Conference Call and Webcast Today at 8:30 a.m. ET

CRANBURY, N.J. , Aug. 10, 2020 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq: FOLD), a global, patient-dedicated biotechnology company focused on discovering, developing and delivering novel medicines for rare diseases, today announced financial results for the second quarter ended June 30, 2020. The Company also summarized recent program updates and reiterated its full-year 2020 guidance.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “During the second quarter, we made tremendous progress advancing our mission for patients and are on track to achieve our 2020 key strategic priorities, including our global Fabry launch, Pompe late-stage development program, and advancing our industry-leading gene therapy pipeline. Following our strategic financing in July, Amicus is firmly on a path to profitability without the need to access the equity markets. Through these efforts, we remain strongly positioned 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 second quarter of 2020 was $62.4M. Second quarter revenue represented a year-over-year increase of 41% from total revenue of $44.1 million in the second quarter of 2019. On a constant currency basis, second quarter 2020 total revenue was $63.3 million, representing operational revenue growth measured at constant currency exchange rates of 43%, which was offset by a negative currency impact of $1.0 million, or 2%.
• Strong second quarter revenue represents the continued performance across the global business, including new patient starts from switch and naïve patients throughout the quarter in all major regions, including that hardest hit by COVID-19. Performance driven largely by strong patient demand. Global compliance and adherence rates continue to exceed 90%.
• 1,000+ mutations added to the EU Galafold label.  This update includes a number of new mutations identified by creating and testing all possible single-base pair point mutations in the GLA gene. Including this list will help physicians assess treatment options in an expeditious manner.  Amenable mutations continue to represent up to half of all people living with Fabry disease.
• Global Phase 3 PROPEL clinical study of AT-GAA in late-onset Pompe disease (LOPD) remains on track for top line data in 1H21. To date, 97%+ of the 2,810 planned infusions and assessments for the ongoing PROPEL study have been completed on schedule. The Company plans to initiate a rolling BLA for AT-GAA in the second half of 2020, completing final submission in the first half of 2021.
• Expanded Access Program for infantile-onset Pompe patients underway. Amicus has initiated an expanded access program for its investigational medicine AT-GAA for young children living with infantile-onset Pompe disease (IOPD).
• Additional Phase 1/2 CLN6 data to be presented this year at the Child Neurology Society Annual Meeting in October. Regulatory interactions are ongoing and the Company expects to provide feedback on the path forward in early 2021.
• Initial data from the Phase 1/2 CLN3 study expected in early 2021 based on changes in medical conference schedules. Regulatory interactions are ongoing and concurrent with the data, the Company expects to provide feedback on the regulatory pathway.
• Positive preclinical Pompe gene therapy data presented at American Society of Cell and Gene Therapy meeting in May. Positive results showed the Amicus engineered hGAA having better targeting and clearance of glycogen storage in Pompe mice. Preliminary data in non-human primates suggested therapeutically relevant expression levels in target organs.
• Cash position sufficient to achieve self-sustainability without the need for any future dilutive financings. The previously announced debt facility places Amicus firmly on a path to profitability, while the Company continues to carefully manage expenses and investments, while executing on the Galafold launch and advancing development programs. 

2020 Key Strategic Priorities

• Achieve $250 million to $260 million of global product revenue for Galafold
• Complete Pompe Phase 3 PROPEL study, enroll pediatric studies and advance manufacturing to support 2021 BLA and MAA
• Advance clinical development, manufacturing and regulatory discussions for CLN6 and CLN3 Batten programs
• Progress Pompe gene therapy towards Investigational New Drug (IND) application and disclose up to two additional IND candidates
• Maintain strong financial position

Second Quarter 2020 Financial Results

• Total revenue in the second quarter 2020 was $62.4 million, a year-over-year increase of 41% from total revenue of $44.1 million in the second quarter of 2019. On a constant currency basis, second quarter 2020 total revenue was $63.3 million, representing operational revenue growth measured at constant currency exchange rates of 43%, which was offset by a negative currency impact of $1.0 million, or 2%.
• Cash, cash equivalents, and marketable securities totaled $309.6 million at June 30, 2020, compared to $452.7 million at December 31, 2019.
• Total GAAP operating expenses of $107.0 million for the second quarter 2020 decreased as compared to $115.2 million for the second quarter 2019, reflecting decreased travel and third-party costs, offset by continued investments in our gene therapy pipeline.
• Total non-GAAP operating expenses of $95.9 million for the second quarter of 2020 decreased as compared to $103.6 million in the second quarter of 2019, reflecting decreased travel and third-party costs, offset by continued investments in our gene therapy pipeline.¹
• Net loss was $52.5 million, or $0.20 per share, compared to a net loss of $84.6 million, or $0.36 per share, for the second quarter 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.

2020 Financial Guidance

• For the full-year 2020, the Company anticipates total Galafold revenue of $250 million to $260 million based on the average exchange rates for 2019.
• Non-GAAP operating expense guidance for the full-year 2020 is $410 million to $420 million, driven by continued investment in the global Galafold launch, AT-GAA clinical studies, and advancing our gene therapy pipeline.²
• Cash, cash equivalents, and marketable securities totaled $309.6 million at June 30, 2020. Based on current operating models, the Company believes that the current cash position, along with the net proceeds from the 2020 Senior Secured Term Loan and expected revenues, is sufficient to fund the Company’s operations and ongoing research programs through to profitability.

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 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, including as they are impacted by COVID-19 related disruption, are based on current information.  The potential impact on operations 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. 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, 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 and manufacturing. Further, the results of earlier preclinical studies and/or clinical trials may not be predictive of future results. Statements regarding corporate financial guidance and financial goals and the attainment of such goals. With respect to 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, 2019, the Quarterly Report filed on Form 10-Q for the quarter ended March 31, 2020, and the Quarterly Report filed on Form 10-Q to be filed today.
