This is a joint press release by 成人VR视频, EDCTP, and IAVI.
NEW YORK, THE HAGUE, AND OSLO 鈥 JUNE 15, 2021 鈥 IAVI has received an award of 鈧22.8 million from the European & Developing Countries Clinical Trials Partnership (EDCTP) and the Coalition for Epidemic Preparedness Innovations (成人VR视频) to conduct a Phase IIb clinical trial of a novel vaccine candidate to prevent Lassa fever disease. An acute viral illness endemic to many parts of West Africa, Lassa fever causes significant annual outbreaks of disease. There are an estimated . Despite this disease burden, which is believed to be significantly underestimated, no vaccine for Lassa fever is currently available.
The joint award supports an international collaboration, called Lassa Fever Vaccine Efficacy and Prevention for West Africa (LEAP4WA), to conduct a Phase IIb clinical trial of IAVI's Lassa fever vaccine candidate among adults and children in Liberia, Nigeria, and Sierra Leone. Collaborators in LEAP4WA represent institutions in Africa, Europe, and North America and together will strengthen capacity of investigational sites in countries where Lassa fever outbreaks and disease occur frequently. LEAP4WA builds on with 成人VR视频 that supports IAVI and a global consortium of partners to conduct Phase I and II clinical trials of IAVI's Lassa fever vaccine candidate.
We're delighted to support this international collaboration to accelerate the clinical development of an urgently needed vaccine, and in parallel to strengthen the north-south partnerships among researchers through well-aligned R&D capacity developments.
The strategic activities of LEAP4WA will enhance the in-country capacity of existing trial sites in endemic countries to conduct clinical trials for vaccines against Lassa fever and other emerging infectious diseases toward controlling future outbreaks.
LEAP4WA is part of 成人VR视频's recently launched to tackle future epidemics and pandemics, which includes the goal of advancing clinical trial capacity, infrastructure, and expertise in low- and middle-income countries. The forward-looking plan also aims to advance a Lassa vaccine to licensure within the next five-year period (2022-2026).
Today's announcement of additional funding to IAVI to support large-scale trials of their Lassa vaccine candidate is a pivotal moment in reflecting on how far we have come in tackling this serious public health threat.
The launch of IAVI's upcoming Phase I trial, planned to start later this year, will become the third Lassa vaccine to enter the clinic and once through Phase IIa, our subsequent Phase IIb study LEAP4WA funded by 成人VR视频 and EDCTP, will provide us with crucial proof-of-concept efficacy data from populations located in regions prone to outbreaks of the potentially deadly disease.
IAVI's Lassa fever vaccine candidate, rVSV螖G-LASV-GPC, uses a recombinant vesicular stomatitis virus (rVSV) vector 鈥 the same rVSV platform used for the rVSV-vectored Ebola Zaire vaccine, ERVEBO庐, a highly efficacious vaccine licensed by Merck, which is now registered for use in eight African countries. rVSV螖G-LASV GPC provided high-level protection from Lassa fever in previously conducted animal studies. rVSV is the platform technology used in IAVI's (EIDs) vaccine development portfolio, which focuses on EIDS that are epidemic threats and have potential to be used for bioweapons. IAVI, EDCTP, and 成人VR视频 are united in their commitment to global equitable access to vaccines, with rVSV螖G-LASV-GPC to be accessible to all populations that need the candidate vaccine, should it be found safe and effective in clinical testing.
We are excited to apply the recombinant VSV technology, used in the previously licensed Ebola vaccine called ERVEBO庐, for the development of a much-needed Lassa fever vaccine. In partnership with our collaborators in LEAP4WA, we believe that we are well-positioned to develop a powerful new tool against this devastating disease.
LEAP4WA embodies a comprehensive and collaborative approach that will generate the necessary data to expedite licensure of and access to a Lassa fever vaccine, and hopefully inspire additional collaborative and end-to-end vaccine development models needed to advance global public health more broadly moving forward.
