Field of Activity


Founded in February 2024 by CEO Sébastien Lasnier, SYNAPTYS Neuroscience is a biotech company based in the scientific cluster of the Saclay plateau (near Paris). It is supported by IncubAlliance, the deeptech incubator of Paris-Saclay, and Genopole through its Upscale Bio program.

SYNAPTYS is pioneering a new therapeutic approach that could transform the lives of patients living with Alzheimer’s disease.

DESCRIPTION OF ACTIVITY

SYNAPTYS neuroscience is developing SYS-0108, the first Neuro-Synergistic Conjugate for Alzheimer’s disease—a disruptive, patented innovation inspired by combination strategies used in oncology.

SYS-0108 combines two existing molecules—Memantine and Cholecalciferol—both of which have demonstrated positive effects. Using an AI-inspired boosting method, the action of Memantine is amplified to enhance its neuroprotective efficacy.

SYS-0108 is based on four inseparable, integrated processes:

  • Innovative composition: Memantine + Cholecalciferol
  • Targeted brain delivery: precise binding to key receptors involved in Alzheimer’s (NMDA and VDR)
  • Chronopharmacology: time-specific administration to enable optimal neuroprotective effects
  • Optimized dosing: experimentally validated ratio for long-lasting efficacy

SYS-0108 acts at the core of Alzheimer’s pathophysiology to slow disease progression, mitigate cognitive decline, and preserve brain function.

A rapidly growing market: By 2050, over 150 million people are expected to be affected worldwide, representing a $20+ billion/year market, with families eagerly awaiting truly effective treatments.

Currently in preclinical development, SYNAPTYS Neuroscience is actively seeking academic and financial partners to accelerate clinical advancement.

  • In brief
    • Focus: Development of SYS-0108, the first Neuro-Synergistic Conjugate combining Memantine and Cholecalciferol, enhanced via an AI-based boosting strategy
    • Current Phase: Preclinical
    • Innovation Highlights: Combination therapy based on four integrated pillars (composition, targeting, chronopharmacology, dosing) + AI-driven boosting
    • Target Market: 150M patients by 2050 – $20B/year – critical unmet medical need
