Summary:

STOPENTERICS aims at providing novel prophylactic solutions by imposing a two-fold paradigm switch in the development of vaccine candidates against Shigella and ETEC:

  1. to break the dogma of serotype-specific protection and
  2. to improve the immunogenicity of some already identified antigens.

In addition, since a set of new vaccine candidates corresponding to novel strategies have already reached an advanced stage, the consortium is in a position to achieve a proof of concept early on in the program. The program integrates basic research, particularly genomics, transcriptomics, proteomics, high-throughput technologies, and synthetic chemistry to identify novel antigens and generate new vaccine formulations, as well as immunology and development of cell-based and animal models to help rationalize R&D and prepare for transition to phase 1 trials. A particular effort will be dedicated, throughout the program, to immunomonitoring of natural Shigella and ETEC infections in order to generate and validate novel and reliable correlates of protection. Therefore, STOPENTERICS will adopt a pragmatic modus operandi illustrated by the strong momentum imposed to bring innovative candidates as quickly as possible through the R&D pipeline, including clinical trials carried out both in the North and in the South.
A particular strength of STOPENTERICS is its integration of a broad spectrum of expertise offered by a coalition of groups from Europe, Middle East, Asia and Africa in Shigella and ETEC biology, pathophysiology, immunology and vaccine testing. STOPENTERICS will also team up with two premier vaccine companies: Novartis, through the Novartis Vaccines Institute for Global Health, and Sanofi-Pasteur, both engaged in the consortium as scientific partners.