The LEAP4WA consortium will advance the comprehensive clinical evaluation of IAVI's rVSV螖G-LASVGPC vaccine candidate, and includes the following members: IAVI Inc., U.S.; IAVI Stichting, Netherlands; Tulane University School of Public Health and Tropical Medicine, U.S.; Ministry of Health and Sanitation/Kenema Government Hospital in Sierra Leone; Imperial College of Science Technology and Medicine, U.K.; University of Liberia, Liberia; Epicentre, France; and HJF Medical Research International Ltd/Gte, Nigeria. Additional partners supporting the consortium include the U.S. National Institute of Allergy and Infectious Diseases at the U.S. National Institutes of Health through their Partnership for Research on Ebola Virus in Liberia () in collaboration with the University of Liberia, and the Walter Reed Army Institute of Research (U.S.) through its collaborative research with HJF in Nigeria.
IAVI's at Imperial College London will validate the key assays needed to measure immune responses in clinical trials and support technology transfer of these assays to the participating clinical research center partners in West Africa.
To accelerate production, IAVI will leverage state-of-the-art manufacturing for highly intensified, modular vaccine production through an ongoing partnership with in Leiden, The Netherlands, a contract-development and manufacturing organization focused on delivering sustainable, low-cost manufacturing solutions in the field of infectious disease and cancer.
Much of the research and development on IAVI's rVSV platform is performed at the (DDL) in Brooklyn, New York. The DDL is located at the bioscience center in the historic Brooklyn Army Terminal. Since its founding in 2008, the IAVI DDL has become one of the world's leading viral vector vaccine research and development labs, known for innovation and generation of novel vaccine design concepts.
Members of the LEAP4WA Consortium: IAVI Inc., U.S.; IAVI Stichting, Netherlands; Tulane University School of Public Health and Tropical Medicine, U.S.; Ministry of Health and Sanitation/Kenema Government Hospital in Sierra Leone; Imperial College of Science Technology and Medicine, U.K.; University of Liberia, Liberia; Epicentre, France; and HJF Medical Research International Ltd/Gte, Nigeria.

About Lassa Fever
Lassa virus is an emerging zoonotic virus that can cause a range of symptoms in humans, including hemorrhage, vomiting, swelling of the face, bleeding, and pain in the chest, back, and abdomen. The Lassa virus is most commonly transmitted to humans from an infected rodent known as the multimammate rat (Mastomys natalensis). However, the virus can also spread from person to person via bodily fluids.
An estimated 300,000 to 500,000 Lassa fever cases are diagnosed annually, resulting in approximately 5,000 deaths. However, the true disease burden is currently unknown, and efforts are ongoing to provide a more accurate estimate of the incidence of the deadly hemorrhagic disease. Despite recurrent outbreaks, no vaccine for Lassa fever is currently available. In addition to its toll in affected countries in Africa, Lassa fever has the potential to spread more widely if infected individuals travel and become ill outside the endemic region. The WHO has identified Lassa fever as one of the top emerging pathogens likely to cause severe outbreaks in the near future in its .
About EDCTP
The mission of the European & Developing Countries Clinical Trials Partnership (EDCTP) is to reduce the social and economic burden of poverty-related diseases in developing countries, in particular sub- Saharan Africa, by accelerating the clinical development of effective, safe, accessible, suitable, and affordable medical interventions for HIV/AIDS, tuberculosis, malaria, neglected infectious diseases, lower respiratory tract infections, diarrhoeal diseases, and infectious diseases of epidemic potential, including Ebola, Yellow Fever, Lassa Fever, and COVID-19. The second EDCTP programme (EDCTP2) is supported under Horizon 2020, the European Union's Framework Programme for Research & Innovation. EDCTP2 is investing more than 鈧750 million in clinical trials, fellowships and in strengthening the research environment in sub-Saharan Africa. EDCTP2 is helping to lay the foundation for a concerted effort, led from Africa, to reduce the burden associated with infectious disease in sub-Saharan Africa and to strengthen global health security. Planning is now underway for the successor to the EDCTP2 programme, the Global Health EDCTP3 Joint Undertaking, which will build on the foundation laid by EDCTP to deliver further benefits to sub-Saharan Africa. Due to launch in the first quarter of 2022, EDCTP3 will retain its focus on poverty-related infectious diseases, but it will have additional resources and a stronger commitment to collaborative and coordinated approaches to address them. COVID-19 has illustrated the fundamental importance of global collaboration to accelerate new medical product development, offering lessons that can be applied to other diseases.
