Brief Summary:
The purpose of this study is to compare the effect of AT1001 (migalastat hydrochloride) versus placebo on kidney GL-3.

Condition or disease Intervention/treatment Phase
Fabry Disease Drug: migalastat hydrochloride Drug: Placebo Phase 3

Detailed Description:

This double-blind, randomized, placebo-controlled study will be conducted in 60 patients at approximately 40 sites worldwide. The study will consist of two stages and an open-label treatment extension phase:

Stage 1 includes a screening period of up to 2 months followed by a 6-month treatment period which will involve 4 visits to the clinic. Patients will be randomized in equal proportions to receive either AT1001 or placebo.

After completing the 6-month double-blind phase, all patients will enter Stage 2 of the study and receive AT1001 in an open-label manner. Stage 2 treatment will last for 6 months and will involve 4 visits to the clinic.

Subjects who complete both Stage 1 and Stage 2 of the study as scheduled may be offered the opportunity to participate in an open-label treatment extension phase with AT1001. The open-label treatment extension phase will last 12 months and will involve 2 visits to the clinic. A follow-up visit will be undertaken 1 month following completion or discontinuation from the open-label treatment extension. Subjects completing the 12 month open-label treatment extension and providing consent to enter a separate long term extension will not be required to complete this follow-up visit.

Study assessments will include clinical laboratory tests, 12-lead ECG, kidney biopsy, kidney function testing, echocardiography, and patient reported outcomes.
