Jan Mikkelsen

Thanks, Scott, and good afternoon.

We continued to make progress towards our goal to create sustainable growth by building a diversified pipeline of three independent product opportunities in rare disease endocrinology.

Let me review our recent progress. We are reporting today, the expected and predicted Phase 1 clinical results for the third rare disease endocrinology product candidate in a row, TransCon CNP. Our clinical with us to-date support our target product profile and confirm findings from our preclinical research. Our goal is to provide continuous and therapeutic levels of CNP for [20] hours a day, seven days a week without increased cardiovascular risk and without weekly administration. We have now clinical data that reinforces our target product profile.

We expanded our global footprint through the formation of VISEN Pharmaceuticals in Greater China. Earlier this month, we announced the VISEN partnership which provides us with a compelling upside opportunity in China. VISEN also expands the potential reach of our rare disease clinical programs into China, which has a larger population than the United States and Europe combined. And at the end of the third quarter, we completed recruitment in our fliGHt trial, which brings us up to more than 300 pediatric subjects enrolled in our TransCon Growth Hormone Phase 3 program. This was another key step to advance our long-acting growth hormone therapy towards patient as we await readout of the Phase 3 heiGHt trial in the first quarter of 2019.

My reflections today will focus on TransCon CNP. TransCon CNP is now the third rare disease endocrinology product candidate where we have created a potential best in class therapy. The clinical results presented to-date also demonstrate once again and excellent translation from preclinical to clinical data, and the broad applicability of the TransCon technology.

As you may know, the fibroblast growth receptor 3 is a negative regulator of bone growth, as activation of the receptor signaling pathways in the growth plate inhabits chondrocytes, proliferation and differentiation. Achondroplasia is caused by a continuous over activation of the FGFR3 signaling pathway by dominant mutation in the receptor. This continuous over activation severely limits bone growth.

We believe to provide a highly effective treatment for achondroplasia, the continuous over activation of the receptor signaling pathway must be counterbalanced 24 hours a day seven days a week. CNP and its receptor NPR-B are well-established as positive regulator of growth. CNP finds to its receptor in the growth plate and counterbalance the signaling pathway of FGFR3. Increased CNP levels are closely related to linear growth in healthy children at all ages.

In achondroplasia, CNP counterbalance, the constant over active signaling pathways caused by receptor mutation. Therefore, continuous exposure to CNP at effective levels should result in normalization of the balance between the activity of the FGR3 [ph] and the CNP pathways, a balance that is essential for normal bone growth.

The biology of CNP has been known for many years but the use of CNP as a pharmaceutical product has been limited by shortcomings of the native CNP peptide. These include firstly, a short duration of action. Native CNP has a half life of only two to three minutes in human, making it impractical to maintain constant dark exposure from one administration to the next.

Secondly, degradation of the native CNP in the subcutaneous tissue and blood compartment by neutral endopeptidase requires IV administrations in humans to maintain an effective CNP level. Lastly, high systemic concentration of CNP causes vasodilation, which can trigger adverse cardiovascular effects. Therefore, development -- developing a safe and effective CNP therapy is difficult, but a challenge that our TransCon technology is uniquely designed to overcome.

Today we are reporting top-line clinical data from our TransCon CNP program. Let me review these findings. First, we have demonstrated in the clinic that a single dose of TransCon CNP provides continuous CNP exposure or the entire week with a half life of around 90 hours, an improvement of around 2,000 times the half life of native CNP.

The continuous release of CNP from TransCon CNP also avoids [ph] high peak levels that trigger adverse cardiovascular effect. TransCon CNP PK profile also support a once weekly administration. The PK profiles of different doses of TransCon CNP show that it has dose-related increase in CNP exposure and low intersubject variability. These data suggest the ability to apply [ph] TransCon to the retarget CNP levels 24/7. At the target CNP levels, we believe we can balance the CNP FGFR3 pathways and normalize growth in achondroplasia and other diseases that CNP mainly may treat.

Turning to safety findings. Our results in healthy adult subjects who received single injection across five different dose cohorts of TransCon CNP show no impact on mean resting blood pressure and heart rate compared to pre-dose levels, even at the highest tested dose of 150 micrograms per kilo. These findings are consistent with our preclinical studies and publications with continuous IV infusion of native CNP in healthy subjects.

