Lysoway Therapeutics

Company Overview

Company Overview

Lysoway Therapeutics is a clinical-stage biotechnology company dedicated to developing novel therapeutics targeting lysosomal ion channels for the treatment of neurodegenerative diseases. The company's innovative approach focuses on developing highly brain-penetrant small molecule agonists of lysosomal ion channels, particularly TRPML1 (Transient Receptor Potential Cation Channel Subfamily M Member 1) and TMEM175 (Transmembrane Protein 175), to restore autophagy-lysosomal function in age-related neurodegenerative conditions.

Founded in 2020 and headquartered in the United States, Lysoway represents a new generation of biotech companies applying insights from lysosomal biology—historically associated with rare lysosomal storage disorders—to common neurodegenerative diseases including Alzheimer's disease (AD) and Parkinson's disease (PD)[@lysoway].

The company's name combines "lysosome" with "pathway," reflecting its fundamental commitment to targeting lysosomal pathways as a therapeutic strategy for neurological disorders. This naming reflects the company's understanding that lysosomal dysfunction is a common thread connecting many neurodegenerative conditions, and that restoring lysosomal function represents a promising therapeutic approach.

The company's approach centers on the well-established link between glucocerebrosidase (GCase) deficiency and Parkinson's disease risk. Mutations in the GBA1 gene, which encodes GCase, represent one of the most significant genetic risk factors for Parkinson's disease, increasing risk by 5-20 fold in carriers of certain variants. This genetic connection has catalyzed substantial interest in developing therapies that can enhance GCase activity or otherwise compensate for lysosomal dysfunction in dopaminergic neurons["@schapira2019"][@sidransky2011].

Mission and Vision

Lysoway's mission is to develop disease-modifying therapies for neurodegenerative diseases by targeting the autophagy-lysosomal pathway—the cellular cleanup system that becomes progressively dysfunctional with age and is particularly compromised in Alzheimer's and Parkinson's disease.

The company envisions a future where neurodegenerative diseases can be treated not by managing symptoms, but by addressing the underlying cellular dysfunction that drives disease progression. By restoring lysosomal function, Lysoway aims to:

• Clear toxic protein aggregates (beta-amyloid, tau, alpha-synuclein)
• Restore neuronal health and function
• Slow or halt disease progression
• Improve cognitive and motor outcomes for patients

Science and Technology Platform

Lysosomal Biology in Neurodegeneration

Lysosomes serve as the cellular recycling centers, degrading and recycling proteins, lipids, and organelles through the autophagy-lysosomal pathway. This system becomes progressively less efficient with aging, leading to the accumulation of damaged proteins and organelles that characterize neurodegenerative diseases.

Key findings supporting the lysosomal therapeutic approach include[@lysosomal_dysfunction_ad][@autophagy_neurodegeneration]:

TRPML1 Agonists

TRPML1 (also known as MCOLN1) is a lysosomal cation channel that plays a critical role in[@trpml1_biology]:

• Lysosomal Calcium Release: Regulates lysosomal calcium signaling essential for autophagy initiation
• Autophagy Induction: Calcium release from lysosomes triggers autophagy initiation
• Lysosomal Trafficking: Controls movement of materials within lysosomes
• Phagolysosomal Fusion: Enables fusion of autophagosomes with lysosomes

• Enhanced autophagy flux and clearance of protein aggregates
• Improved lysosomal function and cellular clearance
• Protection against oxidative stress and mitochondrial dysfunction
• Reduction in neuroinflammation

TMEM175 Agonists

TMEM175 is a lysosomal potassium channel that[@tmem175_biology]:

• Regulates Lysosomal pH: Maintains optimal lysosomal acidity for enzymatic function
• Modulates Autophagy: Potassium flux influences autophagy initiation
• Protects Against Stress: Channel activity supports lysosomal membrane stability
• Coordinates with mTOR: Works with mTOR signaling to regulate lysosomal biogenesis

Small Molecule Approach

Lysoway's lead programs utilize small molecule agonists that:

