Thank you, Scott, and welcome to everyone on our call today.

In this quarter, we continue to advance all three of our pipeline product as planned, TransCon Growth Hormone, TransCon PTH and TransCon CNP, paving the way to establish Ascendis as a leading rate disease company, the continued enrollment according schedule in the Phase 3 heiGHt Trial for TransCon Growth Hormone in pediatric growth hormone deficiency.

We have also enhanced the Phase 3 progress with the addition of our switch study and now progressing towards introducing our operating income in the extension study. For TransCon PTH, we are on track to submit filing this quarter in Australia and to initiate a Phase 1 trial during the third quarter.

For TransCon CNP, we are on track to file an IND for similar filing during the fourth quarter of this year. We presented positive data supporting the potential best-in-class profile of all three programs at ENDO. All this development moved us forward to our Vision 2020 strategic goal and our plan to become a leading integrated rare disease company.

To date, I have a few objections on our most advanced product candidates TransCon Growth Hormone. There have been many key learnings during the last 30 years regarding the winning strategies for commercially successful growth hormone product.

These are informed by real world experience with the many available daily growth hormone products and efforts with long acting growth hormone. We have seen what works and what does not. We have learned with attributes physician and patient for [indiscernible] therapy.

Let me share some of these observations as it relates to the development of the long acting growth hormone products. First, it’s not enough for a long acting growth hormone product to get approved. The path is most high for being a successful commercial product.

For example, as you may be aware, a long acting growth hormone product was approved [indiscernible] in the U.S., and another product was approved in Europe [indiscernible]. To be commercially successful, we believe the long acting growth hormone needs to have comparable safety, efficacy and tolerability to daily growth hormone with no compromises.

In addition, it also needs product features such as an easy-to-use device, a single-low injection volume less than 0.6 milliliter, a small needle in room temperature ability.

Related to efficacy, what is the expected path for height velocity? The long acting product should show first year height velocity that is in time with daily growth hormone products. In the most recent Phase 3 registration trials in children with growth hormone deficiency.

Daily growth hormone dosed at 0.21 milligram per kilo per week a common AU dose resulted in a growth velocity of 10.5 to 12 centimeter for the first year. In a well controlled U.S. trial, the highest dose probably used in the U.S. of 0.35 milligram per kilo per week showed growth velocity of around 14 centimeter for the first year.

We're very pleased that our TransCon Growth Hormone Phase 2 study extra relevant doses for both the U.S. and EU. The results showed that expected dose dependent growth velocity that gave us confidence to move into Phase 3 with our TransCon Growth Hormone.

In our view, a long acting growth hormone product must fully mimic all the effects of endogenous and daily growth hormone on all tissues. This benefit including catch-up to stay in growth velocity, improved body composition including optimizing fat mass and muscle, better home health and improved quality of life.

Related to safety, a new long acting growth hormone product should also align with data collected from the 20 years of daily growth hormone use, that is such new product should not compromise safety of course unexpected side effects.

It also means a low level of non-neutralizing antibodies in line with daily products and no incidents on neutralizing antibodies, and immunogenic effect that had shown -- being a showstopper for several new products in their therapeutic areas.

Finally, we believe the tolerability of a long acting growth hormone product must also be comparable to current daily growth hormone products, patient plethora and easy to use device providing a single small injection volume with a fine needle to make the injection as painless as possible.

For optimal convenience, there also plethora room temperature ability. We have taken all of these learnings into account when designing TransCon Growth Hormone. We've started and iterated what it takes to be a leader in this market and incorporated these features in our target product profile for TransCon Growth Hormone.

We are confident that the best-in-class product would become the ultimately market leader. Now, let me turn the call over to Jonathan for our pipeline of the results..

Thank you, Jan. We continue to make excellent progress with all three of our rare disease endocrinology pipeline candidates. This included a strong showing of data on all three programs at the recent Endocrine Society Annual Meeting in Orlando, where we continued to build awareness of our company and pipeline within the endocrinology community.

Our Phase 3 program for TransCon Growth Hormone continues to progress as planned, including enrollments in the global heiGHt trial as well as preparations for the extension phase of heiGHt and initiation of the switch study later this year.

We continue to see enthusiasm for the heiGHt trial across our worldwide network of sites, and we recently held another investigator meeting to brief new site that are being initiated. We continue to see additional approvals and the initiation of sites in new geographies.

The trial will ultimately be open for enrollment in close to 20 countries across Australia, Canada, Europe, Middle East, New Zealand and the U.S. With these efforts, we are gaining momentum and we remain on track to complete enrollment during the fourth quarter of 2017.

