Clinical Trial Alert: Phase 1/2 Study of AT845 in Late-Onset Pompe Disease

Researchers at Audentes Therapeutics, an Astellas company, are seeking individuals living with late-onset Pompe disease (LOPD) to participate in a phase 1/2 study to confirm safety and efficacy of the investigational drug AT845. This gene-replacement therapy may offer the benefit of long-term improvement of motor and respiratory function and quality of life in adults living with LOPD.

All participants will receive AT845 during this study. The gene-replacement therapy will be administered via a one-time intravenous infusion (slow injection and delivery into a vein) within a hospital setting.  

The duration of the study is approximately five to six-and-a-half years. Participants may experience an 18-month run-in period before receiving treatment with AT845. After treatment, there will be a core observation period of 48 weeks with scheduled visits and assessments, followed by visits every six months to assess safety for up to five years post-treatment. In total, the study will require approximately 23-39 scheduled visits, including an inpatient assessment of one to two days.

To be eligible, individuals must meet the following criteria:

• 18 years of age or older
• Documented clinical diagnosis of Pompe disease by genetic testing
• Received enzyme replacement therapy (ERT) with rhGAA for the previous ≥ 2 years
• On a stable standard dose (at least 20 mg/kg every 2 weeks) of ERT with rhGAA for at least the previous 6 months
• Upright FVC ≥ 30% of predicted normal value

Individuals may not be eligible to participate if previously or currently affected by another illness or receiving another treatment that might interfere with the ability to undergo safe testing.
