Introduction and Background of the Project
Schistosomiasis, also known as bilharzia and endemic in 78 developing countries, is a chronic inflammatory neglected tropical disease caused by parasitic worms. The disease affects more than 258 million people, including 100 million children, globally. It is one of the most prevalent tropical diseases in the world after malaria, and represents an important health burden in developing countries, especially in Africa where more than 90% of the infections occur.
The current gold standard recommended treatment for schistosomiasis, praziquantel (PZQ), is available in oral tablets for adults and children, but younger children under 4 years cannot be treated due to missing clinical data. In addition, a pediatric formulation of praziquantel that would be appropriate for preschool age children, infants and toddlers, and would permit accurate dosing and enhanced compliance in these patients is non-existent and highly needed. The development of a new pediatric formulation of praziquantel is to be seen in the context of the WHO’s 2020 Roadmap and with respect to the initiative of “Uniting to combat Neglected Tropical Diseases” under which the global community agreed on control and elimination of schistosomiasis.
The Pediatric Praziquantel Consortium is an international not-for-profit partnership that aims to reduce the global disease burden of schistosomiasis by addressing the medical need of infected preschool-age children. Its mission is to develop, register and provide access to a suitable pediatric praziquantel formulation for treating schistosomiasis in this age group. The pediatric formulation under investigation has been designed to be smaller, exhibit an improved palatability and be orally dispersible compared to the current commercial formulation.
The Consortium was established in July 2012 by Merck KGaA, Darmstadt, Germany (Merck KGaA), Astellas Pharma Inc. (Astellas), Swiss Tropical and Public Health Institute (Swiss TPH) and Lygature (formerly TI Pharma). At the beginning of 2014, Farmanguinhos and Simcyp, a Certara company, joined the Consortium as full partners. The Schistosomiasis Control Initiative (SCI), part of Imperial College London, joined in 2016.
All partners are bound by a Consortium agreement, which arranges their roles and responsibilities and includes a formal governance structure with a Consortium Board as the highest decision-making body, and Lygature as independent Coordinator. An external expert panel is called by the Consortium prior to each clinical development stage to provide an independent evaluation of the project. The partners have formed a core project team, led by Merck KGaA, comprising one representative of each partner and/or expertise area that meets every month. The core project team is supported by various subteams focusing on specific technical and operational aspects to implement the consortium’s program.
How can your partnership (project) address global health challenges?
In order to tackle the important public health problem of schistosomiasis, the non-profit Pediatric Praziquantel Consortium has been formed in July 2012 to develop a pediatric formulation of praziquantel. The project will contribute to the overall goal of control and elimination of schistosomiasis by developing a product urgently required for the treatment of preschool-age children, infants and toddlers, a population that is currently being considered by WHO to be included in treatment campaigns. The development and registration of a new pediatric formulation of praziquantel is regarded by the Consortium as a cornerstone to fulfill the 2020 WHO commitment to address the health burden that schistosomiasis represents and the importance of controlling disease-related morbidities. To achieve this commitment, several measures need to be integrated among which making chemotherapy treatment available to all age groups is an important part of.
What sort of innovation are you bringing in your project?
The Pediatric Praziquantel Consortium combines the best science and most experienced public and private partners to develop and register a new pediatric formulation of praziquantel, the current gold standard treatment for schistosomiasis. It has developed new oral dispersible formulations of praziquantel that can be easily administered to preschool-aged children, infants and toddlers, exhibit improved taste, and are able to withstand the challenges presented by a tropical climate. The Consortium is currently conducting the clinical phase II in Ivory Coast, and in the second quarter of 2017 the project will move into the clinical development phase III.
Role and Responsibility of Each Partner
Merck KGaA (Darmstadt, Germany) leads the program and brings expertise and support related to praziquantel, including resources from different areas (drug product manufacturing, pre-clinical, clinical, regulatory) needed for clinical development and to efficiently execute the project. Astellas contributes by providing its innovative pharmaceutical technologies in the area of pediatric drug formulation development as well as clinical development in children. Swiss TPH brings extensive experience in helminths biological and pharmacological research, epidemiology and clinical research in endemic regions. The governance is facilitated by Lygature, a Dutch non-profit organization and independent party with an extensive portfolio of international public-private partnerships in drug research and development, including in the area of neglected diseases. Farmanguinhos, the federal governmental pharmaceutical laboratory of the Fiocruz Foundation in Brazil, brings unique expertise to produce and distribute the new pediatric formulations product in endemic countries. Simcyp, a Certara company, brings expertise in pharmacokinetic modelling for better predicting the appropriate dosage for use in the pediatric clinical trials. SCI, part of Imperial College London, provides the necessary expertise to define and execute the access strategy and plan as well as to initiate and implement NTD control and elimination programs in Sub-Saharan Africa.
