Change Detection

What gets caught.

ClinicalTrials.gov logs every update but doesn't surface them. We run a daily comparison and categorize every change.

Endpoint

Endpoint Modifications

Primary and secondary endpoint changes, outcome measures added or removed, assessment timepoints shifted.

Enrollment

Enrollment Changes

Target enrollment updated, eligibility criteria modified, new sites added, age range or inclusion/exclusion criteria changed.

Status

Status Shifts

Recruiting, suspended, terminated, completed. Caught the day the registry updates. Stopped trials flagged immediately.

Study Arm

Study Arms

Arms added or dropped, dosing changes, new intervention branches, comparator updates across multi-arm studies.

Company Pipeline View
