I will turn the call over to Justin. Thank you, Lindsey, and good afternoon. As everyone on this call knows, there is an enormous unmet need in ALS and other relentlessly progressive and fatal neurodegenerative diseases. It is our mission at Amylyx to one day end the suffering caused by these diseases. Our treatment, RELYVRIO, enables us to make meaningful advances toward and continued investment in our mission. During the first quarter, we generated $71.4 million in net product revenues, reflecting the significant progress we continue to make toward our goal of ensuring every eligible person living with ALS has access to RELYVRIO. RELYVRIO is the first and only approved treatment for ALS that in a randomized placebo-controlled trial, both met its pre-specified primary outcome, demonstrating a statistically significant benefit in function, and showed a benefit on survival in a longer-term post-hoc analysis. These data suggest that ALS can in fact be treated. The full approval of RELYVRIO is an important step toward ALS one day being a manageable disease. The ALS community has been waiting for meaningful treatment options since the disease was first characterized over 150 years ago, and we believe that RELYVRIO will eventually be a foundational therapy for ALS. In the first quarter, we saw a continued high level of interest from the ALS community in RELYVRIO, broadened insurance coverage, and high levels of engagement with our Amylyx Care Team, also known as ACT. Just two quarters into launch, over 10% of the approximately 29,000 people living with ALS in the U.S. are now on RELYVRIO. Even with that success in our first six months, we have more to do. There remain many more thousands of people living with ALS in the U.S. and at least 200,000 people living with ALS globally. We are still in the early stages of our journey, and our team remains hard at work. Shifting to our plans internationally, we are diligently preparing to help bring our medicine to all eligible people living with ALS around the world. The regulatory review process in Europe remains ongoing, and we continue to expect an opinion from CHMP mid-year and a decision at the earliest in Q3. Overall, we believe we have a strong scientific position that is supported broadly by the ALS medical and advocacy community and a capable team who is leading our process. We continue to prepare to execute a successful launch in the E.U. if approved. We are proud of our team's progress on advancing our mission. Now I'll turn the call over to Margaret to share a commercial update. Thank you, Justin. As we enter the seventh month since our U.S. launch, we remain focused on three key priorities. The first is our effort to drive awareness and education about RELYVRIO among people living with ALS and clinicians. This includes educating that RELYVRIO is the first approved drug for adults with ALS to demonstrate a statistically significant benefit in function in a clinical trial, as well as a benefit on survival in a longer-term post-hoc analysis. Our efforts to drive awareness are yielding strong results. We are seeing continued interest and demand for RELYVRIO. As of March 31st, there were roughly 3,000 people on RELYVRIO in the U.S., more than double the number of people on RELYVRIO at the start of the quarter. We are pleased that this many people have gained access to our important treatment. I think it's worth spending a minute to provide some additional context on the strength of our launch. While we knew there was pent-up demand, the fourth quarter and first quarter were still well ahead of our expectations. The rate of net patients adds has begun to moderate as expected. However, we still see significant demand from people living with ALS and physicians alike. Importantly, we still have plenty of room for growth, both at the top ALS centers and the broader neurology community. Let me run through a few metrics that show our progress, but also the growth opportunities ahead of us. By the end of the first quarter, approximately 65% of the top 500 U.S. prescribers and approximately 95% of the key ALS centers had prescribed RELYVRIO to at least one person since launch. Prescribing remains fairly concentrated, with roughly 80 prescribers, mostly at major ALS centers, representing approximately half of all RELYVRIO prescriptions during the quarter. While we are encouraged with these data points, we see an opportunity for broader and deeper uptake at key ALS centers and the opportunity to continue to penetrate the group of top prescribers. We believe we have a large untapped opportunity for additional growth outside of this group of top prescribers as we expand our outreach and education efforts more broadly. Our second priority is engaging with payers to work towards our goal of ensuring that every eligible person who can benefit from RELYVRIO has access as quickly and efficiently as possible. At the end of the first quarter, U.S. insurers representing approximately 50% of covered lives have published formal coverage policies, including many of the key national and regional plans. The vast majority of these insurers provide broad access to RELYVRIO. For people living with ALS who go through the medical exception