The roadmap lays out the need for five broad and intersectional streams of work from virology to financing that will be necessary to break down the siloes of current vaccine development to achieve better coordination, accountability, and access. The initiative comes as a response to the COVID-19 pandemic, which is the third time in two decades that a coronavirus has become a public health crisis.A man in Germany has become at least the third person living with HIV formally declared HIV-free after undergoing a procedure in 2013 to replace his cancerous bone marrow cells with donor stem cells that contained a mutation making them effectively HIV-resistant. There remain questions about the full effects of the transplant and the factors behind the successful elimination of HIV in the body, even after follow-up studies. Experts say it is unlikely this procedure would ever be rolled out widely in people without leukemia due to high risk of a person rejecting donor marrow, but other ongoing and planned studies are looking at the potential of genetically modifying a patient’s own stem cells to include the HIV-resistant mutation.The United States is seeing a concerning rise in cases of syphilis, which has seen various cycles of rises and declines over the past century. There are few researchers that study syphilis, and the development of new diagnostics, treatments, and preventive tools has proved challenging because of past inability to grow the fragile Treponema pallidum bacterium that causes the disease in a lab and because of the virus’s ability to evolve resistance to antibiotics. A new technique that allows for lab-grown bacteria along with recent, promising studies of treatments and diagnostics for the disease provide hope. However, there is wide agreement that a vaccine is needed to eliminate the disease and the potential of resistance, and researchers are far from introducing a potential candidate.

The US Agency for International Development (USAID) released a new report on its global health research and development (R&D) programs for fiscal year 2022 that includes unprecedented insight into the product development programs the agency supported—and highlights the need for additional, dedicated resources for global health research.Why it matters: The report gives insight into an agency that is a key sponsor of global health product development.Due to a lack of commercial incentive for industry investment, most global health research is supported by public funders, most notably the US government.Several US agencies support global health research, but USAID is the only agency with a mandate to improve global health and development. The agency excels at pushing products through the end of the research pipeline and advancing tools to suit the needs of people in low-resource settings.What’s new: This report includes an unprecedented 13-page appendix detailing USAID’s individual product-level investments. By our count, USAID supported at least 59 products in 2021 covering multiple health areas and product types.By the numbers: In 2021, USAID spent US$165 million in baseline funding and $50 million in COVID-19 supplemental funding on health product development and research to assess the best way to implement new products and practices.Research spending from baseline funds increased slightly over the prior year (+$4 million) — but continued to decline as a proportion of total global health spending. In 2021, proportionate spending on research dropped slightly to 5.1 percent, continuing a years-long pattern. If the trend continues, GHTC estimates that proportionate spending on R&D will drop to 4.2 percent by 2026 unless Congress passes a policy like the Supporting Innovative Global Health Technologies (SIGHT) Fund to direct more dedicated funding to R&D.Our take: GHTC applauds the release of the report and the additional detail provided by USAID. We call policymakers’ attention to the continued need for additional, dedicated resources for global health research at USAID that this report exposes.

