Amicus Therapeutics Announces Third Quarter 2012 Financial Results & Corporate Updates

6-Month Results Expected 4Q12 and 12-Month Results Anticipated 1H13 from Phase 3 Fabry Monotherapy Study 011

Additional Human Proof-of-Concept Demonstrated for Chaperone-Enzyme

Replacement Therapy (ERT) Combination Platform

CRANBURY, NJ, US, November 5, 2012 — Amicus Therapeutics (Nasdaq: FOLD), a biopharmaceutical company at the forefront of developing therapies for rare and orphan diseases, today announced financial results for the third quarter ended September 30, 2012. The Company also summarized recent and upcoming milestones and reiterated full-year 2012 operating expense guidance.

Key Highlights and Upcoming Milestones

·                  6-month primary endpoint results expected 4Q12 and 12-month data anticipated 1H13 from first Phase 3 Fabry monotherapy study (Study 011)

·                  Achieved target enrollment in Second Phase 3 Fabry monotherapy study (Study 012)

·                  Announced updated results from Phase 2 extension study (Study 205) to evaluate investigational migalastat HCl monotherapy

·                  Completed enrollment in Phase 2 Study 013 to investigate migalastat HCl co-administered with ERT - updated results to be presented at American Society of Human Genetics (ASHG) on November 8, 2012

·                  Announced positive Pompe program updates - additional preliminary results for AT2220-ERT co-administration from Phase 2 Study 010 and ex vivo studies on ERT-related immunogenicity — Study 010 results from all 4 cohorts anticipated 4Q12

John F. Crowley, Chairman and Chief Executive Officer of Amicus stated, “The third quarter 2012 was excellent for Amicus. We continued to demonstrate our operational excellence in global clinical research in rare and orphan diseases through our advancement of multiple Phase 2 and Phase 3 studies in Fabry and Pompe disease. We are especially pleased with the recruitment success in our second Phase 3 Fabry Study 012. Finally, further clinical and preclinical proof-of-concept evaluating the direct combination of pharmacological chaperones with ERTs to both enhance ERT stability and reduce ERT immunogenicity will be a cornerstone of our pipeline and shareholder value going forward.”

3Q12 Financial Results

The Company’s third quarter 2012 financial statements reflect updated revenue recognition accounting in conjunction with the expanded GSK collaboration (entered in July 2012). Payments received from GSK under the agreement are now being recorded in the “deferred reimbursements” account on the balance sheet. On September 30, 2012, the deferred reimbursements balance was $27.2 million. This amount included $4.5 million in cash reimbursed for shared global development costs of migalastat HCl during the third quarter 2012, and the $22.7 million unrecognized balance of the upfront license payment and premium on equity. Prior to July 1, 2012, quarterly cash reimbursements were recognized as “research revenue” and the upfront payment was amortized each quarter in “collaboration revenue.”

For the three months ended September 30, 2011, Amicus reported total revenue of $5.8 million, including $4.1 million in research revenue and $1.7 million in collaboration revenue. More information on the updated revenue recognition accounting, which does not impact cash, will be contained in the Company’s Form 10-Q for the quarter ended September 30, 2012.

Total operating expenses for the third quarter 2012 totaled $16.9 million compared to $18.9 million in the year-ago period on lower research and development expenses. Net loss attributable to common stockholders in the third quarter 2012 was $16.3 million, or $0.34 per share, compared to a net loss of $9.8 million, or $0.28 per share, in the year-ago period. The wider net loss versus the year-ago period is attributed to the change in revenue recognition under the expanded GSK collaboration.

Financial Guidance

Cash, cash equivalents, and marketable securities totaled $106.2 million at September 30, 2012 compared to $95.8 million at June 30, 2012 and $55.7 million at December 31, 2011. The current cash position reflects an $18.6 million equity investment from GSK related to the expanded collaboration and a $3.5 million cash milestone payment received from GSK in the third quarter 2012. Amicus expects to end 2012 with at least $90 million in cash, cash equivalents and marketable securities which is expected to fund its current operating plan beyond 2013. This projection includes quarterly reimbursement from GSK for shared development costs for migalastat HCl.

Amicus continues to expect full-year 2012 operating expenses within the higher end of the previously disclosed guidance range of $37 million to $43 million, net of anticipated cost sharing under the expanded Fabry disease collaboration with GSK. Amicus and GSK are funding 25% and 75% of the development costs, respectively, for migalastat HCl monotherapy and co-administration for full-year 2012. During the second half of 2012, Amicus and GSK will be responsible for 40% and 60% of the preclinical development costs, respectively, for the co-formulated chaperone-ERT product. Amicus will be responsible for all U.S. commercial activities for migalastat HCl upon approval, including pricing, marketing, patient access and reimbursement.

Program Updates

Amicus and GSK are co-developing all formulations of migalastat HCl under a global Fabry collaboration. Amicus has commercial rights to all Fabry products in the United States and GSK has commercial rights to all of these products in the rest of world. Outside the GSK collaboration, Amicus owns exclusive rights to the rest of its pipeline and applications of its platform technology.

