticosteroid treatment for these metastases for at least 4 weeks prior to study entry and are neurologically stable. * Diagnosis of any other malignancy within 5 years prior to registration, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or of the cervix. * Severe gastrointestinal conditions such as clinical or radiological evidence of bowel obstruction within 4 weeks prior to study entry, uncontrolled diarrhea in the last 4 weeks prior to enrollment, or history of inflammatory bowel disease.

Outcomes

Primary Outcomes

Overall Survival (OS)

OS is defined as the time from the date of randomization to the date of death due to any cause. OS time was summarized by treatment arm using the Kaplan-Meier method.

Time frame: From randomization until the date of first documented progression or date of deaths from any cause, whichever came first, assessed up to 30 months (based on cutoff date: 19 September 2018).

Progression Free Survival (PFS) Based on Blinded Independent Central Review (BICR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

PFS is defined as the time from date of randomization to the date of the first documentation of progression of disease (PD) or death due to any cause, whichever occurs first. PFS time was summarized by treatment arm using the Kaplan-Meier method. PFS based on BICR assessment was evaluated for this endpoint.

Time frame: From randomization to date of first documentation of PD or death due to any cause whichever was first (up to 30 months); based on cutoff date: 19 September 2018.

Secondary Outcomes

Objective Response Rate (ORR) Based on BICR Assessment

Percentage of participants achieved objective response (OR) based on BICR assessment is presented for this endpoint. OR is defined as a complete response (CR, disappearance of all target lesions) or partial response (PR, \>=30% decrease under the baseline of the sum of diameters of all target measurable lesions) according to the RECIST (version 1.1) recorded from randomization until disease progression or death due to any cause. Both CR and PR must be confirmed by repeat assessments performed no less than 4 weeks after the criteria for response are first met and before the first documentation of disease progression. Only tumor assessments performed on or before the start date of any further anti-cancer therapies are considered in the assessment of best overall response.

Time frame: Tumor assessments as assessed by BICR were conducted at every 8 weeks from screening until documented disease progression (approximately up to 30 months); based on cutoff date: 19 September 2018.
