Peter K. Miller -- Chief Executive Officer
Thank you very much, Jonathan, and good afternoon, everybody. We appreciate you joining us for our second quarter update. We're excited to discuss the continued strong growth and demand for XHANCE and our plans to sustain that growth.
Starting on Slide 3. I'd like to start by providing an overview of key highlights that we will review in more detail throughout today's presentation.
The lead headline is that our commercial team has once again delivered strong growth in the number of XHANCE prescriptions. Second quarter 2019 marks the third consecutive quarter in which XHANCE prescription quarter-over-quarter growth was 50% or more. Importantly, this growth is not just from new prescriptions as both new prescriptions and refills are growing. Also encouraging for our long term business potential is that while growth has been strong over the past few quarters, there remains tremendous upside potential for XHANCE. We are steadily growing both prescriptions and share, but the market is so large that we believe we are just starting to scratch the surface of the overall market potential.
In second quarter, we estimate the average net revenue per XHANCE prescription was $197, up from $177 in the first quarter. For the entire first half of 2019, that produces an overall average net revenue per prescription of $189.
In light of these results, we continue to believe in our full year guidance range of $185 to $205 for average revenue per prescription. Our growing volume, coupled with an increasing average net revenue per prescription, yielded strong net revenue growth.
Todaym we reported net revenues of $6.7 million in the second quarter of 2019, an increase of 68% over first quarter and we are providing full-year revenue guidance for the first time. For full-year 2019 we expect $29 million to $34 million of XHANCE net revenues. In addition, we are lowering our expense guidance for full-year 2019 and our cash position is strong at $144 million as of June 30th 2019, which allows us to continue to focus on the launch of XHANCE.
And last, we have exciting new post hoc analysis from our clinical trial data showing that patients who are on a traditional intranasal spray for at least 30 days prior to trial entry improved when switched to XHANCE. We believe this analysis has the potential to further strengthen the efficacy message for XHANCE and to provide additional evidence of the value of the product in our discussions with payers.
Turning to Slide 5, we have confidence that our current commercial strategy is strong, as evidenced by the significant growth of XHANCE over the past 11 months. Therefore, we are committed to sustaining and strengthening its core elements, while we also introduce additional accelerators as we move forward. Key objectives of our integrated commercial strategy include communicating how XHANCE is differentiated on efficacy, driving new patient starts within our target nasal polyp patient type and supporting patient access and affordability. While we have many elements that are successfully driving the strategy, we've highlighted several areas that have potential to continue to drive growth.
One example I mentioned earlier is compelling data from a new post-hoc analysis from our pivotal trials that I will describe in the next slide. We also have a growing library of nasal endoscopy videos that we are sharing with physicians to tangibly illustrate the the effect of XHANCE on nasal polyps in a compelling way that can be observed directly. Both will add to the already strong case that is helping differentiate XHANCE on efficacy when we meet with physicians.
The market for XHANCE is sizable. So despite our uptake, the opportunity to start new patients on XHANCE remains very large. Therefore, we have added new drivers to support this component of our commercial strategy as well. At the start of second quarter, we increased the number of sales territories for XHANCE, by 25%. We are encouraged by the initial progress of the territory managers we hired to promote XHANCE to a new universe of high potential target physicians.
In addition, we deployed a new seven-day sample in May, that is in my opinion better described as a starter kit for new patients. Paired with prescription the seven-day sample is enough product for the patient to start and maintain treatment while they have the first prescription filled. I'll detail this more in a moment. I'm also excited to announce that we have initiated a multi-channel DTC pilot in Charlotte, Cleveland, Hartford. The pilot is designed in a test versus control fashion to help us inform -- to help inform us about the potential for XHANCE if also marketed directly to patients.
Third; we invest a great deal of time and energy in understanding and improving market access and affordability. In today's environment, this is vital to drive product adoption by both patients and physicians. Our primary opportunity for XHANCE is with commercially insured patients and we estimate that nationally based upon third party syndicated data and internal analysis, the greater than 75% of those lives are currently in a plan that covers XHANCE.
In addition, we recently signed a contract with one of the largest health plans in the country that enables expansion of our target physician universe. In addition to the lives covered by commercial plans, we are also making progress negotiating signing contracts for XHANCE to benefit patients covered by Medicare and Medicaid plans.
