At GHTC, we get to read stories every day about incredible innovations in global health. Most of the technologies we see are inventive, some are revolutionary, and a few are so unusual, one might think they were ripped from the pages of a science fiction novel. Now, we’re testing how well you know these global health technologies with our annual Halloween game: the TRICK or TREATment quiz.For each question, we will present a description of a global health technology. Choose TREATment if you believe this innovation exists. Choose TRICK if you think we are trying to pull one over on you and, instead, the product is still in development or is just a figment of our imagination.

The pill, which is the first-ever drug to show antiviral activity against dengue, will also be tested as a treatment method. If the drug is successful in larger-scale trials, ensuring access to the new drug in low- and middle-income countries —especially as the threat of dengue rises in high-income countries alike—will be essential to effectively tackle the disease around the world.The Sabin Vaccine Institute has launched a phase 2 clinical trial for its vaccine candidate against Marburg virus, a lethal filovirus for which there are currently no vaccines or antiviral treatments approved. The trial will take place in Kampala, Uganda, which has experienced various Marburg outbreaks in the past few decades. The single-dose candidate was previously found to be safe and elicit rapid and robust immune responses in phase 1 clinical and non-clinical studies. The ChAd3 platform, which forms the basis of the Marburg vaccine candidate, also undergirds Sabin's Sudan ebolavirus vaccine candidate, which recently received US funding for phase 2 clinical trials. The need for a vaccine against both deadly diseases has been brought to the fore by recent outbreaks.Last week, Gilead Sciences Inc. announced PURPOSE 5, the first phase 2 clinical trial to evaluate an investigational, long-acting HIV prevention option in Europe. Lenacapavir for HIV prevention, compared with a currently used drug combination, could offer a fewer-dose, long-acting solution to individuals who could benefit from pre-exposure prophylaxis (PrEP). Lenacapavir, which can be administered as a twice-yearly injection, is currently approved in combination with other antiretrovirals for HIV treatment in people with multidrug-resistant HIV-1 infection. The study has an intentional focus on recruiting participants who are disproportionately affected by HIV and often underrepresented in clinical trials, given the importance of making available a variety of HIV prevention methods to meet the diverse needs of those who could benefit from PrEP.

Specifically, the awards will go to two intranasal vaccine candidates that are administered as sprays and one self-amplifying mRNA vaccine candidate that is administered as an injection; phase 2b clinical trials of those vaccine candidates could start as soon as this winter. Funding will also go to the development of vaccine patches, cold-chain sample management, genomic sequencing, and increased laboratory capacity.The Coalition for Epidemic Preparedness Innovations (CEPI) is leading an initiative with the biopharma data provider IQVIA aimed at enhancing global research capacity to advance the 100 Days Mission, which aims to be able to respond to the next Disease X (a future pathogen with pandemic potential) with medical countermeasures within 100 days of its identification. Under the initiative, IQVIA will provide tools and resources to support research preparedness in underserved regions during ‘peacetime’ (when there is no ongoing pandemic outbreak) and to support clinical trials during future outbreaks of diseases with pandemic potential. CEPI will fill in gaps to ensure high-quality data are generated during an outbreak response to inform further research.Last week, The Lancet and the Coalition for Preventing Pandemics at the Source announced that they have convened the Commission on Prevention of Viral Spillover, which will work to mobilize decision-makers to support research and policies to prevent future viral spillovers and pandemics following the COVID-19 pandemic, which was the fifth viral pandemic caused by a viral spillover in the last century. The commission, which includes 28 experts in a variety of fields from epidemiology to veterinary medicine to food systems management, will conduct original research and publish a comprehensive report within two to three years on recommendations to prevent such spillovers.

