Peter Miller
Thanks very much, Jonathan, and good morning, everybody. We appreciate you joining us this morning. This clearly is an exciting time for our company, We believe that we made strong progress in the first half of 2021 towards our two core objectives, driving enhanced revenue growth and successfully completing our chronic sinusitis pivotal trials that have potential to unlock significant new value. Starting on slide three, I'd like to begin by highlighting four key takeaways from today's presentation. First, our Q2 2021 financial performance was aligned with our full year guidance. Second, We believe there are multiple opportunities that will continue to support revenue growth in 2021. We're very excited about the emergence of a stepwise care paradigm for the treatment of chronic rhinosinusitis with nasal polyps, much as the medical community has adopted in other disease areas such as asthma, hypertension, and pain. This paradigm was the subject of an algorithm published in June in the International Forum of Allergy and Rhinology, authored by leading independent experts from both the ENT and allergy thought leader communities. that highlighted the role of Exhance in a stepwise care. Importantly, this expert group recommends that Exhance be considered in two situations. One, when traditional nasal sprays have been tried and found to be inadequate before a patient progresses to a higher tier care such as surgery or biologics. And two, when symptoms recur after surgery. As awareness of the stepwise care paradigm continues to grow, we believe it could be very beneficial for the continued adoption of Exhance by physicians. Another factor that we believe could support revenue growth in the remainder of 2021 is improvement in patient flow and physician access. Although market conditions have improved during the last several months, we've not yet seen a complete return of the number of diagnostic visits by patients to ENT and allergy offices. Additionally, our sales representative access to those physician offices also remains below pre-pandemic norms. Although the future pandemic environment is not entirely clear, We believe our specialty physician environment will remain relatively stable and potentially improve in the last months of the year with respect to both patient volumes into offices and our representatives' access to those offices. Given the historical high promotional response we have seen with ExHance, we believe this could be beneficial in driving growth. In addition, we continue to see potential to get more benefit from our partnership with Caleo as the Potemic environment potentially improves access for their representatives as well. Finally, we believe there is potential for improvement in the average number of prescriptions filled per patient per year as a result of the changes we made to our co-pay assistance program. Third, we completed an enrollment in our first pivotal clinical trial evaluating enhance for the treatment of patients with chronic sinusitis in July and remain firmly on track to have top line results from this trial in first quarter of 2022. We are now focusing all of our recruitment efforts on the second pivotal trial, which we expect to complete enrollment by year end and have top-line results in the second quarter of 2022. And fourth, we are very enthusiastic about the opportunities for growth that successful chronic sinusitis trials would create. Xhance could be the first drug ever to be approved by the FDA for the treatment of chronic sinusitis. We believe these trials could not only It could not only be a breakthrough for the approximately 30 million patients in the U.S. who suffer from chronic sinusitis, but also a game changer for our business. Chronic sinusitis data could create a multifold expansion of the target population, could further increase product differentiation in our current physician audience, could be a strong basis for engaging a partner to help reach a substantially expanded physician audience in primary care, can improve ex-U.S. opportunities, and therefore, significantly drive additional value for the company. Turn to slide four. We had strong performance in second quarter 2021, and I will briefly touch on the year-over-year growth highlights on this slide and the next. In second quarter 2021, there were approximately 29,000 new prescriptions for Ex-Hance, a 55% increase compared to second quarter 2020, and the highest number of new quarterly prescriptions for Ex-Hance since launch. While the market increased 19% over the same period, as the second quarter of 2020 was the peak of pandemic-related restrictions, we're pleased with the disproportionately high increase in new prescriptions for expense. What's important here, though, is that in addition to increasing the number of new prescriptions, we've also improved the quality of our new prescriptions due to changes in our copay assistance program. This has increased the proportion of covered patients filling first prescriptions, which we expect to drive higher refill rates and improve average revenue per prescription. The total number of enhanced prescriptions in the second quarter of 2021 was approximately 82,900. This represents 33% growth over the second quarter of 2020 in a market environment which increased 5% over the same period. Turning to slide five, enhanced market share increased from 4.4% in second quarter of 2020 to 5.4% in second quarter of 2021. As market volumes potentially return towards the pre-COVID baseline in the later part of the year, we're focused on holding onto or adding to the gains we've made in market share. Breath and depth of physician prescribing is measured by the total number of physicians who have patients filling enhanced prescriptions increased from second quarter 2020 to second quarter 2021 as well. Regarding breath, in second quarter 2021, approximately 7,200 physicians had a patient fill at least one prescription of Exhance, an increase of 16% compared to second quarter 2020. Regarding death, the number of physicians who had more than 15 Exhance prescriptions filled by patients in a quarter has grown even faster, with that number increasing by 38% from second quarter 2020 to second quarter 2021, with more than 1,400 physicians now in this segment. In a few moments, I'll provide some closing remarks but I'll first turn the call over to our CFO, Keith Goldan, for comments regarding second quarter 2021 and perspectives regarding our corporate guidance.
