Thanks, Scott, and good afternoon, everyone. Our goal at Ascendis is to create a leading biopharma company by bringing highly differentiated product candidates, addressing major unmet medical needs as fast and safely as possible to the patients. Beginning with our TransCon technology and algorithm for product innovation, we designed our TransCon Growth Hormone product candidate and developed it from idea stage to Phase 3 pivotal trial. This year we are seeing the results of our efforts as we are approaching the due date June 25th for TransCon Growth Hormone. We held our late-cycle meeting with FDA in April, in which FDA confirmed at that time that they are planned to meet the PDUFA action date. After the late-cycle meeting, FDA conducted a BIMO inspection at our Palo Alto site over a six-day period with no 483 observation. Finally, we and our contract manufacturers have also submitted a response to FDA's information request related to our contract manufacturing sites. We feel good about a potential US approval for TransCon Growth Hormone for the treatment of pediatric growth hormone efficiency. We believe our ongoing living discussion with FDA are progressing well. Based on the latest feedback, we believe we will get a label that will support the scientific basis for TransCon Growth Hormone having a comparable mode of action to daily growth hormone. The great thing about retaining the same mode of action is that patients, physicians and payers can rely on the at least 30 years of scientific and clinical data to predict expected treatment results for overall endocrine health, including growth velocity. But getting an approval is just another important step in our plan to build a market-leading product. We are all aware of our long-acting growth hormone preparation that have been approved, but not launched or have been launched, but then removed from the market. To have a market-leading product, we also have to provide a strong value proposition to patients, physicians and payers. For patients, our once-weekly TransCon Growth Hormone has in clinical trials shown safety, including hemogenic profile comparable to daily growth hormone and superior outcome measured by annualized high velocity in pediatric growth hormone deficiency compared to daily growth hormone. We believe our once-weekly TransCon Growth Hormone administrated with an auto-injector in a room temperature-stable presentation will reduce the treatment burden for patients compared to daily growth hormone. For physician, we believe our once-weekly TransCon growth hormone may improve patient compliance compared to daily growth hormone which potentially could lead to better outcome. And that physician finally may have a growth hormone therapy for patient and caregivers that is associated with less treatment burden compared to daily growth hormone. Largely for payer our recent US insurance claims analysis data presented at end of 2021 demonstrated that the financial benefit of treating pediatric growth hormone-deficient patients with growth hormone therapy and the dramatic need for improved adherence. We are continuing to execute on our global clinical reach and label expansion for TransCon Growth Hormone. In Europe, we expect a decision from the European Commission on our M&A for TransCon Growth Hormone in the fourth quarter of this year. In Japan, we continue to execute on the Phase III riGHt trial for pediatric growth hormone deficiency. And in China, VISEN Pharmaceuticals recently completed enrollment of its Phase III clinical trial of TransCon Growth Hormone in children with growth hormone deficiency. We also have the global Phase III foresiGHt Trial underway for adult growth hormone deficiency to support label expansion for TransCon Growth Hormone. And we continue to expect to complete enrollment of foresiGHt Trial by late 2021 or early 2022. In summary, for TransCon Growth Hormone, we are aiming to bring a highly differentiated product to the patient that can become a global leader in the growth hormone market and provide benefit to patients physicians and payers. Moving to TransCon PTH. We were excited about the 58-week results on the open-label extension of the Phase II PaTH Forward Trial in adult HP. When we reported the 26-week data, we showed that we had a potential hormone replacement therapy that demonstrated normalization of serum calcium, normalization of phosphate, normalization of phosphate calcium complex, normalization of urinary calcium. We also saw the major impact TransCon PTH treatment had on quality of life on the SF-36 functional health survey. And we saw a trending towards normalization of skeletal remodeling. Coming to the 58-week results, the open-label extension trial is the first time to our knowledge that such a large group of HP patient has been exposed to physical levels of PTH for over a year and it demonstrates how this treatment might help this patient group on a long-term basis. If I just sum up the 58-week results, what we saw was as expected, the durable response and well-tolerated safety profile that we have hoped for. All the elements of normalization of calcium metabolic and hemostasis that we observed at the 26 weeks continued at 58 weeks, including normalization of 24-hour urinary calcium excretion, along with the initial rise of bone turnover, followed by a decline trending to the mid-normal level. All this effect was observed in the absent of active vitamin D intake and the requirement for therapeutic intake of calcium supplements. What is remarkable and rewarding to me is that, these 58 patients continue to participate in the open-label extension. I believe this is a reflection of the positive impact TransCon PTH is having on this patient short-term symptoms and quality of life. I have never been part of a trial