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

higher)

infection or active tuberculosis. Positive tests for hepatitis B virus surface antigen
(HBsAg), or antibody to hepatitis B core Ag or hepatitis C RNA in serum. (subjects
with history of hepatitis C infection but negative hepatitis C virus polymerase chain
reaction (PCR) test and subjects with hepatitis B with positive hepatitis B surface
antibody are allowed)
18. Patients with refractory/uncontrolled ascites or pleural effusion. Patients with
indwelling catheters are allowed.
19. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a
female after conception and until the termination of gestation, confirmed by a
positive human chorionic gonadotropin (hCG) laboratory test within 7 days prior to the
start of study drug.
20. Non-surgically sterilized male or female patients of childbearing potential must agree
to use effective methods of birth control during the study and for up to 6 months
after the last dose of study drug.
21. Sexually active males unless they use a condom during intercourse while taking drug
and for 5 compound half-lives plus 60 days after stopping study drug and should not
father a child in this period. A condom is required to be used also by vasectomized
men in order to prevent delivery of the drug via seminal fluid.
22. Any other clinically significant comorbidities, such as uncontrolled pulmonary
disease, active infection, or any other condition, which in the judgment of the
Investigator, could compromise compliance with the protocol, interfere with the
interpretation of study results, or predispose the patient to safety risks.
