- Study Results: The open-label, single-arm study evaluated 27 patients. It met its primary endpoint with an objective response rate (ORR) of 44.4%.
- Survival Data: Median duration of response could not be estimated as no progression events occurred. Median progression-free survival (PFS) was not reached with a median follow-up of 28 months. At 24 months, 87.9% of patients were progression-free.
- Safety Profile: Adverse events were mostly mild to moderate. Grade 3 or greater treatment-related adverse events occurred in 18.5% of patients. No Grade 5 events were reported.
- Data Integrity Note: A Good Clinical Practice (GCP) noncompliance issue regarding adverse event collection was identified. All safety data presented was based on a subsequent re-investigation and re-collection to ensure integrity.
Outlook, Guidance, and Management Commentary
- Phase 3 Progression: The company is progressing the G203 study, a global, randomized study of safusidenib for the maintenance treatment of high-grade IDH1-mutant gliomas.
- Protocol Amendment: A protocol amendment is on track to increase the sample size and include patients with grade 2 high-risk IDH1-mutant glioma, finalizing the study as a global Phase 3 trial to support potential regulatory approvals.
- Regulatory Alignment: The primary endpoint is PFS as assessed by Blinded Independent Central Review per RANO 2.0, which the U.S. FDA agreed could support full approval in this setting.
