An Immuno-therapy Study to Evaluate the Effectiveness, Safety and Tolerability of Nivolumab or Nivolumab in Combination With Other Agents in Patients With Advanced Liver Cancer

An 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 treatment and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory finding), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment.

Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, and requires inpatient hospitalization or causes prolongation of existing hospitalization.

Number of participants who died during the study.

Participants with abnormalities in liver function tests related to potential drug-induced liver injury. Blood samples were collected and analyzed for liver function parameters, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Abnormalities were assessed relative to the upper limit of normal (ULN) for each parameter.

Abbreviations: ALT = Alanine Aminotransferase; AST = Aspartate Aminotransferase; ULN = Upper Limit of Normal.

Number of participants with thyroid-related laboratory abnormalities during the study. Blood samples were collected and analyzed for thyroid function markers (FT3, FT4). Abnormalities were assessed against LLN and ULN for each parameter.

Abbreviations: FT3 = Free T3; FT4 = Free T4; LLN = Lower Limit of Normal; ULN = Upper Limit of Normal; TSH = Thyroid Stimulating Hormone

Objective response rate (ORR) is defined as the percent of all treated participants whose best overall response (BOR) is either complete response (CR) or partial response (PR) by BICR per Response Evaluation Criteria in Solid Tumors (RECIST v1.1). Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD): At least a 20% increase in the sum of the 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 also demonstrate an absolute increase of at least 5mm (Note: The appearance of 1or more new lesions is also considered progression).

The number of participants whose best overall response (BOR) is CR in the population of interest. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.

The percentage of participants whose best overall response (BOR) is CR, PR or SD in the population of interest. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Failure to meet criteria for complete or partial response, in the absence of progressive disease. Progressive Disease (PD): At least a 20% increase in the sum of the 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 also demonstrate an absolute increase of at least 5mm (Note: The appearance of 1or more new lesions is also considered progression).

DOR is defined as the time from the first documented objective response (either complete or partial response) until the date of disease progression or death from any cause, whichever occurs first.

Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.

Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Time to Progression (TTP) is defined from the date of randomization (Cohort 3, 4, 6) or the date of first dose (Cohort 1, 2, 5) to the date of the first objectively documented disease progression. Participants who have not progressed as assessed by radiography will be censored at the last tumor assessment date prior to subsequent anti-cancer therapy. Participants who have no on-study tumor assessments were censored at the date of randomization.

In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm (Note: The appearance of 1or more new lesions is also considered progression).

TTP rate is defined as the percentage of participants without disease progression at select time points (milestones) during the study.

In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm (Note: The appearance of 1or more new lesions is also considered progression).

PFS is defined as the time from randomization date or first dosing date of study medication to the date of the first objectively documented tumor progression or death due to any cause. Participants who die without a reported prior progression will be considered to have progressed on the date of their death. Participants who did not progress or die will be censored on the date of their last tumor assessment.

Progressive Disease (PD): At least a 20% increase in the sum of the 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 also demonstrate an absolute increase of at least 5mm (Note: The appearance of 1or more new lesions is also considered progression).

OS is defined as the time from randomization date or first dosing date of study medication to the date of death (due to any cause). Participants who were alive were censored at the last known alive dates.

OS rate is defined as the percentage of participants who are still alive at certain time points during the study.

Cmax is the maximum observed serum concentration.

Tmax is the time taken to reach the maximum observed serum concentration (Cmax).

AUC (TAU) is the area measured under the concentration-time curve taken over the dosing interval.

Ctrough is the lowest observed serum concentration.

Serum Concentration Achieved at the End of the Infusion (Ceoinf) refers to the amount of drug present in the blood (serum) immediately after the completion of an infusion. It represents the concentration measured at the exact time the infusion ends, before any significant elimination or distribution occurs.

AI_Cmax is ratio of an exposure measure at steady state to that after the first dose (exposure measure includes Cmax)

AI_AUC is accumulation index ratio of AUC at steady state to that after the first dose

Effective half-life is defined as the time it takes for the amount of a drug in the body to decrease by half.
