SAS is planning to provide additional CDISC capabilities via the SAS Clinical Data Standards toolkit and the SAS Clinical Data Integration product in 2009. The toolkit is initially focused on SDTM validation and define.xml creation, and, like Proc CDISC, will be available at no additional cost over a SAS/Base license.
