CDISC Migration

Study Data Tabulation Model (SDTM) and Analysis data Model (ADaM) are two standard structures set by the Clinical Data Interchange Standards Consortium (CDISC). These standard structures are to be adhered to during data submission of human clinical studies to regulatory authorities like the United States Food and Drug Administration (FDA). This transformation of raw data of a clinical study to CDISC standards is referred to as CDISC Migration.

Kreara has an expert team of professionals with sound knowledge in these standard structures, corresponding implementation guides, CDISC terminologies and the related ICH guidelines. The team keeps track of the latest developments and changes by subscribing to newsletters, actively participating in discussion forums and attending conferences.

As part of CDISC migration, the team develops the specification document and the annotated Case Report Form (CRF), which present the mapping of variables from raw database to the CDISC standards. The team also develops SAS programs which actually map the data from the raw structure to the standard structure and the SAS datasets containing data as per CDISC standards.
