How this service works
Search ClinicalTrials.gov by condition, drug/device or sponsor: status, phase, enrollment, start and completion dates, sponsor, interventions and countries. Use for pharma, biotech and patient research.
Output
Returns a list of matching clinical trials from ClinicalTrials.gov, each including trial status, phase, enrollment count, start and completion dates, sponsor name, interventions (drugs/devices), and countries where the trial is conducted.
Example use cases
Patient finding trials for their diagnosis
“Can you search for currently recruiting clinical trials for non-small cell lung cancer? Show me up to 10 results so I can see what's available.”
Pharma competitive intelligence
“Look up all completed phase 3 trials sponsored by Pfizer for cardiovascular conditions — I want to see up to 25 results to understand their pipeline history.”
Biotech drug pipeline research
“Find me active phase 1 and phase 2 trials involving the drug semaglutide for diabetes — limit to 15 results — so I can track its clinical development progress.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/health/clinical-trials?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, filterable clinical trial data from ClinicalTrials.gov without building your own integration. It is ideal for pharma/biotech competitive intelligence, patient advocacy research, drug pipeline analysis, and academic research requiring trial metadata by condition, intervention, sponsor, phase, or status. Prefer this over direct ClinicalTrials.gov scraping for agent workflows needing clean, structured JSON output.
Side effects
- No trials found matching the given condition/sponsor/intervention combination — returns empty results
- Invalid phase value (not one of: 1, 2, 3, 4, early1) — may return error or empty results
- Invalid status value (not one of: recruiting, active, completed, not_yet_recruiting, terminated, withdrawn) — may return error
- Limit out of range (must be 1-50) — may return validation error
- ClinicalTrials.gov upstream API unavailable — service returns error
- Overly broad query returning too many results — use limit parameter to cap output