Finally, our preliminary safety data suggests an attractive safety profile with no severe or serious drug related adverse events and well tolerated injection site reaction. In fact, orthostatic changes appear unrelated to the study drug and consistent between placebo and treated cohorts.

There is currently no FDA approved medical treatment for achondroplasia. Our goal is to develop TransCon CNP as a new therapeutic option that has a significant impact on patients’ life, not only affecting height but potentially addressing the many comorbidities associated with this disease.

TransCon CNP has the potential to deliver a continuous exposure of CNP at therapeutic levels for 24 hours a day seven days a week without adverse cardiovascular effects. Most importantly, it provides patients with achondroplasia and other FGFR [ph] receptor related diseases, the potential for an effective and safe therapeutic option.

To-date, daily growth hormone therapy is the cornerstone treatment for many growth disorders including growth hormone deficiency, idiopathic short stature, Turner syndrome and others. With today's data, we believe Ascendis Pharma has the potential to bring both once weekly growth hormone and once weekly CNP therapy to patients. Given the promise of these two product opportunities, Ascendis is in an unique position to have a potential to treat a broad spectrum of growth disorders. Some disorders may be optimally treated with TransCon Growth Hormone and others with TransCon CNP; indeed some growth disorders may potentially be treated optimally with a combination of both TransCon Growth Hormone and TransCon CNP. And we are intrigued to report this opportunity and position Ascendis on the frontier of growth biology. Today’s data is an important step forward for TransCon portfolio.

Now, I turn it over to Jonathan for an update on the clinical programs.

Dr. Jonathan Leff

Thanks, Jan.

I am pleased to provide an update today on recent pipeline developments, including additional details on our TransCon CNP program. First, I will share some highlights for our other two clinical candidates TransCon Growth Hormone and TransCon PTH.

We remain on track to report top-line results for our Phase 3 heiGHt trial in the first quarter of 2019. As a reminder, heiGHt is a randomized, open-label, active-controlled trial comparing once weekly TransCon Growth Hormone to daily Genotropin in treatment naïve pediatric subjects with growth hormone deficiency. The primary endpoint is annualized height velocity at 52 weeks. A non-inferiority analysis will compare both treatment groups. We enrolled 161 subjects ranging in age from 3 to 12. We believe the strong statistical power of heiGHt bodes well for the potential of TransCon Growth Hormone.

We also recently passed our third Data Safety and Monitoring Board review for heiGHt during which independent experts evaluated the safety data and recommended the trial continue as planned. We are pleased with the safety profile for TransCon Growth Hormone as our review of aggregate data from heiGHt continue to be consistent with that of published literature and experience with daily growth hormone therapies.

Our second clinical trial for TransCon Growth Hormone, the fliGHt or were SWITCH trial also completed enrollment at the end of the third quarter. The total of 146 subjects were enrolled, which means we now have more than 300 pediatric subjects enrolled in our Phase 3 clinical program. The combined safety data will form an important component of our filing package and achieves the safety database as agreed with regulatory authorities in Europe and the U.S.

To review, the fliGHt trial is evaluating safety in subjects who switched from Daily Growth Hormone therapy to weekly trends on TransCon Growth Hormone with the follow-up of 6 months. The result of this trial will not only strengthen the safety experience for TransCon Growth Hormone, but are also expected to guide physicians on switching patients from daily to weekly therapy.

Importantly, fliGHt includes some that were below 3 years of age. This will provide important information on utilization of TransCon Growth Hormone in subjects younger than those enrolled in the heiGHt trial.

Finally, enrollment continues in the third component of our Phase 3 program, the enliGHten trial, an open-label long-term extension that includes subjects who participated in either the heiGHt or fliGHt trials. To-date, about 165 subjects have been rolled as subjects complete the heiGHt and fliGHt trials.

While we proceed with our clinical programs, our underlying focus remains on patients. We believe a once weekly growth hormone therapy could overcome a key challenge that hinders children with growth hormone efficiency, the continued struggle of adherence with daily therapies. Missed doses not only impact height, but can also adversely affect bone, muscle, heart and brain development. With the potential to provide the same efficacy, safety and tolerability as daily growth hormone, TransCon Growth Hormone is designed to overcome this barrier and have a positive impact on patients’ lives.

