The prequalification of the assay, manufactured by OraSure Technologies, extends the 2017 prequalification of the company’s HCV test for professional use. Self-testing is recommended to complement existing testing services based on evidence demonstrating that it increases access to and uptake of services. The prequalification status will hopefully enable procurement in low- and middle-income countries, expanding access to HCV testing and treatment services and helping to contribute to the global goal of HCV elimination.The Safety of Antimalarials in First Trimester consortium, made up of scientific and social research experts on malaria in pregnancy has kicked off preparation for the first-ever Phase 3b clinical trial testing the efficacy and safety of antimalarials in women in their first trimester of pregnancy, which will be cosponsored by Medicines for Malaria Venture and the Liverpool School of Tropical Medicine. Pregnant women are typically excluded from clinical trials out of fear of causing harm, leaving few medicines for malaria treatment and no medicines for prevention available for women in their first trimester despite the significant health risks associated with malaria in pregnancy. The data from this trial could enable pregnant women and all women of childbearing age to safely take these antimalarial medicines without risk of causing harm, as well as support the design of future trials targeting other infectious diseases affecting pregnant women in low- and middle-income countries.  New research has led to the discovery of a potent adjuvant, PVP-037, that could induce a greater, more durable, and broader immune response to vaccines. Adjuvants are compounds that enhance the immune response, which are key to vaccine development, particularly for inactivated virus vaccines. Researchers identified the compound by screening a library of more than 200,000 small molecules found in human immune cells. In mice, an optimized form of the adjuvant boosted antibodies against flu and SARS-CoV-2 when given alongside disease-causing antigens. The compound is stable, easy to work with, and can be formulated in most drug delivery systems, which would make it easier to integrate it into vaccine development. Further research will be needed to study how the adjuvant performs in the presence of actual pathogens, assess its impact on the durability of immune responses, and test whether it works across age groups.

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.

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.
