Descriptive Information
Brief Title Targeted Next Generation Sequencing for the Efficacy of Trastuzumab Neoadjuvant Chemotherapy in Breast Cancer
Official Title An Observational Phase II Trial of Targeted Next Generation Sequencing Analysis for the Efficacy of Trastuzumab Neoadjuvant Chemotherapy in Patients With HER2 Positive Breast Cancer
Brief Summary To explore the genetic background of patients with HER2 positive breast cancer that benefit from trastuzumab combined with neoadjuvant chemotherapy, identify clinically actionable mutations that associated with trastuzumab resistance or drug efficacy, we designed this Observational phase II trial. The primary endpoint is genetic profile of HER2+ breast cancer patients treated with trastuzumab combined neoadjuvant chemotherapy. Secondary endpoints included pathological complete response (pCR) rate and safety.
Detailed Description

Currently, patients with stage II-III breast cancer still accounts for a large population in China, and neoadjuvant therapy is considered the standard treatment for them. The pathological complete response (pCR) rate takes for an indicator for regimens efficacy, and the achievement of pCR after neoadjuvant chemotherapy is associated with favorable outcomes including disease-free survival and overall survival.

HER2+ breast cancer represents an invasive and poor prognosis subtype, and the efficacy of neoadjuvant therapy for these patients has been greatly augmented by the addition of trastuzumab. However, more than 50% of HER2+ breast cancer patients treated with trastuzumab combined neoadjuvant chemotherapy cannot achieve pCR, even experience primary drug resistance and rapid disease progression. Therefore, to explore the genomic features of the population that benefited from trastuzumab combined with chemotherapy is of great significance for personalized treatment of HER2+ breast cancer, aiming to avoid overtreatment and identify clinically actionable mutations for future therapy instructions.

Study Type Observational
Study Design Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration Not Provided
Biospecimen Retention:   Samples With DNA
Description:
Samples retained, with potential for extraction of DNA from at least one of the types of samples retained (tissue, whole blood)
Sampling Method Probability Sample
Study Population 100
Condition
  • Observational
  • Prospective
Intervention Drug: Trastuzumab+TP
Trastuzumab (4 mg/kg loading dose, then 2 mg/kg I.V., every week, totally 17 weeks (6 cycles)) combined with TC neoadjuvant chemotherapy (Docetaxel 75 mg/m2 I.V., day 1, Carboplatin 400 mg/kg, I.V., day 2, every 3 weeks, totally 6 cycles).
Other Name: Trastuzumab+Docetaxel+Carboplatin
Study Groups/Cohorts Trastuzumab+TP neoadjuvant chemotherapy
100 cases of patients with stage II-III HER2+ breast cancer will be assigned participants to neoadjuvant treatment regimen, including Trastuzumab combined with Docetaxel and Carboplatin. 5-10 ml peripheral blood will be collected from each patient and formalin fixed paraffin embedded (FFPE) blocks/sections or fresh tumor tissues/biopsies will be obtained from the hospitals before and after neoadjuvant therapy. The genomic characteristics between patients achieved pCR and non-pCR will be analyzed. The clinically actionable mutations for future therapy instructions will be identified.
Intervention: Drug: Trastuzumab+TP
