简要总结
To explore the application of Camrelizumab with chemotherapy as neoadjuvant treatment of early-stage TNBC. Phase II clinical study of Camrelizumab in neoadjuvant treatment of early-stage TNBC is proposed. The study aims to evaluate the efficacy and safety of Camrelizumab and to provide a new treatment option for neoadjuvant treatment of early-stage TNBC.
详细描述
This study is a single center, non blinded, randomized phase II clinical trial. A total of 40 patients early-stage T3-4NanyM0 any TanyN+M0 TNBC, who meet the inclusion and exclusion criteria, are planned to be enrolled.
Patients will receive neoadjuvant chemotherapy as 4 course ddAC (doxorubicin 60 mg/m² as an and cyclophosphamide 600 mg/m² on day 1 every 2 weeks) + paclitaxel 80 mg/m² + carboplatin AUC2 on day 1 every 1 weeks a total of 12 weeks with camrelizumab at a dose of 200 mg once every 2 weeks for a total of 16 weeks.
Imaging assessments will be conducted every 4 weeks during the neoadjuvant treatment phase. After the neoadjuvant treatment is completed, surgery will be performed within 4 weeks of the last study drug administration. Whether to receive adjuvant treatment after surgery will be determined by the investigator. The primary endpoint of the study is the pathological complete response (pCR) rate. Secondary endpoints include objective response rate (ORR), event-free survival (EFS), overall survival (OS), and safety. During the follow-up phase, survival follow-up will be conducted every 3 months (±28 days) in the first year and every 6 months (±28 days) thereafter, until disease progression, disease recurrence, or until 3 years after the last patient is enrolled (whichever occurs first).

结局指标
主要结局
Pathologic Complete Response (pCR)
时间窗: The outcome was changed from 19 weeks at the time of results entry as the treatment period was actually 20 weeks and the outcome was assessed 4-6 weeks after treatment when surgery took place.
Pathologic response will be assessed in the surgically resected cancer and lymph nodes after completion of all chemotherapy by the local pathologist as part of routine care. Pathologic complete response is defined as no invasive cancer in the resected breast tissue and lymph nodes (ypT0/Tis, ypN0).
次要结局
- objective response rate (ORR)(average 18 months)
- Disease-free Survival(expected average 48 months)
- Overall Survival(approximately 48 months)
