ABSK-011+BSC vs. Placebo+BSC in Previously Treated Advanced HCC With FGF19 Overexpression

This is a randomized, double-blind, multicenter, Phase 2 study to evaluate the efficacy and safety of ABSK-011 plus BSC versus placebo plus BSC in advanced or unresectable hepatocellular carcinoma (HCC) patients with FGF19 overexpression who have received prior systemic therapy. Approximately 141 advanced or unresectable HCC patients with FGF19 overexpression who have received prior systemic therapy will be enrolled and randomized to experimental arm or control arm in a 2:1 ratio. Patients will receive assigned study treatment, every 28-day treatment cycle within 1 day of randomization until disease progression, intolerable toxicity, start of new anti-tumor therapy, death, patient refuse to continue treatment, loss to follow-up, or other reasons leading to treatment discontinuation. Immediate BICR review is required for patients with radiographic disease progression as assessed by the investigator. If disease progression is assessed by BICR, the investigator is allowed to unblind after disease progression according to the protocol-specified procedures. After unblinding, patients in the experimental arm, study drug should be discontinued. Patients in the control arm may be transferred to receive ABSK-011 plus BSC after assessment.
