Great. Thank you, Andrew, and welcome everyone to our first quarter 2022 results conference call. I'm pleased to highlight the successful start to the year across our business and reiterate the Amicus team's focus on our business priorities despite as we all know this tumultuous stock market environment across the biotech sector. Let me begin by emphasizing that we are sharply focused on three primary objectives; one, continue to advance Galafold to as many patients and as many geographies as possible. Two, secure approvals for and launch AT-GAA in Pompe Disease globally. Three, ensure the financial strength of Amicus, including the path to profitability without the need for any further equity-based financing. As we did in this morning's press release, let me elaborate on several key accomplishments. First, Galafold continues its strong performance and remains the cornerstone of our success. With $78.7 million in first quarter revenue and nearly 19% increase from a year ago, we continue to be very pleased with the uptake of Galafold globally. Its growth thus far this year is meeting or exceeding our objectives in all key geographies. We are excited to announce also that the intellectual property portfolio estate for Galafold has been strengthened by the issuance of eight new patents this year. Together there are now 35 orange book listed issued patents related to Galafold in the United States, which provide protection through 2038, including the very important and recently issued Composition of Matter patent. This portfolio will provide broad and long-term intellectual property rights well into the late 2030s for this novel precision medicine. We expect significant growth for Galafold in 2022 and with this strengthened IP protection, believe that it has a long runway into the next decade and beyond, and that Galafold continues to have the potential to achieve $1…

Great, thanks, John. Good morning, everyone. Let me start by walking you through in more detail our Galafold performance for the quarter on Slide 7. For the first quarter again, total product revenue grew 18.5% to $78.7 million globally. This was driven by strong new patient accruals and continued sustained patient compliance and adherence rates. The geographic breakdown of revenue during the quarter was consistent with what we've seen historically with $55 million or 69% of revenue generated outside the United States, and the remaining $24 million or 31% coming from within the United States and this is in line with the roughly 70/30 split that we expect as we continue to grow both parts of the business. Now turning to Slide 8, Q1 results highlight the strength of the global commercial efforts. This business continues to be incredibly resilient with patients added in all major markets and an operational growth rate of 23.5% over the same quarter last year at constant exchange rates. As you can see in the two graphs depicted on this slide, Q1 results follow the revenue pattern we've continued to observe were due to a variety of factors including timing of orders, as well as pay reauthorizations in the United States. The rate of growth is typically nonlinear, and a smaller percentage of annual revenue falls into Q1. Here we've also called out several of the drivers and metrics which will lay the foundation for growth this year and beyond. We ended the first quarter with a little under half of the global market share of treated amenable patients. And while the global mix remains about 55% switch patients and 45% naïve patients. In many geographies, we're starting to see stronger uptake in naïve populations, which is in line with our strategy from launch. So…

Thanks, Bradley and good morning, everyone. Starting here on Slide 11, we highlight the ongoing work we're doing to build the body of evidence around Galafold. First, we continue to look to broaden the global labels within the adolescent and pediatric populations as well as adding additional variants or mutations to the label. Second, our medical team continues to work diligently on our publications and medical conference schedule. Long-term data was published last year in the molecular genetics and metabolism reports, as well as presented at the 2022 World Symposium in February. These long-term data highlighted stable renal function during treatment up to eight and a half years on Galafold irrespective of treatment status, gender or phenotype and inclusive of classic males. We have also presented at conferences, and recently submitted a publication looking at Fabry outcomes measured by rates of kidney, cardiac and CNS events, which we believe compare favorably to similar studies in the medical literature. Third, Amicus admitted over 500 patients in a large global registry as part of our post marketing commitments, and is exploring ways to leverage this wealth of long-term data to add to the growing body of evidence for Galafold through publications, as well as towards providing confirmatory evidence to support our remaining post marketing requirements. Additionally, we have multiple other ongoing and planned Phase 4 studies and we continue to move forward. And last as Bradley mentioned, we continue to add to our IP coverage and now have 35 orange book listed patents. We see all of this continued work on evidence generation for Galafold as an important driver of the long-term success. Moving on to Slide 13 and our AT-GAA program. It's important to recognize that Pompe disease continues to pose a range of health challenges for people affected by the…

