# How to Verify a Startup's FDA Claims During Due Diligence: A Step-by-Step Guide for Healthcare Investors > Verifying a startup's FDA claims requires cross-referencing primary government databases, regulatory filings, and clinical records before committing capital. This guide walks healthcare investors through exactly which sources to check, what red flags to look for, and how to avoid the most costly due-diligence mistakes. ## Why FDA Claim Verification Is the Most Critical Step in Healthcare Due Diligence FDA claims are the single most common source of material misrepresentation in early-stage healthcare investing. Founders routinely overstate clearance status, conflate regulatory pathways, or describe ongoing submissions as completed approvals. A disciplined investor verifies every FDA-related assertion against primary government sources before any capital commitment. The process is methodical and entirely doable with public tools, but it requires knowing exactly where to look and what discrepancies to flag. ## What Are the Primary FDA Databases You Must Check First Start with the official FDA databases. These are free, public, and authoritative. **510(k) Premarket Notifications:** Search the FDA 510(k) database at accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm. Enter the company name or device name and confirm the K-number, clearance date, device classification, and predicate device. A legitimate 510(k) clearance produces a decision letter you can read in full. **PMA (Premarket Approval):** For Class III devices, search the PMA database at accessdata.fda.gov/scripts/cdrh/cfdocs/cfpma/pma.cfm. Verify the approval date, any post-approval study requirements, and supplement history. Unapproved supplements can restrict the commercial use the company claims. **De Novo Pathway:** Check the De Novo database if the startup claims this pathway, since founders sometimes confuse De Novo grants with full PMA approvals. They carry different commercial implications. **Drug Approvals (NDA/BLA/ANDA):** Use Drugs@FDA at accessdata.fda.gov/scripts/cder/daf/ to confirm NDAs, BLAs, and ANDA approvals. Pull the full approval letter and review any REMS requirements or labeling restrictions that could limit the market the startup is projecting. **FDA Establishment Registration and Device Listing:** Search accessdata.fda.gov/scripts/cdrh/cfdocs/cfRL/rl.cfm to confirm the company's manufacturing establishment is registered and the device is listed. An unlisted device being sold commercially is a serious compliance red flag. ## How Do You Verify FDA Claims in Investor Decks Against Public Records Many founders describe regulatory status inaccurately, sometimes through honest confusion and sometimes through intentional stretching. Here is how to cross-reference their specific claims. 1. **Ask for the exact K-number, PMA number, or NDA number** in writing. No legitimate FDA clearance or approval exists without a document number you can verify independently. 2. **Compare the cleared indications** in the FDA decision letter with the intended use the startup is marketing. 510(k) clearances are often narrow; a company may be cleared for one indication but pitching a broader clinical application. 3. **Check the FDA Warning Letter database** at accessdata.fda.gov/scripts/warningletters/. Search by company name and look for any correspondence about unapproved claims, manufacturing violations, or GMP deficiencies within the last five years. 4. **Search the FDA 483 Inspection Database and Establishment Inspection Reports** through FOIAonline or the FDA FOIA Reading Room. Repeat 483 observations on the same issue across multiple inspections signal systemic quality failures. 5. **Review the FDA Recall Database** at accessdata.fda.gov/scripts/cdrh/cfdocs/cfres/res.cfm. Even a Class II or III recall in the company's history changes the risk calculus significantly. ## What Should You Check on ClinicalTrials.gov to Validate Regulatory Claims The startup's claimed trial results must match what ClinicalTrials.gov actually shows. Go to clinicaltrials.gov and search by company name, device name, or NCT number provided in the pitch materials. Verify the trial phase, enrollment numbers, primary endpoints, and completion dates. A company claiming Phase 3 results from a trial the registry shows as Phase 2 is misrepresenting clinical evidence. Also check whether results have been posted in the registry within the required 12-month window, since missing results reporting is itself a compliance violation. Cross-reference published outcomes on PubMed (pubmed.ncbi.nlm.nih.gov) to confirm the data behind any efficacy claims. ## How Do You Assess Patent and IP Claims That Support FDA Exclusivity Arguments Startups often tie their regulatory moat to patent protection. Verify on Google Patents or the USPTO Patent Full-Text Database (patents.google.com or ppubs.uspto.gov). Confirm the patent is granted (not just applied for), check the expiration date accounting for maintenance fees, and review the independent claims to see whether they actually cover the commercialized product. For drug companies, also check the FDA Orange Book (accessdata.fda.gov/scripts/cder/ob/) to confirm which patents are listed and their expiration dates. ## What Are the Most Common Red Flags That Signal FDA Claim Misrepresentation Watch for these warning signs across all your primary source checks. - Clearance or approval claimed for a product that returns no results in FDA databases - FDA clearance letter indications that are narrower than the marketed use - Active Warning Letters or consent decrees the company did not disclose - Clinical trial registrations showing different endpoints than those cited in the pitch deck - Establishment registration that expired or was never completed - Patents that are pending applications rather than granted claims - Phase designations in pitch materials that do not match the ClinicalTrials.gov record ## Quick Verification Checklist for Healthcare Investors - [ ] Confirmed K-number, PMA number, or NDA/BLA number in FDA database with matching clearance letter - [ ] Compared cleared indications with marketed use for scope alignment - [ ] Searched FDA Warning Letter and recall databases by company name - [ ] Reviewed 510(k) predicate chain or PMA post-approval requirements - [ ] Verified ClinicalTrials.gov registration matches claimed phase, endpoints, and enrollment - [ ] Cross-checked published results on PubMed against investor deck efficacy claims - [ ] Confirmed establishment registration is current - [ ] Verified granted patent claims (not applications) cover the commercialized product - [ ] Checked SEC EDGAR filings (edgar.sec.gov) for any material FDA risk disclosures if the company has prior public filings ## How MedFuel Intel Automates This Process MedFuel Intel built its AI due-diligence platform specifically to run every one of these checks in minutes rather than days.
