Small cell lung cancer: research and therapeutic landscape

Answer block

12 genes recurrently implicated in small cell lung cancer — DLL3, TP53, RB1, MYC, MYCL, ASCL1, NEUROD1, POU2F3, YAP1, SLFN11, BCL2, CD274 — 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 small cell lung cancer: Atezolizumab, Durvalumab, Lurbinectedin, Tarlatamab. 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 small cell lung cancer itself — CD274, DLL3. Across all of them 31 drug entries reach these genes, 28 distinct once salt forms are merged
9
registered DLL3 cell-therapy trials in small cell lung cancer, 8 active. Counted from ClinicalTrials.gov across 8 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: RB1, MYC, POU2F3, YAP1, SLFN11. DLL3, CD274 have cell-therapy trials, so they are undrugged rather than untouched
549
human GEO series match the disease; 214 survive on-topic filtering, and only 2 are patient cohorts of 100+ samples
119
Europe PMC full-text papers name GSE60052 — the highest accession-mention count in the set. A mention is not proof of reanalysis, so read it as reach rather than reuse
$38.6M
NIH obligations in FY2025, up 1743% since 2013 — while distinct core projects went 9 to 60. 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 small cell lung cancer, triaged for whether anything can actually be aimed at them. The zeros are the informative rows.

Of 12 recurrently implicated genes, 4 carry any drug at all. That is a statement about these 12 gene targets, not about the disease: Small cell lung cancer 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 small cell lung cancer is actually treated with, which includes agents approved under broader indications. All three are on this page and they are kept apart deliberately.

Years of life lost

6.7 years per case, 200,828 a year, from survival and age at diagnosis rather than from a death count. derived proxy What this costs to fund is in Funding.

3 assumptions behind this estimate
  • Five-year relative survival stands in for cure; a death after five years is not counted.
  • The median age at diagnosis stands in for the whole age distribution.
  • Life expectancy at birth (78.4 years) is the reference, rather than remaining expectancy at the age of death from a life table.
  • Each assumption moves the result by more than the difference between the two diseases currently on this site, so this figure separates a disease from one ten times its size, not from a close neighbour.

Keyword relevance cannot tell a 375-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.

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.

TP53

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

RB1

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

MYC

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

MYCL

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 small cell lung 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

5 exclusion patterns are applied to free text before anything is ranked, because NCI-H69 (a generic neuroendocrine model) is used as a model system in neuroendocrine differentiation and drug-transport studies. What was removed and why is stated in each section rather than silently applied.