process, we are pleased that approximately 80% of prior authorization requests have been approved on the first admission. We continue to see a wide range of people living with ALS in terms of time since initial diagnosis, interested in and gaining access to RELYVRIO. Our team remains engaged with insurers across the country, and we continue to anticipate most plans will formalize their policies during the first half of this year. Our third priority is ensuring eligible people living with ALS have positive interactions through their treatment journey with RELYVRIO, and ALS clinics have positive interactions with Amylyx. This includes facilitating an organized, clear process to get people prescribed RELYVRIO access to the therapy as quickly as possible and optimizing people's experience accessing RELYVRIO as best we can. Our team is working expeditiously to get people living with ALS who have been prescribed RELYVRIO on therapy. In the first quarter, on average, it took about 30 days between receiving an enrollment form and RELYVRIO being shipped, down from a little more than 45 days in the fourth quarter. We expect to make additional progress on this metric in the second quarter with the benefit of more insurers having formal coverage decisions. In the limited cases where access hasn't been granted through an insurer, our interim access program and our patient assistance program are available for eligible patients. In the first quarter, roughly 10% of people taking RELYVRIO were part of these programs. We are pleased with the progress we've made so far on our goal to ensure that every eligible person living with ALS has access to RELYVRIO, which we see as a potential foundational therapy in neurodegenerative disease. Our launch is off to a strong start, and it is our hope that eventually RELYVRIO will become the most commonly used ALS medication. We are clearly focused on the launch of RELYVRIO in the U.S., we also have a large opportunity internationally. ALS is a global disease affecting more than 200,000 people worldwide. Interest in ALBRIOZA remains high in Canada, and we continue to negotiate public insurance coverage consistent with the expected public timelines for coverage. In addition, a few weeks ago, we appointed Masako Nakamura to lead our efforts in Asia-Pacific and Latin America as we pursue additional opportunities to bring AMX0035 to as many people with ALS globally as possible. She brings 30 years of commercial, general management, and operational leadership experience in the biopharmaceutical industry with a strong track record of introducing rare disease therapies worldwide across multiple therapeutic areas. We are very pleased that she decided to join our team to further explore opportunities for AMX0035 access around the world. I will now turn the call over to Josh to provide an important update on our R&D pipeline. Thanks, Margaret. We are very pleased with how quickly we are bringing our important new treatment to people with ALS. Our top focus day-to-day remains the success of our commercial launches. These efforts enable the continued investment needed to bring RELYVRIO to more people living with ALS worldwide. They also enable the research and development needed to advance our pipeline in support of our mission. There's tremendous scientific interest among the neurodegenerative community to further investigate AMX0035 in other diseases. We have positive randomized clinical trial data in ALS, encouraging biomarker data from the randomized phase II PEGASUS study in Alzheimer's disease, and a wealth of preclinical models demonstrating the effects of AMX0035 in reducing neuronal death. To prioritize which diseases to focus on, we look at the following criteria: Clear unmet need, strong scientific rationale, existing and robust understanding of the natural history of disease, biomarkers to track treatment effects, adjacencies and synergies with ALS, potential to move directly into a phase III pivotal study, and interest and support from KOLs. We are excited to announce today our plans to initiate a global pivotal phase III study of AMX0035 in Progressive Supranuclear Palsy, or PSP, a disease which meets all of these criteria. For those of you who may not be familiar with PSP, it is a rare, progressive, and fatal neurodegenerative disorder that affects body movements, walking and balance, speech and swallowing, and eye movement. It is typically fatal within just five to eight years. The estimated prevalence is five to seven in 100,000 people worldwide, translating to between roughly 15,000 to 20,000 people in the United States. There are currently no disease modifying treatments for PSP. In addition to PSP meeting our criteria for a significant unmet need with a well-characterized natural history, there is also a strong scientific rationale for the potential use of AMX0035 in treating PSP. PSP is both a disease of rapid and significant neurodegeneration, and its pathology is characterized by significant tau protein deposition in affected regions of the brain. In the PEGASUS Alzheimer's study of AMX0035 treatment demonstrated a statistically significant lowering of both phospho-tau 181 and total tau in the CSF of people living