Thanks Mike. I'd now like to give an overview of the progress we’ve made at Viking in 2016 and early 2017. I’ll first discuss our two lead programs VK5211 for hip fracture and VK2809 for fatty liver disease and hypercholesterolemia. Following that, I’ll provide an update on our newest program VK2809 for the treatment of glycogen storage disease type Ia, a rare orphan disease, as well as our VK0214 program for X-linked adrenoleukodystrophy. VK5211 is a potentially best-in-class orally available non-steroidal small molecule selective androgen receptor modulator or SARM. In early studies, VK5211 demonstrated a stimulatory effect on lean body mass and bone mineral density that may offer significant benefits to patients recovering from hip fracture surgery. Based on this preliminary profile, in 2015, we initiated a Phase 2 clinical trial of VK5211 in patients who’ve recently suffered hip fracture. This trial is a randomized, double-blind, placebo-controlled, parallel group international study designed to evaluate the efficacy, safety and tolerability of VK5211 in up to 120 patients. Patients in the study are randomized to receive VK5211 doses of 0.5 milligram, 1 milligram, 2 milligrams or placebo, once daily for 12 weeks. The study's primary endpoint was to evaluate the effects of VK5211 on lean body mass after 12 weeks of treatment. Secondary and exploratory objectives include assessments of functional performance, quality-of-life, and activities of daily living, as well as safety, tolerability and pharmacokinetics. As of today, we are continuing to enroll patients and currently expect to report top line data from this study around the middle of the year. More than 300,000 people each year in the U.S. are hospitalized following a hip fracture. These patients experience losses of bone and muscles at accelerated rates, placing them at increased risk of further morbidity, refracture and prolong disability. It is our hope that results from this Phase 2 trial will demonstrate VK5211’s ability to provide therapeutic benefits to these patients, for whom there is currently no treatment. We are also currently conducting a Phase 2 study with our VK2809 program. VK2809 is a novel orally available small molecule thyroid receptor agonist that possesses selectivity for liver tissue, as well as the beta receptor subtype. Prior data have shown that treatment with VK2809 leads to rapid histologic improvements in animal models of hepatic steatosis, as well as significant reductions in LDL-cholesterol, triglycerides and atherogenic proteins in humans. In 2016, we announced the initiation of a Phase 2 trial in patients with nonalcoholic fatty liver disease and primary hypercholesterolemia. This trial is a randomized, double-blind, placebo-controlled, parallel group study designed to evaluate the efficacy, safety and tolerability of VK2809 in approximately 80 patients with nonalcoholic fatty liver disease and elevated LDL-cholesterol. 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, triglycerides, and inflammatory markers. While we have expected this trial to be completed in the second quarter of 2017, we recently adjusted our timeline to the fourth quarter of 2017. This adjustment doesn’t reflect any problems or concerns with the drug candidate, rather a combination of factors has contributed slower than expected enrollments, including competition for patients and relatively selective enrollment criteria. We are continuing to open new sites and currently expect to have 30 sites open for enrollment in April. We believe VK2809’s unique liver targeted mechanism of action may provide differentiated benefits by simultaneously reducing hepatic steatosis, which is an important component of non-alcoholic steatohepatitis or NASH, and improving plasma lipid levels. Last November, we presented data at the American Heart Association Scientific Sessions, highlighting the effects of VK2809 on key atherogenic proteins from a Phase 1b study and patients with mild hypercholesterolemia. The results showed that treatment with VK2809 led the significant reductions in lipoprotein A and apolipoprotein B, two proteins associated with increased risks of cardiovascular disease. Reductions in atherogenic proteins, such are these, are important as they may suggest long-term benefits in patients with elevated cardiovascular risks. We believe VK2809 has tremendous promise and we continue to advance this clinical development as rapidly as possible. In addition to our ongoing clinical trials, we have two exciting preclinical programs, both of which made progress during the last quarter. Last month, we announced our newest program, which is evaluating VK2809 for the potential treatment of patients with glycogen storage disease type 1A, or GSD 1A. GSD 1A is an open genetic disease caused by a deficiency of glucose 6 phosphate, which is an enzyme which is responsible for the endogenous production of glucose from glycogen and glycogenesis. This disease results in an excess accumulation of glycogen and lipids in the liver, potentially leading to hepatic steatosis, hepatic adenomas, hepatocellular carcinoma and liver transplant. Increased triglyceride production and elevated hepatic triglyceride contents are characteristic of GSD 1A, and associated with many front manifestations of the disease. There is currently pharmacologic treatment available for these patients. Given its liver targeted activities, we believe VK2809 may represent a potential approach to reducing triglycerides, steatosis, and mitigating certain metabolic complications of GSD 1A. In the fourth quarter, we entered into a sponsored research agreement with Duke University to evaluate VK2809 in an in-vivo model of GSD 1A. Initial