Current and Future Management of IDH-Mutant Low-Grade Glioma — Video Lecture

Faculty

TARGET AUDIENCE
This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of IDH-mutant low-grade glioma.

LEARNING OBJECTIVES

• Appreciate the incidence of IDH1/2 mutations in patients with low-grade glioma, and understand the biological rationale for the development of therapies designed to target these abnormalities in individuals with the disease.
• Recognize available efficacy and safety findings with the use of novel IDH inhibitors for low-grade glioma and assess the potential role these agents may play in the treatment of the disease.
• Understand the toxicities associated with novel IDH inhibitors under development for low-grade glioma in order to prepare for the potential clinical availability of these agents.
• Recall the design of ongoing clinical trials evaluating novel IDH inhibitors for glioma, and counsel appropriate patients about availability and participation.
