Maintaining the IDE

The Pre-IDE Process

Review the FDA Guidance titled Significant Risk and Nonsignificant Risk Medical Device Studies.  The guidance document provides definitions and examples of Significant Risk (SR) and Nonsignificant Risk (NSR) studies. To find information on a specific device or type of device, search the database maintained by CDRH. 

The sponsor-investigator makes the initial risk determination for the proposed study and presents it to the IRB.  The IRB then reviews the sponsor-investigator’s risk determination and agrees or disagrees.  FDA is available to help the sponsor-investigator and the IRB in making the determination.  If needed, FDA is the final arbiter.

Sponsors of an SR study are encouraged to contact FDA to obtain further guidance prior to the submission of an IDE application. This will be especially beneficial to new sponsors who have not previously had contact with the agency and for sponsors proposing to study new technologies or new uses for existing technologies. The pre-IDE Program is primarily designed to benefit the IDE sponsor.  By allowing the sponsor to obtain early FDA input on selected (by the sponsor) sections of the IDE application, FDA hopes that the initiation of clinical trials will be facilitated.

This communication may take the form of telephone conference calls, videoconferences, or face-to-face discussions. The pre-IDE Program is intended as a way for sponsors to obtain preliminary comments on their pre-clinical data (bench/animal testing) or the investigational plan (clinical protocol) in a timely manner.  It will also allow FDA personnel to familiarize themselves with the new technologies. 

For more information, please refer to the guidance Requests for Feedback and Meetings for Medical Device Submissions: The Q-Submission Program. 

The sponsor-investigator should contact the Office of Product Evaluation and Quality (OPEQ) reviewing division directly or may contact the FDA CDRH IDE staff for assistance at 301-796-5640.

For comprehensive regulatory education about medical devices and radiation-emitting products, please see Device Advice and CDRH Learn. Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

For questions about devices regulated by the Center for Biologics Evaluation and Research (CBER), contact CBER’s Office of Communication, Outreach and Development (OCOD) at either 1-800-835-4709 or Industry.Biologics@fda.hhs.gov.

If you think a pre-IDE meeting with the FDA is warranted, please contact ResearchGo for assistance. Templates for a pre-submission meeting request and briefing package are provided below.

IDE Preparation

Develop the IDE Study Protocol

The IDE Protocol is the basis for both the IRB Application and the initial IDE submission:

• Review the IDE Protocol Template for required content.  A completed protocol and cover letter must be included in the IDE application.
• Start with a protocol synopsis (pages 8 to 10 of the protocol template).   The protocol synopsis will be valuable if you are planning a pre-IDE meeting.   
• Compile a reference list. Include all published articles and unpublished reports or manuscripts cited.  Collect a copy of each article or report listed.

Prepare the Initial IDE Submission

• The IDE Sponsor-Investigator compiles information in three broad areas:

1. Report of Prior Investigations - published and unpublished reports of all prior clinical, animal, and laboratory testing of the device
2. Investigational Plan - a complete written study protocol    
3. Manufacturing Information - a description of the methods, facilities, and controls used for the manufacture, processing, storage, and, where appropriate, installation of the device

• The IDE Sponsor-Investigator writes the IDE Application (including the Investigator's Certification of Financial Interest) and the IDE Cover Letter.

Please review the IDE Required Elements for additional information

IDE Submission

eCopy Program

On October 3, 2022, the FDA announced that you may now send electronic copy (eCopy) submissions online through the CDRH Customer Collaboration Portal ("CDRH Portal"). For more details, refer to eCopy Medical Device Submissions.

An electronic copy (eCopy) is a duplicate device submission in electronic format of the previously required paper copy submission sent to the FDA.  An electronic copy is not considered an electronic submission.

For details on the eCopy program, including the technical standards for eCopies, refer to the eCopy guidance: eCopy Program for Medical Device Submissions.

An eCopy is required for IDE submissions. For additional details, review Section III. "For what submission types is an eCopy required?" in the eCopy guidance.

FDA Response

FDA will reply to the submission with an acknowledgement letter containing:

• the date of receipt of the IDE application
• the IDE number assigned to your application
• the name of the project manager to address in future submissions under the IDE

An IDE application is considered approved 30 days after it has been received, unless FDA informs the sponsor-investigator otherwise. An IDE may be approved, approved with conditions, or disapproved. It is advised that you obtain written confirmation (e.g. email) that the FDA review has been completed and that the Study May Proceed. Please upload FDA Study May Proceed confirmation in webIRB/BruinIRB. In cases of disapproval, a sponsor has the opportunity to respond to the deficiencies and/or to request a regulatory hearing under 21 CFR Part 16.

Amendments, Safety Reports & Annual Reports (FDA Guidance)

IDE sponsor-investigators are required under 21 CFR 812.150 to submit the following reports:

Unanticipated adverse device effects (UADE)
A UADE is any serious adverse effect on health or safety, any life-threatening problem or death caused by, or associated with a device, if that effect, problem, or death was not previously identified in nature, severity, or degree of incidence in the application; or any other unanticipated serious problem associated with a device that relates to the rights, safety, or welfare of subjects.

A UADE Report consists of a completed Form FDA 3500A and an analysis of the event in a cover letter, submitted to FDA and all reviewing IRBs and investigators within 10 working days after the sponsor first receives notice of the adverse effect.  

Withdrawal of IRB approval
Submitted to FDA and all reviewing IRBs and participating investigators within 5 working days after receipt of notice of the withdrawal of IRB approval of an investigation (or any part of an investigation)

Withdrawal of FDA approval
Submitted to all reviewing IRBs and participating investigators within 5 working days after receipt of notice of any withdrawal of FDA approval

Current list of investigators with addresses
Submitted to FDA every six months

Progress reports
Submitted to FDA and all reviewing IRBs at regular intervals and at least yearly.  A suggested format for the Progress Report can be found on the CDRH website.

Recalls and device disposition
Submitted to FDA and all reviewing IRBs within 30 working days after receipt of a request to return, repair, or dispose of any unit of an investigational device. The report must state why the request was made.

A final report
For a significant risk device, the sponsor must submit a final report notifying FDA and all reviewing IRBs within 30 working days of the completion or termination of the investigation. The sponsor must also submit a final report to FDA and all reviewing IRBs and participating investigators within 6 months after the completion or termination of the investigation.  

Use of a device without informed consent
Submitted to FDA within 5 working days after receipt of notice of such use

SR device determination
Submitted to FDA within 5 working days after determination by an IRB that the device is a SR device and not an NSR device as the sponsor had proposed
