Symbiotic-GI-13: A Study to Learn About Study Medicine Called PF-08634404 as a Single Treatment and Combination Treatment in Adult Participants With a Liver Cancer Called Hepatocellular Carcinoma, That is Too Advanced to be Removed by Surgery and May Have Spread to Other Parts of the Body.
Sponsor: Pfizer
ClinicalTrials ID:NCT07227012
This study evaluates PF-08634404, alone or with ipilimumab, in adults with advanced hepatocellular carcinoma. Eligible participants must be 18+, have untreated, measurable HCC, and meet specific health criteria. Treatments are administered via IV infusion at clinical sites, with medical monitoring throughout.

Program Overview
The purpose of this study is to learn about the effects of study medicine (PF-08634404) when given alone or with another antibody (ipilimumab) for the treatment of a type of liver cancer called hepatocellular carcinoma (HCC) that is either locally advanced (spread to nearby tissues) or has spread to other parts of the body.
To join the study, participants must meet the following conditions:
- Be 18 years or older.
- Have locally advanced or metastatic HCC.
- Is not a candidate for complete surgical or loco-regional therapies.
- Have not received any whole-body treatment for HCC.
Participants will receive PF-08634404 either alone or in combination with ipilimumab. The medicine will be given through intravenous (IV) infusions, which means it will be administered directly into a vein. All treatments will take place at clinical trial sites, where trained medical staff will monitor participants during and after each visit.
