Thanks Greg. I'll now provide an update on the progress with our development programs beginning with our lead program VK2809. VK2809 is an orally available small molecule agonist of the thyroid hormone receptor that possesses selectivity for liver tissue as well as the beta receptor subtype. To date, the clinical studies have demonstrated compelling evidence supporting the potential of VK2809 in the treatment of multiple metabolic disorders, including NASH and fibrosis. Phase 1 studies in healthy volunteers, as well as in subjects with mild hypercholesterolemia have shown that treatment with VK2809 produces significant reductions in plasma lipids, including LDL cholesterol, triglycerides and atherogenic proteins. In addition, we previously completed a 12-week Phase 2 study in patients with non-alcoholic fatty liver disease, and hypercholesterolemia. This study successfully achieved its primary and secondary endpoint, with patients receiving VK2809 demonstrating highly statistically significant reductions in liver fat content, as well as improvements in LDL cholesterol. VK2809 also performed well on secondary measures demonstrating significant reductions in other plasma lipids such as triglycerides, apolipoprotein B, and lipoprotein A. Importantly, no serious adverse events were reported in this trial among patients receiving VK2809 or placebo. Initial data from this study as well as follow-up data have been highlighted in multiple oral presentations at key scientific meetings. Most recent among these was an oral presentation at the 2020 International Liver Congress or EASL, where follow-up results from the study were presented. This presentation highlighted VK2809's durable benefit, including among patients with key NASH risk factors. At week 16, four weeks after completion of the 12-week treatment period in the study VK2809 treated patients maintained a statistically significant 45% median reduction in liver fat content, compared to a 19% reduction among patients receiving placebo. Additionally, at week 16, 70% of VK2809 treated patients maintained a response defined as experiencing a greater than or equal to 30% relative reduction in liver fat content from baseline. Notably, all patients receiving the lowest evaluated dose of five milligrams of VK2809 daily maintained a response at week 16. In addition to these data, new analyses of week 12 study results demonstrated significant reductions in liver fat among patients receiving VK2809 compared to placebo, regardless of the presence of common NASH risk factors, including elevated baseline levels of ALT, a body mass index greater than 30, hypertension or Hispanic ethnicity. The totality of data from our Phase 2 study demonstrate VK2809's exceptional low dose potency on liver fat and plasma lipids, as well as its durable effect and encouraging safety and tolerability profile. We believe that the observed reductions in other lipids maybe an important indicator of cardiometabolic benefits for patients. This is an important distinction, which we believe represents an advantage, when contrasted with mechanisms that have been associated with elevations in lipids known to increase cardiovascular risk. Overall, we believe the data to date position VK2809 as a best-in-class compound for the treatment of patients with NASH and fibrosis. In late 2019, we advanced this program into a Phase 2b clinical trial. This trial called VOYAGE is a randomized double-blind placebo-controlled, multicenter trial designed to assess the efficacy, safety and tolerability of VK2809 in patients with biopsy-confirmed NASH and fibrosis. The study is targeting enrollment of approximately 340 patients across five treatment arms. The target population includes patients with F2 and F3 fibrosis, as well as up to 25% with F1 fibrosis. The primary endpoint of the study will evaluate the change in liver fat content, as assessed by magnetic resonance imaging proton density fat fraction from baseline to week 12 in patients treated with VK2809 as compared to patients receiving placebo. Secondary objectives include the evaluations of histologic changes assessed by hepatic biopsy after 52 weeks of treatment. During the first quarter, patient enrollment for this study continued at sites both within and outside the US. We continue to navigate a challenging enrollment environment, due to the COVID-19 pandemic. That said our US sites remained open through the first quarter, with none close to pandemic related issues. Outside the US, the environment is also challenging with many sites experiencing local lockdown restrictions that impact screening flow. Despite these hurdles, we have remained active in our site engagement efforts and continue to add sites both in the US and outside the US. We currently remain on track to complete enrollment in this trial in the second half of 2021. In parallel with our VOYAGE study efforts, we are also taking steps to prepare for the anticipated Phase 3 development of VK2809. As discussed on our last update call, we recently completed the formulation study evaluating tablet and soft gel formulations of VK2809 with potentially improved commercial profiles. In addition, we also completed the study of VK2809 in patients with varying degrees of hepatic impairment. Both studies generated useful data for further planning and development activities and we look forward to continued progress on the clinical and regulatory fronts in the months ahead. I'll now provide an update on our second clinical program VK0214. VK0214 is an orally available small molecule thyroid hormone receptor agonist with selectivity for the beta receptor subtype that we're developing as a potential treatment for the rare neurodegenerative disease called X-linked adrenoleukodystrophy. Last year we initiated a Phase 1 first-in-human study of VK0214. This trial is a randomized double-blind placebo-controlled single ascending and multiple ascending dose study in healthy volunteers. The primary objectives of the study include the evaluation of the safety and tolerability of VK0214 as well as the pharmacokinetics of VK0214 following single and multiple oral doses. We continue to make excellent progress with this study and expect to complete dosing in healthy volunteers in the near-term. Pending an evaluation of the data, we plan to initiate a Phase 1b study of VK0214 in patients with X-ALD. We currently expect to initiate this trial around the middle of the year. With two programs advancing through clinical developments it is important to note that our balance sheet remains strong. As Greg stated, we ended the quarter with approximately $242 million in cash which gives us ample runway to complete multiple clinical milestones that will drive future value for the company. In conclusion, we continue to make progress in the first quarter with both of our ongoing clinical trials. With VK2809, we expect to complete enrollment in the 52-week Phase 2b VOYAGE study in patients with NASH and fibrosis in the second half of 2021. Based on data to-date, we continue to believe that VK2809 they represent a best-in-class compound for the treatment of NASH and fibrosis. With VK0214, we are nearing completion of a Phase 1 single and multiple ascending dose study in healthy volunteers. Pending a successful outcome, we plan to initiate a Phase 1b study in X-ALD patients. We believe VK0214 represents a novel approach to treating this debilitating disease and we look forward to evaluating its effect on key biomarkers. Finally, we ended the quarter with a strong balance sheet providing the runway to complete our ongoing clinical studies as well as other important milestones. This concludes our prepared comments for today. Thanks again for joining us and we'll now open the call for questions. Operator?
