Accreditation Scheme for Conformity Assessment (ASCA)

The Accreditation Scheme for Conformity Assessment (ASCA) will be a pilot program under the  CDRH Standards and Conformity Assessment Program. The ASCA Pilot Program aims to enhance the predictability of the medical device review process by reducing premarket questions in areas where current conformity activities result in inconsistent testing practices, conformance declarations, and regulatory review. ASCA is intended to increase the consistency of submissions, saving FDA resources in the review of certain testing.  

The ASCA Pilot Program will also promote the development and recognition of consensus standards and improve post market safety and performance evaluation due to a greater understanding during premarket review of how a device was tested and evaluated.

The Medical Device User Fee Amendments (MDUFA IV) commitment letter states that the pilot will ensure appropriate interaction between the FDA, accreditation bodies, and testing labs.

How is the FDA developing the ASCA Pilot Program?

ASCA emerged from discussions with device manufacturers during negotiations for MDUFA IV and was included in section 514(d) of the FD&C Act. Participants agreed that this approach has the potential to significantly promote the use of consensus standards, reduce burden on manufacturers, and enhance conformity assessment processes.  

To establish the framework, procedures and requirements of the ASCA Pilot Program, and as part of MDUFA IV commitments, the FDA has solicited input through a Federal Register notice (May 2017), a public workshop (May 2018), and many other discussions and outreach opportunities. The FDA continues to develop the ASCA Pilot Program scheme and stakeholders will have additional opportunities to provide suggestions. In particular, we plan to publish a draft guidance by the end of fiscal year 2019 and seek public comment at that time. The guidance will include more specific information about participation in and operation of the ASCA Pilot Program.

Why is the FDA implementing the ASCA pilot program?

ASCA capitalizes on the relevance of consensus standards in device development and regulatory review. The FDA and industry agreed during MDUFA IV negotiations that an accreditation program has the potential to improve device premarket review, especially standards conformity assessment activities. The FDA  intends to establish the ASCA Pilot Program to fulfill the FDA MDUFA IV commitment and the corresponding statutory requirements added by section 205 of the FDA Reauthorization Act of 2017.

What may be the benefits of ASCA?

The ASCA Pilot Program is intended to minimize the need to submit complete test reports and reduce the number of additional information requests.

How does the FDA envision the ASCA Pilot Program working?

Under the ASCA Pilot Program, the FDA will define a conformity assessment scheme describing the interactions between and specifications for accreditation bodies and testing labs. Similar to other types of third party accreditations, the scheme will outline a process for participation by accreditation bodies and testing labs and suspension or withdrawal of poorly performing participants. To promote transparency, the FDA intends to publicly post information on the FDA’s website about ASCA testing labs, including the FDA-recognized consensus standards for which they are accredited.

Which standards are likely to be included in the ASCA Pilot Program?

The FDA is currently determining the standards to be included in the ASCA Pilot Program. As noted above, the FDA has consulted with stakeholders as part of this process and identified a potential series of standards for initial consideration. Per the FDA MDUFA IV commitment, the Pilot Program will include a minimum of five appropriate FDA-recognized consensus standards, at least one of which will be device-specific. During the public workshop, presentations and discussions focused on standards from the following areas:

  • Biological evaluation of medical devices
  • Basic safety and essential performance of medical electrical equipment, medical electrical systems and laboratory equipment

The FDA will announce the standards which are part of the ACSA Pilot Program at a future date.

Are there plans to expand the number of standards included in the ASCA Pilot Program?

Expanding the standards included in the ASCA Pilot Program will depend on several factors. The FDA intends to provide annual reports on the progress of the ASCA Pilot Program and work with stakeholders to identify improvements, including consideration for expansion. Under section 514(d)(4) of the FD&C Act, the program will sunset October 1, 2022. However, if the pilot establishes the value of the program, it may become permanent. The FDA expects to add more standards if and when the ASCA Pilot Program becomes permanent.

When does the FDA expect to launch the ASCA Pilot Program?

In accordance with section 514(d)(3)(C) of the FD&C Act, the FDA must initiate the ASCA Pilot Program no later than September 30, 2020. The FDA is working to launch the pilot program as soon as possible and before that date.
