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.
