Draft for MVP—review with counsel before production use.
Trial Changelog tracks clinical trial updates and highlights material changes. It is a monitoring tool—not investment or medical advice.

Start with a watchlist
Add portfolio and competitor tickers to focus the feed. Watchlists keep daily review tight and reduce noise.
Read the digest
- Event: the type of change (status, outcomes, dates, enrollment).
- Subtype: a compact signal (swap, removed, filled, slip).
- Score/Label: materiality based on severity + context.
- Details: human-readable change summary.
- Scoring: the rule and multiplier used.
Source badges indicate CT.gov→CT.gov (higher confidence) vs cross-source comparisons.

Materiality scoring
High/Medium/Low/Noise are heuristic signals. Use them to prioritize, then verify against primary sources.
Common workflows
- Daily scan: 10 minutes on High/Medium events.
- Weekly review: identify emerging status or outcome trends.
- Termination triage: filter to TERMINATED and review why-stopped.
Limitations
Updates may lag source publication. Cross-source differences may be incomplete. Always verify on CT.gov and other primary sources.
