LONDON – Liquid biopsy specialist Inivata Ltd. has been granted a U.S. FDA breakthrough device designation for its Radar assay for detecting residual disease or relapse, following treatment for cancer. The personalized assay, which tracks a set of up to 48 genetic variants isolated from excised tumor tissue, is built on Inivata’s approved Invision platform for detecting circulating tumor DNA (ctDNA) in blood samples.

Mahana Therapeutics Inc. obtained a CE mark for Parallel, a prescription digital therapeutic device to treat irritable bowel syndrome (IBS) in conjunction with other IBS treatments. Developed by a team of U.K. psychologists, the three-month program delivers cognitive behavioral therapy (CBT) via a web-based application.

MIT Media Labs spinoff Empatica Inc. secured the CE mark for its Aura system, a wearable solution for the monitoring and early alert of respiratory infections, including COVID-19. For use with people 14 and older, Aura is commercially available in Europe and the U.K., and for pilot purposes in the U.S. – pending FDA authorization. Aura’s algorithm analyzes vital signs from Empatica smartwatches, comparing data against the wearer’s historical baselines. In validation studies, Aura was able to detect patients with possible H1N1 influenza, rhinovirus or SARS-CoV-2 infection with 0.94 sensitivity. Detection occurred on average two days after infection.

In a span of a mere two years, the state of California passed two ballot initiatives dealing with privacy that promise to have an impact on digital health, the second of which created an office specifically for privacy enforcement matters. Eric Goldman, a professor of law at the Santa Clara (California) University School of Law, said on a recent webinar that the state attorney general’s office and the new California Privacy Protection Agency (CPPA) have overlapping jurisdiction, and as a consequence, companies doing business in California may find themselves at the mercy of not one, but two enforcement entities.

Cue Health Inc. became the first company to offer COVID-19 molecular testing for home use without a prescription following U.S. FDA emergency use authorization on March 5, 2021. The San Diego-based company’s isothermal nucleic acid amplification test (NAAT) detects RNA from SARS-CoV-2 virus present in the nostrils. “The FDA continues to prioritize the availability of more at-home testing options in response to the pandemic,” said Jeff Shuren, director of the FDA’s Center for Devices and Radiological Health. “Cue COVID-19 Test for Home and Over-the-Counter (OTC) Use provides access to accurate and reliable testing at-home, without a prescription.”
