Phase 2 Interventional Akeso · NCT05227664

This study is testing if a new combination of drugs, AK117 and AK112, can help people with advanced triple-negative breast cancer when used with chemotherapy.

What this trial studies

This Phase II trial aims to assess the efficacy, safety, and pharmacokinetics of AK117 and AK112 when combined with chemotherapy in patients with locally advanced or metastatic triple-negative breast cancer (TNBC) who have not previously received systemic therapy for their condition. Participants will receive either Nab paclitaxel or paclitaxel alongside the investigational drugs. The study will focus on patients with documented TNBC characterized by the absence of HER2, ER, and PR expression.

Who should consider this trial

Good fit: Ideal candidates are individuals with metastatic or locally advanced TNBC who have not undergone prior chemotherapy or targeted therapy.

Not a fit: Patients with known central nervous system disease or those who have received prior systemic therapy for their condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced triple-negative breast cancer.

How similar studies have performed: While this approach is being explored in this specific context, similar studies have shown promise in treating triple-negative breast cancer with novel agents.
