Thanks Mike. During the second quarter, we at Viking continued to advance each of our four programs toward important inflection points. With respect to VK5211 our novel selective androgen receptor modulator for musculoskeletal disorders. As I mentioned in my introductory comments, we recently announced that results from our Phase 2 study in patients recovering from hip fracture have been selected for presentation as part of the oral plenary session of the American Society for Bone and Mineral Research or ASBMR 2018 Annual Meeting. In addition, we've been notifying that are abstract received the 2018 most outstanding clinical abstract award by the ASBMR conference organizers. It is a real pleasure and an honor to be selected for this high-profile presentation and receive this award and we believe it speaks to the quality of the data as well as the potential importance of VK5211 in this indication. As a reminder, VK5211 is designed to selectively stimulate muscle and bone formation with reduced activity in peripheral tissues such as skin and prostate. Following surgery to repair hip fracture, many patients experience a loss of bone and muscle at accelerated rates placing them at increased risk of further morbidity, refracture and prolonged disability. For these reasons, hip fracture is a serious medical condition and as our population continues to age we believe the incidence of hip and other fracture injuries will continue to increase. It is our belief that VK5211 may represent an important treatment option for these patients by stimulating the formation of bone and muscle thereby improving musculoskeletal health and facilitating recovery from the injury. Topline data from our Phase 2 study were announced last November. The results showed that the trial successfully achieved its primary endpoint demonstrating statistically significant dose-dependent increases in lean body mass, less head, following treatment with VK5211 as compared to placebo. The study also achieved important secondary endpoints demonstrating statistically significant increases in appendicular lean mass which is muscle in the limbs and total lean body mass for all doses of VK5211 compared with placebo. In addition though not powered for significance, endpoints assessing physical functions showed numerical trends favoring treatment arms. Importantly VK5211 also demonstrated encouraging safety and tolerability in this study with no drug-related serious adverse events reported. During the first half of this year, our team has been preparing for meeting with the FDA to review options for the future development of the VK5211 program in hip fracture. In the second quarter, we submitted request to the FDA for type C meeting to discuss the potential regulatory path forward in this setting. We are pleased to report that the FDA has accepted our request and we expect the meeting to take place in the third quarter. As we have discussed previously, in our view any subsequent studies of VK5211 in orthopedic indications would be best executed by a partner particularly one with an existing bone or musculoskeletal franchise. We are currently exploring partnering opportunities that will allow us to optimize the value of VK5211 and move the program forward in the most efficient manner possible. We will provide updates on these activities as warranted. I’ll now provide an update on progress with our small molecule thyroid beta receptor agonist VK2809 which is currently being evaluated in the Phase 2 trial in patients with nonalcoholic fatty liver disease and hypercholesterolemia. In the second quarter, we announced that enrollment had been completed in our Phase 2 trial, and that we expect the data to be available in the second half of the year. The study is continuing and we remain on-track to report results later this year. In addition, the trial Data Safety Monitoring Board continues to receive regular updates from the study, and has continued to allow the trial to proceed as planned. As a reminder, VK2809 is a novel, orally available, small molecule thyroid receptor agonist, that possesses selectivity for liver tissue, as well as the beta receptor subtype. Preclinical studies have demonstrated that treatment of VK2809 leads to rapid histologic improvement in animal models of liver disease, including a model of diet-induced and biopsy confirmed NASH, in which VK2809 treated animals demonstrated statistically significant improvements in steatosis, fibrosis, and the NAFLD activity score. In a prior Phase Ib study, and subject to its mild hypercholesterolemia, VK2809 was shown to significantly reduce not only LDL-cholesterol and triglycerides, but also both lipoprotein A and apolipoprotein Billion, two proteins associated with increased risks of cardiovascular disease. These data suggests potential long-term cardiovascular benefits that may extend beyond those provided by LDL reduction alone. For these reasons, VK2809 profile to-date suggests promise in diseases that result from lipid dysregulation, as well as those related to liver fat such as NASH. The ongoing Phase 2 trial is a randomized double-blind placebo controlled parallel group study designed to assess the efficacy, safety, and tolerability