Workshop B | Reimagining Translational Validity: Optimizing In Vivo Models for Predictive Power in Alzheimer’s & Parkinson’s Drug Development
1:00 pm

Animal models remain the crucial, but often weakest, link between discovery and clinic. This workshop dissects why toxin‑based and first‑gen transgenic models miss human disease complexity and progression and showcases next‑generation options such as hybrid humanized strains, gut‑origin paradigms, and vector‑delivered pathology that better mirror biomarker change and clinical progression. Walk away with clear criteria and partnership tips for selecting, benchmarking, and refining in‑vivo systems that sharpen translational signals and cut downstream risk.

Key Questions to Be Addressed:

  • What criteria should define a ‘fit-for-purpose’ in vivo model in neurodegenerative disease, especially when pathological complexity and slow disease progression challenge current paradigms?
  • How can we enhance the translatability of in vivo findings to clinical endpoints, particularly in tracking neuroinflammatory, synaptic, or resilience-related pathways beyond amyloid and α-synuclein?
  • With combinatorial and multi-target strategies becoming more common, how do we best model additive or synergistic effects across amyloid, tau, α-synuclein, and neuroinflammatory cascades?
  • What role can newer disease paradigms, such as gut-brain axis induction or viral vector delivery, play in enhancing the physiological relevance of current models?
  • How do we benchmark CROs and academic centres developing novel models? What best practices and vendor collaborations can accelerate model refinement and validation?

Companion Diagnostic Co-Development for New Imaging Brain Scans or as Outcome Measures
11:00 am
  • How can sponsors and tracer makers team up (for example, the widely used but still investigational Lantheus tau tracer) to collect validation data side-by-side with regulatory approval in mind for patient pre-selection
  • How co-developing can enable the label to specify a clear uptake cut-off instead of treating “everyone”
  • Use of Hippocampal volume as eligibility criterion and as an outcome measure in APOE-4 carriers with AD
  • Partnering early avoids the hold-up when the diagnostic lags behind, allowing doctors to use the scan on launch day to pick the right patients
