PHILADELPHIA, March 01, 2021 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq: FOLD), a patient-dedicated global biotechnology company focused on discovering, developing and delivering novel medicines for rare diseases, today announced financial results for the full year ended December 31, 2020.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “During 2020, Amicus remained resilient on our journey to becoming a leading global rare disease biotechnology company. Despite the challenges of COVID, Amicus emerged from 2020 a better and stronger company organizationally, strategically, scientifically and financially. Galafold continues its path to becoming the worldwide standard of care for Fabry patients with amenable variants. And we are steadfast and passionate in our commitment to advancing AT-GAA to global regulatory submissions as fast as possible for the benefit of all people living with Pompe disease. The data from the Phase 3 PROPEL study we believe continue to show the overwhelmingly positive benefits of AT-GAA compared to the only approved medicine in this devastating disease. And the unmet need in Pompe is so great. We have the team, the resources and the programs that strongly position us to achieve our vision of delivering groundbreaking new medicines and hopefully, one day, cures for people living with rare diseases.”

Corporate Highlights

• Global revenue for Galafold^® (migalastat) in the full year of 2020 was $260.9 million. Full year revenue represented a year-over-year increase of 43% from total revenue of $182.2 million in the full year of 2019. On a constant currency basis, full year 2020 total revenue was $258.6 million, representing operational revenue growth measured at constant currency exchange rates of 42%, which was further benefited by a positive currency impact of $2.3 million, or 1%. Galafold performance was driven largely by strong patient demand. Global compliance and adherence rates continue to exceed 90%.
  
  
• Results from the global Phase 3 PROPEL clinical study of AT-GAA in late-onset Pompe disease (LOPD) were presented at the 17th Annual WORLDSymposium™ 2021. The Company plans to complete the BLA submission in the second quarter of this year and anticipates additional regulatory submissions in the European Union and in other geographies throughout 2021.
  
  
• The U.S. Food and Drug Administration (FDA) granted Fast Track Designation to the CLN6 Batten disease gene therapy, AT-GTX-501. The Fast Track program facilitates the development and accelerates the review of new drugs for serious conditions, which have the potential to address unmet medical needs. A drug development program with Fast Track designation is afforded greater access to the FDA for the purpose of expediting the drug's development, review and potential approval.
  
  
• Initial clinical data from the Phase 1/2 CLN3 gene therapy study were presented at the 17th Annual WORLDSymposium™ 2021. Results suggest early signs of disease stabilization and the potential to slow the neurological disease progression in children living with CLN3 Batten disease. Regulatory interactions are ongoing and the Company expects to submit the protocol for the next clinical study in the second half of this year.
  
  
• Preclinical data from the Company’s Fabry disease gene therapy clinical candidate, AT-GTX-701, presented at the 17th Annual WORLDSymposium™ 2021. As part of the research collaboration with the Gene Therapy Program of the Perelman School of Medicine at the University of Pennsylvania (Penn), initial data from the Fabry AAV gene therapy with an engineered GLA transgene improved for stability demonstrated greater substrate reduction than wild type constructs across all tissues and doses. These findings further validate the synergies of combining Amicus-engineered transgenes with Penn’s AAV technologies to develop next generation gene therapies.
  
  
• Cash position sufficient to achieve self-sustainability without the need for any future dilutive financings. The Company continues to carefully manage expenses and investments, while executing on the Galafold launch, proceeding with AT-GAA global regulatory submissions and advancing development programs. 

Full Year 2020 Financial Results

• Total revenue in the full year 2020 was $260.9 million, a year-over-year increase of 43% from total revenue of $182.2 million in the full year of 2019. On a constant currency basis, full year 2020 total revenue was $258.6 million, representing operational revenue growth measured at constant currency exchange rates of 42%. Reported revenue was aided by a positive currency impact of $2.3 million, or 1%.
• Cash, cash equivalents, and marketable securities totaled $483.3 million at December 31, 2020, compared to $452.7 million at December 31, 2019.
• Total GAAP operating expenses of $476.8 million for the full year 2020 increased as compared to $464.3 million for the full year 2019, reflecting continued investments in our pipeline offset by decreased travel and third-party costs.
• Total non-GAAP operating expenses of $415.7 million for the full year of 2020 increased as compared to $411.8 million in the full year of 2019, reflecting continued investments in our pipeline offset by decreased travel and third-party costs.¹
• Net loss was $276.9 million, or $1.07 per share, compared to a net loss of $356.4 million, or $1.48 per share, for the full year 2019.

