About

This study is a phase Ia study of single drug BR101 for Advanced solid tumor. The main purpose of this study is to Evaluate the safety and tolerability of BR101monotherapy (single dose and multiple doses) in Subjects with Advanced Solid Tumors and determine the MTD if possible, and determine the RP2D.

The secondary purpose of this study is to explore the Pharmacokinetics, Immunogenicity, Antitumor Activity of BR101 monotherapy (single dose and multiple doses) in Subjects with Advanced Solid Tumors
