PARIS – A consortium led by French clinical and scientific experts has just published results in the Journal of Experimental Medicine of a study showing the contribution of a new simplified diagnostic test in better identifying the level of contagiousness of subjects infected with SARS-CoV-2.

The U.S. Federal Trade Commission (FTC) is hardly alone in its antipathy toward Illumina Inc.'s acquisition of Grail Inc., and FTC attorney Susan Musser said Aug. 24 that Illumina’s dominance of the market for next-generation sequencing (NGS) is perhaps the key aspect of the FTC’s case. Musser invoked the wide number of companies that jumped into the fray to develop a vaccine for the COVID-19 pandemic as an illustration of the need to maintain competition in the multicancer testing space.

Fujifilm Holdings Corp. has bagged the Japanese Pharmaceuticals and Medical Devices Agency (PMDA)’s approval for CXR-AID, its artificial intelligence (AI) powered chest X-ray analysis system developed in collaboration with Lunit Inc.

Illumina Inc.’s acquisition of cancer diagnostic specialist Grail Inc. is on go in a $7.1 billion transaction that is structured so that it can be unwound with limited impact on Illumina. However, a number of regulatory entities are closely scrutinizing the deal for a potential regulatory challenge, a fact of life that shaved nearly 10% off the value of the company’s shares in early Aug. 19 trading, and which could ultimately scuttle the transaction altogether.

The FDA’s emergency use authorization (EUA) program is still active in the area of tests and test kits, which is due in part by the emergence of the Delta variant of the SARS-CoV-2 virus and the associated warnings that the effectiveness of vaccines may be declining. One example of the sustained emphasis on testing is the EUA granted to Thermo Fisher Scientific Inc. for two PCR test kits that can detect the latest variants of the virus, a demonstration that the demand for these updated tests seems unlikely to ebb anytime soon.

Scientists at Cleveland-based Case Western Reserve University have used artificial intelligence (AI) to identify biomarkers contained in naturally occurring collagen that could predict whether breast cancer will return after treatment. Identified from standard tissue biopsy slides of early-stage breast cancer, collagen-based assays could also be less expensive than gene expression-based assays typically conducted at highly specialized labs in California.

LONDON – Researchers at Birmingham University are looking for commercialization partners after finding a happy medium between the speed but limited accuracy of COVID-19 lateral flow antigen tests, and the use of slower but more accurate PCR and other RNA amplification diagnostics.

PERTH, Australia – Australia’s Therapeutic Goods Administration (TGA) has cleared Speedx Pty Ltd.’s PlexPCR SARS-CoV-2 test, which detects all current circulating variants of the SARS-CoV-2 virus at a time when most of the country is in lockdown as the delta variant circulates.
