Moderna's bird flu vaccine candidate is in very early-stage testing and uses the same mRNA technology as its COVID-19 vaccine. The new funding could support a late-stage trial of the vaccine candidate as early as next year if early study results continue to be positive. The vaccine could also be quickly redirected to target another form of influenza if a different threat emerges.A research team has developed a test that will help measure the persistence of HIV in people affected by viral strains found predominantly in Africa, which are greatly understudied, helping to fill a major gap in HIV research. Most HIV studies have focused on the strains circulating in Western countries, predominantly by men who have sex with men affected by subtype B, with much fewer studies examining strains circulating in Africa, where women are disproportionately affected. The new laboratory test allows researchers to determine whether following antiretroviral treatment there is any intact viral DNA capable of producing new viruses if antiretroviral treatment is interrupted. The test is already being used to study long-term viral persistence in Uganda and could be a vital tool in the search for an HIV cure that could target and eliminate this intact DNA reservoir.Last week, the US National Institutes of Health (NIH) announced the launch of a Phase 1 trial testing a nasal vaccine against COVID-19, the first trial conducted by NIH’s National Institute for Allergy and Infectious Diseases as part of Project NextGen, a US government initiative designed to advance the development of next-generation COVID-19 vaccines. In preclinical nonhuman primate studies, the candidate, MPV/S-2P, elicited a strong systemic immune response, as well as mucosal immunity, which plays an important role in controlling respiratory virus replication. Next-generation vaccines, including nasal vaccines, are a key tool needed to reduce COVID-19 infections and transmission as new variants of the virus continue to emerge.

The test received prequalification designations for use on the Cobas 5800 system and for self-collected samples on the Cobas 5800, 6800, and 8800 instruments, already having received WHO prequalification for use on the Cobas 6800 and 8800 systems last year. Prequalification will expand the availability of the test in many low- and middle-income countries that rely on prequalification to make regulatory, purchasing, and implementation decisions. Additionally, the use of self-collection, which was also recently approved by the US Food and Drug Administration, is expected to increase access to HPV testing by increasing comfort and ease for users.  The Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) recently announced a $1 million award to Prompt Diagnostics to further the development of a portable, point-of-care platform to detect multiple pathogenic bacteria targets and their antibiotic susceptibility, an urgently needed technology to help address rising drug resistance globally. Rapid, sophisticated diagnostics can enable early detection of infections, more effective treatment management, and improved antimicrobial stewardship to help prevent the emergence and spread of drug resistance, particularly in low-resource settings where drug-resistant infections are particularly hard to treat and the burden of drug resistance is highest. Specifically, CARB-X hopes the platform will demonstrate feasibility for detecting gonorrhea infections in the face of disproportionately high rates of gonorrhea in low- and middle-income countries.New research shows that a novel genetic vector control technique is highly effective at reducing the population of Anopheles gambiae, the primary vector for malaria in Africa. The technology could eventually serve a crucial role in reducing malaria transmission, especially as conventional methods, including insecticide-based technologies and environmental controls, are becoming less effective due to insecticide resistance. The precision-guided sterile insect technique uses CRISPR, a gene-editing tool, to produce genetically modified highly sterile male mosquitoes that then mate with and sterilize female mosquitoes, leading to robust population suppression. Developers say that compared to other genetic modification technologies developed for this mosquito species, the new technique is safer, scalable, and confinable.

On June 10, Sarah Bachar joined GHTC as our new Senior Program Assistant and Lindsey Brown joined as our new Multilateral Policy & Advocate Associate. GHTC’s Deputy Director Marissa Chmiola and Communications Coordinator Hannah Sachs-Wetstone sat down with Sarah and Lindsey to find more about themselves and their interests.1. What first got you interested in the field of global health research and development (R&D), and what inspires you about this line of work?Sarah: I grew up living in the United States and spending my summers in rural Tanzania, which laid the foundation for my lifelong global perspective and sparked my initial desire to work overseas. I studied international development in college, and, as an adult, I have had the opportunity to volunteer in East Africa on several projects bringing basic human services to under-resourced communities. I see health as the most central basic need that must be addressed to improve lives, and it’s exciting to live during a time in which incredible strides in R&D are making it more possible than ever to bolster health outcomes around the world. I’m thrilled to be part of a team helping to champion those solutions on a global scale.Lindsey: My interest in health R&D was sparked at a young age watching my father’s experience with type 1 diabetes. I can recall the significant improvement in his health and quality of life with each updated iteration of his insulin pump and supplies, which allowed greater ease with his blood sugar management. Witnessing firsthand the transformative impact of advanced and accessible medical technology underscored for me the critical importance of R&D in saving lives and improving health outcomes. During my graduate program, I fell into the global health policy space and delved deeper into the pivotal role of multilateralism. I became impassioned about the pursuit of universal health coverage, especially for low- and-middle income countries. In recognizing the potential for R&D to bridge health disparities and enhance health outcomes worldwide, I am proud to advocate for greater R&D to achieve health equity for all. 2. What are you most excited to learn about global health R&D at GHTC?Sarah: In my professional career thus far, I have been in roles focused on US policy and advocacy for domestic-facing investments, so, broadly, I’m thrilled to be learning more about the mechanisms and impact of health R&D globally. I’m also looking forward to diving more deeply into the different areas of technical work being focused on by each of the leading organizations that make up GHTC’s diverse membership and how to effectively tailor R&D approaches to maximize their impact. Lindsey: I am interested in delving into the sustainability and equity of global health R&D. With the GHTC team and extensive membership, I look forward to gaining insights into cutting-edge advances that are shaping global health outcomes. I am particularly enthusiastic about exploring resilient approaches to R&D, such as fostering partnerships that ensure equitable access to health innovations and health care delivery. Additionally, I believe that targeted investment in our last-mile communities can not only save lives but also foster sustainable health improvement on a global scale. I am excited by GHTC’s dedication to advancing global health R&D, with the ultimate goal of ensuring that everyone, regardless of geography or circumstance, has access to essential, lifesaving medical technology.3.

