The Signant Health IRT mobile app allows clinical trial users to work with Signant Health's eClinical system for randomization and trial supply management using a handheld device. Users can randomize subjects, record visits, verify the study medications dispensed, and complete other transactions all through mobile app. Bar code scanning capabilities can be used to automate dispensation confirmation at sites. If you are a clinical trial site that is using Signant Health for trial supply management, please check with your coordinator or with the Signant Health helpdesk to determine if this is compatible with your study.
