A Randomized, Double-blind, Multi-center, Phase 2 Study to Assess the Efficacy and Safety of ABSK-011 Plus Best Supportive Care (BSC) vs. Placebo Plus BSC in Previously Systemically Treated Advanced or Unresectable Hepatocellular Carcinoma Patients With FGF19 Overexpression

Overview
Brief Summary
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.

ABSK-011 plus BSC
Intervention: ABSK-011+BSC (Drug)
Control arm
Placebo plus BSC
Intervention: Placebo+BSC (Drug)
Outcomes
Primary Outcomes
ORR by BICR
Time Frame: through study completion, up to 2 years
Objective response rate (ORR) assessed by Blinded Independent Central Review (BICR) per RECIST v1.1, defined as the proportion of patients achieving complete response (CR) or partial response (PR). Patients who receive crossover treatment or start a new anti-tumor therapy prior to achieve an objective response (PR or CR) will be considered as non-responders.
Secondary Outcomes
- PFS(through study completion, , up to 2 years)
- DOR(through study completion, up to 2 years)
- DCR(through study completion, up to 2 years)
- TTP(through study completion, up to 2 years)
- TTR(through study completion, up to 2 years)
- OS(through study completion, up to 2 years)
- ORR by investigator(through study completion, up to 2 years)
- Adverse events(through study completion, up to 2 years)
