Ladies and gentlemen, thank you for standing by, and welcome to the Q2 2020 Pacira BioSciences Earnings Conference Call. [Operator Instructions] Please be advised that today's conference is being recorded. [Operator Instructions] I would now like to hand the conference over to your speaker for today, Susan Mesco, Head of Investor Relations.

Please go ahead..

Thank you, Demetrius, and good morning, everyone. Welcome to today's conference call to discuss our second quarter 2020 financial results. Joining me on today's call are David Stack, Chairman and Chief Executive Officer; and Charlie Reinhart, Chief Financial Officer.

Before we begin, let me remind you that today's call will include forward-looking statements based on concurrent expectations. Such statements represent our judgment as of today and may involve risks and uncertainties.

For information concerning risk factors that could affect the company, please refer to the company's filings with the SEC, which are available from the SEC or our website. With that, I will now turn the call over to Dave Stack..

First, the combination of iovera plus EXPAREL as a multimodal procedural solution for TKA procedures; and second, osteoarthritis patients seeking drug-free, opioid-free, surgery-free pain management that lasts several months. On the clinical front, we remain on track to begin enrollment this summer of our PREPARE study.

PREPARE will evaluate iovera and EXPAREL for opioid-sparing pain management for patients undergoing total knee arthroplasty. iovera will be administered before surgery, and EXPAREL will be administered during surgery. With iovera, patients can prepare for surgery with several months of non-opioid pain control.

We also expect that EXPAREL plus iovera for postsurgical pain control will support a more rapid functional recovery. There are 14 million individuals in the United States who have symptomatic knee osteoarthritis. And when we look at the market potential, we believe that this is a $1 billion opportunity, where iovera can capture a meaningful share.

As we continue to work with these key opinion leader surgeons and anesthesiologists, we have identified a number of additional cryoanalgesia treatments for development, such as low back pain, spine, spasticity and face pain, where there are thought leaders who have experience in developing treatments and a great interest in the opportunity to utilize iovera.

Turning now to our second growth pillar, pursuing innovative products or technologies. Strategic partnerships and acquisitions that align with our mission, such as iovera, remain a key component to our strategy as we leverage our established infrastructure and P&L.

We are thoughtfully pursuing opportunities complementary to our existing offerings and that are also of interest to the surgical and anesthesia audiences we are calling on today.

We see a significant opportunity to build a differentiated non-opioid portfolio focused on the patient journey along the neural pathway and have several robust opportunities to consider from a business development team. Sports medicine remains a key area of strategic focus.

Here, ASCs are the typical site of care, so this is a well-defined physician specialist group who are already engaged with – who we are already engaged with day-to-day.

The rapidly growing market is driven by a continuous influx of new products and increasing incidence of sports injuries and the significant advances in the field of gene therapy and regenerative medicine.

Sports medicine also offers a prospect of engaging younger patients earlier in their journey with pain and degenerative conditions, which is especially important with our projected launch of EXPAREL label for patients aged six and up next year.

Finally, let's discuss our third growth pillar, advancing a pipeline of non-opioid opportunities for acute and chronic pain. Our in-house team is focused on leveraging the proven safety, flexibility and customizability of our DepoFoam platform.

Last year, we announced two new DepoFoam programs that were released – or that were selected for clinical development. First, the intrathecal or subarachnoid delivery of DepoFoam-based local anesthetic for acute and chronic pain. Earlier this year, we met with the FDA to discuss this program, and a Phase I clinical study is now underway.

Next, we are currently optimizing formulations for depodexmedetomidine, and we will begin a pilot study shortly – or later this year in healthy volunteers using a simulated release. We look forward to keeping you apprised of our progress on both of these important programs. With that, I'd like to turn the call over to Charlie to review the financials.

Charlie?.

Thank you, Dave, and good morning, everyone. I'll start by summarizing our second quarter 2020 financial results. Before proceeding, I'd like to remind you that I will be discussing non-GAAP financial measures this morning, which we believe more accurately reflect our business results.

