Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with a histological diagnosis of glioblastoma and a life expectancy of more than six months.

Probably not a fit

Patients with metastatic disease or those who have received prior systemic anti-cancer therapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to treat patients with newly diagnosed glioblastoma by identifying effective personalized drug regimens through high-throughput screening of cancer stem cells derived from their tumors. A panel of FDA-approved drugs will be tested to find a combination of up to three candidates that can be used alongside standard chemoradiation therapy. The selected drug candidates will be evaluated for safety and efficacy by a team of pharmacists and physicians before treatment initiation. This approach seeks to enhance treatment outcomes by tailoring therapies to individual patient profiles.

Why it matters

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

How similar studies have gone: While personalized approaches to cancer treatment are gaining traction, this specific method of using high-throughput screening for glioblastoma is relatively novel and has not been extensively tested in prior studies.
