Sheldon Koenig -- President and Chief Executive Officer

Thank you, Tiffany, and good morning, everyone. We are excited to be here with you today to recap the first quarter of what will be a transformational year for Esperion and reaffirm our goals for 2022. Over the past few quarters, Esperion has outlined a strategic vision to position our company for long-term growth and success. And we continued to execute both commercially and in the clinic to attain our goal of becoming an innovative cardiometabolic leader.

As part of that strategy, in 2021, we streamlined our operational structure to focus our resources on driving the consistent growth of our commercial products, NEXLETOL and NEXLIZET, and the advancement of our ongoing unprecedented CLEAR Outcomes trial, leading up to the planned top line readout in the first quarter of 2023. Now during the remainder of 2022, we remain steadfast and are focused on delivering these objectives. I'd like to begin with a brief overview of the commercial progress of NEXLETOL and NEXLIZET. To recap the last quarter, year-over-year demand for our medicines grew 56.7% in the first quarter, with U.S.

net product revenue of $13.4 million, up approximately 109% from the same period of 2021. These robust results were the culmination of the enhanced product positioning and refined patient support programs we initiated in 2021 and continue to improve. We have enhanced our targeting efforts even further to identify and optimize new physician targets using the contract sales organization we began deploying this year, concentrating on physicians who will help drive more frequent utilization. Our partners, Daiichi Sankyo Europe, continue to actively grow NILEMDO and NUSTENDI in their European territory and have cumulatively treated at least 52,000 patients through the first quarter of 2022.

Our products have demonstrated significant traction in the European market with a stronger launch trajectory than PCSK9 inhibitors. And we continue to believe that the accessibility and convenience of an oral medication will provide a significant improvement to the quality of patient care. I am also pleased to report that this quarter, we have achieved year-over-year cost savings of 32% in our operational expenses compared to the first quarter of 2021. This represents effective execution of our transformative plan announced in the fall.

We are approaching 95% MACE accumulation in our unprecedented CLEAR Outcomes trial and expect to reach 100% of MACE by the end of the year, with top line data in the first quarter of 2023. As you all know, this is a critical priority for Esperion. And our entire team is focused on the task of ensuring a high-quality trial close and proper data collection. With an estimated 41 million patients impacted by hypercholesterolemia globally, and 18 million patients in the U.S.

alone, it is more crucial than ever to identify and treat patients who are unable to achieve their LDL-cholesterol goals with existing treatment options. Presently, an estimated 70% of patients are not at guideline recommended LDL levels despite the numerous treatment options in the cholesterol management landscape. Other cardiovascular drug manufacturers also see the significant value waiting to be realized in cholesterol management. By 2026, annual worldwide revenue in the lipid market is projected to exceed $11 billion.

Esperion remains committed to its mission of providing oral accessible therapies to address cardiovascular risk. We recently announced support for a collaborative study with a large integrated and learning healthcare delivery system in Northern California to study the effects of NEXLIZET in reducing LDL cholesterol following a heart attack. These data will add to the extensive body of evidence supporting the clinical value of NEXLIZET. Now I'd like to turn the call over to JoAnne for an overview of our ongoing clinical activities and data presentations.

JoAnne?

JoAnne Foody -- Chief Medical Officer

Thank you, Sheldon. I'd like to begin by emphasizing the severe impacts of cardiovascular disease on life expectancy in the U.S., particularly in recent years during the COVID-19 pandemic. Despite the staggering losses from COVID, heart disease remains the leading cause of death in the United States. In fact, heart disease and stroke mortality rates have risen sharply since the onset of the COVID-19 pandemic.

Age adjusted death rates from heart disease increased 4.1% from 2019 to 2020, contributing to a loss of life expectancy of almost two years during its period. It is important to highlight that 85% of all cardiovascular disease tests are attributed to atherosclerotic cardiovascular disease, driven in large part by high LDL cholesterol. These sobering statistics reaffirm the importance of Esperion's mission to bring transformational oral therapies to patients. They reaffirmed added urgency to our ongoing clinical and medical and commercial efforts tackling chronic diseases and supporting our bempedoic acid franchise.

