Ladies and gentlemen, thank you for standing by. Welcome to the Axonics fourth quarter 2019 results conference call. At this time, all participant lines are in a listen only mode. After the speaker's presentation, there will be a question- and- answer session. To ask a question during the session, you will need to press star then one on your telephone. If you require any further assistance, please press star then zero. I would now like to hand the conference over to your speaker today, Neil Bhalodkar. Please go ahead.
Thank you, operator. Thanks everyone for joining the Axonics quarterly results and update call. I'm thrilled to have recently joined Axonics as Vice President of Investor Relations. Presenting on the call this afternoon are Raymond Cohen, Chief Executive Officer, and Dan Dearen, President and Chief Financial Officer. Ray and Dan will provide prepared remarks and commentary on the fourth quarter financial results, U.S. commercial progress, and a general business update, followed by a Q&A session.

Thanks, Neil, and welcome to Axonics. We're looking forward to your contributions in what we expect is going to be a busy year. I'd like to thank everyone who's dialing in for today's call and for those of you who may listen to the webcast. Since our last call in 2019, a lot has changed for Axonics as we have transitioned to a full-blown commercial company with significant operations in the United States. Case in point, in Irvine, California, we now have over 70,000 square feet of manufacturing and facility space, along with our 11,000 square foot training center. Our employee headcount is now over 142 persons. The U.S. field sales team consists of 11 sales managers, and 100 salespeople.
Since January, we have doubled the size of our field clinical specialist force that, as of the end of March, will number 68 individuals. That's a team of nearly 180 dedicated professionals calling on physicians and institutions and covering cases in the U.S. We just returned from our first post-FDA approval commercial exhibition at a major medical congress. This was the Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction. It was in Scottsdale, Arizona, attended by over 650 physicians. Dr. Kevin Benson, a KOL working at Sanford Health in Sioux Falls, South Dakota, and one of the ARTISAN-SNM pivotal study investigators, presented our one-year clinical results demonstrating 89% efficacy. At this conference and other conferences, these results are now being referred to as the best ever to be reported in this particular category.
The results of our initial U.S. launch in the fourth quarter of 2019 have even exceeded our own optimistic expectations, resulting in $8.4 million in sales with physicians in over 200 hospitals and ambulatory surgery centers having implanted patients with our Sacral Neuromodulation System in November and December alone. There was no stocking during this particular quarter. In fact, just to add some color, most hospitals these days are reluctant to stock product in any case. Our momentum has continued into the first quarter. We have an additional 100+ centers that are now implanting our product. To date, we have approximately 30% of the top 1,000 centers that practice sacral neuromodulation implanting our product. This includes national and regional IDNs, large urology groups, and ambulatory surgery centers.
I'm going to provide some more information and a little more color on today's call. First, similar to our past quarterly calls, Dan Dearen, our President and CFO, will start by reviewing our Q4 and fiscal 2019 results. Dan?
Thank you, Ray. For the fourth quarter of 2019, we reported net revenue of $9.9 million. This compares to $494,000 in the fourth quarter of 2018. Net revenue for the fourth quarter of 2019 was derived primarily from the sale of our r-SNM systems to customers in the U.S., England, the Netherlands, Germany, Switzerland, and Canada. The gross profit for the fourth quarter of 2019 was $5.4 million, representing a gross margin of 54.4%. We are pleased with the gross margin we have seen out of the gate and at this level of sales. As processes to ramp manufacturing are implemented, we anticipate gross margin expansion commensurate with volume and scale.
Since it's likely to be a question, I would like to note that Axonics does not manufacture any of its products in China. All of our products are made in the United States, either in our Irvine facility or at contractors based in the U.S. Therefore, we have minimal exposure in manufacturing to the coronavirus situation. Total operating expenses for the fourth quarter of 2019 were $28.1 million, which is an increase of $18.4 million compared to the same period in 2018. The increase was primarily due to higher personnel costs for the U.S. commercial team and across the organization related to increased headcount to support the commercial launch of the company's r-SNM system in the United States.
Given the strong traction we are seeing to the rollout of our system, we will continue to hire clinical specialists and support personnel as needed to ensure physicians and their patients continue to receive best-in-class service and clinical support from the Axonics team. We will also be adding manufacturing personnel to increase capacity and keep up with demand that has exceeded initial launch expectations. Operating losses for the fourth quarter of 2019 were $22.7 million as compared to operating losses of $9.5 million in the fourth quarter of 2018, driven by the same factors discussed above. Cash, cash equivalents, and short-term investments on the balance sheet were approximately $183.7 million as of December 31, 2019. I'll now turn the call back over to Ray.
