Executive Summary

Company Leading contract research organization (CRO)

Contract research organizations (CROs) submit electronic data capture (EDC) data to many pharmaceutical sponsors. Each sponsor generally imposes differing data requirements, distracting CROs from their core business mission.

Industry Life Sciences Liaison Solution ALLOY Health™

One such CRO engaged Liaison to shield it from this distraction and its attendant complexities. As a result, Liaison implemented a fully managed solution on its ALLOY Health™ cloud platform that collects data in native form from the CRO, transforms the data into various sponsor-required formats, and delivers the data via sponsor-preferred communications protocols—securely and in real time. This allows our CRO client to meet the varying needs of its sponsors and, just as important, provides its sponsors with timely, high-quality data in a compliant manner.

Challenges: Lack of Agility and Resource Scaling for Current Custom-built Solution Prior to turning to Liaison, the CRO client maintained a custom inhouse EDC solution to meet the requirements of its sponsors. Over time, and as new sponsor requirements were added, the implications for compliance, performance, operations, support and maintenance, coupled with a scarcity of resources, made it prohibitive for the CRO to continue down this path. Some of the key sponsor requirements were: •

Provide EDC data in CDISC LAB data model format

To support subsequent analysis by sponsors, the data had to conform to strict data quality requirements

Incremental feeds, which required CRO to ‘chunk’ its cumulative EDC system feed into incremental ones

Uploading of incremental data feeds in real time, through services exposed by sponsors’ data ingest platforms, without manual intervention

Solution: ALLOY Health, Delivered as Managed Services, Buffers Complexities Liaison buffered the inherent complexities of conforming to varying sponsor-specific data and delivery requirements by developing a solution that allows the CRO to hand off its EDC data in native form. The native data is processed and validated between the CRO and Liaison through the one-time implementation of a standard canonical. Liaison then takes the validated canonical data and transforms it into sponsor-specific formats. This approach enables reuse of the core data processing logic from one sponsor to another by implementing it on top of the canonical. Additionally, the Liaison Enterprise Navigation System (LENS) provides the CRO with end-to-end visibility across this data flow so that status and outcome can be verified. Liaison’s managed services model, which consists of a combination of technology, processes, and people, further met the needs of our CRO client by protecting highly skilled resources from the operational aspects of the solution.