We are also leveraging our scientific data, patent estate and other unique mechanisms of actions to advance a pipeline of novel compounds, which we expect to be extremely competitive in the multibillion dollar lipid market projected for 2026. We will have more to share with you on our oral PCSK9 and next-generation ATP citrate lyase inhibitors platform by the end of the year. Our unprecedented CLEAR Outcomes trial continues to progress as we expected and represents the most modern outcome data set collected in today's evolving medical care environment. As a reminder, CLEAR Outcomes is a 14,000 patient randomized outcome trial, one of the largest outcome trials of nonstatin therapies yet.

This study will assess bempedoic acid's ability to reduce incidents of adverse cardiovascular events in a unique patient population that is unable to adequately address their LDL-cholesterol risk with the current standard of care. The study was developed in partnership with experts and regulators and is headed by world-renowned trialists, Dr. Steven Nissen and a team of international experts. The trial is approaching 95% of its required major adverse cardiac events.

Our deeply committed and experienced team expects 100% accumulation of our MACE-4 events in the second half of this year and a top line readout first quarter of 2023, which is now less than one year away. A positive cardiovascular outcome trial in 2023 not only has the potential to expand our current labeled indication, but also to be practice-changing for physicians and paradigm shifting for millions of patients around the world, advancing Esperion's mission of making cardiovascular risk reduction more accessible and convenient for all. A positive outcome study in the ensuing label has the potential to make bempedoic acid the only oral LDL-lowering therapy since statins to be indicated for CV risk reduction. We also continue to actively present our data at scientific meetings.

We recently announced multiple presentations on NEXLETOL at the American College of Cardiology's 71st Annual Scientific Session. Additionally, we announced multiple publications of data in peer-reviewed journals, all supporting the safety and efficacy of bempedoic acid in diverse patient populations and highlighting patients most likely to benefit from our therapies. As you can see, Esperion has made a commitment to the science of lipids to advancing our understanding of bempedoic acid as a key oral therapy to address LDL cholesterol and executing CLEAR Outcomes, while progressing our pipeline of oral compounds to address cardiovascular and cardiometabolic disease. I'll now pass it back to Sheldon for additional commentary on our quarterly results.

Sheldon?

Sheldon Koenig -- President and Chief Executive Officer

Thank you, JoAnne. Earlier today, we issued a press release containing our financial results for the first quarter, which is available on our investor website. U.S. product revenue for the first quarter ended March 31, 2022 was $13.4 million, up approximately 109% year over year.

Royalty revenue for the first quarter ended March 31, 2022 was $1.1 million, up 83% year over year. Combined royalty and partner revenue of $5.5 million for the first quarter ended March 31, 2022 grew approximately 244% year over year, driven by launches in Belgium, Switzerland and the Netherlands, and continued growth in previously launched territories. We expect our partner to continue rolling out NILEMDO and NUSTENDI to new geographies. Finally, total revenue for the first quarter ended March 31, 2022 was $18.8 million compared to $8 million for the first quarter of 2021, an increase of approximately 135% year over year.

Turning to expenses. Gross margin decreased as a percent of revenue, largely driven by an increase in the purchase of inventory from our international partners, which has a lower margin than our U.S. sales. We expect this to improve over the year as shipments reached steady state compared to the first half of 2022.

R&D expense for the first quarter was $24.3 million, a decrease of 13% year over year, primarily related to a reduction in alternative supply manufacturing and compensation costs. SG&A expense was $30.4 million for the first quarter, a decrease of 50% year over year or 36% year over year when adjusting for onetime legal expenses of $13.3 million in Q1 2021. These decreases reflect savings from the transformation for long-term success plan implemented in Q4 of 2021. As of March 31, 2022, cash, cash equivalents, restricted cash, and investment securities available for sale totaled $268.5 million compared with $309.3 million on December 31, 2021.

We are well capitalized and anticipate that our cash runway extends through the anticipated completion and readout of the CLEAR Outcomes trial and continues to fund continuing operations for the foreseeable future following those results. Our operating expense guidance for the full year 2022 remains unchanged. We continue to anticipate full year 2022 R&D expenses to be between $100 million to $110 million and SG&A expenses to be between $120 million to $130 million. These estimates are inclusive of approximately $25 million of noncash stock-based compensation expense expected to be incurred during this year.

