Introduction FDA plays a critical role in protecting the United States (U.S.) from threats such as emerging infectious diseases, including Coronavirus Disease 2019 (COVID-19). FDA is committed to providing timely guidance to support response efforts to the COVID-19 pandemic. FDA recognizes that it will take time for device manufacturers, device distributors, healthcare facilities, healthcare providers, patients, consumers, and FDA to adjust from policies adopted and operations implemented during the COVID-19 pandemic to “normal operations.” To provide a clear policy for all stakeholders and FDA staff, the Agency is issuing this guidance to describe FDA’s general recommendations for this transition process with respect to devices issued emergency use authorizations (EUAs) related to COVID-19, including recommendations regarding submitting a marketing submission, as applicable, and taking other actions with respect to these devices. FDA is concurrently issuing a companion transition guidance to describe FDA’s recommendations for devices that fall within certain enforcement policies issued during the COVID-19 public health emergency (PHE). FDA believes these transition guidances will help prepare manufacturers and other stakeholders for the transition to normal operations and foster compliance with applicable requirements under the FD&C Act and its implementing regulations. In general, FDA’s guidance documents do not establish legally enforceable responsibilities. Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word *should* in Agency guidances means that something is suggested or recommended, but not required. ## II. Background In 2019, an outbreak of respiratory disease caused by a novel coronavirus began. The virus has been named “SARS-CoV-2,” and the disease it causes has been named “Coronavirus Disease 2019” (COVID-19). On January 31, 2020, the Secretary of Health and Human Services (HHS) issued a declaration of a PHE related to COVID-19 in accordance with section 319 of the Public Health Service Act (PHS Act) and mobilized the Operating Divisions of HHS. In addition, on March 13, 2020, the President declared a national emergency in response to COVID-19. On February 9, 2023, the HHS Secretary renewed the section 319 PHE declaration related to COVID-19, effective February 11, 2023. The section 319 PHE declaration related to COVID-19 is anticipated to expire at the end of the day on May 11, 2023. FDA has authorized the emergency use of devices under section 564 of the Federal Food, Drug, and Cosmetic Act (FD&C Act). Section 564 of the FD&C Act authorizes FDA, after the HHS Secretary has made a declaration of emergency or threat justifying authorization of emergency use (an “EUA declaration”), to authorize the emergency use of an unapproved product or an unapproved use of an approved product for certain emergency circumstances. FDA may issue an EUA to allow a product to be used to diagnose, treat, or prevent a serious or life-threatening disease or condition referenced in the EUA declaration, when the statutory criteria are met, including FDA’s determination that, based on the totality of scientific evidence, the product may be effective for such use, the known and potential benefits outweigh the known and potential risks for such use, and that there are no adequate, approved, and available alternatives. An EUA issued under section 564 of the FD&C Act remains in effect for the duration of the relevant EUA declaration, unless FDA chooses to revoke the EUA because the criteria for issuance are no longer met or revocation is appropriate to protect public health or safety. An EUA declaration under section 564 of the FD&C Act is distinct from, and is not dependent on, a declaration by the HHS Secretary of a PHE under section 319 of the PHS Act. The device EUAs related to COVID-19 remain in effect until the relevant EUA declaration under section 564 of the FD&C Act is terminated or FDA otherwise revokes a specific EUA, [^14] even if the section 319 PHE declaration related to COVID-19 expires before then. [^15] Given the magnitude of the response to the COVID-19 pandemic, including the number of devices issued EUAs, FDA recognizes that stakeholders may need time to adjust after the termination of the device EUA declarations to help ensure an orderly and transparent transition to normal operations. Further, FDA is taking into account that the manufacture, distribution, and use of devices in the context of the COVID-19 pandemic raises unique considerations. These unique considerations include, for example, the manufacturing of devices by non-traditional manufacturers to address supply issues and the distribution and use of capital or reusable equipment (e.g., ventilators, extracorporeal membrane oxygenation systems) under EUAs. FDA developed this guidance to describe a transition plan, among other things, to help avoid disruption in device supply and help facilitate compliance with applicable FD&C Act requirements after the termination of the relevant EUA declaration related to COVID-19 under section 564(b) of the FD&C Act. Section 564 of the FD&C Act provides a statutory framework describing the circumstances in which an EUA declaration shall terminate and the process for such termination. [^16] Under section 564(b) of the FD&C Act, the HHS Secretary is required to provide advance notice that an EUA declaration will be terminated and to publish such notice in the Federal Register. [^17] When an EUA declaration is terminated, all EUAs issued under that declaration also terminate. After an EUA declaration terminates, it ceases to be in effect and the emergency use of all products under the EUA declaration are no longer authorized. Pursuant to section 564(b)(2)(B) of the FD&C Act, when an EUA for an unapproved product ceases to be effective as a result of the termination of an EUA declaration, FDA must consult with the manufacturer of such product with respect to the appropriate disposition of the product. FDA believes that by issuing this guidance in draft with a proposed transition policy and requesting public comment (including from manufacturers of EUA-authorized devices), the Agency has satisfied the requirement to consult with manufacturers, while also efficiently managing Agency resources. To address any unique considerations or other issues related to disposition of product that are not otherwise discussed in this guidance, FDA recommends engagement with the Agency as soon as possible. [^18] HHS intends to publish the advance notice of termination of each EUA declaration [^19] pertaining to devices in