• Brain Penetrance: Cross the blood-brain barrier effectively
• Lysosomal Targeting: Accumulate in lysosomal compartments
• Selectivity: Avoid off-target effects on other ion channels
• Pharmacokinetic Properties: Suitable for chronic dosing

• Gene Therapy: Permanent but irreversible genetic modification
• Enzyme Replacement: Limited by inability to cross the blood-brain barrier
• Protein Therapeutics: Limited CNS penetration

Pipeline and Programs

Development Pipeline

| Drug | Mechanism | Target | Indication | Stage |
|------|-----------|--------|------------|-------|
| LY-001 | TRPML1 agonist | MCOLN1 | Parkinson's Disease | Preclinical |
| LY-002 | TMEM175 agonist | TMEM175 | Alzheimer's Disease | Discovery |
| LY-003 | Dual TRPML1/TMEM175 agonist | MCOLN1/TMEM175 | Parkinson's Disease | Discovery |

LY-001 (TRPML1 Agonist)

The lead program targets Parkinson's disease through TRPML1 activation:

• Mechanism: Small molecule agonist of TRPML1 lysosomal cation channel
• Target: Enhanced autophagy-lysosomal function in dopaminergic neurons
• Indication: Parkinson's disease (particularly in patients with GBA1 mutations or idiopathic PD)
• Stage: Preclinical

LY-002 (TMEM175 Agonist)

The second program targets Alzheimer's disease:

• Mechanism: Small molecule agonist of TMEM175 lysosomal potassium channel
• Target: Restoration of lysosomal pH and function in neurons
• Indication: Alzheimer's disease
• Stage: Discovery

Dual Agonist Program

Lysoway is also developing compounds that activate both TRPML1 and TMEM175, potentially providing enhanced therapeutic benefit by addressing multiple aspects of lysosomal dysfunction simultaneously.

Scientific Rationale

Lysosomes and Neurodegeneration

The lysosomal pathway is critical in neurodegeneration for several interconnected reasons:

GBA1-PD Connection

The link between GBA1 (glucocerebrosidase) mutations and Parkinson's disease provides compelling evidence for the lysosomal therapeutic approach[@schapira2019][@mazzulli2011]:

• Risk Increase: GBA1 mutation carriers have 5-20x increased risk of developing PD
• Mechanism: Loss of GCase function leads to glucosylceramide accumulation
• Alpha-Synuclein: Lipid alterations affect alpha-synuclein aggregation and clearance
• Therapeutic Window: Enhancing GCase activity or other lysosomal functions may provide benefit

Autophagy and Protein Homeostasis

The autophagy-lysosomal pathway is the primary mechanism for cellular protein quality control[@kim2020][@taylor2023]. Key points include:

• Macroautophagy: Bulk degradation of proteins and organelles via autophagosomes
• Chaperone-Mediated Autophagy: Selective degradation of specific proteins
• Microautophagy: Direct uptake of cytoplasmic material by lysosomes

• Parkinson's Disease: Alpha-synuclein, LRRK2, GCase
• Alzheimer's Disease: Beta-amyloid, tau, APP
• ALS: TDP-43, SOD1, FUS

mTOR and Lysosomal Biogenesis

The mTOR (mammalian target of rapamycin) pathway tightly regulates lysosomal function[@mtor_lysosomal][@taylor2023]:

• mTORC1 Signaling: Inhibits autophagy when nutrients are abundant
• Lysosomal Biogenesis: mTOR regulates transcription of lysosomal genes
• Therapeutic Implications: mTOR inhibitors can promote autophagy but have broad effects

Clinical Development Strategy

Target Patient Populations

Lysoway's initial clinical development focuses on:

Biomarker Strategy

The company is developing biomarkers to identify patients most likely to respond:

• Lysosomal Function Biomarkers: Measures of lysosomal enzyme activity
• Autophagy Markers: LC3, p62 levels in cerebrospinal fluid
• Genetic Markers: GBA1 mutation status, other lysosomal variants
• Imaging Biomarkers: PET tracers for amyloid and tau
