Gene mapping could open new doors for brain tumor patients
NCT ID NCT05186064
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether whole genome sequencing of recurrent glioblastoma tumors can uncover more targeted treatment options. Researchers analyzed tumor samples from 164 patients who had surgery for their first recurrence. The goal was to see if this detailed genetic testing could identify additional therapies beyond standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- whole genome sequencing (diagnostic test)
- What this could lead to
- If successful, this approach could help doctors identify more personalized treatment options for recurrent glioblastoma patients.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly improve survival or outcomes for participants.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Histopathologically confirmed IDH wild type glioblastoma, first recurrence after standard chemoradiation; suitable for standard-of-care re-resection; 2. Age ≥ 18 years; 3. Able and willing to give written informed consent; 4. Life expectancy \>3 months, allowing adequate follow-up of toxicity evaluation and antitumor activity; 5. KPS performance status ≥70. Exclusion Criteria: 1. Currently actively treated in another antitumor clinical trial (excluding DRUP and STELLAR studies); 2. Patients with any other clinically significant medical condition which, in the opinion of the treating physician, makes it undesirable for the patient to participate in medication studies or which could jeopardize compliance with study requirements including, but not limited to ongoing or active infection, significant uncontrolled hypertension, or severe psychiatric illness/social situations.
