药品与企业信息

Dalpiciclib + Aromatase Inhibitor with ctDNA-Guided Therapy药物

其他名称：Dalpiciclib/AI combination therapy、SHR6390 + aromatase inhibitor

Patients receive 4 cycles of neoadjuvant dalpiciclib (125 mg orally, days 1-21 of 28-day cycles) combined with an aromatase inhibitor (letrozole/anastrozole/exemestane). Post-surgery treatment is guided by ctDNA status: （1）ctDNA-negative at baseline and post-neoadjuvant, with post-op Ki67 ≤10% :Continue dalpiciclib + endocrine therapy (ET) for 2 years； （2）ctDNA-positive → negative, or persistently ctDNA-negative with post-op Ki67 \>10% :Randomized 1:1 to: * Arm B1: Dalpiciclib + ET for 2 years. * Arm B2: Adjuvant chemotherapy (investigator's choice) → dalpiciclib + ET for 2 years；（3）Persistently ctDNA-positive or ctDNA-negative → positive: Mandatory adjuvant chemotherapy → dalpiciclib + ET for 2 years. Premenopausal women undergo ovarian suppression with LHRH agonists.

Taxane-Based Neoadjuvant Chemotherapy药物

其他名称：Paclitaxel/cyclophosphamide neoadjuvant therapy、Docetaxel-based chemotherapy regimen

Patients receive 4 cycles of taxane-based neoadjuvant chemotherapy (e.g., paclitaxel 80 mg/m² weekly or docetaxel 75-100 mg/m² triweekly) before surgery. Post-surgery adjuvant chemotherapy (physician's choice) may be administered. This arm serves as the control group for comparing standard chemotherapy efficacy.

研究简介（原文）

* This is a Phase II, multicenter, randomized clinical trial evaluating a ctDNA-guided approach to de-escalate adjuvant chemotherapy in patients with hormone receptor (HR)-positive, HER2-negative early-stage breast cancer. The study aims to determine if combining the CDK4/6 inhibitor Dalpiciclib with endocrine therapy can reduce the need for chemotherapy while maintaining clinical benefits. * Key Details ： 1. Participants: 393 women (aged 18-75) with early-stage HR+/HER2- breast cancer at high risk of recurrence (e.g., tumor size ≥2 cm, lymph node involvement, or high-grade tumors). 2. Design: Patients are randomized 1:4 to two groups: Group A (Chemotherapy) : Receives 4 cycles of taxane-based chemotherapy before surgery. Group B (Experimental) : Receives Dalpiciclib + aromatase inhibitor (AI) for 4 cycles pre-surgery. Post-surgery, treatment is adjusted based on ctDNA results. 3. Primary Goals ： Assess ctDNA clearance rate (conversion from detectable to undetectable ctDNA) after neoadjuvant therapy in Group B. Evaluate 3-year event-free survival (EFS) in Group B (e.g., freedom from cancer recurrence, progression, or death). Secondary Goals ： Safety of Dalpiciclib + endocrine therapy. Tumor response rates (e.g., complete cell cycle arrest, pathological remission). Correlation between ctDNA clearance and long-term outcomes. * Why This Matters ： Current guidelines recommend chemotherapy for high-risk HR+ breast cancer, but it often causes significant side effects. This study explores a personalized approach using ctDNA-a blood-based biomarker-to identify patients who may safely avoid chemotherapy without compromising survival. If successful, it could shift clinical practice toward less toxic, targeted therapies for eligible patients.