Sorry about that. Thanks, Jeff. Just on Slide 18 as Jeff mentioned, as we talk through our launch preparations for AT-GAA we are poised for another successful product launch building on success of our Galafold franchise, although unlike when we launched Galafold when we were hiring the commercial organization and supportive infrastructure from scratch, we now have a presence in over 40 countries around the world, including all the major markets, and that team will be largely the same that will launch AT-GAA with only a small handful of new FTEs [ph] needed. We have experience across all areas that are needed for successful drug launch, regulatory, commercial, supply chain, experience with payers, reimbursement and access. In addition, and most importantly, the key relationships with the physicians and medical community around the world. We're very confident in our world class commercial organizations that we can leverage with their experience and relationships and deliver AT-GAA to people living with Pompe disease around the world. From the team, the medical education, the now published Phase 3 data in the highly regarded Lancet Neurology, our experience and focus on reimbursement and access, and again, all the strategic planning that we're doing together with building inventory with our partners in WuXi Biologics, we believe we're in very strong position for a second rapid and successful launch for Amicus. And with that, let me turn the call now over to Daphne Quimi, our Chief Financial Officer to review our financial results, guidance and outlook. Daphne?

Thank you, Bradley and good morning, everyone. Our financial overview begins on Slide 20 with an overview of our Q1 revenue performance and FX impact. For the first quarter we achieved Galafold revenue of $78.7 million, which is a 19% increase over the same period in 2021. This includes a year-over-year operational growth of 24% and a negative currency impact of 5%. As Bradley highlighted, given 69% of Galafold revenue is generated outside the U.S. we see significant FX exposure to our reported revenue numbers. Applying average April 2022 exchange rates, the FX impact on 2022 full year Galafold reported sales would be a negative impact of approximately 6% to our reported numbers for the whole year. Slide 21 outlines our income statement for the first quarter ending March 31, 20 22. Cost of goods sold as a percentage of net sales was 10.4% in the year as compared to 10.2% for the prior year period. Total GAAP operating expenses were $146.5 million in the first quarter as compared to $112.9 million in the first quarter of 2021. The increase reflected expenses related to the reprioritization of the gene therapy portfolio, manufacturing and marketing costs to support the global launch of AT-GAA and increased stock compensation expense. On a non-GAAP basis, total operating expenses were $109 million in the first quarter, as compared to $90.5 million in the first quarter of 2021. We define non-GAAP operating expense as research and development and SG&A expenses excluding share based compensation expense, loss on impairment of assets, changes in fair value of contingent consideration and depreciation. Net loss for the first quarter of 2022 was $85.3 million or $0.30 per share, as compared to a net loss of $65.7 million or $0.25 per share for the prior year period. As of March 31,…

Great, thank you, Daphne, and Jeff and Bradley as well. So as you can see, we have been relentlessly focused on performance across the business driven by our team of global entrepreneurs, passionate people who have led and will continue to lead us on our patient focused mission. And with that, operator, we're happy to take questions.

Thank you. [Operator Instructions] Thank you. Your first question comes from Ritu Baral from Cowen. Your line is now open.

Good morning, everyone. Thanks for taking the question. John, since you mentioned that labeling discussions for AT-GAA have already started, can you talk to the tenor, the tenor of those discussions around the breadth of the label? And then, as you're having those discussions overall, including on manufacturing, I guess, what's negotiable on that WuXi inspection? Has there been prior inspections? So there's only elements, I guess, to focus on? Can you give us a little more clarity around that? Thanks.

Sure Ritu, good morning, thank you. So I'll take both parts of those. With respect to the labeling negotiations, obviously we take it as a very good sign that we're moving through negotiations on the label, and discussions with the FDA. I'm not going to talk about exactly what we're discussing with the FDA. Obviously, the things that we care about, so for instance, making sure that we highlight the important data and the switch population and other matters, we feel really good about the tone and tenor of those negotiations. And we continue to believe that the label will support a launch that will provide access to people living with Pompe disease that would be in patient's interests, and also commercially very viable. But again, we think it's very good and continued with the practice that we've had with the FDA of spirited discussions. And again, we're very confident in the provability of AT-GAA with a label that will support extraordinary success for patients and for the product commercially. You know, with respect to manufacturing, the FDA has indicated all along that they're going to have to do an onsite inspection of the WuXi Biologics facility in WuXi City in China. We've completed with WuXi all of the preparatory work necessary to facilitate that inspection. We've completed for instance, in March a mock inspection with our auditors internally, that went very well. We continue to look at all options with the FDA around other ways in which they may conduct the inspection. And right now we continue to expect that the PDUFA action date of July 29, would be something that would be able to be achieved in this timeframe.

Great, thanks.

Sure Ritu, thank you.

Your next question comes from Anupam Rama of JPMorgan. You may now state your question.

