This study consists of two parts. Part 1 is a dose-escalation/safety evaluation to provisionally identify a dose and regimen of SY-1365 for further evaluation in Part 2. Following the identification of a recommended dose and regimen from Part 1, the study entered Part 2 to further evaluate safety and the antitumor activity of SY-1365 in patients with select solid tumors, and to confirm target engagement and downstream pathway impact in patients with any solid tumor histology.
