Glioblastoma: research and therapeutic landscape

12 genes recurrently implicated in glioblastoma, 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: Glioblastoma does have labelled therapy — 3 drugs, listed in the next section.

Dataset evidence counts studies in the 1220-study ranked set whose title or abstract names the gene; the bar is scaled to EGFR. Sources: Open Targets Platform and NCBI GEO, retrieved 2026-09-30. 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.

3 drugs carry an FDA label naming glioblastoma: Bevacizumab, Carmustine, Temozolomide. Separately, 27 of the drugs returned for the genes in the table above are approved only for other diseases and reach glioblastoma through trials, not through their labels.

Every label that names glioblastoma

41 labels carry a positive indication naming the disease under indications_and_usage:"glioblastoma"; they collapse to 3 distinct molecules once salt forms, biosimilars and co-formulated hyaluronidase are merged. Source: openFDA drug label API (api.fda.gov/drug/label.json), retrieved 2026-09-18. Labels change; this reflects the current label text, not the approval history. Not prescribing guidance.

EGFRvIII is the busiest cell-therapy target among those this briefing searched in glioblastoma: 8 registered trials naming it, 2 still active. It has no gene entry of its own and is reached through EGFR: a deletion-derived mutant form of EGFR (exons 2-7 lost) rather than a separate gene, so gene-centric resources map it through EGFR.

8 of 8 shown, most recently active first. Other targets searched: IL13RA2 (6), B7-H3 (6), CD70 (2), HER2 (1), GD2 (1), EphA2 (1). Source: ClinicalTrials.gov API v2, retrieved 2026-09-18. A trial counts here when its registered conditions name glioblastoma or a tumour-agnostic basket, its title names an administered cell product, and the title names this target: a HER2 CAR-T trial that adds a PD-1 antibody is a HER2 trial. A trial stating only a product code is missed.

Every term below is a share of the glioblastoma literature, not a count, because the field itself grew: 2015–2018 (n=6,000) against 2021–2025 (n=6,000). A topic whose papers doubled while the field doubled has not risen.

These are sample shares. The two windows hold 6,166 and 10,350 papers; MeSH terms were read from an evenly spaced sample of 6,000 and 6,000 of them, taken across the whole window rather than from its most recent papers. Percentages carry sampling error of roughly a percentage point and small differences between two terms are not meaningful.

Publication mix

Query: Glioblastoma[MeSH Major Topic] NOT ("Oligodendroglioma"[MeSH] OR "Ependymoma"[MeSH] OR "Medulloblastoma"[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. Windows are read whole where they fit and sampled where they do not; the totals and the sample sizes are both in the JSON beside this page. Source: PubMed MeSH, retrieved 2026-09-11.

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 (proxy)

11.6 years per case, 151,082 a year, from survival and age at diagnosis rather than from a death count. derived proxy Not the WHO/GBD measure, which uses age at death and a life table; comparable across these briefings, not with published YLL figures. What this costs to fund is in Funding.

NIH obligations naming glioblastoma, after removing the 4,072 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 FY2025 money went

Text search glioblastoma 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 2026-09-19.

What that buys

Against 151,082 years of life lost a year, FY2025 obligations are $1,195 per life-year — $13,809 per case. The estimate and its assumptions are in Disease burden.

Who funds it, FY2025

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

2,382 human GEO series match glioblastoma. Keyword relevance cannot tell a 804-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 1220-study ranked set

Sources: NCBI GEO + Europe PMC + iCite, retrieved 2026-09-19. SubSeries are collapsed to one row per study by linked PMID. Of 2,382 series retrieved, 77 were dropped by the profile’s exclusion rules and 766 named the disease only in passing. 1 further series named in the profile as contamination are excluded here. 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.
