New hope for brain tumor patients when standard drug fails
NCT ID NCT07703436
First seen Jul 14, 2026 · Last updated Aug 28, 2026 · Updated 7 times
Summary
This study tests an experimental drug called safusidenib in people with a slow-growing brain tumor (IDH1-mutant glioma) whose tumor got worse while on the standard drug vorasidenib. Up to 40 participants take safusidenib pills twice daily to see if the tumor shrinks or stops growing. The goal is to find a backup option for patients who run out of effective treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- safusidenib
- What this could lead to
- If safusidenib works, it could offer a new treatment option for people with IDH1-mutant glioma whose tumors stop responding to the current standard drug.
- What could go wrong
- This is a small, early-phase trial with only 40 participants, so results may not apply to everyone. The drug may not shrink tumors or could cause side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Key Inclusion Criteria: * Histologically confirmed Grade 2 or 3 IDH-mutant astrocytoma or IDH-mutant and 1p19q co-deleted oligodendroglioma, according to WHO CNS 2021 criteria * IDH1 mutation (e.g., R132H/C/G/S/L) based on immunohistochemistry (IHC) (R132H only), PCR, or next generation sequencing (NGS). * Have had at least 1 prior surgery for glioma (biopsy, sub-total resection, or gross total resection). * Measurable disease per modified RANO 2.0 confirmed by BICR during Screening. * Previously treated with vorasidenib and experienced radiographic disease progression during treatment and are not in need of immediate chemotherapy or radiotherapy in the opinion of the Investigator. Disease progression must be confirmed by BICR using modified RANO 2.0. * Adequate hematologic and organ function * Expected survival of ≥12 months Key Exclusion Criteria: * Any prior anticancer therapy other than surgery (biopsy, sub-total, or gross total resection) and vorasidenib for treatment of glioma. * Discontinued vorasidenib for toxicity or any reason other than radiographic disease progression * Prior treatment with anti-angiogenic agents such as Avastin (bevacizumab) or investigational agents for glioma. * Brainstem or spinal cord involvement either as primary location, site of multifocal involvement, or by significant tumor extension. * Significant functional or neurocognitive deficits, including uncontrolled seizures * Evidence of leptomeningeal disease. * Use of therapeutic doses of steroids for signs/symptoms of glioma. Participants taking physiologic doses (defined as equivalent of \<1.5 mg of dexamethasone equivalent) for medical conditions not related to glioma will be permitted.
