Abstract

Isocitrate dehydrogenase (IDH)-mutant gliomas are the most common malignant primary brain tumors in young adults. This condition imposes a substantial burden on patients and their caregivers, marked by neurocognitive deficits and high mortality rates due to tumor progression, coupled with significant morbidity from current treatment modalities. Although surgery, radiation therapy, and chemotherapy improve survival, these treatments can adversely affect cognitive function, quality of life, finances, employment status, and overall independence. Consequently, there is an urgent need for innovative strategies that delay progression and the use of radiation therapy and chemotherapy. The recent Federal Drug Administration (FDA) approval of vorasidenib, a brain-penetrant small molecule targeting mutant IDH1/2 proteins, heralds a shift in the therapeutic landscape for IDH-mutant gliomas. In this review, we address the role of vorasidenib in the treatment of IDH-mutant gliomas, providing a roadmap for its incorporation into daily practice. We discuss ongoing clinical trials with vorasidenib and other IDH inhibitors, as single-agent or in combination with other therapies, as well as current challenges and future directions.

Proposed incorporation of vorasidenib in the management algorithm based on INDIGO data and Federal Drug Administration (FDA) label. *FDA approval also includes patients with WHO grade 2 gliomas who have had a gross total resection (GTR). The discrepancy between the FDA label and the INDIGO criteria might be justified by the difficulty in assessing residual disease after surgery and the presence of microscopic infiltrative disease beyond imaging abnormalities in virtually all glioma patients. Indication for this population may vary depending on countries. **As assessed by the physician, no consensus on “high-risk” criteria.
