Personalised medicine has yet to deliver on its transformative promise, according to recent discussions highlighting the sector’s challenges. While companies readily offer products for tracking biomarkers or creating tailored nutrition plans, the field still struggles to address the significant variations in how individuals respond to diseases and treatments.

The concept of personalised medicine is compelling; it acknowledges the vast differences in human genetics, microbiomes, and overall health. Such differences can play a critical role in how individuals experience and cope with diseases. This week, two notable cases underscore the complexity of personalised medicine.

Research indicates that almost everyone will encounter the Epstein-Barr virus at some point in their lives. However, genetic variants may hinder some individuals’ ability to effectively expel the virus from their bodies. This variation could elucidate why the virus remains harmless for most but is linked to autoimmune conditions like multiple sclerosis in others. Similarly, certain individuals demonstrate resilience against misfolded proteins that can lead to neurodegenerative diseases.

Understanding these diverse disease processes requires a comprehensive approach to human biology. This involves collecting extensive data on various factors, including individuals’ DNA and immune responses, to discern the underlying mechanisms at play. The path forward also necessitates meticulously designed clinical trials for new treatments.

Traditionally, clinical trials have applied a one-size-fits-all approach, administering the same treatment to large groups of patients with similar conditions. Yet, as research shows, responses can differ significantly among individuals. Recognizing and identifying the specific populations likely to benefit from particular treatments is crucial for advancing personalised medicine.

One area where progress has been made is in cancer treatment. While various growths fall under the “cancer” label, they represent distinct diseases requiring tailored treatment strategies. There is no single “cure for cancer”; rather, there are numerous pathways to manage and treat different types effectively.

The challenges facing personalised medicine are substantial, yet they present an opportunity for meaningful advancements, particularly for conditions such as Alzheimer’s and multiple sclerosis. As the healthcare community continues to navigate these complexities, it is essential to address the gaps in understanding and treatment in order to fulfill the potential of personalised medicine.

This ongoing dialogue reflects a broader commitment to improving healthcare outcomes through a more individualized approach, paving the way for innovations that could significantly alter patient care in the future.