Turning now to our second pipeline candidate, TransCon PTH. We are making good progress preparing to initiate a randomized placebo controlled Phase 2 trial in the first quarter of 2019. As a reminder, TransCon PTH is a long-acting pro drug of parathyroid hormone or PTH. It is in development to treat hypoparathyroidism, a rare endocrine disorder characterized by insufficient levels of PTH, resulting in low calcium and elevated phosphate levels in the blood. Maintaining continuous and sustained levels of PTH in the physiological range has been shown to not only raise serum calcium levels but also normalize the processes related to bone turnover and kidney function.

We expect the Phase 2 trial to enroll approximately 40 subjects in North America and Europe. The primary endpoint will be a composite endpoint, representing control of serum and urinary calcium levels, as well as reduction in calcium and vitamin D requirements. In this trial, TransCon PTH will be administered via an injection pen.

As mentioned previously, the trial will explore a titration schedule, designed to evaluate the ability to completely remove standard of care with activated vitamin D and calcium supplementation. The trial duration will be four weeks after which subjects may enter long-term extension trial.

Finally, let me add some comments on our third pipeline candidate, TransCon CNP, including details related to the preliminary data presented today and shown in the deck posted on our website.

The Phase 1 trial was a double-blind, randomized, placebo-controlled trial, evaluating the safety, tolerability and pharmacokinetics of TransCon CNP in healthy adult subjects. In this trial, the total of 45 subjects were enrolled. The trial tested 5 doses sequentially, 3, 10, 25, 75, and 150 micrograms per kilogram. Up to 10 subjects were randomized to receive TransCon CNP or placebo in a 4 to 1 ratio. After each dose level was completed, the DSMB was convened to review the blinded data and approve escalation for the next higher dose. The data were unblinded after each assessment.

As Jan described, the preliminary data from this trial support our moving ahead with plans to final the U.S. IND in mid 2019, and initiate a Phase 2 trial of TransCon CNP in subjects with achondroplasia soon thereafter.

They also support our desired profile for TransCon CNP. In addition, we plan to initiate the ACHIEVE trial, our natural history study in achondroplasia by the end of this year. We believe the ACHIEVE trial will provide important observational insights into the experience of children living with achondroplasia, further informing our clinical program going forward.

We are all acutely aware of the need for a safe and effective therapeutic option for achondroplasia. It is the most common form of dwarfism, occurring in about 1 in 10,000 to 30,000 newborns or approximately 250,000 worldwide. Current treatments and development may increase heights, but for patients, the associated comorbidities are much more devastating. These include spinal stenosis and narrowing of the spinal canal that can compress the upper part of the spinal cord, hydrocephalus, a buildup of fluid in the brain and sleep apnea among many others.

With the potential of TransCon CNP to deliver continuous levels of CNP over one week, our hope is to develop a treatment option that improves many aspects of patients’ lives, well beyond just height.

All three of our pipeline programs have now been clinically validated. And we're exploring opportunities to strengthen our global presence and bring our innovative therapies to patients worldwide. Our VISEN partnership enables this for all three of our clinical programs in China. And in parallel, we continue to pursue additional opportunities in other parts of Asia with our other programs.

Throughout the year, we've made great strides with our three potential therapies for rare endocrine diseases. Looking ahead to 2019, we are enthusiastic about reporting pivotal data for our TransCon Growth Hormone program and ramping up clinical activities for our other two programs in hypoparathyroidism and achondroplasia. Our pipeline now includes three endocrinology programs with strong target product profiles, all three supported by clinical data.

In closing, I would like to thank our investigators and patient communities for their contributions in supporting our efforts to develop new and differentiated therapies to treat rare and endocrine diseases.

Now, Scott will provide a financial update.

Scott Smith

Thank you, Jonathan.

Turning to our financial results for the three months ended September 30, 2018. Let me review some highlights.

For the third quarter, we reported a net loss of €34 million or €0.81 per basic and diluted share compared to a net loss of €33.9 million or €1.04 per basic and diluted share during the same period in 2017.

Third quarter 2018 results reflect financial income of €4.3 million due to foreign currency exchange rate fluctuations of our cash holdings. Research and development costs for the third quarter were €31.5 million compared to €29.1 million during the same period in 2017. The overall higher costs were primarily attributable to an overall increase in R&D activities across all programs including an increase in personnel costs due to a higher number of employees in R&D functions and general increases due to growth in headcount and activities including an increase in facility, IT and patent costs allocated to R&D.