Turning to Slide 6. Efficacy is an important reason for physicians and patients to start using XHANCE and efficacy therefore is a key part of our commercial messaging. Because XHANCE is a nasal steroid differentiated by our unique breath power delivery system, one question we get is whether the product is effective in patients who still have symptoms despite the use of other nasal steroids in a traditional delivery system.
Because almost all patients in our pivotal trials have previously tried nasal steroid treatment, we are helping address that question with a new analysis of the 30% of patients who reported use of a nasal steroid in a traditional delivery system for at least 30 days immediately prior to entering the trials.
All patients had bilateral nasal polyps and moderate to severe symptoms at trial entry and when switched to XHANCE experienced improvements. Slide 6 shows the improvement of people switching from other nasal steroids to XHANCE on endpoints including congestion and nasal polyp grade. This new analysis is an example of one of the new tools we anticipate using to help further differentiate the profile of XHANCE in the second half of this year.
Turning to Slide 7. Another factor which may work to drive future revenue growth is direct to consumer communication. We've taken a disciplined approach to DTC learning first through a digital pilot that started in November 2018 and ended in April 2019. As our next step, we have launched a multi-channel test market pilot this week in Cleveland, Charlotte, and Hartford that we expect to run into November.
We will evaluate the impact of the upcoming pilot before committing to a broader DTC program next year. However, we believe such a program would be likely to focus on key markets and run during time periods that we believe DTC would be more efficient.
Finally, many of you on the call have asked us if the advertising we are using in broadcast or in the test pilot will be available online. We anticipate that the broadcast ad will be available in several places, including on YouTube and the XHANCE Facebook page next week.
Turning to Slide 8. I am very encouraged by the continued strong growth in prescription volume we have observed through the first half of 2019. The number of XHANCE prescriptions in the second quarter of 2019 was nearly 34,000. This represents growth of 51% over the first quarter of 2019 and is the third consecutive quarter of prescription growth at or above 50%. Moreover, as we enter into the third quarter of 2019, we can report 17% month-over-month growth for July over June, a strong start to the second half of 2019. It is also encouraging for future growth of XHANCE that the overall growth in the second quarter is driven by growth in both the number of new patients and the number of refills and that the proportion of total prescriptions attributable to refills has continued to increase as we begin to see more patients using more months of XHANCE to treat their chronic condition.
Slide 9. We believe there is a large market for XHANCE and that is one reason for significant headroom for long-term growth. One way to, evaluate that potential is with the XHANCE share of intranasal steroid prescriptions written within our target physician audience. To be clear, most of the INS prescriptions written within our target physician audience are for chronic sinusitis, allergic rhinitis and other conditions outside of our nasal polyp indication. But this is a measure of share we track. While the share has grown rapidly by more than a factor of three in 2019 from 0.9% in December of last year to 2.9% in July, the low absolute size of the share illustrates the overwhelming opportunity for XHANCE growth still lies ahead within just our current target audience.
In a few moments, I will update you on our chronic sinusitis program and provide some closing remarks. And now I will turn the call over to our CFO, Keith Goldan, for comment regarding second quarter results and perspectives regarding full year 2019. Keith?
Keith Goldan -- Chief Financial Officer
Thank you, Peter, and thank you to everybody joining today. Turning to Slide 11. As we reported after market close, Optinose recognized $6.7 million of XHANCE net revenue in the second quarter. As noted on prior calls, one of the metrics that we track is average net revenue per prescription, which is calculated by dividing net revenue for the quarter by the estimated number of XHANCE prescriptions dispensed during the quarter.
We believe this is a useful metric to evaluate the net revenue generated per prescription. However, we remind you that this metric is subject to variability, that variability as a result of factors that do not necessarily reflect a change in the price that is paid for an individual unit of XHANCE, including ordering patterns and inventory levels for our wholesale customers and pharmacies that we sell to directly, utilization rates of patient affordability programs, the proportion of patients acquiring XHANCE to an insurance benefit and other factors. Based on available XHANCE prescription data purchased from third parties and data from our pharmacy partners, our average net revenue per prescription for the second quarter of 2019 was $197, which was an 11% increase compared to the first quarter average of $177.