Hey, guys, thanks so much for taking my question. May be following up on Ritu's question here about the FDA review of the WuXi facility in China, could you expand a little bit on the strategies that you're kind of exploring? You've previously talked about maybe FDA employees in the region helping conduct the review, what other strategies are being employed here? Thanks so much.

Sure, thanks. I won't comment on any ongoing discussions with the FDA. You're correct on upon that the FDA does have FDA designated employees in China. The WuXi City facility is not currently under lockdown a lot of the complexity here has to do with Shanghai itself. Again, to remind everybody, WuXi is about three or four hours north of Shanghai. So we continue to expect that we will need a full onsite inspection by the FDA. That's what they've indicated to us and we expect that that could be completed by the July 29, PDUFA action date. In parallel, we are also evaluating all other options, remote interactive options and other ways in which the inspection could be conducted ways in which they've done it with other sponsors, as well. So we're fully prepared for all potential contingencies.

Thanks so much for taking the question.

No, of course Anupam, thank you.

Our next question comes from Ellie Merle from UBS. Your line is open.

Hey, guys, thanks for taking the question. Maybe just on sort of Pompe launch preparations, maybe first, if you could give the latest color in terms of how the EAP is going in the UK, and maybe any color in terms of uptake and physician feedback there. And then just thinking towards the U.S., maybe just if you could give color on your expectations for uptake in patients that have already maybe started on Neo GAA and how you're thinking about sort of uptake in the ERT switch patients as well as potentially switches from Neo GAA and any initial thoughts there? Thanks.

Sure. Thank you Ellie, good morning. Bradley, do you want to handle both of those on the EAP as well as our launch expectations in the United States?

Sure. Thanks, John. Thanks Ellie for the questions. So first for expanded access, yes we've continued to provide extended access through a number of mechanisms, probably the most visible one or the most important one is EAMS at this point, which is their Early Access Medicine Medicine Scheme in the UK. And that's important because both AT-GAA and Neo GAA are available through that scheme. And what we've heard is very positive feedback towards AT-GAA. We know that all of the key centers that prescribe Pompe medication have asked for and are now receiving the EAMS, sorry access to AT-GAA through the EAMS program. So that's, I think, really important to see how much support and excitement there is for AT-GAA through that program. We would expect that number to continue to climb and it's the UK is actually a pretty significant Pompe market. And so, we think that's a great opportunity for patients to get access to AT-GAA while the UK is reviewing the application, and obviously gives us a great view into how the community sees AT-GAA as a potential treatment for Pompe. And again, we have other mechanisms in other countries around the world as well, where we see strong uptake. In the United States, to your point around opportunities for uptake for sure we think the switch population, as we've noted all along, is the clearest unmet medical need. We are, as John alluded to continuing to negotiate what the indication would be for AT-GAA. But if we just focus on the two segments, you talked about experienced patients with -- who are on Myozyme and experienced patients who perhaps have gone to Neo GAA, I think from our perspective, I think, any Pompe patient who falls within the label would be indicated for AT-GAA. We believe that the data show that our product has significant improvements, in particular in switch patients, and would encourage folks to re-familiarize themselves with the longer-term data from the studies on the Neo GAA and the Phase 1/2, and then the publicly available data and the Phase 3 to see how those patients perform over time. But we're very confident that AT-GAA could have utility in both of those populations. And we think the data are from there and you'll see over time that we have the chance to be we think standard of care for all Pompe patients.

Great, thanks.

Your next question comes from Joe Schwartz from SVB Securities. Your line is now open.

Hi, everyone. This is Beth Feindt-Scott on for Joe. I was just wondering if you could share any physician feedback you received on the 36 months data you presented at the MDA Conference this year? And also building off that, I believe you said you plan to have open label extension data from the PROPEL trial later this year. We were just wondering if you'll be able to share that open label extension data from PROPEL with regulators ahead of the approval decision? Thanks.

Great, thanks Beth and good morning. Jeff, do you want to take both of those on the physician feedback and the 36-month data that we shared at World as well as any color on the open label PROPEL Study extension data?

Sure, yes. You know, one of the biggest unmet needs in Pompe is really durability of treatment effects. I think that's something we see now in every study, that's a lot longer-term, just for whatever reason, these patients show some potential initial mixed benefit, but then they did generally tend to decrease longer-term. And I think we've seen that now with multiple treatments that the long-term data seems to show some weaning off effect. And I think what was really exciting about that Phase 1/2 data that we just presented was after three years, those improvements, we saw in this Phase 1/2 patients have been maintained. And again, that was in switch patients, naive patients. So we were excited by that data. We got very good reception to that data as well. And then yes, this year, we will continue to -- we have patients we've been following now in that Phase 1/2 that are now five plus years of treatment. So we'll have later data cuts even of that Phase 1/2 population and in addition, we'll have data cuts from our ongoing PROPEL extension. The patients after one year are continuing on AT-GAA or that Lumizyme arm, that switch to AT-GAA, you know, we'll have at least one year of data on those patients. We don't have specific dates and conferences we can announce yet, but we do plan to have that data disclosed here this year. But we don't have necessarily obligations to include that data in the submissions in the U.S. or the EU. You know, at some point we may add that longer-term data, but for the initial review and approval, we don't need to add additional data.

