Window of Opportunity Study of DSP-0390 in Gliomas

This study focuses on determining the pharmacokinetic and pharmacodynamic effect of DSP-0390 in brain and blood from patients with IDH-mutant glioma undergoing tumor resection. Tissue will be collected during surgical resection. Blood will be drawn at various time points throughout the 2 weeks of treatment. The hypothesis is that DSP-0390 will accumulate in brain tumor tissue at pharmacologically relevant concentrations, and that alterations in cholesterol metabolism driven by mutant IDH will increase susceptibility to DSP-0390 and lead to tumor cell death.