A description of these metrics, along with our reconciliation to GAAP, can be found in the press release we issued this morning. I'll begin by briefly echoing Dave in saying that the fundamentals of our business are very strong and the sales trends we are seeing are highly encouraging.

We are well equipped to successfully navigate these challenging times and overcome any temporary disruption to top line sales. We delivered year-over-year revenue growth of 25% in 2019, and these robust growth trends continued through mid-March.

We are now seeing a consistent uptake in EXPAREL sales and ordering accounts on a weekly basis since the peak of the COVID-19 pandemic impact in April, with both June and July returning to year-over-year growth.

We remain very bullish about the future of our business, which is on track for accelerating profitability now that many states are back to regularly performing elective and emerging procedures in hospital inpatient, hospital outpatient and ASC sites of care.

Furthermore, our organization has been preparing for a long time to capture the increasing number of procedures moving to the ASC setting, and COVID-19 has only accelerated this shift. We ended June in very strong financial position with $335 million of cash and investments.

In July, we completed a very successful offering of convertible senior notes due August 2025 that brings our pro forma cash balance to more than $500 million. Second quarter total revenue of $75.5 million was approximately 74% of total revenues for the second quarter of 2019.

This decline was, of course, due to the negative impact of COVID-19 and public health guidelines and government directives that postponed elective surgical procedures. Net product sales of EXPAREL were $73 million, which was approximately 74% of the second quarter of 2019.

For iovera, we reported net product sales of $1.4 million for the second quarter of 2020 as compared to $2 million for the second quarter of 2019. We kicked off the relaunch of iovera at our national meeting in February. However, the launch was interrupted in mid-March when TKAs in HOPD setting were postponed due to COVID-19.

During the second quarter, we shifted our focus to iovera utilization in physician offices to help our orthopedic customers offer non-opioid pain management to patients who have delayed TKA procedures due to COVID-19. Our non-GAAP gross margin for the second quarter of 2020 was 72% versus 77% for the second quarter of 2019.

Gross margin was negatively impacted by inventory write-offs as well as unanticipated downtime at our manufacturing site in Swindon. Non-GAAP research and development expense were $12.3 million in the second quarter of 2020 versus $16.6 million in 2019.

The decrease was primarily driven by the completion of our EXPAREL clinical studies in pediatrics and cesarean section as well as COVID-related study delays. These decreases were partially offset by the advancement of our Phase III lower extremity nerve block study and our Phase I pharmacokinetic study of EXPAREL via intrathecal injection.

In addition, second quarter R&D spend benefited from reduced costs related to manufacturing capacity expansion, with the transition of our 200-liter suite at our Swindon facility from development phase to the registration phase. Non-GAAP SG&A expenses were $36.8 million in the second quarter of 2020 versus $43.8 million in 2019.

This decrease is primarily attributable to reductions in J&J commission, which are directly linked to EXPAREL growth. In addition, the use of lower-cost virtual tools and the cancellation of in-person meetings, medical conferences and nonessential travel all triggered meaningful savings on the SG&A line.

All of this resulted in non-GAAP net income of $5 million in the second quarter of 2020 or $0.12 per diluted share versus $17.5 million or $0.41 per diluted share in 2019.

Looking ahead, we will continue to seek ways to reduce costs while remaining fully committed to providing the necessary investment for the growth of our products, future indications and pipeline.

Operating expenses are being managed very closely with the potential significant full year reductions in SG&A expenses given the social distancing implemented by state and local governments. We remain committed to profitability and expect to be adjusted EBITDA-positive for the full year.

Looking out over the long term, our 5-year plan remains unchanged with anticipated high-teen top line annual growth rate, steadily improving margins, appropriately managed operating expenses and significant adjusted EBITDA.

As Dave mentioned earlier, we are not reinstating 2020 financial guidance today given the continued uncertainties around COVID-19. But in order to provide greater transparency, we are reporting monthly revenue to share intra-quarter trends. We will consider changing this practice as we learn more about the impacts from COVID-19 as the year progresses.