The increase from the first quarter was primarily due to our need to provide less copay assistance as more patients meet out-of-pocket limits following the annual reset of insurance deductibles, commonly in January. Typically, once a patient meets their out-of-pocket threshold for the year, insurance benefits pick up more of the out-of-pocket cost of prescription drugs, which in turn reduces the amount of copay assistance provided by our affordability program.
For the first half of 2019, overall average revenue per prescription was $189, which falls inside the range that we continue to expect for the full year, which I'll review further in a moment.
Moving to Slide 12, as highlighted in our earnings press release, we're providing XHANCEs' net revenue guidance for the first time. We expect full-year 2019 XHANCE net revenue to be in the range of $29 million to $34 million. As a product in launch phase, we waited until the second half of the year before providing full-year guidance in order to have more information regarding product demand and average net revenue per prescription. We may elect to take a similar approach in the future.
In addition, we continue to expect that the full-year 2019 average net revenue per prescription will be between $185 to $205.
Finally, for the second quarter of 2019, operating expenses were $31.3 million. Based on that and our strong commitment to be efficient with our cash, we're reducing our full-year 2019 expectation for total operating expenses defined as sales, general and administrative, plus research and development expenses, to be in the range of $128 million to $133 million, of which $10 million to $11 million is expected to be stock-based compensation.
Total operating expenses, excluding stock-based compensation, are expected to be in the range of $118 million to $122 million. Previously, our guidance for total operating expenses range was $135 million to $142 million. Thus, the midpoint of the new guidance range is $8 million less than the midpoint of the old range.
I'll now turn the call back over to Peter to give a brief pipeline update and closing remarks. Peter?
Peter K. Miller -- Chief Executive Officer
Thanks, Keith. Turning to Slide 14. In addition, the launch of XHANCE, we believe significant additional long-term value could be created by a follow-on indication for the treatment of chronic sinusitis for the purpose of accessing a broader target audience. As we've mentioned before, this is an indication for which we are aware of no current FDA approved drug treatments. It is a condition with very high prevalence, which is treated by substantially larger universe of physicians with guidelines currently calling for off label use of nasal steroids.
In the second quarter of 2019, we initiated the second of two trials and focused on the execution of our plan to activate clinical trial sites. Although multiple sites are now screening and enrolling, we are continuing to add additional investigational sites with an emphasis in the second half of 2019 on activating global sites, particularly for the second trial.
Turning to Slide 16. In conclusion, we are very encouraged by the sustained quarterly growth in prescription volume that we are reporting today. Our achievement of our expected trends and average revenue per prescription and reporting on steady growth and refills is a business driver as well as planned actions to sustain continued growth help round out the picture for today, while our growing yet still modest share penetration is indicative of the large market that offers a great potential for tomorrow.
I look forward to our future updates. Thank you. Now I'd like to open up the call for Q&A.
Questions and Answers:
Operator
]Operator Instructions] Our first question comes from Randall Stanicky with RBC Capital Markets. Your line is open.
Ashley Ryu -- RBC Capital Markets -- Analyst
Hi. Good afternoon. This is Ashley Ryu on for Randall. I just wanted to talk a little bit more about that 2Q number. I'm just trying to understand, Keith, started to see any benefit from the increased sales territories? And can you talk a little bit about the impact, if any, in Q2 from seasonality and the increased sales territories compared to the growth driven by, you know, new prescribers in existing territories, increase of refills, that kind of thing? Basically trying to just understand the "like same store growth" if you will.
Peter K. Miller -- Chief Executive Officer
I'll start and then, Tom, maybe you can answer some color. But thanks for the question. And really, the majority of the growth in 2Q was driven by what we call the old territories, if you will. So the 80 territories that were in place prior to their expansion last April, there was some modest contribution in 2Q of the new territories. But as we said on prior calls, we really did not expect much contribution in 2Q and we really didn't get much contribution to 2Q. We do as I said in the prepared remarks, we believe that really could be an accelerator in the back half of the year, there's no doubt about that. So the growth really was driven by what we call sort of our organic, if you will, territory managers. Relative to seasonality, there really is a seasonal impact and obviously anybody who followed last year know that that's something we talked about. We're very, very encouraged that we grew right through that seasonal impact.
