12 genes recurrently implicated in mesothelioma — BAP1, CDKN2A, NF2, TP53, SETD2, LATS2, MSLN, CD274, PDCD1, CTLA4, VEGFA, ALK — triaged for what can actually be aimed at them, alongside the trials, public datasets, literature and funding around the disease. Every figure below carries its source and retrieval date in the section it comes from.

4
drugs carry an FDA label naming mesothelioma: Ipilimumab, Nivolumab, Pembrolizumab, Pemetrexed. This counts labels, not treatment — the disease is also treated with agents approved under broader indications
2
of the 12 genes above carry a drug that is approved in mesothelioma itself — CTLA4, PDCD1. Across all of them 85 drug entries reach these genes, 82 distinct once salt forms are merged
12
registered mesothelin cell-therapy trials in mesothelioma, 6 active. Counted from ClinicalTrials.gov across 6 synonyms, deduplicated by NCT id, interventional studies only — the query is published in the JSON beside this page so the number can be re-derived
5
targets carry an Open Targets tractability signal and have no clinical programme of any kind: BAP1, NF2, SETD2, LATS2, ALK. MSLN, PDCD1 have cell-therapy trials, so they are undrugged rather than untouched
195
human GEO series match the disease; 95 survive on-topic filtering, and only 1 are patient cohorts of 100+ samples

Target landscape

Open Targets · retrieved 2026-09-12 · weekly

12 genes recurrently implicated in mesothelioma, 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: Mesothelioma does have labelled therapy — 4 drugs, listed in the next section.

Two different questions

The table below asks what can be aimed at 12 recurrently implicated genes. That is narrower than what is approved for the disease, and narrower again than what mesothelioma is actually treated with, which includes agents approved under broader indications. All three are on this page and they are kept apart deliberately.

Cell therapy against mesothelin

ClinicalTrials.gov · retrieved 2026-09-12 · weekly

mesothelin is the busiest cell-therapy antigen in mesothelioma: 12 registered trials, 6 still active. It has no gene entry of its own and is reached through MSLN: the surface glycoprotein MSLN encodes, mesothelin, named for this tumour and expressed by almost all of the epithelioid form; every antibody, ADC and CAR against it was tested here first.

195 human GEO series match mesothelioma. Keyword relevance cannot tell a 120-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.

The ranked set is a relevance-ranked sample, not a census, so the composition figures describe the sample only.

Where the gaps are

Derived from the sections above · recomputed on every refresh

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.

BAP1

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

CDKN2A

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

NF2

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

TP53

1 registered trial, 1 withdrawn before enrolling anyone and none active. This target reads as tried; it was not.

SETD2

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

LATS2

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

MSLN

12 cell-therapy trials against mesothelin, 6 active, and no approved product. The clinical activity is real and none of it has reached a label.

ALK

6 approved drugs (Alectinib, Brigatinib, Ceritinib) and no registered trial in mesothelioma. The molecules exist; nobody has tested them here.

How a machine reads this page

Static

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.

Fully server-rendered

Every figure is in the HTML at first byte. No JavaScript runs, no figure is fetched after load, and nothing on this page requires a renderer to see.

Every number carries a source

Each section names the API it came from and the date it was retrieved: Open Targets (2026-09-12), ClinicalTrials.gov (2026-09-12), openFDA (2026-09-12), NCBI GEO (2026-09-12), PubMed (2026-09-12), NIH RePORTER (2026-09-12).

Negatives stated explicitly

Where nothing exists for mesothelioma — no drug, no trial, no approval — the page says so in those words rather than omitting the row. An absent row is unquotable; a stated negative is the finding.

Denominators, not just percentages

Every share is printed with the count and the total it came from, so a figure can be checked rather than taken.

The filters are published

4 exclusion patterns are applied to free text before anything is ranked, because none of consequence is used as a model system in none: the mesothelioma lines are used for the disease. What was removed and why is stated in each section rather than silently applied.
