Conference Call and Webcast Today at 8:30am ET

CRANBURY, N.J., Aug. 07, 2018 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq: FOLD), a global biotechnology company focused on discovering, developing and delivering novel medicines for rare metabolic diseases, today announced financial results for the second quarter ended June 30, 2018. The Company also summarized recent program updates, raised its full-year 2018 revenue guidance and updated its net cash spend guidance for the year.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc. stated, “In the first half of 2018, we have made tremendous progress advancing Galafold, expanding access to patients with amenable mutations across the world. Given the continued strong momentum of the Galafold launch, the early commercial launch in Japan, and the pending accelerated approval in the U.S., we are raising our 2018 revenue guidance to $80 million to $90 million. We have also continued to advance our Pompe clinical, manufacturing and regulatory activities and look forward to providing an update later this quarter on the pivotal study design and best and fastest regulatory path in the United States for this important program. Additionally, we are also extraordinarily focused on assembling a portfolio of technologies, programs and partnerships in the gene therapy space. Our goal beginning in the second half of this year is a bold one: to build one of the most robust gene therapy pipelines in the field of rare, metabolic disorders. We are well positioned to achieve our vision to impact as many people as possible who are living with rare metabolic diseases as we continue to build a leading global rare disease biotech company.”

Second Quarter 2018 Financial Results and Full-Year 2018 Financial Guidance

• Total revenue in the second quarter 2018 was $21.3 million, a year-over-year increase of 198% from total revenue of $7.2 million in the second quarter of 2017.
• Cash, cash equivalents, and marketable securities totaled $552.8 million at June 30, 2018, compared to $358.6 million at December 31, 2017.
• Total operating expenses increased to $65.1 million for the second quarter 2018 compared to $53.2 million in the second quarter 2017, reflecting an increased investment in Pompe clinical and manufacturing activities as well as Galafold commercial launch and launch preparations.
• Net cash spend was $51.0 million for the second quarter 2018. Net loss was $61.8 million, or $0.33 per share, for the second quarter 2018 compared to a net loss of $48.1 million, or $0.34 per share, for the second quarter 2017.

“The second quarter of 2018 marked another period of continued growth for Galafold,” said Bradley L. Campbell, President and COO of Amicus Therapeutics. “We are raising our full-year 2018 Galafold global revenue guidance given the current and anticipated increase in patient and physician adoption in our existing markets, the ongoing launch in Japan, and our anticipated PDUFA date and launch in the U.S. this quarter.  And we’re pleased to announce that we’ve hired 100% of our US launch team comprised of passionate professionals with significant rare disease experience.”

2018 Financial Guidance

For the full-year 2018 the Company is increasing its total Galafold revenue guidance to $80 million to $90 million from the previous range of $75 million to $85 million. This reflects global revenue from all expected 2018 commercial markets. 

Based on the increase in expected 2018 revenue and operating expenses that are trending favorably to budget, the Company is updating its full-year 2018 net cash spend to $220 to $250 million from the previous range of $230 to $260 million. The current cash position, including proceeds from the February 2018 equity offering and expected Galafold revenues, is sufficient to fund ongoing Fabry and Pompe program operations into at least 2021. Potential future business development collaborations, pipeline expansion, and investment in biologics manufacturing capabilities could impact the Company’s future capital requirements.

Program Highlights

Migalastat for Fabry Disease
Amicus is committed to advancing the highest quality therapies for all people living with Fabry disease. Migalastat, the Company’s first therapy, is an oral precision medicine. Regulatory authorities in Australia, Canada, EU, Israel, Japan, South Korea and Switzerland have granted full approval for migalastat under the trade name Galafold to treat Fabry disease in patients 16 years or older who have amenable genetic mutations. In the U.S., the FDA accepted the Company’s new drug application (NDA) for migalastat under Subpart H priority review with a six-month PDUFA goal date of August 13, 2018.

For people with non-amenable mutations who are not eligible for migalastat as an oral precision medicine, the strategy is to advance next-generation therapies such as a novel Fabry ERT (ATB101) co-formulated with migalastat or other innovative technologies that continue to be evaluated.

Global Fabry Updates:

• Pricing and reimbursement secured in 19 countries with first commercial patients treated in multiple new countries in 2018
• Approvals secured in Australia, Canada, EU, Israel, Japan, South Korea and Switzerland
• Commercial launch initiated in Japan during the second quarter
• U.S. leadership and field team now in place to support planned U.S. launch

Anticipated Milestones:

• U.S. FDA regulatory decision (3Q18)

AT-GAA for Pompe Disease

AT-GAA 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 to stabilize ATB200 while in the circulation to deliver active therapeutic enzyme.

The Company is engaged in collaborative discussions with U.S. and EU regulators regarding a number of key topics including a registration-directed study for full approval, manufacturing activities, and the best and fastest pathway forward for this novel treatment regimen. The Company believes that the evolving regulatory paths in both the U.S. and EU will include a series of iterative discussions with regulators as the program advances and as additional data are collected, including data from existing patients in ongoing studies, data from new patients being enrolled into ongoing studies, and the results of a formal retrospective natural history study of Pompe patients receiving current standard of care ERT. Amicus expects to provide an FDA update in the third quarter 2018 after receipt of written minutes from a scheduled Type C meeting.

Manufacturing activities to support the needs of the Pompe community are also ongoing.

Pompe Manufacturing Updates:

• Release of 1,000L GMP material for use in the planned pivotal study.
• Feedback from German regulatory authorities (BfArM) indicating general agreement with the manufacturing strategy for ATB200, including the strategy to demonstrate comparability of drug substance and drug product between the 1,000 liter scale and the 250 liter scale.

Anticipated Pompe Program Milestones in 2H18:

• Pompe US regulatory update (3Q18).
• Completion of a retrospective natural history study in ~100 ERT-treated Pompe patients.
• 18-month data from ATB200-02 clinical study to be presented at the 23rd International Congress of the World Muscle Society (4Q18).
• Commence pivotal study in 2H18.
