A Clinical Trial Comparing the Efficacy and Safety of Different Doses of BL0175 Injection in Treating Postmenopausal Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Locally Advanced or Metastatic Breast Cancer
The goal of this clinical trial is to compare the objective response rates (ORR) of different doses of BL0175 in patients with postmenopausal hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer. The main questions it aims to answer are: 1. Which dose level of BL0175 demonstrates the optimal ORR? 2. What is the recommended phase 3 dose (RP3D) based on efficacy and safety data across the tested dose levels?