As a result of two things, we were able to continue to grow new prescriptions because of our patient affordability program and most importantly, the great progress we've made on physicians really understanding we have a differentiated efficacy profile. But we continue to just believe that we're going to be able to -- and also refills is the second thing that really contributed to the growth. But, Tom, I don't know if you have anything to add?
Tom Gibbs -- Chief Commercial Officer
Sure. Just maybe a couple of things and thanks for the question. As Peter said, I think we're very pleased with the strong growth that our -- what we call our legacy territory managers were able to generate during the second quarter. Now, with that said, we feel really good about the people that we've hired into the new territories and I'm pleased with the early progress that they are making. So, we know that it takes time for new territory managers to access target physicians to increase product awareness and build appreciation for the clinical differentiation of XHANCE. As they achieve these objectives, we expect them to contribute meaningfully in the back half of the year.
So overall, very encouraged by both our legacy territories as well as what we're starting to see from our new territories.
Ashley Ryu -- RBC Capital Markets -- Analyst
Great. Thanks so much. I just had a few quick follow-ups. Do you then also I guess it expects that seasonality to impact 3Q? I know you mentioned the 17% growth in July versus June. Can you just confirm whether you expect month-over-month growth to kind of continue through 3Q? And then the last thing is just if you can kind of quantify the proportion of refills versus the new patient starts that you see in this quarter. Thank you.
Peter K. Miller -- Chief Executive Officer
On the season, and Tom, again, you can add color, but the trough of the season is really sort of an early to mid July. So, we're sort of through the worst of it, which we're very encouraged by the strong 17% growth we had in July. We should have grew right through that sort of downturn that you see in the season in June and then into July. So from here forward, the category is a seasonality will be a tailwind for us. Tom, anything to add on that with the refill?
Tom Gibbs -- Chief Commercial Officer
Just to give a little bit of specifics on the market dynamics, in June we saw, for the intranasal steroid market, a 17% decline in the market. And then in July, there was basically 0% growth. So as Peter said, the trough of the intranasal steroid market is behind us and we expect to have a bit of a tailwind as we move into the latter part of the third and fourth quarter. On the refill, we're not disclosing at this point in time proportion of refills, although I did mention in my script that because we're seeing very good acceleration of refills, the proportion of refills is growing relative to the overall proportion of total prescriptions. But at this time, it's something that we're not disclosing. I will say we continue to feel very good about our refill rate.
Ashley Ryu -- RBC Capital Markets -- Analyst
Got it. Thank you so much.
Operator
Thank you. And our next question comes from David Amsellem with Piper Jaffray. Your line is now open.
David Amsellem -- Piper Jaffray & Co. -- Analyst
Thanks. So just a couple, so first on the net revenue per Rx, I know it's a little bit early to talk about, but any color on how we should think about 2020? I think as you began the initial launch, you had net revenue per Rx expectations and you talked about it actually being over the $200 range or even a good north of that. So, you know, help us understand and maybe longer term where you think that trend is? That's number one.
And then number two, apologize if I missed this, but can you give us some flavor as to a portion of usage in non-polyp patients and also patients who have allergic rhinitis and where that stands these days? Thanks.
Peter K. Miller -- Chief Executive Officer
Keith, I'll pass the first one to you.
Keith Goldan -- Chief Financial Officer
Yeah. David, thanks for your question. So the the longer term average net revenue per script guidance, we actually never gave guidance, when we were referring to the $200 to $250 range in the past, we were using that as an example in our TAM analysis, when we're building up the the total addressable market and that was based on some other pricing in the market. But, you know, as you -- as we've reported, we've on a quarterly basis exceeded the $200 mark, as we did in 4Q last year when I think we were at $214 average net revenue per TRx.
So, you know, we're not -- we're not giving guidance pass this year. We've -- we're affirming the comfort with the range that we've given $185 to $205. For the first half of the year, we're already within that range at $189. So a very nice increase up to $197. Again, approaching that $200 mark in 2Q. The longer term view is really going to be impacted largely by our contracting strategy and how that dovetails along with our copay affordability program, which works in conjunction with our contracting strategy to make the drug affordable to the patients.