Thanks, Dan. Commercial feedback from physicians and patients based on well over 1,000 commercial implants has confirmed that our thesis that we have delivered a device that is preferred by both physicians and patients, and that our field team can compete on a first-class basis, whether it be supporting cases in the OR or programming our device. We feel really good about the initial feedback that we have gotten to date. As I've mentioned numerous times over the past year, we expect to not only compete, but over time, to become the dominant player in sacral neuromodulation. Moreover, we fully expect more patients to choose sacral neuromodulation as the preferred third-line therapy to treat urinary and fecal dysfunction, given the characteristics of a long-lived MRI-compatible system that is fundamentally fuss-free.
We also expect the U.S. market for sacral neuromodulation to grow substantially over the next few years as sacral neuromodulation becomes less of a secret and more patients are saying yes to the therapy. This is the number one way that this market is going to grow. We believe that the clinical data and our ease-of-use product is of critical importance to the customer base made up of urologists, urogynecologists, and a smaller group of GYNs and some colorectal surgeons that actually implant sacral neuromodulation devices. Our fourth-quarter seminar series suggested this, and this is proving out actually in the field. Anecdotally, physicians report that patients are having better symptom relief than they have seen in the past. Additionally, in just 120 days, we are seeing this trend come to fruition, reinforcing our bullishness about the long-term prospects for this market.
As mentioned earlier in the call, our momentum has continued into the first quarter of 2020, with now over 300 centers located all over the U.S. now actually implanting our product. This represents about 30% of the top 1,000 centers that actually practice sacral neuromodulation, accounting for approximately 80% of all the implants that are done in America. This group includes some of the largest national IDNs as well as regional IDNs, large urology group practices, as well as ambulatory surgery centers. We have a significant number of additional facility agreements that are actually in process, and we expect to have substantially all of our targets under contract by the end of Q2 2020. Our strategy of having our local reps execute these value-added committee or VAC meetings and pricing our system at parity have proven to be successful in getting these agreements in place quickly.
In addition, our new website, our public relations and social media campaigns are helping to bring more attention to the millions of women who are suffering in silence with these conditions. As I've stated many times, to date, sacral neuromodulation has been a secret therapy, and the vast majority of Americans have no idea that there's such a thing as an implant that can dramatically improve the quality of their lives. Our goal is to bring attention to this problem and to grow the market with the view that the expansion of this market will accrue to the benefit of patients, providers, as well as Axonics. All that said, Axonics is highly motivated. We're fully prepared to support our new customers. We're not resting on our laurels, and we'll continue to be the leading innovator in this field.
We have proven that we know how to work with the FDA, as evidenced not only by our PMA approval for all clinical indications, but also the recent PMA approval of our enhanced programmer. We continue to make regular supplemental filings with the FDA to gain approval for additional product enhancements, including expanding full-body MRI capability to include 3T Tesla scanners. Just to wrap up this section of the discussion, I'd like to say that we're making excellent progress in the first 120 days of our U.S. launch and our other strategic initiatives. We're confident about the future prospects for Axonics, and we are working diligently every day to fulfill our vision. At this point, we'd be happy to answer any questions that the folks on the phone would have, and we'll turn it to the operator now to announce the first person who has some questions.
Thank you. As a reminder, to ask a question, you will need to press star, then one on your telephone. To withdraw your question, please press the pound key. Our first question comes from the line of David Lewis with Morgan Stanley. Your line is now open.
Good afternoon, thanks for taking the questions. Just a few from me. First, just maybe focus on guidance. I know you've been very clear you were not going to provide guidance, but can you just sort of tell us broadly, are you currently comfortable with consensus numbers for 2020? More specifically, actually for the first quarter, where there's a lot of variability, street consensus is sort of $14.5 million-$15 million. Are you roughly comfortable with those first quarter and 2020 outlook as they stand today? A couple of quick follow-ups.
Sure. The short answer is absolutely yes.
On both, right?
Yes, sir. Absolutely yes.
Okay.
Yes. Yes.
That's very clear. Two more things. I know it's early, but can you give us any sense of growth as it relates to kind of new account penetration versus reorder sales? Any broader comments you can make on reorders is number one. I'll just ask my second question now. Your analysis suggests in the fourth quarter there was some modest market expansion, maybe 4% became 6%, 7%. Can you just talk to us about on an account level, you're obviously seeing evidence of share capture, but can you comment at all about the level of share capture or if you're seeing any significant practice expansion? Those two points would be great, reorder and the second question. Thanks so much.
Thanks, David. I appreciate the question. I'm going to take them in reverse, actually. I think that the reality is that we are seeing the market grow, and it's happening in a very simple way. The physicians are telling us that more patients are saying yes to the therapy. They're presenting the therapy, the characteristics of the long-lived implant, the fact that nobody has to worry about getting anything explanted for an MRI. Before people actually understand that we have an easy-to-use product or our patient remote is easy, those are the things that patients are going to talk about later. They're going to reinforce with their physicians and the nurses in the practice later. Initially, what the conversation between the physician and the patient is, I think sacral neuromodulation would be very helpful. This could significantly reduce your symptoms. Let me show you what we have.