with Alzheimer's disease. AMX0035 is an oral, well-tolerated, FDA-approved medication for ALS that has been shown pre-clinically to protect neurons against degeneration and clinically to lower tau, the hallmark protein of PSP. This has led to significant and strong support from key opinion leaders in PSP, and we are excited to work with them to test AMX0035 in a phase III study, which I will now outline. In designing and planning the study, we have collaborated with key global academic leaders, people living with PSP, and advocacy groups working in this field. With an open IND in hand, we plan to enroll approximately 600 people in a randomized placebo-controlled study, making this likely the largest PSP trial to date. We expect to have the study up and running by the end of this year. We are hopeful that we can provide a new treatment option, especially since there are currently no disease modifying treatments available for this devastating disease. While we prepare to launch our pivotal phase III study, we also remain hard at work in Wolfram syndrome. Earlier this year, we announced HELIOS, a phase II trial studying AMX0035 in Wolfram syndrome. This study is now enrolling participants. Wolfram syndrome is a disease that leads to multi-system failure, resulting in blindness, deafness, diabetes, ataxia, neurodegeneration, and often death in early adulthood. Several papers characterize the disease as a prototypical disease of endoplasmic reticulum stress. As we have discussed in the past, we believe AMX0035 plays a role in reducing ER stress. Data on AMX0035 in models of Wolfram syndrome were published in Journal Clinical Investigation Insight. We believe this study will provide key data to guide future studies and expect top line results from the study next year. Importantly, we are also investing in new ALS research to continue to transform how the disease is treated. We believe that it is going to take a combination approach, targeting multiple cellular pathways implicated in disease pathogenesis to make ALS more and more manageable, and ultimately to find a cure. For this reason, we are investigating other therapies with different or potentially complementary pathways to treat ALS and other neurodegenerative diseases. This includes an antisense oligonucleotide called AMX0114 that our internal R&D team has developed. IND enabling studies of AMX0 114 are underway and progressing well. We continue to expect to build our pipeline both through internal and external sources. Before turning the call over to Jim, I wanted to share that PHOENIX, our Phase III study of AMX0035 in people with ALS, continues to progress as planned. In February, we announced that the study was fully enrolled with 664 participants. A reminder that there will be no interim data readout, and we expect data on the primary outcome and several secondary outcomes in mid 2024. Overall survival data will take another year or more to mature, and therefore won't be available until at least mid 2025. I will now turn the call over to Jim to review our financial results for the first quarter. Thanks, Josh. We're encouraged by the strong interest and demand we continue to see from the ALS community. From a financial point of view, our business is strong. Net product revenue were $71.4 million for the quarter, compared to net product revenue of $21.9 million for the fourth quarter of 2022, with the vast majority of that revenue from the United States. Gross to net adjustments were approximately 16% in the quarter, consistent with our expectations in the 15%-20% range. Inventory levels at the quarter end were as expected, with approximately two weeks of inventory in the channel at specialty pharmacies. Cost of sales were $5.3 million for the quarter and in the range of our expectation as sales volume grows. For modeling purposes, keep in mind that roughly 10% of the people on RELYVRIO are receiving it for free through either our interim access program or patient assistance program. Research and development expenses were $24.2 million for the quarter, compared to $21.5 million for the same period in 2022. These costs were primarily driven by our phase III PHOENIX study and added personnel as we support our programs. Starting in the second quarter, we expect R&D expenses will increase as we incur meaningful expenses to initiate our phase III pivotal study in PSP. You should expect R&D expenses to increase this year in a range of $30 million-$40 million per quarter as we move through the remainder of the year. Selling general administrative expenses, or SG&A, were $44 million for the quarter, compared to $26.3 million for the same period in 2022. We're investing in SG&A to support our strong commercial launch and expect our spend to settle in around $45 million per quarter for the remainder of the year. Overall, we're very pleased with our results this quarter, including achieving $1.6 million of net income just two quarters into our launch. I want to pause a moment on our overall financial results. With the strong demand for RELYVRIO driving near-term profitability ahead of our expectations, we want to reiterate our long-term financial goals. Driving top-line revenue as RELYVRIO becomes standard of