_{¹ Full reconciliation of GAAP results to the Company’s non-GAAP adjusted measures for all reporting periods appear in the tables to this press release.}

2021 Financial Guidance

• For the full-year 2021, the Company anticipates total Galafold revenue of at least $300 million to $315 million. Double-digit revenue growth in 2021 is expected to be driven by continued operational growth and commercial execution across all major markets, including the U.S., EU, U.K. and Japan.  
• Non-GAAP operating expense guidance for the full-year 2021 is $410 million to $420 million, driven by continued investment in the global Galafold launch, AT-GAA clinical studies and pre-launch activities, and advancing our gene therapy pipeline.²
• Cash, cash equivalents, and marketable securities totaled $483.3 million at December 31, 2020. Based on current operating models, the Company believes that the current cash position, which includes the net proceeds from the 2020 Senior Secured Term Loan, and expected future revenues are sufficient to fund the Company’s operations and ongoing research programs through to self-sustainability.

_{² A reconciliation of the differences between the non-GAAP expectation and the corresponding GAAP measure is not available without unreasonable effort due to high variability, complexity and low visibility as to the items that would be excluded from the GAAP measure.}

About Galafold 
Galafold^® (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 galactosidase alpha gene (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 over 40 countries around the world, including the U.S., EU, U.K., Japan and others.

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.

Non-GAAP Financial Measures
In addition to financial information prepared in accordance with U.S. GAAP, this press release also contains adjusted financial measures that we believe provide investors and management with supplemental information relating to operating performance and trends that facilitate comparisons between periods and with respect to projected information. These adjusted financial measures are non-GAAP measures and should be considered in addition to, but not as a substitute for, the information prepared in accordance with U.S. GAAP. We typically exclude certain GAAP items that management does not believe affect our basic operations and that do not meet the GAAP definition of unusual or non-recurring items. Other companies may define these measures in different ways. Full reconciliations of GAAP results to the comparable non-GAAP measures for the reported periods appear in the financial tables section of this press release. When we provide our expectation for non-GAAP operating expenses on a forward-looking basis, a reconciliation of the differences between the non-GAAP expectation and the corresponding GAAP measure generally is not available without unreasonable effort due to potentially high variability, complexity and low visibility as to the items that would be excluded from the GAAP measure in the relevant future period, such as unusual gains or losses. The variability of the excluded items may have a significant, and potentially unpredictable, impact on our future GAAP results.

Forward-Looking Statements
This press release contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 relating to preclinical and clinical development of our product candidates, the timing and reporting of results from preclinical studies and clinical trials, the prospects and timing of the potential regulatory approval of our product candidates, commercialization plans, manufacturing and supply plans, financing plans, and the projected revenues and cash position for the Company. The inclusion of forward-looking statements should not be regarded as a representation by us that any of our plans will be achieved. Any or all of the forward-looking statements in this press release may turn out to be wrong and can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. For example, with respect to statements regarding the goals, progress, timing, and outcomes of discussions with regulatory authorities, and in particular the potential goals, progress, timing, and results of preclinical studies and clinical trials, and revenue goals, including as they are impacted by COVID-19 related disruption, are based on current information.  The potential impact on operations and/or revenue from the COVID-19 pandemic is inherently unknown and cannot be predicted with confidence and may cause actual results and performance to differ materially from the statements in this release, including without limitation, because of  the impact on general political and economic conditions, including as a result of efforts by governmental authorities to mitigate COVID-19, such as travel bans, shelter in place orders and third-party business closures and resource allocations, manufacturing and supply chain disruptions and limitations on patient access to commercial or clinical product or to treatment sites. In addition to the impact of the COVID-19 pandemic, actual results may differ materially from those set forth in this release due to the risks and uncertainties inherent in our business, including, without limitation: the potential that results of clinical or preclinical studies indicate that the product candidates are unsafe or ineffective; the potential that it may be difficult to enroll patients in our clinical trials; the potential that regulatory authorities, including the FDA, EMA, and PMDA, may not grant or may delay approval for our product candidates; the potential that we may not be successful in commercializing Galafold in Europe, UK, Japan, the US and other geographies or our other product candidates if and when approved; the potential that preclinical and clinical studies could be delayed because we identify serious side effects or other safety issues; the potential that we may not be able to manufacture or supply sufficient clinical or commercial products; and the potential that we will need additional funding to complete all of our studies, commercialization and manufacturing. Further, the results of earlier preclinical studies and/or clinical trials may not be predictive of future results. With respect to statements regarding corporate financial guidance and financial goals and the attainment of such goals and statements regarding projections of the Company's revenue and cash position, actual results may differ based on market factors and the Company's ability to execute its operational and budget plans. In addition, all forward-looking statements are subject to other risks detailed in our Annual Report on Form 10-K for the year ended December 31, 2020 to be filed today. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. All forward-looking statements are qualified in their entirety by this cautionary statement, and we undertake no obligation to revise or update this news release to reflect events or circumstances after the date hereof.
