The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria. If approved, Emblaveo would be among the first beta-lactam/beta-lactamase inhibitor combos cleared for use in Europe.

One topic at the 31st Conference on Retroviruses and Opportunistic Infections (CROI 2024) held in Denver this month was that resistance to antiretroviral therapy (ART) has become a public health problem for people living with HIV. Without a vaccine or a cure, these patients depend on treatments that suppress viremia by preventing the virus from replicating. They are lifelong treatments and, until new advances succeed in eradicating the virus from reservoirs, the only option available.

Overall, the story of HIV is one of astounding success. But to declare victory, it will be necessary to develop a vaccine. The opening session of the 31st Conference on Retroviruses and Opportunistic Infections (CROI) 2024 looked back to the failures but also the advances in research, all the steps that over the years brought the basic science knowledge that could bring an HIV vaccine in the future. This year, the former director of the Viral Pathogenesis Laboratory at the NIAID Vaccine Research Center, Barney Graham, was named for the Bernard Field Lecture, where he presented “Modern vaccinology: a legacy of HIV research.”

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.

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.