Jonathan
Thanks, Peter, and thanks to everybody for joining us today. Turning to slide seven. As we reported, Opti-Nose recognized $18.4 million of enhanced net revenue, an increase of 79% compared to the second quarter of 2020. Based on available prescription data purchased from third parties and also on data we received directly from our Preferred Pharmacy Network, enhanced average net revenue per prescription for the second quarter of 2021 was $221, an increase of 35% compared to $164 in the second quarter of 2020. The year-over-year increase in revenue per prescription is driven by the absence of the one-time assist program that was available to patients in the second quarter of 2020, combined with changes earlier this year to our co-pay assistance program. These changes were intended to increase revenue per prescription by reducing the rate of growth in prescription fills by commercially insured patients and plans that do not cover exams, while sustaining growth in covered plans. Data suggests the changes had the targeted effect and we expect continued beneficial effect on revenue per prescription going forward. Moving to slide eight. Our guidance for full year and the remainder of 2021 is unchanged, with the notable exception of revenue per prescription where we have increased our expectation. First, in light of growth prospects for both prescriptions and revenue per prescription, we continue to expect enhanced net revenue will exceed $80 million for full year 2021. Prescription volume factors supporting this could include the place of enhanced and stepped care being embraced by more physicians in our target audience, potential improvement in the average number of prescriptions filled per patient per year that result from the changes we made to our copay assistance program, The changes we made drive a greater proportion of prescriptions coming from patients with insurance that cover exams. As I said earlier, our data indicate these patients fill out a greater number of prescriptions per year. Improvements in patients visiting physicians' offices and our territory managers' ability to visit those offices, as well as the Caleo co-promotion. Second, with respect to the expense net revenue for prescription, We expect to see improvement over the remaining two quarters of 2021 relative to the first half. And for the full year 2021, we now expect enhanced net revenue per prescription to exceed $200. Previously, we expected full year 2021 to exceed $185. And finally, for the full year of 2021, we continue to expect operating expenses to be in the range of $137 to $142 million, of which approximately $10 million is expected to be stock-based compensation. Total operating expenses excluding stock-based compensation are therefore expected to be in the range from $127 to $132 million. I will now turn the call over to Rami to discuss our development programs.
