Amicus Therapeutics Announces First
Quarter 2008 Financial Results

Strong financial position supports clinical focus on advancing drug candidates
for treatment of lysosomal storage disorders

Cranbury, NJ, May 13, 2008— Amicus Therapeutics (Nasdaq: FOLD), a biopharmaceutical company developing small molecule, orally-administered pharmacological chaperones for the treatment of human genetic diseases, today announced financial results for the first quarter of 2008. 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 $0.34 per share ($0.28 per share on a non-GAAP basis) for the three months ended March 31, 2008. As of March 31, 2008, cash, cash equivalents, and marketable securities totaled $154.6 million.

“In the first quarter of 2008, we continued to advance our three lead clinical development programs. We also reported data from multiple clinical trials that add to the growing body of evidence demonstrating that treatment with our oral pharmacological chaperone drug candidates has the potential to benefit patients with Fabry, Gaucher and Pompe disease,” said John F. Crowley, President and CEO of Amicus Therapeutics. “In the months ahead in 2008, we will be focused on advancing the global regulatory plan for Amigal Phase 3 development, evaluating opportunities for additional clinical studies in Gaucher and Pompe disease, as well as on identifying new therapeutic areas for applying our pharmacological chaperone technology platform.”

Program Advancements

Fabry Disease:

Amigal™ (migalastat hydrochloride) is an investigational, oral therapeutic being developed for the treatment of Fabry disease. In March, clinical investigators presented positive results from Phase 2 clinical trials of Amigal at the American College of Medical Genetics (ACMG) meeting. The data showed that Amigal was generally safe and well-tolerated at all doses evaluated and no drug-related serious adverse events were reported. In addition, Amigal increased the level of the enzyme deficient in Fabry patients in 24 of 26 study subjects and in a majority of study subjects the treatment resulted in a reduction of kidney GL-3 as measured in urine.

Amicus, along with its partner Shire, has initiated discussions with the U. S. Food and Drug Administration (FDA) and the European Medicines Agency (EMEA) regarding its plans for Phase 3 clinical evaluation of Amigal. Amicus expects to complete these interactions and provide an update in the second half of 2008, and subject to the outcome of the discussions, the Company plans to initiate the Phase 3 clinical trial in the first half of 2009.

In parallel with the regulatory process, 23 of the original 26 patients continue to be treated with Amigal in the voluntary Phase 2 extension study to monitor long term safety and efficacy. In addition, the Company will evaluate modified doses and dose regimens in these 23 patients. Data from this extension study are expected to be available by Q1 2009, prior to finalization of the Phase 3 protocol.

Gaucher Disease:

Plicera™ (isofagomine tartrate) is an investigational, oral therapeutic being developed for the treatment of Gaucher disease. At the ACMG meeting in March, clinical investigators presented full data from a 4 week

Phase 2 study in Gaucher patients who switched from enzyme replacement therapy (ERT) with imiglucerase to the pharmacological chaperone Plicera. Results showed that Plicera was generally safe and well tolerated at all doses and increased target enzyme activity levels in a majority of patients. In the trial, GCase activity, as measured in white blood cells, was increased in 20 of the 26 patients with evaluable GCase data, and 5 of the 6 patients without a clear increase were either in the lowest dose cohort or the cohort dosed least frequently. As expected in this short term study, the levels of relevant hematological markers of Gaucher disease remained stable.

Amicus has amended the protocol for the 6-month Phase 2 clinical trial of Plicera patients naive to ERT to include modified doses and dose regimens. Amicus expects the results of this study to be available in 2009. In addition, in the second half of 2008, the Company expects to initiate a longer-term study in individuals switching from ERT to Plicera.

Pompe Disease:

AT2220 (1-deoxynojirimycin HCl) is an investigational, oral therapeutic drug candidate being developed for the treatment of Pompe disease. At the ACMG meeting in March clinical investigators presented encouraging results from an ex vivo response study in cells from patients with Pompe disease as well as three Phase 1 clinical trials of AT2220 in healthy volunteers. The ex vivo response study was designed to test the effect of AT2220 on various Pompe mutations. Blood and skin samples were collected from 30 Pompe patients (26 adults, 3 juveniles and 1 infant) with a variety of different mutations in acid alpha-glucosidase (GAA), the target enzyme in Pompe disease. Cells from these samples where then treated with AT2220. Of the 26 patients with available data, 24 had cells that showed a dose responsive increase in GAA levels including 22 patients who had at least 1 copy of the common splice site mutation IVS1-13T>G. Data from the Phase 1 trials in a total of 72 healthy volunteers showed that AT2220 was generally safe and well tolerated at all doses.

In the second quarter of 2008, Amicus plans to initiate a Phase 2 clinical trial of AT2220 in patients with Pompe disease. The Company also plans to consider the initiation of a clinical trial of AT2220-ERT combination treatment in Pompe patients later in 2008.

Other Chaperone Programs:

Amicus is accelerating its investment in research and development to assess the potential for using pharmacological chaperones to treat a broader range of human genetic diseases beyond lysosomal storage diseases. As part of this effort, Amicus continues to conduct preclinical studies in Parkinson’s disease, funded in part by a grant from the Michael J. Fox Foundation. In addition to the work in Parkinson’s, Amicus is investing in new research aimed at evaluating disease targets for other neurodegenerative disorders and metabolic disorders.

Shire Collaboration:

In November 2007, Amicus entered into a strategic collaboration with Shire Human Genetic Therapies (HGT), a business unit of Shire plc, to jointly develop Amicus’ three lead pharmacological chaperone compounds for lysosomal storage disorders, Amigal, Plicera and AT2220. In this collaboration valued at up to $440 million including an up front payment and success based clinical and sales milestones and excluding royalties and cost sharing, Shire also reimburses worldwide development costs on a 50/50 basis. Under the agreement, Shire received rights to commercialize these products outside of the United States. Amicus retains all rights to commercialize these products in the United States. Amicus will lead development operations through the end of Phase 2 clinical trials. The companies will 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, 2008, was $7.7 million as compared to $9.7 million for the same period in 2007. On a non-GAAP basis, the net loss for the three months ended March 31, 2008, was $6.4 million as compared to $8.9 million and the same period in 2007.

Amicus recorded revenue during the first quarter of 2008 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 2008, Amicus recognized $0.7 million of the Shire upfront payment and $2.5 million of research revenue on reimbursed research and development costs.

Amicus today reiterated its guidance for 2008 cash burn of $40 million to $60 million. The Company also stated that it does not expect to raise cash from any equity financings in 2008.

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

• Pre-tax charges for preferred stock accretion

• Pre-tax charges for changes in the fair value of warrant liability

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.

(2) Other items — Non-GAAP net loss and diluted net loss per common share exclude other unusual or non-recurring items that are evaluated on an individual basis. Amicus’ evaluation of whether to exclude an item for purposes of determining its non-GAAP financial measures considers both the quantitative and qualitative aspects of the item, including, among other things (i) its size and nature, (ii) whether or not it relates to its ongoing business operations, and (iii) whether or not Amicus expects it to occur as part of its normal business on a regular basis. Items excluded for purposes of determining non-GAAP net loss and diluted net loss per common share include deemed dividends, preferred stock accretion, and changes in the fair value of warrant liability.
