Fighting against 

Shigellosis

ShigaPlexIM is a collaborative project funded by the European & Developing Countries Clinical Trials Partnership (EDCTP2) Programme supported by the European Union. The project is the joint effort of leading African and European experts with proven track records in research and development of vaccines against poverty-related neglected diseases, including diarrhoeal diseases.

The ShigaPlexIM project aims at advancing the early clinical development of an injectable Shigella vaccine through Phase I and descending age studies with and without an adjuvant in Africa. We will test a safe and highly immunogenic Shigella vaccine, InvaplexAR-Detoxthat has already completed a successful Phase 1 trial in U.S adults without adjuvant where it demonstrated excellent safety and immunogenicity. The current formulation should provide coverage for Shigella flexneri serotypes 2a, 3a and 6. Shigella sonnei LPS will be added at a later stage of development of this product to optimise serotype coverage in future field efficacy trials.

Specific objectives of this project include (i) conduct of a phase Ia/Ib clinical trial in European and African adults with the vaccine administered with or without the mucosal adjuvant, double mutant labile toxin (dmLT) followed by (ii) an age de-escalating phase II in Burkina Faso.

Moreover, specific epidemiologic data will be generated on the incidence of Shi​gella disease in Burkina Faso and Zambia among children under five presenting with moderate to severe diarrhoea at primary healthcare facilities. The results of this project will strengthen the vaccine pipeline against a major diarrhoeal disease and making it available for late stage clinical development.
