...FDA filing acceptance and priority review for a New Drug Application (NDA) for vorasidenib, as well as the EMA granting accelerated assessment for the vorasidenib Marketing Authorization Application (MAA). This innovative targeted therapy is an oral, selective, highly brain-penetrant dual inhibitor of mutant isocitrate dehydrogenase 1 and 2 (IDH1/2) enzymes for the treatment of IDH-mutant diffuse glioma.

In the first randomized phase 3 study of a targeted therapy in grade 2 mIDH1/2 glioma, VOR significantly improved PFS by BIRC compared with PBO, with a manageable safety profile. Findings show the clinical benefit of VOR in pts for whom chemotherapy and radiotherapy are being delayed.

In a double-blind, phase 3 trial, we randomly assigned patients with residual or recurrent grade 2 IDH-mutant glioma....Progression-free survival was significantly improved in the vorasidenib group as compared with the placebo group (median progression-free survival, 27.7 months vs. 11.1 months; hazard ratio for disease progression or death, 0.39; 95% confidence interval [CI], 0.27 to 0.56; P<0.001)....In patients with grade 2 IDH-mutant glioma, vorasidenib significantly improved progression-free survival and delayed the time to the next intervention.

Servier, a global pharmaceutical group, announced today that the Phase 3 INDIGO clinical trial investigating vorasidenib in monotherapy for patients with residual or recurrent IDH mutant low-grade glioma met its primary endpoint of progression free survival (PFS) and the key secondary endpoint of time to next intervention (TTNI). The results of the prespecified interim analysis were both statistically significant and clinically meaningful.

Servier...FDA) has approved VORANIGO®, an isocitrate dehydrogenase-1 (IDH1) and isocitrate dehydrogenase-2 (IDH2) inhibitor, indicated for the treatment of adult and pediatric patients 12 years and older with Grade 2 astrocytoma or oligodendroglioma with a susceptible IDH1 or IDH2 mutation following surgery including biopsy, sub-total resection, or gross total resection.

Vorasidenib was well tolerated and showed preliminary antitumor activity in patients with recurrent or progressive nonenhancing mIDH LGG.

...patients with mutant IDH1/2 (mIDH1/2) solid tumors, including 52 patients with glioma...in patients with nonenhancing glioma was 18% (one partial response, three minor responses). The median progression-free survival was 36.8 months [95% confidence interval (CI), 11.2-40.8] for patients with nonenhancing glioma and 3.6 months (95% CI, 1.8-6.5) for patients with enhancing glioma. Exploratory evaluation of tumor volumes in patients with nonenhancing glioma showed sustained tumor shrinkage in multiple patients. Vorasidenib was well tolerated and showed preliminary antitumor activity in patients with recurrent or progressive nonenhancing mIDH LGG.