care, growing profitability for our investors, and investing in a pipeline that has the potential to provide much-needed treatments for neurodegenerative diseases. We're well-positioned to build a profitable, financially strong organization for the long term. We ended the quarter with cash and short-term investments of $345.7 million and zero debt. We're currently in a position to fund the programs we discussed today without the need to raise additional capital. Finally, just a word on guidance. Last quarter, we gave some specific guidance about how the first quarter was going as we reported in mid-March. Since we're still early in the quarter, it's premature to provide a specific range of revenue guidance for the second quarter or for the full year at this time. The road ahead over the next few quarters is fairly simple. Execute on the launch and execute on our clinical and pipeline development programs. I'm excited about the progress that we've made and, most importantly, our ability to have a positive impact on the lives of so many people living with ALS. With that, I'll turn the call over to Justin for some closing remarks. Thanks, Jim. Thank you to everyone for joining us today. We covered a lot of exciting news. Our commercial ramp in the U.S. and Canada is proceeding very well, and we will know more on Europe later this year. We are expanding our clinical pipeline into PSP, a market that is likely as large as ALS, with a product that has already been shown to have a favorable safety profile in another disease and that has a demonstrated effect on relevant biomarkers. We achieved our first quarter of profitability in just the second quarter of our commercial launch in the U.S. We remain committed to our goal to help additional people with ALS and other relentlessly progressive neurodegenerative diseases gain access to new therapies. Now, we'd be happy to take your questions. Operator, please open the call up to Q&A. We will now begin the question-and-answer session. To ask a question, you may press star then one on your telephone keypad. If you are using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then two. At this time, we will pause momentarily to assemble our roster. The first question comes from Charlie Young with Bank of America. Please go ahead. Great. Thanks for taking the question. This is Charlie Young for Geoff Meacham. I have two questions, please. The first one is, you mentioned that the rate of the pace has moderate somewhat in terms of expectation going into perhaps the second quarter. Can you just provide more clarity on that? My second question, you know, just can you provide a little more details with regard the parent discussions that you have and kind of what's your expectation, you know, for the remainder of the year? Thank you. Oh, sure. This is Margaret. Thank you very much for your question. We continue to be incredibly pleased with our launch to date, and more importantly, our ability to bring a new treatment option and hope to the ALS community, especially given that this is the first product to demonstrate in a clinical trial a statistically significant benefit in both function and survival. Maybe if I could just reiterate a few key points. We ended the quarter with roughly 3,000 patients, again, double what we started with at the beginning of the quarter. That's about 10% of the 29,000 patients living with ALS. You know, not surprisingly, our net patient adds can't double forever. In Q2, we are expecting the number will be lower than what we delivered in Q4 and Q1. You know, I think more importantly, we continue to see significant interest and demand for RELYVRIO, both from patients and HCP, and we have a tremendous opportunity for us to grow, you know, both in depth and breadth at all the key ALS centers as well as the broader neurology community. The second question was on payers, and you know, again, we're very pleased with the progress we're making with payers with 50% of the covered lives to date having a published policy, and we expect that to only get better over the first half of the year. Thank you. The next question is from Michael DiFiore with Evercore. Please go ahead. Hey, guys. Congrats on the quarter, and thanks so much for taking my question. A few from me. The first question I have is a follow-up to the previous one. Now that more commercial payers have come on board, and given the fact that you said that the rate of net patient adds is beginning to moderate, could you perhaps provide any updated views on how big this initial bolus of patients could be? How long it could last before you achieve a steady-state trajectory of new starts? That's my first question. The second one is regarding the phase III PHOENIX trial. You mentioned that the OS data is gonna take at least a year or more to read out and that it's a critical endpoint. If you, if we assume conditional approval in the E.U. based on CENTAUR and the, are you expecting EMA to still maintain their conditional approval until the OS data finally comes in? Could there be a scenario when full E.U. approval could be granted based on just positive ALSFRS-R data alone? Thank you. Great. Thank you. This is Margaret again. Thanks for your