Let's talk about this new product that's available. This is a device that could easily last 15, 20, maybe more years in your body. You don't have to worry about MRIs or anything else you might have heard. The fact is that they're telling us that this is a better and more attractive proposition for the patients, and their bottom line is patients are saying yes more often. This is anecdotal. It's difficult to measure. The physicians themselves are experiencing this in real time as it's happening. We're getting that feedback. They're almost surprised, right? They're happy to share this data with us or to tell us about this. We're seeing it's happening on a count-by-count basis, kind of one-on-one with patients. When we talk about this notion of share capture, it's not a static market.
It's not like there's so many devices that are going to be placed in hospitals, and they have this kind of budget and so forth. This is very dynamic. The reality is tomorrow, there are zero deals for sacral neuromodulation in America. Zero. There is no business, right? The business occurs conversation by conversation, physician to their patients. This is a very interesting and very dynamic market, and it's not static. With full reimbursement for Medicare and all private insurance companies, there's no barriers in the way to getting more patients access to this therapy. Okay. We hope to be able to have more data and be able to try to measure this in a more meaningful way as we go forward.
In terms of reorders, what I would tell you is every single account that we have opened, every single account we have reopened in the United States has reordered product from us multiple times. There is no question that they're finding the product easy to implant and the feedback coming from their staff and their patients is very positive. We just have not had anybody who has ordered once from us or did one implant and then decided that it's not working out or we're not providing the support that they would have expected. Okay. That's a non-issue for us. Every single day, I mean, literally every single day now, we have new customers that are coming to Axonics for the first time. This is happening on a daily basis, and this is why we now have over 300 centers that are implanting our product.
We do not expect this to stop. We're out in the field. We got a big force out there. We're calling on everybody that's doing any kind of volume. I just want to reinforce, and I'll stop talking in one second, but we're only calling on physicians that have experience implanting sacral neuromodulation. We're not going out to other physicians trying to bring them to the therapy. We may do that in 2021, but that is not our objective today. It's not to say that some physicians are not coming back to the therapy who may have abandoned the therapy for Botox, as an example, for a number of reasons that we won't necessarily dive into today. The top one is, I thought that the product that was available up until now was fussy. It was more trouble than it was worth.
I only presented it to the patients that had no other alternative, or I didn't like the wrap, or any one of a number of other things that they may have done. Anyway, that's the story. David, I just tell you, if you get the sense that I'm quite enthusiastic about what's happening for Axonics, then that's the right reading.
Well, I got that sense, Ray. Thank you, and I'll jump back in queue.
Thank you.
Thank you. Our next question comes from the line of Bob Hopkins with Bank of America. Your line is now open.
Oh, great. Thank you. Just a couple quick questions. The 300 centers that you're in, what percentage of the U.S. market do you think that represents right now?
We've always said, Bob, the way we've looked at the market is we identified that there were about 1,000 accounts that were doing approximately 80% of all the implants. We look at it through that filter. There may be literally hundreds of other physicians that are dabbling in the therapy. Those are not people that we're focused on at the moment. We think it represents, in effect, about 30% of the people that really matter in the United States.
Okay. I'm just curious, this is a high-class problem kind of question, but given the current trajectory of the company and the growth that you're experiencing, do you have enough inventory on hand to meet where the business is going in 2020? Do you need to scale up there? Is that a limiting factor, in other words?
Well, I could tell you if 60% of all the customers in America only want to buy from Axonics, yeah, we'd have some trouble meeting that level of demand. The only realistic answer I can give you is that we're working very diligently to increase our capacity. This is the reason why we've expanded our facilities and added another 35,000 square feet of manufacturing facilities. We haven't necessarily reported our headcount every single call, but we've added probably 75 or 80 people in the last three months alone. We are doing everything we can to scale up manufacturing without compromising quality, which is obviously the number one most important thing. We're planning for success. We're being successful. We're planning for more success, we're going to do everything that we can to meet demand.
At some point, if it continues at this rate, there will be a limiting factor.
Is there a sense for like, if you hit your scale-up plans for this year, what's the maximum revenue you could do? I'm just trying to get a sense of what that level is, where it would become limiting.
I can't really answer that question right now because we have a plan, and our plan that we made was to overachieve the consensus. Right? We've planned to overachieve that. It's kind of a fluid situation, so it's difficult to answer that question. I'm trying not to be coy about it. It's just that we're going to build as much as we possibly can and get that out into the field. There are some limitations in terms of how quickly we can scale up. If the consensus is, I think David suggested it was more than 14, let's just say it's $14 million. Obviously, we didn't plan to only build $14 million with the product, right? We're planning for success. We're planning to overachieve. Once again, there is a limit to that.
