Having caused over 6.2 million deaths globally ongoing, the COVID-19 pandemic since 2020 continues to pose a serious public health challenge. While the SARS-CoV-2 receptors angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 play requisite roles in permitting the initial infection, up to 10 proviral host factors have also been determined to play crucial roles in controlling the viral replication, but most are not pharmacologically targetable.
The U.S. FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously to recommend COVID-19 vaccines for the 2023-2024 vaccination campaign be monovalent vaccines that target the XBB variants, currently the most prominent variants of the SARS-CoV-2 virus.
U.S. federal authorities continue to wrap up cases in connection with COVID fraud, the latest of which yielded a $30 million fine for a single defendant accused of fraud and money laundering.
Asep Medical Holdings Inc. reported “ground-breaking” use of artificial intelligence in its SepsetER test to rapidly identify infections at increased risk of severe sepsis. Developed under guidance by Professor Robert E.W. Hancock at the University of British Columbia, analysis of dysfunctional immune responses to identify particular sets of genes could signal when a patient is at risk of acquiring and potentially dying from severe sepsis.
The U.S.FDA posted two warning letters to medical device manufacturers June 6, one each to Irhythm Technologies Inc., and Steiner Biotechnology LLC, and both warnings include citations for marketing for claims that are not in the FDA-reviewed product labels.
Scientists from the Hospital for Sick Children Research Institute and collaborators have reported the application of a multispecific, multiaffinity antibody (Multabody, MB) platform derived from the human apoferritin protomer to enable the multimerization of antibody fragments against SARS-CoV-2. These MBs showed high potency to neutralize SARS-CoV-2 even at lower concentrations than their corresponding MAb counterparts.
The intellectual property waivers for American vaccines for the COVID-19 pandemic are still controversial, but the World Health Organization (WHO) is nonetheless seeking a similar set of waivers for therapies and tests for COVID. A subcommittee of the House Judiciary Committee met June 6 to review these waivers, and subcommittee chairman Darrell Issa (R-Calif.) said he intends to continue pushing legislation that would require the U.S. president to obtain congressional approval for agreeing to any such waivers in the future.
The EMA and the European Center for Disease Control have said COVID-19 vaccine manufacturers should ditch the existing formulations and adapt their products to target the omicron-descendant XBB.1.5, to protect against SARS-CoV-2 in the winter of 2023–2024.
Suzhou Spring-Sea Bio-Pharmaceuticals Co. Ltd. has prepared and tested prodrugs of N4-hydroxycytidine (NHC) that are reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
