A Phase 1b Study of Adenylosuccinic Acid (ASA-001) for Adenylosuccinate Synthase 1 (ADSS1) Deficient Myopathy.

Summary

The goal of this clinical trial is to evaluate the safety, tolerability and preliminary efficacy of ASA-001 in two adults diagnosed with ADSS1 deficient myopathy. The main questions it aims to answer are: * Whether ASA-001 can be safely administered to ADSS1 deficient myopathy patients; * Whether daily treatment with ASA-001 provides benefit or slows progression of disease.