the Federal Register 180 days before the day on which the EUA declaration is terminated. The advance notice of termination of each device EUA declaration may occur simultaneously or at different times, depending on whether the circumstances underlying such declarations continue to exist. [^20] For purposes of this guidance, FDA refers to the date on which an EUA is terminated as the “EUA termination date.” During the time between the advance notice of termination of an EUA declaration and the EUA termination date, manufacturers of devices with EUAs issued pursuant to such an EUA declaration and others [^21] must continue to comply with the terms of the devices’ respective EUAs, including applicable conditions of authorization [^22] identified in the EUA letters of authorization for the devices. FDA recommends that manufacturers of devices authorized under EUAs plan their post-EUA regulatory and disposition strategies now. When an EUA declaration is terminated, the Agency intends to promptly publish notice of termination of the associated EUAs in the Federal Register and an explanation of the reasons for the termination. [^23] ## III. Scope This guidance applies to devices that have been issued an EUA under section 564 of the FD&C Act on the basis of a device EUA declaration related to COVID-19. [^24] Current good manufacturing practice deviations authorized under section 564A(c) of the FD&C Act are outside the scope of this guidance. This guidance does not apply to devices for which FDA has revoked the EUA under section 564(g)(2)(B)-(C) of the FD&C Act because the criteria under section 564(c) of the FD&C Act were no longer met or because other circumstances made such revocation appropriate to protect the public health or safety. ## IV. Guiding Principles In developing this guidance, and its companion transition guidance regarding devices that fall within certain enforcement policies issued during the COVID-19 PHE, several guiding principles were followed. Some derive from existing policies and are widely known, and others are key to understanding the approach set forth in this guidance. Thus, anyone using this guidance should bear in mind the following guiding principles: - This guidance is intended to help facilitate continued patient, consumer, and healthcare provider access to devices needed in the prevention, treatment, and diagnosis of COVID-19. - FDA believes the policies and recommendations in this guidance will help to ensure an orderly and transparent transition for devices that fall within the scope of this guidance. FDA’s policies and recommendations in this guidance are consistent with the Agency’s statutory mission to both protect and promote the public health. [^25] - FDA’s policies and recommendations follow, among other things, a risk-based approach with consideration of differences in the intended use and regulatory history of devices, including whether the device is life-supporting or life-sustaining, [^26] capital or reusable [^27] equipment, a single-use device, [^28] and whether another version of the device is FDA-cleared or -approved. - As always, FDA will make case-by-case decisions regarding the enforcement of legal requirements in response to particular circumstances and questions that arise regarding a specific device or device type. This may include FDA revising or revoking an EUA, [^29] requesting a firm initiate a recall (see 21 CFR 7.45), [^30] or taking other actions, including an enforcement action. Moreover, FDA may revise the enforcement policies and recommendations in the guidance, as appropriate. ## V. Transition Plan for Devices Authorized Under an EUA As previously stated, FDA recognizes that it will take time for device manufacturers, device distributors, healthcare facilities, healthcare providers, patients, consumers, and the Agency to adjust from policies adopted and operations implemented during the COVID-19 pandemic to normal operations. FDA seeks to encourage and facilitate an appropriate transition period to help, among other things, avoid exacerbating product shortages and supply chain disruptions. This transition plan takes into account the advance notice(s) of termination of the EUA declarations pertaining to devices, and the discussion below contains recommendations regarding the preparation and submission of marketing submissions (including the timing of such submissions), manufacturers' actions if they do not wish to continue distributing their product after the EUA termination date, and the distribution of devices within the scope of this guidance. For purposes of this guidance, devices are considered to be "already distributed" if they are finished devices that are labeled and are in distribution in the U.S. supply chain or are in the possession of the end user. For purposes of this guidance, FDA would generally consider devices to be "in distribution" to mean those finished, labeled devices that are no longer in the manufacturer's possession that are in transit to or held in a third party’s device inventory not on behalf of the manufacturer, in a federal, state, or other governmental stockpile, or at a location where devices are then offered for direct sale to the end user. During the time between the advance notice of termination of an EUA declaration and the EUA termination date, manufacturers of devices with EUAs issued pursuant to such an EUA declaration and others must continue to comply with the terms of the devices’ respective EUAs, including applicable conditions of authorization identified in the EUA letters of authorization for the devices. FDA understands that there may be scenarios that are not specifically addressed in this guidance, but generally believes that the policies and recommendations described, regardless of the specific scenario for a manufacturer, will help avoid disruptions in critical devices and allow FDA to best manage its resources for review of marketing submissions. To address any unique considerations or other issues not otherwise discussed in this guidance, manufacturers may wish to initiate discussions with the Agency through the Q-Submission Program, including requesting feedback in Pre-Submissions. Manufacturers should submit any Pre-Submissions with the understanding that their device will no longer be authorized for emergency use beginning on the EUA termination date. If the manufacturer’s intent is to continue to distribute its device after the EUA declaration for the device has been terminated, the manufacturer should promptly start preparing, and FDA intends to help facilitate acceptance of, a marketing