ER+/HER2- Breast Cancer

A Phase I/II, Open-label study to assess the safety, tolerability, pharmacokinetic, and antitumor efficacy of FWD1802 monotherapy in patients with ER+/HER2- unresectable locally advanced or metastatic breast cancer. This clinical trial aims to explore the role of FWD1802 in the ER+/HER2- advanced breast cancer patient population. The primary objectives are to address the following questions: Phase I Study: Determine the Recommended Phase II Dose (RP2D) and/or Maximum Tolerated Dose (MTD) of FWD1802 in patients with ER-positive, HER2-negative locally advanced or metastatic breast cancer. Phase II Study: To evaluate the efficacy of FWD1802 at the RP2D in patients with ESR1-mutated ER-positive/HER2-negative locally advanced or metastatic breast cancer, using objective response rate (ORR) as the efficacy endpoint.

This study aimed to evaluate the efficacy and safety of SKB264 combined with KL-A167 as neoadjuvant therapy in early-stage high-risk ER+HER2- breast cancer patients.

The purpose of this study is to evaluate the efficacy and safety of high-intensity focused ultrasound (HIFU) combined with toripalimab plus chemotherapy versus chemotherapy as neoadjuvant therapy for ER+/HER2- breast cancer.
