Neurodegeneration Pipeline

SNP318: Lead Alzheimer’s Disease Program

SNP318 represents SciNeuro’s most advanced candidate and exemplifies the company’s approach to neuroinflammation modulation.

Mechanism of Action

SNP318 is a novel small molecule that modulates neuroinflammation through targeting Toll-like Receptor 4 (TLR4), a key pattern recognition receptor implicated in neurodegenerative disease pathology^{3PEComas: A review of imaging and clinical features.2024 · Clin Imaging · DOI doi: 10.1016/j.clinimag.2024.110332 · PMID 39442258Open reference}. TLR4 signaling plays a critical role in microglial activation and the production of pro-inflammatory cytokines that contribute to neuronal dysfunction and death.

The mechanism involves:

TLR4 Modulation:

• SNP318 binds to TLR4 and modulates its signaling cascade

• Reduces downstream activation of NF-κB and other inflammatory transcription factors

• Decreases production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6^{4Microglia in Alzheimer's disease2022 · Journal of Experimental Medicine · PMID 35025635Open reference}

Microglial Regulation:

• Shifts microglial activation state from pro-inflammatory to more beneficial phenotypes

• Reduces excessive microglial activation that contributes to synaptic loss

• Preserves microglial phagocytic function necessary for clearing pathological proteins^{5Advances in Prostate Cancer Biomarkers and Probes.2024 · Cyborg Bionic Syst · DOI doi: 10.34133/cbsystems.0129 · PMID 40353136Open reference}

Neuroprotection:

• Protects neurons from inflammatory-mediated damage

• Preserves synaptic integrity and function

• Supports neuronal survival in the presence of chronic neuroinflammation

Clinical Development Status

SNP318 has advanced through preclinical development into Phase 1 clinical trials:

The clinical development program has demonstrated:

• Acceptable safety and tolerability in single and multiple ascending doses

• Pharmacokinetic properties suitable for once-daily oral dosing

• Central nervous system penetration demonstrated in preclinical models

• Target engagement biomarkers consistent with mechanism of action^{6SciNeuro PharmaceuticalsOpen reference}

Rationale for Neuroinflammation Targeting

SciNeuro’s focus on neuroinflammation reflects the growing recognition of this pathway’s central role in neurodegenerative disease progression:

Chronic Inflammation in AD: Neuroinflammation is present throughout Alzheimer’s disease progression, beginning early in the disease process and amplifying as pathology accumulates. Activated microglia surround amyloid plaques and produce pro-inflammatory cytokines that contribute to synaptic dysfunction, tau pathology propagation, and neuronal death

Multiple Pathologies, Common Mechanism: Both Alzheimer’s disease and Parkinson’s disease involve neuroinflammation as a common pathological feature. This creates opportunities for therapeutic approaches that target shared inflammatory mechanisms, potentially applicable across multiple neurodegenerative conditions^{7Precision interventional radiology.2021 · J Interv Med · DOI doi: 10.1016/j.jimed.2021.09.002 · PMID 35586378Open reference}.

Complementary to Amyloid Targeting: While amyloid-targeting therapies have shown efficacy in clearing amyloid plaques, they have not yet demonstrated robust clinical benefit. Combining amyloid clearance with neuroinflammation modulation represents a rational combination approach that could enhance therapeutic outcomes.

Disease-Modifying Potential: Unlike symptomatic treatments that address neurotransmitter deficits, neuroinflammation modulation offers the potential to slow or halt disease progression by targeting upstream pathological mechanisms.

SNP210: Parkinson’s Disease Program

SciNeuro’s second most advanced program targets neuroinflammation in Parkinson’s disease:

Target and Approach

SNP210 is in preclinical development for Parkinson’s disease, with a mechanism similar to SNP318 but optimized for PD-specific pathologies:

• Targeting neuroinflammation associated with dopaminergic neuron loss

• Addressing microglial activation in substantia nigra

• Potentially protecting remaining dopaminergic neurons from inflammatory damage

Development Timeline

SNP210 is in the lead optimization phase, with IND-enabling studies planned to begin in 2025.

