The story I am about to tell is almost 8 years old. I was managing software services delivery for a global pharmaceutical company from India. This was a very strategic account and the breadth of services covered diverse systems and geographies. It is very common that staff from the customer organization visit our delivery centers (offsite locations) to perform process audits, governance reviews and to meet people in their extended organizations.
During one such visit a senior executive noticed that two of my colleagues, sitting next to each other, supported their system (two different implementations of the same software) across two different geographies. They happened to have the name of the systems they support, pinned to a board at their desks. The executive wanted us to take a picture of the two cubicles and email to him. We were quite surprised at the request. Before moving on to speak to other people he asked a couple of questions and realized the guys were sharing each other’s experiences and leveraging the lessons learnt from one deployment for the other geography. It turned out that this does not happen in their organization, in fact their internal teams hardly communicate as they are part of different business units and geographies.
The story demonstrates how these organizations could become siloes due to distributed, outsourced and localized teams. Information Integration has become the way of life to connect numerous silos that are created in the process. Clinical research is a complex world. While the players are limited, depending on the size of the organization and the distributed nature of the teams (including third parties), information silos and with that the complexity of integration of data increases. The result is very long cycle times from data “Capture” to “Submission”.
Clinical Data Integration Challenges
The challenges in integrating the clinical data sources are many. I will try to highlight some of the key ones here:
- Study Data is Unique: depending on the complexity of the protocol, the design of the study, the data collected varies. This makes it difficult to create a standardized integration of data coming in from multiple sources.
- Semantic Context: while the data collected could be similar, unless the context is understood, it is very hard to integrate the data, meaningfully. Hence, the integration process becomes complex as the semantics become a major part of the integration process.
- Regulations and Compliance: Given the risks associated with clinical research, it is assumed that every phase of the data life should be auditable. This makes it very difficult to manage some of the integrations as it may involve complex transformations along the way.
- Disparate Systems: IT systems used by sponsors, CROs and other parties could be different. This calls for extensive integration exercise, leading to large projects and in turn huge budgets.
- Diverse Systems: IT systems used at each phase of the clinical data life cycle are different. This makes sense as the systems are usually meant to fulfill a specific business need. Even the functional organizations within a business unit will be organized to focus on a specific area of expertise. More often than not, these systems could be a combination of home grown and commercial off the shelf products from multiple vendors. Hence, the complexity of integrations increases.
What is Integration on the Cloud?
As mentioned earlier, integration is a complex process. As the cloud adoption increases, the data may be distributed across Public, Private (Includes On-Premise applications) and Hybrid clouds. The primary objective of integration on the cloud is to provide a software-as-a-service on the cloud to integrate diverse systems. This follows the same pattern as any other cloud services and delivers similar set of benefits as other cloud offerings.
The “Integration on Cloud” vendors typically offer three types of services:
- Out-of-Box Integrations: The vendor has pre-built some point-to-point integrations between some of the most used enterprise software systems in the market (like ERPs, CRMS etc.)
- Do-it-Yourself: The users have the freedom to design, build and operate their own integration process and orchestrations. The service provider may provide some professional services to support the users during the process.
- Managed Services: the vendor provides end-to-end development and support services
From a system design and architecture perspective, the vendors typically provide a web application to define the integration touch points and orchestrate the workflow that mimics a typical Extract-Transform-Load (ETL) process. It will have all the necessary plumbing required to ensure that the process defined is successfully executed.
Who are the players?
I thought it would be useful to look at some of the early movers in this space. The following is a list (not exhaustive and in no particular order, of course) of “Integration on Cloud” providers:
- Dell Boomi : Atom Sphere
- Informatica : Informatica CLOUD
- IBM : Cast Iron Cloud Integration
- Jitterbit : Enterprise Cloud Edition
These vendors have specific solution and service offerings. Most of them provide some out-of-the-box point-to-point integration of enterprise applications like ERPs, CRMs etc. They also offer custom integrations to accomplish data migration, data synchronization, data replication etc. One key aspect to look for is “Standards based Integration”. I will explain why that is important from a clinical data integration perspective later. While this offering is still in its infancy, there are some customers that use these services and some that are in the process of setting up some more.
