Replace randomization for subjects

If a subject has been withdrawn from a study, you can replace them with a new subject that is assigned to the same treatment arm.

Before you work with this feature

Be aware of the following:

• Only users with the Replace Randomization permission can perform replacement and view a replacement randomization.
• Once a subject's randomization has been replaced, the option to undo withdrawal is not available.

1. Access your study in a specific mode
2. Along the top, select Subjects.
3. If you have access to multiple sites for the study, from the Site filter, select a specific site.
4. In the table, select the checkbox next to the subject you'd like to replace the randomization for.
5. Above the table of subjects, from the Manage drop-down, select Replace Randomization Number.
6. In the Confirmation dialog, select Yes.
   The subject's status updates to Withdraw / Rand Replaced in the Subjects list, and Replacement Randomization is displayed on the Subject History sidebar.
