The U.S. FDA reported that 28 serology tests for antibodies for the SARS-CoV-2 virus either have been withdrawn from the market by the sponsor or delisted by the agency for failure to comply with its notification process for emergency use authorization (EUA). The agency said the list of unavailable tests will be updated over time. For his part, Commissioner Stephen Hahn said the move was undertaken “to ensure that Americans have access to trustworthy tests.”

Mammoth Biosciences Inc., of South San Francisco, and London-based Glaxosmithkline plc (GSK) have joined forces to develop a point-of-care test to detect active COVID-19 infections using Mammoth’s CRISPR-based DETECTR platform. The two companies hope to submit an application to the U.S. FDA for emergency use of the test before the end of the year.

The pandemic-driven FDA guidance for device shortages addressed a topic that has been discussed for devices for some time despite lack of congressional action, but shortages may be ordinarily interpreted as a consequence of reduced or terminated production that crimps supplies. That interpretation has been expanded for the duration of the COVID-19 pandemic, however, to include circumstances in which demand exceeds supply even when the manufacturer sustains normal production levels, in which case the manufacturer is liable for reporting the shortage to the FDA.

Like many other med-tech companies, Medtronic plc, of Dublin, saw COVID-19 affect its financial results for its fourth quarter and fiscal year 2020, as procedures were deferred in the wake of the pandemic.

Ortek Therapeutics Inc., of Roslyn Heights, N.Y., has officially launched its electronic early cavity detection system, the Ortek-ECD. The U.S. FDA-cleared device can detect dental lesions before they show up on X-rays, enabling less invasive treatment and preventing greater damage to the tooth structure. Ortek holds the exclusive license for the device which was developed at Stony Brook University School of Dental Medicine.

Proscia Inc., a Philadelphia-based company that focuses on artificial intelligence (AI)-enabled digital pathology solutions, recently made the Concentriq Dx digital pathology software available for use in reviewing and reporting of digital pathology slides in the U.S. during the COVID-19 pandemic.

Dry eye disease is a common problem, and Sight Sciences Inc., of Menlo Park, Calif., is looking to help those who suffer from the condition. Now, the company has seen the presentation of positive clinical data from the multicenter OLYMPIA study of Tearcare, which the company has heralded as the first wearable and intelligent eyelid technology for dry eye treatment.

Abbott Laboratories’ ID Now test for the SARS-CoV-2 virus made waves when it was introduced thanks to the rapid turnaround time the molecular test promised. But questions about the test’s performance have surfaced several times in recent weeks. The latest criticism comes from a study conducted at the New York University Langone Medical Center, which claims the diagnostic compared poorly against a competitor. However, the U.S. FDA said that it has questions about the swabs and transport media used in connection with the test. As a result, it will stand pat regarding the ID Now’s place in the emergency use authorization (EUA) program.
