Perkinelmer Inc. said the Vega is a first-of-its-kind preclinical ultrasound system that will accelerate preclinical research and drug development studies of cancer, cardiovascular, liver, kidney and other diseases. The imaging platform combines hands-free automation with high-throughput capability, which the company said is a major advance over manual ultrasound scanning across the bodies of individual lab mice.
The U.S. FDA’s draft device user fee agreement was months late in arriving on Capitol Hill, a fact which also delayed the public meeting on the draft, an event that finally took place April 19. The meeting kicked off with an acknowledgement by second-time FDA commissioner Robert Califf of the growing role of user fees in FDA finances, but Mark Leahey, president and CEO of the Medical Device Manufacturers Association (MDMA), said that the quality of FDA reviews was at least as important as the timeliness of those reviews even though the user fee deals include many deadline-based metrics.
The FDA has granted an emergency use authorization (EUA) to Inspect IR Systems LLC, of Frisco, Texas, for the company’s namesake test that evaluates the patient’s breath for the presence of volatile organic compounds (VOC) indicative of the SARS-CoV-2 virus. The test is expected to increase the volume of testing by only 64,000 per month at the current rate of production, however, making this a technological breakthrough of limited impact on the COVID-19 pandemic.
The FDA’s June 2021 draft guidance for remanufacturing of medical devices wades into a highly complicated area of compliance for third-party servicing organizations that may not be familiar with FDA regulations, but the draft has sparked another set of concerns. Two trade associations said the draft would seem to suggest that original equipment manufacturers (OEMs) must disclose confidential trade secrets to give these third parties the information needed to service these devices, a suggestion that both the Medical Device Manufacturers Association (MDMA) and the Advanced Medical Technology Association (AdvaMed) said is clearly out of bounds.
The U.S. FDA’s safety and performance-based pathway (SPBP) is intended as a leaner, meaner alternative to the conventional 510(k) pathway that would sidestep some of the presumed problems with the concept of substantial equivalence. The agency recently added four device types to this program, including orthopedic fracture fixation plates.
The FDA has given thumbs up to two clinical studies for a transcatheter aortic valve replacement (TAVR) system developed by HLT Inc. to treat aortic stenosis among high-risk patients. Those studies will include aortic regurgitation which also occurs when an aortic valve doesn't open and close tightly enough but for which there are few suitable, noninvasive treatments.
Clinicians are still at liberty to use medical products outside the labeled indication for use, but the U.S. FDA believes radiologists may be unaware of the limitations of radiological computer-aided triage and notification (CADt) software for intracranial large-vessel occlusion (LVOs). The agency advised clinicians that these programs are not intended for use as a substitute for radiologist review of images, but instead should be used only to flag suspect images as part of an effort to triage these patients.
Acquisitions in the diagnostics space incurs some interesting liabilities, given recent case law regarding subject matter eligibility, but this is not the only trap door for the acquiring company. Roche Diagnostics Corp., of Indianapolis, managed to avoid an induced patent infringement charge by Meso Scale Diagnostics LLC in a recent hearing at the U.S. Court of Appeals for the Federal Circuit in connection with Roche’s 2007 acquisition of Bioveris Corp.
As part of a series of guidances addressing clinical trial diversity, the U.S. FDA issued a draft guidance April 13 focused on improving enrollment of participants from underrepresented racial and ethnic populations.
The FDA program for third-party review of 510(k) applications was designed to take some of the load off the agency’s review staff and thus allow the agency to focus on more complex filings, but recent data suggest that the program has had only a modest effect on the FDA’s workload. The number of third-party reviews for the current and two previous fiscal years only modestly exceed the numbers from fiscal years 2018 and 2019, a conspicuous trend given the distractions at the FDA’s device arising from its work to manage the COVID-19 pandemic.
