CRANBURY, N.J., Jan. 07, 2019 (GLOBE NEWSWIRE) —  Amicus Therapeutics (Nasdaq: FOLD), a global biotechnology company focused on discovering, developing and delivering novel medicines for rare metabolic diseases, today provided unaudited preliminary Galafold revenue for the full-year 2018 and introduced its full-year 2019 strategic outlook and financial guidance.

During 2018 Amicus met or exceeded all five key strategic priorities:

• More than doubled global revenue for Galafold (migalastat). Revenue grew from $36.9 million in full-year 2017 to approximately $91 million (preliminary and unaudited) in full-year 2018, exceeding the high end of the full-year 2018 guidance range of $80 million to $90 million.
• Successfully secured approvals for migalastat in the U.S. and Japan, with strong initial adoption. As of December 31, 2018, 149 patients in the U.S. have been prescribed Galafold since the August launch.
• Achieved clinical, manufacturing and regulatory milestones to advance AT-GAA toward global regulatory submissions and approvals. Highlights included positive 12- and 18-month data from the ongoing Phase 1/2 clinical study, manufacturing scale up (1000L), and first patient dosed in the PROPEL pivotal study.
• Pipeline expanded to include 14 new gene therapy programs, including two clinical programs in Batten disease, exceeding target of least one new clinical program in 2019. Target enrollment has been achieved in the Phase 1/2 study in CLN6 Batten disease, and the first patient has been dosed in the Phase 1/2 study in CLN3 Batten disease.
• Maintained and strengthened the balance sheet. The current cash position of approximately $505 million (preliminary and unaudited) at December 31, 2018 is expected to fund ongoing operations into at least mid-2021.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc. stated, “During 2018 we advanced several steps closer to our 2023 vision to treat at least 5,000 patients and achieve $1 billion in global revenue. Following the new approvals for our Fabry precision medicine Galafold in the U.S. and Japan, and continued growth momentum in international markets, we have exceeded our 2018 guidance. Patients are also now being treated in multiple Amicus clinical studies, including our Phase 1/2 and pivotal studies of AT-GAA for Pompe disease, as well as Phase 1/2 studies of our investigational gene therapies for CLN3 and CLN6 Batten disease. Today we are in a stronger position than ever to become a leading global biotechnology company focused on transforming the lives of people living with these rare, life-threatening conditions and creating significant value for our shareholders.”

Amicus is focused on the following five key strategic priorities in 2019:

• Nearly double again annual revenue for Galafold (FY19 guidance of $160M-$180M in worldwide revenue) with 1,000+ Fabry patients on Galafold by year end
• Complete enrollment in pivotal study in Pompe disease and report additional Phase 2 data
• Report additional two-year results from Phase 1/2 clinical study in CLN6 Batten disease and complete enrollment in ongoing CLN-3 Batten disease Phase 1/2 study
• Establish preclinical proof of concept for Fabry and Pompe gene therapies
• Maintain a strong financial position

Mr. Crowley will discuss Amicus’ corporate objectives and key milestones in a presentation at the 37th Annual J.P. Morgan Healthcare Conference on Tuesday, January 8, 2019 at 8:30 a.m. PT (11:30 a.m. ET). A live webcast of the presentation can be accessed through the Investors section of the Amicus Therapeutics corporate web site at http://ir.amicusrx.com/events.cfm, and will be archived for 90 days.

Full-Year 2018 Financial Summary and 2019 Guidance

Amicus recorded approximately $91 million (preliminary and unaudited) in full-year 2018 revenue from commercial sales and reimbursed expanded access programs for Galafold. For the full-year 2019 the Company anticipates total Galafold revenue of $160 million to $180 million. Prescription growth in 2018 was largely driven by EU and other countries outside the U.S. and Japan. Growth in 2019 is expected to be driven by continued growth in EU markets, further geographic expansion, and further success from the first full year of launch in the U.S. and Japan.

Cash, cash equivalents, and marketable securities totaled just over $500 million (preliminary and unaudited) at December 31, 2018.  The Company expects to end 2019 with approximately $300 million in cash on hand. The current cash position is anticipated to fund ongoing operations into at least mid- 2021.

