Service Description

The Trial Registration Service provides a standardized set of interfaces for registering Trials with NCI's Clinical Trials Reporting Program (CTRP). There are two main categories of clinical trials that can be registered with CTRP - NCI-supported trials (also referred to as Complete trials) and Industry-led (referred to as Abbreviated Trials). Please visit to learn more about NCI's CTRP.

The Trial registration service's semantic representation leverages the computable structured representation of a Study Protocol as defined by the BRIDG model and implemented in COPPA services as a BRIDG based Information model in support of computable semantic interoperability.


Obtain a valid user account for CTRP for the environment (Integration, Demo, Stage, or Production) that you intend to use.
