Clinical Trial Tracker

Search and monitor clinical trials from ClinicalTrials.gov. Filter by disease, drug, sponsor, phase, and recruitment status. Returns structured data including interventions, eligibility criteria, enrollment, locations, and outcomes. No API key required.

What it extracts

Per trial:

• NCT ID, title, official title, direct URL
• Overall status (Recruiting, Completed, Terminated, etc.)
• Study type and phase (1-4)
• Lead sponsor and collaborators
• Conditions and keywords
• Interventions (drugs, devices, procedures) with descriptions
• Enrollment count and type (estimated/actual)
• Start date, completion date, last updated
• Brief summary
• Eligibility criteria (age, sex, healthy volunteers, inclusion/exclusion)
• Study locations (facility, city, state, country)
• Primary and secondary outcome measures
• Whether results have been posted

Use cases

• Competitive intelligence — track competitor drug pipelines by sponsor
• Investment research — monitor Phase 3 trials for biotech due diligence
• Patient recruitment — find recruiting trials by condition and location
• Academic research — bulk download trial metadata for analysis
• Regulatory monitoring — track status changes across a therapeutic area
• Market analysis — map the clinical landscape for a disease area
