Conditions

Advanced or unresectable Hepatocellular Carcinoma (HCC)

Brief summary

The main goal of phase 1 will check and count for how many people have problems or serious problems from the medicine, if anyone must stop taking it because of these problems, and if any problems cause death., The main goal of phase 2 will be to check and count how many people's liver cancer gets much smaller or completely goes away with the treatment (OR (Objective Response) confirmed CR (complete response) or PR (partial response)).

Detailed description

To check how many people’s liver cancer gets much smaller or goes away (cancer shrinkage)., To count how many people have problems or serious problems from the medicines, including those who stop treatment or die because of them (safety), To measure how much pumitamig is in the blood after treatment and before the next dose (pumitamig levels)., To measure how much ipilimumab is in the blood before the next dose (ipilimumab levels)., To see if people’s bodies make fighters against the medicines (anti-drug antibodies)., To see how long people live without the cancer getting worse, and how long the cancer stays smaller or goes away (progression delay (PFS, Progression-Free Survival and duration (DOR, Duration of Response).
