In brief

On 25 October 2022 leading researchers and executives from some of the world’s pioneering drug and pharmaceutical companies came together at a Financial Times Live Webinar event to discuss “The Power of Clinical Trial Tokenisation”.

Tokenisation of healthcare data is likely to be one of the next great innovations for developing life-saving drugs and treatments through the method of privacy-preserving record linkage (PPRL). This allows pharmaceutical companies to ‘tokenise’ and link previously scattered patient datasets to produce unique insights. We’ve set out the top five takeaways on tokenisation from the webinar below:

  1. How does it work? The digital token creates a pseudonymous version of a patient’s healthcare data to produce a holistic record that can be applied to other datasets, such as lab and trial data, throughout the course of a drug trial to uncover invaluable trends that are not otherwise identifiable.
  2. Which problems does this solve? Traditionally, researchers found it difficult to track patients that dropped out of studies. When coupled with issues such as patient recollection and written notes this reduced the reliability of the datasets. Now because of PPRL, researchers can collect routinely obtained healthcare data in real-time and link randomised control trial data and registries with real-world data.
  3. What’s the promise of tokenisation? Tokenisation creates the ability to see the true effects of drug trials over the long term that might not have been otherwise possible. Wider populations can be integrated more easily into these datasets, creating sample diversity and increasing comparative accuracy. Some areas highlighted as greatly benefitting from PPRL are oncology, mental health, and digital therapeutics. Health regulators may also start to request PPRL information to build multi-layered datasets when conducting their own regulatory assessments. This could be particularly useful in gene testing where patients need to be followed for five or more years.
  4. What are the challenges? Key barriers are ensuring health data does not become compromised, and (where needed) obtaining patients’ consent – patients’ familiarity with the PPRL process is vital to this. Additionally, external stakeholders’ familiarity is important to obtain operational support by, for example, educating data collection sites. Tokenisation of healthcare data presents huge opportunities, but these hurdles will need to be overcome, and this is dependent on available resources. To realise maximum value at an enterprise level, technical, legal, and governance teams will need to collaborate to see the most benefit.
  5. The impact of data privacy: Increasingly complex and varying data privacy regimes in different jurisdictions make operationalising PPRL difficult from a practical and legal perspective. So far PPRL has emerged as a US-centric focused method and more work is needed to harmonise the process, including standardisation of external providers that are able to tokenise the data. Nevertheless, tokenisation could be used as a method for risk-sharing through aggregation of healthcare data in the future.

Speakers included: Sidharth Jain, Head of Global Development Data Science at Janssen R&D; Jason Lott, Vice President of Global Integrated Evidence Generation, Specialty Medicine, Integrated Care, and Cell-Gene Therapy at Bayer Pharmaceuticals; Kathleen Mandziuk, Vice President of Real World Solutions and Tokenisation at ICON; Lucinda Orsini, Vice President of Value and Outcomes Research at COMPASS Pathways; Henry Wei, Head of Development Innovation at Regeneron; and, Sarah Neville, Global Health Editor at the Financial Times.
