Project Title

Towards a [more] personalized treatment of patients with Pompe disease

Project Snapshot

In 2019, the AMDA awarded the Helen Walker Research Grant to researchers at Erasmus MC University Medical Center in Rotterdam, The Netherlands. The project, led by Dr. Nadine A.M.E. van der Beek, focused on understanding why patients with Pompe disease respond differently to enzyme replacement therapy (ERT).

Although ERT has significantly improved outcomes for many individuals with Pompe disease, patients often experience varying levels of benefit over time. By studying long-term clinical outcomes, treatment dosing strategies, and biological factors influencing therapy response, the research team aimed to better understand these differences and move toward more personalized treatment strategies for Pompe disease.

Research Objectives

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

1. Define long-term outcomes of enzyme replacement therapy

Researchers examined long-term clinical data to better understand how patients respond to ERT over many years and why responses differ among individuals.

2. Investigate dosing strategies and treatment targeting

The team studied whether higher dosing strategies or improved targeting of the therapeutic enzyme could enhance treatment effectiveness.

3. Improve international treatment guidelines

By integrating clinical data, laboratory research, and patient-reported outcomes, the project aimed to help inform improved guidelines for treatment timing and dosing in Pompe disease care.

Why This Matters

Pompe disease affects individuals differently, and responses to enzyme replacement therapy can vary widely. Some patients experience long-term stabilization, while others see reduced benefit over time. Understanding the factors that influence treatment response is essential for improving care.

This research helps move the field toward precision medicine in Pompe disease, where treatment strategies can be tailored to the needs of individual patients. Insights from this work may also inform the development of next-generation therapies currently being explored.

Improving outcome measures in late onset Pompe disease: Modified Rasch-Built Pompe-Specific Activity scale

Citation

Summary
This study evaluated and improved the Rasch-Built Pompe-Specific Activity (R-PAct) scale, a patient-reported tool used to measure how Pompe disease affects daily life activities. Using data from more than 500 patients across multiple countries, researchers confirmed that the modified 17-item scale reliably measures two key domains—mobility and activities of daily living. The updated scale provides a more accurate way to track disease progression and treatment outcomes in people with late-onset Pompe disease.

The impact of COVID-19 infection, the pandemic and its associated control measures on patients with Pompe disease

Theunissen MTM, van den Elsen RM, House TL, et al. The impact of COVID-19 infection, the pandemic and its associated control measures on patients with Pompe disease. Journal of Neurology. 2024;271:32–45.

Summary
This international study examined how COVID-19 infection and the broader pandemic affected people living with Pompe disease. Researchers surveyed 342 patients across 25 countries about infections, treatment disruptions, and the physical and emotional effects of pandemic restrictions. While most COVID-19 infections were mild and resolved within four weeks, many patients reported interruptions in medical care and some experienced disruptions in enzyme replacement therapy. The pandemic also affected mental health and feelings of isolation for many participants, highlighting the importance of maintaining consistent, patient-centered care during global health crises.
