Biondvax Pharmaceuticals Ltd. has reported statistically significant efficacy results from an in vivo proof-of-concept study of its innovative inhaled nanosized antibody (NanoAb) COVID-19 therapy.
Investigators at the University of Bristol and Biognos AB have identified a structural feature that distinguished the deadly coronavirus strains from harmless, common cold-causing variants. The findings, which were published in the Nov. 23, 2022, issue of Science Advances, could form the basis of universal COVID antivirals, putting an end to the endless race to deal with new variants that has so far been a necessity.
The researchers showed that the same pocket, a binding site for linoleic acid (LA), was present in all variants of concern (VOCs) that have emerged since 2020. “Intriguingly, all SARS-CoV-2 VOCs stringently maintain this pocket, notably including Omicron, which accumulated a wide range of mutations in [the spike protein] elsewhere, suggesting that the pocket provides a selective advantage for the virus,” they wrote in their paper.
An in-depth investigation of the underlying causes of pulmonary symptoms that in some cases persist for months following recovery from the acute stage of COVID-19 has found a distinctive proinflammatory signature in the plasma and airways of affected patients.
The first home pregnancy test to analyze saliva rather than urine is due to be on the shelves in Europe at the start of 2023, following CE approval of Salistick, developed by saliva diagnostic specialist Salignostics Ltd.
Pfizer Inc. and Biontech SE have initiated a phase I study to evaluate the safety, tolerability and immunogenicity of BNT-162b4, a next-generation COVID-19 vaccine candidate that aims to enhance SARS-CoV-2 T-cell responses and potentially broaden protection against COVID-19.
An in-depth investigation of the underlying causes of pulmonary symptoms that in some cases persist for months following recovery from the acute stage of COVID-19 has found a distinctive proinflammatory signature in the plasma and airways of affected patients. The research could provide an explanation for the ongoing interstitial lung disease and fibrosis seen in patients who were hospitalized with severe COVID-19, and also point to neutrophils as a specific therapeutic target.
Britain’s National Institute for Health and Care Excellence (NICE), a key gatekeeper on the path to the U.K. market, is backing away from five COVID-19 treatments. No longer recommended in a draft guidance were Ronapreve (casirivimab + imdevimab) from Roche Holding AG, Xevudy (sotrovimab) from GSK plc, and Evusheld (tixagevimab + cilgavimab) from Astrazeneca plc. NICE also recommended discontinuing use of Lagevrio (molnupiravir) from Merck and Co. Inc. and Veklury (remdesivir) from Gilead Sciences Inc.
Novartis AG has described 3C-like proteinase (3CLpro) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
The soluble form of human angiotensin-converting enzyme 2 (hsACE2) could prevent SARS-CoV-2 from binding to the host cell receptors through competitive inhibition, which may avoid viral infection. However, the relatively short half-life of the recombinant hsACE2 limits its clinical application.