Peter K. Miller -- Chief Executive Officer
Keith, I think that's right on. And the other thing, David, you know, is that because we still have room to grow in our percent of prescriptions that are covered. And we do have line of sight to continue to increase the percent of prescriptions that are covered. That's a potential upside. And as our business shifts more and more to refill, that's also potential on the favorability side. But I think Keith is right to point out, there is real pressure obviously on the payer side, on the contracting side. We're very -- we feel very good about our current position. But as you look forward, there's probably going to continue to be pressure across the board, not just with us, but all pharmaceutical -- all pharmaceutical companies. Second question, Tom. I'll pass to you.
Tom Gibbs -- Chief Commercial Officer
Thanks for the question, David. As you know, our promotional efforts are focused on educating HCPs on the utility of XHANCE in treating nasal polyps. However, physicians can prescribe medications outside of indication based upon their clinical expertise. The data that I will share with you is based upon patient claims data. These data suggest up just under 52% of all prescriptions for XHANCE are written under the XHANCE or I'm sorry -- the chronic sinusitis umbrella, about half in chronic sinusitis, about half in nasal polyps and all other represent about 48% and the majority of those prescriptions are for allergic rhinitis which is just under 25%.
David Amsellem -- Piper Jaffray & Co. -- Analyst
Okay, that's helpful. Thanks.
Operator
Thank you. Our next question comes from David Steinberg with Jefferies. Your line is now open.
David Steinberg -- Jefferies -- Analyst
Thanks. Good afternoon. A couple of questions. First, I know you initiated the seven-day starter packs recently. Any color from the field on sort of what percent, you know, what the fill rate is, how many people have actually started on the starter packs, you know, converted to pay scripts?
And then secondly, just back on ASPs, it looks like you put in a 5% price increase on July 1st. So, just curious in terms of the guidance for the year, should gross to nets might worse a little bit or could you be -- given the price increase and the $20 jump from Q1 to Q2, I assume you be at the upper end of the range or could you even top that the $205 top of the range for pricing this year? Thanks.
Peter K. Miller -- Chief Executive Officer
Tom. I'll let you handle the first one.
Tom Gibbs -- Chief Commercial Officer
Sure. As you know, our territory managers began distributing the seven-day samples back in May. The early feedback from the territory managers are physicians are very excited to have this tool available to them to help them assess the efficacy of XHANCE for their patients. We're pleased with the preliminary qualitative and quantitative analysis that we've done to date, but it's really a bit too early to do a true promotional response analysis on the utility of the tool.
Peter K. Miller -- Chief Executive Officer
David, simply I will say is, we're distributing a lot more samples than we were in 4Q and 1Q.
Tom Gibbs -- Chief Commercial Officer
Yeah, just just to be more specific on that, if you look at the number of -- samples in Q1 were just about 13,000 and Q2 was just over 21,000.
Peter K. Miller -- Chief Executive Officer
Keith, I'll pass the second one to you on ASP.
Keith Goldan -- Chief Financial Officer
Yeah, David, the guidance that we give with respect to average net revenue per prescription is given with the knowledge that we affected the price increase as of July 1, don't forget the -- a lot of that increase doesn't come to the company and the average net revenue per prescription that report takes into account all the gross to net deductions, including distribution service fee payments to the wholesalers, contract rebates that we pay to the PBMs and payers and copay affordability. Those are the three largest, but the guidance fully factors in the price increase.
David Steinberg -- Jefferies -- Analyst
Okay, just two quick follow-ups. So when you initially launched the product, I believe about 50% of the scripts went through specialty pharmacy. And then throughout the line, you can see, you know, there have been some big weekly jumps in reported, you know, IQVIA data, but still some is not going through retail pharmacy. Can you give us up to date ratio of retail scripts versus specialty pharmacy scripts?
And then the second question is just on business development. You know, if the CRS studies read out, you have another indication in a couple of years, but you still only have one products in the bag. And I know the company has limited resources, but are you actually looking at any BD opportunities to in-license or purchase another asset for your sales reps to carry in the bag?
Peter K. Miller -- Chief Executive Officer
Keith, I'll let you handle first one. I'll take the second one.
Keith Goldan -- Chief Financial Officer
Yeah. David, thanks for that question. It's good to get everybody aligned. So currently we believe that IQVIA which is the data provider that we use primarily is picking up approximately 85% to 90% of the prescription volume inclusive of retail and those specialty pharmacies that are in our -- that participate in our preferred pharmacy network. I would say -- I would urge you to use caution in looking at any single week, sometimes when we look at that data, because we have more transparency, more visibility, because we get direct reporting from our specialty pharma partners, we've seen that dip below that 85% mark , again on a week -- week by week basis, but over time, we believe that picking up 85% to 90% of prescription volume.
