This is an open-label phase 1 study with expansion. The study will start with a dose escalation of single-agent ABSK061 administered in repeated 28-day cycles in patients with advanced solid tumors to evaluate safety and tolerability. The expansion part will investigate oral ABSK061 at the recommended dose for expansion (RDE) to further evaluate safety and tolerability among selected tumor types. Preliminary antitumor activity will also be assessed.
Patient should understand, sign, and date the written informed consent form prior to screening.
