The initiative, funding for which will come from the Biomedical Advanced Research and Development Authority, seems to be replacing Project NextGen, which had previously funded research into potential COVID-19 vaccines and treatments. Some experts and officials have expressed surprise at the direction of the initiative and the size of the investment.Scientists have discovered that a device used to diagnose bacterial meningitis in blood can also measure it in cerebrospinal fluid, helping speed accurate diagnosis and treatment of the illness, which is the most dangerous form of meningitis and a significant global health threat. The device has demonstrated high sensitivity in multiple cohorts of patients and it’s also affordable and delivers results within a half hour after spinal tap. The test was developed at an impressive speed, now available to patients within just a year of its discovery.Newly shared results from a clinical trial from the National Cancer Institute seem to confirm that a single dose of the vaccine used to prevent human papillomavirus (HPV) virus infection is just as effective as two, a finding that could transform efforts to reach the millions of children globally who are not getting vaccinated according to recommendations. Expanding HPV vaccination will also help reduce the global burden of cervical cancer deaths and deaths from other HPV cancers. While two doses are currently recommended, reducing the required dosage could make dissemination much easier and cheaper for many countries.

These results follow those of the first PURPOSE trial published earlier this year, which found that the drug was 100 percent effective as a prevention option in a study of women and adolescent girls. Lenacapavir is already approved and available in several countries, including the United States, as an HIV treatment option. With additional approvals as an HIV prevention option, the shot could be a game-changer for many marginalized communities that face the highest risk of HIV infection.A recent study found that the investigational drug quabodepistat in combination with delamanid and bedaquiline demonstrated safety and efficacy as a treatment for pulmonary tuberculosis (TB). TB treatment has historically been months long and difficult to tolerate, leading to discontinued treatment courses that raise the risk of the emergence of drug resistance. This combination treatment could potentially help fill the gap for safer, shorter regimens that cause fewer side effects. Further large-scale and long-term trials will be needed to validate these findings before this treatment combination can be available to the communities that face the highest burden of TB.Last week, the US Department of Health and Human Services announced nearly $27 million to support the rapid development and scale-up of manufacturing capacity for diagnostic tests to address future biologic threats through the Biomedical Advanced Research and Development Authority consortium. The COVID-19 pandemic exposed the gap in the United States' capacity to quickly develop, validate, produce, and roll out diagnostic tests to curb the spread of an infectious disease outbreak. While the funding will specifically support the development of tests to detect Burkholderia pseudomallei, the bacterium that causes melioidosis, and Marburg virus, the aim is to advance diagnostics platforms that can be leveraged to quickly produce tests for other threats as they emerge.

The first study from Cornell University and US National Institutes of Health researchers, which specifically looked at immunocompromised patients, found that the virus developed a reduced sensitivity to the drugs, while the second study from University of Pittsburgh, Brigham and Women’s Hospital, Stanford University, and Harvard University researchers also found resistant mutations, with the effect more evident in the immunocompromised and those who had received nirmatrelvir. These results raise concerns as the threat of antimicrobial resistance globally grows.Researchers from the University of California, Riverside; the University of California, Irvine; and the Yale School of Medicine have designed a new synthetic compound, MED6-189, which is effective against drug-sensitive and drug-resistant Plasmodium falciparum malaria strains in vitro and in mice engineered to have human blood. MED6-189, inspired by a compound extracted from marine sponges, works by targeting and disrupting a specialized part of P. falciparum cells, as well as the pathways used to transport materials within the cells, thereby preventing the pathogen from developing resistance. The next steps include continued optimization of the MED6-189 and further confirmation of its mechanisms of action, but, if the compound continues to demonstrate success, this research could lead to the development of an important tool to address the rising challenge of antimalarial drug resistance.Last week, the US Department of Health and Human Services through the Advanced Research Projects Agency for Health announced funding for the Transforming Antibiotic R&D with Generative AI to stop Emerging Threats project that will use artificial intelligence (AI) to speed up the discovery and development of new classes of antibiotics to meet the urgent need for new drugs amid the growing threat of antibiotic resistance. While conventional antibiotic discovery methods require time-consuming manual screening and testing of potential molecular compounds, most of which do not advance into further development, this project will employ deep learning to develop new methods to identify biomolecules with potential and use generative AI to expand the number of potential antibiotic candidates.

These exciting results come from an extension study of the efficacy trials among cisgender women that analyzed the outcomes of more than 300 pregnancies and infants. There has been limited data on the safety of long-acting injectable cabotegravir during pregnancy, so hopefully, these findings can fill that knowledge gap and lead to greater access to this highly effective HIV prevention option for this population, who may experience biological changes and social dynamics that can increase their likelihood of acquiring HIV during and after pregnancy.Last week, the Administration for Strategic Preparedness and Response at the US Department of Health and Human Services announced $25 million in funding to Walgreens to support a decentralized clinical trial testing COVID-19 vaccines. The study specifically aims to identify vaccine correlates of protection, or measurable immunity markers that correlate with protection against disease, using licensed or authorized COVID-19 vaccines to help assess immunity duration and streamline future clinical trials. This decentralized approach, which will include about 20 Walgreens pharmacies in urban, suburban, and rural communities, allows for a more diverse pool of study participants by bringing the study closer to where participants live. The funding comes through Project NextGen, a US government-led program to accelerate the development of next-generation COVID-19 technologies, including vaccines.  New data shows that Merck & Co.’s monoclonal antibody is safe and effective at reducing the incidence of respiratory syncytial virus (RSV)-related infections in infants. The Phase 2b/3 trial tested clesrovimab, also known as MK-1654, in healthy pre-term and full-term infants, finding that the antibody reduced the incidence of RSV-related infections over 150 days when compared to a placebo and hit key safety measures. The company announced that detailed findings will soon be presented to the scientific community and filed with global regulators. Hopefully, the antibody will eventually serve as an additional tool in the growing toolkit of new vaccines and monoclonal antibodies to address the burden of RSV in infants and older adults.