Program Highlights

Galafold (Migalastat) Oral Precision Medicine for Fabry Disease
Galafold is an oral precision medicine for Fabry disease approved in the EU and other geographies to treat Fabry disease in patients 16 years or older who have amenable genetic mutations. The U.S. FDA approved Galafold under Subpart H for the treatment of adult patients with a confirmed diagnosis of Fabry disease and an amenable genetic variant. An estimated 35% to 50% of the global Fabry population may be suitable for treatment with Galafold on the basis of their genetic mutations, or variants. For patients who are not suitable for treatment with Galafold on the basis of their genetic mutations, or variants, Amicus is advancing a next-generation gene therapy.

Global Galafold Updates:

• 650+ patients (naïve and ERT-switch) on reimbursed Galafold worldwide as of December 31, 2018.
• Approvals secured in eight geographies including Australia, Canada, EU, Israel, Japan, South Korea, Switzerland, and United States and pending in Taiwan and several additional markets.
• U.S. launch exceeded internal expectations with 149 new patient prescriptions, also known as patient referral forms (PRFs), as of December 31, 2018. Time to shipment was up to 60 days, limiting 2018 revenue impact but providing a strong foundation for 2019.
• Pricing and reimbursement secured in 24 countries.
• Registry and other Phase 4 supportive studies underway.

AT-GAA for Pompe Disease
AT-GAA is a novel treatment paradigm in Phase 3 development 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. Positive results from a global Phase 1/2 clinical study (ATB200-02) have shown consistent and durable responses across key measures of safety, functional outcomes and biomarkers in both ERT-switch and ERT-naïve Pompe patients following up to 18 months of treatment with AT-GAA.

The Company’s strategy is to enhance the body of clinical data for AT-GAA in ongoing clinical studies, including the pivotal study (PROPEL, also referred to as ATB200-03) to deliver this potential new therapy to as many people living with Pompe disease as soon as possible. Based on regulatory feedback from both the U.S. FDA and European Medicines Agency (EMA), the PROPEL study is expected to support approval for a broad indication, including ERT-switch and treatment-naïve patients.
Pompe Program Updates:

• 1000L scale material released for pivotal PROPEL study.
• Dosing initiated in PROPEL study.
• WuXi partnership strengthened with 5-year supply agreement.

Anticipated Pompe Program Milestones in 2019:

• New data from the Phase 1/2 ATB200-02 clinical study, including final 24-month data in Cohorts 1-3, and initial 6-month data in additional ERT-switch patients (Cohort 4).
• Retrospective natural history study data in approximately 100 ERT-treated Pompe patients.
• Additional supportive studies, including an open-label study in pediatric patients.
• Full enrollment in Phase 3 PROPEL study.
• Advance agreed upon CMC requirements to support BLA.

             
Gene Therapy Programs for Rare Metabolic Diseases
During the third quarter and early fourth quarter of 2018, Amicus expanded its pipeline and future growth platform [link here] to include 14 new gene therapy programs and future growth platform for rare metabolic diseases, including 10 preclinical and clinical stage adeno associated virus 9 (AAV9) programs (intrathecal delivery) for neurologic lysosomal storage disorders (LSDs). Together these 10 programs have the potential to address 10,000+ people living with these neurologic LSDs and represent a $1 billion recurring revenue opportunity. Amicus is also developing four next-generation AAV gene therapies for Fabry disease, Pompe disease, CDKL5 deficiency disorder (CDD) and one additional undisclosed rare metabolic disorder.

In Batten disease, compelling proof-of-concept has been demonstrated in preclinical studies in CLN6, CLN3, and CLN8, as well as initial clinical safety and efficacy in a Phase 1/2 study in patients with CLN6. The Company has also shown early proof-of-principle for Amicus DNA constructs for optimized gene therapies for Fabry and Pompe diseases.

Gene Therapy Program Updates:

• First patient treated in CLN3 Batten disease Phase 1/2 study with no serious adverse events reported to date.
• Target enrollment achieved in CLN6 Batten disease Phase 1/2 study, with 12 patients receiving a single administration of gene therapy (exposure ranging from ~1 to 34 months).

Anticipated Gene Therapy Pipeline Milestones in 2019:

• Additional two-year data from CLN6 Batten disease Phase 1/2 study.
• Full enrollment of ongoing CLN3 Batten disease Phase 1/2 study.
• Preclinical data for next-generation gene therapies for Fabry, Pompe and CDD.
• Preclinical work across additional neurologic LSDs.
