The Clinical Trials Monitoring Service (CTMS)/Theradex will be available starting at 2 PM ET on Wednesday, 2/24/21. At that time you will be able to use OPEN for slot reservations and patient enrollments for ETCTN, CTMS monitored CITN and CCR studies and protocols NCICOVID, 10231, and 10323. Please hold enrollments for these trials until 2PM. OPEN will be updated with the patient ID and treatment assignment for those patients that were enrolled manually during the outage. CTSU will reach out to sites with instructions if further action is needed by the sites. Please do not attempt to re-enroll any patients unless instructed to do so. If you do not see your enrollment in the ‘in progress’ screen in OPEN, please contact the CTSU Help Desk – do not recreate a new enrollment.

Welcome to the Oncology Patient Enrollment Network (OPEN) Portal system

OPEN is the web-based registration system for patient enrollments onto NCI-sponsored Network Group clinical trials. The system is integrated with the CTSU Enterprise System for regulatory and roster data, and with each of the Network Groups' registration/randomization systems for patient registration/ randomization. OPEN provides the ability to enroll patients on a 24/7 basis.