As a reminder, the heiGHt trial is a randomized open-label active controlled Phase 3 trial, comparing children with growth hormone deficiency, receiving once weekly TransCon Growth Hormone to those receiving injections of daily growth hormone, each dosed at 0.24 milligram per kilogram per week.

Using a similar design to our Phase 2 active control study, heiGHt is evaluating the safety, efficacy and tolerability of TransCon Growth Hormone in the non- inferiority design with the primary endpoint of heiGHt velocity at 12 months.

The results of our randomized controlled Phase 2 trial give us confidence in the potential results of the heiGHt trial, given the dose response and demonstrated heiGHt velocity which appeared comparable to daily human growth hormone in that trial.

During the first quarter, we also made important progress with planning for 2 additional trials in our Phase 3 program, which we expect to both begin enrolling subjects this year.

All subjects in the heiGHt trial may enroll in an open-label extension study which we have named the enlightened trial, reflecting its goal to collect long-term data on our weekly TransCon Growth Hormone.

This program paves the way for commercial launch that are providing a platform to familiarize physicians with our TransCon products and the auto-injector. We are also well underway with planning for the switch study which will be known as the flight trial.

We will enroll approximately 150 subjects on daily growth hormones who will then switch to receive once weekly TransCon Growth Hormone. The flights trial will also strengthen our safety database.

As Jan emphasized, establishing a safety profile comparable to daily human growth hormone is a key attribute for success of a long acting growth hormone products, both the flight and enlightened trials support this goal for TransCon Growth Hormone.

Finally, we are on track to introduce our TransCon Growth Hormone auto-injector during the enlightened trial. Our plan is to make the auto-injector available at launch. The features of our patient friendly device are backed by the results of six human factor studies that are provided a feedback on its usability and design.

As Jan described, we believe that is essential in the pediatric patient population, we have an auto-injector available to support a successful commercial launch. Now, let me provide an update on the TransCon PTH program, which is progressing well towards the clinic.

As you know, we are developing TransCon PTH to address limitations of current therapies for hypoparathyroidism, which do not address all aspects of the disease. The infusion-like profile TransCon PTH is designed to deliver a study PTH exposure within the normal range.

We believe the TransCon PTH may more fully control all aspects of the disease including serum calcium. Additionally, our product is designed to control serum phosphate, urinary calcium and to improve quality of life.

At ENDO, we demonstrated the promising pharmacokinetic and pharmacodynamic profile of TransCon PTH in our pre-clinical pharmacology studies in both rats and primates. We have shown this infusion-like profile following a single injection, which is maintained over 24 hours.

In the ENDO posters, new data also show this profile was maintained in primates over 28 days with incredibly low variability. Mimicking what FDA scientists suggested at the Natpara Advisory Committee Meeting would be the optimal PK profile for a PTH replacement therapy.

We now late breaking poster at ENDO, we also shared results from studies of rats suggested to thyroparathyroidectomy towards efficient in PTH providing an ideal animal disease model. This data reinforced our TransCon PTH can normalize serum calcium and serum phosphate.

Finally, the late breaking poster also summarized our studies in non-human primates, which show the TransCon PTH also significantly reduced urinary calcium excretion.

Typically, increased serum calcium result in increased urinary calcium excretion with the filter load of calcium to the kidney increases; this was a pleasant and surprising results from our primate studies suggesting that the candidate has a unique and differentiated profile from the currently available therapies.

By taking to normalize PTH levels throughout the day, we have designed TransCon PTH to optimally manage all aspects of hypoparathyroidism. For next steps, we are on track to summit the filing for TransCon PTH this quarter with the Therapeutic Goods Administration in Australia and initiate a Phase 1 trial during the third quarter.

Now, let me update you on our third product candidate. TransCon CNP, which is in development to treat achondroplasia and related diseases. TransCon CNP as a long acting CNP pro-drug designed to allow the therapeutic CNP levels without the hypotension that is limited current therapies in clinical development.

In relevant animal models, we have shown no change in blood pressure following once weekly administration of TransCon CNP. In contrastm a daily administered CNP which led to hypotension at similar doses.

Recent data showed that the promising profile TransCon CNP, we now completed the six months juvenile primate study for all dosing cohorts none of which were limited by side effects. In summary, a dose response in linear growth of tibia was seen with TransCon CNP over the six months trial.

So the highest dose, growth was increased by more than 70% compared to untreated control. The response appears to be dosed proportional. Trends were also seen in older linear growth. We've also evaluated TransCon CNP in an achondroplasia mouse model, which demonstrated effects on some of the more disabling traits associated with achondroplasia.

