About the research
This study will include up to 40 participants with Grade 2 or Grade 3 IDH1-mutant glioma who have undergone surgery and received vorasidenib as their only treatment, experienced radiographic disease progression on vorasidenib (confirmed by Blinded Independent Central Review \[BICR\] per modified Response Assessment in Neuro-Oncology \[RANO\] 2.0), and are not in need of immediate chemotherapy or radiotherapy.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
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.
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Safusidenib
Safusidenib 250 mg BID
Drug: Safusidenib
Safusidenib DRUG
Safusidenib administered twice daily as a single agent orally on Days 1 to 28 of a 28-day cycle. Participants may continue treatment until disease progression or another reason for discontinuation occurs.
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Objective Response Rate (ORR) per modified Response Assessment in Neuro-Oncology (RANO) 2.0 assessed by Blinded Independent Central Review (BICR)
Time frame: From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months
ORR defined as the proportion of participants with the confirmed best overall response of Complete Response (CR), Partial Response (PR) or Minor Response (MR) per modified RANO 2.0, assessed by BICR
Secondary measures
ORR per modified RANO 2.0 assessed by Investigator
Time frame: From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months
ORR defined as the proportion of participants with the confirmed best overall response of CR, PR or MR per modified RANO 2.0, assessed by the Investigator
Volumetric Tumor Growth Rate (TGR) by BICR
Time frame: From historical scans through the final scan in the study, approximately 18 months
TGR defined as the percentage change in tumor volume by unit of time, assessed by BICR
Duration of Response (DOR) per modified RANO 2.0 assessed by BICR and by Investigator
Time frame: From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months
DOR, time from the first documentation of objective response (CR, PR, or MR) to the date of the first occurrence of radiographic disease progression per modified RANO 2.0 assessed by BICR and by the Investigator or death from any cause, whichever occurs earlier.
Time to Next Intervention (TTNI)
Time frame: From the date of first dose of study drug until the date of the start of another anticancer treatment or date of death, approximately 18 months
TTNI, defined as the time from the first dose of study drug to the initiation of first subsequent anticancer therapy or death from any cause, whichever occurs earlier
Progression Free Survival (PFS) per modified RANO 2.0 assessed by BICR and by Investigator
Time frame: From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months
PFS, defined as the time from the first dose of study drug to the date of the first occurrence of radiographic disease progression per modified RANO 2.0 assessed by BICR and by the Investigator or death from any cause, whichever occurs earlier.
Time to Response (TTR) per modified RANO 2.0 assessed by BICR and by Investigator
Time frame: From the date of first dose of study drug to the first documentation of objective response (CR, PR, or MR), approximately 18 months
TTR, defined as the time from the first dose of study drug to the first documentation of objective response (CR, PR, or MR) per modified RANO 2.0, assessed by BICR and by the Investigator
Overall Survival (OS)
Time frame: From the date of first dose of study drug until the date of death, approximately 18 months
OS, defined as the time from the first dose of study drug to death from any cause.
Safety and tolerability
Time frame: From the date of first dose of study drug until 30 days after the date of the last dose of study drug, approximately 18 months
The safety and tolerability of safusidenib evaluated based on AEs graded by NCI-CTCAE version 5.0, laboratory abnormalities as graded by NCI-CTCAE version 5.0, vital signs, physical examinations, and ECGs
Seizure Activity
Time frame: From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months
Evaluate seizure frequencies and severity including type of seizure, seizure-related AEs, and changes in anti-epileptic medications in participants receiving safusidenib
Review the complete result tables and limitations in the official record.