Peter K. Miller -- Chief Executive Officer
Yeah, David, I think I would add that IQVIA obviously there's a separate factor of the percent of businesses in retail versus our PPN network. And it's the same number obviously a different measure, but about 85% to 90% of our current prescriptions are going through our PPN network. We happen to think that's an advantage because we get a higher first fill rate than you see at retail. We also get a higher refill rate.
David Steinberg -- Jefferies -- Analyst
(Speech Overlap) and the second question -- business development question?
Peter K. Miller -- Chief Executive Officer
Actually, by the way, David, I apologize, I misspoke there 75% to 80%.
Keith Goldan -- Chief Financial Officer
75% to 80% of our prescription volume is flowing through our PPN.
David Steinberg -- Jefferies -- Analyst
And just on the business development question?
Peter K. Miller -- Chief Executive Officer
Yeah on BD, David. You know, as we've said from the start, our ambition is to build a leading E&T analogy specialty company. And you obviously can't do that with just one product. For now, our focus is on ensuring that we build XHANCE. So in the near term, that's our focus. Having said that, we are actively looking at potential products we could bring in the bag and, you know, I'll just stop there.
Operator
Thank you. And our next question comes from Brandon Folkes with Cantor Fitzgerald. Your line is now open.
Brandon Folkes -- Cantor Fitzgerald -- Analyst
Hi. Thanks for taking my questions. Firstly, maybe have you started to engage with payers for 2020 as yet? With 75% covered lives at the moment, should we expect this to be a moving event over -- incremental information?
Peter K. Miller -- Chief Executive Officer
Tom, I'll let you take that one.
Tom Gibbs -- Chief Commercial Officer
Sure. Thanks, Brandon. We continue to engage payers and try to drive our what we call hassle free or low hassle market access through the commercial segment. We're working in two different areas. The first on the commercial side we continue to drive and expect to increase our market access as we move into 2020. We've had -- we just signed, as we talked about, one of the largest health plans in the United States this past month. And then we've -- we continue to engage other payers as well. Also on the Medicare Part D-front, as you know, these are annual cycles. We're engaged in the Medicare Part D cycle and we expect to increase our access in 2020 there as well.
Brandon Folkes -- Cantor Fitzgerald -- Analyst
Great, thanks. Maybe one follow-up on the reduction in OpEx guidance, given that you are in a launch and you will start DTC campaign, can you give us some color in terms of where you are finding those savings and how much leverage there may be in the business model? Thank you.
Peter K. Miller -- Chief Executive Officer
Keith, I'll let you take that Keith.
Keith Goldan -- Chief Financial Officer
So thanks, Brandon. So I can tell you that the reduction in the OpEx guidance was not driven by a need to find savings, especially in our commercial organization. We, as you said, we're in a launch and we feel we're investing appropriately. The savings were -- I would characterize them as more driven by efficiencies within the business. And our focus on being judicious with our expenditures. With respect to leverage, I think we do, I think the BD question that came earlier was one about leverage. We have capacity in the field force, but today, we think that capacity is best used to focus on XHANCE because that's what's going to drive value in the near to mid-term. Obviously looking out longer, as Peter commented, we believe that there is the opportunity to leverage the asset, the commercial infrastructure that we've built and get more juice out of that asset.
Peter K. Miller -- Chief Executive Officer
I'd add to that. Keith, also just General SG&A that we've built a Company from the areas outside of commercial that is very leveragable as well. So, it's obviously something that is part of our strategy and it's going to become a focus once we are absolutely certain that we have XHANCE where it needs to be. And we feel very good about the business based on, you know, growth in the second quarter and growth in July.
Brandon Folkes -- Cantor Fitzgerald -- Analyst
Great. Thank you very much.
Operator
Thank you. And our next question comes from Gary Nachman with BMO Capital Markets. Your line is now open.
