Amicus Therapeutics Announces First Quarter
2009 Financial Results

Company Remains on Track to Advance Amigal for Fabry Disease into Phase 3 in Second Quarter

CRANBURY, N.J., May 7, 2009 — Amicus Therapeutics (Nasdaq: FOLD) today announced financial results for the first quarter 2009.

On a reported basis calculated in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Amicus announced a net loss attributable to common stockholders of $0.55 per share ($0.46 per share on a non-GAAP basis) for the three months ended March 31, 2009. As of March 31, 2009, cash, cash equivalents, and marketable securities totaled $109 million.

“Our first quarter was highlighted by positive Phase 2 extension data and continued progress towards our final Phase 3 development plan for Amigal in Fabry Disease,” said John F. Crowley, Amicus’ President and CEO. “We look forward to announcing our final protocol over the upcoming weeks and starting the trial later this quarter.”

Clinical Program Updates

Amigal™ (migalastat hydrochloride) for the treatment of Fabry disease

In the first quarter of 2009, Amicus continued to work closely with the U.S. and E.U. regulatory authorities in an effort to finalize its Phase 3 development plan for Amigal. The Company remains on track to announce the final Phase 3 protocol intended to support U.S. approval and to initiate Phase 3 development of Amigal in the second quarter of 2009.

Additionally, in March 2009 at the American College of Medical Genetics (ACMG) 2009 Annual Meeting in Tampa, FL, the Company presented positive results from its Phase 2 extension study with Amigal.

Amicus reported that treatment with Amigal was generally well-tolerated, with no drug-related serious adverse events. The most common adverse events were headache, arthralgia and diarrhea.

Subjects identified as responders to Amigal at the completion of the Phase 2 studies continued to maintain elevated levels of the target enzyme (a-Gal A), as measured in white blood cells, and reduced levels of the target substrate (kidney GL-3), as measured in urine.

A reduction of GL-3 levels was also observed in interstitial capillary cells from kidney biopsies. Previously reported Phase 2 results indicated that little to no GL-3 was detected in these cells in most subjects prior to treatment with Amigal. The new data were obtained from the retesting of biopsies using an improved methodology.

Preliminary results from the evaluation of modified doses and a new dosing regimen were also presented.

Plicera™ (afegostat tartrate) for the treatment of Gaucher Disease

A Phase 2 clinical trial of the Company’s investigational drug Plicera is ongoing. This 6-month study is designed to evaluate safety and to demonstrate trends of efficacy, as measured by the standard endpoints in Gaucher disease. The Company expects to report the results late in the third quarter of 2009.

Amicus will continue to work closely with its partner, Shire HGT, to prepare for Phase 3 development of Plicera pending the results of the ongoing Phase 2 trial.

Furthermore, during the first quarter, the Company announced the issuance of United States Patent No. 7,501,439, titled “Tartrate Salt of Isofagomine and Methods of Use.” The patent covers the tartrate salt form of isofagomine, the active ingredient in the Plicera, and its use for the treatment of Gaucher disease. The patent will expire in 2027.

AT2220 (1-deoxynojirimycin HCl) for the treatment of Pompe Disease

As previously reported, the Company suspended enrollment for the Phase 2 clinical trial of its investigational drug AT2220 for the treatment of Pompe Disease and received notice from the U.S. Food and Drug Administration (FDA) that the trial is on clinical hold.

The Company is currently evaluating all data and continues to work closely with the FDA to determine appropriate next steps for advancing the development of AT2220.

The events have no impact on Amicus’ ongoing studies with Amigal™ for Fabry disease and Plicera™ for Gaucher disease.

Preclinical Chaperone Programs

Amicus continues to invest in research and development to assess the potential for applying its versatile chaperone technology platform to the treatment of a broader range of human genetic diseases. As part of this effort, Amicus continues to conduct preclinical studies in Parkinson’s disease and is investing in new research aimed at evaluating disease targets for other neurodegenerative and genetic disorders.