This included positive results on bone growth and the potential for TransCon CNP to reverse the achondroplasia phenotype in mice, including prevention of calcification of the cartilaginous joints in the foramen magnum. Our goal is to reduce the devastating complications of this disease, not simply enhance heiGHt.

We remain excited about the potential for TransCon CNP as there're currently no approved therapies for this serious condition. We continue to work towards filing an IND or equivalent during the fourth quarter of this year.

I'm enthusiastic about the data that we collected to support each of our three pipeline candidates and their differentiated product profiles. We continue to prepare and submit additional analyses from all three of our development programs for presentation at upcoming medical conferences.

We also look forward to further building relationships within the medical community by having a presence at these conferences. We're making progress to advance all three of the rare disease product opportunities in our diversified portfolio. Now, Scott will provide the financial updates..

Thank you, Jonathan, and thank you everyone for participating in the call today. Turning to our financial results for the three months ended March 31, 2017, let me review some highlights. We ended the quarter with cash and cash equivalents of €157.6 million and approximately 32.5 million shares outstanding.

We reported a net loss of €25.1 million or €0.78 per basic and diluted share compared to a net loss of €20.5 million or €0.82 per basic and diluted share during the same period in 2016. Research and development costs for the quarter were €20.6 million compared to €16.2 million during the 2016 quarter.

Higher R&D costs in Q1 2017 reflect preclinical development and manufacturing costs for two new rare disease pipeline candidates TransCon PTH and TransCon CNP, partly offset by lower manufacturing costs for TransCon Growth Hormone in the first quarter of 2017 compared to the prior year's quarter.

General and administrative expenses for the 2017 quarter were €3.3 million compared to €2.9 million during the 2016 quarter. The increase is primarily due to higher personnel costs partly offset by a decrease in professional fees.

As a reminder we expect our R&D expenses to vary from quarter-to-quarter as we invest in and advance our wholly-owned internal pipeline programs primarily due to increase in clinical trial costs related to advancing and expanding our Phase 3 program and variable expenses related to clinical supply and validation of our commercial manufacturing process for TransCon Growth Hormone, increasing cost related to the initiation of a Phase 1 clinical trial and Phase 3 enabling chronic tox manufacturing and other activities for TransCon PTH, and ongoing preclinical development and manufacturing activities to support an IND or equivalent filing by year end for TransCon CNP.

We are pleased with our execution this year advancing our rare disease pipeline. Operator, we are now ready to take questions..

Thank you. [Operator Instructions] Our first question is from Jessica Fye with JP Morgan. Your line is now open..

Hey, guys. Thanks for taking my questions.

Couple of from me, first, is there anything more specific you could give us around the where we are enrollment for the heiGHt trial? Second, curious if there is any kind of detail you could provide on how to think about quarterly expense trends over the remainder of the year? And lastly, question I've been getting from investors is what's your view on to the extent long acting growth hormones were to show numerical interiority still within kind of non-interiority criteria.

What do you think kind of max tolerable difference from physicians would be for uptake? Thank you..

Okay. Jess, I'll start your first question was on enrollment. And we've said and we continue to say that our enrollment is moving along as planned, we're very pleased. We planned to finish enrollment by the fourth quarter. And we still fully expect to meet that milestone..

On the quarterly expenses, we don't provide specific guidance, Jess, as you know, but in the past our expenses have been lumpy quarter-to-quarter. And you should expect that somewhat going forward. .

So, Jess, I would take your last question Jan, here. I also think of accretion needs to be taking in a larger perspective because just taking one single element out from the entire integrity of the product portfolio need to fulfill. I think efficacy, safety and tolerability and also product these are need to be optimal.

If you just go into one single element with needed to efficacy then you have a lot of different efficacy models. You have those children with growth hormone deficiency. You have what we called high velocity with are the primary outcome.

If you go to adults with growth hormone deficiency, you have a complete different outcome with the typical one will be [indiscernible]. Going to narrow it down much more to attrition related to the pediatric growth hormone deficiency trial related to high velocity. You have actually dependent on the doses as you have and U.S.

dose with a higher than the European dose. The European dose is around 0.21 milligram per kilo per week. The U.S. dose is much higher effective outcome 0.35. If we go down where we running our product today, I think at least you need to show at least the same scope velocity when you compare to the European dose. What we also believe that is not enough.