Lastly, just real quickly on Medtronic. Anything they're doing in the field that's surprising you at this point?
I would say there's really no surprises at all. Nothing really is new. Nothing has changed. We're just out there, heads down, doing everything we can to acquire these new accounts, to provide the level of support and service that we need to provide the marketing tools, and to do the other things that people are looking for. I think that the physician community is really kind of appreciating that Axonics has taken really a fresh look at this market, and that we've been extremely responsive to things that they've been asking for a long time, and providing the tools in the practice that are necessary, I shouldn't say necessary, the tools in the practice that are desirable to be able to have patients have a better understanding of what the therapy is and so forth.
This is basic blocking and tackling, but heretofore, there's never been a social media campaign about sacral neuromodulation. Nobody ever brought patient ambassadors to a medical trade show before, but we have. We're doing a lot of things like that. I think that we're moving really fast, and we're competing against a company that, let's face it, they've had this market all to themselves for 20 years. I think if anything, they may be a little bit surprised by the velocity in which things are happening in the marketplace.
Thanks very much.
Thank you.
You're welcome, Bob.
Our next question comes from the line of Kristen Stewart with Barclays. Your line is now open.
Hi, guys. Thanks for taking my question. I was just wondering if you could comment on what you're seeing in the individual accounts, just in terms of the uptake of your product as a percentage of implants, because I know there was a little bit of question just in terms of what the percentage of non-rechargeable implants would be for a physician's practice. I'm just curious if you have a good sense of what that number is on a general account basis. I have a couple follow-ups as well.
Thanks, Kristen. That's kind of a difficult question for us to answer because, once again, it's not a static situation, right? This is fluid, right? Patients are coming in every day, and they're talking or not talking about sacral neuromodulation. Here's what they're telling us, maybe this is the best way to answer the question. That when they're offering sacral neuromodulation to their patients, and if they're one of the group that is actually offering both product, and I would say, by the way, that's a minority, then patients are choosing our product in a significantly higher percentage than they are the short-lived, non-rechargeable device. Okay? That's what we're hearing. That's what they're telling us. Our sense is that when we're in a practice and we've gotten things going and 30 days or 60 days has passed, right?
Because in the first 30 or 60 days, they may have some patients they already trialed with the competitor's product. If they've done that, they may want to continue to go down that path, not to confuse the patient. As time goes on, there's no question that we get the lion's share of the implants in that practice. Some practices have just fundamentally switched wholesale to Axonics. They have no interest in working with the older product. Especially when they get reinforcement from their patients and their staff that things are going really well and that they are doing well clinically and that the staff is saying, "Look, this is really easy to use. We don't have the reprogramming that we used to have prior," and things like that. It's an interesting phenomenon that when you speak to physicians, you may get one impression.
When you speak to their staff, that's really when you learn about how well our product stacks up.
I guess, what's been the experience too, just as you're going out, trying to open accounts? To what extent has not having a non-rechargeable device been a roadblock? Where do you stand just on your next generation products with a non-rechargeable version? Where do you stand with getting the 3T labeling and then also the compatibility with existing leads as well? Any particular color that you can share from a European perspective on the competitive front with Medtronic, with their newer product too. That's all the 80 questions from me. Thanks.
I was going to say that's way too many questions for me to try to remember, but Dan's made a few notes here, so we'll do our best, okay?
Thanks.
Okay, I'm going to work backwards. Dan, if you got the notes, I'll work backwards. Number one, 3T, right? We had a Pre-Submission meeting with the FDA recently, to talk about expanding the labeling to include a 3 Tesla device or scanner. We expect to be filing shortly with the agency, who reviewed our technical data and encouraged us. We would expect that towards the latter half of this year, right, that that'll come on board. I want to remind people that in the United States of America, less than 15% of all the MRI scanners are 3T, okay? We live in a 1.5T world, and in some cases, less than 1.5. This is a really, in a way, and I don't mean take this in the wrong way, this is kind of a silly conversation.
This market, physicians have never sent a patient ever for an MRI. They've sent them to the OR to explant the product. You know what I'm saying? If anybody is bringing up this notion of, "Oh, we have full body MRI, but it's only for 1.5T," well, it's been a planted comment by the competitor, right? They don't have this capability at all. It seems to me kind of a little silly. Once again, there are 3T systems out there, and if a certain hospital happens to just have a 3T, we don't want to disadvantage them. We've done the work. We're not afraid to invest the money to get this capability, and we will have it.