We recently filed a $400 million shelf registration statement after our previous registration statement expired in February upon the filing of our annual report. This new filing preserves our financial flexibility for the future, but does not change our belief that we are financed through the readout of the CLEAR Outcomes trial and for the foreseeable future beyond that. That said, we view our stock price as extremely depressed at current levels and continue to work diligently to maximize shareholder value. In closing, I am proud of what our team has accomplished in positioning our organization for the future in alignment with our ever important mission of reducing cardiovascular risk today and in the future.

Cardiovascular disease continues to be the No. 1 killer across the world. And it is critical for patients to be able to manage their cholesterol levels effectively. We believe NEXLETOL and NEXLIZET has significant potential to help patients reduce their risk of heart attack and stroke.

And we look forward to the top line results from our CLEAR Outcomes trial to provide further insight into the benefits our medicines can provide in key underrepresented patient groups within today's medical care environment. We have a solid strategy in place to execute on our planned activities, and we look forward to providing additional update on what will be an exciting and productive year for us. Thank you all for joining today and for your continued support and interest in Esperion. Operator, we are now ready for Q&A.

Questions & Answers:

Operator

Thank you. [Operator instructions] Our first question comes from the line of Michael Yee of Jefferies. Your question, please. 

Unknown speaker

Hi. Good morning. This is [Inaudible] on the line for Mike Yee. Thanks for taking my question and congrats on a strong quarter.

Maybe two for me. First of all, could you comment on the U.S. sales trajectory appreciating there's a recent increase in price? And can you comment on the volume as well? Do you see the volume is accelerating into second quarter as well and maybe beyond or do you see any impact from pandemic? I guess the second one is, could you clarify how good your CVOT data needs to be to get the milestone payment from Daiichi? Specifically, is there a bar for efficacy? And if you could talk about what are the scenarios for the data to drive what kind of payments? And how confident are you in each of the scenarios? That would be very helpful. Thank you.

Sheldon Koenig -- President and Chief Executive Officer

Great. Well, first of all, let me start with your second question, and I'll turn it over to Eric Warren for your first question as it relates to sales, etc. So again, thank you for your message. As it relates to milestone payments for Daiichi Sankyo, we have the ability to receive up to $300 million from Daiichi Sankyo upon the conclusion of the CLEAR Outcomes study and then that data being included into the European label.

I just want to reiterate again the timing of the top line. This is again, the top line will be in the first quarter of 2023. Then the data will be reported at a major meeting. But of course, we'll also be filing the data with regulatory committees.

But that is the milestone and that's how it works with Daiichi Sankyo. Eric?

Eric Warren -- Head of Sales and Marketing

Yes, absolutely. Thanks for the question. With regards to growth from a volume perspective, we saw about a 6.5% of volume increase. So that's consistent with the mantra that we've provided of delivering consistent growth throughout the year.

So that will be the mission for the team. We're on track to do so. And then, of course, with CLEAR Outcomes, we unlock the exponential growth.

Unknown speaker

Great. Thank you.

Operator

Our next question comes from Serge Belanger of Needham. Your line is open.

Serge Belanger -- Needham and Company -- Analyst

Hey. Good morning. Just a couple of questions for me. The first one, on the contract sales force effort.

I think you mentioned you've been able to target some new physicians. So maybe just describe the effort and whether it can be scaled up as you see success with it. And then secondly, regarding the collaborative study with the healthcare delivery system in Northern California, could that end up in a label extension or it's more of a move to for a guideline positioning down the road? Thank you.

Sheldon Koenig -- President and Chief Executive Officer

Eric?

Eric Warren -- Head of Sales and Marketing

Yes. Good morning, Serge. So the CSO team, as you know, is in pilot form. We're leveraging the CSO to do three things for us: cover the white space; cover vacancies as they arise; and to create overlapping coverage for some targeted HCPs where we feel like it's essential to have dual coverage.

So far, so good. And we're seeing the CSO able to get in, able to have meaningful discussions. We deployed the team late in January. So still early, but encouraging so far.

And you're absolutely right. We've got the ability to scale depending upon the returns that we see, also depending upon the environment that we operate in. So so far, so good, but still in pilot and early phase.

JoAnne Foody -- Chief Medical Officer

Serge, this is JoAnne. Thank you for your second question regarding the system in Northern California. This is actually a pragmatic study that really is looking at the ability of NEXLIZET to improve LDL levels in patients post heart attack. To your point, it would be unlikely that this would indicate a label expansion.

