Pfizer Inc.’s Paxlovid has become such a part of the COVID-19 treatment scene in the U.S. that it’s easy to forget it’s only authorized for emergency use. That could soon change. The FDA is convening its Antimicrobial Drugs Advisory Committee March 16 to consider Pfizer’s NDA for the co-packaged nirmatrelvir and ritonavir treatment.
Pardes Biosciences Inc. has patented 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of viral infections.
Exevir Bio BV has announced research detailing a novel, highly potent, anti-S2 camelid single-domain antibody, discovered at the VIB-Ugent Center for Medical Biotechnology, and developed as a candidate drug molecule by Exevir as XVR-013.
Researchers from Case Western Reserve University presented data from a study that aimed to investigate gut integrity, oxidized lipids and inflammatory markers associated with the pathogenesis of post-acute sequelae of COVID-19 (PASC).
The FDA’s emergency use authorization (EUA) program for rapid antigen tests for the COVID-19 pandemic is coming to an end, but few rapid antigen test makers have laid out clear plans regarding the post-public health emergency world. Quidelortho Corp. managed to beat the competition to the non-EUA market for these tests with a grant of de novo petition for its Sofia rapid antigen test, which now provides other tests with a predicate device, thus ensuring that this will not be the last such test to reach the U.S. market.
Immorna Biotechnology Co. Ltd. raised nearly $100 million in series A+ and A++ financing rounds to speed up the clinical development and commercialization of its RNA-based therapeutics. Founded in 2019, Immorna develops therapeutics and vaccines based on its RNA platforms, including conventional, self-replicating and circular RNA.
Autoantibodies are typically not good news. But a group of researchers from Bellinzona, Switzerland, have observed that the presence of autoantibodies against chemokines, a special class of cytokines, is associated with mild disease and less risk of developing long COVID. “Our hypothesis was that antibodies to chemokines, if they existed, would also be associated with a negative outcome of the disease. But, what we found, in fact, was the exact opposite of what we were predicting,” Davide Robbiani, director of the Institute for Research in Biomedicine, told BioWorld.
Shares of Veru Inc. hit a 52-week low March 3 after the U.S. FDA declined to grant an emergency use authorization (EUA) for sabizabulin for use in hospitalized adults with moderate to severe COVID-19 who are at high risk for acute respiratory distress syndrome. The decision comes as little surprise, given the negative advisory panel vote in November, but the agency’s wording might suggest potential use for the microtubule disruptor in the future.
