Clinical trial desk · $49/month
Follow 25 trials. See when they move.
Search is free. Monitor is $49 a month. Your desk stores the last status, dates, and enrollment, then marks Changed when those fields move. Open the ClinicalTrials.gov record from the card.
How to use it

Watch the desk
You see stored values first. Changed appears after status, dates, or enrollment move. No email.
What you get
Use it when you need to know whether a trial you already follow changed status, dates, or enrollment. You check the desk. You open the registry record. That is the product.

Who this is for
Consultants
A brief a client can audit
What moved, the primary record, and the caveat. Not a curated pipeline database.
Small biotech and BD
Competitor timing without a contract
Watch Phase 2/3 industry programs and status reversals on a Monday morning email once you save a watchlist.
Specialist journalists
Public-record changes worth a call
Terminations, date slips, recalls, and FDA communications with a link to the source page.
What a signal looks like
Illustrative examples — not live records
Example signals. The cards below describe the shape of a signal from each source. Real signals on /trials, /safety, and /sponsors link directly to the primary public record.
Trial Movement
Example signal
Notable
Phase 3 GLP-1 obesity program — primary completion shifted
GLP-1 drug class · Phase 3 · Condition: Obesity
What changed. Registry record updated — primary completion moved later. Why it matters. Read-out timing shifts cascade through competitor positioning and analyst submission-timeline models.
Source type: ClinicalTrials.gov registry record
Fields surfaced: status, primary completion date, last update posted
FDA / Safety
Example signal
High Attention
openFDA Drug Enforcement — Class II recall posted
openFDA Drug Enforcement · Recall class: II · Multiple lots
What changed. A Class II recall covering multiple lots was entered into openFDA enforcement records. Why it matters. Class II indicates temporary or reversible health consequences are possible; supply chains and prescribers track these closely.
Source type: openFDA Drug Enforcement endpoint
Fields surfaced: classification, recall reason, lots, distribution pattern, status
Sponsor Disclosure
Example signal
Monitor
Public biotech sponsor — Form 8-K references FDA correspondence on Phase 2 program
SEC 8-K disclosure · Phase 2 oncology program · Sponsor-disclosed
What changed. A material-event filing reports receipt of FDA correspondence regarding the sponsor's Phase 2 program. Why it matters. Sponsor-disclosed FDA correspondence often precedes registry status changes by days to weeks.
Source type: SEC EDGAR Form 8-K filing
Fields surfaced: item, filing date, narrative excerpt with FDA-correspondence reference
Live trial movement
ClinicalTrials.gov · Last checked moments ago
Updated vs changed. A last-update date is not a field diff. Cards labeled Changed show previous and new values. Cards labeled Updated only have the current registry state.
Evidence Room
Every signal traces back to a primary public record
Every record we ship carries the same source-backed contract — the fields a researcher needs to verify, cite, and re-audit. If a field can't be filled from the primary record, the signal does not ship.

AI-assisted interpretationA 6-month shift on a lead Phase 3 read-out moves the sponsor's regulatory submission window out of 2026, with downstream implications for competing-program timing and BD windows. Driver not disclosed in the registry record.
Registry date moves do not establish cause. Possible drivers include enrollment, supply, protocol amendments, analytical plan changes, or safety review. The sponsor has not publicly disclosed a reason in the registry record.
Why not enterprise platforms?
Clinical Trial Signal is not a proprietary curated enterprise database. It is a lower-cost public-record movement layer — built to detect what changed in public sources, generate source-backed briefs you can hand to a colleague or client, and tell you where deeper, paid-database research is actually worth the effort. Enterprise platforms still own deep curated pipeline / patent / regulatory / deal datasets; we sit beside them as an awareness layer, not a replacement.

Compliance-safe positioning. Clinical Trial Signal provides public-data research intelligence. It is not medical advice, legal advice, regulatory advice, investment advice, or a pharmacovigilance system of record. Public adverse-event data may be incomplete, duplicated, unverified, and cannot establish causation or incidence. Signals are intended for research screening and should be reviewed by qualified professionals.