But importantly, this is significant for practicing clinicians and particularly for a system-level approach to allow the utilization of NEXLIZET at time of discharge from an acute coronary syndrome or heart attack. So we believe that that will have important practice-changing implications, but not a label changing one.

Sheldon Koenig -- President and Chief Executive Officer

And continues to add to the wealth of information already out there as it relates to bempedoic acid. So excited about that. Thanks, JoAnne. Thank you, Serge.

Serge Belanger -- Needham and Company -- Analyst

Thanks to you.

Operator

Our next question comes from Jason Butler of JMP Securities. Your line is open.

Jason Butler -- JMP Securities -- Analyst

Thanks. Thanks for taking the questions. Just a couple for me. Can you -- I guess on the CLEAR Outcomes study.

Can you just give us an update on the progress you're making with adjudicating events and just preparing for database lock-in in the patients where you already have the events accumulated? And then a commercial question. Can you speak to the dynamics of growth between adding new physicians versus new physicians writing more prescriptions in the quarter? Thanks.

JoAnne Foody -- Chief Medical Officer

So Jason, thank you for your question. On the CVOT, we are continuing to adjudicate events essentially in real time. Really staying up to speed, with our nearly 95% of events for our MACE-4 as well as well over now 100% of the MACE-3 events. We will continue to do that.

Importantly, we are beginning to start end-of-study visit for the entire global study, which includes bringing in over 28,000 end-of-study visits, two per the 14,000 patients, and these are progressing, if anything, ahead of schedule. So we're continuing to look toward top line results Q1 of 2023. And stay tuned, we're less than a year away.

Eric Warren -- Head of Sales and Marketing

And then, Jason, with regards to your commercial question, it's Eric, so we're seeing both. So new HCPs are coming in to the mix. This is driven by some of the digital activity. As you're aware, we've got a three-pronged approach.

We're leveraging digital. We're leveraging our personal promotion, and we're leveraging peer-to-peer. We're also seeing increased depth. That depth comes as a result of the personal promotion and our representatives encouraging HCPs to prescribe deeper levels of the product.

So we've seen some meaningful gains in both of those dynamics.

Jason Butler -- JMP Securities -- Analyst

Great. Thanks for taking my questions. 

Operator

Our next question comes from Jessica Fye of J. P. Morgan. Please go ahead.

Jessica Fye -- J.P. Morgan -- Analyst

Hey, guys. Good morning. Thanks for taking my questions. Following up on one of the prior questions.

With the MACE accumulation and CLEAR Outcomes nearing 95%, is it reasonable to assume the trial could reach 100% accumulation by early in the third quarter? Second question is just hoping for a little more color on where you're seeing NEXLETOL and NEXLIZET use today. Is it more so in statin-intolerant patients or more so in those taking statins who need some additional LDL lowering? And then last question, gross net looks like they improved this quarter. Is this quarter's gross net a good run rate for the rest of the year? Or could we think about continued improvement there?

JoAnne Foody -- Chief Medical Officer

So Jess, thank you so much for your question. With respect to the CVOT, certainly, we could consider having that 100% in earlier in the second half of the year. However, that will depend on the events. The key though is that there still is a significant amount of time required to close out the study.

But we are confident that the study will be closed out, including all those end-of-study visits by the end of the year with top line results Q1.

Eric Warren -- Head of Sales and Marketing

And with regards -- Jess, it's Eric, to the types of patients. So maximally tolerated statin, ASCVD still require additional LDL-C reduction, it's the primary population that aligns with the label, that aligns with the prior authorization criteria. And of course, we remained very encouraged by CLEAR Outcomes and the potential to expand that population.

Sheldon Koenig -- President and Chief Executive Officer

And then, Jess, regarding your question on GTN. Even going back to this time last year, the one thing that we've been consistent with is the fact that we will look for ways to improve our gross to net. So that's something that is continuous. We're always continually to look for ways to improve our GTN.

I think I mentioned this before, we have weekly meetings that concentrate on this. And we'll continue to update you as we go through the quarters on our progress. But it's obviously a focus and a priority. And we have shown notable improvement since last year, and we'll continue to do so.

Jessica Fye -- J.P. Morgan -- Analyst

Great. Eric, can I just follow up on that question? Recognizing that statin-intolerant patient is on their maximum tolerated dose of statin even if it might be no statin, I was hoping you could kind of within the label, break out, maybe we can phrase it as which patients are on moderate to high-intensity statins versus low or no statin as their max tolerated statin?

