RFS was defined as the time from surgery to the first documented recurrence of disease (intrahepatic or extrahepatic), as assessed by the investigator according to EASL and/or RECIST v1.1, or death from any cause.
Intrahepatic recurrence was defined by the appearance of one or more intrahepatic lesions with a longest diameter of > 1 cm and a typical vascular pattern of HCC on dynamic imaging (i.e., hypervascularization in the arterial phase with washout in the portal venous or late venous phase).
Extrahepatic recurrence was assessed by RECIST v1.1 as the appearance of new, measurable malignant lesions outside the liver.
Data for participants who did not have documented recurrence of disease or death were censored at the day of the last tumor assessment for participants.
Kaplan-Meier (K-M) method was used to estimate median RFS.

|
EFS was defined as the time from randomization to any of the following events, whichever occurred first: PD that precluded surgery, as assessed by the investigator according to RECIST v1.1.
PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters at prior timepoints (including baseline); local, regional, or distant disease recurrence as measured by EASL and/or RECIST v1.1; or death from any cause.

Time Frame: From randomization to death from any cause (up to 20.5 months)
|
OS was defined as the time from randomization to death from any cause.

From randomization to death from any cause (up to 20.5 months)
|
|
OS Rate at 6 Months, 12 Months, and 18 Months
Time Frame: At Months 6, 12, and 18
|
OS rate at 6, 12, and 18 months was defined as the percentage of participants who had not experienced death from any cause at 6 months, 12 months, and 18 months after randomization, respectively.
OS was defined as the time from randomization to death from any cause.

CR was defined as the disappearance of all target and non-target lesions.
Additionally, any pathological lymph nodes (whether target or non-target) must have a reduction in short axis to <10 millimeters (mm).
PR was defined as at least a 30% decrease in the sum of diameters (SOD) of all target lesions, taking as reference the baseline SOD, in the absence of CR.

ORR was defined as the percentage of participants with a radiographic OR, characterized by a CR or a PR prior to surgery, as determined by the investigator according to HCC mRECIST.
CR was defined as the disappearance of any intratumoral arterial enhancement in all target and non-target lesions.
PR was defined as an increase of at least 30% in the sum of the longest diameters of viable (contrast enhancement in the arterial phase) target lesions, taking as reference the baseline SOD of target lesions.
