Chidamide Combined With Cisplatin for Relapsed or Metastatic Triple-negative Breast Cancer

The goal of this clinical trial is to evaluate therapeutic efficacy and safety of Chidamide combined with Cisplatin for relapsed or metastatic triple-negative breast cancer.

Study Overview

• Status: Recruiting
• Conditions: Triple-negative Breast Cancer
• Intervention / Treatment: Drug: Chidamide combined with Cisplatin

Detailed Description

Triple-negative breast cancer (TNBC), the most difficult-to-treat breast cancer subtype, lacks well-defined treatment options. This is a prospective, single-center, one-arm, open-label, phase II clinical trial evaluating the efficacy and safety of chidamide in combination with cisplatin in subjects with relapsed or metastatic triple-negative breast cancer.
