Intervention model description: Absk-011 combined with atelizumab in the treatment of patients with advanced or unresectable HCC
Primary purpose: TREATMENT

Brief summary: This study is an open phase II clinical study, which consists of part a and Part B. Part a will evaluate the safety and tolerability of absk-011 combined with atilizumab in patients with advanced or unresectable HCC to And pk/pd characteristics, and determine the treatment plan of Part B. Part B will evaluate absk-011 combined with atilizumab Anti Fgf19 overexpression in advanced stage or non resectable patients who have not received systemic therapy or only received first-line systemic therapy before In addition to the safety and tolerability of HCC subjects, the antitumor activity of the combination will be further evaluated.

Detailed description: During part a, all subjects will receive continuous oral administration of absk-011 once a day (QD) or twice a day (bid) with an initial dose of 180 mg, and intravenous infusion (IV) of 1200 mg of atilizumab every 21 days (q3w). After the first subject (sentinel subject) in each dose cohort completed the first combined medication, follow-up subjects were administered at least 7 days later.

Part B will include subjects with advanced unresectable HCC who have not previously received systemic therapy or only received first-line systemic therapy and whose Fgf19 expression is positive. No more than 70% of the enrolled subjects have only received first-line systemic therapy

2. there is no limit on gender, and the age when signing the informed consent is ≥ 18 years old.
3. part a: subjects with advanced or unresectable HCC who must be confirmed by histology, cytology or imaging, are not suitable for curative surgery and / or local treatment, have disease progression or cannot tolerate standard treatment after standard treatment, and have no standard treatment due to physical conditions or disease status (according to local / regional guidelines), and the child Pugh score is 5-6.

Part b: subjects with advanced or unresectable HCC who must be confirmed histologically or cytologically, are not suitable for curative surgery and / or local regional treatment, and have not previously received systematic treatment or only received first-line systematic treatment-
