You can edit or delete trial associations as necessary. When editing an association, you can change the details of associated trials that have not  been registered with the CTRP.  You cannot change the details of trials that have been registered, but you can change the association to a different trial, or create a new association.

When you delete an associated trial record, you disassociate it from another trial. The trial record itself is not deleted.
