SUMMARY:Seminar - Tanya Simuni
DESCRIPTION:Venue: Centre Broca \n\nPr. Tanya Simuni\, MD\, FAAN \nArthur C. Nielsen Professor of Neurology\nDivision Head\, Parkinson’s disease and Movement Disorders Center\nNorthwestern University Feinberg School of Medicine\nhttps://www.feinberg.northwestern.edu/\nInvited by Wassilios Meissner (IMN) \nTitle\nThe Era of Disease Preventive Neurology: From the biological definition of Parkinson’s disease to disease prevention trials\nAbstract\nA biologic research definition and staging framework for neuronal alpha‑synucleinopathies\, including Parkinson’s disease and dementia with Lewy bodies\, is essential for improving clinical trial design and accelerating therapeutic development. Neuronal Synuclein Disease (NSD) and its companion Integrated Staging System (NSD‑ISS) represent a biologic definition and staging construct developed collaboratively by stakeholders across academia\, industry\, advocacy organizations\, and\, importantly\, individuals with lived experience. Much of this framework has been informed and enabled by insights generated through the Parkinson’s Progression Markers Initiative (PPMI). This talk will summarize the key concepts of the current NSD‑ISS\, highlight the latest expanded biomarker initiatives within PPMI\, and outline plans for the next iteration of NSD‑ISS based on emerging knowledge. \nThe second part of the talk will describe The Path to Prevention Platform Trial (P2P)\, a multi‑center\, multi‑regimen\, proof‑of‑concept\, phase 2A randomized clinical trial designed to evaluate the safety and early efficacy of investigational therapeutics for individuals in the Early‑Stage NSD population. P2P is embedded within PPMI\, meaning its conceptualization\, design\, and implementation are driven by learnings from the PPMI study. P2P represents an important step toward defining the clinical trial and regulatory pathways for interventions targeting early‑stage NSD. \nBiosketch\nMy major contribution to science is international leadership in advancement of translational science in the development of therapeutics for slowing progression of Parkinson’s disease. I have extensive expertise in clinical research\, including design and conduct of single- and multicenter studies in early PD. Under my leadership\, we completed the Phase 3 multicenter isradipine study (STEADY-PD3) across 56 sites. I have served as PI on multicenter Phase 2 PD trials (e.g.\, NILO-PD) and more than 30 other projects. I am Site PI and on the Leadership Team for PPMI\, lead planning for the Path to Prevention platform in prodromal PD\, and co-lead the international working group defining and staging Neuronal Synuclein Disease (NSD). I also lead the NeuroNEXT (NEXT) Northwestern Clinical Site and serve on governance bodies for PD genetics and prevention initiatives. \nPublications\n\nBrooker SM\, Pasquini J\, Choi SH\, Simuni T\, et al.
