  Purpose

Gaucher disease is a lysosomal storage disorder resulting from a deficiency in the key enzyme beta-glucocerebrosidase (GCase). The enzyme deficiency is caused by genetic mutations, which can result in the production of misfolded GCase. AT2101 is designed to act as a pharmacological chaperone by selectively binding to the misfolded GCase and helping it fold correctly, which may restore GCase activity.

This study is being conducted to test the safety of AT2101 in patients with type 1 Gaucher disease already receiving enzyme replacement therapy (ERT). The study will involve six visits over a period of 7 weeks and will evaluate the safety of AT2101.

Primary Outcome Measures:
  • The primary objective of the study is to evaluate the safety of AT2101. [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The secondary objective of the study is to assess pharmacodynamic effects of AT2101, including beta-glucocerebrosidase (GCase), glucocerebroside (GlcCer), chitotriosidase, and pulmonary and activation regulated chemokine (PARC). [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]
