How Precision Neuroscience and Drug Synergies Could Advance Neurology

Interview with Laurence Barker, Partner at Dementia Discovery Fund - SV Health Investors, and former Global Head of Investment Management at GSK

In a recent interview with Laurence Barker, a partner at SV Health Investors and a key figure in the Dementia Discovery Fund franchise, we discussed the evolving landscape of biotechnology and the advances toward tackling dementia and other neurodegenerative conditions.

Laurence's insights shed light on the critical role of so-called “precision neuroscience” in addressing one of today's most daunting medical challenges: dementia. 

Drug discovery related to neurodegenerative diseases is, characterized by a high rate of clinical trial failures and a dire need for effective therapeutics, stands as a significant hurdle in medical science. 

By investing in and building companies focused on novel mechanisms, the fund aims to leverage global science in pursuit of breakthrough treatments.

For instance, the DDF's support for companies like Alchemab Therapeutics and Cerevance, are examples of the fund’s focus on leveraging artificial intelligence (AI) and big data in the battle against neurodegenerative diseases.

Alchemab Therapeutics stands out for its innovative approach to identifying protective antibodies in individuals who have remained free from neurodegenerative conditions.

By employing AI to sift through extensive antibody repertoires, Alchemab seeks out unique subsets that offer a shield against diseases such as Alzheimer's.

On the other hand, Cerevance, with its roots in Cambridge, is advancing its platform technology focused on the neuroinflammatory pathways implicated in Alzheimer's disease.

The company secured some significant partnerships, notably with pharmaceutical giant Merck.

The backing of Alchemab Therapeutics and Cerevance by the DDF is reflective of a broader strategy aimed not merely at funding existing ventures but at stimulating the biotech landscape to cultivate and support new entities from inception.

The Role of Precision Neuroscience

At the heart of Laurence's discussion is the concept of precision neuroscience—a term that encapsulates the future of neurodegenerative disease treatment. 

Drawing parallels with the success of precision medicine in oncology, Barker emphasizes the necessity of understanding individual patient profiles and disease states.

This approach is pivotal in developing effective drug combinations, marking a paradigm shift from single-agent therapies to more nuanced, synergistic treatment strategies.

Artificial intelligence (AI) and data play indispensable roles in this new era of precision neuroscience, but algorithms are only as good as data they can train on. 

With the UK pioneering significant genomics initiatives, such as the UK Biobank and Our Future Health project, vast datasets are becoming available. These resources are invaluable for understanding disease progression, identifying biomarkers, and tailoring treatments to individual patient profiles. 

Laurence highlights several examples within the Dementia Discovery Fund's portfolio where AI-driven analysis of genetic, proteomic, and clinical data is leading to novel target discovery and therapeutic development.

Notably, Laurence emphasized the significant potential of drug combination strategies in the treatment of neurodegenerative diseases, particularly dementia. 

According to his ideas, future breakthroughs in this field are likely to emerge from understanding how drugs can be used together in synergistic or complementary ways to maximize their therapeutic impact. 

Drawing on successful precedents in oncology, where combination therapies have revolutionized treatment, Laurence suggests a similar approach could yield substantial benefits in neurodegeneration.

This shift toward combination therapies, informed by precision neuroscience, represents a hopeful horizon for tackling diseases that have long been considered intractable.


The UK's Biotech Ecosystem and Global Leadership

The interview also touches on the UK's biotech ecosystem, which Barker believes is well-positioned to lead in the biotech advances, provided it continues to foster innovation, attract global talent, and secure investment. 

Key to maintaining and expanding this leadership will be enhancing the venture capital landscape, supporting a conducive regulatory environment, and facilitating clinical research within the NHS framework.

Laurence comments on the recent report by the Tony Blair Institute for Global Change, titled "The New National Purpose: Leading the Biotech Revolution." There are some high level insights:

  • The report encourages the UK to become a leader in biotech worldwide.

  • Emphasizes creating new ideas in biotech, particularly for tackling serious health issues such as dementia.

  • Underlines the importance of working together across universities, businesses, and the government to make progress in biotech.

  • Recommends not only investing in current businesses but also starting new ones to grow the biotech field.

  • Stresses attracting investments from both the UK and abroad to strengthen the UK's role in biotech.

  • Highlights the need for an environment that supports venture capital, with help from organizations like British Patient Capital and the British Business Bank for new biotech projects.

  • Advises improving rules and healthcare systems to support more medical research in the UK, helping the biotech industry.
