AGI projects are projects proposed by AGI members and endorsed by the Steering Committee. They should present first project ideas for strongly collaborative, genuine Ataxia Global projects, and should be translational in character, focussing on trial-readiness.

The next deadline for project proposals is 15 June 2022. You can send your project proposal to ataxiaglobaloffice[at] Please use this template.

These projects proposals will be collected, refined, elaborated and coordinated further by AGI as trial-readiness platforms. These further processing steps will catalyse the collaborative character of the projects. Please note  that AGI is not a funding organisation.

The list of ongoing projects below are supported by AGI. They were submitted after the SCA & ARCA Global conference in October 2020 and have been evaluated by the AGI Steering Committee
