With the advent of wearable digital health technologies, patient-generated health data (PGHD) will play an increasingly central role in evidence generation for medical device companies. Speakers on a recent FDA workshop advised that there are several barriers to the use of PGHD for evidence generation, however, such as the perennial headache of data interoperability and a new twist on the question of patient trust, problems that are likely to plague the field for the foreseeable future.

With paralysis affecting more than 5 million Americans, devices that serve as brain-computer interfaces (BCIs) are increasingly important, even if few are commercially available. The FDA has responded to the predicament with a leapfrog guidance, a preliminary form of guidance designed to foster more interaction with industry and encourage developers to move along on development programs for devices that will aid patients in restoring lost motor and/or sensory capabilities.

Fractyl Health Inc. closed $100 million in new financing Wednesday to expand and accelerate clinical development efforts to reduce dependence on insulin among type 2 diabetes patients. The startup, which changed its name from Fractyl Laboratories Inc., will use the financing to support additional late-stage clinical studies for determining the potential of its Revita DMR.

The controversy over the use of paclitaxel in devices for the peripheral vasculature has taken a significant bite out of sales, but a new study serves to help reverse the narrative regarding mortality. According to a study of more than 168,000 Medicare patients, stents and angioplasty balloons coated with paclitaxel (PTX) were non-inferior to non-coated devices for mortality out to nearly three years, a finding that may encourage clinicians to return to normal utilization patterns and thus help to restore sales volumes.

Hemex Health Inc.’s newborn screening for sickle cell disease substantially reduces the labor involved for parents and providers in testing for the potentially fatal condition. The test had previously been able to test infants 6 weeks and older on the company’s Gazelle platform.

Neovasc Inc. has hit pause on its Tiara transfemoral mitral valve replacement (TF) program and is cutting its workforce by more than 40%, citing the additional time and substantial investment required to develop the program and the associated costs. The changes are expected to extend its cash runway from about 18 months to more than three years. The changes were implemented with about 18 months to remain solvent as part of a series of actions to focus on enhancing current shareholder value and focusing investments on near-term value drivers, namely the Reducer stent and the Tiara transapical mitral valve replacement (TA) system.

The FDA’s multiyear effort to rewrite the Quality System Regulation (QSR) to align with ISO 13485 could significantly ease the regulatory burden for device makers in multiple markets, but that effort has floundered over the past couple of years. The associated rulemaking is back on the FDA’s agenda, signaling that device makers might soon be able to deploy a single and relatively inexpensive quality management system, which in principle would significantly reduce their compliance costs.

10x Genomics Inc. began distribution of its new Visium Spatial Gene Expression for FFPE (formalin-fixed and paraffin-embedded) assay in the U.S., giving researchers access to whole transcriptome spatial gene expression across entire FFPE tissue samples. The assay allows researchers to overcome the challenges in transcriptome analysis created by FFPE processing.

The FDA issued a June 10 warning letter to Innova Medical Group Inc. in connection with the company’s rapid antigen tests for the SARS-CoV-2 virus, an action that accompanies a class I recall and a safety communication.

Of all the controversies surrounding the FDA, the agency’s reliance on user fees and its use of accelerated review of therapies might be the most consistent sources of public angst. Coleen Klasmeier, a partner of Sidley Austin LLP, told BioWorld that while she is not particularly concerned about regulatory capture stemming from FDA reliance on user fees, it may be appropriate to ask whether the drug premarket review process leaves FDA staff with more confidence in a new drug application than the data would seem to suggest.
