Description of intervention(s) / exposure
Treatment: Drugs - ABSK043 oral capsule

Experimental: ABSK043 - Dose escalation of oral ABSK043 with a starting dose of 200mg once daily will be guided by"BOIN" escalation rules based on safety data until an MTD has been identified or a RDE. For each dose,In the escalation part, sequential cohorts of patients will receive an oral dose of ABSK043 in repeated 28-day cycles. Starting dose level will be 200 mg QD. Cohort 3 on 800mg will be switched to 400mg BID.Then, patients will continuously receive ABSK043 (total daily dose) in repeated 28-day cycles.For the Dose Expansion Phase, patients will each receive orally administered doses of ABSK043 at the RDE in repeated 28-day cycles.


Treatment: Drugs: ABSK043 oral capsule
ABSK043 is a novel, oral small molecule inhibitor of PD-L1

antibody are allowed)

18. Patients with refractory/uncontrolled ascites or pleural effusion. Patients with
indwelling catheters are allowed.
