Leadership at Pathways Neuro Pharma

As President & CEO of Pathways Neuro Pharma, Mr. Mack is leading the development of next-generation, genetically validated gene therapies for Juvenile Parkinson’s Disease (JPD) and related rare neurodegenerative disorders.

Pathways’ strategy targets two foundational biological drivers of early neurodegeneration:

1. Mitochondrial Gene Replacement

Focused on restoring mitochondrial quality-control pathways in patients with inherited deficiencies such as PINK1, with the objective of engaging upstream mechanisms of neuronal survival and mitigating early cellular deterioration. (Patent pending)

2. Receptor-Level Dopaminergic Modulation

Designed to enhance physiological dopaminergic responsiveness without the chronic overstimulation associated with traditional dopamine replacement therapies—aimed at reducing tolerance, dyskinesia, and neuropsychiatric complications over time.

AAV Gene Therapy Delivery Strategy

Pathways utilizes clinically established AAV delivery systems selected for CNS-targeted applications and translational continuity. The platform emphasizes modalities that:

• Support pediatric and young-adult patient safety
• Align with regulatory precedent
• Enable durable, scalable therapeutic expression
• Reduce downstream manufacturing and commercial complexity

This approach preserves flexibility in capsid selection based on indication, regulatory environment, and clinical trajectory.

What Anthony Mack Brings to Pathways and Its Partners

• Strategic partnerships with governance alignment
  Proven track record of alliances combining capital investment, board participation, and operational collaboration.
• Capital formation and public-market leadership
  Over $100 million raised across ventures, including IPO and follow-on financings.
• IP strategy and non-dilutive funding
  Extensive experience building defensible patent estates and securing NIH and DoD funding within rare and pediatric regulatory frameworks.
• Operator discipline
  Ability to translate complex science into clear development milestones, partnership strategies, and value-creating decisions for patients, investors, and strategic acquirers.

At Pathways, this leadership approach is applied with urgency and purpose: to deliver durable, disease-modifying therapies for families facing devastating neurological disease—and to build enduring value for stakeholders.

All Pathways programs are investigational. Safety and efficacy have not been established in humans.