Science and Rationale

Neuroinflammation in Alzheimer’s Disease

The role of neuroinflammation in Alzheimer’s disease has evolved from being considered a secondary phenomenon to a central pathological mechanism. Multiple lines of evidence support targeting neuroinflammation in AD^{8JAK-STAT pathway targeting for the treatment of inflammatory bowel disease.2020 · Nat Rev Gastroenterol Hepatol · DOI doi: 10.1038/s41575-020-0273-0 · PMID 32203403Open reference}:

Microglial Activation: Microglia are the brain’s resident immune cells and play essential roles in brain homeostasis and defense. In AD, microglia become chronically activated in response to amyloid-beta plaques and tau pathology, producing pro-inflammatory cytokines that contribute to synaptic dysfunction and neuronal death^{4Microglia in Alzheimer's disease2022 · Journal of Experimental Medicine · PMID 35025635Open reference}. This creates a feedforward loop where inflammation promotes more amyloid processing and tau pathology, which in turn triggers additional microglial activation.

Cytokine Networks: Multiple cytokines contribute to neuroinflammation in AD:

• TNF-α: Elevated in AD brains and directly toxic to neurons

• IL-1β: Implicated in synaptic dysfunction and cognitive decline

• IL-6: Associated with disease progression and cognitive impairment

Therapeutic Implications: Targeting neuroinflammation offers several advantages:

• Potential to slow disease progression independent of amyloid or tau pathology

• May complement existing amyloid-targeting approaches

• May be applicable across different disease stages

Neuroinflammation in Parkinson’s Disease

Neuroinflammation is similarly prominent in Parkinson’s disease:

Microglial Activation in PD: Post-mortem studies consistently show increased microglial activation in PD brains, particularly in regions with dopaminergic neuron loss. PET studies using TSPO ligands have confirmed microglial activation in living PD patients^{9Global Biobank Meta-analysis Initiative: Powering genetic discovery across human disease.2022 · Cell Genom · DOI doi: 10.1016/j.xgen.2022.100192 · PMID 36777996Open reference}.

Inflammatory Pathways: Multiple pathways contribute to neuroinflammation in PD:

• NLRP3 inflammasome activation

• TLR4 signaling

• Complement system activation

Blood-Brain Barrier Involvement: Neuroinflammation in PD is accompanied by blood-brain barrier disruption, which may allow peripheral immune cells to enter the brain and contribute to pathology^{2A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health.2023 · Eco Environ Health · DOI doi: 10.1016/j.eehl.2023.08.002 · PMID 38435355Open reference}0.

Protein Homeostasis and Neurodegeneration

SciNeuro also focuses on protein homeostasis, another key mechanism in neurodegeneration:

Protein Aggregation: In both AD and PD, abnormal protein accumulation represents a core pathological feature. In AD, amyloid-beta and tau form plaques and tangles; in PD, alpha-synuclein forms Lewy bodies. These aggregates are associated with cellular dysfunction and death^{2A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health.2023 · Eco Environ Health · DOI doi: 10.1016/j.eehl.2023.08.002 · PMID 38435355Open reference}1.

Cellular Clearance Mechanisms: Cells rely on multiple pathways to clear misfolded proteins:

• Autophagy-lysosomal pathway

• Ubiquitin-proteasome system

• Molecular chaperones

Dysfunction in these clearance systems contributes to protein accumulation, and enhancing clearance represents a therapeutic strategy.

Astroglial Contributions

Astrocytes also play important roles in neuroinflammation and neurodegeneration:

Reactive Astrocytes: Liddelow et al. demonstrated that neuroinflammation drives the conversion of astrocytes to a neurotoxic “A1” phenotype that contributes to neuronal death^{2A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health.2023 · Eco Environ Health · DOI doi: 10.1016/j.eehl.2023.08.002 · PMID 38435355Open reference}2.