To remind you, state and local mandates on elective procedures can have a meaningful impact, and seasonal factors are also difficult to predict with a high degree of accuracy. We are very confident in the continued growth of our business given the market's desire for opioid-sparing postsurgical pain management.

With that financial review, let me turn the call back to Dave for his closing remarks..

Thank you, Charlie, for that review. We have come through a difficult time, and the current market trends are indicating a positive turnaround. We will continue to monitor how COVID-19 unfolds and the impacts to the market.

We are ready and prepared to respond accordingly, noting that patient care and the safety of our employees will always be – remain the number one priority. As we move into the back half of 2020, we have several value-creating milestones we expect to achieve.

We look forward to securing regulatory approval of EXPAREL in both Europe and Canada, expanding our U.S. label to include pediatrics, reporting top line results from our lower extremity nerve block study and taking full ownership of the EXPAREL franchise as we wind down our partnership with DePuy Synthes.

Importantly, we have the financial foundation from which to achieve our goals, and we are moving quickly with strong and – top line and bottom line growth. As we look ahead beyond COVID-19 procedure disruptions, we are extremely optimistic about our growth prospects in the long term.

As you'll recall, EXPAREL grew by more than 23% in 2019, and that demand continued unabated in January and February 2020.

Given this momentum, along with new C-section data publications, pediatric and lower extremity nerve block label expansions and the rest of world launches, each of which represents an additional addressable market opportunity of $100 million per year, we are highly confident in our five-year planning growth projections.

We are well equipped to quickly transition into a powerful earnings story with top line year-over-year growth in the high teens, steadily improving margins from the mid-70s to the mid-80s and appropriately managed operating expenses.

Before closing, let me take this opportunity to thank our shareholders, along with our dedicated employees, for continued support and encouragement as we build Pacira into the world's leading provider of non-opioid pain management and regenerative health solutions. With that, I'll turn the call over to the operator to begin Q&A sessions.

Operator?.

Thank you [Operator Instructions] And our first question comes from David Amsellem with Piper Sandler. You may proceed.

This is Zach on for David. So just starting off with COVID.

I guess given the case burden that is obviously growing across the country right now, I was just wondering if you could speak a little bit more, provide a little bit more color on what you're expecting now in terms of pace of recovery for EXPAREL in later half of this year and 2021 and that – and what that might mean for sort of further catalyzing migration in the ASC setting going forward..

Sure. Thank you for the question. What we see here over the last several weeks is we are highly sensitive to the increase in COVID-19 cases in the primary ambulatory surgery states like Florida, Texas and California. And so we've seen those states stabilize basically on a week-to-week basis.

At the same time, we've seen the states who are less reliant on ASCs, or who were slow to recover, come online so that we've continued to see a weekly increase in sales. And so I think what we're seeing is that the ASC is becoming the primary route of recovery. And so as the – as all 50 states participate in a higher level.

And then when we see these states, the leading states like Texas, California and Florida, and we see these spikes abate, we expect that we're in a very good position to continue to come out of this in a very strong way.

I mean I think the nature of your question is, how does the ASC lead us through the rest of the year? And other than the governmental control of elective procedures, and if we don't have any unforeseen spikes that lead us to state governments shutting down elective procedures in the hospital outpatient and the ASC, I think we're in very good shape to meet the number that we've been talking about for many months now, that we would see roughly 80% to 85% of the procedures come back and be performed and that the majority of those would be recovered in the ambulatory – in the 23-hour stay market..

Okay, great. Thank you..

Thanks..

And our next question comes from Randall Stanicky with RBC Capital Markets. You may proceed..

Two questions. Number one, can you help us understand how sticky the business is on the ortho side as we think about J&J stepping away as your partner in 2021? And specifically, how much new spend that you're going to need to support that business. This has been a recurring investor question. And then secondly, I just wanted to ask you about July.

How normal was that month? Because if you annualize the $38 million in EXPAREL sales, you get close to where your initial guidance was for the year. So I'm just trying to understand how much more opportunity is there. Was there any kind of catch-up in that number? Just how to think about that month from a sales perspective..

