Katherine B. Peters, MD, PhD, discusses findings from the phase 3 INDIGO trial of vorasidenib in patients with recurrent or residual grade 2 glioma harboring an IDH1 or IDH2 mutation and how these results support the addition of vorasidenib to the treatment armamentarium. 

In this first episode of OncChats: Examining LIFU–Aided Liquid Biopsy in Glioblastoma, Manmeet Singh Ahluwalia, MD, MBA, FASCO, and Michael W. McDermott, MD, explain how low-intensity focused ultrasound works and the rationale for examining its use in cancer and other conditions.

The protein arginine methyltransferase 5 brain-penetrant inhibitor PRT811 demonstrated preliminary antitumor activity and acceptable safety for patients with recurrent high-grade glioma and advanced or metastatic uveal melanoma, according to data from the dose-expansion portion of a phase 1 trial presented at the 2023 ASCO Annual Meeting.

Treatment with tovorafenib elicited encouraging and fast onset responses in heavily pretreated pediatric patients with low-grade glioma regardless of response assessment criteria, according to data from the phase 2 FIREFLY-1 trial that were presented at the 2023 ASCO Annual Meeting.
