Neoadjuvant Chemotherapy Combined With Toripalimab for TNBC (NEOTORCH-BREAST02)

Официальное название

Neoadjuvant Chemotherapy Combined With Toripalimab for Triple-negative Breast Cancer : a Prospective, Single-arm, Multi-center Study (NEOTORCH-BREAST02)

Обзор

This study is a prospective, single arm, multi-center phase II clinical trial. The primary study objective is to evaluate the pathologic complete response（PCR） of Adjuvant treatment of TNBC breast cancer with Toripalimab combined with neoadjuvant chemotherapy, including the incidences and types of adverse events. The secondary study objective is to observe and evaluate the disease-free survival (DFS), Progression-Free-Survival (PFS ),and Objective Response Rate(ORR)

Критерии участия

Критерии включения
