PHASE4

Short-term Sintilimab in Combination With Taxane and Carboplatin for Neoadjuvant Therapy in Triple-negative Breast Cancer

Sponsor: Shanghai Jiao Tong University School of Medicine

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to learn about the efficacy and safety of short-term sintilimab in combination with taxane and carboplatin for neoadjuvant therapy in female early-stage triple-negative breast caner patients aging from 18 to 70 years with unilateral and invasive primary lesions above 1cm. The main questions it aims to answer are: 1. Does short-term sintilimab in combination with taxane and carboplatin lead to acceptible pathological complete response (pCR) rates, objective response rates (ORR), event-free survival (EFS) and overall survival (OS)? 2. Does short-term sintilimab in combination with taxane and carboplatin lead to less adverse events than regular-term ICIs reported in literature? Participants will be given 2 cycles of sintilimab, in combination with 4 cycles of taxane and carboplatin before surgery. An optional core-needle biopsy is performed after completing 2 cycles of sintilimab. All participants will be given regular follow-up post surgery according to ASCO guidelines.