Eric Warren -- Head of Sales and Marketing

Yes. I'll just say the bulk of the focus of our promotion has been on those patients that have tried statins. They're not able to get to goal, and they have the underlying ASCVD. There's some interest from an HCP level in those physicians -- from those physicians that are able to push the statin dose at higher levels.

But that's not the area we're encouraging, that just creates challenges from a prior authorization perspective. JoAnne?

JoAnne Foody -- Chief Medical Officer

And Jess, if I could just provide some context. I think that in general, in the U.S. population, even in ASCVD patients, that the majority of statin use is still in that lower intensity. Lipitor 10 is still the most commonly prescribed, and we're seeing that.

I think if we switch -- our label in the U.S. does not allow technically for statin intolerance, right? Although, to your point, you could say that maximally tolerated with zero. However, in Europe, and part of the reason for their success is that they don't have maximally tolerated in their label. And in their population, they do target, to your point, more consistently the statin-intolerant group of patients.

And then lastly, we see that the CVOT as really being that opportunity to remove the maximally tolerated from our label and give us a much broader expansive opportunity irrespective of statin.

Jessica Fye -- J.P. Morgan -- Analyst

Thank you.

Operator

Thank you. Our next question comes from Jeff Hung of Morgan Stanley. Please go ahead.

Jeff Hung -- Morgan Stanley -- Analyst

Thanks for taking my questions. You talked about the goal of driving consistent growth up to the CVOT results. Can you talk about any additional levers that you may have to further drive growth ahead of the Outcomes data? And then for the next-gen ACL inhibitor, given the broad therapeutic application, how do you think about prioritizing the different indications you'll pursue? Thanks.

Sheldon Koenig -- President and Chief Executive Officer

Thanks, Jeff. Yes. So with regards to consistent growth, obviously, the environment that we play in has a factor as was the COVID environment. We're seeing greater access, it's a good sign for us in our ability to drive growth.

There is increased level of awareness that we're starting to see. As the world opens up, we're starting to see, for example, live Congress engagement. We've just recently completed our ACC Congress where we think that there was somewhere in the neighborhood of 8,000 to 9,000 live attendees. Obviously, the team had a full suite of activities.

So as the world continues to open up, that creates more momentum for us. Obviously, we're doing our 3-pronged approach. From a digital perspective, we're spending more and more time. So I expect that to continue to bear fruit as well.

Also, from a managed care perspective, maybe I'll let BJ comment on some momentum that we've got with regards to managed care.

BJ Swartz -- Chief Strategy Officer -- Analyst

Yes. From a payer perspective, we have a favorable coverage from a commercial standpoint. And we've done a segmentation analysis down to each geography level showing the opportunity for pull-through. In addition to that, we are also working with very specific IDNs on demonstration projects from an HEOR perspective as well as really embarking into the long-term care market as well, which should provide incremental growth as well.

Sheldon Koenig -- President and Chief Executive Officer

And I would just add, I think that speaks to partnership. We've talked about a partnership with a Northern California institution as well. You've seen a number of publications that have also been growing out over the past few weeks and months. And these are all ways to continue to gain more awareness as we continue to march toward the completion of CLEAR.

And JoAnne, do you want to speak to...

JoAnne Foody -- Chief Medical Officer

Absolutely. So Jeff, thank you so much for the question on our next-generation ATP citrate lyase platform. As you're aware, we believe the mechanism is one that has opportunity across multiple disease states beyond cardiovascular and moving into cardiometabolic and even oncology. As you've stated, we are continuing to refine potential opportunities in disease states with consideration of diseases such as NASH, kidney disease, as well as cardiometabolic and even oncology with diseases like hepatocellular carcinoma.

We are doing this in a very refined way, leveraging data science, analytics, big data to really help us understand where the opportunities might lie, not only from a medical clinical perspective, but also from a commercial one. And we will be amassing a group of international experts to advise us in this so that we can really ensure that we're making the right decisions with respect to the platform, with respect to the disease and with respect to the investment in those areas. But really very excited for that platform and the opportunity to expand to a much broader patient population with ATP citrate lyase inhibitors. Stay tuned.

We'll have more information for you at the end of this year as we plan a research and development day.

