Monitoring soluble CD146 levels in glioblastoma patients treated with bevacizumab

Predictive Value of Soluble CD146 in Patients With Recurrent Glioblastoma Treated by Bevacizumab

Not applicable Interventional Assistance Publique Hopitaux De Marseille · NCT06001281

This study is testing if tracking a specific protein in the blood can help understand how well glioblastoma patients are responding to treatment with bevacizumab.

What this trial studies

This study aims to prospectively monitor the levels of soluble CD146 in the plasma of patients with recurrent glioblastoma who are being treated with the anti-VEGF antibody bevacizumab. Patients will have plasma samples collected at various points: before the first and second bevacizumab administrations, at the time of the first MRI evaluation, and at disease progression. The goal is to analyze the correlation between soluble CD146 levels and patient outcomes, particularly in relation to resistance to bevacizumab treatment.

Who should consider this trial

Good fit: Ideal candidates are adult patients with recurrent IDHwt glioblastoma who have relapsed after standard first-line treatment and are candidates for bevacizumab.

Not a fit: Patients who are pregnant, have a life expectancy of less than three months, or have received bevacizumab as first-line treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a predictive biomarker for treatment response in glioblastoma patients receiving bevacizumab.

How similar studies have performed: While the specific approach of monitoring soluble CD146 in this context may be novel, previous studies have indicated the importance of biomarkers in predicting treatment responses in glioblastoma.
