A Phase 2 Clinical Study of ABSK061 and ABSK043

ABSK061 is a selective and potent pan FGFR 2/3 inhibitor with demonstrated clinical activity in participants with a variety of FGFR inhibitors in a variety of solid tumors. ABSK043 is a small molecule PD-L1 inhibitor with good oral bioavailability, high selectivity and high activity, and is currently being developed for the treatment of multiple cancers and potential non-oncology indications. This study targets the underlying altered biology of FGFR-driven tumors irrespective of solid tumor histology subtype. The study consists of screening phase, treatment phase and the post treatment follow-up phase (from the end of treatment visit until the participant has died, withdraws consent, is lost to follow-up, or the end of study, whichever comes first). End of study is considered of the last visit of the last patient in this trial or the procedures shown in the schedule, or 12 months after the first dose of the last enrolled patient, whichever occurs first.
