What this trial studies

This phase II clinical trial aims to assess the efficacy and safety of a new treatment regimen that combines Chidamide with Zimberelimab in patients with metastatic triple-negative breast cancer who have already undergone second-line therapy. The study will recruit 47 participants and will be conducted at a single center. Participants will be evaluated based on their measurable lesions and overall health status, ensuring they meet specific inclusion criteria while excluding those with certain medical conditions.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with histologically confirmed metastatic triple-negative breast cancer who have failed previous anti-tumor treatments.

Not a fit: Patients who are pregnant, have uncontrolled medical problems, or have severe hypersensitivity to the study drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with metastatic triple-negative breast cancer who have limited treatment alternatives.

How similar studies have performed: While the combination of Chidamide and Zimberelimab is a novel approach, similar studies exploring combination therapies in triple-negative breast cancer have shown promising results.
