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

PHILADELPHIA, May 09, 2022 (GLOBE NEWSWIRE) -- Amicus Therapeutics (NASDAQ:FOLD), a patient-dedicated global biotechnology company focused on developing and commercializing novel medicines for rare diseases, today announced financial results for the quarter ended March 31, 2022.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, "Against a tumultuous market, we at Amicus have a deeply sharpened focus. We continue to ensure that Galafold gets to as many amenable people living with Fabry disease around the world, as seen by the significant first quarter performance of this precision medicine. We are committed to the regulatory approvals of AT-GAA for people living with Pompe disease, first in the United States and then in Europe and beyond. We are well on track with these anticipated approvals and the associated launch preparations, furthering our belief in the potential for this treatment regimen to become the new global standard of care in Pompe disease. And finally, we are laser focused on the financial strength of the business. This is anchored by the continued growth of Galafold and the anticipated approval of AT-GAA, each with strong exclusivity well into the late 2030s. Together this uniquely positions Amicus to deliver substantial value for shareholders and patients ahead."

Corporate Highlights

Global revenue for Galafold^® (migalastat) in the first quarter of 2022 was $78.7 million. First-quarter revenue represented a year-over-year increase of 18.5% from total revenue of $66.4 million in the first quarter of 2021. First quarter operational revenue growth measured at constant exchange rates (CER)¹ was 23.5%.
Galafold U.S. intellectual property estate strengthened following the issuance of eight new patents this year, including a composition of matter patent. The Galafold U.S. intellectual property portfolio now includes 35 orange book listed patents, 19 of which provide protection through 2038.
Long-term Phase 1/2 data of AT-GAA presented at the 2022 MDA Clinical & Scientific Conference in March. Study participants treated with AT-GAA for up to 36 months demonstrated persistent and durable effects on six-minute walk test (6MWT) distance, stability or increase in forced vital capacity (FVC), and reductions in biomarkers of muscle damage and disease substrate.
AT-GAA regulatory reviews progressing: In the U.S., the Food and Drug Administration (FDA) has set a Prescription Drug User Fee Act (PDUFA) action date of May 29, 2022, for the New Drug Application (NDA) and July 29, 2022, for the Biologic License Application (BLA), reflective of the two components of AT-GAA. Following a positive late cycle review meeting, the Company continues to expect the FDA to approve the applications together by the July 29, 2022 action date. In the EU, the Committee for Medicinal Products for Human Use (CHMP) positive opinion is expected in late 2022.
AT-GAA launch preparations accelerating: Development of pre-launch activities, targeted investments in additional personnel, and launch inventory build are fully underway as the Company believes AT-GAA has the potential to become the new standard of care treatment regimen for people living with Pompe disease.
Multiple expanded access programs in place driving significant enthusiasm for AT-GAA. In the U.K., under the Early Access to Medicines Scheme (EAMS) multiple physicians have requested access across all the leading Pompe centers in the country.
Financial position sufficient to achieve profitability² in 2023. Through careful management of expenses, the Company is on the path to achieve profitability in 2023, as it executes on the global expansion of Galafold and prepares for the global launch of AT-GAA.
2022 Environmental, Social, and Governance (ESG) Report published. The Amicus ESG report highlights its dedication to patients alongside the Company's environmental, social, and governance responsibilities.

First Quarter 2022 Financial Results

Total revenue in the first quarter 2022 was $78.7 million, a year-over-year increase of 18.5% from total revenue of $66.4 million in the first quarter of 2021. On a constant currency basis, first quarter 2022 total revenue growth was 23.5%. Reported revenue was offset by a negative currency impact of $3.3 million, or 5.0%.
Cash, cash equivalents, and marketable securities totaled $411.2 million at March 31, 2022, compared to $482.5 million at December 31, 2021.
Total GAAP operating expenses of $147.1 million for the first quarter 2022 increased as compared to $112.9 million for the first quarter 2021.
Total non-GAAP operating expenses of $109.0 million for the first quarter of 2022 increased as compared to $90.5 million in the first quarter of 2021, reflecting manufacturing costs to support the AT-GAA launch and non-recurring expenses related to the reprioritization of the gene therapy portfolio.³
Net loss was $85.3 million, or $0.30 per share, compared to a net loss of $65.7 million, or $0.25 per share, for the first quarter 2021.

2022 Financial Guidance

For the full-year 2022, the Company anticipates total Galafold revenue of $350 million to $365 million at constant exchange rates¹. Double-digit revenue growth between 15 and 20% at CER¹ in 2022 is expected to be driven by continued underlying demand from both switch and naïve patients, geographic expansion, the continued diagnosis of new Fabry patients and commercial execution across all major markets, including the U.S., EU, U.K., and Japan. Applying average April 2022 exchange rates, the negative currency impact on full-year 2022 Galafold reported sales would be approximately 6%.
Non-GAAP operating expense guidance for the full-year 2022 is $470 million to $485 million, driven by continued investment in the global Galafold launch, AT-GAA clinical studies and pre-launch activities, in addition to certain non-recurring costs for manufacturing to support the global launch of AT-GAA and committed obligations for the gene therapy portfolio. In 2023, Amicus expects non-GAAP operating expense levels to come down to a similar level as in 2021.⁴
Cash, cash equivalents, and marketable securities totaled $411.2 million at March 31, 2022. Based on current operating models, the Company believes that the current and projected cash flows are sufficient to achieve self-sustainability.

¹ In order to illustrate underlying performance, Amicus discusses its results in terms of constant exchange rate (CER) growth. This represents growth calculated as if the exchange rates had remained unchanged from those used in the comparative period. Full year 2022 Galafold revenue guidance utilizes the average actual exchange rates for 2021

² Based on projections of Amicus non-GAAP Net Income under current operating plans, which includes successful AT-GAA regulatory approvals and continued Galafold growth. We define non-GAAP Net Income as GAAP Net Income excluding the impact of share-based compensation expense, changes in fair value of contingent consideration, loss on impairment of assets, depreciation and amortization, acquisition related income (expense), loss on extinguishment of debt, loss on impairment of assets, restructuring charges and income taxes

³ 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.

⁴ 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, 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, 2021 and Form 10-Q for the quarter ended March 31, 2022, to be filed today.