Peter
Great. Thank you, Keith. Turning to slide 10. I'd like to briefly remind you here of the basic design of our chronic sinusitis trials. The two pivotal trials are similar six-month studies evaluating both of the FDA-approved doses of exams in a population with chronic sinusitis. Turning to slide 11. Regarding the two pivotal trials, which comprise our chronic sinusitis registration program, as discussed earlier, we recently completed enrollment for the first trial, study 3205. That puts us firmly on track to have top-line results in that first quarter of 2022. All of our recruiting efforts are now focused on the second trial, Study 3206. We expect to complete enrollment for Study 3206 in the fourth quarter and to have top-line results in the second quarter of 2022. We previously reported having performed a planned, blinded interim analysis to compare the observed variance in the first of the two hierarchical co-primary endpoints in Study 3205 to the variance that we had assumed during initial trial design. In June, we completed a second similar planned blinded interim analysis to assess the variance in the second of the two hierarchical co-primary endpoints in Study 3205, the average opacified percentage of the average percentage of opacified volume, which is the CT scan endpoint. We assessed the variance in the change scores from baseline to week 24. Like the first interim analysis, this analysis was intended to assess whether the variance assumptions in our a priori sample size calculations were consistent with the actual variance being observed in the trial. The second analysis was performed on data from approximately one-third of all patients projected to complete the study. The result was that the observed variance was lower than the variance that had been assumed for the purposes of sample size estimation during the initial study design. Given this result and the similar result previously reported for the first hierarchical co-primary endpoint, we reduced the sample size in the study from 378 to approximately 330 patients in Trial 3205, while maintaining our originally targeted statistical power for the final analysis. We plan to allow a similar blinded interim analysis for Trial 3206 when sufficient data, including a six-month follow-up CT scan data, becomes available. Moving to slide 12. Regarding OPN019, our product candidate with potential utility for treatment or prevention of COVID-19 and for preparedness against future pandemics. In early July, we received approval from regulatory authorities in Mexico to proceed with conduct of a randomized adaptive proof of concept single dose study to evaluate change in viral load after use of OPN019 by adults with COVID-19. Final approval from the regulatory authority took longer than anticipated at the time of our last earnings call, but study drug was made available in Mexico, and the study is now open for enrollment. Given the design of the study and the endpoints to be evaluated, we expect to have initial results very shortly after each cohort completes enrollment. Recent news concerning COVID variants and breakthrough infections in vaccinated people leads us to believe that there may be a useful rule for a product like OPN019 to address the evolving pandemic, even in the context of widespread vaccine availability. As previously noted, despite the excitement that we and others have for the potential value of OPN019, we are aware of the need to maintain sharp organizational focus on growing exams and on completing our chronic sinusitis trials. Therefore, when data from our pilot study becomes available, we anticipate seeking grants, partnerships, and or other sources of capital to support further development of OPN019. Before I turn the call back to Peter for closing remarks, I'd like to take a few minutes to put a brief spotlight on the significant opportunity that we believe will be created if we are successful in developing exams as the first FDA-approved drug treatment for chronic sinusitis. So turning to slide 14. We believe successful chronic sinusitis development plus engagement with a primary care partner, could enable promotion of EXCHANCE to up to 30 million patients who have either nasal polyps or chronic sinusitis. Our chronic sinusitis program is important because although we are driving strong growth with EXCHANCE's first indication in our called-on specialty physician audience, there is greatly expanded potential ahead of us if our CS trials demonstrate efficacy. Today, EXCHANCE promotion is aimed at a patient population of approximately 1 million, who suffer from nasal polyps and are actively treated in the specialty setting. We are driving strong growth in that context, as evidenced by our expectation for at least $80 million of ex-hance net revenue this year, which equates to more than 65% growth compared to full year 2020. However, a chronic sinusitis indication would triple the size of the patient population for which we promote ex-hance within our specialty audience, an audience where we continue to grow physician preference share to approximately 3 million patients Even more potential lies in the fact that chronic sinusitis paves the way for a primary care partnership because the primary care setting is where chronic sinusitis patients seek treatment first and most often. A primary care partnership would enable active promotion aimed at a total population of 10 million patients who are actively seeking treatment, 10 times the patient audience we target today in the specialty setting. In addition, we believe that up to 20 million more patients suffer from the symptoms of chronic sinusitis without regularly seeking treatment from a physician today, possibly because they do not want surgery or do not feel there's anything new that their physician can offer them that they cannot buy on their own. This large incremental pool of patients has potential to be activated by a primary care partner, for example, by direct-to-consumer promotion. This results in a total patient population of up to 30 million for whom Ex-Ans may be a suitable treatment option. And that's an enormous increase compared to the approximately 1 million patients who have nasal polyps and are treated by the specialty physicians that are the current focus of our promotional sales efforts. As a result, we believe there's opportunity for significant value creation through a primary care partnership. I'll now turn the call back over to Peter for closing remarks.