where we started with 59 patients and have 58 patients more than one year into an open-label extension. The patient demographic in our Phase 2 trial showed a very mixed population, subjects suffering from post-surgical HP, idiopathic HP, autonomous HP some with kidney stones, renal insufficience, some just recently diagnosed with HP and some with HP for more than four years. Some patients had mild pills and some had up to eight grams of calcium supplement plus active vitamin D at baseline. Despite this the wide variety of severity and disease background, 58 still continued in the open-label extension. I believe the improvement in quality of life is driving that. Looking at the adherence level, it was 99.8%, strongly suggesting that TransCon PTH is providing a benefit for the short-term symptom, as the patients don't want to miss a shot. Everything I've seen with all the data suggests that patient benefit from TransCon PTH, regardless of severity and disease background. We have seen that with the data with the adherence with the trial retention and now we're also hearing the same measures from the physicians being part of the trial. Some physicians are now saying that all patients may benefit from TransCon PTH, not just because of biochemical control, but because the patient's lives are improving. The patient can now become active again, can return to work. This is exactly why I see TransCon PTH addressing a major unmet medical need for the patient, but also for the society, by enabling the patient to find active employment and work again. So when I look at the data, when I hear the stories from the patient, when I hear the stories from the physician, I feel so optimistic. I'm so hopeful that we really can help the more than 200,000 patients that are in the US, Europe and Japan and for the first time can potentially provide a formal replacement therapy that normalize their lives for them, not only based upon short-term symptoms but also potentially on long-term complication. Later this year in the fourth quarter, we expect to have the 84-week top line OLE update from PaTH Forward. We also expect to report our top line Phase III PaTHway Trials result by the end of the year. We believe the data being generated support a profile for TransCon PTH to be a potential first-line therapy for hypoparathyroidism. At the time of regulatory submission planned for the first half of 2022, we expect to have a solid data packet with both long-term 84-week data from our Phase II PaTH Forward Trial and six-month randomized controlled data from the Phase III PaTHway Trial. To achieve global clinical reach, earlier this month we submitted a clinical trial notification to initiate a Phase III clinical trial evaluating TransCon PTH for adults' HP in Japan. We look forward to sharing additional results later this year, as our goal is to make this important therapy available to HP patients worldwide as fast as possible. Turning to TransCon CNP. We are on track to provide an update on the clinical program in the fourth quarter of this year. As you know, we are conducting two randomized double-blinded placebo-controlled Phase II trials in children aged two to 10. The first ACcomplisH trial is a dose-escalating trial of 12 to 15 subjects in each cohort conducted mainly in North America, Australia and Europe. The second one by VISEN Pharmaceutical is a completed China trial, which is a cohort expansion trial of at least 60 subjects in – conducted in China. We are planning to keep the data blinded for one year for each cohort. Once completed, we will have a robot clinical data from two independent randomized double-blinded placebo-controlled trials. To date, the safety is everything we have hoped for. There had been no injection cycle reaction and no indication of cardiovascular risk. Our top priority is to the achondroplasia patients in developing a safe and differentiated treatment option that address the comorbidity of their disease. Turning to oncology. We hit a major milestone late last year with our first R&D for our oncology division, which is also our first IND levering the TransCon hydrogen technology for sustained intratumoral delivery. We expect to initiate dose escalation in combination with a checkpoint inhibitor in July and to have initial results for monotherapy dose escalation for TransCon TLR7/8 Agonist in the fourth quarter. For our second oncology program, we are on target to submit an IND for TransCon IL-2 beta/gamma in the third quarter of 2021. TransCon IL-2 beta/gamma is designed for systemic administration via IV route and leverage the TransCon systemic technology that you know from our endocrinology portfolio. As we have done in endocrinology, our understanding of the biology has guided us into signing a compound with independently optimized receptor buyers, potency and pharmacokinetic to create a potential best-in-class IL-2 product. Summing up, starting with a product concept are now being less than one month away from our first PDUFA action date is a significant achievement. But as I mentioned, when I started today's comments, we are not just trying to bring a product to a market, we are driving to solve major unmet medical needs that we can meet by our TransCon technologies. We want to establish Ascendis as a fully integrated global biopharmaceutical company that has a portfolio of multiple independent products that make a difference in the life of patients. We have many important milestones to execute on in 2021. I have never been more confident that we have the fundamentals in place to successfully building a leading biopharma company with multiple market-leading products in both endocrinology rare diseases and oncology. Now, let me turn the call over to Scott for a financial review before we open for questions.
