TOKYO, March 18, 2025 -- The Global Health Innovative Technology (GHIT) Fund announced today a total investment of approximately JPY 1.7 billion (USD 11.4 million1) in five projects for the development of schistosomiasis diagnostics and drugs for neglected tropical diseases (NTDs). 2
Investment total of approximately JPY 780 million (USD 5.2 million1) for the development of diagnostics for schistosomiasis
Schistosomiasis is one of 21 NTDs that affects approximately 250 million people worldwide, with 90% of cases occurring in Africa. People become infected through contact with contaminated freshwater, allowing the parasite to penetrate their skin.. Among the five species of schistosomiasis causing the disease, two are widely distributed on the African continent: Schistosoma haematobium, which infects the urogenitary tract, and Schistosoma mansoni, which infects the intestines and liver. Current diagnostics face challenges such as low sensitivity and quality issues, making it difficult to accurately assess the infection status. To address this issue, the GHIT Fund had decided to invest approximately JPY 780 million (USD 5.2 million1) in two projects to develop new diagnostics for schistosomiasis led by Drugs & Diagnostics for Tropical Diseases, a nonprofit organization based in San Diego, California, USA, in collaboration with Medical & Biological Laboratories Co., Ltd., a Japanese manufacturer of clinical diagnostic kits and reagents, Nagasaki University Institute of Tropical Medicine, the Kenya Medical Research Institute, and the Noguchi Memorial Institute for Medical Research.
The project will advance the development of a rapid diagnostic test (RDT) for Schistosoma mansoni, leveraging previous research findings and evaluating the diagnostic performance of the candidate RDT in endemic regions of Africa. In addition, the project team will develop a new serological RDT for Schistosoma haematobium. These tests are expected to be used as a low-cost, easy-to-use point-of-care (POC) diagnostic to support decision-making for Interruption of Transmission/Stopping Mass Drug Administration (MDA) and for subsequent surveillance of the disease.
In addition, the GHIT Fund will invest in the following three R&D projects for a total amount of approximately JPY 932 million (USD 6.2 million1):
1) Phase I clinical trial project for dengue vaccine by VLP Therapeutics, Inc. and Nagasaki University.
2) Screening project against chikungunya by Medicines for Malaria Venture (MMV) and Eisai Co., Ltd.
3) Screening project against Chagas disease by Drugs for Neglected Diseases initiative (DNDi) and Shionogi & Co., Ltd.
Please refer to Appendix 1 for detailed descriptions of these projects and their development stages.
As of March 18, 2025, the GHIT Fund has invested in 35 projects, including 14 discovery projects, 12 preclinical projects and nine clinical trials.4 The total amount of investments since 2013 is JPY 37.5 billion (USD 251 million1) (Appendix 2).
1 USD1 = JPY149.63, the approximate exchange rate on February 28, 2025.
2 These awarded projects were selected and approved as new investments from among proposals to RFP2023-002 and RFP2024-001 for the Product Development Platform and the Screening Platform, which were open for applications from June 2023 to July 2024.

Appendix 1. Project Details
ID: G2024-202
Project Title | In Support of WHO Schistosomiasis Control and Elimination Programs: Progressing a TPP-compliant serological test for Schistosoma mansoni to Field Testing and Manufacturing Process Development. |
Collaboration Partners | 1. Drugs & Diagnostics for Tropical Diseases (DDTD) (USA) 2. MBL, Medical & Biological Laboratories Co., Ltd. (Japan) 3. Nagasaki University (Japan) 4. Kenya Medical Research Institute (Kenya) 5. Noguchi Memorial Institute for Medical Research (Ghana) 6. Big Eye Diagnostics, Inc. (USA) |
Disease | Schistosomiasis |
Intervention | Diagnostics |
Stage | Product Development |
Awarded Amount | JPY 472,729,041 (USD 3.2 million) |
Status | Continued project |
Summary | [Project objective] The overarching objective of this project is to deliver a fully TPP-compliant, easy-to-use, low-cost point-of-care test able to detect IgG1-type antibodies raised by the human host against selected S. mansoni antigens as an indicator for current or prior infection. The RDT delivered at the end of G2024-202 will have the required sensitivity and specificity to support Schistosomiasis monitoring, evaluation, and surveillance efforts in hypo-endemic areas post-MDA where stool-based or antigen-based diagnostics struggle to accurately determine disease prevalence.
[Project design] -Objective 1: This first activity is aimed at defining the optimal use case(s) for our new serological test: Since serological testing is a new approach for schistosomiasis control and elimination programs, this work will be modelled in as much as appropriate on other NTDs that have already incorporated serological testing in their programmatic concepts (onchocerciasis, lymphatic filariasis, trachoma). -Objective 2: In the predecessor project, G2023-110, MBL produced the S. mansoni antigens and positive control antibodies in R&D grade quality. The production will now be moved to larger scale and ISO/QMS grade quality. -Objective 3: Given that the two prototype tests delivered at the end of G2023-110 (one for each S. mansoni antigen) already meet the TPP criteria, only limited further optimization work will be required, which may include generating and evaluating a biplex test as an alternative to the two singleplex tests. -Objective 4: Evaluate the laboratory diagnostic performance of the candidate RDT using extended patient sample panels and compare the results with egg count, PCR, CCA and/or CAA data as available, and determine the concordance with laboratory-based serological assays (ELISA/MBA). -Objective 5: Follow the clinical study plan established in Objective 1 to evaluate the diagnostic and operational performance of the candidate RDT in both endemic and non-endemic regions of Kenya and, potentially, Ghana. -Objective 6: A ISO13485-compliant automated large-scale manufacturing process will be developed by DDTD, modeled on those we have previously put in place for other tests. BEDx will then conduct an independent validation of the manufacturing process by producing 3 pilot lots of 10'000 units each, and quantifying the inter-lot consistency. |
