TSPARM "Pharmacological Class" Terminology Change

Short Name
TSPARM "Pharmacological Class" Terminology Change
Affected Standard
SDTMIG v3.1.3
SDTMIG v3.2
Description of Codelist Change

The SDTMIG, in an appendix and in a Trial Summary (TS) Example, "NDF-RT" is given as the terminology to be used for TSVAL when TSPARMCD = "PCLAS".

"NDF-RT" stands for "National Drug File - Reference Terminology", It has been replaced by "MED-RT" or "Medication Reference Terminology" as explained here https://evs.nci.nih.gov/ftp1/MED-RT/Introduction%20to%20MED-RT.pdf .

The FDA Data Standards Catalog, 2018-12-19 and later versions, specified "MED-RT" as the terminology to be used for TSVAL when TSPARMCD = "PCLAS".

Standard with Codelist Change

The codelist was corrected in SDTMIG v3.3.


Affected Variable Codelist in Published Standard Replacement Codelist
TS.TSVAL when TS.TSPARMCD = "PCLAS"
NDF-RT
MED-RT

Impact of Issue Coping Strategy

For data that has not been coded, the NDF-RT codelist is no longer available.

Use the MED-RT codelist instead.

Data values taken from the NDF-RT codelist may not be present in the MED-RF codelist.

Most code values are probably the same, but should be checked.
