About

This study is a one-arm, open, multicenter phase 1b/2 clinical trial of YL-13027 combined with Sintilimab in patients with Advanced Solid Tumors, aiming at exploring the MTD and RP2D and observing the preliminary efficacy.The trial can be divided into two parts: dose escalation part and expansion part.Sintilimab is administered as a fixed-dose intravenous injection(200mgQ3w）.

Full description

Part 1 (Phase Ib):

This is a dose escalation,3+3 design study, to evaluate the safety and tolerability, and to determine the RP2D of YL-13027 when administered b.i.d. in patients with advanced solid tumors. One cycle is 21 days.

Part 2 (Phase II):

This is an expansion phase in patients with advantage advanced solid tumors to further evaluate the safety, tolerability and preliminary anti-tumor activity of YL-13027 at the RP2D combined with Sintilimab.

Enrollment: 49 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