Jeff Hung -- Morgan Stanley -- Analyst

OK. Thank you.

Operator

Our next question comes from Joseph Thome of Cowen. Your line is open.

Joseph Thome -- Cowen and Company -- Analyst

Good morning and thank you for taking my questions. I guess as you look across 2023, we'll have the data. Then you'll have the incorporation into treatment guidelines and then also hopefully the updated label. I guess when you talk to your physicians, what did they watch and respond to the most? I guess which one of these events could potentially cause the largest increase in scripts? And then second, I guess when you do talk to physicians, do they say we want to prescribe bempedoic acid, but we want to wait and see Outcomes data? How does that conversation go? And any idea on reorder rates would be helpful.

Thank you.

Sheldon Koenig -- President and Chief Executive Officer

Joe, you were fading at the end. We got the part of what the folks want to see for Outcomes. We got your second question, but the last part kind of faded out.

Joseph Thome -- Cowen and Company -- Analyst

Yes. Just on reordering rates, once patients come on, are they staying on therapy?

Sheldon Koenig -- President and Chief Executive Officer

Yes, yes. JoAnne, do you want to?

JoAnne Foody -- Chief Medical Officer

So Joe, thank you for the question. So exactly as you've laid out, right, we anticipate that 2023 will have our top line results. Ultimately, we would anticipate a presentation and publication of the results early within the year and then label inclusion 2024. Over that time, what we would likely see and what we anticipate is that there will be those have been awaiting Outcomes, and if you will, voting with their feet and waiting for that.

We anticipate that those individuals will start to prescribe well before we have data in the label. And importantly, we anticipate the guidelines would be updated midyear based on our best understanding of the guideline process within the U.S. and what we anticipate for prevention guidelines. Understand that bempedoic acid is already in a very significant number of guidelines at present, but we do have that asterisk that says we don't have Outcomes, but we anticipate those would be removed.

Clearly then, the label is one that starts to give us greatest value, of course, with payers. However, we'll be talking with payers well before and have a strategy to discuss the data with them before and would anticipate some wins well before the label. And Eric, did you want to speak to the prescriptions?

Eric Warren -- Head of Sales and Marketing

Yes. Yes. Yes. So thanks so much for the question.

So with regards to the growth, yes, it comes from a few sources. So penetration, yes, obviously a greater depth of penetration. It also comes from access, to JoAnne's point, eliminating the maximally tolerated statin and eliminating the dependence upon the secondary prevention or the focus on ASCVD patients. We recently did some significant quantitative research.

And we confirmed that both of those components or those levers are unlocked with CLEAR Outcomes. So significant opportunity with CLEAR Outcomes on those two thresholds.

Joseph Thome -- Cowen and Company -- Analyst

Great. And then just on the reorder rates, are patients staying on therapy once they come on?

Eric Warren -- Head of Sales and Marketing

Yes. From an adherence perspective now, our adherence is very consistent with chronic oral therapies. So we're focused on driving new patients, but we're also focused on maintaining existing patients on therapy. The teams coming up with a program called Next Step, which will provide a suite of resources to further improve that rate of adherence, but very consistent with current chronic oral therapies.

Joseph Thome -- Cowen and Company -- Analyst

Great. Thank you very much. 

Operator

Thank you. Our next question comes from Tom Shrader of BTIG. Your line is open.

Unknown speaker

Hey. Good morning. This is Sung calling in for Tom. So just one question for me.

So given the recent publications showing the long-term durability of bempedoic acid, I was just wondering if you guys have any plans to perform additional studies as a combination therapy with either drug that's approved or in the development to see how much additional LDL lowering you guys can achieve. Thank you.

JoAnne Foody -- Chief Medical Officer

So good morning and thank you for the question. This is JoAnne. So as you mentioned, we've just recently published our open-label extension study demonstrating that consistent benefit. I think right now, we are waiting for CLEAR Outcomes.

And that will really then tell us the opportunity of whether or not we pursue additional studies with respect to combination therapies or the like. Importantly, in our discovery phase, as you know, we already have an oral PCSK9 inhibitor as well as the next generation of bempedoic acid. And I think all of these programs will be informed based on CLEAR Outcomes as well as the opportunity that presents for combination therapy. I think in the field, there's a growing importance of early combination oral therapies to address cardiovascular risk.