question. Regarding the bolus, it's really too early to tell when the bolus will finish. What I can say is that we know in Q4 and in Q1, we did see that high level of demand due to the pent-up demand that we had. They were, quite frankly, even ahead of our expectations. We have begun to see the rate in new patient adds moderate. Again, I wanna reiterate, we have a tremendous opportunity for growth because even within the key accounts that we penetrated, and just to remind you of some of the metrics, we said 95% of all the key ALS centers have prescribed for at least one patient. You know, every account, you see one account, right? It's typical rare disease. Some accounts are highly penetrated, and some accounts have a great deal of room ahead of us to penetrate. We really have just started to get out into the broader neurology community. Again, we see tremendous growth ahead of us to, you know, serve all the remaining patients that are depending on us. Hi, Mike. This is Justin. Thanks for the question. You know, first just sort of the, you know, baseline for everyone. We continue to expect an opinion from the CHMP mid-year and a decision at the earliest in the third quarter. In the meantime, you know, our team is preparing for approval and launch. In terms of the PHOENIX trial and how that could affect the conditional approval. You know, the way that the EMA. First, you know, we won't know if it's a conditional approval or full approval until, you know, until we get the final decision. But our expectations is on a conditional marketing authorization. The way that that works is that you get approval, but with the condition that you do a follow-on study, and in this case, our expectation would be that it would be the PHOENIX trial. You have to renew that every single year until you meet the condition. The question is, you know, will we, you know, meet the condition depending on the ALSFRS-R functional results or the survival results? You know, that's really up to the regulators. What I will say high level, though, is that if we have a functional benefit, if we have a survival benefit, if we have both, it's the best data anyone's seen in ALS. I think either is a very positive situation. Ultimately, it's up to the CHMP and EMA. Thank you. The next question is from Corinne Jenkins with Goldman Sachs. Please go ahead. Hi. Good afternoon, everyone. Maybe a couple from us. I guess one, with more than 3,000 patients now on drug, up from the 1,300, even understanding that there could be some moderation, how long are you thinking it will take you from here to get to the 10,000 patients you had stated as a target for being stable on therapy at steady state? Maybe the second one for me is just given the clinical priorities that will soon be initiated, do you expect to maintain profitability through the balance of the year? The final one, just could you talk through the rationale of moving straight into a large phase III program in PSP without doing sort of like an earlier stage phase II or otherwise, and help us understand the relevant clinical endpoints for that indication? Sure, Corinne. I'll take the first question, and then I'll turn it over to Josh and Justin and probably Jim as well. Just, you know, we have not provided a timeline on how long it will take us to achieve the 10,000 patients. Our goal of getting to the 10,000 weighed patients really reflects our vision that RELYVRIO will become the most commonly used ALS medication, so basically standard of care. We feel that that's very achievable given it is the first product to demonstrate a benefit on both function and survival. I will tell you that right now we are heavily focused on the launch execution with the goal of getting there as quickly as possible because patients are depending on us. maybe I'll. Yeah. Turn it over to. Yeah, go for it, Jim. Sorry. Yeah. Yeah, sorry, Josh. I'll take the next one on profitability. You know, we decided not to guide at this stage, Corinne. You know, that will include also not guiding on profitability because essentially, obviously that's guidance. I think you all can see the math in terms of the, you know, the hydraulics in our P&L. As long as we can grow revenue faster than we grow expenses, we'll be able to maintain that profitability. I think importantly for us, longer term, it just really highlights the opportunity we have in this business and how unique the ALS market is. Ultimately, I think we have to recognize it's the need of the patients that's driving this launch and the fact of, you know, the matter of the data that we have with RELYVRIO. We're going to continue to focus on our long-term goals, as I tried to outline in the prepared remarks, making RELYVRIO the number one ALS therapy. That's first and foremost. Driving long-term profitability for our investors, right? That's how we get to be a sustainable business long term. I think that's also another thing that differentiates us from a lot of other companies out there. We don't need to continue to go back to the market to fund our business because of how well the launch is going and the interest that we're seeing in the community. Also we're going to invest in our pipeline because there's a real need in