About DIPG / Diffuse Midline Glioma trials

DIPG (now classified more broadly as diffuse midline glioma, DMG, under WHO 2021 criteria) is defined molecularly by H3 K27M-altered status. H3-3A (encoding histone H3.3) carries the K27M mutation in roughly 80% of DIPG cases; the H3.1 variant (encoded by HIST1H3B/C, not in this panel) accounts for most of the rest. ACVR1 mutations occur in about 25% of DIPG, often co-occurring with H3.1 K27M and driving aberrant BMP signaling. PPM1D phosphatase mutations occur in 10-15% and contribute to treatment-resistance biology.

Trial selection in DIPG and DMG depends on age, tumor location, and H3 K27M status. Imipridone-class trials (following the 2025 accelerated approval of dordaviprone for progressive H3 K27M-mutant DMG after prior therapy) are an active targeted-therapy space, with combinations and earlier-line use in development. ACVR1 inhibitor trials enroll the ACVR1-mutant subset, particularly common in younger patients. Re-irradiation trials test repeat radiation strategies for progression after initial focal radiation. CAR-T trials directed at B7-H3 or GD2 are an active emerging area distinct from the blood-cancer CAR-T space. Convection-enhanced delivery (CED) trials test direct intratumoral delivery of agents that don't cross the blood-brain barrier well. Combination trials test radiation with targeted agents to extend response duration.

DIPG / DMG trial screening typically checks H3 K27M status, age, and prior radiation exposure. Tumor location (classic pontine DIPG vs other midline locations like thalamus or spinal cord) gates some trials and determines surgical accessibility. H3 K27M mutation confirmation is required for imipridone-class trials. Prior radiation dose and field for re-irradiation eligibility (typically requires sufficient time and dose-volume thresholds). Steroid dose, with many trials capping dexamethasone for IO and vaccine trials. Performance status using Lansky scale for younger patients or Karnofsky for older. Age cutoffs vary widely: pediatric trials typically include patients up to 18 or 21, while DMG trials in young adults are often separate.