And I think that we are well positioned with our existing therapies, NEXLETOL and NEXLIZET, and have the opportunity, as you say, to potentially combine with other oral therapies to bring those to patients.

Unknown speaker

Great. Thank you.

Operator

Thank you. Our next question comes from Paul Choi of Goldman Sachs. Please go ahead.

Paul Choi -- Goldman Sachs -- Analyst

Thank you. Good morning, team. And thanks for taking our questions. Congratulations on the progress.

Sheldon, I was wondering if you could maybe just elaborate on your earlier comments regarding the commercial environment? And could you maybe just give us a little more color on as how you're seeing and your sales force is seeing return to office in terms of patient visits and how much in person or in face time your contract sales force is able to gain versus, let's say, the last couple of quarters in terms of direct interaction, in-person interactions with prescribers?

Sheldon Koenig -- President and Chief Executive Officer

Thanks, Paul. Yes, I'll take a start and then I'll then also turn it over to Eric. So I think what we've been seeing, and I know even personally from having been to a doctor's office the past couple of weeks, I think patients are definitely coming back to the office. We're hearing -- I was just speaking to one of our business managers who Eric had a meeting with all of them last week in Philadelphia, they're even seeing large areas or large practices open up again and welcome patients in.

So I still think there's a bit of a balance where people are doing telehealth, etc. But for the most part, patients are starting to return back to the office. Our representatives are actually able to gain access where these physicians are open. And I know in the news, there's more talk about variants, etc.

But I think also, everyone, I'm not an expert in this, is getting used to the ability to, OK, deal with this and get their healthcare addressed. So I don't see the environment being like what it was a year ago or even a year before that. So that would just be my overall comment. And Eric can talk about some specific examples.

Eric Warren -- Head of Sales and Marketing

Yes. So Paul, good to hear your voice. So the CSO team is a virtual team, again, a small team. Their focus is on engaging virtually, which is good.

It gives us flexibility for times when the environment may not be as friendly. Our personal promotion, the Esperion team, I would say it's about 95% in-person, 5% virtual engagement. And rather than being a kind of an or, it's an and. I really want the team to leverage both virtual and in-person to extend their reach, to also improve their frequency.

Let's see. From an environmental perspective, as I mentioned earlier in the call, congresses are starting to open up. I was encouraged by ACC. Obviously, it wasn't ACC of 2019 from an attendance perspective, but it was a step in the right direction.

We're also seeing a lot more live in-person peer-to-peer via speaker programs, such as larger programs or smaller pure discussion groups that we conduct. So I remain encouraged by the work that the team is doing. But I do think that we have the right model. And not being completely dependent upon any pillar but having a balanced promotional pillar is going to be really important for us going forward to flex as the environment changes.

Paul Choi -- Goldman Sachs -- Analyst

OK. Great. Thanks for that, Eric. And maybe just one for JoAnne, which is just, as you will debut a little bit more on your oral PCSK9 program, could you maybe sort of comment on how you think about potential development here relative to the Merck MK-0616 program, which had some data last year at AHA, I believe? They're showing like 60% to 70% type LDL reduction in patients.

And just how you think about development there and potential areas of focus for differentiation? Thank you.

JoAnne Foody -- Chief Medical Officer

Yes. So Paul, thank you so much. So we're excited. As you mentioned, we do have this oral PCSK9 and we're well aware of the Merck data, which was very impressive.

Given that, however, we believe that the scaffold that we have and the approach which is allosteric inhibition allows us for a smaller molecule with better COGS. And I think as we think about development, really the key with an oral PCSK9 is obviously efficacy, which we believe will optimize with our development program. But if anything, and almost more importantly, it's allowing an accessible, relatively less expensive option. And we believe that our COGS will be critical in that, and the approach we have is critical.

So stay tuned. We're hoping to have more information for the investor community, the scientific community later in the year.

Paul Choi -- Goldman Sachs -- Analyst

Thank you. Our next question comes from Emanuela Branchetti of H.C. Wainwright. Your line is open.

Emanuela Branchetti -- H.C. Wainwright and Company -- Analyst

Good morning, everyone, and thank you for taking my question. So a question regarding the launch of both drugs in Europe. Perhaps could you provide more color on the status of their launch in Europe, particularly in the regions that were recently added? Also, is there any specific update or strategy for their launch in additional geographies?

