LONDON – Sirakoss Ltd. has received FDA 510(k) clearance for its nanoparticle synthetic bone graft substitute, after showing the ready-to-use putty is equivalent to the CE-approved dry formulation. Rather than granules that are mixed with a patient’s blood before administration, the inorganic calcium phosphate-based Osteo³ Zp putty consists of the granules suspended in a fully synthetic resorbable carrier.

The number of tests of various types for the SARS-CoV-2 virus are still growing, but the emergency use authorization (EUA) program is not the only option for developers. Timothy Stenzel, director of the Office of In Vitro Diagnostics and Radiology, said on the agency’s May 27 town hall that the agency would like to see test developers file for a 510(k) for their tests when the data are sufficient to support an application, adding that any such clearances will not affect the U.S. FDA’s interest in keeping plenty of similar tests on the market via the EUA mechanism.

PERTH, Australia – Perth-based regenerative medicine company Orthocell Ltd. has submitted a 510(k) application to the U.S. FDA for its Celgro collagen medical device for dental guided bone and soft tissue regeneration applications.

With the COVID-19 pandemic overwhelming hospitals and treatment centers, San Jose, Calif.-based Outset Medical Inc. scored a big win with U.S. FDA clearance of its Tablo hemodialysis system for home dialysis use.

Charleston, S.C.-based startup ABM Respiratory Care has received U.S. FDA clearance for its first product, an airway clearance system known as Biwaze Cough.

Erlangen, Germany-based Siemens Healthineers AG has secured U.S. FDA clearance for its Rapidpoint 500e blood gas analyzer. Available in CE mark countries since August 2019, the device is used to monitor respiratory distress in critically ill patients, such as those in acute care due to COVID-19.

Pear Therapeutics Inc. obtained FDA approval for Somryst, the first prescription digital therapeutic for chronic insomnia. The app provides structured cognitive behavior therapy (CBT) with clinical dashboards for physicians. While CBT is the recommended first-line therapy for insomnia, the U.S. has only 500 therapists certified to provide CBT for insomnia (CBTi) for the estimated 30 million Americans who suffer from chronic difficulty going to and staying asleep.

LONDON – Behold.ai Ltd. has secured U.S. FDA 510(k) approval for use of its Red Dot image recognition algorithm in the automatic diagnosis of life-threatening pneumothorax (collapsed lung).

Medical devices are known to be iterative, but so are FDA guidances, and the 2018 draft guidance for third-party review of 510(k) applications was the second such document in two years. The 2020 final guidance made another adjustment or two based on feedback from industry, including a specific note that the intent of the guidance is to eliminate any need for routine FDA re-review of 510(k)s reviewed by third parties.

The U.S. FDA has finalized two guidances dealing with class II tests that are subject to Medicare regulations, including the so-called dual CLIA waiver guidance. The agency said it will hold an April 14, 2020, webinar to go over both guidances, allocating 90 minutes to deal with questions about the two documents.
