Vagus nerve stimulation (VNS) researchers notched another success with FDA approval of a drug-free rehabilitation system that uses the technology to help patients who have lost mobility in their hands and arms as a result of ischemic stroke regain function. Microtransponder Inc.’s Vivistim pairs rehabilitation exercises with VNS to enhance their impact. The clinical study evaluated by the FDA for the system's approval showed that Vivistim doubled the improvement in upper extremity motor function compared to supervised rehabilitative exercises alone at six weeks and 90 days.

The FDA has issued an emergency use authorization (EUA) for Becton, Dickinson & Co.’s (BD) Veritor At-Home COVID-19 test – a rapid COVID-19 digital antigen test. The test, which is designed for home use, uses a mobile app from Los Angeles-based Scanwell Health Inc. that provides instructions on how to collect and transfer the nasal swab sample to the test stick. The smartphone camera is then used to capture, analyze and interpret results within 15 minutes. BD said it will initially be rolled out to businesses, schools and governments looking to provide a self-testing option.

Helius Medical Technologies Inc. has received an FDA breakthrough device designation for its Portable Neuromodulation Stimulator (Pons) device for temporary treatment of dynamic gait and balance deficits due to stroke.

The wave of home-use tests for the COVID-19 pandemic has amplified the question of how device makers might validate such a test, but there is also the question of how to convert a device from prescription-only (Rx-only) use to over-the-counter (OTC) status to consider. The FDA has provided an update on OTC devices, which indicates that a conversion from prescription-only use to OTC use will require usability testing and a new regulatory filing, but the update conflicts with the agency’s own policy on changes to a device undertaken only to convert the label from prescription to OTC use.

The FDA has posted an advisory regarding robotically assisted surgery (RAS) for mastectomy, but the agency also pointedly noted that it is aware of studies underway for such indications without the appropriate oversight. The FDA did not name Intuitive Surgical Inc. in the notice, but the company nonetheless responded to the FDA statement by confirming the absence of any devices thus approved or cleared. The FDA had previously issued a Feb. 28, 2019, advisory stating that the safety and efficacy of RAS devices for mastectomy and the prevention or treatment of breast cancer had not been established.

The FDA has approved Medtronic plc’s Evolut FX TAVR system for patients with symptomatic severe aortic stenosis. During Medtronic’s fiscal first quarter earnings call CEO Geoffrey Martha said the company will roll the latest generation system out in the U.S. market later this year, with a full launch planned in 2022.

The FDA has granted full approval to Pfizer Inc.’s COVID-19 vaccine in a move that is hoped will convince unvaccinated citizens that the shot is safe and effective. The mRNA vaccine, which will be branded as Comirnaty and was first developed by Germany’s Biontech SE, has been available since Dec. 11 last year under an emergency use authorization (EUA) and is the first to receive the FDA’s full endorsement.

The FDA said it has withdrawn the accreditation of Accelerated Device Approval Services LLC (ADAS), of Miami, for making false presentations about one of the company’s employees. Among the allegations are that the company named a reviewer who was never employed by ADAS, and that the company misled a client about the status of a regulatory filing.

The FDA’s pre-IND response to Virpax Pharmaceuticals Inc.’s MMS-019, a molecular masking spray being developed as an over-the-counter product to limit transmission of SARS and influenza, has the company breathing easier and ready to chase an NDA. Virpax is in a crowded field of 43 COVID-19 intranasal therapeutics and vaccine programs.

The FDA’s emergency use authorization (EUA) program is still active in the area of tests and test kits, which is due in part by the emergence of the Delta variant of the SARS-CoV-2 virus and the associated warnings that the effectiveness of vaccines may be declining. One example of the sustained emphasis on testing is the EUA granted to Thermo Fisher Scientific Inc. for two PCR test kits that can detect the latest variants of the virus, a demonstration that the demand for these updated tests seems unlikely to ebb anytime soon.