submission before the EUA termination date. For details on the Q-Submission Program, refer to the guidance “[Requests for Feedback and Meetings for Medical Device Submissions: The Q-Submission Program](https://www.google.com/url?q=https://www.fda.gov/regulatory-information/search-fda-guidance-documents/requests-feedback-and-meetings-medical-device-submissions-q-submission-program&sa=D&source=apps-viewer-frontend&ust=1734725789006654&usg=AOvVaw23XJU5bUWWiOVI7qzWrNcE&hl=en).” ### A. “Notifications of Intent” for Certain Reusable Life-Supporting or Life-Sustaining Devices Given the public health significance of certain reusable life-supporting or life-sustaining devices that have been issued an EUA, FDA requests that manufacturers of such devices submit to FDA information regarding whether or not they intend to submit a marketing submission to FDA and continue distributing their product after the EUA termination date. This information will assist the Agency in resource planning for marketing submission review and providing support to manufacturers. This request applies to EUA-authorized devices with a product code listed in Table 1: | Product Code | Device Type | Classification Regulation | |--------------|---------------------------------------------------------|---------------------------| | BSZ | Gas-machine, anesthesia | 21 CFR 868.5160 | | CAW | Generator, oxygen, portable | 21 CFR 868.5440 | | BTT | Humidifier, respiratory gas, (direct patient interface) | 21 CFR 868.5450 | | QAV | High flow/high velocity humidified oxygen delivery device | 21 CFR 868.5454 | | CBK | Ventilator, continuous, facility use | 21 CFR 868.5895 | | MNT | Ventilator, continuous, minimal ventilatory support, facility use | 21 CFR 868.5895 | | NOU | Continuous, ventilator, home use | 21 CFR 868.5895 | | MNS | Ventilator, continuous, non-life-supporting | 21 CFR 868.5895 | | ONZ | Mechanical ventilator | 21 CFR 868.5895 | | BTL | Ventilator, emergency, powered (resuscitator) | 21 CFR 868.5925 | | QOO | Ventilator tubing and accessories | No corresponding CFR section | || Manufacturers of the devices identified in Table 1 should submit the following information to the CDRH Document Control Center as soon as possible after issuance of this guidance: - General information about the manufacturer, including contact information, name and place of business, and email address; - EUA request number; - Submission number(s) for related premarket submissions; - A list of all model numbers or other device identifying information; - Whether the manufacturer plans to submit a marketing submission; and - If not planning to submit a marketing submission, the manufacturer should discuss, as applicable, its plans to discontinue distribution of the device, to restore the device to an FDA-cleared or -approved version, to provide a physical copy and/or electronic copy of updated labeling, and any other efforts to address or mitigate potential risks of devices already distributed as of the EUA termination date. The manufacturer should submit this information designated with the EUA request number as an “EUA report.” FDA recommends that manufacturers notate the following on the cover letter of the submission: “Attention: Notification of Intent.” To the extent the Notification of Intent contains trade secret information or confidential commercial or financial information, FDA will handle that information in accordance with applicable laws, including 21 CFR 20.61. ### B. Devices distributed after the EUA termination date For manufacturers of devices authorized under an EUA seeking the required marketing authorization for their devices, please refer to the recommendations and policies in the subsections below. FDA recommends that these manufacturers submit their marketing submissions to FDA with sufficient time for the submission to be accepted by FDA before the EUA termination date. The marketing submission should be administratively complete in that it includes all of the information necessary for FDA to conduct a substantive review. FDA understands there may be extenuating circumstances that may make doing so difficult (e.g., ongoing clinical trial or longer term non-clinical studies). Manufacturers in such circumstances should engage with the Agency early in the transition period. FDA is taking into account that the use of devices during the COVID-19 pandemic may allow manufacturers to utilize a variety of data sources in their marketing submission. As such, FDA anticipates many manufacturers may wish to reference data from related marketing authorizations and submissions, and use real-world data obtained as a result of device use during the COVID-19 pandemic. FDA recommends that marketing submissions include in the cover letter a statement that the device is/was previously authorized under an EUA and the EUA request number, as well as submission number(s) for related premarket submissions. This information will help FDA track devices that are transitioning from an EUA to the required marketing authorization, facilitate review of the submission, and help ensure that transitioning devices can be appropriately considered in light of the policy described in Section V.B.(2) of this guidance. #### (1) Recommendations for “Transition Implementation Plan” FDA anticipates that some marketing submissions will include changes or updates to the device and/or its labeling compared to the product that has been distributed under the EUA. For example, a manufacturer may have distributed a singleplex in vitro diagnostic assay under an EUA, and the manufacturer intends to submit a marketing submission for a multiplex in vitro diagnostic assay; or a manufacturer may have distributed a remote monitoring device under an EUA, and the manufacturer intends to submit a marketing submission for such remote monitoring device with an additional, new indication. In addition, in some cases, a manufacturer may not receive a positive decision from FDA on its marketing submission. To help address all of these situations efficiently, FDA recommends that manufacturers include in the cover letter of their marketing submission a “Transition Implementation Plan” that addresses the manufacturers’ plans for dealing with devices already distributed in the case of a positive decision as well as in the case of a negative decision on the marketing submission. To the extent the Transition Implementation Plan contains trade secret information or confidential commercial or financial information, FDA will handle that information in accordance with applicable laws, including 21 CFR 20.61. FDA recommends