Study of BAY 3547926 for Advanced Liver Cancer

This study is looking at a new drug, BAY 3547926, for people with advanced hepatocellular carcinoma (HCC), a type of liver cancer. Researchers want to understand how safe BAY 3547926 is and how well it works. The drug delivers a radioactive agent that targets and damages cancer cells, aiming to cause little harm to healthy tissues. This is the first time BAY 3547926 is being tested in humans. The study will also help determine the best dose of BAY 3547926 and how your body processes it. You may be eligible if you have advanced HCC that has a special protein called Glypican 3 (GPC3).

Study design
This is a first-in-human study with a planned enrollment of 148 participants. It will first find a safe dose (Part 1) and then expand to further test that dose (Part 2).
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 60 months (5 years) after their first administration of the study drug to monitor for side effects.

Eligibility criteria

Inclusion
