Identifying biomarkers for treatment response in triple negative breast cancer

Identification of Predictive Biomarkers of Response to Chemotherapy and Immune Checkpoint Inhibitors in Early Triple Negative Breast Cancer: an Integrative Multiomics Platform

Observational Vall d'Hebron Institute of Oncology · NCT05916755

This study is testing if certain biological markers in tissue samples can help doctors predict how well treatments will work for people with stage II-III triple negative breast cancer.

What this trial studies

This observational study focuses on patients with stage II-III triple negative breast cancer (TNBC) who are candidates for neoadjuvant chemotherapy, with or without immune checkpoint inhibitors. It aims to analyze various tissue samples using multiomics approaches, including whole genome sequencing and microbiome analysis, to establish predictive biomarkers of treatment response. The study will integrate data from these analyses to develop a clinical tool that assists clinicians in making informed treatment decisions for TNBC patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically confirmed stage II-III triple negative breast cancer who are eligible for neoadjuvant chemotherapy.

Not a fit: Patients with metastatic disease or those not eligible for neoadjuvant chemotherapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized treatment strategies that improve outcomes for patients with triple negative breast cancer.

How similar studies have performed: Other studies have shown promise in using multiomics approaches to identify biomarkers in cancer treatment, suggesting potential success for this novel approach.