We also need to show that you can move up to the U.S. relevant doses, so you also can show that not only on the 0.24 where we all compare in our daily optimal. You also need to show that you actually can get the expected growth velocity that you will expect to see out from a daily growth hormone that have been dosed up in the U.S.

relevant dose of 0.35 milligram per kilo per week. So, that is actually a lot of different kind of paths that you need to pass to have the right efficacy..

Okay. Got it. Thank you..

And I’ll just add that. Sure, you need to achieve non-inferiority for your trial to succeed. So, we would say that the bars are a little higher than you in addition need to compare favorably to the comparator agents..

Our next question is from Joseph Schwartz with Leerink Partners. Your line is now open..

I was wondering also but the heiGHt trial first of all and whether you have any insight into how the baseline gross velocity for the patient sort of have been rolling a heiGHt compares to who went into your previous study and those are competitors? And how you think that might influence the magnitude of benefit that you’re likely to see?.

Okay. Thanks. This is Jonathan, I’ll take that. We are collecting in all of our sites the baseline growth velocity. We have not actually collected clean and reviewed that data, but it tends to be fairly uniform most of these patients in most of these studies that are reported tend to grow and about 4 centimeters per year prior to entering the trials.

What’s more important is what the baseline demographics end up being, and again they tend to be relatively standard between these various trials and conclusion criteria are very similar in all of these trials. Lastly, our inclusion criteria for our heiGHt Trial are very similar to the inclusion criteria of our Phase 2 study.

So, we would expect our baseline demographics to be very close to what we saw in the Phase 2 trial..

Jan, here to add one thing comparison, we had tried to compare the demographic for all of Phase 2 trials. We have tried to compare to last U.S. trials out of [indiscernible] in North America.

We had compared to around demographics for examples [indiscernible] demographic and we basic can only see where that’s more different that not have can give any kind of reason to explain the difference we have seen in growth velocity..

Okay. That’s very helpful. Thanks. And maybe a follow-up on the hypoparathyroidism program.

What kind of biomarkers should we anticipate that you’ll be measuring and then another benchmarks for those that might be provide some interesting inside into activity in your Phase 1 study?.

What with the biomarkers are really very straightforward and they tend to be the pharmacodynamic markers and those are serum calcium, which you should look for clearly serum phosphate. We should look for urinary calcium levels. And then importantly, we should look for the expected suppression of endogenous PTH 1 to 84.

Since we’re giving 1 to 34, you can actually look for treatment effect by looking at suppression of PTH 1 to 84, which we intend to do..

Are there any bone markers or anything else that you’re going to be posting?.

Of course, there is a whole panel of bone markers which will be following as well. I should have mentioned that. And we expect them to normalize from the abnormal state at baseline..

Our next question is from Alethia Young with Credit Suisse. Your line is now open..

Hi, guys thanks for taking my question, it's actually Derek for Alethia. Only one question for me, my question is around adult with growth hormone deficiency.

So looking at TransCon Growth Hormone, I think it's more differentiated in terms of BMI which is more important in adults being deficient, so I'm wondering what's your thought around the timing of the adult Phase 3 trial if any and the market opportunity there? Thank you..

I'm sorry Derek, the timing of our Phase 3 trial.

Can you just clarify your question?.

Yes, the timing of the adult Phase 3 trial for TransCon Growth Hormone?.

On adults, so we've not announced our plans for the adult trial, but it would be a natural trial for us to do in follow-up. We've said that it will not be part of the initial filing package, so that will be a follow-on study..

I think it's extremely irrelevant question you're coming up because it's not only enough to on what we call growth velocity, but also all others effects that you expect to get out from the growth hormone treatment.

But what we've seen and why we're confident that we can get the same effect at endogenous and daily growth hormone is that we had compared the BMI development in our Phase 2 trial, and we actually are getting expressive the same results of the BMI development for six months in the treated children with exactly one change compared as you expect it to see with daily growth hormone treatment..

Our next question is from Liana Moussatos with Wedbush Securities. Your line is now open..

Can you comment on the status of potential partnerships this year?.

So, with regard to partnerships, particularly the Sanofi partnership and the Roche Genentech partnership, we don't provide any guidance or insights. Those programs are completely in the hands of partners, and we received some sort of milestone that's material. We'll make an announcement as appropriate.

With regards to additional partnerships, that may or may not come, we don't give specific guidance on those either, although as you highlight I think the continued progress of the pipeline is sort of revealing the power of the TransCon platform to others..

[Operator Instructions] Our next question is from Jim Birchenough with Wells Fargo. Your line is now open..

