NCT05418829

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.

    12 months

  • To evaluate the long-term safety of 12-month oral administration of AT-007 in adult subjects with CG as assessed by clinical laboratory test results.

    Number of participants with clinically-significant changes in clinical laboratory test results.

    12 months

  • To evaluate the long-term safety of 12-month oral administration of AT-007 in adult subjects with CG as assessed by physical exam parameters.

    Number of participants with clinically-significant changes in physical examination findings, vital sign abnormalities, and electrocardiogram findings.

    12 months

Secondary Outcomes (3)

  • To evaluate the long-term change of galactitol, a biomarker of AR activity, induced by 12-month oral administration of AT-007 to adult subjects with CG
