Clinical Trial Summary

This study was conducted to test the safety and tolerability of afegostat tartrate in participants with type 1 Gaucher disease already receiving enzyme replacement therapy.


Description:

This was a Phase 2, open-label study in participants with Gaucher disease, a lysosomal storage disorder. Afegostat tartrate (also known as AT2101 or isofagomine tartrate) is designed to act as a pharmacological chaperone by selectively binding to misfolded β-glucocerebrosidase (GCase) and helping it fold correctly, intended to restore GCase activity. The study consisted of a 14-day screening period, a 28-day treatment period, and a 7-day wash-out period. Participants received 1 of 4 dosing regimens for afegostat tartrate.

Outcome

Type Measure Description Time frame Safety issue
Primary Number Of Participants Who Experienced Severe Treatment-emergent Adverse Events (TEAEs) TEAEs were defined as any adverse event (AE) with a start date on or after administration of the study drug (on Day 1). A severe AE was defined as an AE that was incapacitating and required medical intervention. The number of participants who experienced 1 or more severe TEAEs after dosing on Day 1 through 7 days after the last dose of study drug (Day 35) is presented. A summary of serious and all other non-serious AEs regardless of causality is located in the Reported Adverse Events module. Day 1 (after dosing) through Day 35
Secondary Change From Baseline To End Of Treatment In Beta-glucocerebrosidase (GCase) Levels In White Blood Cells (WBC) GCase is a biomarker used to assess the PD effects of afegostat tartrate. Blood samples were collected to assess GCase levels in WBC. The baseline value was defined as the last non-missing value before the start of study drug. Baseline, Day 28