This notion about charging or recharging or non-rechargeable, once again, this is a topic that has come up because before we entered the market in the U.S., no urologist or urogynecologist had ever worked with a rechargeable product. Of course, if you've never seen a rechargeable product, then you've got to say, "Well, gee, I wonder if my patients are going to be willing to recharge." Okay. That was a question that came up 120 days ago. Okay. That question does not come up anymore. That is a moot point. It is completely irrelevant that any physician who started with us now knows this is not a big deal. It's very easy. It's not more difficult than plugging your iPhone in, that was not a plug for Apple, by the way, or any smartphone into the wall to charge it. It's not a big deal.
The charging interval that we have today is one hour every two weeks. As we heard from one of the doctors, he's got one patient apparently in his practice that likes to brush their teeth and top off their sacral neuromodulation Axonics system, so they charge for three or four minutes every day. Okay, that's fine. We can certainly do that. We just don't see this issue. Now, there are some patients that a physician may decide that this patient may have some trouble recharging. I would say to you that that's the same patient who's going to have trouble taking the competitor's programmer and plugging two pieces into the wall. If you can't remember to plug something in the wall or to recharge your simulator, you're not going to be able to use any of these products.
Today, there is nothing available in the market that is not rechargeable, okay? We're making a distinction between the implant being rechargeable or the accessories being rechargeable. We have a rechargeable implant and all of our accessories that the patient comes in contact with, for the most part, they don't really need to be recharged. Anyway, enough said about that. This notion about ability to plug in, this is a really, actually, interesting question that you've asked, Kristen, because what we're finding, oddly enough, is that physicians are yanking leads out of patients coming back in for "battery replacements," and they're putting our product in. We expected zero business in this particular area. We expected zero business. The reality is, they feel compelled to tell the patient, "Hey, I've got a new product.
This one, you won't have to come back in three years, four years, or five years to get it replaced. This one is MRI compatible." Patients are choosing our product. It's irrelevant to the doctor if he pulls a lead or doesn't pull a lead. It's going to take an extra five minutes in the OR. To the patient, they're completely oblivious to leads and whether you pull the lead or put a new lead in. It's just not something that they're present to. All they know is, "My physician offered me this new product. It sounds like that's an attractive alternative." They're choosing it. It's interesting. Look, we really do believe that our ability to significantly impact the replacement market with a device that can plug right into an already implanted lead is the way to go.
That's why we've invested our money to develop this additional new version. It is actually turning out to not be as big of a deal on a day-to-day basis as we've seen. I think, Kristen, you've probably now stolen half of the other analysts' questions, but I'll go to the next one, which was, are we seeing any impact based upon the CE mark of this new Micro product? The answer is that to date, what we know is there are three centers in Europe who've done an implant or two, and that's it. The answer right now is no. There is zero impact, and our European customers continue to reorder the product in the same basic rate and pace that they had previously. Just to answer an unsaid question, we've said all along, we're happy that we penetrated a number of these countries.
We said the names, right? We're not expanding our team in Europe. This is not where the action is. 90% of this business is in the U.S. That's what's going to move the meter. We're going to do a really solid job of continuing to support the customers that we have in the Netherlands and England, and Switzerland, and now we just got NUB reimbursement in Germany, so we're going to work to get as many of those 36 centers that applied for the reimbursement to be implanting our products. We are not looking to expand beyond that. Now, I don't want to insult our Norwegian friends because we did get a green card to operate in that country, and we have delivered some good orders there. That's as far as we want to go.
The other markets, they're so small that it just doesn't pay for us, and the margins are nowhere near as good in Europe as they are in the United States. Those are all the reasons. From a commercial standpoint, we've seen absolutely nothing to date. Maybe that'll change as time goes on and so forth, but that's where we are as of today.
Thank you.
Thank you, Kristen. Appreciate all those questions.
Thank you. Our next question comes from the line of Larry Biegelsen with Wells Fargo. Your line is now open.
Hey, Ray and Dan. Thanks for taking the question. Unfortunately, Kristen took all my questions. Anyway, in all seriousness, just a couple from me.
Sure.
If we pro rate your U.S. number for Q4, we get to about 12% share in the U.S. Number one, do you agree with that math? Do you believe your share has continued to increase in January and February?
Well, 12% of what number, Larry?
Well, if we pro rate what we think Medtronic did in the time that you were on the market, in Q4.
Yeah. What I'm saying is, I'm not really sure the numerator and the denominator. I'm not trying to be difficult, I just don't know how to answer the question of 12%, right?
Yep
You know what I mean? Yeah, it's at least that, I guess. The market is expanding and all that, right? It's a difficult question to answer because we don't have absolute numbers, right? We don't know what Medtronic's annual revenue is. We don't know exactly what that is. The data we have from third parties in terms of looking at the claims data is two years old. It's difficult to get an exact handle on the number of replacement units versus de novo implants. We're in an immature market where there hasn't been a lot of data. It's not like spinal cord stimulation, where you guys have perfect information, and you're able to talk about market share numbers, and you understand the size of the market.
