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The U.S. FDA reported that 28 serology tests for antibodies for the SARS-CoV-2 virus either have been withdrawn from the market by the sponsor or delisted by the agency for failure to comply with its notification process for emergency use authorization (EUA).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

Of the 160 biopharma deals tracked by BioWorld during the month of April, 36% are for collaborations focusing on the development of therapeutics and vaccines for COVID-19.

LONDON – Human challenge specialist Open Orphan plc has raised £12 million (US$14.6 million) in a placing to accelerate development of COVID-19 challenge study models, to meet demand from vaccines and therapeutics developers worldwide.

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.

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.
