I have couple of questions to the Privacy settings in the Substance request form.

The privacy setting in the form is set to "public" by default. I understand that if the substance is part of the investigational medicinal product currently under development, the Privacy setting could be adjusted accordingly i.e. "public" vs "restricted".

1. is there a minimum of fields that must be set to "public"?
2. where i.e. in which databases will the data be restricted from publishing?
3. can the privacy setting be changed post registration of the active substance?
