In advance of the 150th session of the World Health Organization (WHO) Executive Board, GHTC is urging WHO and member states, as part of the WHO road map for neglected tropical diseases (NTDs), to address key gaps is our arsenal of NTD interventions—including diagnostic, treatments, and pediatric therapies—by increasing investments in NTD R&D and improving WHO guidance and regulatory processes for in-vitro diagnostics. 

January 24, 2022

The following statement focuses on the 150th World Health Organization Executive Board meeting agenda item 10: “Road map for neglected tropical diseases 2021–2030.”

Neglected tropical diseases (NTDs) are inextricably linked to poverty and inequality. These diseases exact a heavy toll, causing chronic illness, severe disfigurement, blindness, and death. More than 1.5 billion people are estimated to require interventions against NTDs each year with many existing tools inadequate to effectively screen and treat populations in low-income and low-resource settings. Increased attention in recent years has brought new resources to the fight against NTDs and fueled research breakthroughs. Yet, very significant gaps remain in the arsenal of tools needed to control and eliminate these diseases, underscoring the need for research and development (R&D) of new tools. COVID-19 has also significantly disrupted interventions and activities across the entire spectrum of research and essential health services for NTDs. Leaders must demonstrate greater urgency to ensure that the progress made over the past decade is not reversed due to challenges caused by the pandemic.

Therefore, GHTC calls on the World Health Organization (WHO) and member states to:

  1. Address the current diagnostic gaps for NTDs. The Diagnostic Technical Advisory Group for Neglected Tropical Diseases recently published a number of target product profiles, and more guidance and support from WHO will be necessary to spur the development of new diagnostic tools. We urge WHO and member states to work together to explore regulatory and manufacturing pathways to facilitate prequalification and regulatory approval of in-vitro diagnostics. 
  2. Support programs that help catalyze innovation and build capacity to develop new drugs, vaccines, and other health technologies, and urge WHO to facilitate greater coordination across the full scope of diseases. Accelerated programmatic action could advance scientific understanding for developing new tools, improving strategies, and strengthening service delivery. We urge member states to fill key gaps by investing in R&D for new and improved treatments and prevention tools, including therapies designed for children and shorter, simplified regimens with fewer side effects.

World Malaria Day 2024: Quiz on malaria innovations

Written by Marissa Chmiola / GHTC
Read time:
Malaria is one of the world’s oldest and deadliest diseases. Thanks to international efforts to develop and scale up prevention tools and treatments, significant gains have been made over the past few decades in fighting this dangerous disease. But challenges, such as growing drug and insecticide resistance, climate change, and disruptions from COVID-19, have hampered control efforts. While both malaria cases and deaths steadily declined from 2000 to 2019, since then, cases have been on the rise and reported deaths have not returned to pre-pandemic levels—indicating progress against the disease has stalled and underscoring the need for continued research and development of new tools.In recognition of World Malaria Day, test your knowledge of this deadly disease and the innovations being advanced to end malaria:

The test, STI-Scout, is designed to detect and differentiate between Neisseria gonorrhoeae and Chlamydia trachomitis and can provide results in only 30 minutes using urine samples or vaginal swabs at less than half the cost of other available tests. The test uses a proven isothermal technology that was validated for SARS-CoV-2 detection. Last week, EuBiologics and the International Vaccine Institute (IVI) announced that the World Health Organization (WHO) had prequalified Euvichol-S, an improved oral cholera vaccine produced with a simplified method that will hopefully help to address the rise of cholera outbreaks globally and a dire vaccine supply shortage. The vaccine, whose development was supported by the Bill & Melinda Gates Foundation, is produced in a way that can improve formulation and manufacturing productivity by 40 percent compared to the company’s prior oral cholera vaccine and demonstrated efficacy in a Phase 3 trial in Nepal last year. The prequalification paves the way for United Nations agencies and Gavi, the Vaccine Alliance, to buy the vaccine for countries experiencing outbreaks.The New Nets Project, funded by Unitaid and The Global Fund to Fight AIDS, Tuberculosis and Malaria, recently reported results from several pilot studies showing that a pair of second-generation bed nets tested in malaria-endemic areas helped to prevent up to 13 million additional cases of malaria, saving close to 25,000 lives—exciting news that comes as malaria cases, as well as resistance to the standard insecticide used to treat nets, rise globally. The studies found that the new nets, the Interceptor G2 and Royal Guard—which both use dual insecticides to address resistance—were between 20 and 50 percent more effective than traditional nets, which only use pyrethroid insecticide, in reducing mosquito exposure and reduced the risk of infection by up to 55 percent. Although the new nets are more expensive, the additional cost seems to be offset by the public health savings of malaria prevention. Researchers expect malaria parasites to eventually become resistant to the new nets, highlighting the need for continued research into other methods of vector control, as well as ensuring population-scale protection through vaccination.
