Conference Call and Webcast Today at 8:30am ET

CRANBURY, N.J., Nov. 05, 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 third quarter ended September 30, 2018. The Company also summarized recent program updates, reiterated its full-year 2018 revenue guidance and reduced its net cash spend guidance for the year.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc. stated, “The third quarter marked a major transformation for Amicus that brings us several steps closer toward our 2023 vision to treat at least 5,000 patients and to achieve $1 billion in annual global revenue. In the last three months, we received our first U.S. drug approval for Galafold, expanded our pipeline to include 14 new gene therapy programs for rare metabolic diseases, and presented positive 18-month data for our differentiated Pompe treatment paradigm. With a strong revenue base and $500M+ peak sales opportunity for Galafold, as well as $564 million in cash, we have never been in a stronger position to advance our robust portfolio to drive significant value for shareholders and the patient communities that we serve.”

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

“We are very pleased with the momentum of the global Galafold launch,” said Bradley L. Campbell, President and Chief Operating Officer of Amicus Therapeutics. “We see continued strong uptake and growth, along with very high compliance and adherence to this new oral Fabry treatment option, in both patients who are ERT-experienced and an increasing number who are ERT-treatment naïve in Europe. As anticipated, quarter-over-quarter revenue reflect some uneven ordering patterns as well as a rising number of extended, 90-day prescriptions as we headed into the summer months, which have normalized since the start of the fourth quarter. These adoption trends may reflect the emerging Fabry treatment paradigm with a stable oral medication that can be taken during summer travels and on holidays. Japan is also off to a solid start, now with a double-digit number of patient prescriptions. Importantly, the first 12 weeks of the U.S. launch have significantly exceeded our expectations. With more than 100 individual prescriptions for Galafold in the U.S., we are seeing robust patient demand from a broad prescriber base of more than 40 Fabry physicians. Given this global momentum, we are confident in meeting the higher end of our full-year 2018 guidance and setting a solid foundation for 2019.”

2018 Financial Guidance

For the full-year 2018 the Company reiterated its total Galafold revenue guidance to $80 to $90 million. This reflects global revenue from all expected 2018 commercial markets. The Company is lowering its full-year 2018 net cash spend to $190 to $210 million from the previous range of $220 to $250 million. The current cash position, including Galafold revenues, is sufficient to fund ongoing operations into at least 2021. Potential future business development collaborations, pipeline expansion, and investment in manufacturing capabilities could impact the Company’s future capital requirements.

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. 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:

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.

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 studies and the upcoming 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.

Recent and Anticipated AT-GAA Program Milestones:

As part of the Company’s long-term commitment to provide multiple solutions to address the significant unmet needs of the Pompe community, Amicus is also advancing a next-generation gene therapy as a potential cure for Pompe disease.

Gene Therapy Portfolio: 14 New Programs for Rare Metabolic Diseases
During the third quarter and early fourth quarter, Amicus expanded its pipeline [link here] to include 14 new gene therapy programs and future growth platform for rare metabolic diseases. The Company acquired 10 preclinical and clinical stage adeno associated virus (AAV) programs (intrathecal delivery) for neurologic lysosomal storage disorders (LSDs) currently in development at Nationwide Children’s Hospital. In collaboration with the University of Pennsylvania, the Company is advancing four next-generation AAV gene therapies for Fabry disease, Pompe disease, CDKL5 deficiency disorder (CDD) and one additional undisclosed rare metabolic disorder.

About Galafold 
GalafoldTM (migalastat) 123 mg capsules is an oral pharmacological chaperone of alpha-Galactosidase A (alpha-Gal A) for the treatment of Fabry disease in adults who have amenable GLA variants. In these patients, Galafold works by stabilizing the body’s own dysfunctional enzyme so that it can clear the accumulation of disease substrate. Globally, Amicus Therapeutics estimates that approximately 35 to 50 percent of Fabry patients may have amenable GLA variants, though amenability rates within this range vary by geography. Galafold is approved in Australia, Canada, European Union, Israel, Japan, South Korea, Switzerland and the U.S.

U. S. INDICATIONS AND USAGE
Galafold is indicated for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene (GLA) variant based on in vitro assay data.

This indication is approved under accelerated approval based on reduction in kidney interstitial capillary cell globotriaosylceramide (KIC GL-3) substrate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

U.S. IMPORTANT SAFETY INFORMATION

ADVERSE REACTIONS
The most common adverse reactions reported with Galafold (≥10%) were headache, nasopharyngitis, urinary tract infection, nausea and pyrexia.