I'm not so sure that Medtronic is going to all of a sudden start to publish numbers that we're going to give the analyst community a better way to say how much market share they're losing. If I had to make a bet, I would bet that you're not going to hear that from them. I think it's going to be difficult for us to answer that question. I'm not trying to be evasive. I just don't have a good answer.
Fair enough, Ray. Just lastly from me, obviously, you guys hit the ground running here pretty hard in the U.S. One of the key questions surrounding the Axonics story is your ability to kind of continue to take share once Medtronic launches Micro in the U.S. in the late spring. What can you say today that can give investors confidence that you'll be able to continue to take share once they do launch Micro in the U.S.? Thanks for taking the questions, guys.
Thanks, Larry. First thing is that one would have to check with the Las Vegas odds makers to understand whether spring is the under and over or not. Okay. That's the first comment. I understand what that corporation is saying about getting a new PMA approved in 180 days, and I wish them luck with that, but I'm not so sure we're going to see that product in the spring. Therefore, it's kind of a mystery product at the moment. We have a little bit of a sense of what some of the elements are of this device now, but it's one of those things where it's a little bit up in the air.
Here's the question that I would pose back, and that is that are they coming to the product with a bespoke product that has gone through design research to determine all the usable aspects of that system, the charger, the patient remote, et cetera. Is that thing really ready for prime time and so forth? Is it a competitive product with our product, okay? That is a question that we don't really know the answer to, okay? I could speculate, but it's inappropriate for me to speculate. That's something for them to answer, not for Axonics to answer. Second thing is, the question is, how's that clinical study going with respect to this new product? The only answer to that question is, oh, there is no clinical study. My question is, why are we confident that our momentum will not slow down?
We've got the gold standard data in this market. We've got a 90% efficacy in a pivotal study where we did not even do external trials on these patients. We just put them right on the table, out of 129 patients, got our implant, 90% of them beat the most conservative numbers in terms of efficacy. We're seeing that actually in reality in our commercial implants. This is not some one-off because we picked good implanters or we cherry-picked the patients. Anybody who would suggest that, it's just bunk, okay? We have an unassailable study. The physician community is now pointing to our study as the best in class, in effect, gold standard for urinary urge incontinence patients for sacral neuromodulation. I think our competitor, which we have a lot of respect for, has a lot of wood to chop.
The fact is, it's really interesting that they're deciding now to come out with a small rechargeable product. If nobody wants to recharge, why are you coming out with a rechargeable product? If long-lived device is not important, why is that device long-lived? If constant current is not better than voltage control devices, why is that what you're coming out with? Is it really true that all of a sudden nobody is interested in clinical data? I could tell you that from trafficking with these physicians now for the last five and a half years, that they believe clinical data is important. I think those are all the reasons. If we have to give confidence to institutional investors that we're not going to give back any customers, here's what I could tell you.
Every single day, the number one thing our team is focused on is on making sure patients do well with our therapy and making sure they get the support that they need, not only in the OR, but in programming the patient and that we're responsive to whatever the needs are in the market. That's the only comfort I can give people. We are not giving up any of these customers once we've gotten them. We believe, based on what they're telling us, we've created the perfect product for sacral neuromodulation. It's kind of an easy throwaway line, but my view is if these guys come out with something that's better than the perfect product for sacral neuromodulation, then they deserve to get the business. We're not going to give it up. We worked hard to get to this point.
This is not an overnight effort. This is not something we pulled off the shelf and dusted it off and are talking about it. This is something, as you know perfectly well. We spent a lot of time and treasure in developing the product, and we are not resting on our laurels. We're going to continue to go forward. I really appreciate this question because I know this is pretty much now the new question that's on everybody's minds in the institutional investor community. God knows that question has changed over the arc of us becoming public. We do know that's a question that people have in their minds. Look, there's only one true answer. Time will tell.
All right.
Time will tell.
All right, Ray. Thank you for the comprehensive response.
Thanks, Larry. Thanks.
Thank you. Our next question comes from the line of Danielle Antalffy with SVB Leerink. Your line is now open.
Hey, good afternoon, guys. Thanks so much for taking the question. Just a follow-up question on the market growth potential here, Ray. I know it's very early. It's going to be anecdotal. You already gave some anecdotal commentary around it. If this was a market that has been growing, maybe let's talk about the centers that you're in. If volumes there have been growing a certain percentage, do the physicians that you're talking to or selling to, are they seeing two times that growth on a weekly basis? Help us maybe quantify what you're seeing. I have one follow-up on the market.
