In accordance with the CFR, for at least how many years after the completion of a study must the clinical investigator provide the sponsor with…

According to the U.S. Code of Federal Regulations (CFR), the sponsor is required to obtain a commitment from the clinical investigator to promptly update their financial disclosure information. This obligation extends throughout the duration of the clinical investigation and continues for one year following the completion of the study. This requirement ensures that the regulatory agency (FDA) can assess any potential conflicts of interest that may arise or become known shortly after the study's conclusion, which could potentially influence the interpretation or reporting of the study results.

B. Two years: This is incorrect. The regulation explicitly specifies a one-year period for updating financial information post-study completion, not two. Two years is often associated with record retention requirements.

C. Three years: This is incorrect. The mandated period for updating financial information is one year.

D. Five years: This is incorrect. The regulation clearly defines the post-study update period as one year.

1. U.S. Code of Federal Regulations, Title 21, Part 54.4(b). "For any clinical investigator who is not an employee of the sponsor or of a contract research organization, the sponsor shall obtain a commitment from the clinical investigator to promptly update the information required by this section if any relevant changes occur during the course of the investigation and for 1 year following completion of the study."

2. U.S. Food and Drug Administration. (2013, February). Guidance for Clinical Investigators, Sponsors, and IRBs: Financial Disclosure by Clinical Investigators. Page 10, Section IV.C. "The sponsor must also obtain a commitment from the clinical investigator to update this information promptly if any relevant changes occur during the course of the investigation and for 1 year following completion of the study (21 CFR 54.4(b))."

3. University of Pittsburgh, Human Research Protection Office. (2023). Investigator Manual. Chapter 16: Financial Conflict of Interest. This manual, typical of university research compliance programs, reiterates the federal requirement: "Investigators must agree to update their financial disclosure information if any relevant changes occur during the study and for one year following study completion."
