The Efficacy and Safety of Sintilimab Plus Anlotinib Combined With Chemotherapy as Neoadjuvant Therapy in TNBC

• Status: Recruiting
• Trial end date: 2024-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

The purpose of this study is to evaluate the efficacy and safety of Sintilimab plus anlotinib combined with chemotherapy as neoadjuvant therapy in participants who have triple negative breast cancer (TNBC). After a screening phase of approximately 28 days, each participant will receive neoadjuvant study treatment (Sintilimab + anlotinib + chemotherapy) based on schedule for approximately 24 weeks (8 cycles). Each participant will then undergo definitive surgery 4-6 weeks after conclusion of the last cycle of the neoadjuvant study treatment. Following adjuvant study treatment, each participant will be monitored for safety, survival and disease recurrence. The primary outcome measure is pathological complete response (pCR) rate using the definition of ypT0/Tis ypN0.