Gary Nachman -- BMO Capital Markets -- Analyst
Hi, guys, back on the net revenue per Rx, any reason to think it shouldn't continue to increase in the second half versus the third quarter, especially if refills accelerate the way you're talking about, Peter? And then maybe more broadly, just what are some of your key assumptions embedded in the full-year sales guidance? How much more share capture are you assuming? What's the biggest drivers behind that range to give us comfort that you could hit that ramp in the second half?
Peter K. Miller -- Chief Executive Officer
Keith, I'll let you tackle the first one.
Keith Goldan -- Chief Financial Officer
Yeah, Gary, unfortunately, we're not going to be any more specific other than kind of affirming our confidence in the range. You know, there's certainly some tailwinds, as Peter mentioned, like the proportionality of refills. You know, some of it depends on our contracting strategy. So, we're just not going to comment further than that, given you -- given this audience confidence that we're going to be landing in that range for the full year.
Peter K. Miller -- Chief Executive Officer
And Gary, relative the full year net revenue, I know, you know as well, we really look hard at the data and the facts supporting it. And I'm going to state what's obvious. But, you know, the midpoint of the range is roughly a doubling of our first half of the year. We achieved $10.7 million of revenue for the first half of the year. You go to the midpoint in the range, $31.5 million, that's about a doubling and when we sort of look at the underlying dynamics, you know, as Tom mentioned earlier, we sort of split the analysis into our legacy territories and then our new territories, and we feel really good about the trends in our legacy territories. I mean, they are -- we just see growth virtually across the board. And Tom mentioned that we feel great about our sales team.
The one that's, you know, a little bit harder to predict is going to be when the new territories really come on board and start contributing. We obviously have as an analog last year, but, you know, frankly, the patient affordability was a little bit different, a little bit harder to predict on that side. But those are the big factors. You know, we have -- we really feel good about having our arms around average net revenue per prescription. So it's going to come down to volume and we're feeling really good about the business right now.
Gary Nachman -- BMO Capital Markets -- Analyst
Okay. And then, Peter, what else could you do to kick-start further prescriptions demand? I know you have a lot of initiatives in place, but would you consider some type of creative commercial partnership maybe before having the CS indication in hand? And maybe, Ramy, could just give a quick update, just, you know, how you see those trials progressing and what's a likely time frame for when you could have the data on that?
Peter K. Miller -- Chief Executive Officer
Yeah. I got to state the obvious, Gary, on the first question, which is there are interesting partnering opportunities in the ENT allergy space for acceleration and those are certainly things that we are looking at at this point in time. And you know, it's -- our business is all about how do we accelerate growth in the near term on XHANCE. And then how do we build sort of a company an ENT company in the longer term, which obviously will be bringing some new products in. So, you know, obviously without -- I want to be careful disclosing anything, but, you know, we are looking at ways to accelerate beyond just organic growth. With that, Ramy, I'll let you tackle the second question.
Ramy A. Mahmoud -- President and Chief Operating Officer
Hi, Gary, thanks. I just want to remind you that we started the first chronic sinusitis trial in the fourth quarter of last year, 2018, and the second trial, just this last quarter, we're reporting on second quarter of 2019, and one of the first tasks in getting the trials going is really to get the sites up and running, most of US sites are onboard now, but a lot of our global sites have a longer time lag on them because of the necessary approvals in other countries to be able to initiate the trials. So we're still very active in trying to get a lot of those global sites up and running. It's hard for us to give confident estimates about when we're going to see the final data from these trials because of unknowns about the enrollment rate and some other factors. These trials are sort of first in class. This indication has never been achieved before. It's not a territory that's well understood based on precedent. But we do expect to understand it better after we get more of our sort of heterogeneous sites around the world up and running later this year.
Gary Nachman -- BMO Capital Markets -- Analyst
Okay. And one last quick one. Peter, are you going to have the post hoc analysis and you're going to try and get it in a publication maybe sometime in the near future? How are you going to be able to go out and market that?
Peter K. Miller -- Chief Executive Officer
Yes, absolutely. Gary and I, you know, we are planning to make sure that we take all the areas that are open to us to make sure that physicians become aware and payers, you know, it has compelling data on both sides.
Gary Nachman -- BMO Capital Markets -- Analyst
Okay. All right. Thanks.
Peter K. Miller -- Chief Executive Officer
Publications actually part of it.
Gary Nachman -- BMO Capital Markets -- Analyst
Yeah. Okay.
