It is the responsibility of the Principal Investigator to ensure that registration, results reporting, and updating are performed within the specific timelines required by each applicable rule body for all new and ongoing clinical trials.

The Principal Investigator or designee is responsible for performing the following functions:

  • Identify studies requiring registry in a publically accessible database;
  • Request user account set-up within UNC organization account;
  • Create records on;
  • Confirm accuracy of record content;
  • Change Record Status following edit completion to trigger release process;
  • Ensure notification emails are addressed within 15- and 25-day timelines (registration and results records, respectively);
  • Maintain records on in accordance with all regulatory and policy driven requirements;
  • Notify the Office of Clinical Trials of receipt of any correspondence from an external agency regarding Final Rule (42 CFR Part 11) requirements, NIH policy requirements, record: registration, results, and/or record maintenance requirements;
  • Notify the Office of Clinical Trials within 30 days of an expected and 15 days following an unexpected Principal Investigator/Responsible Party personnel change. All changes in Study Official (Principal Investigator), their official title, and/or contact information must be updated in the record within 30 days of the change.

The Office of Clinical Trials offers support, guidance, and assistance including user account set-up, record creation; record maintenance/updates, and results reporting.

Incoming new faculty or leaving faculty may need to transfer records into or away from the University with them. The Office of Clinical Trials can assist with this as well.

Depending on the reason for registering and associated requirements, Records consist of 1-3 sections: Protocol (initial registration record), Results, and Document Sections. The Protocol (initial registration) is the minimum registration requirement for those studies being registered to meet ICMJE and CMS rules. While permissible to enter results for such trials, it is not required. Records registered to meet Final Rule and/or NIH Policy requirements, must report results within no later than 12 months of reaching the “Actual” Primary Completion. These studies must add and complete a results record and upload a protocol in Portable Document Format Archival (PDF/A) format. If the Statistical Analysis Plan (SAP) is included within the protocol, the protocol including SAP is the only item required for upload. However, if a stand-alone SAP exists, then it must be uploaded too. Each document must include a cover sheet indicating the Official Study Title, NCT number, and date of document.

The process for registering individual studies at is described below. This pertains only to investigator-initiated studies.

  • A study must have been submitted to an IRB for review prior to registry although actual approval is not required prior to protocol record creation.

UNC’s IRB does not review the data registered for a given trial. Ultimate responsibility for record accuracy lies with the Principal Investigator (PI) although a preliminary quality control (QC) review is performed by UNC’s account administrator before release to where a separate QC review is conducted.

An individual user account must be established at by the University Administrator for the study Principal Investigator (PI) and all designees requiring record access as user accounts should not be shared among users. To request a user account, send an e-mail to or providing the user’s name, department, telephone number, and e-mail address. The user account will be created within the same day if at all possible, and usually within minutes of account set-up, the new user will receive an e-mail from providing the login details and a temporary password.

The PI or the PI’s designee will complete the required record fields by entering study-specific details into the website. The Protocol Registration Data Element Definitions for Interventional and Observational Studies definitions document is available from the Help ‘pull-down’ menu on the Home page upon log in and is also accessible by using the ‘Definitions’ hyperlink found in each edit module. This document includes all of the registration recordʼs field definitions and can be used to identify which fields are (*) required, () required if Study Start Date is on or after January 18, 2017, or ([*]) conditionally required.

When creating a new record, enter the 6-digit, hyphenated, IRB number (i.e., XX-XXXX) into the first entry field as the “Unique Protocol ID” since UNC has no overall protocol numbering convention. For those using a department or other protocol identifier, this can be entered into the Secondary ID field (found within the Study Identification section).

Unreleased records cannot be seen outside the University’s PRS account. Records must progress from “In Progress” to “Entry Complete” to “Approved” and then to “Released” in order to be reviewed by staff and updated on the public website. This applies to initial record creation and subsequent record updates (e.g., after making edits based on review comments or any future registration or results record updates).

Once editing is complete and the Record Status is changed from “In Progress” to “Entry Complete,” an automated system e-mail is sent to the University Administrator (Office of Clinical Trials) advising that the record is ready to review and edit (or facilitate editing), if necessary. Upon review completion, the administrator will then approve and release the record for review by Until this release occurs, no one outside of UNC can see the record (new registrations) or updated information (existing record edits). Once released, will perform a system validation and QC review. For protocol records this usually occurs within 2 to 5 days of release. For records containing results, each review may take 30 or more days.

If identifies questions or requests additional information/clarification, they will send notification via email to the Record Owner (for registration records) or Results Point of Contact (for records with results) which contains instructions for accessing comments within the record. To remain compliant, records must be edited to address issues identified by notification within 15 calendar days for protocol/registration records and within 25 calendar days for records with results. Upon completion of their review, will assign an NCT number and publically post the new registration record, record maintenance updates, or results record.

In order to qualify for publication consideration, enrollment should not begin until the NCT number assignment is received as studies are not officially considered to be registered until the NCT number is received. The NCT number is not provided until the QC review process has been completed. Please allow adequate time this process.

Results must be entered for studies that fall under the Final Rule and/or NIH Policy requirements no later than 12 months after the “Actual” Primary Completion. The Primary Completion date is defined as the date of final data collection for the primary outcome measure(s). The results record can be created once an “Actual date has been entered into the Primary Completion date field within the protocol record. Much of the results record is constructed using information within the protocol record, especially the outcome measures which will be pulled into the results record to become the labels for the data reporting tables. Prior to creating the results record, ensure that the protocol section is accurate especially the outcome measure titles, descriptions, and time frames such that these will be meaningful to people who are unfamiliar with the study. Narrative conclusions are not allowed within the results record. A results record is comprised of: Participant Flow, Baseline Characteristics, all primary and secondary Outcome Measures as specified in the statistical analysis plan, Adverse Events (by treatment), and a copy of the IRB-approved study protocol as well as the statistical analysis plan if existing as a separate document. Please see the Help: Results Data Entry section for templates, checklists, and other instructional information related to results reporting.

Results entry examples for common designs: Parallel; Crossover; Multiple Period; Factorial; and Dose Escalation.

Additional registration and results reporting tools provided by are available by clicking the ‘Help’ menu on the PRS homepage to better understand, prepare, and organize registration and results reporting. Included there are results data preparation checklists and simple results templates and examples.