Thanks, Randall, and the – both very relevant questions. So when you look at the projected savings from the termination of the DePuy Synthes relationship and we look at the additional cost that will be borne by our taking the place of those services, it's roughly 10% of what will be saved.

So just to be complete here, we've been adding folks for iovera. We've got a field force alignment and allocation model that has already anticipated that we were going to be replacing DePuy Synthes at the end of 2021. So we've moved that forward modestly.

And along with the build-out of our training center in Tampa, which will allow us to do a lot of these things virtually in this post-COVID world that we're addressing, we think that the investment will be modest relative to the savings. And as I said, roughly 10% of what we're expecting to save will be allocated to that effort.

July is an interesting month, and I appreciate the question because we think about it the same way you are. So that's why I mentioned in my previous answer that what we saw was the market is stable to growing modestly, and I'm sure that's the nature of your question.

We think that that's very encouraging given that we didn't see the same kind of progression of growth in the big states that brought us out of this recovery. So specifically, Florida, for example, was significantly ahead of pre-COVID going into July and has come back to basically flat on pre-COVID now.

So what we see here is that as we get over these spikes in these big states for ASCs and where there's a lot of business in a traditional sense anyway, we think that we're in a great spot to benefit both from the growth in the states that were delayed or don't have the same reliance on ASCs, who are finding different ways to treat these patients in the 23-hour stay environment, hospital outpatient, for example.

And so as the big states come back online, we think we're very well positioned to continue to grow through the back half of 2019, always, of course, stating the obvious that the unknown of additional COVID spikes, especially in these heavy ASC states, or any government mandates that come down could have a significant impact on that.

But ex those kinds of intrusions into the marketplace, we think we're in a really good position here..

Great, thanks guys..

Thanks, Randall..

And our next question comes from Greg Fraser with Truist Securities. You may proceed..

Good morning guys. Thanks for taking the questions..

Good morning Greg..

I was wondering if you could discuss your strategy to build patent protection around EXPAREL. And specifically, maybe you can comment on the types of patents that you're pursuing and when you think patents could issue..

That's a long – that's a three-credit course, Greg. I'll go quickly. First of all, we – and as we've said several times, the points to consider that were developed by the generic division of the FDA, we think, help us a lot.

Because of their demand that you would have an exact duplicate of EXPAREL, someone would have to have the specifications for release that we use in order to release a batch of EXPAREL from a manufacturing facility. And then they would have to validate that by being able to have an assay that measures all of those specifications.

And so we see – the fact that we've never disclosed those specifications into the marketplace is a significant hurdle.

And the fact that the assay that measures those release specifications is – was developed by Pacira, is proprietary to Pacira, and we've never told anybody what that assay is, is the second significant hurdle in addition to sterile manufacturing and all the rest.

So in addition to that, we've got a series of patents that were filed with the PTO many years ago on spray technology. And so we have not disclosed in a general sense which of these technologies are being used by our manufacturing facilities and when we will use any of the above-mentioned patents.

When we were – and so that's sort of part four, if you will. And then as we've built out the 200-liter facilities, we have come up with a number of nonobvious, unanticipated observations that have been patented. So we – the PTO could come back with the patents on the new manufacturing process.

I mean they've been filed for many years so that could be any time in the relative short term. The new patents based on observations in building out the 200-liter, Greg, would take several years to come through the PTO.

In the interim, we don't believe that anybody has got any type of commercial manufacturing that would allow them to manufacture a multivesicular liposome of any kind, specifically EXPAREL. So it's not a perfect answer to your question.

We filed a number of patents and continue to file a number of patents, not only around these observations but also on different IVRA, as we call it, this assay that allows you to release these different batches. And so we think we're in a strong position relative to anybody being able to make a generic EXPAREL in a bit of a nontraditional way.

But we don't see a generic patent coming in the foreseeable future, if at all..

Great, thanks for all the color..

Thanks Greg..

And our question comes from Ami Fadia with SVB Leerink. You may proceed..

Thanks for questions.

