Transcript

  • 1. Barriers and Opportunities for Investment in Research to find a Cure for Dementia by 2025: Funding the Scientific Challenge Ahead Lefkos T Middleton MD, FRCP Neuroepidemiology and Ageing Research Unit School of Public Health Imperial College London
  • 2. Life cycle management File and launch Phase III PoC to Phase III FTIH- ph II to PoC Pre- clinical Lead to Candidate Target to Lead Gene function to target Disease selection Target selection Success rate <8% 25% <30% ~1,000,000,000 USD > 12 years The R&D Pipeline: A Saga of High Attrition and High Financial Risk For dementia, 3 NMEs (only symptomatic drugs) out of 106 since 1998 = Market Failure
  • 3. P-tau NFTs GSK3b Dementia Ab oligomers Ab aggregates APP 2 COOH g-secretase BACE1 NH + APP Insulin Degrading Enzyme (IDE) pro-inflammatory cytokine & ROS release pro-inflammatory cytokine & ROS release Cell Death Still more unknowns than knowns in the Amyloid – Tau Cascade Despite their dominance in R&D over 2 decades (also in funding) ? ? ? ? ?
  • 4. • Common, chronic and slowly progressive. • Heterogeneity and Nosological Boundaries still not fully understood (AD vs VaD vs LBD). But 75% of dementia patients >75 years of age have mixed pathologies. • NIA-AA 2011 Criteria for AD • Etiology and physiopathology neither linear nor additive but, like a ballet choreographed interactively over time, involving genomic and a multitude of evolving environmental factors. Envrn’t Genes A Key Barrier resides in our poor understanding of disease and it’s boundaries ?
  • 5. In order to fully explore the Causes of Dementias, we need to create a new “Innovation Eco-system” Aggregation of Misfolded Ab and phosphorylated Tau Metabolic Syndrome Insulin Resistance Mitotoxicity- Mitochondrial dysfunction Ca2+ homeostasis Excitotoxicity Metabolic stress Oxydative stress Inflammation Ageing Processes Telomere Length Age-related Neurotrophic Factor Withdrawal Neurotransmitters (GABA, etc)
  • 6. Complex Human Diseases are heterogeneous Epidemiology Clinical Manifestations DNA variation - RNA-omics Imaging Systems Biology Targeted Disease Phenotypes Understanding Disease New Targets New drugs New indications Biomarkers for Risk/ Prediction Progression Response Unravelling Disease through Studies of Prospective Cohorts is a key R&D step in the Precision Medicine era (2015 and beyond) L Middleton, GSK R&D Conference, 2005
  • 7. Life cycle man’ment File and launch Phase III PoC to commit to Phase III FTIH- ph II to PoC Pre- clinical Lead to Candidate Target to Lead Gene function to target Disease selection Target selection Understanding Disease New Targets & New Indications Prospective cohorts Clinical & Genetic, Biomarkers & Systems Biology Big Data Studies Susceptibility Alleles & Rare Variants
  • 8. Life cycle man’ment File and launch Phase III PoC to commit to Phase III FTIH- ph II to PoC Pre- clinical Lead to Candidate Target to Lead Gene function to target Disease selection Target selection Understanding Disease New Targets & New Indications Prospective cohorts Clinical & Genetic, Biomarkers & Systems Biology Big Data Studies Susceptibility lleles & Rare Variants The Dementia Innovation Eco-system
  • 9. Next Steps • Recognise our failures (and their causes) over last 20 years. • Change Gear to accelerate, action is needed now:  Create a new Global Dementia Innovation Fund to  Invest in and leverage the Innovation Eco-system to develop new cures for dementia faster  Stimulate “Out of the box” thinking & new ideas.  Identify and implement evidence based new & disruptive solutions.  New people, diversity of skills, expertise & disciplines.  Transparency +++
  • 10. Education, Vascular Risk and leisure activities vs APoE4 from Ferrari et al, 2012
  • 11. Is dementia incidence declining? Trends in dementia since 1990 in the Rotterdam study Schrijvers et al, 2012
