Thanks Scott and good afternoon. My introduction today will summarize the excellent progress we are making across our rare disease endocrinology pipeline. And then, I will discuss some reflection related to why TransCon PTH has the potential to be the first true PTH replacement therapy. We have now three product candidates in clinical development, all of which will have significant clinical milestones in the next 12 months. For our most advanced candidate, TransCon Growth Hormone, the Phase 3 program continues with three trials ongoing and top-line results expected for the pivotal heiGHt trial in the first quarter of 2019. Our next program, TransCon PTH has highlighted again that we can translate positive preclinical results into successful clinical data reinforcing the target product profile. Supported by this positive Phase 1 data, TransCon PTH is proceeding towards a planned Phase 3 in this agent in Q1 2019 pending discussion with regulatory agencies. Also, we recently began dosing subject for our third endocrinology candidate TransCon CNP with a goal of top-line Phase 1 results in the fourth quarter of this year. For this program, we plan to repeat what we observed in preclinical studies and show that TransCon CNP can deliver an effective therapy through continuous CNP exposure without dose limiting cardiovascular side effects and with a once weekly demonstration. With these three candidates, we have built a diversified rare disease endocrinology pipeline. We intent to further expand this franchise by label expansion beyond the three initial indications. On this call, I would like to reflect on why Ascendis is positioned to create the first true PTH replacement therapy, one that could offer patients a treatment to more fully address all aspects of the disease. Our development process start by identifying the unmet medical need. In this case, there are around 200,000 [ph] patients worldwide with hypoparathyroidism, around 80,000 are in the United States. Patients suffer diverse range of both short and long-term symptoms. The short-term symptoms can include muscle cramps, seizure, and altered mental state. Despite currently available therapies, the majority of patients still experience these severe symptoms and reduced quality of life. Over the long-term, patients have additional complications such as tissue calcification and abnormal bone turnover. Of specific concerns are the four-fold increased risk of renal disease compared to healthy controls. Again, this is despite currently available treatments. The economic burden of hypoparathyroidism is also high. Studies of patients in the U.S. show 79% of patients require hospital stays or ER visits. 85% are unable to perform household duties, 20% have disease-related change in employment. Clinical research conducted by NIH and other group has demonstrated the benefit of giving PTH 1-34 as subcutaneous infusion by insulin pump in patients with hypoparathyroidism. This PTH 1-34 infusion provided the closest approach to a physiological replacement therapy to-date. The underlying product concept of TransCon PTH is to reproduce basic biology. The goal is simply replace the missing hormone, provide the right concentration of the hormone in the blood 24 hours a day. By fulfilling these two elements, we believe we can restore normal biological function. We know the strategy of replacement therapy works with high success when treatments are based on the replacement of the identical compound such as daily growth hormone and insulin. To realize our TransCon PTH product candidate, we looked in our extensive library of TransCon linkers and carriers. We selected a combination that can deliver sustained level of PTH 1-34 over 24 hours a day with a flat, steady state exposure within the normal physiological trends. Another question we often asked is can others match our TransCon PTH target product profile. Without the TransCon platform, we believe it would be extremely difficult to develop a product, providing the same physiological PTH replacement therapy. For TransCon PTH, we have established a simple and clear scientific rationale and product design. With each profile, we believe it can become a new standard of care for patients with hypoparathyroidism. Finally, we believe our TransCon PTH is supported by an established regulatory pathway where extensive experience with PTH 1-34 and PTH 1-84 should enable their management from Phase 1 to Phase 3. We are planning to initiate a Phase 3 program in the first quarter of 2019. We are executing on all fronts according to our goals and timelines. The Phase 1 trial is now completed. The preclinical safety program to support Phase 3 indication is being finalized and Phase 3 manufacturing at commercial scale is in place. We have also developed a simple and easy to use pen device for use in the Phase 3 program. We continue to believe that there remains a significant unmet medical need and opportunity for us with a differentiated PTH replacement therapy. Our approach for product development reflects our core values a cornerstone with the science. Finally, our platform and product development and commitment provide long-term sustainability by supporting a steady stream of product candidate across multiple therapeutic areas. Finally, I would also like to welcome Tom Larson, who joined Ascendis as Chief Commercial Officer in April. Tom has a broad commercial background and he is heading us and leading us towards commercialization, our internal strategic goals. Now Jonathan will review our clinical progress.
