Study summary

Hepatocellular carcinoma (HCC) is a common cancer worldwide and a leading cause of cancer-related death. The majority of participants first presenting with HCC have advanced unresectable or metastatic disease. The purpose of this study is to evaluate the optimized dose, adverse events, and efficacy of livmoniplimab in combination with budigalimab.

Livmoniplimab is an investigational drug being developed for the treatment of HCC. There are 3 treatment arms in this study and participants will be randomized in a 1:1:1 ratio. Participants will either receive livmoniplimab (at different doses) in combination with budigalimab (another investigational drug), lenvatinib, or sorafenib. Approximately 120 adult participants will be enrolled in the study across 60 sites worldwide.

In arm 1 (control), participants will receive the investigator's choice: lenvatinib as an oral capsule or sorafenib as an oral tablet, once daily. In arm 2, participants will receive intravenously (IV) infused livmoniplimab (dose A) in combination with IV infused budigalimab, every 3 weeks. In arm 3, participants will receive intravenously (IV) infused livmoniplimab (dose B) in combination with IV infused budigalimab, every 3 weeks. The estimated duration of the study is up to 2 years

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, questionnaires, and scans.
