Brief summary
Background: Despite improvements in the treatment of Triple Negative Breast Cancer (TNBC), the cancer returns in half of the women and shockingly 40% are dead within 5 years of their initial cancer diagnosis. There is an urgent need to identify reliable biomarkers of response for chemotherapy and immunotherapy. Study Aims: To update Concr's existing predictive algorithms specifically for use in women newly diagnosed with TNBC. The plan is develop technology which will predict which drug the cancer will respond best to, treatment A vs. treatment B AND how the individual's prognosis could change if treatment A is chosen overtreatment B. Study Design: The VISION study is a clinical study looking back in time (retrospective study), specifically focusing on women who were previously diagnosed with early Triple Negative breast cancer and received chemotherapy followed by curative breast surgery. The plan is to collect historical clinical data and previously collected cancer biopsy samples from up to 200 women in order to update Concr's existing treatment prediction algorithms. Hence there are no extra research biopsies needed in order to participate in the Study. Study Sites: UK and Australia Study Funding: This study is funded by the a Techbio company called Concr with support from Innovate UK (UK Government funding).
Detailed description
VISION is a commercially sponsored clinical trial designed to be a retrospective, observational non-CTIMP research study which will collect archival tumour samples from participants previously treated with chemotherapy +/- immunotherapy for early Triple Negative Breast Cancer (TNBC). Current Study design: VISION currently has 2 retrospective patient cohorts: 1. Arm A: Patients treated with neoadjuvant chemotherapy who had a complete pathological response (n = 100), 2. Arm B: Patients treated with neoadjuvant chemotherapy who had a residual cancer burden (n=100). Planned study design: Include a prospective arm, Arm C to test feasibility of generating treatment predictions in real time. Study sites: UK and Australia Study timelines: 2 years UK start date: April 26th, 2024 Datasets planned for collection are: 1. Clinical data about the individual, cancer stage at diagnosis, cancer treatment, treatment response and clinical outcome, 2. Genomic data from diagnostic breast cancer samples +/- surgical samples, 3. Whole Slide Imaging data from tumour sections. Planned Next Generation Sequencing of tumours: 1. RNA sequencing 2. DNA sequencing 3. Other NGS approaches or -OMICS (subject to tissue availability) Planned tissue collection: Tissue type: Archival FFPE samples Diagnostic samples (before chemotherapy) +/- surgical samples (after chemotherapy) Planned technology development: Existing Concr technology which predicts cancer response, currently pan-cancer, in the early Triple Negative Breast Cancer population A key objective is to demonstrate that accurate prediction of therapeutic response for chemotherapy, specifically anthracyclines, taxanes, platinums, anti-metabolites with/without immunotherapy.

Inclusion criteria
Key Inclusion Criteria: * Age: ≥ 18 years * Mental Capacity: Individual should be able to give informed consent, if alive * Triple Negative Breast Cancer (TNBC) * Oestrogen receptor (ER) negative with an Allred score of ≤ 2 or, equivalent pathology scoring system e.g., ≤10% (0 - 10%) tumour nuclei staining * HER2 negative: 1+ on immunohistochemistry or 2+ immunohistochemistry and FISH/D-Dish negative * Progesterone receptor (PgR) negative = PgR score of ≤2 or equivalent pathology scoring system e.g., ≤10% (0 - 10%) tumour nuclei staining * Androgen receptor (AR) status (if known): negative or positive * TNBC phenotype: HER2 negative tumours with borderline ER or PgR scoring on immunohistochemistry e.g., ER 3/8 and PgR 0/3 negative which were managed as early TNBC can be included but should be discussed on a case-by-case basis prior to study registration with Principal Investigator. * Lymph node involvement: Lymph node negative or positive; any number including clinical/pathological N3 involvement (TNM staging ≥ V.8.0) * Cancer Staging: Stage 2 or stage 3 breast cancer * Treated considered standard of care neoadjuvant chemotherapy: an anthracycline, a taxane, an alkylating agent, +/- a platinum, +/- immunotherapy * Available archival tissue samples Key
Exclusion criteria
* Stage IV de novo metastatic breast cancer are not eligible * Stage I breast cancers are not eligible * Women who were diagnosed with more than one cancer type within 3 years of the breast cancer diagnosis of TNBC are not eligible * Received neoadjuvant radiotherapy * Received neoadjuvant endocrine treatment * Women pregnant at the time of the TNBC diagnosis * Significant medical co-morbidities which could have influenced the participant's prognosis are excluded. Examples include cardiac failure, moderate - severe renal failure, active hepatitis, HIV, active TB, ischaemic heart disease etc.
