Precise Treatment for BLIS Subtype of TNBC in the First-line Treatment of Locally Advanced or Metastatic Breast Cancer

Summary

The study is being conducted to evaluate VEGFR BP102 with nab-paclitaxe or treatment of physician's choice (TPC) versus nab-paclitaxe or TPC in patients for basal-like immune suppressed (BLIS) subtype of triple-negative breast cancer (TNBC) in the first-line teatment of unresectable locally advanced or metastatic TNBC.
