Trimers of nanobodies, a simpler form of antibody made by some animal species, were effective at preventing and treating COVID-19 in preclinical studies, researchers reported in the Sept. 22, 2021, issue of Nature Communications. The findings, along with others, could form the basis of an inhaled biologics treatment for COVID-19 and, ultimately, other respiratory diseases.
The U.S. FDA has cleared Memed Diagnostics Ltd.'s blood test for distinguishing between bacterial and viral infections. The diagnostic test has been tipped as an essential step in the fight against antimicrobial resistance. While most infectious disease tests look for the pathogen, Memed BV is an advanced host immune response test that measures the levels of immune system proteins and applies proprietary algorithms to generate an immune signature.
A multicenter study has found that a multiplex diagnostic panel developed by Opgen Inc. can reduce the use of inappropriate antibiotic therapy by 45.1%. Opgen’s Unyvero Hospitalized Pneumonia (HPN) panel uses PCR technology that can detect 21 pathogens and 17 antibiotic resistance markers in less than five hours. During the European Respiratory Society conference, Rockville, Md.-based Opgen presented data showing that combined with antibiotic stewardship, its HPN panel decreased time on inappropriate antibiotic therapy in hospitalized patients with pneumonia at risk for Gram-negative rods.
The FDA’s pre-IND response to Virpax Pharmaceuticals Inc.’s MMS-019, a molecular masking spray being developed as an over-the-counter product to limit transmission of SARS and influenza, has the company breathing easier and ready to chase an NDA. Virpax is in a crowded field of 43 COVID-19 intranasal therapeutics and vaccine programs.
It's a good news, bad news scenario for exhausted T cells in chronic infections. Multiple groups of investigators reported in the July 26, 2021, online issue of NatureImmunology that even after a chronic hepatitis C virus infection was cured, T cells that had become dysfunctional during the infection retained epigenetic "scars" that prevented them from becoming fully functional memory T cells.
PARIS – At some point, scientists reported, it may be possible to quarantine viruses rather than humans. For the last two years, European research consortium Virofight has been working on a form of nanotechnology intended to neutralize viruses such as SARS-CoV-2, HIV, influenza and hepatitis viruses.
Nanodx Inc. entered into a license agreement with IBM Research to use IBM’s nanoscale sensor technology and develop diagnostic platforms for rapid and cost-effective detection of various diseases, including COVID-19 and traumatic brain injury, among others. This marks IBM’s first collaboration to allow a medical device company to use its nanoscale technology.
The World Health Organization (WHO) and the Global Fund to Fight AIDS, Tuberculosis and Malaria signed a cooperation and financing agreement to implement 10 initiatives in 2021 through 2023 aimed at addressing persistent challenges impeding global progress against the three diseases and protecting hard-won gains from new pandemics like COVID-19.
Mindup, an Israeli digital health incubator, added Phenofast Ltd. to its portfolio this week, banking on the startup’s ability to resolve a critical, ongoing problem for hospitals and community physicians treating patients with urinary tract infections (UTIs). Phenofast hopes to bring clarity to antimicrobial susceptibility testing (AST) and relief to patients in record time.
Startup Aplife Biotech is tapping into the rapidly growing market for biosensors that can expand the capacity of hand-held devices to screen for thousands of pathologies from a single drop of blood. Using technology developed in Argentina to print DNA structures on microchips, the company’s goal is to screen as many as 20 million probes with the potential to convert molecular interactions into electrical signals, opening a path for med-tech developers and manufacturers to explore new solutions for personalized health care.
