The U.S. FDA’s device user fee schedule doubled for both the third and fourth user fee agreements over the prior iterations, but the pressure against another doubling for the fifth iteration of the user fee program is mounting.

The U.S. FDA has granted 510(k) clearance to Siemens Healthineers AG for AI-Rad Companion Organs RT, the newest module in its platform of artificial intelligence-based software assistants. The radiation therapy planning aide joins earlier AI-Rad Companion modules for interpreting magnetic resonance imaging (MRI) studies of the brain and prostate, as well as one for chest computed tomography (CT) studies.

Kantaro Biosciences LLC, a joint venture between the Mount Sinai Health System and RenalytixAI, has received emergency use authorization from the U.S. FDA for its semi-quantitative SARS-CoV-2 IgG antibody test kit. Known as COVID-Seroklir, the test determines the presence and precise level of IgG antibodies. It has demonstrated 98.8% sensitivity and 99.6% specificity for detecting SARS-CoV-2 specific IgG antibodies against two virus antigens, the full-length spike protein and its receptor-binding domain.

Hologic Inc. has gained approval from the U.S. FDA to add a diagnostic claim to its HIV type 1 viral load monitoring assay. This makes the Aptima HIV-1 Quant Dx assay the first dual-claim assay in the U.S., allowing both viral load monitoring and diagnosis. For laboratories that use the assay, the dual claim allows for consolidated testing on one automated platform, adding to efficiency.

The U.S. FDA cleared Alivecor Inc.'s Kardia AI V2 interpretive electrocardiogram (ECG) algorithm for use in its personal ECG app and devices.

An antibody cocktail developed by Regeneron Pharmaceuticals Inc. has received emergency use authorization (EUA) from the FDA for the treatment of mild to moderate COVID-19.
