The Importance of Precise Patient Stratification in Precision Medicine

Patient stratification is a process in drug discovery and development that involves categorizing patients into subgroups based on various characteristics such as genetics, molecular profile, or clinical data. This stratification is fundamental for precision medicine, to achieve tailored medical treatments to individual patients or patient groups based on these characteristics.

Patient stratification allows drug developers to achieve the following:

  • Enhanced Drug Efficacy and Safety: By understanding which patient groups are more likely to respond to a certain drug, developers can create more effective and safer treatments. It reduces the ‘one-size-fits-all’ approach.
  • Efficient Clinical Trials: Stratification can lead to more efficient clinical trials by selecting patient populations more likely to benefit from the drug, thereby reducing trial size and cost, and avoids waste of time and resources.
  • Reduction in Drug Development Failure: Many drugs fail in late-stage trials due to lack of efficacy in a broad patient population. Stratification can identify responsive subpopulations early, reducing failure rates.
  • Precision Medicine: It facilitates the development of precision medicine, allowing treatments to be tailored to specific patient subgroups.

Achieving Precise Patient Stratification is Challenging

  • Complexity of Diseases: Many diseases, like cancer, have complex and heterogeneous pathologies, making it challenging to identify clear stratification markers.
  • Ethical and Regulatory Considerations: Stratification raises ethical concerns about  access to treatment and patient privacy, such as access to genetic information. 
  • Cost and Resource Intensity: The process of identifying and validating biomarkers for stratification is often expensive and resource-intensive.
  • Data Integration and Analysis: Integrating and analyzing vast amounts of multi-modal data (genomic, proteomic, clinical, etc.) to identify relevant stratification markers is technically challenging.
