Manufacturers should work diligently to transition medical devices

The Secretary of the Department of Health and Human Services (HHS), Xavier Becerra, has extended the Public Health Emergency (PHE) for the twelfth time on January 11, 2023, as a consequence of the Coronavirus Disease 2019 (COVID-19) pandemic.[1] As a result, liability protections granted to medical device manufacturers by virtue of this declaration will continue for now. However, once this declaration is ended, medical device manufacturers who received such protections will need to consider what actions they will need to take in order to insure that their products can lawfully remain on the market. This article addresses the strategies and considerations medical device manufacturers should take in preparation for the termination of the COVID-19 pandemic and PHE to ensure a smooth transition of their devices on the market back to the pre-COVID-19 regulatory scheme.

Former HHS Secretary Alex Azar initially declared the PHE on January 31, 2020, nationwide, [2] pursuant to section 319 of the Public Health Service Act.[3] Termination of the PHE is determined upon the Secretary declaring that the emergency no longer exists, or upon the expiration of the 90-day period beginning on the date on which the determination is made by the Secretary, whichever occurs first.[4] The renewed PHE is effective through April 11, 2023, unless terminated by the Secretary sooner.  HHS has indicated it will give at least a 60-day notice of termination before the PHE ends.[5] This notice would need to occur between now and March 12, 2023.  Whether the PHE is renewed for the thirteenth time depends on a multitude of factors and COVID-19 circumstances, but many believe that the end of the pandemic may be in sight sometime this year. 

Once the PHE was declared, the U.S. Food and Drug Administration (FDA or “Agency”), to foster the development and availability of medical products that would assist in combating the pandemic, issued Emergency Use Authorizations (EUAs) to certain device manufacturers to encourage innovation and manufacturing of products that, among other things, would provide protection from and treatment for the COVID-19 virus. These EUAs allow manufacturers to market and distribute unapproved medical products, or allow an unapproved use of an approved medical product in certain situations. The EUAs, issued by the FDA pursuant to section 564(b) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)[6] and ensuing guidances, altered the usual standards and enforcement policies to help expand the availability of medical products during the time of the PHE. Once the COVID-19 PHE comes to an end, however, the FDA will revert to its normal operations, whereby all stakeholders, including device manufacturers, healthcare facilities, healthcare providers, patients, and consumers will need to adjust from policies adopted and implemented during the declared COVID-19 PHE back to pre-PHE times. 

Emergency Use Authorization
Section 564 of the FD&C Act (21 U.S.C. 360bbb-3) authorizes the FDA to issue EUAs,[7] once the Secretary declares that an EUA declaration is appropriate.[8] Shortly after the initial declaration of the COVID-19 PHE, the Secretary of HHS also determined that “there is a public health emergency that has a significant potential to affect national security or the health and security of United States citizens living abroad,”[9] involving the virus that causes COVID-19, now known as SARS-CoV-2, thereby justifying the emergency use of medical devices and in vitro diagnostics for detection, diagnosis and/or treatment of SARS-CoV-2. Just in the year following the EUA declaration, the FDA reviewed over 2,300 EUA requests and issued more than 600 EUAs for medical countermeasures to combat COVID-19.[10]

Termination of an EUA declaration
Unlike the section 319 PHE declaration that expires if not extended, an EUA declaration under section 564 generally continues until the HHS Secretary terminates it. Thus, an EUA may remain in effect beyond the duration of the PHE. The HHS Secretary can terminate an EUA declaration on the earlier determination by the HHS Secretary that “the circumstances that precipitated the declaration have ceased (after consultation as appropriate with the Secretary of Homeland Security or the Secretary of Defense),” or “a change in the approval status of the product such that the authorized use(s) of the product are no longer unapproved (section 564(b)(2)),”[11] as in the case of an unapproved product distributed and used under an EUA that was subsequently approved by the FDA for the use allowed by the EUA. The Secretary shall provide advance notice that a declaration will be terminated and “the period of advance notice shall be a period reasonably determined”[12] to allow sufficient time for the disposition and transition of the unapproved product. The FDA has suggested the period of advance notice be 180 days before the day on which the EUA declaration is terminated.[13],[14]

