An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment. A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization.

Participants who died with any cause are considered in the analysis.

Criteria for Dose-Limiting Toxicities (DLTs): Hepatic DLTs (excluding HCC): Grade (Gr) 4 elevations in AST, ALT, ALP, or total bilirubin. Gr 3 elevations in AST, ALT, or ALP \>5 days, with symptoms, or bilirubin \>2xULN without cholestasis. Gr 2 AST or ALT with symptomatic liver inflammation. AST or ALT \>3xULN and bilirubin \>2xULN without cholestasis. Hepatic DLTs for HCC: AST or ALT \>10xULN for \>2 weeks. AST or ALT \>15xULN. Total bilirubin \>8xULN (elevated at entry) or \>5xULN (normal at entry). ALT ≥10xULN and bilirubin ≥2xULN or baseline, without other causes. Hematologic DLTs: Gr 4 neutropenia ≥7 days. Gr 4 thrombocytopenia. Gr 3 thrombocytopenia with bleeding or platelet transfusion. Febrile neutropenia. Gr 3 hemolysis requiring intervention. Gr 4 anemia not due to underlying disease. Dermatologic DLTs: Gr 4 rash. Gr 3 rash not improving to ≤Gr 1 after 1-2 week delay. Other DLTs: Gr 2-4 eye issues, Gr 3-4 toxicities, excluding specific Gr 3 events like nausea, fever.

Blood samples were collected to assess the abnormalities in laboratory parameters. The laboratory parameters were graded by Common Terminology Criteria for Adverse Events (CTCAE). Grade 3=Severe; Grade 4=Life-threatening.

ORR is defined as the percentage of participants with a confirmed Best overall response of Complete Response (CR) or Partial Response (PR) by 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.

DOR is defined for participants who have a confirmed CR or PR as the date from first documented CR or PR per RECIST v1.1 to the date of the documentation of disease progression or death due to any cause, whichever is earlier. 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.

Progression Free Survival Rates at 24 weeks is defined as the percentage of participants who achieve PFS at 24 weeks. PFS for a participant is defined as the time from randomization date to the date of first objectively documented disease progression by investigator per response evaluation criteria in solid tumors (RECIST) v1.1 or death due to any cause, whichever occurs first. Based on Kaplan-Meier Estimates. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum during the 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 5 mm.