Peter Miller
Peter? Thanks very much, Rami. Before moving to Q&A, I'll take a moment to reiterate that we're pleased with the momentum we have built in second quarter 2021 and are laser-focused on continuing to grow, enhance, and completing our chronic sinusitis trials. Thank you, and now we'll open the call up for Q&A.
Operator
Ladies and gentlemen, if you have a question at this time, please press the star and then the number one key on your touchstone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the town key. Your first question comes from the line of Gary Natsman with BMO Capital Markets. Your line is open.
Gary Natsman
Hi, thanks for taking my question. This is Evan Hua, filling in for Gary Nachman. My first question is, have you seen a dramatic change in the number of patients in PICU for the key prescribers of exants? How much more room for recovery is there? And how do you expect patient volumes to trend in the back half of the year?
Peter Miller
You know, I think the best place to look at to answer that question, this is Peter, is in the new growth in the new prescription category in the second quarter versus last year and versus the prior period. And, you know, what we've seen, you know, tracking sort of new prescriptions, which really is the best indicator of sort of how patient flows are going into offices. And this is for the category, not just enhanced. We have a very significant decline in the second quarter of last year. And since then, you've seen a category that has recovered on new prescriptions, but frankly, it didn't quite reach the levels of 2019, sort of a non-pandemic year, if you will. So, while there certainly has been recovery and anecdotal comments from physician offices suggested, you know, patients really have returned. There certainly is an opportunity for continued growth in patients returning. By the way, anecdotally, we do hear that masking and other things did sort of limit the number of patients who had exacerbations, chronic chronic sinusitis patients who had exacerbations, which potentially limit our audience even a little bit more during that period. But to answer your question, there certainly is room for more patient volume returning in the back half of this year. Obviously, there's some effects currently with the Delta variant, but You know, our expectation is there certainly is more room and minimally we believe will be at least a stabilization at the point we're at right now.
Gary Natsman
Great. Thanks for the comment on that. And I have another question. And in terms of, you know, could you provide some more color around the new treatment algorithm for XANs recommended by experts? Yeah. Have you seen any initial impact on KLL community? in terms of prescribing a behavior, and how does that fit into your marketing strategy going forward?
Peter Miller
Yeah, Rami, maybe I'll let you start, and then I'll follow up with some thoughts.
Peter
The algorithm, as we highlighted earlier, the algorithm identifies ex-hance as a treatment consideration at two key points. After you've tried sort of a standard inhaled nasal steroid, you know, like the type you can buy over the counter, and before you escalate care to a higher tier, like surgery or an injected biologic. And then again, at a second point in the algorithm, if symptoms are recurrent after surgery. Our anecdotal feedback from a variety of thought leaders in the area is that there's a pretty widespread concurrence with the positioning of the pants in both of those places. And we do, of course, see the product used in both of those places, and we hope to see adoption increased in both places. as the algorithm becomes more widely disseminated.
Peter Miller
Yeah, the point I'll make in terms of adoption in the market is that we really just started promoting the algorithm in the latter part of June. So any impact of the algorithm is really not yet seen in any material way in our volumes, if you will. We are hearing very encouraging things. And the part that's exciting to us about this is, The group of physicians that have adopted the algorithm is our believer segment. So of the physicians we're targeting, roughly 10,000, only about 1,400 physicians have really adopted the algorithm, which means that we believe this expert group of physicians giving this kind of recommendation, if you will, for where Xhance fits in the treatment algorithm could be a very potentially strong way to influence the balance of people who have not yet really adopted the algorithm in their practice. So we're very excited about it. We just were at a big meeting with some ENT physicians a couple weeks ago. There's real general enthusiasm. The algorithm is being presented in many of the presentations that were being done by people in presentations. And, you know, we look forward to the ability to really grow the business behind this recognition.
