The biological processes giving rise to the central nervous system symptoms of long COVID remain a mystery. But multiple studies suggest they do not appear to be a result of a direct viral infection of brain tissue. The latest such research, which appeared online in Nature Neuroscience on Feb. 16, 2024, demonstrated that local immune response in brain tissues persisted long after SARS-CoV-2 virus had disappeared.
AN2 Therapeutics Inc.’s decision to pause enrollment in the phase III portion of its phase II/III testing epetraborole in treatment-refractory Mycobacterium avium complex lung disease, citing potentially lower-than-expected efficacy from a blinded aggregate analysis of the phase II portion, left analysts and investors with little to do but speculate on the program’s viability going forward.
The U.S. Department of Health and Human Services (HHS) has released a sweeping plan that is designed to help manage vector-borne pathogens, such as the Zika virus, with the ultimate goal of reducing the related disease burden to zero.
The topical combination therapy miconazole plus domiphen bromide (MCZ-DB) resolved signs and symptoms of acute vulvovaginal candidiasis (VVC) and eradicated the yeast Candida albicans from vaginal swabs to a greater extent than miconazole (MCZ) alone in a phase II study, according to Hyloris Pharmaceuticals SA and Purna Female Healthcare.
Be it viral, nucleic acid or protein vaccines, recent efforts that led to the first regulatory approvals for not only COVID-19, but also for malaria and respiratory syncytial virus, positioned infectious diseases in the headlines for much of the last four years. But despite that attention, or the threat of future pandemics, or the numerous infectious diseases for which there are no preventable vaccines and very little development activity, the level of private and public funding for biopharma companies working in the space is dismal – at least compared with that of oncology products, according to a new analysis report released by the Biotechnology Innovation Organization (BIO) on Jan. 25.
Researchers at ETH Zurich have identified a proteomic signature that could recognize long COVID six months after acute infection. Biologically, the signature indicated that the complement system remained active in patients with long COVID six months after infection. Translationally, it could lead to a diagnostic test for long COVID, and suggests that targeting the complement system could be a therapeutic approach to prevent or treat the disorder.
Acurx Pharmaceuticals Inc. continues to post positive data for its lead candidate ibezapolstat but that didn’t stop the stock from tumbling. The antibiotic outperformed vancomycin in a phase IIb study treating Clostridioides difficile infection (CDI). Vancomycin is a standard of care in the indication. Ibezapolstat eradicated fecal CDI at day 3 in 15 of 16 patients compared to vancomycin, which eradicated fecal CDI in 10 of 14 patients.
Merck & Co. Inc. CEO Robert Davis said the pneumococcal vaccines (PCVs) space is “an area where there is still a high unmet need, and what we have is a new vaccine specifically targeted to the adult population that addresses 83% of the residual disease. That's about 30% higher than anyone else that's out there.” Speaking Jan. 9 at the J.P. Morgan Healthcare Conference (JPM), Davis predicted that his firm “will take a majority share” of the market if approved. The Merck candidate, V-116, bears a PDUFA date with the U.S. FDA of June 17.
Researchers have identified a new class of antibiotics that works by blocking the transportation of lipopolysaccharide (LPS) to the outer membrane of the gram-negative bacterium Acinetobacter baumannii. The most advanced member of the class, zosurabalpin (RG-6006, Roche AG), was effective against multiple A. baumannii strains, including carbapenem-resistant and multidrug-resistant strains.
It is not the first malaria vaccine, but R21, recommended for use by the World Health Organization in October, is the first that can be manufactured at modest cost and the sort of scale needed for widespread prevention of the killer disease in Africa.
