On March 4, 2024, several groups of scientists discussed the challenges of investigating the effects of HIV in the central nervous system (CNS) at the oral abstract session on neuropathogenesis of HIV held during the 31st Conference on Retroviruses and Opportunistic Infections (CROI), in Denver. A cure for HIV will require eliminating the virus in all its reservoirs, those tissues where HIV remains latent but retains the capacity for reactivation and replication. However, despite antiretroviral therapy (ART), the virus could continue to replicate continuously at a low level in some reservoirs, including the CNS.
In 2023, the BioWorld Infectious Disease Index (BIDI) concluded with a 43.48% decline, showing improvement from the 83.57% drop observed in 2022. While an uptick was seen from October's year-to-date performance, down 47.98%, BIDI still lagged both the Nasdaq Biotechnology Index and the Dow Jones Industrial Average for the year, which saw gains of 3.74% and 13.7%, respectively.
In a move to widen global access to its Qdenga dengue vaccine, Takeda Pharmaceutical Co. Ltd. is partnering with India’s Biological E. Ltd. to manufacture Qdenga (TAK-003).
Allecra Therapeutics GmbH secured U.S. FDA approval for its beta-lactam/beta-lactamase inhibitor combination, Exblifep (cefepime/enmetazobactam), in complicated urinary tract infections, including pyelonephritis, in patients 18 years and older.
Baseimmune Ltd. has raised $11.3 million through a series A to accelerate the development of its deep learning AI technology for predicting future pathogen mutations to generate a series of longer-lasting, multistrain vaccines.
With a regulatory filing expected later this year for gepotidacin based on positive data in uncomplicated urinary tract infections, GSK plc reported that the potentially first-in-class oral antibiotic hit its endpoints in a phase III trial in uncomplicated urogenital gonorrhea, the sexually transmitted disease facing a rise in incidence rate and increased antibiotic resistance.
SK Bioscience Co. Ltd. of Seongnam-si, South Korea, gained the World Health Organization’s (WHO) prequalification certification for typhoid conjugate vaccine, Skytyphoid (NBP-618), on Feb. 23. Skytyphoid conjugates a polysaccharide of typhoid bacteria, which serves as an antigen, to a diphtheria toxin protein called diphtheria toxoid that acts as a carrier.
The good news is that the U.S. FDA’s complete response letter (CRL) for Venatorx Pharmaceuticals Inc.’s intravenous antibiotic combination, cefepime-taniborbactam, in complicated urinary tract infections (cUTIs) requested no additional clinical testing. The bad news is the inevitable delay for a drug Venatorx and partner Melinta Therapeutics Inc. are aiming to position as a much-needed option for the fight against drug-resistant gram-negative infections.
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.