For TransCon Growth Hormone, external development costs were lower due to lower costs associated with manufacturing TransCon Growth Hormones for use in clinical trials, partially offset by an increase in costs related to the continued execution and expansion of our Phase 3 clinical program and the ongoing development of the auto injector as well as the preparation and manufacturing of TransCon Growth Hormone validation batches.

For TransCon PTH, higher external development costs were driven by costs related to Phase 2 enabling activities, including manufacturing of TransCon PTH and device development, partially offset by lower preclinical costs and lower clinical trial costs due to completion of our Phase 1 trial. And for TransCon CNP external, development costs were comparable to the same period in 2017, reflecting higher costs associated with execution of the Phase 1 trial and ongoing Phase 2-enabling activities, offset by lower preclinical trials.

General and administrative expenses for the third quarter of 2018 were €6.8 million compared to €2.8 million during the third quarter of 2017. These higher costs primarily reflect an increase in administrative personnel, including increased site costs, as well as the initial cost of building out a commercial organization. We ended the third quarter with cash and cash equivalents of €310.3 million and 42,032,522 ordinary shares outstanding.

We expect costs to continue to increase as we advance our internal pipeline programs and further invest in the TransCon technology. Costs are expected to include for TransCon Growth Hormone costs associated with our Phase 3 program, including manufacturing of clinical supply and validation batches, as well as continued development and manufacturing of the auto injector used for administration; for TransCon PTH, ongoing IND-enabling activities, including non-clinical tox, manufacturing of clinical supply and validation batches, regulatory and device development activities, as well as preparation for and execution of our Phase 2 clinical trial; for TransCon CNP costs associated with initiation of the ACHIEVE natural history trial and activities related to Phase 2 including non-clinical tox manufacturing; for the development of commercial capabilities and related activities; and finally, outside of our rare endocrine disease product candidates, costs associated with further developing the TransCon technology including potentially entering into new therapeutic areas.

We plan to continue to create long-term sustainable growth as we acquire innovative TransCon technology and product development algorithm in other therapeutic areas and expand on the global basis. To that end, subsequent to the completion of the third quarter, we announced the formation of VISEN Pharmaceuticals with an investor syndicate led by Vivo Capital to develop, manufacture and commercialize our endocrinology rare disease therapies in Greater China. With VISEN, Ascendis found a partner with a great management team dedicated to accelerating development of our rare endocrine disease product candidates in the world’s second largest pharmaceutical market.

Our equity ownership will be carried on the balance sheet under the equity method of accounting, adjusted for our share of the profit or loss of VISEN. Development of the rare endocrine disease product candidates will be governed by agreements, including a research and technical development plan. VISEN has agreed to reimburse Ascendis for services delivered under the plan. Ascendis will also provide product supply to VISEN for use in conducting clinical trials in Greater China, pursuant to separate clinical supply agreements for which VISEN will also reimburse Ascendis.

Operator, we are now ready to take questions.

Question-and-Answer Session

Operator

Thank you, sir. [Operator Instructions] And our first question will come from the line of Michelle Gilson with Canaccord Genuity. Your line is now open.

Michelle Gilson

Hi. Congratulations on the data. I'm just wondering, can you talk a little bit about the path forward for TransCon CNP? And what is the age range [ph] of patients that you plan to enroll in your Phase 2 study? And then, you talk a lot about correcting comorbidities, and can you talk a little bit about how young that you think that patients need to be treated in order to correct for those comorbidities? And then, I have a follow-up as well.

Jan Mikkelsen

It's going back to our vision about what we really want to achieve with TransCon CNP. Our hope with TransCon CNP is really not only addressing height but really can address the comorbidity of this disease. And your 100% right, to address these comorbidities, we strongly believe that we need to go down to basic newborn children. So, we can ensure they get at balanced growth of bones, so that can develop them in a more normal manner. Because sometime you potentially first see the physical symptoms later on in life but potential is already pretty turned in the beginning of the early part of the development. So, therefore, we are not spending years on making heiGHt trial. Our vision is to move as fast as possible through and stage process that we will discuss with the regulatory agencies and ensure, we can get the right pathway forward, so we can get this treatment as fast as possible down to newborn children. This is basic our overall vision for that. More concrete question, I'm quite sure Jonathan can follow up with.