Enforcement discretion
The FDA creates, implements and enforces its regulations, which are based on the laws set forth in the FD&C Act or other laws under which the Agency operates. These regulations have the full force of law. However, the FDA, as well as other government agencies, may choose to apply enforcement discretion as in the case where a medical product falls under the regulatory scheme of medical devices within its purview, but the FDA chooses not to enforce the requirements when the risk to patients is low.[15] Thus, while the legal obligations of the FDA in overseeing and regulating drugs and medical devices remain in effect technically, the Agency may issue enforcement policies to inform the public that it will not seek to enforce certain provisions of the statutes in enumerated situations under the COVID-19 PHE and EUA declarations.[16] During the COVID-19 PHE, the FDA issued a number of guidances outlining its enforcement policies concerning medical devices to address supply issues and ensure access to care, and to give health care providers the flexibilities needed to respond to COVID-19 and help keep people safer.[17],[18] For example, these guidances typically recite an enforcement policy indicating that the “FDA does not intend to object to modifications to the indications or design of FDA cleared or approved devices … without prior submission of a premarket notification or premarket approval application supplement where the modification does not create an undue risk in light of the public health emergency.”[19] The FDA applied enforcement discretion to numerous other medical devices such as ventilators, in vitro diagnostics, sterilizers, infusion pumps and digital health devices, among others.[20]

Transitioning medical devices
It is not clear when the COVID-19 PHE declaration or the EUA declaration may end, but as discussed above, the Secretary of HHS is required to provide advance notice of termination of the PHE[21] and EUA.[22] In preparation for transitioning medical devices back to pre-EUA normal operations, the FDA issued two draft guidances (“transition guidances”) directed at device manufacturers, healthcare facilities, healthcare providers, patients, consumers and FDA “to adjust from policies adopted and operations implemented during the declared COVID-19 [PHE] to normal operations.”[23],[24] The key features outlined in these transition guidances include:

• The timeline for withdrawal of the enforcement policy guidances issued during the COVID-19 PHE and the advance notice of termination of each EUA issued during the EUA declaration
• Manufacturer notice of intent to distribute its device after withdrawal of the enforcement guidances
• Submissions of marketing applications prior to EUA termination date
• Products continued to be marketed after EUA termination 

The FDA anticipates the final transition guidances will likely be issued early 2023. It is highly advised that manufacturers carefully consider strategies and options for transitioning their medical devices when the relevant EUAs and COVID-19-enforcement policies cease to be in effect. While these most likely will terminate at the same time, an EUA declaration under section 564 may remain in effect beyond the duration of the PHE.

Timeline
The FDA is proposing a 180-day transition period beginning on the “implementation date” and ending on the date enforcement guidances are withdrawn.[25] The FDA lists 17 enforcement policies that will be effected by the draft guidance.[26] The transition plan is a phased approach allowing manufacturers to become compliant with applicable statutory and regulatory requirements once the policies are no longer in effect and the more stringent requirements are reinstated. Manufacturers are still expected to comply with all statutory and regulatory requirements applicable to their devices, such as adverse event reporting requirements, during this period under 21 CFR Part 803, and submit reports consistent with FDA guidance,[27] and, if not already doing so, prepare marketing submissions if applicable. The FDA also proposes a similar timeline for termination of EUAs whereby advance notice of the “EUA termination date” will be published in the Federal Register 180 days before the EUA declaration is terminated.[28] Manufacturers also must continue to comply with the terms of the device’s EUAs as well as statutory and regulatory requirements applicable to their devices following the notice of the termination date. 

