Brief Summary
This study is a 12-month open-label extension (OLE) study of AT-007 in adult subjects with CG who previously participated in Study AT-007-1001 Part D and/or Part D Extension. The study is designed to assess the long-term safety of AT-007 in subjects with CG as well as the pharmacodynamics (PD) (inhibition of galactitol) and PK of AT-007. The effect of 12-month treatment with AT-007 on the levels of galactose and other galactose metabolites in subjects with CG will also be evaluated.
