Quick answer
- No fixed two-year rule: FDA regulations do not require a CV or statement of qualifications to be updated on a two-year cycle, or at any set interval, during a clinical study.
- Qualifications still must be documented: Good Clinical Practice requires that the investigator be qualified by education, training, and experience, and that this be evidenced in the trial record.
- Sponsors can set their own standard: a sponsor may require periodic CV updates as part of its quality system, and sites should follow those requirements.
- Stale qualifications create risk: if a CV is more than two years old, the necessary evidence of current qualifications may be lacking when an inspector asks.
The Short Answer
No. FDA regulations do not require a CV or other statement of qualifications to be updated during a clinical study. However, a sponsor may require CV updates. In addition, the regulations DO require that you have the necessary education and experience to perform your job. If your CV is more than two years old, the necessary evidence may be lacking. USDM Life Sciences recommends you adhere to sponsor requirements that are provided during the trial.
What the FDA Guidance Actually Says
According to page 11 of the Information Sheet Guidance for Sponsors, Clinical Investigators, and IRBs, “Section #2 requires the investigator to attach a curriculum vitae (CV) or other statement of qualifications, showing the education, training and experience that qualifies the investigator as an expert in the clinical investigation of the drug/biologic for the use under investigation. Information identified in this section should be attached to Form 1572 which enables the sponsor to assess an investigator’s qualifications.” Form 1572 is required to be updated if the investigator is added to another protocol in the study. For additional information, reference the information sheet.
The key point is that the obligation is tied to qualifications and to the accuracy of Form FDA 1572 (the Statement of Investigator), not to a calendar. There is no regulatory clock that says a CV expires after a fixed number of months or years. What the rules care about is whether the documentation on file still supports the investigator’s ability to conduct the specific investigation under the specific protocol.
Where the Requirement Comes From
For studies conducted under an Investigational New Drug application, the investigator’s qualification obligation is grounded in U.S. regulation. Under 21 CFR Part 312, sponsors are responsible for selecting qualified investigators, and the investigator commits, on Form FDA 1572, to conducting the study in accordance with the protocol and applicable requirements. The CV or equivalent statement of qualifications is the supporting evidence behind that commitment.
Internationally, the same principle is expressed through the ICH E6 Good Clinical Practice guideline. ICH E6 states that an investigator should be qualified by education, training, and experience to assume responsibility for the proper conduct of a trial, and that the qualifications should be documented and available for verification. GCP does not prescribe a renewal interval either — it sets an expectation of current, documented, and verifiable qualifications.
What "documented qualifications" should cover
- Education and credentials: degrees, licensure, board certifications, and other formal qualifications relevant to the investigation.
- Relevant experience: clinical and research experience appropriate to the therapeutic area and the type of study.
- GCP and protocol training: evidence that the investigator and key staff understand GCP and the specific protocol requirements.
- Currency: documentation recent enough that it still reflects the investigator’s present role, training, and experience.
Why the "Two-Year" Habit Exists
Many sponsors and contract research organizations ask sites to refresh CVs on a roughly two-year cadence, and many sites have adopted it as a default. That practice is a quality and risk-management convention, not a regulatory mandate. It exists because a CV is a snapshot in time: people change roles, complete new training, gain therapeutic-area experience, or update licensure. A document that is several years old may no longer reflect the person who is actually running the trial.
From an inspection-readiness standpoint, a periodically refreshed CV is simply easier to defend. When qualification evidence is current and consistent with the rest of the regulatory file, it removes a line of questioning before it starts. When it is stale, it can invite questions about whether the site is keeping its essential documents current more broadly.
Treat the CV as an Essential Document, Not Paperwork
The investigator CV lives alongside the trial master file and the site’s essential documents. Like other essential records, its value depends on being accurate, attributable, and consistent with everything around it. If the CV says one thing and the delegation log, training records, or Form FDA 1572 say another, the inconsistency is the finding — not the age of the document by itself.
This is fundamentally a data integrity question. The expectations that apply to electronic and paper records throughout a trial — that they be accurate, complete, and trustworthy — apply to qualification documentation as well. A current, signed CV that aligns with training and delegation records is part of a defensible, audit-ready picture.
Practical Recommendations for Sponsors and Sites
The goal is not to manufacture more paperwork. It is to make sure the qualification evidence on file would survive an inspection without scrambling.
- Follow the sponsor’s requirement first. If the sponsor or CRO specifies a CV refresh interval or format, treat that as the binding standard for the study.
- Refresh when something material changes. A new role, new licensure, relevant new training, or a move to a different therapeutic area is a better trigger than the calendar alone.
- Keep Form FDA 1572 aligned. Update the 1572 when the investigator is added to another protocol in the study, and make sure the attached qualification statement matches.
- Check internal consistency. The CV, delegation log, training records, and licensure should tell the same story about who is qualified to do what.
- Date and sign the document. A CV with a clear, recent date and signature is far easier to defend than an undated one of uncertain vintage.
Modern clinical operations increasingly manage these records in validated electronic systems, where the controls expected under 21 CFR Part 11 apply to the electronic records and signatures involved. Treating qualification documents with the same rigor as other regulated records keeps the whole essential-document set inspection-ready, and a risk-based approach consistent with Computer Software Assurance can focus effort where the compliance impact is highest.

FAQ: Clinical Investigator CV and Qualification Requirements
Does FDA require a clinical investigator CV to be updated every two years?
No. FDA regulations do not require a CV or other statement of qualifications to be updated every two years, or on any fixed interval, during a clinical study. The regulations require that the investigator be qualified by education, training, and experience and that this be documented. A sponsor may impose its own CV update schedule, and sites should follow it.
Where is the CV requirement stated?
The FDA Information Sheet Guidance for Sponsors, Clinical Investigators, and IRBs explains that the investigator must attach a CV or other statement of qualifications to Form FDA 1572 so the sponsor can assess the investigator’s qualifications. For IND studies, the underlying obligations sit in 21 CFR Part 312, and ICH E6 Good Clinical Practice expresses the same principle internationally.
When does Form FDA 1572 need to be updated?
Form FDA 1572 is required to be updated if the investigator is added to another protocol in the study. When the 1572 changes, the attached qualification statement should remain accurate and consistent with it.
If there is no two-year rule, why do so many sponsors ask for it?
A periodic CV refresh is a quality and risk-management convention rather than a regulatory mandate. People change roles, complete new training, and gain new experience, so a current CV is easier to defend during an inspection. Following the sponsor’s stated requirement is the safest course.
What happens if the CV is out of date during an inspection?
There is no automatic violation simply because a CV is old. The concern is whether the site can demonstrate that the investigator is currently qualified for the specific protocol. A stale or inconsistent CV can leave that evidence lacking and invite broader questions about whether essential documents are being kept current.
