Summary

"This trial is studying the safety and effectiveness of a single dose of AMT-191 given intravenously. They will test two different doses on groups of 3-6 participants each and monitor them

Who is the study for?

This trial is for men aged 18-50 with classic Fabry Disease, showing minimal GLA enzyme activity or a specific genetic variant. Participants must have moderate to severe gastrointestinal symptoms and persistent neuropathic pain. They should have an eGFR indicating moderate kidney function and weigh ≤80 kg. Candidates must agree to vaccination requirements and use condoms for 18 months post-dosing.

What is being tested?

The study tests AMT-191's safety, how it affects the body (PK/PD), and potential benefits in treating Fabry Disease over two years. It involves two groups receiving different doses of AMT-191 intravenously while continuing their regular enzyme replacement therapy.

What are the potential side effects?

Specific side effects are not listed but will be monitored throughout the study following administration of AMT-191. These may include reactions related to infusion, changes due to pharmacokinetics/pharmacodynamics assessments, or other unforeseen responses.
