When should I send initial shipments to sites?

You have two options: After each site is activated, and after subjects start a specific visit.

You make a choice when you specify supply settings.

• When you choose site activation, sites typically receive supply before they enroll subjects, so they don't have to turn subjects away due to lack of supply. However, if a site never enrolls a subject, supply is sent to the site unnecessarily.
• When you choose a specific visit, you send supply only to sites that enroll subjects. We recommend this option, if your study has a number of visits prior to randomization. This option doesn't work if randomization occurs on the same day as screening or soon after screening.
