Abstract:
Standard treatment for patients with IDH-mutant gliomas with radiation therapy and chemotherapy is non-curative and associated with long-term neurotoxicity. This has created intense interest in targeted therapeutic strategies that are specifically designed of IDH-mutant tumors. Much progress has been made in understanding the unique biology of IDH-mutant gliomas, and now various IDH-mutant-specific targeting strategies are in various phases of development. Here, we will review a range of IDH-mutant targeting treatments being explored, including direct IDH inhibitors, as well as strategies that take advantage of IDH-mutant-specific vulnerabilities.
Insights
Targeted therapies are being developed for isocitrate dehydrogenase (IDH)-mutant gliomas, offering new hope beyond non-curative standard treatments. These strategies exploit unique tumor biology to improve outcomes for patients with IDH-mutant brain tumors.
