Trial summary

Initially described in 2009 on LGR5 positive stem cells from intestine, organoids correspond to a 3D cell culture that preserves the organization and part of the initial function of the organ from which the cells were derived. Read more about this study

About this study

Initially described in 2009 on LGR5 positive stem cells from intestine, organoids correspond to a 3D cell culture that preserves the organization and part of the initial function of the organ from which the cells were derived. They use the proliferation and differentiation properties of stem cells cultured in a three-dimensional matrix.

These principles have been adapted to many human organs, including the breast. These culture conditions have thus allowed the establishment of cancer organoid lines that have the advantages of rapid amplification, a high rate of establishment success and unlimited proliferation potential. They are transfectable and cryopreservable. They are very close morphologically and genetically to the tumor from which they derive. Very recently, the in vivo response of orthotopic xenograft models of breast cancer organoids has been correlated to the in vitro response of these same organoids. In addition, the in vitro response of various of these models to PARP inhibitors was linked to the presence of the BRCA1/2 mutant signature, highlighting the potential of these models to predict patient response to these treatments.

Furthermore, one study demonstrated the value of using organoids derived from metastatic gastrointestinal tumors to predict patient response to cancer treatments (100% sensitivity, 93% specificity, 88% positive predictive value, and 100% negative predictive value.

Questions about this trial

What is this clinical trial studying?

An observational study of Triple Negative Breast Cancer and Organoid, run by Centre Francois Baclesse at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 19 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact George EMILE, MD (+33 2 31 45 50 50, g.emile@baclesse.unicancer.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of establishment of exploitable organoids tumor (time frame: 4 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05404321, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2026.
