A Phase 1 Study of CX1003 (Kanitinib) in Patients with Advanced Solid Tumors

Summary

CX1003 is a novel multi-target tyrosine kinase inhibitor that is designed to primarily inhibit vascular endothelial growth factor receptor 2 (VEGFR2) and hepatocyte growth factor receptor (HGFR/MET). This study aimed to evaluate the safety, pharmacokinetics, and antitumor activity of CX1003 in patients with refractory advanced or metastatic solid tumors.