results from this proof-of-concept study showed that treatment with VK2809 produced rapid and substantial reductions in liver triglyceride content, liver weight, and liver weight as a percentage of body weight, compared with vehicle treated controls. Main liver triglyceride content was reduced by more than 60% in treated animals relative to vehicle treated controls, while average liver weight was reduced by more than 30% versus controls. Complete results from this work will be presented at a future scientific meeting. Given our expertise with this molecule and metabolic diseases, we believe we are uniquely qualified to develop VK2809 and GSD 1A. In order to undertake such an effort while minimizing related cash outlays, we recently announced an agreement with a dedicated healthcare investment fund to support the initial clinical developments of VK2809 in this indication. With this funding, it is our plan to file an investigational new drug application and initiate a proof-of-concept study in humans in the second half of 2017. We also made progress with our other orphan program, VK0214, for X-linked adrenoleukodystrophy or X-ALD. VK0214 is novel orally available fiber receptor beta agonist that selectively regulates the expression of gens believe to be relevant to the manifestation of the X-ALD. This is an orphan neurodegenerative disorder that can affect both adults and children. As we discussed during our last earnings call, in 2016, we conducted an in-vivo proof-of-concept study in collaboration with Kennedy Krieger Institute to evaluate VK0214 in a relevant model of X-ALD. The study was designed to evaluate VK0214’s effect on very long chain fatty acids in the so called ABCD 1 knockout model. The accumulation of very long chain fatty acids is believed to contribute to the underlying pathology of X-ALD. We’re very pleased with this study successfully achieved its primary objective, demonstrating highly statistically significant reductions in multiple very long chain fatty acids that are believed to be important in X-ALD. In our view, these results are an indication that selective thyroid beta agonist could potentially play a role in the treatment of this disease. Based on these findings, and again in conjunction with the Kennedy Krieger Institute, we recently initiated a follow-up study in the same ABCD1 knockout model to evaluate the effect of longer term treatment with VK0214 on very long chain fatty acids levels. We expect to announce the results of this study in the coming months. As our pipeline advances and grows, it is important for our leadership to keep pace. To that end, we made several key hires since our last quarterly update. Amy Broidrick was recently appointed Senior Vice President of Corporate Development. Before joining Viking, Amy served as Vice President and Head of Global Marketing, Excellence and Business Innovation at EMD Serono. Prior to EMD Serono, Amy was Vice President and Head of Marketing in Commercialization at Arena Pharmaceuticals, and previously held roles of increasing responsibility at Merck and Pfizer. Amy is the Seasoned Industry Executive and is charged with leading our corporate development and partnering efforts. Greg Zante was recently appointed Viking's Vice President of Finance and Operations. Greg joins us with more than 20 years of accounting and financial experience at public and private life sciences companies. At Viking, he is responsible for forecasting financing strategies, business development support and operational activities. Prior to Viking, Greg was Chief Financial Officer at Dance Biopharm, a diabetes-focused biopharmaceutical company, where he managed the company's financing strategy and positioned it for IPO. Greg has held senior positions at several other companies, including Sangamo, Calyx and Matrix Pharmaceuticals. He is a certified public accountant in the state of California and previously served as a senior staff accountant at Ernst & Young. Finally, Catherine, or Cass Kelleher, was appointed Vice President of Clinical Development. Cass is a skilled biopharmaceutical physician with experience across both industry and academia. Her experience in the areas of metabolic disorders and gerontology aligns with our clinical development programs, which she is charged with managing in her new role. Most recently, Cass served as Vice President of Clinical Development at Coherus BioSciences. Prior to that, she worked as global safety officer for inflammation and oncology and the Research Director in nephrology at Amgen. Cass has considerable experience at a critical point in the Company's development as we approach our Phase 2 readouts later this year. I’ll close by saying that as a result of our progress and hard work in 2016, we’re poised this year to report data from two ongoing Phase II trials in indications with significant unmet medical need. We expect to report data for VK5211 for hip fracture in mid 2017. We expect to complete our ongoing trial of VK2809 in fatty liver disease and hypercholesterolemia in the second half of the year. Beyond our clinical programs, we have established a number of strategic partnerships with organizations such as the Kennedy Krieger Institute and Duke University, which together, provide valuable support for our two pre-clinical programs addressing GSD 1A and X-linked adrenoleukodystrophy. Both are orphan diseases for which they are no approved pharmacologic therapies. We are eager to advance these programs into the clinic as quickly and efficiently as possible as we believe they represent significant unmet opportunities. This concludes our prepared statements for today. Thanks for joining us, and I would now like to open the call for any questions.
