Personalized therapy using patient-derived organoids for metastatic breast cancer

Efficacy of Personalized Tumorogram-based Therapy in Cancer Established From Patient-derived Biological Avatar: Proof-of-concept Study

Not applicable Interventional Institut Curie · NCT06459791

This study is testing whether using mini versions of a patient's breast tumor can help find the best treatment options for people with metastatic breast cancer.

What this trial studies

This clinical trial involves taking a biopsy from a breast tumor to create patient-derived organoids (PDOs), which serve as avatars for personalized treatment. A drug screening will be conducted on these organoids to determine which therapies are most effective for the individual patient. Based on the results, a personalized tumorogram will be generated, predicting the tumor's sensitivity to various drugs. Patients will continue standard care while awaiting their tumorogram results, and treatment recommendations will be made by a multidisciplinary committee based on the findings.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with advanced breast cancer, specifically those with triple-negative or hormone receptor-positive breast cancer that has progressed after hormone therapy.

Not a fit: Patients with more than three lines of chemotherapy in the advanced setting or those with progressive brain or leptomeningeal metastases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and tailored treatments for patients with metastatic breast cancer.

How similar studies have performed: While personalized medicine approaches using organoids are emerging, this specific methodology is relatively novel and has not been extensively tested in similar studies.