Gary Natsman
Thanks for taking my question. Congrats on that.
Operator
Thank you. And your next question comes from Brandon Fulks with Cantor Fitzgerald. Your line's open.
Brandon Fulks
Hi. Thanks for taking my question, and congratulations on all the progress. So IQIA data suggests that its harm descriptions are coming in similar volumes from allergic rhinitis, chronic sinusitis, and nasal polyps. Given this, what's the value of the CS indication for your current target? Thank you.
Peter Miller
Rob, I'm going to have you start, and then I'll add some comments at the end here.
Peter
Great. Thanks for the question, Brandon. So the IQVIA data on prescribing by diagnosis in this specific category has limitations that really constrain its usefulness for understanding this issue, maybe different from other categories. Our market research and our experience in the market to date suggests that although a minority of our prescribers choose to use the product across indications, which makes them some of our largest prescribers today, a large majority of our called-on prescribers do meaningfully limit their use to the nasal polyp indication, which is in part a result of our current promotional efforts, which are limited to nasal polyps. If Exhance is approved for a much broader indication of chronic sinusitis, we anticipate expanded promotional efforts will produce substantially increased depth of prescribing in most of our currently called-on audience. Furthermore, as the first and only product for the treatment of chronic sinusitis, In that scenario, we believe there's potential for facilitated payer negotiations and coverage, which will also further lower perceived insurance barriers to physician adoption. So overall, we think that there's a significant volume potential associated with the new chronic sinusitis indication and physician prescribing in the specialty audience.
Peter Miller
Yeah, and I'll add to that, and Rami, I think, covered it very well, Brandon. Thanks for the question. Historically, we've said that outside of the believer segment, that really, as I said earlier, has adopted not only the algorithm, but really is using our product in a broader group of patients than nasal polyp patients, as evidenced by the fact they have a very high share of total intranasal prescriptions that are written, which means, in essence, they have to be using it a good bit broader. But in that dabbler segment, as we call it, We've historically said that insurance is one of the key factors that sort of limits a physician, writing it more broadly. And to be clear, it's physicians' belief that our insurance is not as good as it really is. And as we say all the time, we really have good insurance coverage of not only 75% to 80% of insurance lives covered, but we really have very few limitations to indication in the coverage that we have. We have pretty wide and broad access. However, many, many physicians believe that plans limit our product to nasal polyps, which, as I said earlier, that's not the actual situation, but it is a limitation. So we believe the CS indication, in essence, takes that issue away and then really lets our sales reps go in aggressively and say, look, we have this indication. and therefore there are not the limitations that you think are in place. And by the way, as evidenced by the fact that we're growing the believer segment, we are chipping away at these perceptions by the fact that we're growing the business, but the indication will eliminate the issue altogether. And as Rami mentioned earlier, by the way, the part that is probably the most exciting part of the indication is opening up the audience to another perspective you know, 50,000 physicians treating, you know, 7 million patients, you know, significantly more patients than our current specialty audience that we think can be accomplished via a primary care partnership. So we are very, very excited about the potential of the CS syndication.
Brandon Fulks
Great. Thank you very much. That's very helpful. I appreciate it. Kala?
Operator
And your next question comes from Don Van Bosby with RBC Capital Markets. Your line is open.
Don Van Bosby
Yeah, great. Good morning, guys. This is Steve on it for Dan. Thanks for taking our questions here. Two for me, and I'll just ask them up front here. The first is I just want to hit back on the guide. You know, based on results, we got implied $50 million in the back half of the year. Maybe you can talk to what's giving you confidence that you're going to be able to exceed that $80 million threshold. Maybe talk about if there's any seasonality you're expecting in 3Q or just some of the assumptions you have built into the guide with regard to COVID and the Delta variant. And then my second question, too, just with regard to Dell's access to physicians, you know, any colors of what percent of reps are seeing face-to-face interactions and, you know, maybe some trends you're expecting in the back half of the year? Thanks.