Clinical Data Integration on Cloud
Many of you dealing with Clinical Data Integration may be wondering as to “Why bother with Integration on the Cloud?” while we have enough troubles in finding a viable solution in a much simpler environment. I have been either trying to create solutions and services to meet this requirement or trying to sell partner solutions to meet this requirement for the past 4 years. I will confess that it has been a challenge, not just for me but for the customers too. There are many reasons like, need to streamline the Clinical Data Life Cycle, Data Management Processes, retiring existing systems, bringing in new systems, organizational change etc. Not to mention the cost associated with it.
So, why do we need integration on the cloud? I firmly believe that if a solution provides the features and benefits listed below, the customers will be more than willing to give it a strong consideration (“If you build it, they will come”). As with all useful ideas in the past, this too will be adopted. So, what are the features that would make Clinical Data Integration on the cloud palatable? The following are a few, but key ones:
- Configurable: Uniqueness of the studies makes every new data set coming in from partners unique. The semantics is also one of the key to integration. Hence, a system that makes it easier to configure the integrations, for literally every study, will be required.
- Standards: The key to solving integration problems (across systems or organizations), is reliance on standards. The standards proposed, and widely accepted by the industry (by bodies like CDISC, HL7 etc.) will reduce the complexity. Hence, the messaging across the touch points for integration on the cloud should rely heavily on standards.
- Regulatory Compliance and GCP: As highlighted earlier, Clinical Research is a highly regulated environment. Hence, compliance with regulations like 21 CFR Part 11 as well as adherence to Good Clinical Practices is a mandatory requirement.
- Authentication and Information Security: This would be one of key concerns from all the parties involved. Any compromise on this would not only mean loss of billions of dollars but also adverse impact on patients that could potentially benefit from the product being developed. Even PII data could be compromised, which will not be unacceptable
- Cost: Given the economically lean period for the pharma industry due to patent expiries and macro-economic situation, this would be a key factor in the decision making process. While the cloud service will inherently convert CapEx to OpEx and thus makes it more predictable, there will be pressure to keep the costs low for add-on services like “new study data” integration.
All in all, I would say that it is possible, technically and economically and also a step in the right direction to overcome some existing challenges. Will it happen tomorrow or in the next 1 year? My answer would be NO. In 2 to 3 years, probably YES. The key to making it happen is to try it on the cloud rather than on-premise. Some of the vendors offering Integration on Cloud could be made partners and solve this age old problem.

Generic Industry Challenges:
Expiring patents, drying pipelines, increasing budgets, stringent regulations and cost pressures are some of the challenges faced by the Life Sciences industry. While these are macro challenges, teams responsible for clinical, regulatory and safety for clinical trials, regulatory submissions and patient safety respectively have a totally different set of challenges that they deal on a regular basis.
Data and documents generated during the course of the trials are managed by IT systems that have been either built in house or procured off the shelf. A major challenge that is faced by IT teams in large enterprises is to provide information and intelligence to their business teams that would cross (by integrating information) these siloes and help them make sound business decisions.
SOA based Information Integration:
Imagine a situation where all these systems in the clinical enterprise are integrated and connect seamlessly. The glue that binds all these systems can be a fully Service Oriented Enterprise Service Bus (ESB). Not just that, it should also be standards based. This will reduce the dependency on interfaces between systems in use and future proof the enterprise from replacement, retirement and enhancements to the individual systems. In order to bring visibility to data and documents across the systems there is a need to aggregate data and documents into Clinical Data Repository (CDR) and an Enterprise Electronic Document Management System (EEDMS).
The diagram above depicts a few information systems within the Clinical, Regulatory and Safety areas of Life Sciences R&D. This integration has to be:
- Loosely Coupled (SOA)
- Standards Based (CDISC / HL7)
- Open Architecture (XML, SOAP) and
- Survive system upgrades, replacements and retirements
Some of the advantages with the above mentioned integration would be:
- Integrated Clinical Enterprise Information Systems
- Easier and simpler integrations with partners and third parties
- Adoption of standards
- Integrated data and documents to enable faster decision making
- Faster Time to Market
- Lower Total Cost of Ownership and
- Better ROI