The study, which included more than 5,300 cisgender women and adolescent girls, was stopped early by an independent committee because the results exceeded efficacy expectations, with no incidences of HIV infection among participants who received the drug compared to those who were not on any prevention regimen. Truvada is already in wide use for both HIV treatment and prevention, but the twice-a-year lenacapavir injection, which could be approved for HIV prevention regimens by the end of next year, offers an option that could be much easier to adhere to than the daily pill for many people, especially higher-risk individuals.In Paris last week, as part of the replenishment launch for Gavi, the Vaccine Alliance, the African Vaccine Manufacturing Accelerator was launched, a project Gavi will invest $1 billion into over the next decade to help increase Africa’s vaccine manufacturing base to accelerate the rollout of vaccines and improve pandemic preparedness on the continent. This project follows glaring inequities in access to COVID-19 technologies faced by African countries during the pandemic. Specifically, Gavi will provide financial incentives to African vaccine manufacturers once they hit supply and regulatory milestones, using market forces to drive down prices and encourage upstream investment. The project set the goal for Africa countries to produce 60 percent of the vaccines used by the continent by 2040, up from 2 percent currently. It will also explore issues including technology transfer and regulatory harmonization.Elion Therapeutics recently announced the close of an $81 million funding round to advance the development of its next-generation polyene antifungal candidate, SF001, designed to reduce toxicity and address critical challenges associated with currently available antifungal options. The news comes as growing resistance to existing antifungals and increasing fungal infection rates highlight the need for new and improved tools. The promising compound received Qualified Infectious Disease Product and Fast Track designations in 2023 from the US Food and Drug Administration for early antifungal therapy of presumed invasive fungal infection and treatment of invasive aspergillosis. The funding round includes investments from the public-private partnership AMR Action Fund, the fund’s first investment in an antifungal company.

According to the report, new products are not being developed at the pace and scale needed to ensure new antibiotics are delivered, given the time required for products to move through the pipeline and the likelihood of failure. Specifically, the report identified gaps in agents for children, agents with more convenient oral formulations, and agents that can address drug-resistant pathogens. The report also stressed that efforts to boost innovation must accompany parallel efforts to ensure equitable access to existing and new products, particularly in low- and middle-income countries, where access gaps can hasten the rise of drug resistance.  Last week, the Global Antibiotic Research & Development Partnership (GARDP) announced an agreement with Bugworks Research to support the further development of a new broad-spectrum antibiotic that targets some of the most difficult-to-treat bacterial pathogens, aiming to enable access simultaneously in Western countries and low- and middle-income countries with a high burden of antimicrobial resistance. GARDP will provide Bugworks up to $20 million in financial and technical support through the approval and commercialization of BWC0977, a compound that has demonstrated in-vitro activity against WHO critical priority pathogens, in return for the manufacturing and commercialization rights to it in 146 primarily low- and middle-income countries. Bugworks previously received more than $12 million from the Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator, or CARB-X, for the preclinical development and Phase 1 study of the compound. Moderna recently announced positive late-stage trial results for mRNA-1083, its COVID-flu combination vaccine. The company is the first of several testing a combined COVID-flu vaccine to announce positive late-stage trial results, as experts raise calls for new tools to ensure more people have better protection against both viruses. Trial participants who received the vaccine showed an improved immune response compared with those who got the standalone flu and COVID vaccines that are currently available, even for people 65 years and older, who generally do not mount as robust immune responses to vaccines compared to younger people. The company hopes to have the vaccine approved for the fall of 2025.

There was some debate among experts on whether the vaccine should target the KP.2 subtype of the variant that is now most common in the United States or other offshoot subtypes that may become more dominant over the summer, ultimately deciding to target JN.1 itself, with the hope that the vaccine would offer some cross-protection against other subvariants that might emerge. Moderna, Pfizer, and Novavax say they could have JN.1.-specific shots ready by the fall.Two clinical trials have been launched to test a new, long-acting form of HIV pre-exposure prophylaxis, or PrEP, in cisgender women and people who inject drugs, two populations that have been largely underrepresented in HIV clinical trials. The mid-stage studies, sponsored and funded by Gilead and implemented through the HIV Prevention Trials Network, will test lenacapavir, an injectable antiretroviral drug administered every six months, which is already approved by the US Food and Drug Administration for HIV treatment in combination with other antiretroviral therapy for heavily treatment-experienced individuals and is the first in the capsid inhibitors class of drugs to be FDA approved for HIV treatment. The researchers hope these studies will provide critical data on the use of lenacapavir as HIV PrEP.Last week, the Sabin Vaccine Institute announced a new research project with the Kenya Medical Research Institute aimed at optimizing the use of the oral cholera vaccine in the face of a global resurgence in cholera and acute vaccine shortages, hopefully improving the impact of the vaccine and saving lives. The shortage of the oral cholera vaccine in 2022 led the World Health Organization (WHO) to temporarily modify the two-dose vaccine regimen and recommend a single dose during outbreaks, underscoring the urgent need for research to optimize vaccine use. WHO currently recommends two doses of oral cholera vaccine two weeks apart. The new research will test strategies to extend the time between doses to ensure that more people can receive protection.
