Summary

Treatment of triple-negative breast cancer (TNBC) remains a significant challenge. Although immune checkpoint inhibitors combined with chemotherapy have achieved breakthroughs, drug resistance persists, leaving clinical needs unmet. Bisphosphonates target the FDPS/mevalonate pathway, not only directly inhibiting tumors but also remodeling the immune microenvironment, positioning them as a potential strategy to reverse immune resistance. Therefore, this exploratory study of camrelizumab combined with risedronate sodium and chemotherapy aims to generate synergistic anti-tumor effects through the dual action of immune checkpoint blockade and metabolic-immune microenvironment remodeling. The goal is to overcome resistance, improve the objective response rate, and ultimately enhance the long-term survival prognosis for patients with TNBC.

Conditions

  • Breast Cancer Triple Negative Breast Cancer

Interventions

DRUG

Camrelizumab + Risedronate Sodium + Chemotherapy

Camrelizumab: 200 mg, intravenous drip, administered in line with the chemotherapy regimen cycles. Risedronate Sodium: Oral administration. Should be taken while in an upright position at least 30 minutes before the first food or drink of the day, swallowed with a full glass of plain water (approximately 200 ml). Patients should not lie down for at least 30 minutes after taking. Dosage is one 5 mg tablet once daily. Chemotherapy regimens are selected by the physician and include, but are not limited to: TAC, TP-AC, AC-T, etc. A total of 6 treatment cycles are planned; the subsequent regimen will be chosen by the investigator.
