510k Electronic Submission Guidance for FDA 510k Submissions

This is an overview of the updated 510k electronic submission guidance document that the FDA released on October 2, 2023.

What’s included in the 510k electronic submission guidance?

As with any FDA guidance, there is an introduction and background regarding the reason for the updated guidance document (i.e., eSTAR guidance). At the very beginning of the document (i.e., page 3) the reference to the RTA Guidance was deleted, because there is no longer an RTA screening process with the implementation of the FDA eSTAR templates. The updated guidance explains on page 6 that “The CDRH Portal will automatically verify that the eSTAR is complete, and therefore we do not expect to receive incomplete 510(k) eSTARs.” In the scope section, the FDA specifies that this document is specific to 510k submissions using the eSTAR template. The document also explains that CBER conducted a pilot with the eSTAR template in June 2022 and now the FDA eSTAR template must be used in conjunction with the CDRH Portal for submission of a 510k to CBER. The FDA has plans to release a similar De Novo submission guidance for using the eSTAR template, but this has not happened in the year since the FDA announced the intention to do so. In the “Significant Terminology” section of the guidance (i.e., Section IV), the FDA provides definitions for each of the different types of submissions: eCopy, eSubmitter, etc. In the “Current Electronic Submission Template Structure, Format, and Use” section of the guidance (i.e., Section V), the FDA modified the term used for the company that is applying for 510k clearance from “Submitter” to “Applicant,” because sometimes a regulatory consultant or 3rd party reviewer is submitting the 510k on behalf of the applicant. On page 12 of the updated guidance, the FDA added “Withdrawal requests” to the list of 510k submissions/information that is exempt from the 510k electronic submission requirements. In the next to last section of the electronic submission guidance, the FDA provides a table outlining all of the sections of the new eSTAR template. The table is reproduced later in this article. If you are interested in a tutorial on completing each section outlined in the table, we recommend purchasing Medical Device Academy’s 510(k) Course. The last section of the eSTAR guidance indicates the timing for compliance with the updated guidance (i.e., October 1, 2023).

What is the deadline for compliance with the guidance?

The deadline has now passed. The new eSTAR template must be used for all 510k and De Novo submissions as of October 1, 2023. You must upload the new FDA eSTAR submissions using the CDRH Portal. You will need to request an account using a registration hyperlink.

What’s missing from this 510k submission guidance?

The updated 510k electronic submission guidance does not provide information regarding the receipt date for electronic submissions made through the new customer collaboration portal (CCP) created by CDRH. The image below is a screen capture of the current CCP upload webpage. It includes the following statement, “Send your submission before 16:00 ET on a business day for us to process it the same day.” This statement was added sometime in August or September, but the FDA has not released a detailed explanation. This statement makes it clear that the FDA is not promising to process a submission the “same day” if the submission is received after 4:00 p.m. ET. However, “processed” does not have the same meaning as “receipt date.”

Another element missing from this updated guidance is a reference to human factors documentation. For any devices that have a user interface that is different from the predicate device, and for software devices, the FDA requires documentation of your human factors process to make sure that differences in the user interface do not result in new or different risks when compared to the predicate device. The 2016 FDA guidance for human factors has not been updated, but FDA reviewers continue to issue deficiencies related to the objective evidence provided in a 510k for human factors validation.

The FDA must be consistent in the wording for “Hours for Receipt of Submission” because this affects submissions at the end of the fiscal year, but it also affects any submissions with a deadline for response to an RTA Hold, AI Response, and IDE submissions. The CDER and CBER divisions of the FDA address the need for defining the date of receipt in a guidance document specific to this topic, “Providing Regulatory Submissions in Electronic Format–Receipt Date.” Below is a screen capture copied from page 4 of the guidance.

What are the new sections for a 510k submission?

In 2019, the FDA released a guidance document on the “Format of Traditional and Abbreviated 510(k)s.” That guidance outlines the 20 sections of a traditional 510k submission that have been used for decades. However, the new 510k electronic submission guidance has no numbering for the sections of the eSTAR template, and there are 22 sections instead of 20 sections. Several of the new sections are elements of the current FDA submission cover sheet (i.e., FDA Form 3514), and some sections exist in the 2019 guidance that were eliminated, such as: “Class III Summary and Certification.” Therefore, Medical Device Academy is recreating 100% of our 510k training webinars to explain how our 510k templates are used with the 510k eSTAR template and how to fill in the PDF form. To prevent confusion between the two formats, we are using letters for each section in the eSTAR template instead of numbers (i.e., A-V instead of 1-20). Table 1 from the new eSTAR guidance is reproduced below for your information.

Important information in the eSTAR guidance

In Table 1 above, there are 14 hyperlinks to various FDA guidance documents. These links are extremely helpful when you have questions about a specific question. Unfortunately, the 510k electronic submission guidance document will quickly become out-of-date as guidance documents are updated and made obsolete. In particular, one of the A-list final guidance documents that was planned for FY 2023 was the FDA cybersecurity guidance. The updated cybersecurity guidance was finally released last week.
