Trials are conducted in participating sites. You must provide information about the site itself (organization), the investigator(s), and primary contacts (if a central contact is not provided). Optionally, you can include contact information for a person’s title (functional role) rather than a person’s name. When you add a participating site to a trial, link (associate) an organization, site, investigator(s), and primary site contact information to it.

Providing a site contact is optional if you provide a central contact instead.

The system assigns investigators and primary contacts a status code that corresponds to the person’s/role’s curation status.

Information about participating sites can be included in the protocol document or in the Participating Sites document.

How to Abstract Participating Site Information 

  1. Search for the trial of interest. For instructions, refer to Searching for Trials in PA.

  2. In the search results, click the NCI Trial Identifier link for that trial. The Trial Identification page appears.

  3. On the Trial Identification page, check out the trial. For instructions, refer to Checking In and Checking Out Trials. (This checkout step is optional for Super Abstractors.)

  4. On the Administrative Data menu, click Participating Sites. The Participating Sites page appears.

  5. Click Add.

    The Participating Sites page displays three tabbed sections: Participating Site, Investigators, and Contact. The Participating Site tab is displayed by default.

    You must abstract the Participating Site information in the order indicated by the tabbed pages.

  6. On the Participating Site tab, in the various fields, specify the appropriate information. The following table describes the fields. An asterisk (*) indicates a required field.

    Field Label

    For Complete Trials (C)
    For Abbreviated Trials (A)

    Description/Instructions

    Organization Name*

    C, A

    Click Look Up and follow the instructions in Searching for Organizations. For Complete trials, the City, State, Country, and Zip/Postal Codes fields are populated with the organization information you selected.

    2. Select the status from the drop-down list. For valid ClinicalTrials.gov recruitment values, refer to Trial Status Values in the CTRP and ClinicalTrials.gov and Expanded Access Statuses.

    The system validates all status transitions when you save a trial status record. If you add or update a status transition that does not conform to the rules provided in Trial Status Transitions, the system displays errors and/or warnings. Warnings indicate that fixing the status record is optional; you do not have to resolve the transitions. However, Errors indicate that you must resolve the transitions by correcting trial status records in the  Participating Sites Status History window. You can not check in the trial until you correct all status transition errors. For a comprehensive matrix of valid transitions, see Trial and Participating Sites Status Transition Rules

You can not provide both types of contacts in the same record.


    If you designated a primary investigator as the primary contact (on the Investigators tab), the investigator's name is displayed automatically on the Contact tab.
