Exploring the reuse of clinical data for advanced AI pharma research purposes

By Anna Choma

Accessing medical data for research purposes can be exceedingly challenging, just to mention privacy concerns and regulatory restrictions. Striking a balance between protecting patient confidentiality and enabling valuable research is a complex and ongoing dilemma in the healthcare field. However, as a company providing custom algorithms development services with a research team onboard, we believe in an obligation to maximize the value and utility of this resource. The reuse of clinical data sets can provide significant benefits to both patients and sponsors. Reusing clinical data has been recognized for decades as a valuable approach to improving healthcare outcomes and reducing costs [1] and it is still an area of increasing interest across the pharmaceutical industry. 

Clinical data reuse – accelerating clinical research

Using clinical trial data in drug discovery and other health-related scientific investigations boosts the process of discovering and advancing new, improved treatments, ultimately improving patients’ lives and benefiting society as a whole.  

Clinical data reuse can accelerate clinical research by expediting patient recruitment, enabling hypothesis testing, providing cost-effective access to a broader range of clinical information for research applications, and running feasibility studies to use historical data in clinical trials. But what are the other goals you may achieve by clinical data reuse or secondary use? 

Goals you may achieve by secondary use

The European Federation of Pharmaceutical Industries and Associations (EFPIA) in its framework for secondary use of clinical data [2] provides examples of health research purposes for which clinical trial data might be re-used: 

  • to explore novel hypotheses that would otherwise necessitate launching a new research study involving medical interventions on patients. These fresh hypotheses might focus on investigating alternative treatments or enhancing our comprehension of disease mechanisms, among other possibilities 
  • for regulatory purposes, such as conducting safety studies at the request of authorities and for research (often done in collaboration) involving the pooling of clinical trial data from multiple studies to support in treatment evaluation and drug development.  
  • to enhance the efficiency, design, and methods of future clinical trials as well as to allow independent researchers to validate or scrutinize the original results 
  • and last but not least: to create and test new healthcare technologies, such as AI-based algorithms. 

In particular, in pursuit of this final objective, we bring extensive expertise to the table. Throughout the years, we’ve refined our skills and deepened our knowledge in utilizing clinical data to propel the creation of state-of-the-art AI solutions. 

Clinical data reuse to create and test AI-based algorithms

Particularly when it comes to the aforementioned objective, we possess a wealth of extensive expertise and knowledge, just to mention projects described in scientific papers. 

  1. We introduced a complete algorithm for the automated detection of cirrhosis using CT that additionally benefits from the clinically inspired and radiomic features.

  2. We developed an algorithm that in the first step identifies tumor sub-regions such as the enhancing tumor, peritumoral edema, and surgical cavity, and then calculates volumetric and bidimensional measurements based on the current Response Assessment in Neuro-Oncology (RANO) criteria.
