Precision Oncology Clinical Diagnostic Study In Primary and Metastatic Breast Cancer (PRISM)

Condition(s) studied

Investigational drug(s) / intervention(s)

TSO500 Assay: Utilisation of TSO500 assay to identify somatic, clinically actionable somatic in the primary breast tumour and, where relevant, brain metastatic tumour to the treating physician to inform clinical management of participating patients.

Study summary

This study aims to provide information about the genomics of your breast cancer which your oncologist can use to enhance the treatment of your disease possibly enabling more targeted and personalised therapy.This study will carry out TruSight Oncology Comprehensive (TSOComprehensive) testing on breast cancer tumour tissue that was collected at the time of your breast cancer diagnosis or during your breast surgery or if you have brain metastasis and you have had a biopsy for this. The TruSight Oncology Comprehensive assay is a next-generation sequencing (NGS) test used to analyse cancer-related genomic changes in patients, offering a comprehensive view of potential mutations and other alterations that can impact treatment decisions. The TruSight Oncology Comprehensive assay is CE-IVD marked for use in Europe, meaning that it complies with the relevant EU regulation, for comprehensive genomic profiling for different types of cancer. It analyses 523 cancer-relevant genes from both DNA and RNA to identify variations. It will also look for changes and mutations which may affect cell growth and stability. By identifying relevant mutations and biomarkers, the assay can help oncologists select the most appropriate treatment strategies with the aim of improving patient outcomes.

Eligibility

Primary outcome measure(s)

• Proportion of enrolled patients with at least one clinically actionable mutation identified by PRISM diagnostics compared with standard-of-care diagnostics. — At the time of therapeutic decision following diagnostic assessment (up to 6 weeks from enrollment).
