C.7.1.3.1.2 Clinical Trial Protocol ID

The Clinical Trial Protocol ID (0012,0020) is the number or character sequence used by the Clinical Trial Sponsor to uniquely identify the investigational protocol in which the subject has been enrolled.

Note

If there is a need to record more than one identifier for the protocol, one may be conveyed Clinical Trial Protocol ID (0012,0020) in the top level dataset and the others included in Other Clinical Trial Protocol IDs Sequence (0012,0023), and the source of each distinguished by their Issuer of Clinical Trial Protocol ID (0012,0022).

Here is an example of identifying a completed trial whose data has been shared and assigned a digital object identifier:

  • Clinical Trial Protocol ID (0012,0020) = "TCGA-GBM"

  • Issuer of Clinical Trial Protocol ID (0012,0022) = "NCI"

  • Other Clinical Trial Protocol IDs Sequence (0012,0023)

    • >Clinical Trial Protocol ID (0012,0020) = "doi:10.7937/K9/TCIA.2016.RNYFUYE9"

    • >Issuer of Clinical Trial Protocol ID (0012,0022) = "DOI"

Here is an example of identifying a clinical trial that is potentially ongoing and not yet published or shared, and has multiple (primary and secondary) identifiers from the same issuer (which are enumerated but not otherwise distinguished from each other):

  • Clinical Trial Protocol ID (0012,0020) = "D6940C00002"

  • Issuer of Clinical Trial Protocol ID (0012,0022) = "NCI"

  • Other Clinical Trial Protocol IDs Sequence (0012,0023)

    • >Clinical Trial Protocol ID (0012,0020) = "NCI-2018-00805"

    • >Issuer of Clinical Trial Protocol ID (0012,0022) = "NCI"

    • >Clinical Trial Protocol ID (0012,0020) = "135803"

    • >Issuer of Clinical Trial Protocol ID (0012,0022) = "NCI"

    • >Clinical Trial Protocol ID (0012,0020) = "2017-002451-28"

    • >Issuer of Clinical Trial Protocol ID (0012,0022) = "NCI"

    • >Clinical Trial Protocol ID (0012,0020) = "NCT03423628"

    • >Issuer of Clinical Trial Protocol ID (0012,0022) = "ClinicalTrials.gov"
