Ataraxis AI test to predict response to neoadjuvant chemotherapy in breast cancer

Official title: A Prospective Non-Interventional Study Using a Multi-Modal Prognostic Test (Ataraxis) for Evaluating the Clinical Integration in Early-Stage Invasive Breast Cancer

Run by Incheon St.Mary's Hospital · NCT07327970 · Data updated 2026-11-12

This project will try the Ataraxis AI test on digitized biopsy slides and basic clinical data to see if it can predict which adults with stage I–III breast cancer will have a complete response to neoadjuvant chemotherapy.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with histologically confirmed Stage I–III invasive breast cancer who are planned for neoadjuvant chemotherapy, have H&E-stained core needle biopsy slides available, and can provide informed consent.

Probably not a fit

Patients with metastatic (Stage IV) disease, those not eligible for neoadjuvant chemotherapy, or those without obtainable biopsy slides are unlikely to receive benefit from participation.

What this trial studies

This observational, single-center study integrates the Ataraxis AI model into routine clinical workflow using digitized H&E core biopsy images plus basic clinical variables (age, tumor stage, hormone receptor status) to generate a risk score. It has two stages: Stage 1 (30 patients) examines practical workflow factors such as ease of use, report clarity, and processing time, and Stage 2 (70–120 additional patients) validates AI-predicted pathological complete response (pCR) against surgical pathology outcomes. Treating physicians remain blinded to AI predictions to avoid altering clinical decisions based on the score. Primary endpoints are workflow feasibility metrics in Stage 1 and the accuracy of pCR prediction compared with surgical outcomes in Stage 2.

Why it matters

Potential benefit: If successful, the test could help identify who is likely to achieve a pathological complete response and support more personalized neoadjuvant treatment decisions.

How similar studies have gone: Prior retrospective development studies reported that similar AI approaches can predict recurrence or response with accuracy comparable to or better than some genomic tests, but prospective real-world validation is limited.