2022 G-FINDER report highlights the inadequacy of global health R&D funding: GHTC offers key takeaways for the global health communityThe release of the 2022 G-FINDER report sheds light on current funding trends in global health research and development (R&D). Despite hard-won advocacy victories by GHTC and the global health advocacy community, neglected diseases are living up to their moniker from a funding standpoint, as global investment in HIV/AIDS, tuberculosis (TB), malaria, and neglected tropical diseases (NTDs) remains far below levels required to overcome these persistent and devastating health threats. The new report highlights several new and ongoing funding trends. GHTC has identified three findings of particular importance to the global health research community.Funding for NTDs dropped precipitously; funding shortfalls for HIV/AIDS, malaria, and TB persist.Funding for NTDs included within the G-FINDER scope decreased by 10 percent in 2021, falling to their lowest total since 2009. NTDs impact more than a billion people each year, disproportionately afflicting women and children. The reduction in funding is particularly alarming given that many of the targets set in the WHO roadmap on NTDs (2012-2020) have not been met. Outside of NTDs, funding for malaria saw a substantial 5.7 percent dip, HIV/AIDS investment experienced a modest uptick of 2.7 percent, and TB funding remained virtually flat, dipping less than a tenth of a percent. While these three diseases receive more resources than NTDs, their funding levels are significantly below that which is needed to overcome these health crises and reach global health and development targets, like the Sustainable Development Goals.Funding for Product Development Partnerships (PDPs) declined for the fourth consecutive year.PDPs are the leading engines of medical innovation for diseases that lack sufficient commercial market incentives. Thus, it is distressing to see that neglected disease R&D funding for PDPs fell by 18 percent in 2021, continuing a multiyear backslide. Current PDP funding sits 40 percent below its peak, which was 13 G-FINDER cycles ago. The most recent dip was driven by reduced investment from large donors like the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, and the US Agency for International Development (USAID). These findings also highlight the need to further diversify funding sources for PDPs, as well as global health R&D more broadly. Specifically on the US government funding front, PDP funding was not the only area in which USAID funding declined. Neglected disease R&D funding from the agency reached a record low, further highlighting the need for additional mechanisms within USAID to facilitate supporting medical innovations for unmet needs. During the virtual launch event for the report, keynote speaker Dr. Peter Hotez noted the vital role that US agencies like USAID and the US National Institutes for Health play in the global health R&D ecosystem.Funding for platform technologies and non-disease-specific investment is on the rise. For the seventh consecutive year, funding for non-disease specific (NDS) R&D increased, rising by 5.6 percent. Specifically, investment in platform technologies grew for the fourth consecutive year and now accounts for 22 percent of NDS funding. Much of the past year’s growth was buoyed by an increase in drug-related platform technologies, which historically received the smallest share of funding. This trend dovetails with a larger shift of investments toward drugs, as overall drug R&D funding eclipsed vaccine R&D funding for the first time in 2021.Overall, the global health advocacy community has made incredible strides in protecting and growing funding for global health innovation. This past year in the United States, GHTC helped support the passage of a global health research-friendly fiscal year 2023 omnibus package, which included significant funding increases across nearly every line relevant to global health R&D, as well as complimentary directives that will support global health R&D across several agencies. However, the challenges of competing global interests and tough funding environments are formidable, as shown by the G-FINDER report. This coming year presents a number of strong opportunities to elevate attention and support for resources for global health innovation, including United Nations High-Level Meetings on TB and universal health coverage. We urge leaders around the world to step up and invest in lifesaving global health R&D, and our advocacy community partners to continue to hold the world accountable for ensuring health and health equity for all. 

Next week, the World Health Organization’s (WHO’s) 152nd Executive Board (EB) meetings kick off in Geneva, with delegates and civil society representatives participating in person for the first time in two years. Recent months have seen a shift away from COVID-19 and an increased focus on long-term reforms to the broader global health architecture. While the dialogue around designing global frameworks and new mechanisms to address future health threats is vital, many of the discussions on poverty-related and neglected diseases are seemingly absent from this year’s discourse.  Here are the four issues to watch at this year’s meetings: Continued focus on global health security  2022 was a fruitful year for advancing two processes that will significantly influence the future of pandemic response. First, the intergovernmental negotiating body tasked with shepherding the Pandemic Accord process developed its first conceptual draft for the new framework. This comes following multiple public hearings, member state negotiations, and consultations on specific elements including equity, access and intellectual property, and antimicrobial resistance. Encouragingly, the document includes some strong research and development (R&D) focused language and recognizes R&D as an integral pillar of health preparedness. However, the current draft emphasizes downstream response measures such as manufacturing and registration, with less of a focus on early-stage research, clinical development, and even post-registration access and delivery of health tools. Additional focus on early-stage discovery research, clinical development, regulatory processes, and access and delivery of medical countermeasures is needed to ensure the type of true end-to-end approach critical to global health security. The second major global health security focused process has been centered around targeted amendments to the International Health Regulations. This policy discussion primarily focused on changes to provisions on trade and travel health certificates, as well as data-sharing and reporting requirements. Though perhaps less prominently discussed, disputes over intellectual property, in particular those centered on genetic sequence and pathogen sharing, remain major barriers to consensus. Both of these processes will be debated during EB, and we can expect a concerted effort to clearly delineate these processes and advance dialogues around defining the terminology and scope of both endeavors.  