Dr. Jonathan Leff

Yes. I don't have a whole lot to add. I mean, we'll likely start because of our very clean safety profile in children as young as two and above, and then move quickly as quickly as we can, after discussions with regulatory authorities to newborns. So, our clear goal is to get to the newborn children, those are the ones with the greatest need, where the impact can be the greatest. So, we look forward to those discussions with regulatory authorities, based on our safety profile that we've developed in the Phase 1 study.

Michelle Gilson

Okay. And then, when you think about dose in that Phase 2, when you're choosing a Phase 2 dose range or dose, are you looking at trends that you see in nature with CNP within the population or data from others in space or what you're seeing in animals? And then, are you thinking about it about looking at based on concentration or titrating that dose?

Jan Mikkelsen

That is an excellent question. And what we have done, we have done an integrated analysis where we are integrating preclinical finding in models of achondroplasia and other related diseases, what we have seen of what CNP can promote in overgrowth in humans, and also, the literature, all the data that is related to CNP and the prototype of CNP in patients with achondroplasia.

I can give you a little bit of flavor on this last integrated analysis. For example when we look on continuous exposure on preclinical models, there’s a clear effect on dose and the effective dose is down for 2 to 15 picomolars. So, we down in a range of very, very low dose of CNP, if it's just being provided on a continuous manner.

If you go to overgrowth in humans; there was a girl with overgrowth, meaning that you grow up to 97% of the percentile. And this person only had two fold higher concentrations than normal people of CNP. And when we go to achondroplasia children, there’s a really nice correlation between height velocity and the propeptide of CNP. And always what we are seeing of data is that the propeptide of CNP is already correlating to the CNP. And what you see with the propeptide is that 2 to 3-fold increase in this pro type can promote or correlate up to -- growth up to 8 to 10 centimeters in achondroplasia.

So, this is why we someway know exactly what the dose and potential of a dose need to be individualized to each single patient. But we believe a range between 4 to 30 picomole is where we expect, and perhaps 30 is just too high. But, this is the level where we exactly believe where we will be in our -- what we call, our target therapeutic range.

Dr. Jonathan Leff

And just to add, I think it's very unlikely, there'll be a single target level that we want to achieve in all subjects. I think it's very likely there'll be a distribution of response. And as you suggested, it may well be the titration individually by patient is the way to go here. So, we look forward to learning a whole lot in our Phase 2 study where we will explore different doses and begin to correlate the growth that we see and other beneficial effects versus the target levels that we see in their blood.

Operator

Thank you. Our next question will come from Jim Birchenough with Wells Fargo Securities. Your line is now open.

Jim Birchenough

Hi, guys. Thanks for taking the question. Congrats on all the progress. Just a question on each program. So, for TransCon Growth Hormone, the patients that have gone into open-label extension, what proportion of available patients does that represent? On the PTH program, I'm interested in, if you've got more detail on what defines a responder. It seems like you're contemplating serum calcium, urine calcium, use of Vitamin D in calcium. Just understanding more explicitly, what a responder might be. And then, finally, on CNP, do you think the natural history study could provide a control arm ultimately for registration of the product? And when do you think you'll get better visibility from FDA on what an approvable profile would represent? Thanks.

Dr. Jonathan Leff

Okay. Thanks, Jim for all the questions. And starting with growth hormone. As I said, we have 165 subjects in the enliGHten trial. So, that's over half of all the subjects are now already in enliGHten. So, we're really thrilled with the execution of the trial. It's moving along as expected, and we're just accumulating more and more data every week. In terms of PTH, our primary endpoint will be a composite endpoint, requiring normalization of serum calcium, importantly normalization of urinary calcium and a reduction in calcium and vitamin D, which may be quite extensive in some subjects. So, in order to achieve the primary endpoint, you need to achieve all 3 components of the composite. And that will be in both our Phase 2 and our subsequent Phase 3 studies.

In terms of CNP, the natural history study will be beneficial in a lot of ways. It will conform a controlled group. There’s also published literature and norms they can represent a controlled group. It’s a little premature to talk about the actual Phase 2 and Phase 3 study designs; we’ve not finalized those yet. But certainly, the natural history study will form an important component to the analysis of those studies.