that the Transition Implementation Plan include the following information, as applicable: - Estimated number of devices under an EUA that are currently in U.S. distribution; - An explanation of the manufacturer’s benefit-risk based plan for disposition of already distributed product in the event of a negative decision on the marketing submission. If the manufacturer is proposing to leave already distributed product in place, the plan should address the rationale for doing so and considerations such as the following, where relevant: - Process for notifying patients, consumers, healthcare facilities, healthcare providers, and device distributors of the device’s regulatory status; - Process and timeline for restoring already distributed devices to an FDA-cleared or -approved version; - Process and timeline for providing a physical and/or electronic copy of updated labeling that accurately describes the product features and regulatory status (e.g., that the product lacks FDA clearance, approval, or authorization) for reusable devices. To help ensure accessibility to updated labeling for reusable life-supporting/life-sustaining devices, FDA recommends that stakeholders be provided an opportunity to request a physical copy of updated labeling, and after such request, be provided the requested labeling without additional cost; and - A description of the maintenance plan for already distributed devices. - An explanation of the manufacturer’s plans for addressing already distributed product in the event of a positive decision on the marketing submission, including considerations such as the following, where relevant: - Process for notifying patients, consumers, healthcare facilities, healthcare providers, and device distributors of the device’s regulatory status; and - Process and timeline for providing to users of already distributed devices updated labeling or components for the cleared or approved device, including updated labeling or components to reflect any cleared/approved changes to the already distributed device. FDA encourages manufacturers to collaborate with device distributors, healthcare facilities, healthcare providers, patients, and consumers, as appropriate, regarding their Transition Implementation Plan to assist all stakeholders with transition planning. Depending on FDA’s evaluation of the marketing submission, FDA may engage with the manufacturer during the Agency’s review of the submission to discuss the appropriate disposition of already distributed devices described in the Transition Implementation Plan. For marketing submissions that include changes to the device compared to the product that has been distributed under the EUA (e.g., modifications to address a cybersecurity concern), the manufacturer should discuss possible correction or removal with FDA regarding devices already distributed to the end user, as needed. As always, FDA will make case-by-case decisions regarding the enforcement of legal requirements in response to particular circumstances and questions that arise regarding a specific device or device type (e.g., requesting a firm initiate a recall (see 21 CFR 7.45) or taking other actions, including an enforcement action). #### (2) Enforcement policy for devices with a marketing submission under review by FDA As previously stated, FDA recognizes that it may take time for device manufacturers, including non-traditional device manufacturers, to adapt and adjust from their operations during the COVID-19 pandemic to normal operations. As such, at this time, FDA does not intend to object to the continued distribution of devices within the scope of this guidance after the EUA termination date where: - The manufacturer has submitted a marketing submission to FDA and it is accepted by FDA before the EUA termination date; and - FDA has not taken a final action on the marketing submission. For these same devices, while the device is under FDA review, FDA does not intend to object to the devices not bearing a Unique Device Identification (UDI) (see 21 CFR Part 801 Subpart B and Part 830) or complying with other applicable labeling requirements (see 21 CFR Part 801) where the device continues to be labeled as previously authorized under the EUA. As always, FDA will make case-by-case decisions regarding the enforcement of legal requirements in response to particular circumstances and questions that arise regarding a specific device or device type. The enforcement policy in this section (Section V.B.(2)) relates to FDA marketing authorization (e.g., 510(k) clearance), UDI, and certain labeling requirements. It does not apply to other legal requirements (such as registration and listing, Quality System (QS), and reports of corrections and removals requirements under 21 CFR Parts 807, 820, and 806, respectively) that may apply after the EUA termination date. Moreover, it does not apply after FDA has taken a final action on the marketing submission for a device. At that time, FDA expects manufacturers to comply with all applicable regulatory requirements for the device/manufacturer. Following the device’s marketing authorization, this includes labeling updates (see 21 CFR Part 801), compliance with UDI requirements (see 21 CFR Part 801 Subpart B and Part 830), and any applicable updates to registration and listing information, including the submission number (see 21 CFR Part 807 Subparts B-D). After marketing authorization, manufacturers also should follow the steps outlined in their Transition Implementation Plan. In addition, and as always, FDA will make case-by-case decisions regarding the enforcement of legal requirements in response to particular circumstances and questions that arise regarding a specific device or device type. This may include FDA revising or revoking an EUA, requesting a firm initiate a recall (see 21 CFR 7.45), or taking other actions, including an enforcement action. Moreover, FDA may revise the enforcement policies and recommendations in the guidance, as appropriate. As mentioned previously, FDA recommends that marketing submissions include in the cover letter a statement that the device is/was previously authorized under an EUA and the EUA request number, as well as submission number(s) for related premarket submissions. This information will help FDA track devices that are transitioning from an EUA to the required marketing authorization, facilitate review of the submission, and help ensure that transitioning devices can be appropriately considered in light of the policy described in this section (Section V.B.