Project Title

Preclinical Studies for Acid Maltase Deficiency (AMD) Gene Therapy in a Non-human Primate Model

Project Snapshot

In 2010, the AMDA awarded the Helen Walker Research Grant to Andrea Amalfitano, DO, PhD, at Michigan State University, to support a project focused on developing gene therapy approaches for Pompe disease. The goal of the project was to evaluate whether delivering the GAA gene to the liver using advanced viral vectors could enable long-term production and systemic distribution of the enzyme needed to treat the disease.

The research proposed testing this strategy in a non-human primate (baboon) model to determine whether gene transfer could safely produce circulating acid alpha-glucosidase enzyme and allow uptake by skeletal and cardiac muscle. These studies were designed as a critical step toward future clinical trials of gene therapy for Pompe disease.

Research Objectives

The project aimed to address several key questions related to treatment outcomes in Pompe disease:

1. Deliver the baboon GAA gene to the liver using an adenoviral gene therapy vector

Researchers proposed constructing a fully deleted adenovirus vector carrying the baboon acid alpha-glucosidase (GAA) gene and delivering it to baboon liver using a balloon-catheter mediated system. This approach was designed to test whether liver-directed gene transfer could safely produce a circulating enzyme in a large animal model.

2. Measure enzyme production and distribution following gene transfer

The research team planned to analyze GAA activity in plasma and muscle tissue of treated animals over time to determine whether gene transfer to the liver could produce a circulating enzyme capable of reaching and correcting affected tissues.

Why This Matters

This research matters because current enzyme replacement therapy does not always provide optimal clinical improvement for individuals living with Pompe disease. By studying gene therapy approaches that enable the body to produce its own supply of the missing enzyme, researchers aimed to better understand how long-term enzyme production might improve treatment outcomes and potentially reduce the need for repeated infusions.

If successful, this strategy could help establish the foundation for future gene therapy trials and contribute to the development of more durable treatment approaches for people living with Pompe disease.
