This section provides instructions for registering, updating, and amending Complete and Abbreviated trials via the NCI CTRP Trial Registration REST Service.
Introduction
Trial Registration REST Service is a CTRP Web Service that provides the following operations in a REST-like fashion:
- Register an Abbreviated trial in CTRP from ClinicalTrials.gov using a ClinicalTrials.gov Trial Identifier
- Update an Abbreviated trial in CTRP
- Register a Complete interventional or non-interventional trial in CTRP
- Update a Complete trial in CTRP
- Amend a Complete trial in CTRP
The service uses XML for data exchange.
Program Codes
The program codes feature (not to be confused with NCI Division and Program Values) has been enhanced. The system ignores program codes unless the trial is one of the following:
- Complete trial with a lead organization as a member of your cancer center family of organizations.
- Abbreviated trial where such a member is a participant.
The system validates program code values against those listed on the Manage Program Codes Master List page for your affiliated cancer center. For details, refer to Managing Program Codes.
Service Endpoints
Inside the NIH Firewall (VPN required)
Outside of the NIH Firewall
Access Requirements
To use the service, you must have a valid NCI LDAP account and a CTRP account. For instructions, refer to Creating New NCI CTRP User Accounts. All service endpoints require HTTP Basic authentication with your NCI LDAP username and password.
XML Schema
The service uses XML for data exchange. All XML elements going in or out of the service are defined and validated against the following XML schemas:
XML schemas are well-annotated with inline documentation that explains the purpose and meaning of various elements, types, and attributes. These schemas specify which elements are required and the required order of those elements. Specific elements required for service operations are explained in the sections below.
Persons and Organizations - Requirements and Recommendations
Registering or amending Complete trials in the CTRP involves organizations and persons that have the following roles in clinical trials: lead organization, sponsor, principal investigator, and so on. Use person identifiers (PO IDs) and organization identifiers (CTEP IDs) when you register a trial whenever possible. If they do not already exist, request that they be created prior to trial registration, by submitting a request to the CTRO at ncictro@mail.nih.gov
