Registration Procedures and CTSU Website Access
Access to the CTSU members’ website allows users at clinical institutions participating on NCI-supported trials to view several resources including:
  • Protocol and protocol-related documents
  • Funding information for studies under the NCI National Clinical Trials Network (NCTN)
  • NCI Central Institutional Review Board (CIRB) documents for sites participating in the CIRB initiative
  • Links to Medidata Rave® and the Oncology Patient Enrollment Network (OPEN)
  • Access to the Data Quality Portal, Site Audit Portal, and accrual information
  • Information on regulatory submissions
  • Educational materials
  • E-mail notification on protocol updates and CTSU-supported activities  
Access is managed through the Cancer Therapy Evaluation Program - Identity and Access Management (CTEP-IAM) registration system. A valid user name and password from IAM is required for access to the CTSU website. Registration in the Registration and Credentialing Repository (RCR), a self-service online person registration application with electronic signature and document submission capability, is also necessary for most users. The RCR recognizes five types of registered users:
  • Investigators (IVR) – licensed MD, DO, or equivalent.
  • Non-Physician Investigators (NPIVR) - advanced practice clinical staff who may act as study principal investigators (PI), site-protocol PIs, or enrolling PIs in OPEN for select studies.
  • Associate Plus (AP) – clinical site staff integral to the conduct of NCI-supported studies.
  • Associate (A) – other clinical or administrative staff that require access to NCI-supported applications but act in a supporting role (ordering designees, regulatory submissions, etc.).
  • Associate Basic (AB) – individuals that require limited access to select NCI-supported applications or are tracked for administrative purposes (i.e., industry contacts). ABs will not have access to the CTSU website.

Food and Drug Administration (FDA) regulations and National Cancer Institute (NCI) policy require all investigators (IVRs and NPIVRs) participating in any NCI-sponsored clinical trial to register and to renew their registration annually.

Investigator registration will be completed in the RCR and requires electronic submission of:

  • FDA Form 1572 or International Investigator Statement
  • Financial Disclosure Form
  • NCI Biosketch
  • Agent Shipment Form (if applicable)
  • Human Subjects Protection
  • Good Clinical Practices
  • Optional Curriculum Vitae (CV)

APs must complete an annual registration in RCR and electronically submit a Financial Disclosure Form, NCI Biosketch, Human Subjects Protection, Good Clinical Practice, and Optional CV.

Associates and ABs will perform annual registration using IAM. Associates may access the CTSU website and systems including view access to OPEN and Rave. ABs may not access the CTSU website or systems.
