Throughout the Total Product Life Cycle (TPLC) of a medical device the device may require changes. A primary indicator of if or what type of PMA submission is needed is the nature of the data, if any, that is needed to demonstrate the safety and effectiveness of the changes. Amendments (§ 814.37) or supplements (§814.39) are submitted to the Food and Drug Administration (FDA) for changes to the original Premarket Approval (PMA) submission.
A PMA supplement is the submission required for a change affecting the safety or effectiveness of the device for which the applicant has an approved PMA; additional information provided to FDA for PMA supplement under review are amendments to a supplement.
A PMA amendment includes all additional submissions to a PMA or PMA supplement before approval of the PMA or PMA supplement OR all additional correspondence after PMA or PMA supplement approval.
After FDA has approved a PMA, an applicant must submit a PMA supplement for review and approval by FDA before making any change affecting the safety or effectiveness of the device unless FDA has advised that an alternate type of submission is permitted for a particular change. All changes must meet the requirements of the Quality System regulation (current good manufacturing practices) under 21 CFR Part 820 including the design control requirements under §820.30. Changes for which an applicant must submit a PMA supplement include, but are not limited to, the following types of changes if they affect the safety or effectiveness of the device:
An applicant may make a change in a device after FDA's approval of the PMA without submitting a PMA supplement if: (1) the change does not affect the device's safety or effectiveness, and (2) the change is reported to FDA in a postapproval periodic report (annual report) required as a condition of approval of the device, e.g., an editorial change in labeling which does not affect the safety or effectiveness of the device. Trivial changes, such as changes in the color of a label, would not have to be included in the postapproval periodic report.
The methods of notification and FDA involvement of changes to a PMA approved medical device depend on the type of change made. A summary of the types of notification and FDA involvement is outlined below. For additional information regarding the type of PMA supplement that should be submitted, please refer to the guidance document Modifications to Devices Subject to Premarket Approval (PMA) - The PMA Supplement Decision-Making Process.
After FDA approves a PMA, any change described below that enhances the safety of the device or the safety in the use of the device [§814.39(d)(2)] may be placed into effect by the applicant prior to the receipt of a written FDA order approving the PMA supplement, but after the applicant receives specific acknowledgment that the application qualifies for review under §814.39(d)(2) provided:
The following changes are permitted [§814.39(d)(1)]:
The applicant is encouraged to contact the PMA Staff to assist in determining if the change meets the requirements of §814.39(b).
Additional guidance can be found in "30-Day Notices and 135-Day PMA Supplements for Manufacturing Method or Process Changes, Guidance for Industry and CDRH".
Note: 30-day Notice is not the same as a 30-day Supplement. See below for information regarding the 30-day Supplement.
PMA Manufacturing Site Change Supplement (§814.39(a)(3)
The information submitted to the FDA in the “site change supplement” must demonstrate compliance with the Quality System (QS) Regulation (§820). A preapproval inspection may be necessary to evaluate the firm’s implementation of the QS regulation requirements. The following factors are considered when determining whether to conduct a preapproval inspection for the “site change supplement”:
FDA will identify a change to a device for which the applicant has an approved PMA and for which a PMA supplement is not required under 814.39(a). FDA will identify such a change in an advisory opinion under §10.85, if the change applies to a generic type of device. Such changes will be identified in written correspondence to each PMA holder who may be affected by FDA's decision.
FDA will require that a change, for which a PMA supplement under §814.39(a) is not required, to be reported to FDA in a periodic (annual) report. In written correspondence, FDA will identify the type of information that is to be included in the report.
If FDA requires that the change be reported in a periodic report, the change may be made before it is reported to FDA.
For additional information regarding PMA annual reports please see the Guidance for Industry and Food and Drug Administion Staff: Annual Reports for Approved Premarket Approved Applications (PMA).
An applicant may amend a pending PMA or PMA supplement to revise existing information or provide additional information. FDA may request that the applicant amend their PMA or PMA supplement with any information about the device that is necessary to complete the review of the PMA or PMA supplement.
If the applicant submits a major PMA amendment on his or her own initiative the review period may be extended up to 180 days. A major amendment is one that contains significant new data from a previously unreported study, significant updated data from a previously reported study, detailed new analyses of previously submitted data, or significant required information previously omitted.
A PMA amendment must include the PMA or PMA supplement number assigned to the original submission and the reason for submitting the amendment.
Applicants may voluntarily withdraw their PMA or PMA supplement. If FDA requests an applicant to submit a PMA amendment, and a written response to FDA's request is not received within 180 days, FDA will consider the pending PMA supplement to be withdrawn voluntarily by the applicant (abandoned).
An applicant may resubmit a PMA or PMA supplement that was withdrawn, that FDA has refused to accept for filing, or that FDA has disapproved. A resubmitted PMA or PMA supplement must comply with the requirements of §814.20 or §814.39, respectively, and must include the PMA number assigned to the original submission as well as the applicant's reason for resubmission.
All procedures and actions that apply to a PMA application under §814.20 also apply to PMA supplements, except that the information required in a supplement is limited to that needed to support the change. A summary is required only if there are new indications for use of the device, significant changes in the performance or design specifications, circuits, components, ingredients, principles of operation, or physical layout of the device, or when otherwise required by FDA.
The applicant should submit a valid eCopy of their PMA Supplement. The eCopy should be sent to CDRH’s or CBER’s Document Control Center (DCC). The current mailing address for CDRH’s DCC and a link to CBER’s DCC’s mailing address are provided on the eCopy Program for Medical Device Submissions webpage.
Applicants should also clearly identify on the CDRH Premarket Review Submission Cover Sheet the type of PMA supplement.
To minimize delays in processing of PMA submissions, it is important that the applicant's cover letter correctly identify the type of submission, i.e., a PMA supplement, an amendment to a pending PMA or PMA supplement, or a required periodic report to an approved original PMA, PMA supplement or report amendment. Although FDA correspondence requesting additional information or approving a PMA submission identifies the form in which a subsequent submission is to be made, the incidence of incorrectly identified submissions has been significant. Delays in FDA processing occur when a document is misidentified and the submission must be reprocessed.
The general full format of the cover letter for a PMA supplement appears below. Only the subject section and opening sentence(s) are provided for the various types of PMA supplement submissions. In several instances, alternative opening statements are included to address specific situations.