Jim Birchenough

And Jonathan, just to follow-up on the question, on TransCon Growth Hormone. Just on the 165 patients that have gone into enliGHten, what proportion of eligible patients does that represent? It sounds like it represents 50% of total, but patients may not yet be eligible to go into the open label extension. So, what proportion of eligible patients does that represent? And what reasons are you seeing for patients not going to open-label expansion, if there are many?

Dr. Jonathan Leff

Sure. So, that represents the vast majority of patients who are capable. So, they were literally one, maybe two, who for logistical reasons, chose not to answer enliGHten but they were not due to any adverse experience. One patient moved from one-site away from the site for example. So, the vast majority of patients have very willingly joined the enliGHten trial.

Operator

Thank you. [Operator Instructions] And our next question will come from the line of Jessica Fye with JP Morgan. Your line is now open.

Jessica Fye

I wanted to follow-up on one of the earlier questions. I’m curious, as you think about discussing Phase 2 with the FDA for TransCon CNP, what you want to measure and what you might kind of ask the FDA for feedback on in terms of what you measure in that study, I guess outside of just growth?

Jan Mikkelsen

I think, this is really a great question. And this is actually where we’re spending a lot of thinking about, what is the optimal endpoint that’s really affecting comorbidities. And we also need to be practical. It needs to be something we can measure pretty fast. We don’t want to wait 3, 4, 5 years. So, we basically have generated an integrated list of opportunities. We are evaluating all this list of opportunities to prepare with the key opinion leaders, getting a lot of feedback with them. We also will discuss that with the regulatory agencies. But, the obvious one from the list is someway where we really can address something that is extremely meaningful for the patient. It can be something like severe sleep apnea, it can be way to look on spinal stenosis, it can be other element. This is the thinking about few, we will also measure height because there’s also some way to test the efficacy of the compound. But, when we saw these results, it was basically the best we ever had hoped for. And when we saw that, we really for the first time got a strong belief that we have an opportunity to provide a highly effective treatment. And we know from preclinical models, we can basically reverse the phenotypes and I think that is what we want to receive.

Jessica Fye

Okay. And I guess, I'm kind of asking because, if you're -- if you think titration to maybe -- given pre-CNP level might be how the product is used, I'm curious what you might measure to establish an association that different levels have different effects on whatever those metrics are?

Jan Mikkelsen

You’re 100% right. This is what we call the feasibility of conducting the trials and often that we are addressing a lot of respect and it could be specific biomarkers that's reflecting growth velocity or effect on growth rate. It could also be different kinds of imaging system where we are looking about how can we see the development of the growth plate. So that is what we are integrating into our decision how really to bring forward this product as fast as possible. And really address some of the more morbidities.

Jessica Fye

Okay. And I just want to reask my question from last quarter. Can you just provide the latest status of where you stand on manufacturing for TransCon GH and those validation batches?

Jan Mikkelsen

It's going forward as we have hoped, according to our plans. No deviation, no change. So, we are executing as we had planned for. And every month, we’re executing on our plan, are getting more and more happy.

Operator

Thank you. And our next question will come from the line of Liana Moussatos with Wedbush Securities Your line is now open.

Liana Moussatos

Thank you for taking my question. Will VISEN pharma have the same pipeline as Ascendis? What is the cash runway from the €310 million? And did the third DSMB meeting have a futility analysis?

Jan Mikkelsen

So, I will take first part of the first question. No, VISEN Pharmaceuticals will not have the same pipeline as Ascendis Pharma; we are providing, to VISEN Pharmaceuticals; and three, define product opportunities in the era of TransCon Growth Hormone, TransCon PTH and TransCon CNP and we have provided them an option for negotiation and looking on other endocrinology products, the potential was developed. So there is no overlap between the two pipeline. Scott would take the second part of that question, and then Jonathan will take the last one.

Scott Smith

So, we had about €310 million as of the quarter end. As you know, we don't give cash burn guidance. But, if you pro forma cash from the beginning of the year, we had about 300 -- little over €390 million. So, if you do the math, that's €80 million or so for the nine months. Jonathan?

Dr. Jonathan Leff

There is no futility analysis in the DSMB meeting.

Liana Moussatos

All right. But, you said, Scott that costs are going to increase from the €80 million over the nine months. So, that's a base. And what are you thinking over the next 12 months, increase over that base?

