CD12 - Implementing metadata standards at the protocol level
24 December 2018 I would like to begin my presentation with a little analogy. Maybe you remember this from your high school science class – this fire triangle- the idea behind it is quite simple – you just need the combination of air, fuel and heat to create fire, but without one of these key factors – you will not create fire… Imagine the fire triangle – require three essential elements to create fire – air, heat and fuel.

Standard Technology Process
CD12 - Implementing metadata standards at the protocol level 24 December 2018 Standard Technology Process Similar to the fire triangle – in order to implement standards, you need to establish 3 essential elements must be implemented, standards, technology, process. And without one of these factors – it will be difficult to successfully implement standards

The standards and technology at NN
CD12 - Implementing metadata standards at the protocol level The standards and technology at NN 24 December 2018 Protocol Standards CRF Standards CRF CRF CRF Submission Standard Date: / / Abc: x: y: Qwr: CDISC SDTM Data Domain: PE <XML> .… CDISC ADaM Data Domain: ADPE <XML> .… Standard DCM/DVGs CDW Numeric Findings Categoric Findings Subject Events (AE/Hypo/x) Interventions Visits Elements OC Table Responses Std. EOT XXCgfg hghj dklædfjkll sdfkf jklsd Xxxx Xxx Xxxx I will not spend too much time with this slide – I have included it makinly to give a big picture of the standards and systems we use at NN and how they are linked. We have standards within each area – protocol, CRF.. Etc. and we have worked to align with standards within the systems/areas. Howwever the main focus of this presentation is protocol metadata standards and how we have implemented metadata standards at the protocol level to support CDW and the standard terminology used in CRFs. At NN we have standards within the following areas – protocol standards, CRF standards, DCM/DVG standards – etc. We have systems to support these standards – protocol standards feed into CDW and CRFs – CRF standards feed into OC – standard DCMS. CDW – Clinical Data Warehouse, supports generation of standard outputs and standard submissions. Since the standards created at the beginning a trial wil inevitably affect the standards used at the end – we have work to align the protocol standards with what is in CDW. The motivation for doing this is because the standards used in the protocol will impact those used in the CRF and continue through to data collection chain. Therefore it’s best to implement these standards at the protocol level. The focus of the presentation is HOW we’ve done this at NN. We have worked to align standards across these areas. Mapping rules Standard Reports Standard Mappings Standard Code Values

The process supporting standards and technology at NN
CD12 - Implementing metadata standards at the protocol level 24 December 2018 The process supporting standards and technology at NN Trial Management Data Management Programmers and Statisticians Process – about the people involved – trial manager are setting the standards on the protocol level – using the PMT, data management has used CRF/OC to set standards and programmers and stat have been in stat standards. In the past and currently with CDW – there is a relatively dialogue between DM and stat – both are focused on standards and aware of CDISC. More of a challenge to create and implement standards and develop more a of process between trial management and stat. Can argue that the processes within stats have been refined around the new system. The processes between DM and stats have also been affected – primarily because OC set-up and mapping is essential for CDW to work. Furthermore DM is already focused on standardisation, particularly CDISC standards

PMT technology Protocol Metadata Template (Excel) Inexpensive
Easy to use Easy to modify Familiar to everyone At NN – we have created an Excel based tool – Protocol Metadata Template – to align and support the standards used in CDW with those used in the protocol. There are standard templates for Visit tructure, description of TD, TD diagram, TP, Dosage, TF – each template has a series of drop down menues from which standard terms can be selected. The structure of the templates and the terminology used is aligned with CDW – which in turn is very much aligned with CDISC terminology. A little history: the origninal intention of CDW was that it could be used by TM as well to enter protocol metadata – this was descoped and consequently a tool with Excel was created instead. You could argue that it was actually a benefit to use Excel because it is easy to modify (we’ve had several updates) minimal training, already familiar to endusers. Furthermore, CDW is a complex system, which we are still upgrading and perfecting – therefore it The downside of Excel is that it is not a validated system – cannot transfer the information directly from excel to CDW. Set backs with using excel: not a verified system so you cannot directly transfer the data from excel to CDW – data must be manually re-entered into CDW.

Title – free text Objectives – free text End-points – free text Visit structure – template – mix of drop down menus and free. Helps to ensure that visits are described consistently and always in relation to time point 0 – aids analysis at a later point. Description of trial design – code lists to select from to describe trial Trial design diagram – template Trial products – template Dosage - template Trial flow chart – template Sampling profile – template Functionalities – Word document – verified and can be filed with the protocol. Update the codelist from a master file – constantly updated

Protocol Metadata Template standards
CD12 - Implementing metadata standards at the protocol level 24 December 2018 WBC Leucocytes White Blood Cells Protocol Metadata Template standards Code sheet in CDW which contains a list of terminolgy used in the PMT, which is aligned with CDW. With the prefered term, for example leucocytes, there is also a list of synonyms. In the past protocols were created with the investigated in mind and prefered terms were selected based on what’s appropriate for the investigator – now prefered terms are aligned with CDISC and it is possible to include a synonym if needed. PMT standards group which maintains this list and evaluates requests for new standards – keeping in mind CRF, OC and CDw standaards. Somehow create a way for CDWs clinical and trial metadata to be used throughout protocols – this will influence which standards are used in the CRF – OC – CDW- Stat progs and analysis -> based on CDSIC terminology
9
Example of trial flow chart – they use drop menus to select the needed code.
10
Visit structure – drop down menus to describe visits – aligned with CDW. Ensures that visits are described in a common way throughout all protocols
11
The trial design diagram is aligned with CDW trial design and supports the development of generic trial designs. Primarily making it possible to quickly grasp the design of a trial, compare designs of different trials, seach within the data warehouse Purpose is to support reviewer to: Clearly and quickly grasp the design of a clinical trial Compare the designs of different trials Search a data warehouse for clinical trials with certain features Compare planned and actual treatments and visits for subjects in a clinical trial (future) Add to sat programming
