The run on at-home COVID-19 tests may be for naught. The FDA warned that the popular rapid antigen tests recommended to keep New Year’s Eve revelers, relatives visiting elderly grandparents and workers exposed to the coronavirus from spreading COVID-19 are less likely to detect the Omicron variant than earlier strains of the virus. “Early data suggest that antigen tests do detect the Omicron variant but may have reduced sensitivity,” the agency said in an update on Dec. 29. Despite the higher rate of false negatives, the FDA said individuals should continue to use the tests. Those experiencing symptoms or with a high likelihood of infection based on exposure should follow-up with a molecular test if their antigen test returns a negative result.

The Verifying Accurate Leading-edge IVCT Development (VALID) Act seems poised for passage in 2022, a bit of welcome relief for those stuck in the regulatory twilight world of the lab-developed test (LDT). However, Carly McWilliams, director of regulatory policy for North America for Roche Inc., said recently at the recent Food and Drug Law Institute enforcement meeting that the VALID Act is likely to leave the question of a user fee schedule for a future Congress, given that the associated rulemaking, guidance development and compliance activities are likely to consume the better part of, if not the entirety of, the next five years.

As global demand for rapid testing soars due to a new variant of COVID-19, one company is shaking up the diagnostics market with an at-home rapid PCR solution. Founded in 2017 by scientist and entrepreneur Jonathan Rothberg, Detect Inc. is the developer of Detect COVID-19, a direct-to-consumer PCR test that provides results within one hour.

French remote monitoring and software startup Implicity SAS won FDA clearance for its ILR ECG Analyzer, a medical algorithm that analyzes electrocardiogram data from implantable loop recorders (ILRs). The company plans to launch the artificial intelligence (AI)-powered algorithm, which also is CE marked, in both the U.S. and Europe beginning next month.

Announcements of new radiology solutions enhanced by artificial intelligence (AI) and machine learning appeared almost daily in 2021, all promising more accurate diagnoses in less time and increased productivity and confidence for radiologists. Hospitals and health care systems have increasingly recognized the advantages of these systems, with Sage Growth Partners reporting that 90% of hospitals have an AI strategy in place, up from 53% in 2019, but the deployment lags, with only 34% of hospitals having installed an AI solution.

LONDON – Brainomix Ltd. has raised £16 million (US$ 21.2 million) in a series B, enabling the company to extend its artificial intelligence (AI)-driven diagnostic platform beyond the initial deployment in stroke, to the assessment of disease progression in lung fibrosis, and response to therapy in lung cancer.
