http://www.sas.com/industry/government/fda/faq.html FDA can accept data in the SAS XPORT Transport Format (Open Format) that is processed by the XPORT engine in Version 6 of SAS software and later, and by PROC XCOPY in Version 5.

An annotated case report form (CRF) is a blank CRF with annotations that document the location of the data with the corresponding names of the datasets and the names of those variables included in the submitted datasets.

Definition : The data definition file describes the format and content of the submitted datasets. (SDTM & ADaM) Specifications : The specification for the data definitions for datasets provided using the CDISC SDTM IG or SEND IG is included in the Case Report Tabulation Data Definition Specification (define.xml) developed by the CDISC define.xml Team. The latest release of the define.xml is available from the CDISC web site (http://www.cdisc.org/models/def/v1.0/index.html).http://www.cdisc.org/models/def/v1.0/index.html FDA can accept definition file in XML or PDF format.

FDA’s Enterprise Program to improve management of structured scientific data Clinical study data Nonclinical study data Pharmacogenomic (and other –omic) data Product quality and manufacturing data Post-market surveillance data What is Janus?
21
Severity Levels in Janus Validation Criteria Severity Levels in Janus Validation Criteria Severity Description High The error is serious and will prevent the study data from being loaded successfully into the Janus repository. The SDTM study will not be loaded into the Janus repository Medium The error may impact the reviewability of the submission, but will not have an impact on loading the study data into the Janus repository. The SDTM study will be loaded into the Janus repository Low The error may or may not impact the reviewability or the integrity of the submission but will not have an impact on loading the study data into the Janus repository. The SDTM study will be loaded into the Janus repository
22
Janus Validation Criteria Define.xml that fails the structural validation check or check for controlled vocabularies1 Missing mandatory domains—mandatory domains for Janus include DM (demographics), EX (exposures), and DS (disposition) Missing mandatory fields in either the mandatory domains or optional domains provided in the submission Date fields in the submission (all domains) are not compliant with the SDTM specification Domain-specific errors as described in the detailed specifications described below. http://www.fda.gov/ForIndustry/DataStandards/StudyDataStandards/ucm155327.htm

FDA request eCTD (CDISC) as a Submission -We don’t have another option!!! It is desired that taking a charge of SDTM conversion process by DM team is better than SAS Programming team according to our experience. - Prevent chance of manipulating raw data - Require to prevent SAS programmer’s own idea It is desired that applying CDISC at early stage of project - Lower Cost / Time - Increase SDTM Data Quality Janus is under developing
