Guided chemotherapy for HER2-negative early breast cancer using drug screening

Neoadjuvant Therapy Study Guided by Drug Screening in Vitro Patient-derived Tumor-like Cell Clusters for Human Epidermal Growth Factor Receptor 2 (HER2) Negative Early Breast Cancer Patients

Phase1; Phase2 Interventional Peking University People's Hospital · NCT04836156

This study is testing a new way to choose the best chemotherapy drugs for people with early HER2-negative breast cancer by using lab tests on their tumor cells before treatment starts.

What this trial studies

This study investigates the use of in vitro drug sensitivity screening to guide neoadjuvant chemotherapy for patients with HER2-negative early breast cancer. By utilizing a novel patient-derived tumor-like cell cluster technology, the study aims to identify which chemotherapy drugs are most effective for individual patients before treatment begins. A total of 46 participants will undergo this screening to tailor their chemotherapy regimen, potentially improving treatment outcomes and reducing unnecessary side effects. The study builds on preliminary findings that suggest a strong correlation between in vitro drug sensitivity and clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with invasive HER2-negative early breast cancer who are either T2 or node positive and have an ECOG performance status of 0-1.

Not a fit: Patients with stage IV breast cancer, inflammatory breast cancer, or severe chronic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective chemotherapy treatments for patients with HER2-negative early breast cancer.

How similar studies have performed: Preliminary studies using similar in vitro drug sensitivity screening methods have shown promising results, indicating potential for success in this approach.
