The Pistoia Alliance Controlled Substance Compliance Services Project Successfully Passes the First Phase of Industry Testing

news · 7 years ago
London, United Kingdom, March 11, 2014 - Controlled Substance legislation is complex and ever changing. As such, it requires on-going and detailed interpretation to identify those compounds that are within scope of regional and international laws. The objective of the Pistoia Alliance Controlled Substance Compliance Service (CSCS) project was to facilitate development of commercial IT solutions to overcome this major compliance challenge.
Using a shared-risk funding model allowed technology suppliers and Pharma and other Life Sciences R&D organisations to work closely together to develop bespoke software tools while minimising financial risk. With multiple Pharma and other Life Sciences R&D organisations buying into a similar solution, there is the potential to reach a standardised interpretation of the controlled substance legislation across the industry.
The CSCS project is nearing completion, with the delivery of two independent, novel CSCS systems planned for early 2014.
The CSCS project team has successfully concluded a unique trial, demonstrating that these expert cheminformatics systems can predict to a high degree of accuracy if a chemical structure is classified as a controlled substance. Using Markush searching, combined with a dataset of known controlled substances, this trial tested against a comprehensive set of structures and legislation from three different countries.
Both ChemAxon/Patcore (a vendor consortium) and Scitegrity are making excellent progress with the development of their Controlled Substance Compliance Expert Systems, which include the compilation of legislative datasets from North America and key European countries. A team of experts drawn from major life science organisations, including AstraZeneca, Bayer, GlaxoSmithKline, Merck, Novartis and Roche compiled a dataset of over 400 chemical structures to challenge the vendors‘ systems. The dataset contained both controlled and non-controlled structures across a range of chemical classes and legislative schedules. The vendors were then asked to predict the controlled status of each chemical structure with reference to legislation from the USA, UK and Switzerland. Each of these countries has taken a different legislative approach to defining controlled substances, but both expert systems were able accurately to predict the classification of these test structures.
While we are confident in the implementation of the cheminformatics technology by ChemAxon/Patcore and Scitegrity, we are limited by the interpretation of the legislation to generate the rules utilized by these expert systems. We have found real benefits in bringing together experts from across the world to review the sometimes ambiguous and often difficult-to-interpret legislation. As such, the CSCS project will be creating an industry-leading Controlled Substance Compliance Services Community of Interest. This Community will help continue the work of this group of experts while improving the understanding and interpretation of controlled substance legislation from around the world.
About the Pistoia Alliance
The Pistoia Alliance is a cross-company members’ organisation committed to lowering the barriers to innovation in life sciences R&D byimproving the interoperability of R&D business processes through precompetitive collaboration. It is a type 501 (c) (6) not-for-profit company formally incorporated in the State of Delaware and draws its membership from Pharma R&D and other Life Science R&D organisations, commercial information providers, technology companies and other publically funded research organisations. The Pistoia Alliance brings together the key stakeholders to identify the root causes that lead to R&D inefficiencies and then develops best practices and technology implementations to overcome common obstacles.
