ClinicalTrials.gov has the data. The default search UI does not have the patience. This skill puts a natural-language layer on top so you can ask “phase 2 ulcerative colitis trials with biologics-naïve patients enrolled since 2023” and get results, instead of clicking through six refinement panels.

What it does

Semantic search over the ClinicalTrials.gov registry: trial identifiers, enrollment criteria, sponsors, phase, primary outcomes, completion status. Useful when you need to scan competitive landscape, prep for a regulatory filing, or sanity-check a trial-design assumption.

Who it’s for

Industry-track PhDs and postdocs moving into clinical research, biostatistics, regulatory affairs, or biotech competitive intelligence
Anyone designing a trial who needs to know what’s already running
Investor-side professionals doing diligence on a biotech pipeline
Early-career scientists transitioning from preclinical to clinical work who don’t yet have a refined search vocabulary

What to watch for

Selection bias toward US-registered trials. EU CTR and ChiCTR have separate registries with different completeness profiles
Status fields lag. A trial marked “recruiting” may have completed enrollment without the registry being updated
Natural language is not a substitute for structured filtering when you need an exhaustive list. For systematic competitive landscape work, run the structured filter once you know what you’re looking for.

Verdict

A solid first-pass tool for scanning ClinicalTrials.gov when you don’t already know exactly what you want to find. Pair it with the structured search UI for the final, exhaustive pull.
