01 / Why RegPharma

The first public CRL archive

FDA started publishing Complete Response Letters in September 2025 under its radical-transparency policy. We index every one, link to FDA's source, and alert you when a sponsor on your watchlist receives one. Cortellis, Citeline, and Redica all consume the same feed — we're the only ones publishing it.

Event monitoring, not research

Rhizome AI answers “what does FDA think about X?” We answer “what just happened to a biotech I'm tracking?” Different work; we're complementary, not competing. Use both if it helps.

Honest coverage, every alert

Every alert footer states our source explicitly with a direct link to FDA. CRL lag is ~3 weeks behind FDA publication; warning letters ~8 days — we don't pretend to be faster than the source. When clinical-hold alerts ship in v1.1, every alert will disclose the ~70–80% coverage limit explicitly. No “we cover everything.”

02 / Coverage

What we monitor

Two live feeds at launch; three more rolling out in the weeks after. Source, freshness, and coverage are disclosed on every row — and on every alert.

Not in v1 or v1.1: 483 inspection observations. These require FOIA workflows that we'd compete with Redica on — and Redica has a 5-year head start. We may surface adjacent inspection signals later; we'll be transparent about coverage when we do.

03 / Positioning

How we're different

We don't compete with the enterprise databases or with research assistants. We sit in a different lane: cheap, fast event monitoring on the watchlist your RA team already maintains.

05 / Trust

Trust & transparency

Four standing commitments about how we source, label, and scope what we sell.

  • Sources are public. Every alert links to FDA's source URL (openFDA, FDA datatables, SEC EDGAR). We're a UI on top of public data, not a proprietary intelligence service.
  • Coverage is disclosed. CRL lag is ~3 weeks behind FDA publication; warning letters ~8 days. When clinical-hold alerts ship in v1.1, every alert will name the ~70–80% coverage limit. We don't pretend to be faster than the source.
  • Informational, not advisory. Our alerts inform your team's regulatory decisions. They are not a substitute for professional judgment, legal review, or FDA submissions strategy.
  • Not for trading. PDUFA, AdComm, and clinical-hold events can move biotech stocks. Our alerts are intended for RA teams doing regulatory work, not investment decisions. We do not provide investment advice.

06 / FAQ

Frequently asked

What is a Complete Response Letter?

A CRL is FDA's formal response when it cannot approve an NDA or BLA in its current form, citing specific deficiencies. Before September 2025, CRLs were not public — sponsors received them privately. Under FDA's radical-transparency policy, all CRLs are now published via openFDA.

How do you cover clinical holds?

Clinical holds are not proactively published by FDA. We surface them via (a) SEC EDGAR 8-K filings for public companies (real-time) and (b) press-wire monitoring for private companies that voluntarily disclose. Coverage: ~70–80%. Every clinical-hold alert footer states this explicitly. We never claim “all” clinical holds.

How are you different from Rhizome AI?

Rhizome answers regulatory questions with citations from a 2.5TB corpus. We monitor FDA's event feeds and route them to your watchlist. Different jobs — many RA teams will want both. We're not a substitute.

How are you different from Cortellis / Citeline?

They sell comprehensive enterprise platforms with workflow + expert summaries at $20K–$200K+/yr. We sell event monitoring for the watchlist you specify at $249–$499/mo. Smaller scope; smaller price; faster to start.

Do you give regulatory advice?

No. We are an informational service. Our alerts surface FDA-published data. They do not constitute regulatory, legal, or investment advice.

Can I trade on your alerts?

Our service is not designed or licensed for use in investment decisions. PDUFA / AdComm / CRL alerts can move biotech stocks; we are not a financial-data service and you should not rely on us for trading decisions.

Why the $249 price?

Self-serve, no procurement friction, fits the “tools & subscriptions” budget at most Series B/C biotechs. We grandfather the first 50 customers at this price for 24 months even when we change public pricing.
