A Study of WX390 Combined With Toripalimab in Patients With Advanced Solid Tumors

A Phase Ib/IIa Study to Evaluate the Safety and Preliminary Efficacy of WX390 Combined With Toripalimab in Patients With Advanced Solid Tumors

The goal of this clinical trial is to evaluate the safety and preliminary efficacy of WX390 combined with Toripalimab in patients with advanced solid tumors. The main questions it aims to answer are:

• the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of WX390;
• safety and preliminary in combined therapy. Participants will be treated with WX390 orally and Toripalimab intravenously, and follow the efficacy and safety evaluation according to the protocol.

This study will be an open-label, multicenter phase Ib/IIa clinical trial. After being informed about the study and potential risks, all patients giving written informed consent will undergo a 4-week screening period to determine eligibility for study entry. And then patents will be administered for 8 cycles treatment and 8 weeks safety follow up after the last dose of treatment. The efficacy and safety measures will be conducted and collected every cycle.
