New hope for glioblastoma? drug combo trial targets aggressive brain tumors
NCT ID NCT07326566
First seen Jun 25, 2026 · Last updated Sep 17, 2026 · Updated 18 times
Summary
This Phase 2 trial tests whether adding the experimental drug silevertinib to standard chemotherapy (temozolomide) helps people with a specific type of newly diagnosed glioblastoma live longer without their cancer worsening. The study includes 162 participants whose tumors have certain genetic markers (unmethylated MGMT and EGFRvIII). After surgery and radiation, some get the combo, others get chemotherapy alone, and researchers compare outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- silevertinib (an oral EGFR inhibitor) combined with temozolomide (chemotherapy)
- What this could lead to
- If it works, this could improve how long people with a hard-to-treat type of glioblastoma live without their cancer growing, compared to standard chemotherapy alone.
- What could go wrong
- This is a Phase 2 trial with only 162 participants, so results are still early. The combination may not work better than temozolomide alone, and side effects from the two drugs together could be more severe.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Key Inclusion Criteria: * Newly diagnosed histologically confirmed glioblastoma that is isocitrate dehydrogenase wild type (IDH-WT). * Positive EGFR status in the brain tumor as determined by a commercially available test or validated laboratory assay (CLIA or comparable certification). * For Part 1 (Safety Lead-in) ONLY: EGFR alterations. * For Part 2 (Randomized, Controlled Trial) ONLY: EGFRvIII. * For Part 2 (Randomized, Controlled Trial) ONLY: Unmethylated MGMT promoter tumor status based on a validated assay. * No treatment for newly diagnosed GBM other than surgery followed by standard-of-care adjuvant postoperative radiation (54 to 60 Gy) and TMZ chemotherapy. * At least 4 weeks since completion of radiation therapy, with a post-radiation MRI showing no progression. Key Exclusion Criteria: * Recurrent multifocal disease, metastatic, leptomeningeal, or extracranial GBM, or gliomatosis cerebri. * Progression of GBM prior to Enrollment, Screening, or Randomization. * Biopsy-only/no resectional surgery. * Prior or concomitant treatment for GBM with an EGFR-targeting agent, including silevertinib, bevacizumab, cytotoxic chemotherapy, immunotherapy, experimental therapies, Gliadel wafers, GammaTile®, or other intratumoral or intracavitary antineoplastic therapy. * Intent to use Optune® (TTF). * Significant other uncontrolled health conditions or other malignancies.
