Lower-grade glioma: research and therapeutic landscape

12 genes recurrently implicated in lower-grade glioma, triaged for whether anything can actually be aimed at them. The zeros are the informative rows.

Of 12 recurrently implicated genes, 7 carry any drug at all. That is a statement about these 12 gene targets, not about the disease: Lower-grade glioma does have labelled therapy — 2 drugs, listed in the next section.

Dataset evidence counts studies in the 73-study ranked set whose title or abstract names the gene; the bar is scaled to IDH1. Sources: Open Targets Platform and NCBI GEO, retrieved 2026-09-12. Clinical stage is the highest reached for any indication — see the per-drug indications noted in each row. Target-prioritisation reference only; not clinical or prescribing guidance.

2 drugs carry an FDA label naming lower-grade glioma: Temozolomide, Vorasidenib. Separately, 21 of the drugs returned for the genes in the table above are approved only for other diseases and reach lower-grade glioma through trials, not through their labels.

Every label that names lower-grade glioma

1 labels match indications_and_usage:"grade 2 astrocytoma" OR indications_and_usage:"grade 2 oligodendroglioma" OR indications_and_usage:"astrocytoma or oligodendroglioma" OR indications_and_usage:"anaplastic astrocytoma" OR indications_and_usage:"oligodendroglioma" OR indications_and_usage:"IDH1 or IDH2 mutation"; they collapse to 2 distinct molecules once salt forms, biosimilars and co-formulated hyaluronidase are merged. Source: openFDA drug label API (api.fda.gov/drug/label.json), retrieved 2026-09-12. Labels change; this reflects the current label text, not the approval history. Not prescribing guidance.

No cell-therapy trial in this disease names one of the antigens in the profile. That is a finding, not a gap in the query: the antigens searched are listed in the machine-readable facts alongside the synonyms used.

Every term below is a share of the lower-grade glioma literature, not a count, because the field itself grew: 2015–2018 (n=769) against 2021–2025 (n=778). A topic whose papers doubled while the field doubled has not risen.

Publication mix

Query: Astrocytoma[MeSH Major Topic] NOT ("Glioblastoma"[MeSH] OR "Optic Nerve Glioma"[MeSH] OR "Medulloblastoma"[MeSH] OR "Ependymoma"[MeSH]). Terms need at least 12 papers in the recent window and, in the rising table, at least 5 in the earlier one — a term going from 1 paper to 12 is a large fold change and no evidence of anything. Ubiquitous descriptors (Humans, Animals, age bands) and the disease’s own term are dropped. Source: PubMed MeSH, retrieved 2026-09-12.

What the public sources count, and how closely each category matches this disease. The same figures for every disease on the site are on one table.

Years of life lost: not computed. Years of life lost needs survival, age at diagnosis and a case count. five_year_relative_survival, median_age_at_diagnosis is not recorded for this disease.

NIH obligations naming lower-grade glioma, after removing the 55 records across all years that matched the search but are about something else. That filter is not cosmetic: without it this section reports another field’s funding as this disease’s.

NIH obligations by fiscal year

Where FY2023 money went

Text search lower-grade glioma OR low-grade glioma OR oligodendroglioma OR IDH-mutant glioma over project title, terms and abstract, per fiscal year. Awards are individual funding actions; distinct projects collapse them by core project number, so a multi-year grant counts once. The most recent year may be incomplete. Source: NIH RePORTER, retrieved 2026-09-12.

Who funds it, FY2023

The total says how much. These say who from, through what kind of award, and to whom — which a dollar figure cannot.

2,598 human GEO series match lower-grade glioma. Keyword relevance cannot tell a 6,341-sample patient cohort from a six-well cell-line experiment, so this ranking scores four things GEO does not expose: how often the accession is named in full-text papers, field-normalised citation impact, clinical annotation, and cohort type.

Composition of the 73-study ranked set

Sources: NCBI GEO + Europe PMC + iCite, retrieved 2026-09-12. SubSeries are collapsed to one row per study by linked PMID. Of 2,541 series retrieved, 1,962 were dropped by the profile’s exclusion rules and 492 named the disease only in passing. The ranked set is a relevance-ranked sample, not a census, so the composition figures describe the sample only.

Each card below is a disagreement between two of the tables on this page — a drug that exists but was never tried here, a target that looks tested and was not, a gene with no drug whose product has a busy clinical programme. They are computed from the same facts as the tables, so they cannot contradict them.

This page is written to be quoted correctly by a model as much as read by a person. The same facts are available as JSON at the sibling URL below, which is what to cite. The cross-disease layer — burden, genes, drugs and antigens across every briefing — is described at /disease/api.json.
