A Study of Safety, Tolerability and Pharmacokinetics of Nivolumab in Chinese Subjects With Previously Treated Advanced or Recurrent Solid Tumors

A drug related adverse event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study drug that has a causal relationship with the treatment. AEs are graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (Version 4.03) (NCI CTCAE) guidelines where Grade 3= Severe and Grade 4= Life-threatening.

A drug related serious adverse event (SAE) is any untoward medical occurrence that at any dose: results in death; is life-threatening; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; or is an important medical event that has a casual relationship with the treatment. SAEs are graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (Version 4.03) (NCI CTCAE) guidelines where Grade 3= Severe and Grade 4= Life-threatening.

The number of participants with the following laboratory abnormalities from the following on-treatment evaluations:

• ALT or AST > 3 x ULN, > 5 x ULN, > 10 x ULN and > 20 x ULN
• Total bilirubin > 2 x ULN
• Concurrent (within 1 day) ALT or AST > 3 x ULN and total bilirubin > 2 x ULN
• Concurrent (within 30 days) ALT or AST > 3 x ULN and total bilirubin > 2 x ULN

The number of participants with Grade 3-4 laboratory results according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0. Note: Grade 4 Toxicities not included in the below table if there were no participants that experienced Grade 4 in that category.

Grade 3: prolonged recurrence of symptoms following initial improvement; hospitalization indicated for other clinical sequelae [e.g., renal impairment, pulmonary infiltrates].

Grade 4: Life-threatening; pressor or ventilatory support indicated.

Best overall response (BOR) was assessed by the investigator using Response Evaluation Criteria in Solid Tumor (RECIST v1.1). Complete Response (CR) is defined as a disappearance of all target lesions. Partial Response (PR) is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Progressive Disease (PD) is defined as at least a 20% 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).

Duration of response is defined as the time from the date of first response (CR or PR) to the date of the first documented tumor progression as determined using RECIST 1.1 or death due to any cause, whichever occurs first. Participants who remain alive and have not progressed will be censored on the date of their last tumor assessment. Participants who started subsequent therapy without a prior reported progression will be censored at the last tumor assessment prior to initiation of the subsequent anticancer therapy. Complete response (CR) is defined as a disappearance of all target lesions and partial response (PR) is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Other tumor types include: gastric, melanoma, neuroblastoma, colorectal cancer, cervical cancer, duodenal papillary carcinoma, and gallbladder carcinoma.

Objective response rate (ORR) is defined as the percentage of all treated participants whose best overall response (BOR) is either a complete response (CR) or partial response (PR) by investigator using Response Evaluation Criteria in Solid Tumor (RECIST v1.1). Complete response (CR) is defined as a disappearance of all target lesions and partial response (PR) is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Other tumor types include: gastric, melanoma, neuroblastoma, colorectal cancer, cervical cancer, duodenal papillary carcinoma, and gallbladder carcinoma.

Response rate at 24 weeks is defined as the percentage of all treated participants who have CR or PR by 24 weeks. Complete response (CR) is defined as a disappearance of all target lesions and partial response (PR) is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Other tumor types include: gastric, melanoma, neuroblastoma, colorectal cancer, cervical cancer, duodenal papillary carcinoma, and gallbladder carcinoma.

Disease control rate (DCR) at 24 weeks is defined as the percentage of all treated participants who have CR, PR or SD by 24 weeks. Complete Response (CR) is defined as a disappearance of all target lesions. Partial Response (PR) is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Other tumor types include: gastric, melanoma, neuroblastoma, cervical cancer, duodenal papillary carcinoma, and gallbladder carcinoma.

The number of participants with the following anti-drug responses:

• Baseline ADA positive: all participants with baseline ADA positive samples.
• ADA Positive: participants that have at least one ADA positive sample relative to baseline at any time after initiation of treatment.
• ADA negative: participants that have no ADA positive samples after the initiation of treatment.