Notifications of intent and transition implementation plan
The FDA recommends medical device manufacturers notify the Agency whether or not they intend to submit a marketing application to continue distributing their devices after the termination date. It also encourages that communications with the Agency begin early and that the “Notifications of Intent” be submitted within 90 days following notice of termination. If a manufacturer does not intend to continue to distribute its device, it should follow 21 CFR Part 806 for the reporting requirements of any correction or removal of a medical device(s). The Agency does note that it will not object (i.e., apply its enforcement discretion) to the disposition of certain devices, such as single use and reusable non-life-supporting/non-life-sustaining devices that were distributed prior to the guidance withdrawal or EUA termination date. However for reusable devices, the device should be restored to the previously FDA-cleared or approved version of the device, or have publicly available labeling that accurately describes the product features and regulatory status (i.e., device lacks FDA clearance or approval). For life-supporting/life-sustaining devices, the FDA recommends devices should have both publicly available and a physical copy of the labeling.[29] In vitro diagnostic devices that remain distributed are to be used no more than two years after the EUA termination date or until the expiration date, whichever is less.[30]

For manufacturers planning to continue to distribute medical devices after the termination date, a marketing application should be submitted to the FDA allowing sufficient time to get through the “refuse to accept” process for 510(k) medical devices[31] and/or the “acceptance and filing review” process for premarket approvals[32] or De Novo classification requests[33] before the termination and withdrawal date. Marketing submissions are expected to be submitted to the Agency and approved prior to the withdrawal of the enforcement guidances. The FDA describes hypothetical scenarios to illustrate the policies outlined in the transition guidances. A key recommendation for manufacturers to include in their marketing submissions is a “transition implementation plan” that addresses the manufacturer’s plan for devices already distributed in the case of a positive or negative Agency decision.[34]  The Agency notes that it will not object to the continued distribution of devices as long as the manufacturer’s marketing submission has been submitted to and accepted by the FDA before the EUA termination date and the FDA has not taken a final action on the marketing submission.[35]  In cases where a manufacturer receives a negative decision from the FDA on its marketing submission for a product that has been distributed under an EUA prior to the termination date, the transition implementation plan is recommended to include:[36]

• An estimated number of devices that are currently under an EUA in distribution in the U.S.
• A manufacturer’s benefit-risk based plan and explanation for disposition of already distributed devices
• A description of the process for notifying patients, consumers, healthcare facilities, healthcare  providers and distributors of the device’s regulatory status (i.e., device lacks FDA clearance or approval)
• A description of the process and timeline for restoring distributed devices to the previously FDA-cleared or approved version of the devices, with publicly available labeling (and a physical copy if applicable)
• A description of the maintenance plan for distributed devices

For manufacturers receiving a positive decision on their marketing submission, the transition implementation plan should include:[37]

• An estimated number of devices that are currently under an EUA in distribution in the U.S.
• A description of the process for notifying patients, consumers, healthcare facilities, healthcare providers and distributors of the device’s regulatory status (i.e., FDA cleared or approved)
• A description of the process and timeline for providing to users of previously distributed devices updated labeling or components that reflect any changes made to the cleared or approved device

Although the FDA provides hypothetical scenarios to exemplify the timeline and expectations of the transition policy, it also recognizes that there may be unique situations raising compliance issues not covered.  To that extent, the Agency suggests manufacturers to initiate discussions through the Q-Submission Program (including Pre-Submissions) in order to develop a plan to address specific scenarios.[38]  As with all FDA guidance, these draft transition guidances — when finalized — will contain nonbinding recommendations and represent the FDA’s current view on the topic, but does not have the force and effect of law.

Conclusion
The COVID-19 pandemic will come to a welcomed end. As the supply chain crisis eases, the need for emergency measures will diminish, the continuity of patient care will be restored, and the burdens on our health care system will decrease. The FDA believes an orderly and transparent transition is appropriate for devices that fall within the scope of its guidances and encourages manufacturers to work toward a marketing submission before the termination date. The Agency intends to help facilitate this process by working with manufacturers during this transition period to avoid exacerbating product shortages and supply chain disruptions. The PHE and EUA declarations will terminate at some point and it is incumbent on manufacturers to work diligently to transition their medical devices in a timely manner without overwhelming FDA resources. In the post-COVID-19 PHE/EUA era, the FDA will likely increase the scrutiny of medical devices to assure proper transitioning  and to protect the public health by ensuring safety and efficacy. The FDA recognizes that continued flexibility is necessary, while still providing necessary oversight, and expects manufacturers to prepare early.
