Mochida's neuroscience division focuses on three primary areas:
¶ Tau Pathology and Alzheimer's Disease
Mochida's lead Alzheimer's disease program targets tau protein pathology, which is closely correlated with cognitive decline in AD patients:
MO-1881 is Mochida's lead preclinical candidate for Alzheimer's disease:
Mechanism of Action
The compound is designed to:
- Inhibit tau phosphorylation: Reduce hyperphosphorylation that leads to tau dysfunction
- Block aggregation: Prevent tau protein misfolding and aggregation into oligomers and fibrils
- Enhance clearance: Promote clearance of pathological tau species
- Reduce spreading: Inhibit propagation of tau pathology between neurons
Scientific Rationale
Tau protein aggregation into neurofibrillary tangles is a hallmark pathological feature of Alzheimer's disease:
- Correlation with cognition: Tau pathology correlates more strongly with cognitive decline than amyloid plaques
- Spread patterns: Tau pathology follows predictable patterns of brain spreading
- Therapeutic target: Multiple companies are targeting tau as a disease-modifying approach
Development Status
- Preclinical validation in tauopathy models
- IND-enabling studies in progress
- Target: IND submission in 2026
Mochida's tau research program addresses multiple stages of tau pathology:
Aggregation Pathway
- Normal tau: Soluble, functional protein
- Phosphorylation: Abnormal hyperphosphorylation
- Misfolding: Conformational change
- Oligomerization: Toxic soluble aggregates
- Fibrillization: Insoluble fibrils
- Tangle formation: Neurofibrillary tangles
Therapeutic Intervention Points
- Kinase modulation (reduce phosphorylation)
- Aggregation inhibitors (prevent oligomer/fibril formation)
- Clearance enhancers (promote tau degradation)
- Spreading blockers (prevent inter-neuronal transmission)
Mochida's Parkinson's disease program focuses on developing neuroprotective agents:
Mechanism of Action
MO-2056 is designed to protect dopaminergic neurons from various insults:
- Mitochondrial protection: Preserve mitochondrial function
- Oxidative stress reduction: Scavenge reactive oxygen species
- Anti-apoptotic effects: Prevent programmed cell death
- Inflammation modulation: Reduce neuroinflammation
Dopaminergic Neuroprotection
Parkinson's disease involves progressive loss of dopaminergic neurons in the substantia nigra:
- Alpha-synuclein: Aggregation of alpha-synuclein in Lewy bodies
- Mitochondrial dysfunction: Impaired energy metabolism
- Oxidative stress: Increased oxidative damage
- Neuroinflammation: Microglial activation
MO-2056 targets multiple pathways to preserve neuronal survival.
Development Status
- Discovery stage
- Lead optimization ongoing
- Target: IND submission in 2027
Mochida's ALS program targets neuroinflammation through microglial modulation:
Microglia in Neurodegeneration
Microglia are the brain's resident immune cells:
- Surveillance: Constant monitoring of brain environment
- Activation: Response to pathological stimuli
- Neuroinflammation: Chronic activation contributes to neurodegeneration
- Phagocytosis: Clearance of debris and pathogens
Therapeutic Approach
MO-3003 aims to:
- Modulate activation state: Shift microglia toward neuroprotective phenotype
- Reduce cytokine production: Decrease pro-inflammatory signaling
- Enhance clearance: Improve phagocytic function
- Protect neurons: Reduce microglia-mediated toxicity
Amyotrophic Lateral Sclerosis Context
ALS involves progressive motor neuron degeneration:
- Sporadic and familial forms: Both genetic and environmental risk factors
- Neuroinflammation: Prominent microglial activation
- Therapeutic targets: Multiple approaches in development
Mochida's microglial modulation approach represents an innovative strategy for ALS treatment.