So on the pace of recovery across the states – different states, could you give us some idea about the variation from state-to-state? What are the best and worst states currently doing in terms of surgery volume and EXPAREL use? Is the 109% year-over-year growth in July you've seen driven by a few large states? Or is it robust recovery across the board? So for example, you mentioned that some large states are heavy with ASCs like Florida, Texas, California.

But these states are also – have seen a great spike in COVID cases these days. So have you seen these states taking any measures of rolling back their elective surgery? For example, Texas, probably – I thought Texas put a pause on elective surgery a few weeks ago. So any color on those measures will be appreciated. Thanks.

Sure. No. Thanks for the question. Let me go in reverse. So first one, there have been no rollbacks of elective surgeries in ambulatory surgery centers and hospital outpatient departments that we're aware of. You are correct.

There were situations where hospitals were saved for the potential [indiscernible] and so elective surgeries were not allowed in hospitals, but they have never been diminished in – or eliminated from ASCs and HOPD use. So that's a very important aspect of answering the question that you just asked.

So what we saw in July was that we saw a still growth in Texas, in California specifically, over 2019. Florida moderated back to where it was basically pre-COVID. And making up the difference from the previous months were a number of smaller states who are not as dependent on HO – or on ambulatory surgery centers.

We did see New York state, for example, come back strong in the July time period. In states like Ohio, North Carolina, Georgia, those kinds – those states are also participating in a more meaningful way than earlier in the COVID recovery. So to be very specific, Texas, California, Florida largely led us out of this mid-April time period.

With the increase in COVID-positive cases in those states in the July time period, the governors did not close the opportunity for surgery. But what we saw was the number of patients who were infected and their extended families really dampened the number of patients who are appropriate for an elective surgery in any case.

And so we think that was the reason for some moderation in the growth in those states. So we were able to maintain our growth, especially since July of 2019, with participation from a bigger – a larger number of states.

And that's what gives us the confidence that when we do have a return to normal in the big ASC states, like Texas, California and Florida, that – with the participation of all of the other states, we believe that we're going to be in a position to get back to that pre-COVID growth rate that we talked about during the script..

Thanks, that’s helpful..

Thanks for your question..

And our next question comes from Serge Belanger with Needham & Company. You may proceed..

Hi, good morning. A couple of questions for me.

First, Dave, on the marketing footprint of the company, can you tell us what that looks like once the DPS collaboration is over? And should we expect any additions to that footprint with a label expansion to pediatrics and lower extremities?.

Yes, thanks for the question, Serge. So we have separate customer-facing organizations. And so we started earlier this year, actually, expanding the regular sales force, our normal-sized sales force, that is driven by surgeries and surgical procedure opportunity on a geographic basis. And there's roughly 140 folks in that organization, Serge.

And we started adding to that and training on that so that we would have been at full allocation at the end of 2020.

Now given COVID and some of the new ways that physicians want to deal with us on a virtual basis or the inability to make time to train and to see our representatives because they're so busy in the operating room, we've got a dozen or so territories that are open that we are not going to fill until the end of this year when we have a better grasp on exactly how we're going to interact with our customers and how we're going to train those folks.

At the same time, we've got an organization of roughly 50 that do nothing but train. And so there's an innovation team and then there's a clinical education team, and these folks train all of our anesthesiologists and all of our surgical customers.

We've increased the size of that sales force to anticipate the fact that we were going to be doing more virtual sessions and more training sessions that were not going to be live, that we're going to be doing in a more virtual, online way. And that's already taken place. And so there's a few more places that we will add based on the iovera rollout.

But I think, generally speaking, that is rightsized as we move away from DePuy Synthes. We've hired a team of specialty nurses who will work in the pediatric hospitals.

There's only roughly 60 of those in the United States that are of significant strategic interest so we don't believe we need to increase the size of the sales force at the current time in order to address the pediatric opportunity.

And right now, we're looking at having data from the STRIDE study on lower extremity nerve block at the end of Q1 in 2021. And so with a normal 10-month review process, we would get approval for the lower extremity nerve block early in 2022 and so there's no plans to address that opportunity today.