(2) of this guidance). In addition, during this transition period and after the EUA termination date, FDA may receive questions from stakeholders (e.g., other Agencies, governmental stockpilers, healthcare providers) about a device’s regulatory status for devices distributed as described in this section (Section V.B.(2)) while the marketing submission is under review by FDA. Typically, if a device has an EUA or conventional marketing authorization (e.g., 510(k) clearance), this information would be publicly available. The existence of a marketing submission under review is not typically disclosed unless certain circumstances apply, such as when the device is on the market. As such, for devices distributed as described in this section, FDA may share that a manufacturer is distributing such device as described in the policy in this guidance, which could indirectly reveal that the manufacturer has a marketing submission under review by FDA. #### (3) Additional considerations for EUA-authorized in vitro diagnostics – Clinical Laboratory Improvement Amendments of 1988 (CLIA) categorization and waivers In vitro diagnostics (IVDs) authorized under an EUA are generally authorized for use in specific settings, such as those certified as laboratories under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), that meet the requirements to perform high or moderate complexity tests, or for use at the point-of-care (POC), i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation. FDA’s determination that an EUA-authorized IVD is deemed to be in a particular category of examinations and procedures under CLIA is effective only while the relevant declaration under section 564(b) of the FD&C Act is in effect. Outside of EUAs, CLIA categorization typically is determined by FDA after FDA has cleared or approved a marketing submission. Prior to a CLIA categorization as moderate complexity or waived, an IVD is considered to be high complexity and, under CLIA, use of that test is limited to laboratories that are certified under CLIA, and that meet the requirements to perform tests of high complexity. For IVDs authorized under an EUA for use in laboratories certified under CLIA that meet the requirements to perform moderate complexity tests, FDA intends to categorize the test’s complexity immediately following FDA’s final action on the marketing submission, per FDA’s typical categorization process. For IVDs authorized under an EUA for use in patient care settings operating under a CLIA Certificate of Waiver, FDA intends to accept marketing submissions under the Dual 510(k) and CLIA Waiver by Application pathway, or Dual De Novo and CLIA Waiver marketing submissions modeled after the 510(k) and CLIA Waiver by Application pathway, as appropriate. Manufacturers intending to submit a Dual Submission are encouraged to consider the recommendations in the guidance “Recommendations for Dual 510(k) and CLIA Waiver by Application Studies,” for information on the process and content of Dual Submissions. Consistent with the recommendations in that guidance, data regarding actual use of the IVDs in CLIA-waived settings for comparison and reproducibility studies will be helpful in making a CLIA waiver determination. FDA anticipates that, in many cases, manufacturers will be able to reference data from related marketing authorizations and submissions, including the EUA request, and real-world data obtained as a result of use of the IVD under the EUA may be submitted in support of a CLIA Waiver by Application. As described in the guidance “Recommendations for Dual 510(k) and CLIA Waiver by Application Studies,” FDA recommends submitting a Pre-Submission to discuss planned study designs for comparison and reproducibility studies that support the marketing submission and the CLIA waiver, and the Dual Submission should be submitted following a Pre-Submission. For IVDs authorized under an EUA for home use, if a marketing submission for such test is subsequently cleared, approved, or authorized for home use, the test will be waived by regulation under 42 CFR 493.15(c), meaning that the test will be categorized as waived without the need for a CLIA Waiver by Application. FDA recommends that any marketing submission that may necessitate a CLIA categorization decision (e.g., tests intended for use in moderate complexity laboratories or in CLIA Certificate of Waiver settings) be submitted as soon as possible to facilitate FDA’s review of the marketing submission and CLIA categorization request (or CLIA Waiver by Application) prior to the termination of the EUA declaration to reduce the potential for disruption in distribution and use. For IVDs authorized under an EUA for use in high complexity, moderate complexity, and waived settings where, as described in Section V.B.(2) of this guidance, the manufacturer has submitted a marketing submission to FDA and it is accepted by FDA before the EUA termination date, and FDA has not taken a final action on the marketing submission or made a determination on CLIA categorization, at this time, FDA does not intend to object to the continued distribution and use of such tests consistent with the policy described in Section V.B.(2) of this guidance and in a manner consistent with the EUA that was in effect prior to the EUA termination date. ### C. Devices not distributed after the EUA termination date When a manufacturer does not intend to continue to distribute its device beyond the EUA termination date, at this time, FDA does not intend to object to the disposition and use[^67] of already distributed devices (i.e., FDA does not intend to request market removal[^68]) as follows: 1. Single-use, non-life-supporting/non-life-sustaining devices (e.g., face masks), including IVDs, that were distributed before the EUA termination date are used by the end user prior to the product expiration date,[^69] as applicable. 2. Reusable, non-life-supporting/non-life-sustaining devices (e.g., non-invasive remote patient monitoring devices) that were distributed before the EUA termination date are used by their end user and either: a. Are restored[^70] by the manufacturer to an FDA-cleared or -approved version of the device,[^71] or b. Have[^72] a physical and/or electronic copy of updated labeling that accurately describes the product features and regulatory status (e.g., that the product lacks FDA clearance, approval, or authorization). 