The home page of Medigen Suite shows the products you are allowed to access:

Medigen Suite – Choose Product Screen

For each product, four sections are listed:

• Demo: explore the modules and functionality and select the best configuration for your study.
• Preview: using this mirror system, review your study CRF, test the capabilities, and complete your training to obtain access to Production.
• Production: electronic CRF to collect the study data; access is reserved to users who are trained and authorized.
• Designer: dedicated portal to create your CRF, setup data rules and publish your study; access is reserved to Study Manager.

Clicking on a section will let you choose the study, among those you’re allowed to. A grayed out section means that there are no instances of that kind of study you’re allowed to access.