Okay. I think that the best way to answer this question is really to go back to the work that the analyst community has done. I know that there were three surveys that were done by various different analysts on this call today, where maybe their sample sizes weren't huge, but I heard 40 to 50 physicians each were surveyed. They indicated that they expected the market to grow 15% or 20% this year. When we did our own surveys in the seminars that we did with more than 300 physicians, they indicated that they expected 20%-40% growth. I think 20%-40% may be very optimistic. Granted, our group was more biased because they came to our seminars. I do believe that this number, of 15%-20% is real. That looks to me about five times what it was historically.
That's what we're hearing.
Yeah.
It just gets back to more patients saying yes. I think really that's the issue. I think that if I'm modeling and I'm trying to model, I think that that's probably the right zip code.
Okay. That's really helpful. Just a follow-up longer term, I don't know if you can answer this question or not, as we think about this is third-line therapy at this point, you finally are driving innovation in the sacral neuromodulation market. I guess I'm just curious about your thoughts as to whether this could move up from third-line therapy. If so, what's necessary? You have very strong data in hand. Is that enough to eventually get it further up the curve or do you need to do registry data? Maybe talk about the potential there, if there is any.
I think, it's just not our focus. We're not in the business of changing the practice of medicine. It's really beyond our reach. It's the American Urological Association, the AUA, is the ones that have to change the guideline. We don't have the resources to start lobbying efforts. Will it change over time? Probably, but it's unknowable. The reality is that if you just look at the number of patients right now today, under the current guidelines, we estimate that there's probably five or six million patients in America, primarily women, average age 55 years old, that have gone through a differential diagnosis. They have overactive bladder or dual incontinence or fecal incontinence. If they had the OAB, they've been given some drugs, maybe one, maybe two. They may have gotten some Botox injections, they may not. These are the candidates for our therapy right now.
This is a huge market opportunity. If you look at it, this rivals what the folks at Inspire Medical are talking about in terms of the $6 billion opportunity. It exists today. No changes to third-line therapy guidelines or AUA. That is the reality today. I think if there's one piece of the puzzle that institutional investors have not fully appreciated is that this is an untapped market with lots of potential for growth, and this market is going to expand. Dan and I have been saying this since the first day we met with any institutional investors back in May of 2018. We believe this market is going to double, and whether that takes three years or four years or five years, mark our word, that's what's going to happen. We've seen it. We've been around for a while. We've been at this game for almost four decades.
We've seen this happen time and time again. This has all the characteristics of a breakout market. It all starts with competition, innovation, right? You can't increase a market with a fussy product in a monopolistic environment, right? That's what's going on. We're betting, we're all in on sacral neuromodulation.
Thank you so much.
You're welcome. Thank you.
Thank you. Our next question comes from the line of Kaila Krum with SunTrust. Your line is now open.
Hi, Ray and Dan. Thanks for taking our questions.
Sure.
You mentioned you had 200 accounts on board in Q4, and then you're in over 300 institutions now in the U.S. My question is, how many accounts do you think you need to hit the full year consensus estimate of $88 million? Should we expect that you continue to add centers at this rate going forward? How do we think about that metric that drives our model?
Yeah. Sure. I think we needed about 220 to make our numbers, is the calculation that we had. Now you can get a sense about why we're bullish about the annual number. Every single day, we're adding new accounts. Every single day. As I mentioned, I didn't give hard numbers, but we have literally dozens and dozens of IDNs, ambulatory surgery centers, group practices that are still in the hopper with us. We don't yet have a green card to do business in their facilities. We're not getting resistance. It's just that it takes time to be able to work through all these agreements. We got a lot of blue sky ahead of us. We expect to continue to add accounts. I fully expect that you'll hear bigger numbers from us when we report our first quarter results. We're quite confident and bullish.
Bottom line is, I know, Kaila, you've recently been at one of our events. You've seen it with your own eyes. The docs like our product, and they want to use our product, and they like our company, and they like our marketing materials, and they like our people, and they find that we're earnest, and we're honest, and we're hardworking and vigilant about what we're doing and serious about it. We're 100% focused. We only have one business here at Axonics, and that's sacral neuromodulation. That's it. That's our business. I think it's really well appreciated by this physician community. It's been a long time coming. I think they're grateful that we're here.
If we showed up with some stuff that doesn't work and we didn't provide the support and we weren't giving them a good product at a fair price, it'd be a whole different story. We're not making these rookie mistakes as a company.
That makes a ton of sense. You guys mentioned you doubled the size of your field specialist force, which I think is a big deal, and it's a big headcount increase. Can you just elaborate on your strategy there, what prompted that strategy, and just how that helps you guys scale and compete more effectively? Thanks, guys.