of VK2809 in patients with elevated LDL-cholesterol and nonalcoholic fatty liver disease. Patients are being randomized to receive once daily oral doses of VK2809 or placebo for 12 weeks, followed by a four-week off drug phase. The trial's primary endpoint will evaluate the effect of VK2809 on LDL-cholesterol after 12 weeks compared to placebo. Secondary and exploratory endpoints include assessments of changes in liver fat content, plasma lipids and inflammatory markers. We look forward to sharing the results from this study later this year. In addition to these two clinical programs, Viking is advancing two orphan disease programs. The first is evaluating VK2809 in glycogen storage disease type Ia or GSD Ia. The second is evaluating VK0214 in the setting of X-linked adrenoleukodystrophy or X-ALD. Both, GSD Ia and X-ALD, are devastating rare diseases with no available treatments. We've made significant progress with each of these programs over the past year. In our glycogen storage disease program, we are evaluating VK2809 as a potential treatment to reduce liver fat and improve a patient's overall metabolic profile. GSD Ia is an orphan genetic disease caused by a deficiency of glucose-6-phosphatase, an enzyme responsible for the liver's production of glucose from glycogen and gluconeogenesis. The disease results in increased triglyceride production and elevated hepatic triglyceride content. This can potentially lead to hepatic steatosis, the development of hepatic adenomas, and hepatocellular carcinoma. We have previously shown that VK2809 reduced this liver fat in an animal model of GSD 1, known as the glucose-6-phosphatase knockout. These data were presented last year at the international Congress of inborn errors of metabolism. More recently, additional work has been completed, showing improvements in liver histology and positive effects on gene expression relevant to the disease. These results have been submitted for presentation at the upcoming Annual Meeting of the American Thyroid Association, scheduled for October third through the seventh in Washington DC. Earlier this year, we filed an IND to initiate a proof-of-concept study in patients with GSD Ia and we expect to begin dosing in this trial later this quarter. Our second orphan disease program is evaluating our small molecule thyroid receptor agonist VK0214, as a treatment for X-linked adrenoleukodystrophy or X-ALD. X-ALD is a devastating disease caused by a defect in peroxisomal transporter called ABCD-1. These patients are often characterized by the accumulation of very long chain fatty acids in plasma and tissue. Sustained elevations in very long chain fatty acids are believed to contribute to the severe cerebral and motor neuron toxicities commonly observed in the disease. Activation of the thyroid beta receptor is believed to stimulate the metabolism in very long chain fatty acids, providing a potential therapeutic benefit. VK0214 is an orally available small molecule thyroid receptor agonist that possesses selectivity for the beta receptor subtype and may therefore represent a potential pharmacologic approach to the disease. In 2017, Viking and our collaborators at the Kennedy Krieger Institute completed a 25-week study evaluating VK0214 in an animal model of X-ALD. The result of this study showed promising effects on plasma and tissue markers of disease, notably an improvement in very long chain fatty acid levels. We're currently conducting IND enabling work for this program and plan to file an IND to conduct a proof of concept study in X-ALD in 2019. Moving on to recent corporate milestones, during the second quarter we completed a successful offering of common stock, which resulted in gross proceeds of $77.6 million. This financing provides us with the funds needed to further advance our pipeline assets and provides a financial runway that we expect will extend into 2020. We are very grateful to the investors who participated in this offering and we absolutely appreciate the continued support of all of our investors, institutional and retail, as we move toward important value inflection points. In conclusion, I'd like to reiterate that Viking is making great progress on multiple fronts at a rapid pace, while remaining focused and thorough. With respect to VK5211 for hip fracture, we believe the ASBMR selection of our Phase 2 results for presentation at the upcoming oral plenary session, as well as the recent receipt of the most outstanding clinical abstract award, speaks to the quality and importance of this program and these data. With respect to VK2809 for liver disease and hypercholesterolemia, we're excited to have enrolled our Phase 2 trial and look forward to announcing results later this fall. And finally both of our rare disease programs continued to advance. With respect to our GSD Ia program we expect to initiate dosing and a proof of concept study later this quarter. And with respect to our X-ALD program, we are conducting the pre-IND work that we expect will allow us to initiate a proof of concept trial in 2019. This concludes our prepared statements for today. Thanks again for your support and for joining us, and I'd now like to open the call for questions. Operator?
