CDASH Initiative: Status Update Bay Area CDISC Implementation Network Meeting - May 29, 2008 Rhonda Facile, Project Director, CDISC Dorothy B. Dorotheo, InterMune Mark Wheeldon, Formedix
Snapshot Overview • CDASH Purpose & Scope • Who Participated in CDASH • How CDASH Developed? • CDASH Domains – Where are we? • CDASH Domains – New Ideas • CDASH Variable Metadata • CDASH Core Designations • Practical Implementation of CDASH within CDISC ODM • CDASH Goals
Snapshot • Critical Path Opportunity #45 – Streamline data collection at investigative sites. • Continuation of ACRO’s Initiative • Started October 2006 • Supported by a Collaborative Group of 17 organizations • Core team of 15 members manages.. • 11 working groups • Groups with between 8-40 volunteers • ~190 work group volunteers + additional reviewers (both nationally and internationally) • 16 Safety data domains developed.. • organized in 4 “Packages” • Draft consolidated document now out for public review – April 2008
CDASH Purpose & Scope • To develop a set of ‘content standards’ (element name, definition, metadata) for a basic set of global industry-wide data collection fields that support clinical research. • The initial scope - ‘safety data/domains’. • These safety domains cut across all therapeutic areas (TA independent). • Follow CDISC Operating Procedure for Standards Development (COP-001).
Participants in the CDASH Initiative Other = Academic Research Organizations, Government (NIH, NCI), Hospitals, Universities. Who Participated in CDASH? • Team membership: • Statisticians • Medical Monitors/Clinical Scientists • Regulatory Affairs • Drug Safety • Data Managers • Clinical Study Coordinators • Clinical Research Associates • Investigators • Clinical Program Managers • Statistical Programmers • Database programmers • More multi-national input welcome.
How was CDASH Developed? • Start with Study Data Tabulated Model (SDTM) • Focus on CRF Content, not CRF Layout • Refer to ACRO CRF Samples (where available) • Collect CRF samples • Evaluate commonalities/differences of CRF samples • Document data points included/excluded with justifications
How was CDASH Developed? • Agree on basic data collection fields • Map to SDTM • Terminology - proposals shared with the Terminology Team • Write definitions and completion instructions for clinical site and Sponsors • Proceed to the next step in the Consensus Process

CDASH Variable Metadata Question text for collection on the CRF. How to implement the CRF data collection variable Describes the purpose of the data collection field Aka CRF Completion Instructions SDTM-IG conforming variable name (CDASH variables shaded) CDASH Core Designations
CDASH Core Designations • Highly Recommended A data collection field that should be on the CRF (e.g., a regulatory requirement (if applicable)). (e.g. Adverse Event Term) • Recommended/Conditional A data collection field that should be collected on the CRF for specific cases (may be recorded elsewhere in the CRF or from other data collection sources). (e.g. AE Start Time) • Optional A data collection field that is available for use if needed. (e.g. Were there any AE Experienced?)
“Practical Implementation of Clinical Data Acquisition Standards (CDASH) in the CDISC Operational Data Model” Mark Wheeldon, CEO, Formedix Bay Area User Group, 29th May, 2008
Who are we? • Involved with Standards since 2001 • All our solutions are based on Open CDISC Standards • CDISC Products and Consultancy Company • Planning, Preparation and Implementation CDISC Services • Products so you can use CDISC in house! • Product Focus is on Study Specification and Design Tools • Origin™ authoring tools to streamline Protocol to Submission Process • Database Specification uses CDISC Operational Data Model • Origin Study Modeller™ • Submission Specification uses CDISC Define.xml • Origin Submission Modeller™ • Must work with and around existing processes/technologies • Operational Data Model for EDC auto generation • Existing internal analysis and reporting structures • New or existing extract, transfer and load tools
How could CDASH be used today? • Use as a Content Standard • Off the shelf Case Report Form content • Describes relationship between Operational Data and Submission Datasets • CDASH represented within a proprietary file format • Excel, Word, Proprietary EDC system format • Potentially unstructured • Use within Machine Readable Metadata • CDASH represented in CDISC Operational Data Model • Vendor neutral system independent format • Hierarchical structure is ideal for re-usable library of Components
Benefits of using CDASH withinthe CDISC Models • Library Development • CDASH forms represented in CDISC Database Standard • Safety Domains in CDISC Submission Standard • Study Specification • Using CDISC metadata to reduce study set-up time • Automation of Electronic Data Capture Build • Using CDISC ODM to reduce study build times • Optimize Downstream Dataflow • Operational data to submission • Reduces mapping complexity • Makes mappings re-usable
What is CDASH?What is it Not? • Content Standard NOT a Model • Database Variable Name, Definition, Question Text • Instructions to the Site, SDTM Variable Mapping • Core Designations is a killer feature • Give clinical context on why something is collected • Highly Recommended, Recommended/Conditional, Optional • Clinical Perspective on data collection • What is it not? • One to one mapping with the SDTM • AEYN not in SDTM • AEBODSYS not in CDASH
ODM Building BlocksHow does CDASH Relate? Clinical Database Variable Name Controlled Terminology CDASH CRF Label/Question CDASH Core (Highly Recommended)
CDASH Adverse Event Form in ODMNo more hand building of this…

ConclusionsCDASH-ODM Delivers Today • Library Development • CDASH brings clinical perspective • CDASH links to SDTM to bring a submission perspective • Quickly settle disputes over content • Streamline Study Set-up and EDC Build Process • Eliminate manual study specification • Study Spec from 492 hrs down to 158 hrs (3x shorter) • 30-40% build time reductions • Downstream Raw Data to Submission Dataflow Optimisation • Consistency between Operational Data and Submitted Datasets • Reduction in mapping complexity – quick to create • Mappings easier to maintain
CDASH Goals • Finalize and Post CDASH final draft for public review • CDASH Roadshow & Training program. • Finalize and Post CDASH V. 1.0 on CDISC.org. • Develop and Publish CDASH-ODM metadata • Establish subgroup, Scope, Deliverables, Participants and Timelines • Identify and Collect feedback from “Early Implementers” • “CDASH” New SDTM Domains as required.