The trial found that mRNA-1083 was similarly effective to two already approved flu vaccines developed by GSK and Sanofi and Moderna’s own SpikeVax COVID-19 vaccine. There were also no new safety concerns reported with the combination vaccine compared to each of the vaccines used alone. A phase 3 trial testing the combination shot will begin before the end of the year with potential regulatory approval in 2025 if successful. The company also laid out its broader efforts on combination vaccines, including a combination shot for COVID-19, flu, and respiratory syncytial virus.The Biomedical Advanced Research and Development Authority (BARDA) has awarded Vir Biotechnology $50 million in Project NextGen funds to advance the development of novel monoclonal antibody (mAb) candidates and delivery solutions for COVID-19 and future pandemic threats.  The new funding will support development of alternative mAb delivery technologies that increase antibody expression relative to existing solutions, which could revolutionize mAb delivery by expanding administration options and shortening development and manufacturing timelines. Four-fifth of the funding will specifically go toward advancing Vir’s next-generation COVID-19 mAb, Vir-7229, through a phase 1 trial, expected to be completed in late 2025, while the remainder will support the discovery of new mAbs against a second pathogen of pandemic potential.The World Health Organization (WHO) last week recommended the R21/Matrix-M malaria vaccine, developed by the University of Oxford. This follows two years after WHO recommended RTS,S, the first malaria vaccine. Both vaccines have a similar efficacy profile and delivery method and are targeted to children, but doses of R21 are expected to be cheaper—between $2.00 and $4.00 compared to about $7.25 now charged for RTS,S. The Serum Institute, which will produce R21, has also announced plans to deliver a much higher volume of doses compared to GSK’s current marketing plans for RTS,S. Although it will take more time to collect further safety monitoring data for R21, the recommendation of a second vaccine will hopefully help to ensure adequate supply for malaria-endemic countries that are planning to integrate a vaccine into their national malaria control plans.

Gritstone’s candidate aims to provide broader and longer-lasting clinical protection than first-generation COVID-19 vaccines by inducing multiple types of immunity against current and future variants of the virus that causes COVID-19.Two recent studies reviewing the efficacy and safety of higher dose regimens of the antimalarial drug primaquine bolster support for increasing doses in malaria-endemic countries. Primaquine has been used against Plasmodium vivax malaria for more than 60 years, but this new research provides the answer to a problem designated by the World Health Organization as a key research priority: how to reduce malaria relapse. The studies found that doubling the currently used dose of primaquine halved malaria relapses, while delivering a similar safety profile to the lower dose regimen, suggesting widespread implementation of higher dosing could have a significant impact on reducing P. vivax malaria relapses, deaths, and transmission in endemic countries.New research into an innovative injected hydrogel drug method for treating HIV offers hope of a completely novel management method that could drastically reduce the frequency of treatment and eliminate the need for daily pills, greatly improving the quality of life of people living with HIV. The researchers found that one injection of the gel in mice was enough to maintain effective and lasting concentrations of the drug lamivudine for 42 days with nearly no side effects by ensuring the drug was released slowly and consistently in the body. Further tests will look at the hydrogel used in combination with others drugs to prevent HIV as well as simultaneously address HIV and hepatitis B.

The company’s Lyme disease immunoassay could simplify diagnosis by eliminating the need to perform one of the two steps now used in the screening and confirmatory testing process. Kephera’s immunoassay for Chagas disease is designed to monitor treatment response in patients, as current drugs vary in efficacy in adults with chronic infections. It is being developed both for laboratory use and use in the field.A phase 1 trial evaluating a novel preventive HIV vaccine candidate, VIR-1388, has begun enrollment in the United States and South Africa. VIR-1388 is designed to prompt the immune system to produce T cells that can recognize and signal an immune response to prevent the virus from establishing chronic infection. It delivers vaccine material using a cytomegalovirus (CMV) vector, whose discovery and development was funded by the National Institute of Allergy and Infectious Disease (NIAID). Because CMV, while harmless, remains detectable in the body for life, researchers hope this vector will help the body retain the vaccine material for a longer period of time, overcoming the waning immunity seen with other candidate vaccines. The trial is sponsored by Vir Biotechnology with support from NIAID and the Bill & Melinda Gates Foundation.Last week saw the launch of a third phase 1 clinical trial of the ChAdOx1 vaccine candidate for Middle East Respiratory Syndrome (MERS). If eventually approved, the vaccine would be a game-changing tool against the viral illness, for which there are no approved vaccines or treatments, and which is recognized by the World Health Organization as a priority pathogen with epidemic potential, especially in light of new cases reported this year. The University of Oxford’s Pandemic Sciences Institute started developing the vaccine for MERS before the COVID-19 pandemic, and the research for ChAdOx1, which was put on pause during the pandemic, enabled the rapid development of the Oxford/AstraZeneca vaccine for COVID-19.
