Evaluating blood protein profiles to predict metastatic relapse in triple negative breast cancer

INSTIGO Trial: Evaluation of a Plasma Protein Profile as a Predictive Biomarker for Metastatic Relapse in Triple Negative Breast Cancer Patients

Centre Jean Perrin · NCT04438681

This study is testing if certain blood proteins and other markers can help predict if patients with triple negative breast cancer will have a relapse after treatment.

What this trial studies

The INSTIGO study aims to assess the concentrations of plasma proteins at various stages of follow-up in patients with triple negative breast cancer to determine their predictive ability for metastatic relapse. Additionally, the study will explore other potential biomarkers, including Tumor-infiltrating Lymphocytes, circulating tumor DNA, and a tumor RNA signature. Blood samples will be collected before treatment and at multiple points during and after treatment to analyze these biomarkers. This approach seeks to provide a comprehensive understanding of factors influencing metastatic recurrence.

Who should consider this trial

Good fit: Ideal candidates are females over 18 years old diagnosed with non-metastatic, histologically confirmed triple negative breast cancer.

Not a fit: Patients who are unable to provide consent or are under guardianship will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved predictive tools for monitoring metastatic relapse in triple negative breast cancer patients.

How similar studies have performed: Other studies have shown promise in using blood-based biomarkers for cancer prognosis, but this specific approach is novel.
