SCI Foundation is now Unlimit Health. Learn more about what the change means for our ongoing efforts to eliminate neglected tropical diseases

As part of the Pediatric Praziquantel Consortium, Unlimit Health is proud to announce that the first preschool-aged child has been treated with arpraziquantel, a newly developed pediatric treatment for schistosomiasis. This milestone marks a significant step forward in addressing one of the world’s most prevalent parasitic diseases.
Schistosomiasis, also known as bilharzia, affects an estimated 250 million people worldwide, including approximately 50 million preschool-aged children, mainly in sub-Saharan Africa. The disease can cause malnutrition, anaemia, stunted growth, and cognitive impairment. In severe cases, it can lead to chronic organ damage or death. Until now, no child-friendly treatment was available for preschool-aged children, leaving millions at risk. According to the WHO guideline for the control and elimination of schistosomiasis, children aged two years and older should be included in preventive chemotherapy for schistosomiasis.
Arpraziquantel, the new pediatric treatment option, is a 150 mg dispersible tablet designed specifically for children aged three months to six years. It is palatable and easily administered to preschool-aged children. It is also stable in hot and humid climates, making it ideal for use in endemic regions.
Arpraziquantel was granted a positive scientific opinion by the European Medicines Agency (EMA) in December 2023 and included in the WHO’s List of Prequalified Medicines in May 2024. Inclusion in the WHO’s List of Essential Medicines Products is expected in 2025.
“At Unlimit Health, we are proud to have supported the attainment of this milestone, representing a key step in addressing a long-term unmet medical need and expanding schistosomiasis treatment to a previously underserved group. Unlimit Health is committed to supporting integration and access to treatment for all at-risk groups and will continue to do so as part of our ongoing work the ADOPT country teams and PPC partners,” said Jenny Burrill, Unlimit Health’s Deputy Director, Access.
Treating preschool-aged children is essential to lowering the disease burden on individuals and public health systems. Early intervention prevents complications, possibly reducing the need for costly medical care later in life. It also improves educational outcomes and long-term productivity, potentially generating cost savings in affected countries.
“As the first country to introduce arpraziquantel to children under five, Uganda has reached a historic milestone, expanding access to a group that has never previously benefited from treatment,” said Prudence Beinamaryo, Programme Manager, Bilharzia & Worm Control, Ministry of Health Uganda.
Dr Hilda Kyarisiima, Senior Medical Officer & ADOPT Programme Principal Investigator, Ministry of Health Uganda, added: “Lessons from these first treatments in Uganda will inform future scale-up and significantly contribute to achieving the schistosomiasis targets outlined in the WHO NTD Roadmap 2030.”
The first treatment was administered in Uganda as part of the Consortium’s ADOPT programme, an implementation research study that focuses on the integration of arpraziquantel into existing healthcare platforms. The treatment is being introduced through the country’s NTD Mass Drug Administration Platform. The overall aim of the ADOPT study is to prepare for the widespread introduction of arpraziquantel in schistosome-endemic communities. Beyond Uganda, the introduction of arpraziquantel will be extended to other sub-Saharan African countries, starting with Côte d’Ivoire, Kenya, Tanzania, and Senegal.
The Consortium is working in close collaboration with local ministries of health and global partners to facilitate equitable and sustainable access to arpraziquantel. The treatment will be available on an at-cost basis in sub-Saharan African countries, supporting long-term, sustainable health outcomes. This effort contributes to the elimination of schistosomiasis as a public health problem and thereby also to the United Nations’ Sustainable Development Goals (SDGs), in particular SDG 3 (Good Health and Wellbeing) and SDG 17 (Partnerships for the Goals).