Scott Smith

I mean, we haven't changed our policy, we still don't give official forward-looking guidance. But you're right, we would expect costs to increase in those different categories overall, but specifically because of those categories. But we have -- I mean, we have plenty of cash going forward, if that's the question. I mean there's no liquidity concerns.

Operator

Thank you. Our next question will come from Adam Walsh with Stifel. Your line is now open.

Adam Walsh

Hey, guys. Thanks for taking my questions. I got a couple of quick ones here. The first one is for Jonathan. Obviously, the safety data looks pretty clean here with no serious AEs. I'm just curious to check a safety box here, over the most commonly observed AEs in CNP study, TransCon CNP. And then a second question, in terms of advancing the CNP program next year, can you give us some guess at what the timing would be in terms of trial launch and what they expect the duration of such trial would be. Just trying to figure out when we might see the next data point from the CNP program? Thanks.

Dr. Jonathan Leff

So, in terms of AE, there is really nothing remarkable. I mean, it's headaches, it's just the usual AEs that you see in the clinical trial, back pains, that sort of thing. When you look for what the static blood pressure changes, you can see some of that, even in placebo pre-dose levels, post-dose, so just the normal scattering of AE that you see in trials.

The CNP study, we would initiate it mid next year. So, that will take many, many months. So, we don't even have our timelines for recruitment established yet. So, it certainly would not be in 2019.

So, Adam, I think it's a great question. I think it's a question where we will come clear milestones when we feel confident that we really have been in a sufficient high level discussion with regulatory agents that we feel comfortable with the timeline. So, when we give you a timeline, this is timeline we basically believe we can reach and keep.

Thank you. And our next question will come from the line of Tiago Fauth with Credit Suisse. Your line is now open.

Tiago Fauth

Hey, guys. Thanks for taking the question. So, fliGHt trial I understand that that’s mostly a safety study but should we be looking for anything on the secondaries? And can you perhaps recap the work that you're going to introduce the device into the extension study for GH? Thanks.

Jan Mikkelsen

You're really nailing it down to a great point because I feel when I think of height, this is most important for regulatory approval. But the fliGHt trial is really the most interesting trial related to the commercial opportunities we have with our TransCon Growth Hormone, because we basically will know what is the prescription of the daily growth hormone before they have, meaning is that we get a reality check what do you really prescribe of daily growth hormone before you go out to a TransCon Growth Hormone that will provide much, much higher adherence. And this is why it's so really interesting to get this data, analyze them and we will -- can provide you with guidance about what is really the ratio that will be when you have for example 0.30 milligram on average of a daily growth hormone, do you need to go down to all points to 0.24 or 0.27 or what is the ratio you need to go or 0.20 for having the amount of our TransCon Growth Hormone. Besides that, Jonathan is thrilled to give all the safety data because that is what he has committed himself into, in both Europe and U.S. and this is why he -- so once we get it done, so he can start closing his data bases.

Dr. Jonathan Leff

You’re probably also wondering about height and efficacy data. And we will measure height, of course, in every patient. And I only caution you these patients or subjects who are on daily growth hormone therapies for varying lengths of time, some for a few months, some for a year, some for two years, so, when you do those analyses, it will be compounded in our assessment. So, we will, of course, look at it, we will do our best to carry out real heiGHt data. Jan already mentioned the varying potency of effect of IGF-1 when we switch 0.24 mgs/kg per week.

And in terms of the device, we’re in the second quarter of 2019 beginning to roll the device into our expansion program. So patients won’t come in specifically for that; they’re on a schedule of every three months. So, the next visit that they come in, they will get the device. So, over the course of 2019, we’ll be rolling out the device beginning in the second quarter.

And our next question will come from the line of Joseph Schwartz with Leerink Partners. Your line is now open.

Joseph Schwartz

So, regarding the CNP data first. I was just wondering if you’ve captured any pharmacodynamic biomarkers, which you could present beyond this preliminary data, things like collagen 10 or alkaline phosphatase or anything else, all the complex bone signaling pathways?

Jan Mikkelsen

So, great question. What we’re using here is adult; and because adult we’re using would have close growth basis. So, therefore measuring some of the things that you basically can measure in a pediatric population where the child is still growing, it’s not possible in an adult population. And we had a lot of funny discussion about cyclic GMP. And Jonathan came back to me and saying Jan, if we see cyclic GMP, I would be worried, because then I will actually believe we see dilation.

