Wall Street has stabilized enough after the recent pandemic-induced volatility to offer enthusiastic support to a med tech generating significant revenue that already reached breakeven during the first quarter. Inari Medical Inc. priced its IPO at the top of an already upwardly revised range to raise $156 million. It sold 8.2 million shares at $19, above the prior range of $17 to $18. Shares of the Irvine, Calif.-based company (NASDAQ:NARI) then more than doubled to hit about $43 on its first day of trading.

The U.S. FDA reported that 28 serology tests for antibodies for the SARS-CoV-2 virus either have been withdrawn from the market by the sponsor or delisted by the agency for failure to comply with its notification process for emergency use authorization (EUA).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.”

Scaling up to manufacture a massive volume of a COVID-19 vaccine, drug or innovative device that’s still in early stage development is easier said than done, especially in a global pandemic that has the supply chain stretched beyond capacity.

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. Quarterly worldwide revenue came in at $5.998 billion, representing a decrease of 26% as reported and 25% on an organic basis.

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.