That will be something that we do sort of mid-2021 so that those people are trained and available for a national meeting in early 2022 as we launch nerve block so – our lower extremity nerve block. So we're watching the marketplace. We're building out the training center in Tampa, where we think that we can train physicians 100 at a time.

We also have strategic relationships with MEDNAX and Envision and a number of other anesthesia groups. So we're training more and more people on regional anesthesia, and that's being done by our clinical education team and by our innovation team. So we think we're in a very good spot.

And that's why the amount of resource – additional resource that needs to be added here to be able to service our customers when we do not have any longer relationship with DePuy Synthes is relatively modest relative to what we have today..

Okay. My second question is regarding the reimbursement environment for EXPAREL.

As usage increases outside the hospital and especially in ASCs, any expected changes to CMS policies or payment levels that we should look for in this fall?.

No. As a matter of fact, two days ago now, CMS came out with their 2021 OPPS guidelines. And they make specific mention that the only ASC product that is unbundled from the surgical bundle is EXPAREL. We also have seen that CMS will pay for total hip arthroplasty as we move into 2021. So CMS, we're in very good shape.

We also continue to work with commercial payers. And Aetna, for example, is paying for hospital outpatient use of EXPAREL in the state of Florida. So we see that as a good pilot for us as we improve reimbursement with our commercial payers as well.

And there's a number of concierge-type services, Serge, that have – that are entering the marketplace now, where they work directly with self-insured providers, payers. And so we've got very significant relationships with those folks as well.

And I should also mention that CMS has increased the payment for EXPAREL to $1.29 a milligram now, and so there is no reason to expect that there's going to be anything negative happening with the reimbursement of EXPAREL.

And increasingly, we see payers of all sorts more interested in moving patients out of the hospital environment, and the way to do that is with EXPAREL.

And so if an insurer is thinking that they're going to save several thousand dollars on a major procedure like a spine or a knee, it is not an issue at all to spend $300 to make that happen by using EXPAREL..

Thank you..

Thank you for the question..

And our next question comes from Gary Nachman with BMO Capital Markets. You may proceed..

It's Rafay on for Gary.

Could you comment on your current appetite for business development? Are you looking at opportunities more aggressively following your recent debt refinancing that strengthened your cash position?.

Not more aggressively, Rafay. We never – Ron Ellis and his team never really stopped looking at these – at the opportunities that we're interested in. So we continue to work with a number of different opportunities.

There's a couple that we're really excited about that we continue to pursue, and we expect to be able to tell the world about a couple of these things before the end of this year. So no, we've been very active. There's a number of things that are of great interest to us.

And always, the additional cash always helps, of course, but I wouldn't say that we're any more aggressive now than we were before..

Thanks.

And then for the pediatric indication, how quickly do you expect EXPAREL use could ramp in that patient population? And are you still targeting a nerve block indication for pediatrics?.

So two different things, right? So the pediatric community is relatively small and so we will have to train, of course, which is one of the reasons for the Tampa training facility.

But we expect it with a relatively modest requirement for hands – rep-to-customer training, that we will be able to train this community very quickly and that this will ramp much more quickly than any of the other indications that we've ever had an opportunity to put into the marketplace. And we see great interest.

When we're talking to these folks, in addition to EXPAREL about iovera, there's a lot of interest in the pediatric marketplace and frankly, some anger, actually, in some cases, when the anesthesiologists and when the pain management folks and peds find out that no local anesthetic is currently approved for pain management in a pediatric patient.

Most were not even aware of that. So there's a lot of positive energy in that marketplace. So this first indication, as you point out, is for infiltration. We are working with the FDA on a nerve block indication. It is not easy to find a nerve block indication that would be – that would pick up on the adult use of the product.

Where you find yourself going are things like open fractures and things like that. And we know from experience that emergent situations – emergency situations where mom and dad have to sign a patient into a clinical trial are very difficult. The FDA knows that.

And so we're working with them on finding an appropriate procedure, where we can do a study that would add to the EXPAREL label for nerve block in kids..

