Copyright © 2016 Intelent Inc. All rights reserved. Role of Dynamism and Automation in Integration Drivers for Dynamism and Automation Dynamism Automation Source structure, transformation rules, target structure based on study analytical needs. Most could vary across studies. This warrants a set of dynamic transformation rules to accommodate heterogeneous needs. In addition the structure of the source, the physical storage, maturity of the data transfer mechanism and relevant data dictionaries could vastly vary as well Important to minimize and possibly avoid any code change, transformation pre-processing services in data ingestion layer. These are simply costly and time consuming, and discourages adoption within the enterprise. Storage structures at appropriate levels of hierarchy and stages of data lifecycle need to be dynamic Such dynamism needs to be planned either by leveraging existing metadata or manufactured metadata Alternatively or in addition, a robust user interface or means of configuration can address gaps. Key is to minimize code change. High availability of data to points of analysis From disparate sources: Raw source data, integrated data across CTMS, IxRS, EDCs, Labs, Reconciled, cleansed/not cleansed, aggregated data Based on use cases - interim analysis, submission, operational metrics, central monitoring, medical monitoring etc. Key is to automate data delivery in appropriately usable format with minimal manual intervention

Integration – Two Approaches Warehouse ApproachIntegration AspectsHub Approach Storage and Modeling Source Data Integration Data Processing Pre-Modeling Required Structure oriented Generic content model (schema) required based on storage technology. For Ex. Form/Domain level storage No Pre-Modeling, Loosely coupled Storage granularity preserved as per the source system. Data tagged at appropriate level after reconciliation. Requires source system adapters, Pre formatting to warehouse structure – ETL approach. Enabling dynamism and automation for transformations, requires: Availability of a repository of governed metadata – structural and transformational. Interface that allows study level mappings and leveraging existing library of rules Multiple adapter development, especially with external sources (Labs/partner data) System agnostic Integration. Data is ingested at source level granularity without pre-processing – ELT approach. Requires source feeds to adhere to input descriptions or requires setup / configuration Robust mapping user Study level which utilizes a mapping library with auto (machine) learning technologies – promotes mapping reuse across studies Post processing pipeline architecture Heavy reliance on data pre-processing before loading into the warehouse Time consuming and costly Transformations accomplished on an as- needed basis, in a post-processing layer, based on business needs. For Ex: Operational review processes need subject level data granularity Bio-statistical programming processes need SDTM +/- domain level tabulated data

How do we adapt to changes in regulatory standards rapidly and apply these changes to business and operational processes? How do we bring in more efficiency in the source to target mapping and transformation processes? Data Ingestion Framework ingests data from Diverse Sources (clinical data, operational data, reference data) Populate Structural Metadata (Source/Target/Reference) and Transformational Metadata (rules/derivations) in Metadata Repository Dynamic Process applies transformation rules on source data to generate target datasets Solution Overview Solution Impact High Availability of Data (Source, Integrated, Standardized) Reusability of Standard Algorithms Dynamic Automated Process Accelerated Path for Submissions Enhanced Support for Product Defense, Data Sharing, Data Mining Traceability

Approach 1 - Metadata Driven Dynamic SAS Engine Structural & Transformational Metadata extracted from Metadata Repository drives dynamic program for generating hybrid SDTM target datasets Dynamic SAS process leverages SAS Macros corresponding to transformational metadata Source to Target Transformations – Updates in metadata repository applied in next run, MedDRA Merge, ISO Formats
