trial_searcher
Search ClinicalTrials.gov for clinical trials by conditions, interventions, location, phase, and eligibility. Filter results efficiently using geolocation, recruiting status, and study type. Returns detailed trial information for medical research.
Instructions
Search ClinicalTrials.gov for clinical studies.
⚠️ PREREQUISITE: Use the 'think' tool FIRST to plan your research strategy!
Comprehensive search tool for finding clinical trials based on multiple criteria.
Supports filtering by conditions, interventions, location, phase, and eligibility.
Location search notes:
- Use either location term OR lat/long coordinates, not both
- For city-based searches, AI agents should geocode to lat/long first
- Distance parameter only works with lat/long coordinates
Returns a formatted list of matching trials with key details.