Thank you..

Thanks..

And our next question comes from Dana Flanders with Guggenheim. You may proceed..

Thank you. So from the questions, Dave, I know you just mentioned you have a study reading out in lower nerve blocks in Q1. Can you just remind us how you are viewing that opportunity and the importance of that indication for future EXPAREL growth? And I know pain studies are tough, especially it's an active comparator.

What have you learned or incorporated from prior nerve block studies to position this one for success? –––––––––––––––––––––––––––––––––––––––– David M. Stack, Pacira BioSciences, Inc. - Chairman & CEO [25] –––––––––––––––––––––––––––––––––––––––– A lot. Well, thanks for the question, Dana.

Obviously, we're not going to teach – we've done enough teaching of other competitors – potential competitors on how to do clinical trials in pain. So there's a number of not obvious things that we – that we're able to do in these clinical trials that allow us to have the clinical success that we've had.

I don't think that there's any reason to believe that lower extremity nerve block will be any different than that. I think the first thing that is obvious, at least to us, is that you can't use the competitive agents in any kind of appropriate way in a nerve block indication largely because they're neurotoxic for one reason or another.

But secondly, they have limitations on how those products can be used. When we're doing either a nerve block or a field block, EXPAREL allows us to put the drug in direct contact with the sensory nerves and then set itself up in such a way that these multivesicular liposomes release small quantities of bupivacaine over the next three to four days.

But they're in such close proximity to the sensory nerves that we can achieve this long-term application and long-term extension of pain control. And as far as we know, at least today, Dana, the only product that allows you – the only delivery technology that allows you to do that is DepoFoam.

So in some respects, it's easier for us to do, but we also know that there is a number of problems when you're working in an area where you cannot let the patients have pain. So you have to provide a rescue. It's not so much whether you rescue or not.

It's more the statistical analysis that you apply against that and how you analyze the impact of rescue medications, which rescue medications you allow, how you set up your protocol in order to capture that in such a way that not only allows you to deal directly with the regulators in a meaningful way, but also allows you to deal with your practicing surgeons and anesthesiologists so that you can be very forthright with them about the impact of trying to control the subjective nature of pain, especially when the clinical trial has so many different variables that you have to measure.

It's really all about how you set up the stats protocol and how you set up your protocol and your relationship with your clinicians so that they're able to follow a fairly complex protocol. And you're exactly right, that 50% of pain trials fail for a lot of reasons that we've been able to identify in the 10 years that we've been developing EXPAREL.

So not in a position to give any of the specifics, but I think we're in a very good spot to be able to achieve a nerve block claim. And the FDA is very interested in this. We've been working with them on a regular basis with the STRIDE study.

And one of the reasons that we've moved this back a couple of months is because we've been working with them on a couple of modifications that they suggested that they think will make this a much easier trial to evaluate on the backside after the patient enrollment is complete.

Anything else, Dana?.

And just can you remind us how you're viewing the opportunity – the market opportunity? Thanks..

So the fastest-growing use of nerve blocks and field blocks is in foot and ankle. So we think that that's a specific number that leads us to be quite hopeful about the future of nerve block in this indication. We also know that there's a significant use of EXPAREL currently in adductor canal blocks in the knee.

And so we think that we would have a much higher market share if we had a nerve block indication for the lower extremity.

So in the upper extremity – and remind you that the brachial plexus nerve block launched in April of 2018 was when the company really accelerated again and where we got into the low teens of EXPAREL growth on a quarter-by-quarter basis. We think that the same kind of opportunity, the same magnitude opportunity is available for the lower extremity.

And we also like this because many of these surgeries are actually done on the ambulatory surgery center already.

So being able to replace pumps and catheters and a lot of the ways that docs – a lot of the techniques that docs are currently using to achieve several days of pain control, we think, can be much improved with a single dose of EXPAREL that gives you several days of pain control.

So we think this is another rapid, customer-demanded opportunity to move a patient to an ambulatory surgery center and provide pain control at the same time..
