 supported by more detailed and comprehensive scientific evidence, including clinical data, to demonstrate the safety and efficacy of the IVD for its intended purpose. If the device is determined to present a “significant risk,” the sponsor may not begin a clinical trial until it submits an investigational device exemption (IDE) to the FDA and obtains approval to begin the trial. 

After the PMA application is submitted, the FDA has 45 days to make a threshold determination that the PMA application is sufficiently complete to permit a substantive review. If the PMA application is complete, the FDA will file the PMA. The FDA is subject to a performance goal review time for a PMA application that is 180 days from the date of filing, although in practice this review time is longer. Questions from the FDA, requests for additional data including additional clinical data and referrals to advisory committees may delay the process considerably. The total process may take several years and there is no guarantee that the PMA application will ever be approved. Even if approved, the FDA may limit the indications for which the device may be marketed. New PMA applications or PMA supplements may be required for modifications to the manufacturing process, labeling, device specifications, materials or design of a device that is approved through the PMA process.

Regulation of Companion Diagnostic Devices

If a sponsor or the FDA believes that a diagnostic test is essential for the safe and effective use of a corresponding therapeutic product, the sponsor of the therapeutic product will typically work with a collaborator to develop an IVD companion diagnostic device. The FDA has issued a final guidance document entitled “In Vitro Companion Diagnostic Devices” that is intended to assist companies developing in vitro companion diagnostic devices and companies developing therapeutic products that depend on the use of a specific in vitro companion diagnostic for the safe and effective use of the product. In the guidance, the FDA defined an IVD companion diagnostic device as a device that provides information that is essential for the safe and effective use of a corresponding therapeutic product. The FDA also noted that in some cases, if evidence is sufficient to conclude that the IVD companion diagnostic device is appropriate for use with a class of therapeutic products, the intended use/indications for use should name the therapeutic class, rather than each specific product within the class. In April 2020, FDA published another final guidance entitled “Developing and Labeling In Vitro Companion Diagnostic Devices for a Specific Group or Class of Oncology Therapeutic Products” that expands on the idea of a class of therapeutic products. The latter guidance describes considerations for
