Amicus Therapeutics Announces Close of Patient Recruitment in First Phase 3 Study of Amigal(TM) for Fabry Disease

Final Enrollment on Track for 4Q11

CRANBURY, N.J., Oct. 19, 2011 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq:FOLD), a biopharmaceutical company at the forefront of developing therapies for rare diseases, today announced that patient recruitment has closed in the first Phase 3 global registration study (Study 011) of Amigal™ (migalastat HCl) for Fabry disease. Participating sites have stopped screening new patients, and Amicus and its collaborator GlaxoSmithKline (GSK) continue to anticipate full enrollment this quarter upon initial dosing of the last patient.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics stated, "I am proud to announce that we, along with our collaborator GSK, have closed recruitment for the first phase 3 study for Amigal. This is a significant accomplishment given the strict entry criteria for Study 011. I am confident in the strength of our Fabry program and impressed with the coordinated effort at Amicus and GSK as we continue to progress."

Study Design

Study 011 is a six-month, placebo-controlled Phase 3 study of migalastat HCl for Fabry disease at 37 centers worldwide to support marketing applications for the U.S. Food and Drug Administration (FDA) and other regulatory agencies. The study is expected to randomize approximately 60 male and female Fabry patients, with an equal number to receive migalastat HCl 150 mg or placebo on an every-other-day (QOD) oral dosing schedule for a six-month treatment period.

Patients enrolled in the study must meet the following entry criteria: naïve to enzyme replacement therapy (ERT) or have not received ERT for at least six months, a genetic mutation that may be addressable with migalastat HCl, and elevated urine globotriaosylceramide (GL-3) levels at least four times the upper limit of normal.

About Amicus Therapeutics

Amicus Therapeutics (Nasdaq:FOLD) is a biopharmaceutical company at the forefront of developing therapies for rare diseases. The Company is developing orally-administered, small molecule drugs called pharmacological chaperones, a novel, first-in-class approach to treating a broad range of diseases including lysosomal storage disorders and diseases of neurodegeneration. Amicus' lead program Amigal™ (migalastat HCl) is in Phase 3 for the treatment of Fabry disease.

About Migalastat HCl

Migalastat HCl is an investigational, oral pharmacological chaperone in Phase 3 development for the treatment of Fabry disease. On October 29, 2010, Amicus announced a definitive agreement with GlaxoSmithKline (GSK) to develop and commercialize migalastat HCl. Under the terms of the agreement, GSK received an exclusive worldwide license to develop, manufacture and commercialize migalastat HCl.

Amicus and GSK are conducting two Phase 3 global registration studies (Study 011 and Study 012) of migalastat HCl monotherapy, along with a Phase 2 study (Study 013) evaluating migalastat HCl-ERT co-administration for the treatment of Fabry disease.

About Fabry Disease

Fabry disease is an inherited lysosomal storage disorder that is currently estimated to affect approximately 5,000 to 10,000 people worldwide. Fabry disease is caused by deficiency of an enzyme called alpha-galactosidase A (alpha-Gal A). The role of alpha-Gal A within the body is to break down a complex lipid called globotriaosylceramide (GL-3). Reduced or absent levels of alpha-Gal A activity leads to the accumulation of GL-3 in the affected tissues, including the central nervous system, heart, kidneys, and skin. This accumulation of GL-3 is believed to cause the various symptoms of Fabry disease, including pain, kidney failure, and increased risk of heart disorders and stroke.