Sheldon Koenig -- President and Chief Executive Officer

Sure. Yes. So happy to. So Europe is actually, as we mentioned in our prepared remarks, is doing very well.

The leading market there is Germany. That's the largest market. They've also launched in the U.K. They've launched in Belgium.

They've launched in Switzerland. And soon, I believe they will also be in Spain. As we've mentioned, the launch has been received very well. Now again, they have a different label than what we have.

They have a label that allows for patients who do not have to be on the maximum tolerated dose of the statin. And they've done a very good job in being able to get out there and gain awareness and use that message. The number of patients that are currently on, whether it be NILEMDO or NUSTENDI, actually exceeds the number of patients who are actually on PCSK9. And keep in mind, PCSK9s have been out in Europe for about seven years.

So we've been very happy with our performance. And we work very well together. We have weekly meetings with them, and it's a very good collaboration.

Emanuela Branchetti -- H.C. Wainwright and Company -- Analyst

Great. Thank you for that. And perhaps a question regarding the CLEAR ACS study. Could you give us a sense of what is the percentage of patients that currently achieve LDL-C goals post ACS event only with the current standard of care? And I guess how important is the quick LDL-C lowering post ACS event for the patient prognosis? I'm trying to understand what would be considered a positive outcome and how relevant is this study for physicians.

Thanks.

JoAnne Foody -- Chief Medical Officer

Yes. Emanuela, thank you so much. We're really excited about CLEAR ACS for many reasons. But one is that despite the existing therapies, we know that still, to this day, that post ACS patients at a year, 70% are not at their goal.

And we appreciate that in post-ACS patients, the LDL recommendation is less than 55. So you recognize that that's a very high bar to achieve with respect to LDL cholesterol. We believe that bempedoic acid, but particularly the combination with ezetimibe, NEXLIZET has a significant opportunity to achieve LDL goals in these patients. And that's exactly the study design of CLEAR ACS, right? Can we add our therapy to existing standard of care in this Northern California system to improve the proportion of individuals post ACS who achieved their LDL goals short term, but even long term? And it's a very pragmatic study, but I think will provide clinicians a tremendous amount of information in how to better achieve LDL goals in this very high-risk group of patients.

So hopefully, that helps.

Thank you. [Operator instructions] Our next question comes from Judah Frommer of Credit Suisse. Your line is open.

Judah Frommer -- Credit Suisse -- Analyst

Yeah. Hi. Thanks for taking the question. I was just hoping you could remind us of the patient support process you have in place right now as you've moved away from the Co-Pay Cards during the pandemic? What can patients expect with their first prescription? And how is the prior authorization support process for physicians' offices changed? And what is feedback as of now?

JoAnne Foody -- Chief Medical Officer

Sure, Judah. So what we had found with our offices is about 50% of the offices do prior authorizations exquisitely well, and they have their own support process in place. But there's about 50% of our offices that really do need assistance with prior authorization. We had put together the Next-Step Navigator program to assist with this endeavor.

And we have over 5,000 patients now enrolled in that program. We're seeing the refills from a persistency standpoint. And we have a host of other materials and tactics used in offices for a pull-through and really get patients on product and staying on products. So the prior authorizations continue.

But what we found is, with the right patient, the prior authorizations are labeled exact. And when physicians are writing for the right patient and they're documenting the -- for the prior authorizations, then those prescriptions do go through. So it's been in education, but pleased to say it's going much better. And also, the service we have, the Next-Step Navigator, it is the conduit with almost concierge services with the offices, the patients, and then also will go back and forth with the payer on behalf of the physician's office.

Judah Frommer -- Credit Suisse -- Analyst

OK. Thank you. 

Operator

Thank you. At this time, I'd like to turn the call back over to Sheldon Koenig for any closing remarks. Sir?

Sheldon Koenig -- President and Chief Executive Officer

Great. Thank you, Lateef. So I just want to, first of all, again, thank everybody and remind everyone that we are actively educating physicians about the benefits of bempedoic acid in different patient populations ahead of the CLEAR Outcomes study and the conference presentations that will come in the future. With over $268 million on the balance sheet, Esperion is well capitalized and positioned to execute on our strategy in these current market conditions and beyond.

And again, I want to thank everyone for their interest in Esperion. Have a great day.
