The updated vaccine is expected to be available in the fall, pending approvals from US Food and Drug Administration (FDA) and other national regulators. Novavax, as well as Pfizer and partner BioNTech, are also advancing updated shots.The United Kingdom’s Fleming Fund last week announced that it will provide up to $267.5 million for strengthening antimicrobial resistance (AMR) surveillance capacity in low- and middle-income countries in Africa and Asia, where the threat and burden of AMR is the highest. Specifically, the funding will go to upgrading laboratories, introducing new genome sequencing technology, and supporting training sessions. This announcement, which came ahead of this past weekend’s G20 Health Minister’s Meeting, where AMR was an important topic, marks a significant investment in a data-driven approach to fighting the rising threat of AMR.A new antibiotic combination drug that could significantly improve the treatment of complicated urinary tract infections and potentially serious infectious caused by highly resistant bacteria is now on track to receive a final review by FDA. Cefepime-taniborbactam, developed by Venatorx Pharmaceuticals and the Global Antibiotic Research & Development Partnership (GARDP), could be approved as early as next February. If successful, the treatment would be the first new treatment in GARDP’s clinical development portfolio to gain regulatory approval and would be a boon to global equitable access to new antibiotic treatments due to GARDP’s exclusive rights to distribute and sub-distribute the treatment in 64 low- and middle-income countries.

LPC-233 was found to be effective in protecting mice from fatal doses of multidrug-resistant bacteria by disrupting the synthesis of the outer membrane of the bacteria. LPC-233, which is a synthetic compound of the LpxC inhibitor, was developed after the first human trial of LpxC inhibitors failed because of cardiovascular toxicity. Hopefully, future studies will confirm the new antibiotic as a potential tool to address drug-resistant superbugs.Last week, the Project to Accelerate New Treatments for Tuberculosis (PAN-TB) collaboration announced the start of a phase 2b/c clinical trial to evaluate novel treatment regimens for drug-sensitive tuberculosis (TB). The trial, which is sponsored by the Bill & Melinda Gates Foundation, will evaluate two novel drug regimens made up of different combinations of five antibacterial agents—including the TB Alliance-developed pretomanid and the Janssen-developed bedaquiline— and will take place in high-burden countries starting with South Africa. The results will hopefully lead to a new, shorter pan-TB treatment regimen for patients.The Coalition for Epidemic Preparedness Innovations (CEPI) and Gennova Biopharmaceuticals last week announced a new agreement to advance the development of Gennova’s self-amplifying mRNA platform to create vaccine candidates against unknown pathogenic threats with pandemic potential. The funding will support the optimization and production of the platform technology and then the production of a vaccine candidate for preclinical studies against a known virus, rabies, to assess the new technology. This will hopefully lead to the development of novel RNA vaccines, which could offer significant advantages over existing mRNA vaccine platform technologies.