neurodegenerative diseases. I think we can do all three, which is what makes me so excited to be here at Amylyx at this time. Josh, back to you. Thanks, Jim. Talking about PSP, I think the first thing I should share is over the last several years, we've gone through a process internally to try to select those indications that are highest priority for the company. I outlined some of the things that we look at for that. Most importantly, PSP met all of the criteria that we were looking at for an indication to prioritize as a company. We already have shown in a randomized placebo-controlled study, data against what is thought to be the primary pathology of progressive supranuclear palsy. I think that's part of what's driving our excitement, as well as the excitement we're hearing from the KOLs and the community about this indication. Just as an add too, there's also some preclinical data that's also supporting and making us excited here. I think it's that constellation of factors that makes us really excited to go into this PSP study. Great. Thanks, all. The next question is from Neena Bitritto-Garg with Citi. Please go ahead. Hey, guys. Thanks for taking my question, and congrats on the update. Just in terms of, you know, trying to figure out this bolus, can you talk a little bit about what you're seeing in terms of start forms versus net adds? I'm just curious if you can talk about the trend you're seeing there. Then give us any color on duration of therapy so far or, you know, any dropouts that you're seeing. That'd be great. Thanks. Yeah. We're not providing any guidance on the number of patients for the quarter. Again, I'll just go back to, you know, we think our net patient adds, you know, they can't double forever. We'll be lower in Q2 than we've been able to deliver in Q4, Q1, because we believe that, you know, that was the initial pent-up demand. Again, we don't know, you know, when that bolus will be over, so it's hard for us to really give any guidance on that. In terms of duration of treatment, it's really too early in the launch to give that. I mean, the first patients who started on therapy, were basically at the end of October, beginning of November, so they really haven't been on therapy long enough for us to give, you know, any clarification there. In terms of discontinuation rates, that's sort of similar as well. People just haven't been on therapy long enough. I can tell you that the general trends that we're seeing are kind of in line with what we saw with CENTAUR. Nothing is, you know, out of line there. Just as a reminder, with CENTAUR, we're seeing roughly about a 25% discontinuation rate at six months. Again, patients haven't really been on therapy for six months yet. We're gonna continue to monitor that very closely. Got it. That's helpful. Thank you. You're welcome. The next question is from [audio distortion] Marc Goodman, you're on the podium right now. Oh, hey, sorry. I couldn't hear. Can you talk about the mechanism for AMX0114? And then second, just the data support the Wolfram study, and the reason, the rationale for moving there? Thanks. Sure. First on AMX0114. AMX0114 is an Antisense Oligonucleotide Targeting Calpain- 2. There's a pathway called Wallerian degeneration that's been around since the 1850s, which is the pathway whereby a neuron will destroy its own axon in response to injury or stress. You know, that pathway, over the last 150 years, the pharmacology has become pretty clear on what proteins need to be activated and otherwise for that axonal degeneration to occur. You know, what you'll find digging into the Wallerian degeneration pathway is that Calpain- 2 is one of the key proteins involved in that. In addition, there's been preclinical studies with both, kinda knock-in models and knockout models that have shown that Calpain- 2 inhibition can be effective in several animal models of ALS. Finally, there's a lot of evidence out there linking Calpain- 2 to different ALS biomarkers, including TDP-43. Turning to Wolfram. Wolfram, as we shared in the last conference call, is a space we've done at least four years of preclinical work together with Washington University and Dr. Fumihiko Urano there. Broadly, those experiments studied both, cellular models of the disease as well as an animal model of the disease. Much of that data is published in Journal Clinical Investigation Insight. Broadly, what we saw was some degree of rescue of the phenotype, both in the cellular models as well as in the animal model. I think that was the data that got us really excited to go forward there. Thanks. The next question is from Graig Suvannavejh with Mizu... I'm sorry, Mizuho Securities. Please go ahead. Hey, good afternoon. Thanks for taking my questions and congratulations on the quarterly results. I've got two questions, if I could. First is more commercially related. The second's pipeline related. On commercial, do you have any sense in these early days kind of how the drug is being used in patients? By that, do you have a sense of distribution of its use, whether what percent is in monotherapy versus some combination setting versus a potential triple combination? Any thoughts there would be great. On the pipeline, I just had a question