A Phase 1b Trial of Lenvatinib Plus Nivolumab in Subjects With Hepatocellular Carcinoma

Part 1: Number of Participants With Dose-Limiting Toxicities (DLTs)

时间窗: Cycle 1 (Cycle length = 28 days)

DLT was graded according to Common Terminology Criteria for Adverse Events version 4.03 (CTCAE v4.03). DLT was defined as any of the following hematological or non-hematological toxicities considered to be at least possibly related to lenvatinib and/or nivolumab occurring during Cycle 1: 1) Febrile neutropenia or Grade 4 neutropenia for \>7 days; 2) Grade 4 thrombocytopenia and Grade 3 thrombocytopenia with bleeding; 3) Grade 4 anemia; 4) Clinical deterioration manifested by drug-related hepatic decompensation; 5) \>=Grade 3 non-hematological laboratory abnormalities with clinical symptoms that persisted; 6) Other Grade 3 toxicity lasting \>3 days or Grade 4 non-hematological toxicity of any duration; 7) Grade 2 uveitis, eye pain, or blurred vision that did not respond to topical therapy; 8) Failure to administer 8 or more dose of the planned administration number of study drug in Cycle 1 as a result of treatment-related toxicity.

Mean Change From Baseline in Vital Sign: Weight

时间窗: Baseline, up to Month 53

Mean change from baseline in weight were evaluated.

Mean Change From Baseline in Vital Sign: Body Mass Index

时间窗: Baseline, up to Month 53

Mean change from baseline in body mass index were evaluated.

Part 1 and Part 2: Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

时间窗: From the first dose of study drug until 30 days after the last dose (up to 53 months)

A TEAE was defined as an adverse event (AE) that emerged during treatment and until the 30 days after the last dose or until the participants initiated new anticancer therapy, whichever was earlier, was absent at pretreatment (Baseline) or reemerged during treatment, was present at pretreatment (Baseline) but stopped before treatment, or worsened in severity during treatment relative to the pretreatment state, when the AE was continuous. An SAE was any untoward medical occurrence that at any dose: resulted in death, was life-threatening (that is, participant was at immediate risk of death from AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug).

Mean Change From Baseline in Vital Sign: SpO2 (Oxygen Saturation)

时间窗: Baseline, up to Month 53

Mean change from baseline in SpO2 were evaluated.

Number of Participants With Treatment-Emergent Markedly Abnormal Laboratory Values (TEMAVs)

时间窗: From the first dose of study drug until 30 days after the last dose (up to 53 months)

Treatment-emergent markedly abnormal laboratory value was defined as a postbaseline laboratory value with grade 3 or higher, and with a grade increase from baseline, (that is \[i.e.\] increasing grade 0 to 3 or higher, grade 1 to 3 or higher, grade 2 to 3 or higher, grade 3 to 4 or 5, grade 4 to 5). Test abnormalities were graded by Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 as Grade 1 =mild; Grade 2 =moderate; Grade 3/Grade 4 =severe/life-threatening, Grade 5 =death.

Number of Participants With Highest Post-Baseline Values for Eastern Cooperative Oncology Group Performance Status (ECOG-PS) Scale

时间窗: Baseline, up to Month 53

Performance status assessments were based on 5-grade ECOG scale (from 0 to 4), where 0=fully active, able to carry on all pre-disease performance without restriction; 1=restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature (e.g., light house work, office work); 2=ambulatory and capable of all self-care but unable to carry out any work activities, up and about more than 50% of waking hours; 3=capable of only limited self-care, confined to bed or chair more than 50% of waking hours; 4=completely disabled, cannot carry on any self-care, totally confined to bed or chair; 5=dead.

Change From Baseline in Left Ventricular Ejection Fraction (LVEF)

时间窗: Baseline, up to Month 53

Change from baseline in left ventricular ejection fraction (LVEF) were evaluated by multigated acquisition scan (MUGA) or echocardiogram.
