The goal of this clinical trial is to learn if drug AST-3424 works to treat AKR1C3 high expressing advanced hepatocellular carcinoma after failure of systemic therapy with immune checkpoint inhibitors. The main question it aims to answer is:
Does AST-3424 prolong survival in patients with AKR1C3-high Expressing advanced Hepatocellular Carcinoma who have progressed after immune checkpoint inhibitors based therapies?
Researchers will compare AST-3424 to regorafenib (current optional therapy for target patients) to see if AST-3424 works.
Participants will:
Receive AST-3424 infusion on Day 1 and Day 8 of each 21-day treatment cycle or take regorafenib once a day on Day 1 -Day 21 of each 28-day treatment cycle.
