A survey of members demonstrated positive findings, including many industry members having implemented measures to support antimicrobial stewardship and efforts to increase antibiotic access in lower-resource countries, as well as having invested in AMR-relevant R&D. On the other hand, there has been a decline in AMR researchers over the last few decades, leading to less published research on AMR and fewer patents on new antibiotics, the decline particularly acute when compared to cancer and HIV/AIDS. The findings highlight the need for government and private sector incentives to provide adequate funding and investment for AMR research and novel antibiotic development, as well as for efforts to introduce young scientists to the field.The Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) recently announced $1.8 million in funding to biotechnology company Visby Medical to develop a portable rapid diagnostic test that detects Neisseria gonorrhoeae, the pathogen that causes gonorrhea, as well as its susceptibility to ciprofloxacin, an oral antibiotic that was formerly a go-to treatment, which can no longer treat resistant forms of the pathogen. The test would allow health care providers to rapidly test and refer patients to the right treatment while hopefully ensuring that ceftriaxone, the only remaining effective antibiotic against resistant N. gonorrhea, is properly managed. The funding will also support the development of a test for N. gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis in men based on urine samples.The Coalition for Epidemic Preparedness Innovations (CEPI) will provide up to $2 million in funding to German biotech company LenioBio GmbH for a preclinical proof-of-concept for using its commercially available, plant-based, and cell-free technology to produce proteins for use in clinical trials testing vaccines against epidemic and pandemic threats in 20 to 40 days. If proven successful, this approach could greatly reduce the time it traditionally takes to manufacture vaccine proteins using other methods, which would be a major boon to CEPI’s 100 Days Mission to develop vaccines against novel pathogens with pandemic potential within 100 days of identification. The easy-to-use technology could also be rolled out for use in remote or low-resource settings, allowing greater availability of and access to future vaccines in those settings.

The agreement was negotiated under the COVID-19 Technology Access Pool (C-TAP), which was launched at the beginning of the COVID-19 pandemic, but it includes a broad range of diseases, including HIV, malaria, and syphilis. The rapid testing technology is the basis of SD Biosensor’s COVID-19 antigen test and is ideal for low- and middle-income countries because it has no equipment requirements and is easy to use with high sensitivity. The announcement also coincided with the unveiling of a new business model, the Health Technology Access Pool, which will succeed C-TAP and address other priority health issues beyond COVID-19.A new project—FLAVIVACCINE—from a diverse consortium of partners aims to increase the European Union’s ability to combat epidemic and viral threats in Europe and globally by supporting the development of a pan-flavivirus vaccine candidate that could protect against multiple flaviviruses, such as dengue, yellow fever, Zika, and West Nile. Beyond seeking a vaccine candidate, the project also aims to provide support across the R&D value chain, offering a boost to the broader global pandemic preparedness and response capability. The project is being organized by public and private institutions, including universities, research institutions, and a vaccine developer, spanning seven countries in Europe and the United States.A new grant to the Drugs for Neglected Diseases initiative (DNDi) from the Bill & Melinda Gates Foundation will support the development of innovative new drugs for sleeping sickness and river blindness. Specifically, the $20 million grant spanning until 2027 will support a single-dose cure for sleeping sickness and a short-course new treatment for river blindness, both diseases with a major footprint in sub-Saharan Africa and for which new tools are urgently needed to accelerate progress toward elimination, despite enormous progress in controlling them in recent years. These investments build on earlier-stage research also supported by the Gates Foundation.

During the COVID-19 pandemic, there was huge global investment in genomic surveillance infrastructure, with the Stellenbosch lab being the first to confirm the discovery of the Beta and Omicron variants. In the last year alone, the work of the two labs has contributed to doubling the number of sequences available for dengue, chikungunya, and malaria parasites. Genomic surveillance uses sequencing to get data about the genetic material of a pathogen, which is then used to track how the pathogen is changing or spreading.Researchers from the Health and Medical Research Institute at Japan’s National Institute of Advanced Industrial Science and Technology have developed a bioluminescent assay that could serve as a rapid, low-cost, and convenient test to complement laboratory testing for COVID-19. The test uses a bioluminescent molecule found in some small crustaceans that glows when it reacts with the virus that causes COVID-19 in a saliva sample and can be used with commercially available handheld luminometers at the point-of-care. The research team is planning for initial commercialization in the Japanese and US markets.ProteinLogic and Stellenbosch University will use a $1.35 million grant from the Bill & Melinda Gates Foundation to determine whether an immunoassay technology being developed by ProteinLogic can be used to monitor treatment response to tuberculosis (TB) antimicrobial chemotherapy in patients. ProteinLogic's ImmiPrint testing technology is a protein-based test based on predictive models developed through machine learning that aims to offer rapid, efficient, and cost-effective discovery of diagnostic biomarkers across multiple diseases. Its new partner, Stellenbosch University, has been leading clinical trials on TB diagnostic biomarkers. In the face of the growing threat of drug-resistant strains of Mycobacterium tuberculosis, there is an urgent need for new technologies to monitor the effectiveness of current treatments, in addition to the need for novel treatments and prevention methods for TB.