Peter Miller
Yeah, I'll start. Keith, maybe you can add, you know, some commentary as well. But there's obviously two things that drive, that we believe are going to drive revenue growth. The first that we've commented on is we've seen a really nice increase in average net revenue per prescription. So that was just a very sort of nice improvement that we've seen. And it was not – this is something that's fundamental because of changes that we made in our copay assistance program. So we have that as a very strong tailwind. But relative to your comment on volume, We feel really good about the ability to grow volume in the back half of the year for the reasons that Keith identified in the script. You know, I'll reiterate them. Number one is the algorithm, you know, our ability. And actually, maybe I'll back up, Steve, because you asked first about the environment, and maybe I should start there. You know, clearly, it's hard to predict what the environment's going to be like with the variants and all the rest. You know, we think that if you look at what's happened to our access and patient flows, I covered this a little bit earlier, but there was a significant impact, obviously, on both access and patient flow in the second quarter of last year. You started to see, you know, a growth, if you will, in both areas into about the October-November timeframe. And since then, we've sort of been stalled. And there's improvement, but we're not quite at the level that we were at pre-pandemic. By the way, despite the improvement that you saw in the spring of this year in the general environment, our specialty office environment didn't dramatically improve from the January, February, March timeframe. As we look forward, we don't think it's likely to get worse, our specialty office environment relative to patient visits as well as rep access. You know, we don't have a crystal ball like anybody else, but we believe there certainly is the possibility of an improvement. And I'll answer your second question right now, then I'll go back to other growth drivers. Our target is to make eight face-to-face calls. We found, by the way, that face-to-face calls really are just that much more effective than virtual calls. And virtual calls can be effective, but face-to-face are more effective. We're right now at about six. So we are not where we want to be, and that's largely because of the environmental issues that I talked about just a moment ago. And importantly, I sort of said this in the call, when we have access, we move our business. We are very responsive to promotion when we get the right number of calls on the right number of physicians. So we think BACF will be minimally stable from a specialty audience environment, potentially improvement in the latter part of the year, depending on what happens with the COVID, the Delta and other variants. More importantly, though, we have other factors that are going to drive growth. The algorithm is, we think, you know, potentially a game changer in the near term of our ability to get broader adoption by a bigger number of physicians. As Keith mentioned, the changes in the copay program not only provide value in average net revenue prescription, we're seeing a real potential nice impact on refill rate because a higher proportion of our new patients are covered versus uncovered, and we see substantially higher refills in people who are covered versus not covered. So obviously you should see a real nice impact on refill rate. We think we've not yet seen the full value we can get from the CLEO promotion. So you put all that together, and, yes, we are confident in achieving $50 million in the back half of the year.
Don Van Bosby
Great, guys. Really appreciate the call there.
Operator
And your next question comes from Ken Gashatori with Cohen & Company. Your line's open.
Ken Gashatori
Hey, Peter. A really great job by you and the team. I want to talk about the CS indication and the partnering discussions for primary care. It really seems as if we're almost looking at two kind of distinctly different products. And what I mean by that is, a partner is going to need to do DTC like you indicated, and you're going to need to have broad access, and there's going to need to be kind of mutual, I would think, coverage decision, co-pay assistant decisions and programs like a real intimacy when you're dealing with such an opportunity and dealing with a partner. So I was wondering if you could talk about that a little bit and maybe as Where these negotiations stand, would a partner not be looking to you to maybe even buy out the whole company? It just seems like a massive opportunity and an intimacy with that partner that would be unique and distinct than what we normally deal with. And again, congratulations on all the progress and very much looking forward to the CS indication.
