How do you prepare Forms FDA 3454 and 3455?
First identify covered studies and reconcile their investigators, sponsor relationships and financial information. Select the applicable certification or disclosure from documented facts; unresolved information needs a supported disposition. Match forms and attachments to that roster, describe actual measures addressing potential bias, and obtain review and execution by the responsible applicant official.
Before you begin
Marketing applications containing covered clinical studies under 21 CFR Part 54. IND-stage information collection supports later disclosure; it is not the same filing trigger.
What you will prepare: An investigator reconciliation and evidence-supported form package ready for authorized execution.
Define the studies and people before selecting a form
A covered study is determined by its role in the marketing application, using §54.2(e), not simply its phase label. The rule covers studies relied on for effectiveness, including equivalence, and studies in which a single investigator makes a significant safety contribution. Record the rationale for each study’s disposition.
Build a roster of investigators and subinvestigators directly involved in treatment or evaluation, identify sponsor employees and account for the defined spouse/dependent-child interests. Reconcile names and study IDs with the clinical reports and investigator records. Do not indiscriminately count every laboratory employee or silently omit a covered investigator because a form is missing.
Choose the certification or disclosure from confirmed facts
Form 3454 supports the applicable certification; Form 3455 discloses reportable interests/arrangements and steps taken to minimize bias. Part 54 also provides a due-diligence certification when the applicant tried but could not obtain information, with the reason. “No response” is not “no financial interest.” Use the appropriate current form option and supporting explanation.
Check product/application identity, study scope, investigator attachments, selected statement and responsible corporate official’s signature/date. Where a certification covers less than all covered clinical data, identify the studies it covers. For a disclosure, describe the nature of the interest and the actual bias controls, rather than asserting “no effect on results” without an analysis.
Apply the correct financial category and period
Section 54.2 distinguishes outcome-dependent compensation, proprietary interests, significant equity and significant payments of other sorts. Its publicly traded equity threshold is more than $50,000; interests whose value cannot readily be determined from public prices have a different definition. Significant other payments exceed $25,000 and exclude the costs of conducting the clinical studies. The relevant definitions and update duty extend through one year after study completion.
Have the financial-information owner apply those definitions to the actual arrangement. Do not apply the publicly traded threshold to private-company equity, or use a payment amount alone without determining what it paid for.
Worked check: private equity and a missing response
Fictional exercise: Investigator A holds private-company options; Investigator B has not answered repeated documented requests. Do not clear A by comparing the options with the public-equity threshold. For B, retain the actual attempts, investigate alternate sources and have the responsible owner determine whether the due-diligence statement is supportable.
Change the scenario to a study not relied on for effectiveness and with no significant single-investigator safety contribution: reassess covered-study status from §54.2(e), not from the mere existence of a CSR. Missing study-purpose information leaves coverage undetermined.
Reconcile people, interests and supporting attachments
Build one working row for each relevant investigator–study relationship. An investigator may appear in more than one study, and the sponsor or financial arrangement may differ. This internal table helps review the package; it is not a substitute for an FDA form.
| Review field | Evidence to record | Question before finalizing |
|---|---|---|
| Study coverage | Study ID and its role in the application | Why is this a covered study under Part 54? |
| Investigator identity | Name, role, site and study participation | Does the roster reconcile with the submitted clinical records? |
| Sponsor relationship | Sponsor of that study and employee status | Is employment being assessed against the correct sponsor? |
| Interests and arrangements | Category, period and underlying response or record | Have spouse/dependent-child interests and different category definitions been addressed? |
| Disposition | Certification, disclosure or unresolved information | Does the selected statement match the evidence? |
| Attachments | Investigator list, details, bias measures or inability explanation | Can a reviewer trace every row to its final destination? |
Keep identified sponsor employees in the roster; do not make them disappear when determining the applicable certification/disclosure population. For everyone requiring a disposition, record the source of the information and its covered period. An undated questionnaire can leave a timing gap even when every box is checked.
Payment exercise: an institution’s invoice combines study-conduct costs with payment for separate consulting work. Ask the financial owner to identify the activities and applicable categories before applying a threshold. Treating the entire invoice as either routine study costs or reportable other payments can produce the wrong conclusion. Preserve the category analysis supporting the final answer.
For a missing response, keep the actual contact attempts and review other reasonably available reliable information. FDA’s guidance describes reasonable efforts using more than one contact method in most cases; it does not create an automatic clearance after a fixed number of emails.
The official forms inspected October 6, 2026 have 2/26 and 4/26 footers for 3454 and 3455 respectively. Both display July 31, 2028 as the OMB expiration date. Reconcile application identity with Form 356h and the final attachment map with the submission reviewer guide.

Frequently asked questions
Can an unanswered financial questionnaire support a no-interest certification?
No. Silence does not establish the absence of reportable arrangements. Document reasonable attempts and review other available information. Where information still cannot be obtained despite due diligence, use the applicable certification and explanation process based on those actual efforts, rather than converting an unknown into a negative answer.
Does the $50,000 public-equity threshold apply to private-company options?
No. Part 54 distinguishes publicly priced equity from interests whose value cannot readily be determined from public prices. Do not clear private-company options by comparing a guessed value with the public-equity threshold. Identify the arrangement and apply its own definition with the financial-information owner.
Must each investigator sign Form 3454 or Form 3455?
The investigator supplies accurate financial information to the study sponsor. The applicant submits the certification or disclosure package; the forms provide for execution by the responsible applicant official or representative. An investigator’s questionnaire supports that work but is not interchangeable with the applicant’s executed submission form.
Does disclosing a financial interest automatically invalidate the study?
No. FDA evaluates the interest in context, including the study’s design and measures taken to minimize bias. Describe the actual safeguards and relevant evidence. Neither the presence of an interest nor a bare assertion that it had no effect resolves the reliability assessment by itself.
Does the financial-information period end when an investigator leaves the study?
Do not use departure alone as the cutoff. The regulation requires relevant updates during the investigation and for one year after study completion. FDA’s guidance explains completion in relation to the part of the study supporting the application; document that basis rather than substituting the investigator’s last working day.