3. Reusable life-supporting/life-sustaining devices (e.g., ventilators, extracorporeal membrane oxygenation systems, continuous renal replacement therapy systems) that were distributed before the EUA termination date are restored[^73] by the manufacturer to an FDA-cleared or -approved version of the device[^74] so that they may be used by their end user. If not restored, a physical and/or electronic copy of updated labeling that accurately describes the product features and regulatory status (e.g., that the product lacks FDA clearance, approval, or authorization) should be provided,[^75] and such devices are not to be used.[^76][^77] To help ensure accessibility to updated labeling, FDA recommends that stakeholders be provided an opportunity to request a physical copy of updated labeling, and after such request, be provided the requested labeling without additional cost. Manufacturers that do not intend to distribute their devices after the EUA termination date should also refer to relevant information included in this guidance in other sections (though note that recommendations in Section V.B. are intended only for manufacturers that intend to distribute their device after the EUA termination date). In addition, manufacturers should be aware of any applicable legal requirements for their device, such as adverse event reporting under 21 CFR Part 803, and are expected to comply with such requirements for the duration in which they are applicable, which may extend beyond the cessation of distribution. For IVDs authorized under an EUA for use in high complexity, moderate complexity, and waived settings that were already distributed before the EUA termination date, at this time, FDA does not intend to object to the continued use of such tests prior to the product expiration date in a manner consistent with the EUA that was in effect prior to the EUA termination date.[^78] Manufacturers may also voluntarily withdraw their devices from the market. For manufacturers that do not intend to continue distributing their devices and that intend to voluntarily withdraw their devices from the market, FDA recommends completing withdrawal of the devices from the market prior to the EUA termination date; otherwise, if withdrawal of the devices from the market is not completed prior to the EUA termination date, FDA recommends restoring and/or updating labeling for reusable non-life-supporting/non-life-sustaining devices and for reusable life-supporting/life-sustaining devices as outlined in the policy above prior to the EUA termination date. Manufacturers should be aware of any applicable legal requirements for their device, such as adverse event reporting under 21 CFR Part 803, and continue to comply with such requirements for the duration in which they are applicable, which may extend beyond the cessation of distribution or withdrawal. Generally, it is anticipated that, over time, legal requirements will no longer apply when the manufacturer’s device withdrawal activities are completed. FDA encourages manufacturers that do not intend to continue to distribute their devices after the EUA termination date to communicate with device distributors, healthcare facilities, healthcare providers, patients, and consumers, as appropriate, regarding their product disposition to assist all stakeholders with transition planning. In addition, thinking through elements of the “Transition Implementation Plan” outlined in Section V.B.(1) of this guidance may help manufacturers and stakeholders with this process. ### D. Discontinuing distribution of a device FDA expects manufacturers to discontinue distribution of a device within the scope of this guidance: 1. On the EUA termination date, if the manufacturer has not submitted a required marketing submission[^79] for its device and had it accepted by FDA before the EUA termination date; or 2. On the date the manufacturer receives a negative decision on its marketing submission as FDA’s final action, or on the date the manufacturer withdraws its submission or fails to provide a complete response to an FDA request for additional information[^80] within the allotted time identified in FDA’s letter. In addition, manufacturers should be aware of any applicable legal requirements for their device, such as adverse event reporting under 21 CFR Part 803, and continue to comply with such requirements for the duration in which they are applicable, which may extend beyond the cessation of distribution. Generally, to help determine the applicable legal requirements after cessation of distribution, FDA expects manufacturers of devices and others[^81] to review terms of the devices’ respective EUAs, including the conditions of authorization[^82] that were included in the EUA letters of authorization for the devices. FDA encourages manufacturers to communicate with device distributors, healthcare facilities, healthcare providers, patients, and consumers, as appropriate, regarding their product disposition to assist all stakeholders with transition planning. ### E. Quality System considerations FDA recognizes that there may be situations that raise unique compliance considerations, particularly regarding QS requirements. For example, non-traditional device manufacturers that previously operated under different quality standards or requirements may face challenges that take more time to address in transitioning to a system that fully complies with 21 CFR Part 820. FDA intends to take such considerations into account when making case-by-case compliance and enforcement decisions. Some manufacturers who intend to continue distributing their devices after the EUA termination date may choose to request an exemption or variance from a device QS requirement as outlined in 21 CFR 820.1(e) and section 520(f)(2) of the FD&C Act. Any such exemption or variance should be requested within 90 days of publication of the advance notice of termination of the EUA declaration pertaining to the device at issue to help ensure FDA considers your request in time. ### F. Laboratory developed tests (LDTs) For laboratory developed tests (LDTs)[^83] in general, FDA has generally exercised enforcement discretion, meaning that FDA generally does not exercise its authority to enforce the regulatory requirements for these devices, although it maintains that authority. FDA has not applied this general enforcement discretion approach to, among other LDTs, those used for declared emergencies under section 564 of the FD&C Act. As such, following termination of the EUA declaration for COVID-19 IVDs, FDA intends to have the same enforcement approach for COVID-19 LDTs as it does for other LDTs. ## VI. Examples The following hypotheticals are intended to illustrate the transition policy outlined above. To exemplify the timeline of the Transition Implementation Plan outlined in this section (Section VI. of this guidance), for purposes of the examples, FDA set the hypothetical advance notice of termination date for the EUA declaration pertaining to the device at issue as July 1 in Year 1, and the EUA termination date as January 1 in Year 2. This date is not intended to propose an actual advance notice of termination or EUA termination date; it is hypothetical and for illustrative purposes only. Note that these generalized examples do not account for every possible detail, risk, or consideration a manufacturer should evaluate or that may be relevant to FDA decisions regarding a particular device. ### Example 1 A single-use surgical mask that is intended for use in healthcare settings by healthcare personnel as personal protective equipment to provide a physical barrier to fluids and particulate materials was authorized for emergency use under an umbrella EUA for surgical masks. The manufacturer does not intend to continue distributing the surgical mask after the EUA is no longer in effect. On July 1, the advance notice of termination of the relevant EUA declaration is published. After July 1, the manufacturer continues to distribute the surgical masks and continues to comply with all conditions of authorization. On the EUA termination date (January 1), the relevant EUA declaration is terminated and the umbrella EUA is no longer in effect. On January 1, the manufacturer ceases distribution of the surgical mask. Before January 1, the manufacturer had recently sold surgical masks directly to retailers and device distributors. Some of the surgical masks are in transit to these customers, and others are being held in device distributors’ warehouses in the U.S. The policies included in this guidance relate to the following actions by the device manufacturer and others: - The surgical masks in transit or in device distributors’ warehouses remain distributed (they were already distributed by the EUA termination date), and they are used by the end user prior to their expiration date. - If on January 1, some of the surgical masks are in the manufacturer’s possession, the surgical masks in the manufacturer’s possession are not subsequently distributed (they were not already distributed by the EUA termination date). - The manufacturer does not update the labeling of the already distributed surgical masks (they are single-use, non-life-supporting/non-life-sustaining devices). - User exhaustion of already distributed surgical masks is described in Section V.C. of this guidance. - Even after the cessation of distribution, the manufacturer continues to submit any adverse event reports of which it becomes aware to FDA consistent with 21 CFR Part 803. ### Example 2 A continuous ventilator was authorized under the umbrella EUA for ventilators and ventilator accessories to support patients who develop respiratory distress due to COVID-19. On July 1, the advance notice of termination of the relevant EUA declaration is published. Before August 1, to help FDA plan for transition-related premarket review activities, the manufacturer submits an “EUA report” to the CDRH Document Control Center with “Attention: Notification of Intent” on the cover letter of the submission to inform FDA that it does not intend to pursue marketing authorization. This EUA report includes the information outlined in Section V.A. of this guidance, which includes the manufacturer’s plans to have already distributed ventilators remain distributed. On the EUA termination date (January 1), the relevant EUA declaration is terminated and the umbrella EUA is no longer in effect. On January 1, the manufacturer ceases distribution of the ventilator. FDA does not intend to object if the manufacturer implements a plan (that was included in the Notification of Intent) for the already distributed ventilators to remain distributed (e.g., ventilators in device distributors’ warehouses), including ventilators in the possession of end users (e.g., ventilators in healthcare facilities). As part of the plan, the manufacturer interacts with affected stakeholders, such as healthcare facilities, to determine the stakeholders’ interest in keeping distributed ventilators. The ventilator manufacturer updates the electronic labeling as outlined in Section V.C. of this guidance, and emails a copy of the electronic labeling to affected stakeholders that have expressed an interest in keeping the ventilators. The policies included in this guidance relate to the following actions by the device manufacturer and others: - The already distributed ventilators are not used. - Should healthcare facilities wish to retain the ventilator that lacks FDA clearance, approval, or authorization for use in the future, the future use of the device would be subject to the regulatory requirements of any future authorization, including marketing authorization or EUA. - For governmental stockpilers that wish to retain a device that lacks requisite FDA clearance, approval, or authorization for use in the future, FDA recommends engaging with the Agency to discuss the public health need for future deployment and/or use of the device in specific circumstances (e.g., regional natural disaster, localized disease outbreaks). - Even after the cessation of distribution, the manufacturer continues to submit any adverse event reports of which it becomes aware to FDA consistent with 21 CFR Part 803. ### Example 3 A non-traditional device manufacturer worked with a traditional device manufacturer (original equipment manufacturer (OEM)) to produce, as a contract manufacturer, ventilators that were designed by the traditional device manufacturer. Such devices were authorized under the umbrella EUA for ventilators and ventilator accessories and distributed by the OEM during the COVID-19 pandemic. On July 1, the advance notice of termination of the relevant EUA declaration is published. Before August 1, to help FDA plan for transition-related premarket review activities, the OEM submits an “EUA report” to the CDRH Document Control Center with “Attention: Notification of Intent” on the cover letter of the submission to inform FDA that it intends to pursue marketing authorization. This EUA report includes the information outlined in Section V.A. of this guidance. On October 1, the OEM submits a marketing submission to FDA. In its marketing submission, the OEM includes a “Transition Implementation Plan” for already distributed ventilators in the case of a positive decision as well as in the case of a negative decision on the marketing submission. On October 10, the marketing submission is determined to be administratively incomplete because it is missing a test report for a biocompatibility endpoint; the marketing submission is not accepted for review (an “RTA1 decision”). The OEM resolves the acceptance review deficiency by including the missing test report for the biocompatibility endpoint and resubmits the marketing submission on November 1. On November 8, the marketing submission is accepted for substantive review. On the EUA termination date (January 1), the relevant EUA declaration is terminated and the umbrella EUA is no longer in effect. The OEM has submitted a marketing submission and it was accepted by FDA. Under these circumstances, FDA does not intend to object to the continued distribution of the ventilators before FDA takes a final action on the marketing submission (see Section V.B.