Great, thanks, Jeff. Thank you, Beth.

Your next question comes from Kristen Kluska from Cantor Fitzgerald. Your line is now open.

Hi, good morning, everybody. Thanks for taking my question. I wanted to ask outside of all the additional findings that you've presented and published on AT-GAA since the PROPEL readout, what else gives you confidence heading into this decision, but then also in the role that AT-GAA could place in the market? So for example, both around the agency commentary on the unmet need to the EAMS next [indiscernible] labels and then also publications around the different endpoints, so for example, I know in the past, you really emphasized some of the newer work on SEC and the understanding around mortality risk?

Great, thank you, Kristen, good morning and actually made our job easier by highlighting a number of the different elements that we think will go into making this a differentiated medicine for people. Again, I'll just highlight that this was the PROPEL Study was the largest study ever conducted in any Lysosomal Storage Disease. And nearly 80% of the patients in that study had switched from the standard of care from myozyme-lumizyme, they had switched to AT-GAA. And again, the vast majority of people who we see taking AT-GAA for the first number of years, are going to be people who are currently on enzyme replacement therapy. Whether that be myozyme or lumizyme or any of those who may already be switching to the Neo product, we would expect and hope for a label to support that. So again, the data that we have in that very large study, particularly in that switch patient population, again showing the nominal statistical significance on six-minute walk, on forced vital capacity, and virtually all secondary endpoint. This is a very sophisticated patient community and physician scientist community and they will be data driven. So the look at the data from that study and again to look at the data that Jeff just talked to the long-term durability data that we see from our Phase 1/2 and in the months ahead the data that will show we hope, with the long-term durability patients in the PROPEL Study. So we think all of the data from all the clinical studies together with a real world experience of physicians, now with multiple uses in patients ranging from infants all the way through adults in the EAMS study, we would expect, again to Bradley's point significant numbers of patients in the United Kingdom to switch from existing standard of care enzyme, from the approved myozyme to AT-GAA over the coming months and into 2023 as we then look to the full approval. So I think all of that builds the totality that's overwhelmingly, we think positive for AT-GAA and presents a very, very strong risk benefit profile for physicians. We know doctors and as we're engaged appropriately with physicians, patient community are extremely excited for the potential option of AT-GAA. So Jeff, I don't know if you've got any other comments to add.

No, I think John you covered it well, it's really just that consistency, the fact that cross parameters that we measured in patients that we treated, all the different endpoints across the key manifestations, either nominally, significantly or numerically favored AT-GAA over alglucosidase alfa and then across naïve patients, experienced patients, non-ambulatory patients from Phase 1/2, patients with higher or lower baseline severities, we've just seen a really consistent effect. And I think that that's really the key that consistency adds into the weight and the meaningfulness of the treatment.

Now, it's an important point, Jeff to add and again Kristen and I'll probably summarize it that when you look across all the data that we've had in now more than six years of clinical research, to look at the magnitude, the consistency and the durability of that data, we think are particularly impressive, and will bode very well. And again, this is a market where you've had enzyme replacement sales last year, global revenue with one product of over $1 billion. And with increased diagnosis rates and the ability to affect and positively affect we hope, the lives of many people living with Pompe and finding many more new patients broadly for us and for others in the market. We think this is a market with the potential for more than $2 billion in global revenue. And we think we have the potential for at least half of that by the end of this decade. So when you step back then and look at Amicus with Galafold is the cornerstone of our success, where we are today and where we'll take it with the length of that intellectual property protection well into the 2030s, with $1 billion revenue potential for Galafold, with what we believe will be an approved product in Pompe disease that we think has the potential to become the standard of care, or at least split the market with the existing entrenched other competitor in the field, that's another potential billion dollar revenue product, also with significant intellectual property protection, including Composition of Matter on AT-GAA, extending well into the 2030s. That combined with the financial strength of a company, we think is pretty distinguished, particularly in this volatile market. So thank you.

Thank you, John.

Thank you, Kristen.

