Exhibit 99.1

Amicus Therapeutics Announces First Quarter 2015 Financial Results and Corporate Updates

Marketing Submissions for Migalastat Monotherapy for Fabry Disease

on Track for 2Q15 in Europe and 2H15 in United States

Net Cash Spend Guidance Updated to $100-$110 Million

on Accelerated Commercialization and Manufacturing

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

CRANBURY, NJ, May 5, 2015 — Amicus Therapeutics (Nasdaq: FOLD), a biopharmaceutical company at the forefront of therapies for rare and orphan diseases, today announced financial results for the first quarter ended March 31, 2015. The Company also provided program updates and updated full-year 2015 net cash spend guidance as a result of the accelerated regulatory timelines for migalastat monotherapy for Fabry disease.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “During the first quarter we made significant progress in preparing to submit our initial marketing applications and in building our international infrastructure to support the global launch of migalastat monotherapy for people living with Fabry disease who have amenable genetic mutations. Accelerating our submission timeline in Europe moves up the potential EU launch of migalastat, so are we are updating our full-year net cash spend guidance to account for the pre-commercial activities that have shifted from 2016 to 2015. We are committed to making migalastat available and accessible to patients as quickly as possible. Our next-generation enzyme replacement therapy for people living with Pompe disease is also on track and advancing toward the clinic by the end of this year. Through our dedication to patient-centricity, world-class science and clinical medicine, we are laying the foundation to become a leading global biotechnology company focused on transformational treatments for people living with devastating rare diseases.”

Financial Highlights for First Quarter Ended March 31, 2015

·                  Cash, cash equivalents, and marketable securities totaled $151.6 million at March 31, 2015 compared to $169.1 million at December 31, 2014.

·                  Total operating expenses increased to $24.1 million compared to $16.1 million for the first quarter 2014 primarily due to increases in preclinical and clinical development costs on the Fabry monotherapy and Pompe ERT programs.

·                  Net loss was $24.3 million, or $0.25 per share, compared to a net loss of $15.9 million, or $0.25 per share, for the first quarter 2014.

2015 Financial Guidance

Cash, cash equivalents, and marketable securities totaled $151.6 million at March 31, 2015 compared to $169.1 million at December 31, 2014. As a result of the accelerating timeline for the marketing authorization application (MAA) submission for migalastat monotherapy for Fabry disease in Europe, which also moves up the timing of a potential commercial launch, Amicus now expects full-year 2015 net cash spend between $100 million and $110 million, up from the previous guidance range of $73 million to $83 million. The current cash position is projected to fund operations into the second half of 2016.

As previously announced in March of 2015, Amicus had positive meetings with regulatory authorities in Europe and the United States to discuss the approval pathway for migalastat monotherapy for Fabry disease. Following these meetings, Amicus accelerated the timeline for its MAA submission in Europe from the middle of 2015 to the second quarter of 2015, and disclosed plans to submit a new drug application (NDA) in the U.S. in the second half of this year.

Program Highlights

Fabry Franchise

Amicus is preparing to submit marketing applications globally for the oral pharmacological chaperone migalastat HCl (“migalastat”) as a precision medicine, orally bioavailable monotherapy for Fabry patients who have amenable mutations. The Company is building out its infrastructure in both the U.S. and Europe to support potential commercial launches in 2016.

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. 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:

·                  Migalastat monotherapy MAA submission in Europe (2Q15)

·                  Pre-NDA meeting with FDA and NDA submission for migalastat monotherapy in U.S. (2H15)

·                  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.

Anticipated 2015 Pompe Program Milestones:

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

·                  Pre-IND meeting (mid-2015)

·                  Clinical study initiation to investigate ATB200 + chaperone in Pompe patients (2H15)