Peter Miller
Well, Ken, thanks very much for the question. By the way, I'm going to reiterate what we said before, but we are really excited by this indication because of the potential value in the specialty audience that I think Rami did a good job of answering the question from Brandon because I don't think enough people are realizing that there's real value in the indication in the specialty audience. But as you're highlighting, Ken, it's a real game changer. If you think about the significant number of patients over 7 million patients currently being treated in primary care with another 20 million people who've likely lapsed because of you know inadequate good therapies it's a big opportunity um and you know for that reason we're very very excited about it you know relative to the partnering discussions because of the size of the opportunity i'll say cam we're very confident we're going to get a primary care partner and um you know, relative to the question about, you know, the intimacy that would be needed in managing a relationship, a partner relationship. Again, we're confident that we're going to be able to manage that. You know, and candidly, Ken, it's going to come down to the economics. You know, if we get the economics that can be expected relative to a primary care partnership, there's going to be a real motivation on our part to make sure that we have a really very strong working relationship with a partner. So, you know, as I said, we're feeling great about the opportunity and very confident we will get a primary care partner.
Ken Gashatori
Peter, when you're thinking about timing, obviously we need the data, but can you give us a sense of, you know, where we stand in discussions and maybe timing we should be anticipating?
Peter Miller
You know, Ken, I'm not going to comment on those discussions. I'll just say that, you know, I'll reiterate, you know, we're very confident we're going to get a partner.
Ken Gashatori
Okay, great. Thanks again. Congratulations again. Thanks, Ken. Appreciate it, Ken.
Operator
All right, and then our next question comes from David Ansellin with Piper Sandler.
David Ansellin
Hey, thanks. So in the nasal polyps indication, certainly clear that you have room for significant further penetration there. So just within that indication, can you talk about the need potentially for expansion of DTC activity over time and the extent to which that can activate patients? Really more of a long-term question regarding DTC within that setting. And then secondly, can you just comment on how aggressive you'd like to be regarding the addition of another asset whether it's a commercial stage asset where you can leverage your sales infrastructure that you have in place or even an R&D stage asset and kind of where your appetite lies at this point in terms of bringing in another asset or multiple assets. Thanks.
Peter Miller
Yeah, thanks very much, David. And I, you know, relative to DTC, you know, as we talked historically, you know, we did do some pilot work with DTC with a nasal polyp indication and, you know, candidly we saw, by the way, we saw terrific patient activation there. The problem that we saw was that we had many patients going into offices, many primary care offices that weren't aware of the product. We also had the issue, by the way, that, you know, because the product is indicated for nasal polyps, when you put that in a DTC ad, there are some patients who sort of raise their hand and say, I don't have polyps, even though they very well may have polyps. So we think the real value of DTC, David, is really with the CS indication. Because if you think about the CS indication, with a partner, we will have broad awareness of the product among, you know, a broad primary care audience. And obviously because the product's indicated for chronic sinusitis, We know from a lot of work that we've done, if you say we have a product for chronic sinusitis, there's 30 million people who say, I have that. The product is the disease is very well known, very well diagnosed. People know they have it. So we think ultimately DTC has the biggest application with the CS indication. Having said that, I think you know we learned a lot in our efforts that we did on the nasal polyp. and have really gotten a lot smarter of how we're doing a lot of our digital efforts, specifically against the nasal polyp group. So I hope that answers that first question. On the second question, David, relative to a new asset, as we've reiterated, right now we are laser-focused on growing enhanced revenue. And we're confident we're going to get to $80 million by the end of this year. We say this all the time, you know, when we get to an $80 million business, that puts us on a run rate certainly north of $100 million, potentially approaching $110 million. And with on the expense side, our CS trials going away, you really can see, you know, the potential to get to break even on cash flow from operations. So, you know, that's our focus right now. That's where we are, our efforts are all sort of targeted. But, you know, there is real value in leveraging, you know, the terrific sales team that we have in place calling on ENTs and allergists. And while we don't see anything happening in the very immediate term, you know, we are absolutely looking to look to bring in some assets in. Eventually, you know, initially, David, certainly the focus will be on commercial stage assets, but then eventually potentially, you know, down the road for pipeline as well.
