简要总结
The purpose of this study is to evaluate the efficacy and safety of Camrelizumab plus chemotherapy as neoadjuvant therapy and Camrelizumab as adjuvant therapy in participants who have triple negative breast cancer (TNBC).
详细描述
After a screening phase of approximately 28 days, each participant will receive neoadjuvant study treatment (camrelizumab + chemotherapy) for approximately 24 weeks (8 cycles). Each participant will then undergo definitive surgery 2-4 weeks after the last cycle of the neoadjuvant treatment. After definitive surgery, each participant will receive adjuvant study treatment (camrelizumab) for approximately 27 weeks (9 cycles). Following adjuvant study treatment, each participant will be monitored for safety, survival and disease recurrence.
The primary study hypothesis is that camrelizumab is superior to chemotherapy, in combination with chemotherapy, as measured by the rate of Pathological Complete Response (pCR), Event-free Survival (EFS) and Objective Overall Response Rate (ORR) in participants with TNBC.
