260+ Fabry Patients on Reimbursed Galafold™ (Migalastat) and
On Target to Reach 300 Patients by Year-End 2017

U.S. NDA Submission for Migalastat Planned in 4Q17

Pompe Retrospective and Prospective Data Collection Studies Initiated

Additional Pompe Clinical Data to be Presented at WORLDSymposium™ in February 2018

CRANBURY, N.J., Nov. 08, 2017 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq:FOLD), a global biotechnology company at the forefront of therapies for rare and orphan diseases, today announced financial results for the third quarter ended September 30, 2017. The Company also summarized recent program updates and reiterated full-year 2017 financial guidance.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, stated, "During the third quarter we continued to successfully execute across our strategic priorities for our core programs in Fabry and Pompe. We are pleased with the significant growth and expansion of our international Galafold launch, and the number of patients treated with this precision medicine for Fabry disease. In Pompe disease, the data cascade for our novel treatment paradigm ATB200/AT2221 has continued to exceed our expectations in terms of the consistency, durability and magnitude of effect across patients and across functional outcomes, key disease biomarkers and safety. There has been extraordinary patient and physician demand for this important potential treatment option. We are committed to increasing access to this investigational medicine for as many people as possible living with Pompe as soon as we can."

Amicus is on track to achieve four key strategic priorities between now and the end of 2017:

1)  Target of 300 patients on reimbursed Galafold;
2)  New Drug Application (NDA) submission for migalastat to the U.S.FDA;
3)  Continued advancements with the Pompe program, including now ongoing collaborative discussions with regulators to determine the best and fastest pathway; and
4)  A strong balance sheet with more than 18 months of cash at year-end.

Third Quarter 2017 Financial Results

• Total revenue in the third quarter 2017 was approximately $10.9 million, a sequential increase of 51.4% from total revenue of $7.2 million in the second quarter 2017, and a year-over-year increase of 419% from total revenue of $2.1 million in the third quarter 2016. Total revenue represents commercial sales of Galafold (migalastat) which commenced in May 2016, as well as reimbursed Expanded Access Programs (EAPs).
• Cash, cash equivalents, and marketable securities totaled $426.6 million at September 30, 2017 compared to $330.4 million at December 31, 2016.
• Total operating expenses increased to $284.3 million compared to $46.7 million for the third quarter 2016 primarily from non-cash charges related to the Phase 3 ESSENCE study in epidermolysis bullosa (EB).
• Operating expenses, as adjusted, excludes the impact of the non-cash charges related to the ESSENCE study, were $73.5 million, representing a $26.8 million increase over the third quarter of 2016 primarily due to increased investments in the Pompe and EB programs as well as increased investment in the Galafold commercial launch.
• Net cash spend was $147.3 million for the nine months ending September 30, 2017.
• Net loss was $111.7 million, or $0.69 per share, compared to a net loss of $46.7 million, or $0.33 per share, for the third quarter 2016. Net loss, as adjusted excludes the impact of the non-cash charges related to the ESSENCE study was $65.6 million or $0.41 per share.

2017 Financial Guidance

Cash, cash equivalents, and marketable securities totaled $426.6 million at September 30, 2017 compared to $330.4 million at December 31, 2016. The current cash position includes $243.0 million in net proceeds from a follow on public offering in July 2017.

Amicus continues to expect full-year 2017 net operating cash spend of between $175 million to $200 million and full-year 2017 total net cash spend (including third-party milestone payments and capital expenditures) of between $200 million and $225 million. The current cash position is anticipated to fund ongoing operations into at least the second half of 2019.

Program Highlights

Migalastat for Fabry Disease

Migalastat is an oral precision medicine intended to treat Fabry disease in patients who have amenable genetic mutations. Regulatory authorities in the European Union, Switzerland, Israel, Canada and Australia have granted full approval for migalastat under the trade name Galafold. The EU approval may serve as the basis for regulatory approvals in more than two-thirds of the global Fabry market that is outside the U.S. In the U.S., as previously announced, the FDA has confirmed that Amicus may submit a new drug application (NDA) for migalastat.

International Launch and Expanded Access Programs (EAP) Updates:

• More than 260 patients (naïve and ERT-switch) on reimbursed Galafold as of October 31, 2017
• 13 countries with reimbursement (commercial or EAP) including the top four largest EU countries
• Reimbursement dossiers submitted and pricing discussions are now underway in 12 countries
• Target of 300 patients treated with reimbursed Galafold on track for year-end 2017

Global Regulatory Updates:

• Four additional approvals secured outside the EU (Switzerland, Israel, Canada and Australia)
• Regulatory submissions completed in seven additional countries outside the EU, including Japan
• NDA submission to U.S. FDA to be based on existing data on track for 4Q17

Anticipated Upcoming Fabry Disease Program Milestones:

• Commercial launch and EAPs in additional international countries
• Additional regulatory submissions including a U.S. NDA (4Q17)
• Regulatory decision in Japan (1H18)
• Final preclinical data and announcement of path forward for novel Amicus Fabry ERT cell line for Fabry patients with non-amenable mutations (1Q18)

ATB200/AT2221 for Pompe Disease

ATB200/AT2221 is a novel treatment paradigm that consists of ATB200, a unique recombinant human acid alpha-glucosidase (rhGAA) enzyme with optimized carbohydrate structures, particularly mannose-6 phosphate (M6P), to enhance uptake, co-administered with AT2221, a pharmacological chaperone. Additional positive data were reported in October 2017 from an ongoing global Phase 1/2 clinical study (ATB200-02) to evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of ATB200/AT2221 across three cohorts, including ambulatory ERT-switch patients (Cohort 1), non-ambulatory ERT-switch patients (Cohort 2), and ERT-naïve patients (Cohort 3). The Company has commenced collaborative discussions with U.S. and EU regulators regarding the best and fastest pathway forward for this novel treatment option, and continues to anticipate a Pompe regulatory pathway update in the first half of 2018.           

In order to continue to build a robust data set and to meet the needs of the Pompe community, Amicus announced the following four key status updates for this important program:

• A retrospective natural history study of Pompe patients treated with approved standard of care ERT has been initiated at leading global Pompe disease treatment centers (POM-002 Study)
• A prospective observational study has also been initiated in Pompe patients currently receiving approved standard of care ERT at leading global Pompe disease treatment centers (POM-003 Study)   
• All engineering runs successfully completed and GMP production of ATB200 has commenced at the large commercial scale (1,000 Liters)
• Analytical and in vivo (preclinical) comparability studies completed between the 250 Liter and 1,000 Liter scale 

Anticipated Upcoming Pompe Disease Program Milestones:

• Ongoing discussions with U.S. and EU regulators
• Additional data from ATB200-02 clinical study at 14^th Annual WORLDSymposium™ (February 5-9, 2018)
• Pompe regulatory pathway update (1H18)

SD-101 for Epidermolysis Bullosa (EB)

During the third quarter Amicus reported that top-line data from the randomized, double-blind, placebo-controlled Phase 3 clinical study (ESSENCE, SD-005) to assess the efficacy and safety of the novel topical wound-healing agent SD-101 did not meet the primary endpoints or secondary endpoints in participants with EB. Based on these top-line data Amicus has no current plans to invest in any additional clinical studies or commercial preparation activities for SD-101. The Company continues to make SD-101 available to all patients currently enrolled in the ongoing extension study (SD-006).

Non-GAAP Financial Measures
