Neoadjuvant Therapy Combined With Trastuzumab Rezetecan and Toripalimab for HR+/HER2-low Breast Cancer (NEOTORCH-BREAST 08)

This study is a prospective, multi-cohort, multicenter, open-label exploratory clinical trial. The primary study objective is to evaluate the pathologic complete response (PCR) of treatment of HR+/HER2-low breast cancer with neoadjuvant therapy combined with Trastuzumab Rezetecan and Toripalimab , including the incidences and types of adverse events. The secondary endpoints include event-free survival (EFS), residual cancer burden (RCB), and objective response rate (ORR).

Chemotherapy With or Without Adebrelimab and T-DXh as Neoadjuvant Therapy for HR+/HER2 Low Early Stage Breast Cancer

The goal of this clinical trial is to learn if add SHR-A1811 and/or Adebrelimab on standard chemotherapy could further improve the pCR rate in HR+/HER2 low early stage breast cancer patients. It will also learn about the safety of these combination regimen. The main questions it aims to answer are: Is Adebrelimab plus chemotherapy better than T-EC chemotherapy alone in neoadjuvant setting of HR+/HER2-low early stage population? Is SHR-A1811-EC plus Adebrelimab better than T-EC chemotherapy and/or Adebrelimab plus chemotherapy Participants will: Take 8 cycles of standard chemotherapy at day1, every 3 weeks cycle(standard care), or take 8 cycles of adebrelimab plus standard chemotherapy at day 1, every 3 weeks cycle(experimental 2), or take 4 cycles of SHR-A1811 and Adebrelimab at day 1, every 3 weeks cycle, then 4 cycles of adebrelimab plus EC chemotherapy at day 1, every 3 weeks cycke(experimental 1). Visit the clinic once every 6 weeks at neoadjuvant period for tumor assessment. Take surgery after completion of 8 cycles of neoadjuvant therapy and assess the pathological response. Then, visit the clinic once every 12 weeks at first year and then every 6 months for tumor assessment.

SHR-A1811 Alone or in Combination With Adebrelimab as Neoadjuvant Treatment in HR Positive/HER2 Low Breast Cancer

This is an open-label, phase II study evaluating the efficacy and safety of SHR-A1811 alone or in combination with Adebrelimab in Stage II-III HR Positive/HER2 Low Breast Cancer. Subjects will receive the neoadjuvant therapy of SHR-A1811 alone or in combination with Adebrelimab for six cycles, and then undergo surgery within 4 weeks after neoadjuvant therapy. Efficacy will be assessed every 2 cycles.
