Background • Who is Steve Ruberg? • How does pharma generate and utilize clinical Background • Who is Steve Ruberg? • How does pharma generate and utilize clinical data? • What is CDISC? • What has CDISC done, what are they doing, and what are they considering? • Where does CDISC need help?

Steve Ruberg • Statistician – Not IT, though much learning over last decade – Steve Ruberg • Statistician – Not IT, though much learning over last decade – Creator, recipient, analyzer, archiver, submitter of clinical data • Helped launch CDISC as not-for-profit in 2000 – First Chairman; just finished my term on the Board in Dec, 2007

Pharma Clinical Data Company executed trial • Getting data from investigators – Paper and Pharma Clinical Data Company executed trial • Getting data from investigators – Paper and electronic • Getting data from labs – Central vs local • Getting data from other sources – Growing variety of electronic data capture

Electronic Data Capture at an Investigator Site Electronic Data Capture at an Investigator Site

Pharma Clinical Data Other considerations • Working with a CRO – Defining data specs Pharma Clinical Data Other considerations • Working with a CRO – Defining data specs – Receiving datasets • Submissions to the FDA – Observed/raw data and derived/analysis data – Analysis programs, reports

Pharma Clinical Data Value of Standards • Operational efficiency – Reduce programming and re-mapping Pharma Clinical Data Value of Standards • Operational efficiency – Reduce programming and re-mapping of data – Increase automation; better tools • Scientific effectiveness – INTEGRATION OF DATA – Better analysis, interpretation, understanding • FDA remit: Promote and protect health

What is CDISC • CDISC is a global, open, multidisciplinary, non-profit organization that has What is CDISC • CDISC is a global, open, multidisciplinary, non-profit organization that has established standards to support the acquisition, exchange, submission and archive of clinical research data and metadata. The CDISC mission is to develop and support global, platformindependent data standards that enable information system interoperability to improve medical research and related areas of healthcare. CDISC standards are vendor-neutral, platform-independent and freely available via the CDISC website. • Established as a non-profit in 200 • Most members from pharma or companies (CROs, software vendors) that support pharma clinical research

What is CDISC Doing CDISC models – SDTM – Submission Data Tabulation Model (used What is CDISC Doing CDISC models – SDTM – Submission Data Tabulation Model (used for FDA submissions; can also be used for CRO submissions to pharma sponsor) • Defines structure (vertical) and some categorization/data domains and minimal terminology – ODM – Operational Data Model • XML messaging standard – LAB – Clinical laboratory data model

What is CDISC Doing CDISC models – SEND – Standard for Exchange of Non-clinical What is CDISC Doing CDISC models – SEND – Standard for Exchange of Non-clinical Data • Non-clinical version of SDTM • Used for FDA submissions; can also be used for CRO submissions to pharma sponsor • Defines structure (vertical) and some categorization/data domains and minimal terminology – ADa. M – Analysis Data Model • Suggested structures for FDA submission of analysis data – Protocol Representation Group • Terminology/data definitions to describe a protocol/study

What is CDISC Doing CDISC models – CDASH – Clinical Data Acquisition Standards Harmonization What is CDISC Doing CDISC models – CDASH – Clinical Data Acquisition Standards Harmonization • Non-clinical version of SDTM • Used for FDA submissions; can also be used for CRO submissions to pharma sponsor • Defines structure (vertical) and some categorization/data domains and minimal terminology – ADa. M – Analysis Data Model • Suggested formats for FDA submission of analysis datasets – Terminology • Creating more detailed data element specifications for use in SDTM

What is CDISC Doing • CDISC works in virtual teams – Conference calls, meetings What is CDISC Doing • CDISC works in virtual teams – Conference calls, meetings – Tends to focus on pieces (data domains like adverse events, demography, vitals signs, etc. ) of the clinical business • Progress, but slow and limited

What is CDISC Considering • CDISC models have some utility but cannot meet data What is CDISC Considering • CDISC models have some utility but cannot meet data integration needs – Not enough unambiguous data element definitions (i. e. terminology) – Caution: terminology means different things to different people • Concept • Valid value set

Proposal • WHAT • Build a comprehensive, industry-wide electronically accessible and consumable data element Proposal • WHAT • Build a comprehensive, industry-wide electronically accessible and consumable data element dictionary that contains the “clinical words” used in clinical research studies

 What Is a Data Element Definition? • All the pieces of information (i. What Is a Data Element Definition? • All the pieces of information (i. e. attributes) needed to unambiguously describe a concept • English dictionary analogy – – Word – desk Phonetic spelling – dĕsk Part of speech – noun Definition – a piece of furniture with a flat top for writing [could also be thought of as the concept] – Source – Latin, discus – etc.

Proposal • HOW - Business model • An open, electronic, peer production environment with Proposal • HOW - Business model • An open, electronic, peer production environment with appropriate governance (e. g. a wiki) • • • Like Med. DRA, but open and free Like Wikipedia, but more governance Like LINUX, but more granular and dynamic • We must adopt a more flexible and rapid development process to get this in place

Next Steps • CDISC is considering this need (data element dictionary) and seems to Next Steps • CDISC is considering this need (data element dictionary) and seems to be moving in this direction – Make your voice heard to CDISC if you see the value – Create a sense of urgency as you see fit • CDISC is considering the wiki approach – Let me and/or CDISC know of your willingness to contribute to a wiki – We could build this together much faster – Requires a new business model / approach • Can W 3 C give advice, input or help?
