AE=any new unfavorable symptom, sign or disease or worsening of a preexisting condition that may not have a causal relationship with treatment.

SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity or drug dependency/abuse; is life-threatening, an important medical event or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible or missing relationship to study drug. Death=during the study and up to 28 days past study discontinuation. The select AEs were determined using the Medical Dictionary for Regulatory Activities (MedDRA, v15.1) and graded using the Cancer Therapy Evaluation Program Common Terminology Criteria for Adverse Events (CTCAE), Version 3.0.

All participants who received at least 1 dose or any partial dose of nivolumab were analyzed.

Alkaline phosphatase (ALP), Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Creatinine and Total Bilirubin. National Cancer Institute Common Terminology Criteria (CTC) version (v) 3.0 was used to determine Grade (Gr). Abnormal values for ALP, ALT and AST were based on grades; Gr 1: > 1.0 - 2.5 * upper limits of normal (ULN); Gr 2: > 2.5 - 5.0 * ULN; Gr 3: > 5.0 - 20.0 * ULN; Gr 4: > 20.0 * ULN. Abnormal values for Creatinine were based on Gr 1: > 1.0 - 1.5*ULN; Gr 2: > 1.5 - 3.0*ULN; Gr 3: > 3.0 - 6.0*ULN; Gr 4: > 6.0*ULN. Abnormal values for Total Bilirubin were based on Gr 1: > 1.0 - 1.5 * upper limits of normal (ULN); Gr 2: > 1.5 - 3.0 * ULN; Gr 3: > 3.0 - 10.0 * ULN; Gr 4: > 10.0 * ULN.

All participants who received at least 1 dose or any partial dose of nivolumab who underwent the laboratory test.

Classification of participants host immune response was based on the following definitions: Anti-Drug Antibody (ADA) Positive Subjects have with at least one ADA positive sample at any time after initiation of treatment. ADA positive subjects were further classified into categories with Persistent Positive defined as an ADA positive sample at 2 or more sequential timepoints at least 8 weeks apart.

All participants who received at least 1 dose or any partial dose of nivolumab and were ADA-evaluable were analyzed.

Tumor response was evaluated by the sponsor based on tumor assessments by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.0. Objective response rate (ORR) was defined as the proportion of participants who's confirmed best overall response (BOR) is either complete (CR) or partial (PR), where the denominator is the number of treated participants in the population of interest. Response was based on tumor measurements. Responders= complete response (CR) or partial response (PR). CR=disappearance of all target and non-target lesions; PR=at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter. 95% Confidence intervals (CIs) were computed using the Clopper Pearson method.

All participants who received at least 1 dose or any partial dose of nivolumab with an evaluable tumor response were analyzed.

Duration of tumor response (DOR) was calculated from the first date of response of complete response (CR) or partial response (PR) to the date of the first progressive disease (PD) or the date of death. Duration of response was censored at the last tumor assessment date if a responder did not have PD or death. Nonresponders were not included in the analysis. Median DOR was estimated by Kaplan-Meier analysis.

All participants who received at least 1 dose or any partial dose of nivolumab with a measurable tumor response were analyzed.

Nivolumab in human serum was assayed by PPD® (Richmond, Virginia) using a cross-validated enzyme-linked immunosorbent assay (ELISA). Blood samples were assessed at all doses from a subset of participants. The pharmacokinetic (PK) parameter of Cmax was measured in micrograms per milliliter (µg/mL).

All participants who received at least 1 dose or any partial dose of nivolumab and had adequate PK profiles.

Hemoglobin, Lymphocytes, Neutrophils, Platelets and Leukocytes. National Cancer Institute Common Terminology Criteria (CTC) version (v) 3.0 was used to determine Grade (Gr). Abnormal values for Hemoglobin were based on Gr 1: 10.0 - less than (<) lower limit of normal (LLN); Gr 2: 8.0 - < 10.0; Gr 3: 6.5 - < 8.0; Gr 4: < 6.5. Abnormal values for Lymphocytes were based on Gr 1: 0.8 - < 1.5; Gr 2: 0.5 - < 0.8; Gr 3): 0.2 - < 0.5; Gr 4: < 0.2. Abnormal values for Neutrophils were based on Gr 1: 1.5 - < 2.0; Gr 2: 1.0 - < 1.5; Gr 3: 0.5 - < 1.0; Gr 4: < 0.5. Abnormal values for Platelets were based on Gr 1: 75.0 - < lower limits of normal (LLN); Gr 2: 50.0 - < 75.0; Gr 3: 25.0 - < 50.0; Gr 4: < 25.0. Abnormal values for Leukocytes were based on Gr 1: 3.0 - < LLN; Gr 2: 2.0 - < 3.0; Gr 3: 1.0 - < 2.0; Gr4: < 1.0.
