Amicus Therapeutics Announces Full-Year 2014

Financial Results and Corporate Updates

MAA Submission for Migalastat Monotherapy for Fabry Disease on Track

for Mid-2015 — FDA Meeting Scheduled in 1Q15 to Discuss U.S. Pathway

Next-Generation Pompe ERT Set to Enter Clinic in 2H15

CRANBURY, NJ, March 3, 2015 — Amicus Therapeutics (Nasdaq: FOLD), a biopharmaceutical company at the forefront of therapies for rare and orphan diseases, today announced financial results for the full-year ended December 31, 2014. The Company also provided program updates and reiterated full-year 2015 net cash spend guidance.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “Our vision at Amicus is very clear: to build one of the most significant and lasting global biotechnology companies in the world, focused on transformational treatments for people living with devastating rare diseases. We will achieve this vision with world-class science and clinical medicine. To augment these areas of expertise we are currently in the process of building a global commercial leadership team. We remain on track for a mid-year marketing application in Europe for migalastat monotherapy for Fabry disease and we look forward to an upcoming meeting with the FDA to discuss a path forward for an NDA submission for migalastat monotherapy in the United States. We continue to believe firmly that the totality of the data with this important new precision medicine-based therapy should be available to Fabry patients in the U.S. as soon as possible.  Finally, advancing our next-generation enzyme replacement therapy for people living with Pompe disease is a key priority and that important program remains on track.  Indeed, a busy and important set of activities are ahead for the Amicus team this year. We hope that success in these endeavors will enhance the lives of many people living with Fabry and Pompe diseases.”

Financial Highlights for Full Year Quarter Ended December 31, 2014

·                  Cash, cash equivalents, and marketable securities totaled $169.1 million at December 31, 2014 compared to $82.0 million at December 31, 2013.

·                  Total operating expenses increased to $69.9 million compared to $64.5 million for the full-year 2013 primarily due to increases in preclinical and clinical development costs on the Fabry monotherapy and Pompe programs.

·                  Net cash spend was $53.2 million, below the full-year 2014 guidance range of $54-59 million.

·                  Net loss was $68.9 million, or $0.93 per share, compared to a net loss of $59.6 million, or $1.16 per share, for the full-year 2013.

2015 Financial Guidance

Cash, cash equivalents, and marketable securities totaled $169.1 million at December 31, 2014 compared to $82.0 million at December 31, 2013. The Company’s balance sheet was strengthened during 2014 with a $40 million at-the-market (ATM) financing as well as a $103.5 million public offering. Amicus expects full-year 2015 net cash spend between $73 million and $83 million. The current cash position is projected to fund operations into 2017.

Program Highlights

Fabry Franchise

Amicus is preparing to submit marketing applications for the oral pharmacological chaperone migalastat HCl (“migalastat”) as a precision medicine, orally bioavailable monotherapy for Fabry patients who have amenable mutations. Positive Phase 3 data in both treatment-naïve and ERT-switch patients have shown that treatment with migalastat has resulted in reductions in disease substrate, stability of kidney function, reduction in cardiac mass, and a positive impact in patient-reported outcomes in patients with amenable mutations. These results were recently featured in an oral presentation and 4 posters at WORLDSymposium™ 2015 in February. For all other Fabry patients who do not have amenable mutations and cannot take monotherapy, Amicus is advancing migalastat in combination with ERT.

Anticipated 2015 Fabry Franchise Milestones:

·                  FDA meeting to review totality of migalastat monotherapy data and discuss regulatory approval pathway (1Q15)

·                  Migalastat monotherapy MAA submission (mid-2015)

·                  Initiation of longer-term Phase 2 study of oral migalastat co-administered with currently marketed ERTs (2H15)

·                  Internal development underway of next-generation ERT (bio-better Fabry ERT cell line for co-formulation with migalastat)

Next-Generation ERT for Pompe Disease (ATB200 + Chaperone)

Amicus is leveraging its biologics capabilities and CHART™ (Chaperone-Advanced Replacement Therapy) platform to develop a next-generation Pompe ERT. This ERT consists of a uniquely engineered recombinant human acid alpha-glucosidase (rhGAA) enzyme (designated ATB200) with an optimized carbohydrate structure to enhance uptake, administered in combination with a pharmacological chaperone to improve activity and stability. In preclinical studies, ATB200 demonstrated greater tissue enzyme levels and further substrate reduction compared to the current approved ERT for Pompe disease (alglucosidase alfa), which were further improved with the addition of a chaperone. Clinical studies of pharmacological chaperones in combination with currently marketed ERTs have established initial human proof-of-concept that a chaperone can stabilize enzyme activity and potentially improve ERT tolerability. An oral presentation and 2 posters highlighting these preclinical results were presented at WORLDSymposium 2015 in February.

Anticipated 2015 Pompe Program Milestones:

·                  Completion of GMP batch of ATB200 (1Q15)

·                  Completion of IND-enabling toxicology studies (mid-2015)

·                  Pre-IND meeting (mid-2015)

·                  Clinical study initiation (2H15)
