New CAR-macrophages tested on patient-derived breast cancer organoids

Cohort Study to Determine the Antitumor Activity of New CAR-macrophages in Breast Cancer Patients' Derived Organoids (CARMA)

Centre Oscar Lambret · NCT05007379

This project will test whether newly developed CAR-macrophages can kill breast cancer cells grown in organoids made from patients' own tumor samples.

What this trial studies

This observational cohort collects tumor tissue and blood from adults with confirmed breast cancer who are undergoing surgery or biopsy. Tumor samples will be used to grow patient-derived organoids, three-dimensional tumor models that preserve features of each patient's cancer. Researchers will apply newly developed CAR-macrophages to these organoids to see whether the modified immune cells reduce tumor growth. Blood samples will be analyzed to characterize each patient's inflammatory status and to explore links between host factors and organoid responses.

Who should consider this trial

Good fit: Adults (18+) with histologically confirmed breast cancer of any stage who are scheduled for surgery or diagnostic tumor biopsy and who consent to donate tissue and blood are ideal candidates.

Not a fit: Patients who refuse biospecimen collection, whose tumors cannot be grown as organoids, or those seeking direct immediate treatment benefit are unlikely to receive personal therapeutic benefit from participation.

Why it matters

Potential benefit: If successful, this work could help identify CAR-macrophage approaches that more effectively kill individual patients' tumor cells and guide the development of personalized therapies.

How similar studies have performed: Preclinical studies using CAR-macrophages and patient-derived organoids have shown promising antitumor activity, but clinical evidence remains limited.
