Is the compulsory annex also used for the evaluation, e.g.: we do not have to repeat what we said, to cut down the number of pages? What level of information is expected at stage 1?

Annexes are to be uploaded with the full proposal, and yes, accessible for the evaluators. You do not have to repeat everything in the proposal body, but can be more concise there and make cross references to the annexes. In stage 1, you must be very brief, as the overall page limit is the same for all proposals, including those that entail clinical study elements.SOCIETY