Just on the switch study just wondering, if you could speak to the goal of that study and maybe a little bit more about the design? I'm wondering if you're looking to enroll adults with suboptimal metabolic or body composition metrics and show improvement there and on the children if you're looking to show improvement in growth velocity in those with suboptimal growth velocity on existing therapies.

And then I've got a follow-up..

So, the switch study is primarily a safety study. It was recommended by us to the agencies but very well embraced I would say because our initial program was relatively on the smaller side, it was only the heiGHt trial.

So we start by enhancing our safety data dates and providing essentially 300 patients with at least six months of safety data that would compare favorably by any measure even to the ICH numbers, which do not of course apply to rare diseases.

So, it's really to bolster our safety database and further provide confidence in the safety package as we approach the agencies. So FDA and EMA have both clearly embraced this.

In terms of who is enrolled its patients who are currently taking growth hormone therapy, who will then switch because they would prefer to be on presumably a weekly therapy versus a daily therapy. And we'll follow all of the children in this trial for heiGHt velocity of course.

Really, it will be a little more challenging to assess efficacy in this trial, although we will do efficacy assessments where we can imagine that patients will be on varying lengths of growth hormone using various products, various different devices.

So, it's a bit of a heterogeneous population unlike the heiGHt trial, which is really the go to place for efficacy. Nonetheless, we will measure efficacy and we'll probably have something to say about efficacy from this trial as well..

And then maybe just a follow-up on TransCon PTH.

Could you maybe walk us through the opportunity for more optimized product particularly one that has an effect on calciuria? And maybe start with current use of Natpara as you understand it and how you think you could broaden the opportunity with more effective product?.

So, Natpara is off to a good start. It's being used as you might expect in more severe patients. But even where it is used, I think it's pretty clear at least from the trial data, that it controlled some aspects of the disease reasonably well like serum calcium, but it's not -- well I'll get back to that and does not control urinary calcium very well.

But back to serum calcium, the spot values are often in the low normal to normal range. But what it does not do is affect the levels of hypercalcemia or hypocalcemia that we're seeing in the clinical trial. In fact, there was no difference from placebo.

But basically, what you're seeing is there is an upward movement of serum calcium into or approaching the normal range that is tend to be very volatile either too high or too low. And that of course is problematic and there is no effect on urinary calcium.

All of this according to FDA and we agree with this is very predictable because of the pharmacokinetics of Natpara, which provide coverage above or within the normal range for only about 12 to 15 hours of the day.

But during the first 12 to 15 hours of any day, you have presumably good control of all of those parameters, but then you lose it for the back half of the day. And net-net is that you don't control hyper or hypocalcemia or urinary calcemia -- sorry hypercalciuria.

And that leads us to the design of our product, which is an infusion-like property that replaces PTH 247 within the normal range. And that really is the goal of replacement therapy for a deficient hormone. So, that's why we have such confidence in what we'll see in Phase 1 and beyond..

But I guess in terms of the commercial opportunity what I'm getting at is, do you see this as we think about the opportunity, should we look at Natpara and say this is a better replacement therapy and it will take dominant share from Natpara or are the patients with hypoparathyroidism that aren’t being treated because of deficiencies in that product that could be addressed with TransCon PTH.

Just trying to understand how we should think about the commercial opportunity?.

I think from the commercial perspective, we see it’s quite different compared Natpara. We see that at the true replacement therapy for patient that is missing and having too small amount of PTH.

And it’s a complete different way of treatment as Jonathan saying is because we addressed all the aspect of the disease meaning that when you look on the shortcut of Natpara related to not giving any impact on for examples the urinary calcium. It’s not having any effect on hypo and hypocalcemic some of that really the server part of disease.

We actually see that in a complete different product, that is highly differentiated compared to Natpara because it’s actually are in a position where we really address the fundamentals of the disease and are in the position that we actually to normalize the PTH level of this patient group.

And the only way you can do that today in current way is to take on infusion con you know from insulin area and give the PTH1-34. And this is where they have shown when patients are on infusion pump where we have to keep the PTH all in the physiological range.

You actually can be in a position, you address all aspect of the diseases and this is where we see becoming. We coming in with an optimal way to treat this patient given the true replacement therapy so that all this can have a PTH deliver in the normal physiological range ensuring both efficacy and safety, both related to short-term effect.

But I think we’ve seen important to the long-term effect, we need to the classification specific in treatment in all the patients in the body..

Thank you. And I’m showing no further questions. Ladies and gentlemen, thank you for participating in today’s conference. You may all disconnect. Everyone have a good day..