And definitely, this is really pretty clear, the cyclic GMP in our view the best predictor of vasodilation and cardiovascular risk, because cyclic GMP not likely is coming from the growth place, but highly, highly likely coming from the cardiovascular system where you actually are introducing in vasodilation effect. So, therefore, when you see that with all the CNP product, you see cyclic GMP, I don’t think you can ever reflect that into any kind of effect related to -- effect on both, but it’s mainly effect on how you actual receive cardiovascular risk effect.

Joseph Schwartz

And then, regarding TransCon PTH Natpara was associated or is associated, but it’s -- pivotal trial associated with hypo and hypercalcemia. I was wondering if -- based on your agreement with the updated dose ranging study, how you're ensuring that patients will be titrated accordingly?

Dr. Jonathan Leff

Well, it's pretty straightforward. With a infusing like profile like we see, of course, we're going to measure serum calcium levels very frequently in these subjects. So, we'll be monitoring them very closely. We don't think we will see the hypo or hypercalcemia that Natpara saw, because we think that's very clearly related to the pharmacokinetics of Natpara where you have very high CMAX, and then a very low C trough over the course of the day. Instead, we'll have a steady level over the course of the day, which should make it much easier to monitor the calcium levels and we should see much fewer excursions of serum calcium. So, we’ll essentially just monitor it, and I'm sure FDA will be very comfortable with that approach.

Joseph Schwartz

Okay, great. Thanks for taking my question.

Operator

Thank you. [Operator Instructions] And our next question will come from the line of Jim Birchenough with Wells Fargo Securities. Your line is now open.

Jim Birchenough

Thanks for taking the follow-ups. We get a lot of questions on how to think about the scenarios in the heiGHt trial. So, maybe from a commercial planning perspective, you can give us your thoughts on different outcomes and whether it's just success or failure in non-inferiority or whether you think numerical superiority is important for growth velocity? And then, I've got a follow-up. Thanks.

Jan Mikkelsen

Jim, that is a great question. But, what we did, we tried to derisk everything on a Phase 2 stage. There was where we had the same setup with inclusion, exclusion criteria as we now have in Phase 3. This is where we use the same comparative, actually this is where we have the same clinical endpoint. So, what we did and what we are hopeful we'll see here in our Phase 3 study that we can repeat what we did in our Phase 2 study because that is basic what we are trying to attempt to happen with our Phase 3 study. Main difference, this is one single dose, and it's a 12 months instead of 6 months but the fundamentals are not changed. We are providing the same mode of action as daily growth hormone, and [indiscernible] growth hormone in the same footing, being proven to give optimal efficacy out from daily growth hormone, and that is what we are doing.

So, I think that the question is not some of the speculation, I think the best thing you can do, analyze our Phase 2 data and see how robust they are and how well we can predict. And this is why are we happy to have all this data that have provided us bio stat analysis to really give us confident in the outcome on all heiGHt trial.

Jim Birchenough

That’s helpful, Jan. And then just on CNP, it seems like spinal stenosis contributes a fair amount of morbidity to these patients. And so, do you have a sense from the published literature on how early you’d have to treat and hope that having an effect on spinal stenosis or is that still to be determined from your own natural history work? Thanks.

Jan Mikkelsen

I think, it's a great, great, great, great question. I think, I would take from where I got confident. Jonathan will go out and can explain when it's closely because it's actually pretty well known. Where I got confident is this our preclinical model where we couldn’t really prevent the premature fusion of the synchondrosis. Meaning is that if we give TransCon CNP after then we have really the impact we want to have on the forearm. And this is where I actually believe that it gives me a confidence that I really hope that we have an opportunity to really, really address one of these severe morbidities spinal stenosis.

Dr. Jonathan Leff

So, Jim I think it’s pretty clear that the spinal stenosis begins to occur very, very early in beginning near birth. And the way you know that though is heavily dependent on the treatment patterns at the sites. So, there’s some centers that routine we measure MRI in everybody. And of course when you do that, you see a lot of spinal stenosis that would otherwise go unnoticed, even as high as 47% of children in the first two years, if you do routine MRIs. Other sites don’t do MRIs other than for clinical reasons and they will see a little bit less. But, I think it’s really clear that you start to see changes soon after birth, which is why we’re so eager to get down to the neonates as soon as we can to make the biggest difference.
