A Study of Immunotherapy Combined With Neoadjuvant Therapy Versus Neoadjuvant Therapy for Breast Cancer

Phase 2

• Conditions: Stage II-III Breast Cancer
• Interventions: Drug: cytotoxic chemotherapy (docetaxel or epirubicin or cyclophosphamide or carboplatin); Drug: anti-Her2 monoclonal antibody (Trastuzumab, Pertuzumab); Drug: traditional herbal medicine

• Registration Number: NCT05483439
• Lead Sponsor: Shengjing Hospital

Brief Summary

This is a randomized, open label Phase II neoadjuvant study comparing the efficacy and safety of the combination of traditional herbal medicine for cancer immunotherapy and neoadjuvant therapy versus neoadjuvant therapy in patients with breast cancer.

Detailed Description

This is a randomized, open label Phase II neoadjuvant study comparing the efficacy and safety of the combination of traditional herbal medicine for cancer immunotherapy and neoadjuvant therapy versus neoadjuvant therapy in patients with breast cancer. Patients will be randomized (1:1) to one of the two treatment arms: arm 1, combination of traditional herbal medicine for cancer immunotherapy and neoadjuvant therapy for 6 or 8 cycles; arm 2, neoadjuvant therapy 6 or 8 cycles. Patients will undergo surgery after neoadjuvant therapy. Efficacy will be assessed every 2 cycles.

Arm && Interventions

Group	Intervention	Description
Immunotherapy and neoadjuvant therapy	cytotoxic chemotherapy (docetaxel or epirubicin or cyclophosphamide or carboplatin)	Traditional herbal medicine twice daily combined with neoadjuvant therapy recommended by the guidelines every 3 weeks, for 6 or 8 cycles.
Immunotherapy and neoadjuvant therapy	anti-Her2 monoclonal antibody (Trastuzumab, Pertuzumab)	Traditional herbal medicine twice daily combined with neoadjuvant therapy recommended by the guidelines every 3 weeks, for 6 or 8 cycles.
Immunotherapy and neoadjuvant therapy	traditional herbal medicine	Traditional herbal medicine twice daily combined with neoadjuvant therapy recommended by the guidelines every 3 weeks, for 6 or 8 cycles.
neoadjuvant therapy	cytotoxic chemotherapy (docetaxel or epirubicin or cyclophosphamide or carboplatin)	Only received neoadjuvant therapy recommended by the guidelines every 3 weeks, for 6 or 8 cycles.
neoadjuvant therapy	anti-Her2 monoclonal antibody (Trastuzumab, Pertuzumab)	Only received neoadjuvant therapy recommended by the guidelines every 3 weeks, for 6 or 8 cycles.

Primary Outcome Measures

Name	Time	Method
Total pathological complete response rate (tpCR)	One month after surgery	The disappearance of all invasive tumours in the breast and axillary lymph nodes

Secondary Outcome Measures

Name	Time	Method
Adverse events (AE) and serious adverse events (SAE)	Period of neoadjuvant therapy (treatment 1-6 months)	For adverse events (AE) and serious adverse events (SAE), refer to NCI-CTC AE 5.0 standard.
Disease free survival (DFS)	5 years	Disease-free survival (DFS) is the time from the day of enrollment to the first occurrence of recurrent disease, including second primary malignancies in the non-breast area and breast ductal carcinoma in situ.
Five-year overall survival (OS)	5 years	Five-year overall survival (OS) is the time from the random date to death due to any cause.
Expression of immune cells	One month after surgery	Expression of immune cells (T cell, B cell, NK cell )
Expression of cytokines (IL, INF-r, TNF-a)	One month after surgery	Expression of cytokines (IL, INF-r, TNF-a)
Global health status and functioning subscales	One month after surgery	Health-related quality of life (HRQoL) was measured using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30; version 3).
Cancer-related fatigue scores	One month after surgery	Piper Fatigue Scale will be used to measure cancer-related fatigue. The scale scores were measured：at baseline, at the end of cycles 2 and 4, and before surgery. Each score represents the degree of fatigue: a score of 0 means none, 1-3 means mild, 4-6 means moderate, 7-10 means severe.