Limited progress on the implementation of the clinical trials resolution Last year, member states passed a resolution on clinical trials with the intent to build on lessons learned from the COVID-19 pandemic. The crisis drove a surge in funding for clinical research on COVID-19 tools, but we also saw many trials that were not large enough or that failed to employ consistent protocols and outcome measurements across geographies, making it difficult to pool and compare data to turn conclusions into medical practice. Among other matters, the resolution urged countries to better coordinate research, standardize protocols, improve reporting on trial registration and results, and work to increase clinical trial capacity globally, particularly in low- and middle-income countries—though none of these actions are binding. It also requested that WHO develop a global action plan to strengthen clinical trial practices to be presented for consideration at this year's assembly.EB will provide a chance to level set the current status of the implementation of the clinical trials resolution and figure out which elements of the framework could be improved. Previous discussions suggest that the current progress in implementing the resolution has been limited. During consultations held last fall, member states highlighted gaps in data on specific population groups and disease targets, as well as gender biases in data, which may result in these groups being precluded from access to needed interventions, as a point of inequity that must be addressed. The public consultation also noted the crucial importance of strengthened national regulatory authorities and national ethics committees, as well as increased international collaboration and coordination for efficient funding of agreed-upon priorities for multinational and multiregional trials, where appropriate.  The EB now has a chance to build on the progress and push WHO to follow through on their global action plan and for member states to support mechanisms like the WHO International Clinical Trial Registry Platform to push this agenda forward.  A new resolution on diagnostics could be passed New on the docket this year is a resolution that focuses on the development of—and access to— diagnostics. A recent Lancet report sounded alarm bells, highlighting that almost half of the global population has little or no access to diagnostics. The COVID-19 pandemic has clearly shown that a country’s diagnostic capacity is directly linked to its ability to respond to pandemics with appropriate public health measures and effective monitoring of emerging variants. Given the depth of the challenge, sustained access to quality, affordable diagnostics will require multi-decade prioritization, commitment, and investment.  This resolution is a good first step in acknowledging the need for more political will in addressing the diagnostics gap. Notably, it urges member states to develop a National Essential Diagnostics List, adapting the WHO Model List of essential in vitro diagnostics and the WHO List of Priority Medical Devices. The resolution further urges countries to invest in R&D, expanding manufacturing capacity for diagnostic medical devices and surveillance and strengthening international collaboration and assistance during epidemics and pandemics.  The resolution also calls on WHO to support member states to strengthen national and regional regulatory systems for diagnostic medical devices, collect data on the affordability and availability of essential diagnostic medical devices, and consider and support mechanisms for procurement that will enable access to high-quality, affordable diagnostic technologies for all member states. Some hurdles to approving this resolution remain, including outstanding disagreements on whether to include provisions pertaining to intellectual property and access, but there appears to be broad support from member states to get this resolution across the finish line in Geneva.  UHC back in the spotlight Universal health coverage (UHC) is also back in focus for this year’s EB, especially with September 2023 marking the halfway point of the timeline to reach the Sustainable Development Goals (SDGs) and leaders preparing for a United Nations High-Level Meeting on them at this year’s General Assembly. While some progress toward the SDGs has been made, the COVID-19 pandemic caused major disruptions in both health services and the development of health system capacities globally.  From a research perspective, a report by WHO ahead of EB highlighted that research and innovation continues to play a crucial role in UHC. Inequitable access to medical products is among the main causes of financial hardship in many lower- and middle-income countries. The report also notes how the recent World AIDS Day 2022 campaign highlighted the dangers of these inequalities, calling on global leaders and citizens to equalize access to essential HIV services, particularly for children and key populations, in order to end AIDS as a public health threat.  EB is a chance to hit reset on the UHC dialogue and for countries to reaffirm their commitment to the SDGs. It is also an opportunity to reassert that health system strengthening supports all health areas, including pandemic preparedness and poverty-related and neglected diseases. It is vital that leaders break down silos and take a more holistic approach to ensure progress toward advancing the global development agenda and 2030 targets. As discussions on global health architecture reforms advance, and new investments in pandemic preparedness are made, it is vital that global decision-makers ensure the benefits of these resources are also leveraged to benefit the fights against tuberculosis, HIV, malaria, and neglected tropical diseases.
