Using organoids to predict chemotherapy response in osteosarcoma

An Organoid-based Functional Precision Medicine Trial in Osteosarcoma: PREMOST

Observational Jonsson Comprehensive Cancer Center · NCT06064682

This study is trying to see how well different chemotherapy drugs work on osteosarcoma by testing them on tiny lab-grown versions of the tumors.

What this trial studies

This study aims to determine the sensitivity of osteosarcoma to various chemotherapy agents by utilizing tissue cultures in the laboratory. Researchers will establish organoids from tumor samples obtained during routine biopsies or surgeries, allowing for the assessment of how these organoids respond to different treatments. The study will also incorporate genetic testing to enhance understanding of osteosarcoma and its treatment responses. The innovative miniaturized system developed allows for efficient testing of multiple drug combinations and treatment protocols on these organoids.

Who should consider this trial

Good fit: Ideal candidates include patients with imaging studies suggestive of osteosarcoma who are scheduled for a biopsy or surgery.

Not a fit: Patients who have already been diagnosed with osteosarcoma and are not undergoing biopsy or surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective treatment options for patients with osteosarcoma.

How similar studies have performed: Other studies have shown promise in using organoid models for predicting treatment responses in various cancers, suggesting a potential for success in this novel approach for osteosarcoma.
