Periodically, the U.S. Food and Drug Administration (FDA) publishes guidance to industry on various matters under its regulatory jurisdiction. Typically, the agency would publish a draft copy and request input from the American public during a specific period. Upon the expiration of the comments period, the agency publishes a final version of the guidance, which represents the agency’s current thinking on the subject-matter.
Although FDA guidance documents do not establish legally enforceable requirements, they nevertheless, influence industry. Consequently, it is important for industry to be attuned to FDA activity in this area, and to participate in the comment/review period preceding the final guidance.
THE DRAFT GUIDANCE
In August 2011, the FDA published a draft guidance intended to assist sponsors of clinical investigations in developing risk-based monitoring strategies and plans for investigational studies of medical products, including human drug and biological products, medical devices, and combinations thereof. Recognizing that sponsors have a variety of monitoring approaches, the guidance recommends greater use of centralized monitoring strategies.
According to the FDA, there is a growing consensus that risk-based approaches to monitoring, such as focusing on the most critical data elements, are more likely to ensure subject protection and overall study quality, and will permit sponsors to monitor the conduct of clinical investigations more effectively than routine visits to all clinical sites and 100% data verification.
The primary goal of the guidance is to enhance human subject protection and the quality of clinical trial data. This goal aligns with the objective of most sponsors of clinical investigations, which underscores the importance of industry input to the final guidance. Industry had 90 days to comment on the draft recommendations.
COVERAGE OF THE FINAL GUIDANCE
In February 2012, the FDA published the final version of the Guidance for IRBs, Clinical Investigators, and Sponsors: IRB Continuing Review after Clinical Investigation Approval. The document represents the agency’s current thinking on the topic. This document supersedes the 1988 Information Sheet, Continuing Review After Study Approval published by the FDA Office of Health Affairs.
As indicated in the introduction to the final document, the guidance is intended to assist institutional review boards (IRBs) in carrying out their continuing review responsibility under 21 CFR 56.108(a) and 56.109(f) by providing recommendations regarding the criteria, process, and frequency of continuing review. In addition, the guidance is intended to help clinical investigators and sponsors better understand their responsibilities related to continuing review.
What exactly does the guidance cover? The following highlights the contents of the final guidance.
1. Criteria for Approving Research During Continuing Review
The IRB makes its continuing review determination by considering whether any new information is available that would affect the IRB’s prior finding that the research meets the criteria in 21 CFR 56.111 (the relevant FDA regulation). Specifically, in order to approve research, the IRB must determine that all of following requirements are satisfied:
- Risks to subjects are minimized;
- Risks to subjects are reasonable in relation to anticipated benefits, if any, to subjects, and the importance of the knowledge that may be expected to result;
- Selection of subjects is equitable;
- Informed consent will be sought from each prospective subject or the subject’s legally authorized representative, and appropriately documented;
- Where appropriate, the research plan adequately provides for monitoring the data collected to ensure the safety of subjects;
- Where appropriate, there are adequate provisions to protect the privacy of subjects and to maintain the confidentiality of data;
- Appropriate additional safeguards are included to protect vulnerable subjects; and where the study involves children, the research complies with 21 CFR Part 50, Subpart D.
2. Process for Conducting Continuing Review
Continuing review takes place at a convened meeting of the IRB. Investigators are responsible for ensuring that studies they conduct comply with applicable regulatory requirements. FDA encourages IRBs to make investigators aware of the IRB’s procedures and recommends that the IRB’s written procedures call for submission of a detailed list of information for consideration by the IRB in continuing review.
The necessary information includes the following:
- A written progress report/brief project summary;
-
The latest version of the protocol and sample informed consent document(s) in use at the site;
-
Any proposed modifications to the informed consent document or protocol;
-
The current Investigator’s Brochure, if any, including any modifications;
-
Any other significant information related to subject risks, such as the most recent report, if any, from data monitoring committees (DMCs);
-
Aggregate information about relevant regulatory actions occurring since the last review that could affect safety and risk assessments.
3. Key Topics to Consider During Continuing Review
FDA recommends that when conducting continuing review and evaluating whether research continues to satisfy the criteria for IRB approval of research, IRBs should pay particular attention to the following areas:
- Risk Assessment;
- Adequacy of Informed Consent;
- Local Issues, and
- Trial Progress
4. When Expedited Review Procedures May Be Used for Continuing Review
This regulation permits continuing review to be conducted using expedited procedures if certain requirements are met. Where a study qualifies for expedited review, the review may be conducted by the IRB chairperson or one or more experienced reviewers designated by the chairperson from among the IRB members.
The current list of research eligible for expedited review identifies nine categories of research. Research that meets the requirements of categories (1) through (7) at the time of review may qualify for expedited review whether that is initial or continuing review. In general, research that qualified for expedited review under one of these seven categories at the time of initial review will continue to qualify for expedited continuing review. Categories (8 and 9) apply only to continuing review of research previously approved by the convened IRB.
5. Frequency of Continuing Review
FDA regulations require an IRB to conduct continuing review of research at intervals appropriate to the degree of risk posed to the subjects, but not less than once a year. However, more frequent reviews may be appropriate (i.e. conducted more than once per year), for example, in cases where study risks require close monitoring.
FDA recommends that the IRB should consider the following factors when deciding on an appropriate interval for continuing review:
- The nature of and any risks posed by the clinical investigation;
- The degree of uncertainty regarding the risks involved;
- The vulnerability of the subject population;
- The experience of the clinical investigator in conducting clinical research;
- The IRB’s previous experience with that investigator and/or sponsor (e.g., compliance history, previous problems with the investigator obtaining informed consent, prior complaints from subjects about the investigator);
- The projected rate of enrollment; and
- Whether the study involve novel therapies.
6. Determining the Effective Date of Initial IRB Approval and the Dates for Continuing Review
The guidance discusses likely scenarios regarding the logistics of determining the effective dates of the IRB initial approval, the expiration of the approval and continuing review. FDA recommends that the IRB’s written procedures should describe how the IRB determines the effective date of approval for the study and how the date and period of approval is communicated to the clinical investigator.
For example, FDA recognizes the logistical advantages of keeping the expiration date of the IRB approval period constant from year to year throughout the life of the research. The agency recommends that IRBs that adopt a procedure for maintaining fixed anniversary dates for the expiration of annual IRB approvals should include a description of this procedure in their written procedures.
7. Communicating the IRB’s Continuing Review Determination
Under the FDA regulations, the IRB must notify investigators and the institution in writing of its decision to approve or disapprove the proposed research activity or of modifications required to secure IRB approval of the research activity. If the IRB decides to disapprove a research activity, it should include the reasons for its decision and give the investigator an opportunity to respond in person or in writing.
FDA encourages sponsors, clinical investigators, and IRBs to communicate with one another to protect the rights and welfare of study subjects.
SUMMARY
While the above includes the gist of the guidance document, it is important that the IRBS, clinical investigators, sponsors and other interested parties do their due diligence and check out the full document available at the FDA website. As reflected in other articles on this blog, ignorance or failure to comply with the regulatory requirements result in unpleasant and probably costly consequences.