(2) of this guidance). Additionally, the OEM has kept the device labeling as described in the EUA-authorized device labeling. Under these circumstances, FDA does not intend to object to the device labeling not complying with applicable labeling requirements (see 21 CFR Part 801) where the device continues to be labeled as previously authorized under the EUA while the marketing submission is under FDA review (see Section V.B.(2) of this guidance). In this scenario, in the course of FDA’s substantive review, FDA identifies a potential control software issue that could result in patient harm. FDA issues a request for additional information and informs the OEM that the marketing submission is being placed on hold pending receipt of a response to the deficiency. The OEM updates its software, performs the appropriate testing, and provides additional information and a response to the deficiency. On July 10, the OEM receives a positive decision as part of FDA’s final action on the marketing submission. FDA and the OEM engage on the manufacturer’s Transition Implementation Plan to address already distributed devices, which includes the manufacturer updating software for already distributed ventilators and providing updated electronic labeling to the relevant stakeholders in accordance with the FDA-cleared version of the ventilator. The OEM continues to submit any adverse event reports of which it becomes aware to FDA consistent with 21 CFR Part 803. ### Example 4 A molecular diagnostic test kit manufactured by a commercial manufacturer was issued an individual EUA for the qualitative detection of nucleic acid from SARS-CoV-2 in upper and lower respiratory specimens in authorized laboratories. [^88] On July 1, the advance notice of termination of the relevant EUA declaration is published. On October 1, the manufacturer submits a marketing submission to FDA, which is accepted by the Agency. In its marketing submission, the manufacturer includes a “Transition Implementation Plan” for already distributed molecular diagnostic test kits in the case of a positive decision as well as in the case of a negative decision on the marketing submission. On the EUA termination date (January 1), the relevant EUA declaration is terminated and the EUA for the device is no longer in effect. The manufacturer has submitted a marketing submission and it was accepted by FDA. Under these circumstances, FDA does not intend to object to the continued distribution of the device before FDA takes a final action on the marketing submission (see Section V.B.(2) of this guidance). Additionally, the manufacturer has kept the device labeling as described in the EUA-authorized device labeling. Under these circumstances, FDA does not intend to object to the device labeling not complying with applicable labeling requirements (see 21 CFR Part 801) where the device continues to be labeled as previously authorized under the EUA while the marketing submission is under FDA review (see Section V.B.(2) of this guidance). #### a) Positive Decision In this scenario, the manufacturer receives a positive decision on February 20, as part of FDA’s final action on the marketing submission. FDA and the manufacturer engage on the manufacturer’s Transition Implementation Plan to address already distributed devices. The manufacturer does not update the device labeling for already distributed devices (these devices are single-use, non-life-supporting/non-life-sustaining devices); however, the manufacturer updates the device labeling for devices that are in production and those in its possession in accordance with the FDA-cleared version of the molecular diagnostic test kit. No outstanding issues were identified during FDA review that would result in a correction or removal of the molecular diagnostic test kits that were already distributed. The manufacturer continues to submit any adverse event reports of which it becomes aware to FDA consistent with 21 CFR Part 803. #### b) Negative Decision In this scenario, the manufacturer receives a negative decision on March 1, as part of FDA’s final action on the marketing submission. FDA and the manufacturer engage on the manufacturer’s Transition Implementation Plan to address already distributed devices. During FDA’s substantive review, FDA found that specific lots of the molecular diagnostic test kit had a high number of false positive reports, which may lead to a delay in both the correct diagnosis and treatment for the actual cause of a person’s illness. The manufacturer issues a voluntary recall for the affected lots of the molecular diagnostic test kit by informing relevant stakeholders to dispose of the affected lots. The policies included in this guidance relate to the following actions by the device manufacturer and others: - For unaffected lots of the molecular diagnostic test kit that are not subject to the recall and are already distributed, the devices remain distributed with device distributors and retail sellers who have already purchased the devices so that they may be used prior to the product expiration date. - The manufacturer has a small number of unaffected lots of the molecular diagnostic test kit that are not subject to the recall in its possession; the manufacturer does not distribute these devices. - The manufacturer does not update the device labeling of already distributed devices (these devices are single-use, non-life-supporting/non-life-sustaining devices); however, the manufacturer does communicate publicly about the recall about the affected lots of the molecular diagnostic test kit. - Even after the cessation of distribution, the manufacturer continues to submit any adverse event reports of which it becomes aware to FDA consistent with 21 CFR Part 803. --- [^14]: See sections 564(f)-(g) of the FD&C Act.
