Summary

Iparomlimab and Tuvonralimab Injection (QL1706) is a bifunctional combination antibody targeting both programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4). This is a prospective clinical study that plans to enroll screened, eligible early-stage breast-cancer patients to receive neoadjuvant QL1706 plus chemotherapy (four cycles of TP ± four cycles of AC). After the four TP cycles, imaging and core biopsy will be performed. Patients who achieve radiologic complete response will proceed directly to surgery; those who do not will receive four additional AC cycles before surgery. A key feature is the incorporation of an response-guided neoadjuvant therapy（RGN）model to identify sensitive patients who can forgo anthracyclines, thereby reducing long-term cardiotoxicity.

Conditions

• Breast Cancer
• Neoadjuvant Therapy
• Immune Checkpoint Inhibitors
• QL1706

Interventions

Type	Name	Description
DRUG	QL1706 combined with Chemotherapy	Participants receive QL1706 every 3 weeks (Q3W) + Albumin-bound paclitaxel every 3 weeks (Q3W) + Cisplatin (Q3W) x 4 cycles. After the four TP cycles, imaging and core biopsy will be performed. Patients who achieve radiologic complete response will proceed directly to surgery; those who do not will receive QL1706 Q3W + epirubicin Q3W + cyclophosphamide Q3W x 4 cycles as neoadjuvant therapy before surgery.