Neglected tropical diseases (NTDs) are a group of infectious diseases that exert a crushing burden in vulnerable communities around the world. These diseases can blind, disable, and disfigure people, robbing them of health and opportunity and trapping them in poverty. While breakthroughs in recent years have brought new resources to the fight against NTDs, significant gaps remain in the arsenal of tools needed to control and eliminate these diseases. In recognition of World NTD Day on January 30, GHTC is testing our readers’ knowledge with nine questions about NTD innovation. See if you can beat our quiz below, and join the fight to #BeatNTDs and #EndTheNeglect.

The antibodies, one isolated from a person living with HIV and the other two from rhesus macaques, all target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells, with the results validating the fusion peptide as a potential target for a human vaccine. Hopefully, the approach will continue to show promise in future studies, although a vaccine for humans would need to be able to generate multiple varieties of antibodies directed at the fusion peptide to increase the likelihood that the vaccine could prevent the full diversity of HIV variants.A study published last week found that simnotrelvir, a COVID-19 drug administered as a series of pills, was effective in speeding recovery from mild to moderate disease. The drug was tested primarily in young people with standard levels of risk, a change from earlier antiviral drug trials during the pandemic, which included mostly people at high risk of severe COVID-19. The researchers combined simnotrelvir with a component of Paxlovid, currently the most widely used COVID-19 pill, with strong results and the only downsides similar to those of Paxlovid: bad taste and incompatibility with some common medications. Simnotrelvir has been available in China under an emergency use authorization since early last year and has been incredibly popular due, in part, to its much lower price tag compared to Paxlovid.Last week, the Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) announced that it is awarding $633,000 to Intravacc to develop a vaccine for gonorrhea, which is the world’s second most reported sexually transmitted infection. The new vaccine could be a game changer in curbing new cases of gonorrhea, as well as addressing the rising spread of resistance of Neisseria gonorrhoeae to the only antibiotic still effective in treating it. The funding will support the early-stage development of Intravacc’s meningococcal outer membrane vesical vaccine, which includes antigens designed to protect against infections caused by N. gonorrhoeae.

Despite the need for new tools to address the remaining burden of the disease, there are disappointingly few in the pipeline. There is one drug, linezolid, being evaluated that, like azithromycin, is easy to transport and administer, as well as an updated mass community treatment approach with azithromycin. Although the bacteria that causes yaws is tricky to target with a vaccine, ongoing research on a syphilis vaccine that targets the same bacteria that causes yaws could offer cross-protection. With underreported cases also a barrier to eradication, new, robust tests are also a major gap in the tools in our arsenal. The first human trial of a new vaccine against the deadly Nipah virus began last week after the work, which started in 2017, was paused during the COVID-19 pandemic. South Asia faces the greatest burden of Nipah virus, the priority pandemic pathogen that can be fatal in up to 75 percent of cases. There are currently no treatments or vaccines available against Nipah. The new vaccine, ChAdOx1 NipahB, which was developed using the same viral vector vaccine technology as the University of Oxford and AstraZeneca’s COVID-19 vaccine, will be evaluated over the next 18 months in a trial led by the Oxford Vaccine Group and funded by the Coalition for Epidemic Preparedness Innovations (CEPI). The World Health Organization (WHO) recently prequalified the novel oral poliovirus vaccine type 2 (nOPV2), the first prequalification of a vaccine being used under WHO's emergency use listing. nOPV2 was developed by an international consortium, which included GHTC members: Bill & Melinda Gates Foundation and PATH, and is as safe and effective as its predecessor, the oral polio vaccine, but more genetically stable, meaning it is much less likely to lead to vaccine-derived outbreaks. Nearly 1 billion doses of the vaccine have been administered across 35 countries since the rollout began in March 2021, and it has already played a key role in addressing outbreaks of type 2 variant poliovirus. WHO's decision now paves the way for even more countries to receive the vaccine.The Novo Nordisk Foundation, the nonprofit holding of Novo Nordisk and Novozymes, has announced a new grant of $25 million to the Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X). With this grant, the Novo Nordisk Foundation joins major governments and foundations in supporting the work of CARB-X to accelerate the early-stage development of innovative tools to prevent, diagnose, and treat drug-resistant bacterial infections. Efforts are focused on the most dangerous bacteria, which have been prioritized by the World Health Organization and the US Centers for Disease Control and Prevention, the syndromes with the greatest morbidity and mortality across the world, and the performance characteristics that clinicians and patients need the most. Since 2016, CARB-X has funded 93 projects in 12 countries, with 19 projects having advanced into or completed clinical trials; 12 actively in clinical development, including late-stage clinical trials; and two diagnostic products on the market.
