CRISPR, or clustered regularly interspaced palindromic repeats, is transforming biomedical research, and making rapid inroads into the clinic, with its ability to easily target specific DNA and RNA sequences. CRISPR itself is made of RNA. It recognizes target sequences and delivers CRISPR-associated (Cas) proteins, nucleases that cut the target sequence. In two papers published online in Nature on Jan. 4, 2023, researchers have demonstrated that a recently discovered type of Cas protein, Cas12a2, can degrade double-stranded DNA when its associated CRISPR guide RNA recognizes its target sequence.
The U.S. FDA has approved Polarean Imaging plc’s drug-device combination product, Xenoview, for use with magnetic resonance imaging (MRI) in evaluating lung ventilation in adults and children aged 12 and older. The hyperpolarized contrast agent, which is prepared from the Xenon Xe 129 gas blend, is expected to be commercially available in the U.S. starting next month.
Numares Health AG received $21.2 million from the European Investment Bank (EIB) in support to its automated and software based IVD platform for obtaining high-quality nuclear magnetic resonance metabolomics data from blood or urine biopsy samples.
Seekin Inc.’s cancer mutation detection kit Pancanseek for leukemia patients has received a CE-IVD mark, expanding the company’s reach in the testing space.
A new acute coronary syndrome detection system developed by Neuome Peptides Pte. Ltd.’s aims to make tests for the frequently lethal condition faster, more precise and less invasive. Neuome’s Truheart is a point-of-care assay for cardiovascular disease that is used in the company’s established Instadetect assay development platform. The assay measures the biomarkers troponins I and T and myoglobin.
Earlysight SA is developing a novel ophthalmology device that can be used to diagnose certain degenerative eye disorders long before onset of first symptoms. Earlysight and researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) have reported positive results for their first clinical trial of Cellularis in the journal Ophthalmology Science.
U.S. federal authorities have made a lot of noise over inappropriate medical testing in the past two years, largely due to the COVID-19 pandemic, but Paul Garcia, a partner in the San Diego office of Hooper, Lundy & Bookman PC, says this trend will not ebb at all in the coming year. Garcia told BioWorld that the lookback period for Medicare testing claims runs several years and that not only will enforcement results continue to surface next year, but also that the associated civil monetary penalties could force a testing lab to shutter its operations permanently.
Fujifilm Corp. inked an agreement to purchase the global digital pathology business of Inspirata Inc., paving the way for expansion of its Synapse enterprise imaging offering. The transaction includes Inspirata’s Dynamyx software, which Fujifilm has distributed in the U.K. and certain European Union countries since mid-2020. Under the agreement, Fujifilm will acquire Inspirata’s digital pathology technology, as well as employees and customers associated with the brand. Financial terms of the deal were not disclosed. It is expected to close in early 2023.
Cofactor Genomics Inc. opened the non-small-cell lung cancer portion of its study of the Oncoprism test, which predicts response to immunotherapy. The Predicting Immunotherapy Efficacy from Analysis of Pre-treatment Tumor Biopsies (PREDAPT) trial will study the test’s predictive ability in 11 cancers in total.
Guardant Health Inc. reported positive results from the ECLIPSE trial demonstrating 83% sensitivity of its DNA blood test in detecting colorectal cancer (CRC) in average-risk adults. Specificity was 90% in people without advanced neoplasia, as well as in those who had a negative colonoscopy result.