Migalastat HCl Monotherapy for Fabry Disease

Migalastat HCl monotherapy is in Phase 3 development (Study 011 and Study 012) for Fabry patients with genetic mutations that are amenable to this chaperone monotherapy, as determined by a cell-based assay. Both studies are investigating oral migalastat HCl monotherapy 150 mg, dosed every-other-day (QOD).

Study 011 is a randomized, placebo-controlled study. During the fourth quarter 2012, Amicus and GSK expect to announce the primary endpoint analysis, based on interstitial capillary globotriaosylceramide (GL-3) as measured in kidney biopsy at 6 months. Results from the 6-month follow-up period in Study 011 are expected in the first half of 2013, which will include 12 months on migalastat HCl in the treatment group and 6 months on migalastat HCl in the placebo-crossover group.

Study 012 is the first clinical study to compare oral migalastat HCl to standard-of-care ERTs (Fabrazyme® and Replagal®). The open-label study randomized males and females with Fabry disease, who either to switch to migalastat HCl or remain on ERT. Amicus and GSK achieved target enrollment in Study 012 ahead of schedule. The primary outcome measure is renal function assessed by Glomerular Filtration Rate (GFR) at 18 months.

Amicus and GSK also continue to evaluate patients who completed a previous Phase 2 study in an ongoing Phase 2 extension study (Study 205) of migalastat HCl. Updated results from Study 205 were presented at the American Society of Nephrology (ASN) Kidney Week 2012. A total of 17 patients completed Study 205 after a median treatment duration of 5.2 years (4.7 to 6.4 years) with migalastat HCl in the Phase 2 and Phase 2 extension studies. 16 of these patients are currently enrolled in a separate open-label extension study (MGM116041).

Migalastat HCl in Combination with ERT for Fabry Disease

During the third quarter 2012, Amicus and GSK completed enrollment in an open-label Phase 2 study (Study 013) to investigate the effects of a single oral dose of migalastat HCl (150 mg or 450 mg) co-administered prior to ERT (Fabrazyme or Replagal) in 23 males with Fabry disease. Positive preliminary results were announced in the first quarter 2012 and updated data will be presented at the American Society of Human Genetics (ASHG). Amicus and GSK, along with GSK’s collaborator JCR Pharmaceutical Co. Ltd, also continue to advance preclinical studies of migalastat HCl co-formulated with JCR Pharmaceutical Co. Ltd’s proprietary investigational ERT (JR-051, recombinant human alpha-Gal A enzyme).

AT2220-ERT Co-Administration for Pompe Disease

In October 2012, Amicus announced additional positive preliminary results from a Phase 2 open-label study (Study 010) to investigate four ascending dose cohorts of the pharmacological chaperone AT2220 co-administered with ERT (Myozyme® and Lumizyme®) for Pompe disease. In the first 3 dose cohorts, AT2220-ERT co-administration increased Pompe enzyme (recombinant GAA) activity. Study 010 is fully enrolled and results from Cohort 4 are anticipated by year-end. In parallel with Study 010, initial ex vivo studies completed using T cells from 50 healthy donor blood samples demonstrated that the addition of AT2220 may reduce the immunogenicity of Myozyme and Lumizyme. Results from these studies may help guide further investigation of the effects of AT2220 on immune response to ERT in future clinical studies.

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 human genetic diseases. Amicus’ late-stage programs for lysosomal storage disorders include migalastat HCl monotherapy in Phase 3 for Fabry disease; migalastat HCl co-administered with enzyme replacement therapy (ERT) in Phase 2 for Fabry disease; and AT2220 co-administered with ERT in Phase 2 for Pompe disease.

About Migalastat HCl for Fabry Disease

Amicus and GSK are co-developing all formulations of migalastat HCl under a global Fabry collaboration. Amicus has commercial rights to all Fabry products in the United States and GSK has commercial rights to all of these products in the rest of world. As a monotherapy, migalastat HCl is designed to bind to and stabilize, or “chaperone” alpha-galactosidase A (alpha-Gal A) enzyme in patients with genetic mutations that are amenable to this chaperone in a cell-based assay. For patients currently receiving ERT for Fabry disease, migalastat HCl in combination with ERT may improve ERT outcomes by keeping the infused alpha-Gal A enzyme in its properly folded and active form.

Fabry disease is an inherited lysosomal storage disease 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.

About AT2220 for Pompe Disease

AT2220 is an investigational, orally-administered pharmacological chaperone owned exclusively by Amicus. In published preclinical studies, AT2220-ERT co-administration resulted in significant increases in muscle rhGAA levels and decreases in glycogen levels in a mouse model of Pompe disease. Preclinical results to date also suggest that AT2220-ERT co-administration may mitigate ERT-induced immunogenicity by stabilizing the enzyme in its properly folded and active form.

Pompe disease is a lysosomal storage disease characterized by progressive skeletal muscle weakness and respiratory insufficiency. It is caused by a deficiency in GAA activity, which leads to accumulation of glycogen in tissues affected by the disease (primarily muscle). Pompe disease affects an estimated 5,000 to 10,000 individuals worldwide and is clinically heterogeneous in the age of onset, the extent of organ involvement, and the rate of progression.
