Study Description

Brief Summary

This is a first-in-human study with the SYHX2005 tablet primarily designed to evaluate the safety and tolerability of SYHX2005 at increasing doses in patients with advanced solid tumors and for whom no standard of care exists. The study will be conducted in two parts: Stage1 dose-escalation and Stage2 dose-expansion. In Stage1, patient enrolment will be proceeded according to a "Accelerated Titration + BOIN" design in order to identify the maximum-tolerated dose (MTD) or recommended dose. In Stage2, preliminary efficacy response will be assessed in patients with advanced solid tumors in use of the recommended dose.

Arms and Interventions

Arm Intervention/Treatment
Experimental: SYHX2005

Stage1 dose-escalation: Patients with advanced solid tumors will receive escalating doses of SYHX2005 as monotherapy. Stage2 dose-expansion: Patients with advanced solid tumors will receive SYHX2005 monotherapy at recommended dose (1 or 2 ) in Stage 1 (dose escalation) to evaluate the preliminary antitumor activity of SYHX2005.

Drug: SYHX2005
Tablets. Take orally.
