A Pipeline of First-in-Class
Medicines for Neurodegeneration
We are systematically applying the power of the Cognate-AI™ platform to create a portfolio of transformative therapies for diseases of the central nervous system. Our focus is on validated targets that have historically been considered "undruggable" with conventional biologics due to the blood-brain barrier. Each program in our pipeline represents a potential breakthrough for patients and a significant value creation opportunity.

A Novel Approach to Parkinson's Disease

AET-101
First-in-Class Bispecific Antibody
The Unmet Need
Parkinson's Disease (PD) is a progressive neurodegenerative disorder that affects millions of people worldwide, with prevalence expected to double in the coming decades. There are currently no available treatments that can halt or reverse the underlying progression of the disease.
A primary pathological driver of PD is the misfolding, aggregation, and cell-to-cell spread of the protein alpha-synuclein (α-synuclein). Toxic oligomeric forms of this protein are believed to cause synaptic dysfunction and neuronal death, leading to the motor and non-motor symptoms of the disease.
Our Solution
AET-101 is a first-in-class, humanized, bispecific IgG1 antibody designed entirely by the Cognate-AI™ platform. It is engineered to perform two critical functions: first, to efficiently cross the blood-brain barrier by targeting the transferrin receptor, and second, to selectively bind and neutralize the toxic oligomeric forms of α-synuclein that propagate disease within the brain.
Key Preclinical Data Highlights
Brain Exposure
Increase vs. non-BBB-crossing antibody
Target Engagement
Reduction in α-synuclein pathology
Safety Profile
No adverse findings in tox studies
Motor Function
Significant improvement in PD models
Superior Brain Exposure
Demonstrated a greater than 30-fold increase in brain exposure compared to a non-BBB-crossing monospecific anti-α-synuclein antibody in non-human primate studies. This level of brain penetration is critical for achieving a therapeutic effect.
Robust Target Engagement
Effectively engaged and reduced soluble and insoluble α-synuclein pathologyin the brains of a transgenic mouse model of Parkinson's Disease, correlating with improved motor function.