Our next question comes from Dae Gon Ha of Stifel. You may now state your question.

Hey, good morning, guys. Thanks for taking our question. On the labeling discussion, I was kind of curious, in terms of differentiating AT-GAA, from Neo GAA, wondering if you can comment on whether FDA has asked for any additional data cuts we've seen some of that happen recently then perhaps that could accentuate some of the profiles that you were just alluding to? Thank you very much.

Yes, thanks Dae Gon, they've not asked for any additional data cuts. We have supplied them with all the data. So for instance, they've seen the 36-month data from the Phase 1/2 study, but they've not asked for instance, for the PROPEL Study for any additional data cuts.

Thank you.

Thank you.

Your next question comes from Salveen Richter of Goldman Sachs. Your line is now open.

Hey, guys, thanks for taking the question. This is Elizabeth on for Salveen. Maybe going back to some of the initial questions, how do you expect to message around the WuXi inspection and should we expect you guys to communicate when that takes place to the Street? And then maybe you could just remind us of what we should expect to learn from the first FDA review date? Thank you.

Sure, let me take that first part, again to be perfectly clear, and we've had this discussion with the agency, we expect no action on May 29, from the agency. And we expect both the NDA and the BLA, we expect action by July 29, which of course we hope to be approval. With respect to look, there's a lot of activities going on right now with labeling discussion, all of our internal launch preparations. But in addition, of course, the important final CMC parts, important to note that this has -- we've had tremendous manufacturing history here with WuXi and we think that bodes quite well. And we've been very successful in all of our discussions and much of the focus at the BLA review has been on the CMC section which we fully expected, dozens and dozens of information requests from the agency going all the way back to September into the early part of this year. We believe we've satisfied the FDA's questions with respect to the CMC section and we do have this important WuXi inspection. Again, a lot of different ways we think that could be satisfied. We're at the point now we're not going to be providing the Street with, I mean, literally daily or week to week. We're having our exchanges with the agency. We're not going to provide the blow by blow, including updates on manufacturing inspections. You know, when did it take place? When is it scheduled? How did it go? What did they ask? We're not going to provide that color. We're now into the final stretches, coming up to the July 29, PDUFA date. So continue to expect the medicine to be approved by the PDUFA date. And obviously, if there are any changes to that we would provide that update to the Street. But again, we remain very, very confident in the approvability of AT-GAA and are fully prepared for the launch in the United States. And again, we're in active discussions with the EMA and MAA and expect the CHMP opinion before the end of the year with launch in Europe in 2023.

Great, thanks for the color.

Great, thank you, Elizabeth. Your next question comes from Yun Zhong of BTIG. Your line is now open.

Hi, good morning. Thanks very much for taking the questions. Can you remind us the size of the sales force that you have in the U.S. and in Europe? Did you or do you plan to increase the size in preparation for the AT-GAA launch? And also given that it's still an IV infusion not like the oral for Galafold, do you expect that you will still have to face some type of COVID related challenges when you launch AT-GAA?

Yes, sure. Bradley, I'll go ahead and take that over to you particularly to highlight the operating leverage that we have at Amicus.

Yes, thanks, John. So just as a reminder, what we've characterized is we have about 150, global field personnel between sales, medical, market access, et cetera. That organization is effectively the organization we will use to launch AT-GAA. So we get significant leverage out of the Galafold commercial organization, commercial and medical organization, I should say. What we've said is, we would intend to add perhaps less than a dozen FTEs globally to support the launch, primarily in direct marketing, direct medical and then in the United States, some market access folks in particular in support of our Patient Assistance hub. So highly leverageable organization to be able to support the launch of a AT-GAA. In terms of your second question, as relates to COVID impacting the uptake of AT-GAA, at this point, based on what we know from Galafold, based on where we see the global markets evolving, we don't expect any significant impact on AT-GAA uptake. Of course, we'll continue to monitor that. But I think the trends we're seeing now give us good confidence that we're moving into a place where patient care is largely able to move forward perhaps in a slightly evolved way, perhaps more hybrid interactions between our field force and physicians. But at this point, we don't see significant impact by COVID on our AT-GAA launch.

Great, thank you.

At this time, I would now like to turn the conference back to Mr. John Crowley, Chairman and CEO for closing remarks.

Great, thank you, operator. Thank you, everybody, for listening, for the great questions. As you can see, we're sharply focused on all of these strategic priorities for Galafold, AT-GAA, our pipeline and the financial strength for the company. So we will continue to press on onward. Thank you, have a great day.

This concludes today's conference call. Thank you and have a great day.
