Exo Imaging Inc. closed a $40 million series B+ funding round that is earmarked to help with the development of a hand-held ultrasound device and cloud-based workflow software platform. The funding follows a series B round in August 2019 that reeled in $35 million and brings the company’s total raise to nearly $100 million.

The U.S. Department of Health and Human Services (HHS) has ordered the FDA to cease requiring developers of lab-developed tests (LDTs) to go through the agency’s premarket review mechanisms before offering an LDT. The context of the order might at first blush be interpreted as limiting the scope of the order to the public health emergency (PHE) to the COVID-19 pandemic, but the statement expands the temporal scope by referencing a need for rulemaking on the FDA’s part, one of several indications that this order is intended to outlast the PHE.

LONDON – European scale-up of an artificial intelligence tool for stratifying and personalizing treatment of COVID-19 patients according to the type of complications they are likely to experience will get underway in September, following initial validation. The tool, developed by researchers at the Hospital Clinic Barcelona, Spain, was ‘trained’ on more than a trillion anonymized data points retrieved from the clinic’s electronic health records system.

The U.S. FDA has granted emergency use authorization (EUA) to Lumiradx UK Ltd. for its point-of-care SARS-CoV-2 antigen test, which aims to speed the diagnosis of people suspected of having the virus that causes COVID-19. The test detects antigen nucleocapsid protein from a nasal swab taken from symptomatic patients and delivers results in less than 12 minutes.

Avoiding the political overtones that seem to be more viral than COVID-19 these days, Anand Shah, deputy commissioner for medical and scientific affairs at the FDA, stressed that even though the agency is making decisions in real time in response to the urgency of the pandemic in the U.S., its decisions are being driven by scientific integrity, regulatory independence and the FDA’s historic commitment to ensuring the safety and efficacy of the products it regulates.

Thermo Fisher Scientific Inc. released updated software and new instructions for its Taqpath COVID-19 Combo Kit, a widely used COVID-19 test kit that is also the basis for several other coronavirus diagnostics, following issuance of a letter to clinical laboratory staff and health care providers by the U.S. FDA about the risk of false results with the test. Separately, the Waltham, Mass.-based company has released the first in a series of hematology-oncology assays designed to run on its Ion Torrent Genexus system.

With an eye toward launching its first product, Mobilion Systems Inc. has revealed a $35 million series B funding round led by Amoon. Todd Sone, partner at Amoon who also is joining the company’s board, highlighted the duo’s common vision to develop technologies that offer high resolution and speed.

The COVID-19 pandemic has spurred a considerable amount of testing innovation, including more extensive use of saliva as a medium for detection of pathogens. The U.S. FDA has announced an emergency use authorization (EUA) to Yale School of Public Health for the Salivadirect testing protocol that requires no extraction of the SARS-CoV-2 virus’s RNA, a feature that Assistant Secretary for Health Brett Giroir said is “yet another testing innovation game changer that will reduce demand for scarce testing resources.”

LONDON – A large scale population study has shown that home self-testing with low-cost lateral flow diagnostics is a valid way of tracking the COVID-19 pandemic. A total of 105,651 people across the U.K. tested themselves for SARS-CoV-2 antibodies with a fingerprick blood test as part of the REACT (REaltime Assessment of Community Transmission) study.
