ClinicalTrials.gov Is a Registry. DataLookout Is a Monitor.
ClinicalTrials.gov stores trial records. It doesn't track changes, send alerts, or tell you when something important happens. DataLookout does.

ClinicalTrials.gov is essential — but not enough
ClinicalTrials.gov is the authoritative source for clinical trial data. Every trial registered in the US is there. But it was built as a registry, not a monitoring tool.
If you search for a trial today, you see its current state. If enrollment changed yesterday from 500 to 700, you'd never know. If a primary endpoint was modified, there's no diff view. If 17 new sites opened in a competitor's Phase 3, there's no alert.
This is the gap DataLookout fills.
What DataLookout adds on top of ClinicalTrials.gov
- Daily change detection — DataLookout fetches from ClinicalTrials.gov every day and compares against yesterday's snapshot. Any field-level change is detected and recorded.
- Severity classification — Status changes and endpoint modifications are flagged as critical. Site expansions as notable. Arm count changes as minor. You see what matters first.
- Change history timeline — Every detected change is stored with before/after values, timestamps, and severity. You get a full audit trail.
- Watchlists — Track specific sponsors or diseases. See all their changes in one place instead of searching manually.
- Consolidated search — ClinicalTrials.gov lists Pfizer, Pfizer Inc., Pfizer Inc, and Pfizer Pharmaceuticals as separate sponsors. DataLookout consolidates them.