on the new phase III PSP study, maybe it's a twofold question. First, you know, in light that, you know, there have been attempts in PSP in the past, you know, one was with an anti-tau antibody, is it really just the movement on markers that gives you confidence that it'll be able to work in PSP? Is there some other elements? Maybe the part B of that is the strategy more biomarker driven in terms of kind of the momentum we're seeing in the neurodegenerative space and how FDA seems to be very open and receptive to biomarker-driven strategies? Thanks. Yeah. I'll take your first question. I would say that regarding the, you know, use of whether or not it's monotherapy or a combination therapy, it's really a broad mix from single use of RELYVRIO to combination therapy with all three available products. We're really seeing the utilization in a very broad patient population. We continue to see patients that have been diagnosed with this disease for many years, get prescribed this drug, as well as newly diagnosed patients. We define newly diagnosed patients as patients who have been diagnosed in the last six months. I would say that, you know, from an ease of access perspective, some physicians may start first with Riluzole, and then they'll switch to or add RELYVRIO to Riluzole just because again, it could take, you know, it was taking up to 30 days last quarter or in Q1, for a patient to get access to the drug from the time to enrollment on average. We expect that to continue to improve as more policies come on board. Yeah. Graig, thanks for the question on PSP. This is Justin. I mean, first I would say, you know, I think the PSP community and especially the key opinion leaders are really excited about this. I mean, in RELYVRIO, we have an oral, safe drug that's FDA approved for another neurodegenerative disease. In terms of the rationale for PSP, preclinically, we've shown that AMX0035 protects against neurodegeneration. PSP is a rapidly progressive neurodegenerative disease. Clinically, we showed the very significant reductions in tau in our Alzheimer's study. While yes, there have been antibodies against tau that were unsuccessful in PSP is still a tauopathy. That's the canonical protein associated with it. In terms of the study design, you know, we're not gonna get into that today. I think it's really all of the above that makes us and probably more importantly, the key opinion leaders so excited about the study in PSP. We'll continue to share more on that. We're really excited about starting that study. Thank you. The last question comes from Ananda Ghosh with H.C. Wainwright. Please go ahead. Hi guys. Congrats on the quarter. I have two questions on PSP. The first one is how similar is PSP with ALS, you know, concerning the downstream degeneration pathway? The second is, you know, we never got to hear about the mechanism with which AMX0035 impacts the tau in your phase II trial, which is CENTAUR. Is there any insight? Yeah. Maybe first on PSP and ALS and their degenerative pathways. You know, I think for both of these diseases, there's, you know, still a lot of research into exactly, you know, all of the etiology and pathology. I think our view and the literature, you know, there's a lot of literature on this as well, is that both diseases see significant cell death related to endoplasmic reticulum and mitochondrial related pathways. Which is what we developed AMX0035 to target. In terms of the pathways whereby AMX0035, you know, may affect tau, I think there's a lot of literature on the link between tau and endoplasmic reticulum stress. That's something that we've focused on there. This change in tau we've seen both in preclinical models, including ones that are published, as well as in our phase II Alzheimer's randomized placebo-controlled study. You know, we feel that that's a pretty robust and, you know, consistent finding. Great. Thanks. Thank you. There are no further questions at this time. I'll turn the call back to Mr. Klee for final comments. Thank you all very much for joining us this afternoon. You know, we covered a lot of exciting news. You know, our commercial ramp in the U.S. and Canada is proceeding really well. We're expanding into another clinical indication, which has a huge unmet need and has a market that is probably as likely as large as ALS. With a product, as we said, that's already been shown to be safe and well-tolerated in a neurodegenerative disease, as well as show quite significant reductions in tau. You know, maybe one other thing we only talked on briefly, but we achieved our first quarter of profitability in just the second quarter of commercial launch in the U.S., which we're really excited about. We're a mission-driven company. We have many more people to help and many more people to help around the world, both with ALS and we hope with other neurodegenerative diseases as well. Achieving profitability is what's gonna allow us to have a sustainable business, to keep moving forward and keep helping more and more people with neurodegenerative diseases. Thank you all very much for joining us and for your support, and we hope you have a great rest of your day. The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