Yeah. Thanks. That's a really good question. We started the year with 32 clinical specialists, and we have a slightly different philosophy, I think, maybe than some others in that our salespeople, their job is to go out there. They're all expert. They can support counts. They can do procedures. They can program the patient. In the end of the day, we want them selling. We don't want them stuck in the OR. Okay? That's the wrong place. Sure, they have to be there for the first couple of procedures with a new account that they opened, make sure that they introduce the account properly to the clinical specialist, of course. They need to then move on to the next and the next. The key thing for us is to have clinical specialists. These are different kinds of people, right?
These are people who, first of all, are usually nurses. 99% of them have come from the spinal cord stimulation business, they know how to program. They know how to deal with patients. We've moved that headcount from 32 to what would be 68 individuals, and we've said all along that that was part of our plan. We're not going to add salespeople. We have 100 territories. That's it. We have 100 territories. We're not adding more territories. What we're going to do is continue to add clinical specialists as the case volume grows. If you've seen that in literally two months of this year, we have doubled the size of our clinical specialist team, that should let people know that we've got a lot of cases to cover. We don't want to disappoint our customers.
We need to make sure that if you've got a case, then we're going to get it covered. If that means that we need to go from 68 to 100, and we need to get to that 100 sooner than later, we'll do it. We know how to hire good people. We know how to train people. These are the right kinds of individuals to really provide the support in these centers. They care about people. They're very sensitive. This is what we need. It's important that we have the right kind of individuals, and we provide the right kind of support. At this point, I dare say we got more feet on the street than the other player. We will continue to make sure that we've got the right headcount.
Thanks, guys.
Thank you.
Thank you. Our next question comes from the line of Adam Maeder with Piper Sandler. Your line is now open.
Hey, guys. Congrats on the quarter, and thanks for taking the questions. Two for me. First, just on the supply chain. I know you've been focused on building and stocking up inventory and adding second-source suppliers. I think you've already stockpiled some batteries for the rechargeable devices which come from China. Just maybe a level set us on how you're feeling about supply chain and just any proactive measures you're taking to prevent any supplier disruption. Then I had a follow-up.
Yeah, I just want to make sure that people don't get the wrong impression about what you just said. The battery that goes into our implantable device is not from China. Okay? What we have said is that we source a particular battery that goes into our recharging puck, and it happens to come from China. I think it's an important distinction. With respect to the rest of the comments, Dan might.
Sure.
May want to add a few words.
Sure. Hi, Adam. I think as we've discussed in the past, we built the supply chain and selected certain large-scale third-party contract manufacturers so that we could place larger purchase orders and increase production quantities from dozens to hundreds to thousands, and this is exactly what we've done. Starting earlier in last year, we started ramping production. As we've mentioned a number of times on this call and in previous calls, the launch has gone better than expected. As a result, what we've done is we've really relied on these third-party contract manufacturer suppliers to just make more sub-assemblies faster. Look, we're ramping. We are continuing to focus on this area.
Ray mentioned earlier on the call that we've hired dozens of people in operations and quality to make sure that we're continuing to manufacture units at the quality that we expect. We are shipping products. Look, it's no surprise for a company in this level of growth at this phase, right? We're waking up every day and just thinking about manufacturing product, getting it shipped, and taking care of these physicians and these patients.
Okay. Appreciate that color. Just for the follow-up, maybe one for you, Dan. Can you help us get a better sense for just absolute level of OpEx spending this year with the additional clinical specialists and manufacturing personnel that you're bringing on board? Just any color there would be much appreciated. Thanks so much, guys.
Yes. No, thanks. In the previous quarter call, we had mentioned that operating expenses for the quarter had, I think, come out at around $25 million. This quarter, we reported $28.1. What we said before was that that number was stabilized. I think, stabilization means this. For a certain level of volume, right? That number is going to remain fairly consistent, although with an increase in unit orders and sales, and as we've mentioned, increasing the number of people in operations quality and in clinical support, what we're going to see is a commensurate increase in OpEx related to that increase in volume. I expect operating expenses to increase, but I don't expect them to increase disproportionate to the rate of the increase in volume.
We are tracking according to plan, and as we get these additional people fully on board in this quarter and next, and are up and running, we'll just continue to report, call it modest to moderate increases in OpEx, but certainly nothing that I would characterize as significant or unexpected.
Okay. That's very clear. Thanks again.
Thanks, Adam.
This concludes today's question and answer session. I would now like to turn the call back to Raymond Cohen for closing remarks.
Okay. Thank you, operator. In closing, I'd just like to say that we're making really excellent progress in the first 120 days of our U.S. launch and the other strategic initiatives. We're confident about the future of the company, and we're going to continue to keep our heads down and focus on doing the right thing every single day for our patients and our customers. We really appreciate everybody's interest in Axonics and the support that we've gotten from the analyst community, institutional investors to date. Thank you very much, and I wish everybody a happy and healthy rest of your day.
Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
