Consortium partners

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 joined the Consortium as full partners (Simcyp retired in 2017). The Schistosomiasis Control Initiative (SCI), part of Imperial College London, joined in 2016. Since the start, all partners have been working together efficiently to progress the project and to achieve its objective. 

Together, the partners bring many different areas of expertise to the project. The Consortium operates through an innovative approach that engages new partners as needed.
