Biography as the Missing Variable in Drug Development: A Case for Bio-Biographical Mechanistic Profiling
1Temple University, Philadelphia, Pennsylvania, USA.
Biographical factors like stress and trauma significantly impact treatment response by altering biological pathways. Measuring these biographical elements alongside biomarkers can improve patient stratification for therapies like immune checkpoint inhibitors.
Area of Science:
- Oncology
- Immunology
- Psychoneuroimmunology
Background:
- Clinical trial failures often stem from unmeasured biological heterogeneity.
- Biographical factors (stress, trauma, social isolation) represent a neglected source of heterogeneity.
- These biographical elements operate via molecular pathways targeted by modern therapeutics.
Purpose of the Study:
- To introduce Bio-biographical mechanistic profiling (BBMP) as a method to measure biographical influences on drug pathways.
- To identify patients whose treatment pathway engagement is modified by biographical factors.
- To bridge the gap between pathway-matched treatment and personalized medicine.
Main Methods:
- Prospective, mechanism-matched measurement of biographical factors and standard biomarkers.
- Utilizing existing data from non-small cell lung cancer and melanoma studies.
- Assessing immunological intermediaries linking biographical measurement to treatment response.
Main Results:
- Pretreatment biographical measurement predicts immune checkpoint inhibitor response in cancer patients.
- Demonstrated that the biography-heterogeneity axis is both detectable and pharmacologically relevant.
- Established proof of concept for BBMP's ability to identify modified biological pathways.
Conclusions:
- Biographical factors are crucial, measurable contributors to patient heterogeneity in clinical trials.
- BBMP offers a novel approach to personalize cancer treatment by accounting for life experiences.
- Integrating biographical data can enhance the efficacy of targeted therapies, particularly immune checkpoint inhibitors.
