Answer block

12 genes recurrently implicated in gallbladder cancer — ERBB2, TP53, KRAS, PIK3CA, CDKN2A, ARID1A, ERBB3, EGFR, CTNNB1, SMAD4, FGFR2, IDH1 — 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.

3
drugs carry an FDA label naming gallbladder cancer: Durvalumab, Pembrolizumab, Zanidatamab. This counts labels, not treatment — the disease is also treated with agents approved under broader indications
1
of the 12 genes above carry a drug that is approved in gallbladder cancer itself — ERBB2. Across all of them 227 drug entries reach these genes, 212 distinct once salt forms are merged
1
registered HER2 cell-therapy trials in gallbladder cancer, 1 active. Counted from ClinicalTrials.gov across 9 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
6
targets carry an Open Targets tractability signal and have no clinical programme of any kind: TP53, KRAS, ARID1A, CTNNB1, SMAD4, IDH1. ERBB2, ERBB3 have cell-therapy trials, so they are undrugged rather than untouched
53
human GEO series match the disease; 24 survive on-topic filtering, and only 0 are patient cohorts of 100+ samples
27
Europe PMC full-text papers name GSE139682 — the highest accession-mention count in the set. A mention is not proof of reanalysis, so read it as reach rather than reuse

NIH obligations in FY2025, up -100% since 2013 — while distinct core projects went 1 to 0. Larger awards rather than more distinct core projects; core projects are not the same unit as laboratories

Target landscape

Open Targets · retrieved 2026-09-16 · weekly

12 genes recurrently implicated in gallbladder cancer, triaged for whether anything can actually be aimed at them. The zeros are the informative rows.

Of 12 recurrently implicated genes, 9 carry any drug at all. That is a statement about these 12 gene targets, not about the disease: Gallbladder cancer does have labelled therapy — 3 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 gallbladder cancer 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 HER2

ClinicalTrials.gov · retrieved 2026-09-16 · weekly

HER2 is the busiest cell-therapy antigen in gallbladder cancer: 1 registered trials, 1 still active. It has no gene entry of its own and is reached through ERBB2: the receptor HER2 encodes, amplified in about one gallbladder cancer in six -- more often than in any other biliary site -- and the target of zanidatamab, approved for HER2-positive biliary tract cancer.

Public datasets, ranked

NCBI GEO + Europe PMC + iCite · weekly

53 human GEO series match gallbladder cancer. Keyword relevance cannot tell a 56-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.

Sources: NCBI GEO + Europe PMC + iCite, retrieved 2026-09-16. SubSeries are collapsed to one row per study by linked PMID. Of 53 series retrieved, 4 were dropped by the profile’s exclusion rules and 20 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.

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.

KRAS

2 approved drugs (Adagrasib, Sotorasib) and no registered trial in gallbladder cancer. The molecules exist; nobody has tested them here.

CDKN2A

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

ARID1A

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

SMAD4

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

IDH1

3 approved drugs (Ivosidenib, Olutasidenib, Vorasidenib) and no registered trial in gallbladder cancer. 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 (2026-09-16), ClinicalTrials.gov (2026-09-16), openFDA (2026-09-16), NCBI GEO (2026-09-16), PubMed (2026-09-16), NIH RePORTER (2026-09-16).

Negatives stated explicitly

Where nothing exists for gallbladder cancer — 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 note is used as a model system in gallbladder cancer. What was removed and why is stated in each section rather than silently applied.
