Using brain imaging to predict treatment response in patients with brain metastases

Imaging Trial of Biomarkers to Guide Individualized Therapy in Patients With Brain Metastasis Receiving Radiotherapy

Phase 2 Interventional University Health Network, Toronto · NCT04197297

What this trial studies

This study focuses on patients with brain metastases who are scheduled to receive radiation treatment. Participants will undergo CT and MRI scans before and after their treatment to measure specific biomarkers that may indicate how well they will respond to the therapy. The goal is to validate the predictive abilities of these imaging biomarkers, which could help tailor treatment plans for better outcomes. Conducted at the Princess Margaret Cancer Center, this single-center phase II study aims to enroll up to 90 patients over a two-year period.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with biopsy-proven primary malignancies and brain metastases who are planned for radiation treatment.

Not a fit: Patients who have previously undergone whole brain radiotherapy or radiosurgery to the index lesion may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment personalization for patients with brain metastases, enhancing their response to radiation therapy.

How similar studies have performed: Previous studies have suggested that imaging biomarkers can predict treatment response, indicating that this approach has potential based on earlier findings.