Shire HGT Collaboration

In November 2007, Amicus entered into a strategic collaboration with Shire Human Genetic Therapies, Inc., a wholly-owned subsidiary of Shire plc, to jointly develop Amicus’ three lead pharmacological chaperone compounds for lysosomal storage disorders, Amigal, Plicera and AT2220. Under the terms of the collaboration Shire will pay development and sales milestones up to a maximum of $390 million, and will also pay tiered, double digit royalties on net sales of the products. Shire also reimburses world-wide development costs on a 50/50 basis, and in return Shire received rights to commercialize these products outside of the U.S. while Amicus retains all rights to commercialize these products in the U.S. In addition, Amicus leads development operations through the end of Phase 2 clinical trials. The companies then share responsibility for Phase 3 clinical trial development leveraging Shire’s significant ex-US regulatory and clinical experience as well as its commercial infrastructure.

Additional Financial Results & Notes

On a reported basis, the net loss attributable to common stockholders for the three months ended March 31, 2009, was $12.5 million as compared to $7.7 million for the same period in 2008. On a non-GAAP basis, the net loss for the three months ended March 31, 2009, was $10.5 million as compared to $6.4 million in the same period in 2008.

Amicus recorded revenue during the first quarter of 2009 representing two different revenue streams from the Shire agreement. Upon signing the agreement, Amicus received an upfront payment of $50 million that will be recognized as revenue on a straight-line basis over 18 years from the date of the agreement. In the first quarter of 2009, Amicus recognized $0.7 million of the Shire upfront payment and $3.9 million of research revenue on reimbursed research and development costs.

The differences between U.S. GAAP and non U.S. GAAP financial results are itemized in Tables 2 and 3 and are primarily due to pre-tax stock compensation expense.

Use of Non-GAAP Financial Measures

Amicus’ “non-GAAP net loss” and “non-GAAP diluted net loss per common share” financial measures are defined as reported, or GAAP, net loss and diluted net loss per common share excluding certain items further discussed below. Amicus’ management uses these non-GAAP financial measures to establish financial goals and to gain an understanding of the comparative financial performance of Amicus from year to year and quarter to quarter. Accordingly, Amicus believes investors’ understanding of Amicus’ financial performance is enhanced as a result of disclosing these non-GAAP financial measures. Non-GAAP net loss and diluted net loss per common share should not be viewed in isolation or as a substitute for reported, or GAAP net loss and diluted net loss per common share.

(1)

Stock option expense — Non-GAAP net loss and diluted net loss per common share exclude the impact of the stock option expense recorded in accordance with SFAS No. 123R. Amicus believes that excluding the impact of expensing stock options better reflects the recurring economic characteristics of its business.

Words such as, but not limited to, “look forward to,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “targets,” “likely,” “will,” “would,” “should” and “could,” and similar expressions or words identify forward-looking statements. Such forward-looking statements are based upon current expectations that involve risks, changes in circumstances, assumptions and uncertainties. The inclusion of forward-looking statements should not be regarded as a representation by Amicus that any of its plans will be achieved. Any or all of the forward-looking statements in this press release may turn out to be wrong.

For example, with respect to statements regarding the goals, progress, timing and outcomes of ongoing discussions with regulatory authorities and the potential goals, progress, timing and results of clinical trials, actual results may differ materially from those set forth in this release due to the risks and uncertainties inherent in the business of Amicus, including, without limitation: the potential inability to reach final agreement with regulatory agencies on the phase 3 trial design for Amigal; the potential that results of clinical or pre-clinical studies indicate that the product candidates are unsafe or ineffective; and, our dependence on third parties in the conduct of our clinical studies. Further, the results of earlier clinical trials may not be predictive of future results. Additionally, with respect to statements regarding projections of the Company’s cash position and expected use of cash during 2009, actual results may differ based on market factors, the company’s ability to execute its operational and budget plans, and its achievement of milestones and receipt of milestone payments from Shire.
