Thank you, Liz. The last several months have obviously been very exciting for UroGen. I see our recent progress not only as the beginning of what's to come for our company, but also as a major milestone for the urologic community. The approval of Jelmyto is a validation of our technology and the potential applicability to improve standard of care and develop non-surgical therapies for diseases such as low-grade UTUC and low grade non-muscle invasive bladder cancer. These are diseases characterized by repetitive surgical intervention and associated risks in an elderly population and with low-grade UTUC, potential kidney removal in approximately 70% to 80% of patients and a host of additional comorbidities. Literature continues to emerge about the molecular and clinical similarities between these two disease. In the recent approval and supporting data in low-grade UTUC further fuel our confidence and excitement about the potential of UGN-102 in low-grade intermediate risk non-muscle invasive bladder cancer. We have spoken quite a bit about our leading neuro-oncology pipeline over the past several months. And today, I would like to highlight the data published in Lancet Oncology along with the ongoing progress of our UGN-102 program. As we discussed on our most recent call, the FDA approval of Jelmyto was based on positive results from the Phase 3 OLYMPUS study, which has demonstrated that Jelmyto achieved clinically significant disease eradication in adults with low-grade UTUC. OLYMPUS was designed as a pivotable open-label single-arm Phase 3 clinical trial of Jelmyto to evaluate the safety, tolerability and tumor ablative effect in patients with low-grade UTUC. The trial enrolled 71 patients at clinical sites across the United States and Israel. Study participants were treated with six weekly installations of Jelmyto administered via standard ureteral catheter, four to six weeks following the last installation, patients underwent a primary disease evaluation to determine response. And the primary endpoint of the study was this complete response. Primary disease evaluation involves the ureteroscopy and wash cytology, a standard microscopic test of cells obtained from the urine to detect cancer. Patients who achieved a complete response remain followed for up to 12 months to determine the durability of disease control with Jelmyto. We intent to treat population included the 71 patients who received at least one dose of Jelmyto. 48% of these patients had tumors that were deemed endoscopically unresectable. These were patients who, according to the current standard of care, would have been candidates for immediate kidney removal. As reported in Lancet Oncology, Jelmyto achieved a complete response of 59% in the intent-to-treat population and durability of 12 months at the time of data cut-off was estimated to be 84% by Kaplan-Meier analysis. Overall, the most frequently reported adverse events were ureteral stenosis, urinary tract infection, haematuria, flank pain and nausea. No treatment-related deaths occurred. The FDA approved labeling for Jelmyto reports complete response based on the primary endpoint 58% in the intent-to-treat population. The product labeling also reports that at the 12-month time point for assessment of durability, 19 patients remained in complete response, seven had experienced recurrence of disease, nine patients continue to be followed for the 12-month duration of response and median duration of response was not reached as of the FDA approval date. You will know differences in CR and durability in our label versus the publication, reflecting the FDA method of evaluating patients, particularly given the approval was based on immature durability results. The final durability data will be available by June. And as discussed on our prior call, we will submit as soon as possible to have the label updated to reflect all patients at 12-month follow-up. We believe the longer-term data will remain consistent with the results shared to-date. As we look at the recent progress of our clinical development programs, our most advanced pipeline product candidate beyond Jelmyto, UGN-102 which is being developed for the treatment of patients with low-grade intermediate risk non-muscle invasive bladder cancer. We chose to focus on the intermediate risk group, as this is a disease that has been extremely challenging for urologist to control using standard of care surgical intervention or TURBT. Intermediate risk patients are defined as those patients with one or two of the following criteria, multifocal disease, large tumors and rapid rates of recurrence. Updated complete response and durability data in the Phase 2b OPTIMA II trial was recently included in a late-breaking abstract published in the April supplement to the journal of urology. This study demonstrated a complete response rate at three months following onset of treatment of 65%. Of those who achieved a complete response and underwent evaluation of six and nine months, 97% and 85% respectively remained disease free. Most commonly reported adverse events were dysuria, haematuria, urinary frequency, fatigue, urgency and urinary tract infection. And the majority reported as mild to moderate in severity. We look forward to sharing the detailed results in the presentation online via the virtual American Urological Association Annual Meeting in mid-May. As Liz mentioned, we remain actively engaged in discussions with the FDA to finalize the design for our pivotal Phase 3 protocol and still anticipate initiating the study in the second half of this year. We hope to communicate the final design as soon as feasible, but do not believe the ongoing discussion will delay or impact our timing for trial initiation. And with that, I would like to ask Jeff to provide an overview of commercialization activities we have underway as we look ahead to the planned Jelmyto launch. Jeff?
