Thank you, Jenna. And thanks everyone for joining us this morning. With the recent accelerated approval of UKONIQ, for the treatment of relapsed or refractory marginal Marginal Zone Lymphoma and Follicular Lymphoma, TG has transitioned into a full integrated commercial organization. We are extremely pleased to now have UKONIQ, the first and only dual inhibitor of PI3K-delta and CK1-epsilon available to patients. We see the approval of UKONIQ as the first step and our broader mission of developing novel treatment for patients with B-cell diseases. With successful Phase 3 studies in chronic lymphocytic leukemia refer to CLL and multiple sclerosis, MS, already completed and reported. We see the potential to positively impact, a significantly larger group patient on the horizon. Beyond that our pipeline has the potential to deliver novel combinations building up of a foundation of UKONIQ and ublituximab, our U2 combination that can further enhance outcomes for patient with B-cell diseases. Before I hand over the to our Chief Commercialization Officer, Adam Waldman to discuss the UKONIQ launch and preparations for the potential CLL and MS launches. I wanted to review some of our recent accomplishment as well as the current status of our ongoing programs. First and foremost as I mentioned at the outset of these depend remarks, in February, the FDA corrected accelerated approval of UKONIQ for the treatment of adult patients with relapsed or refractory marginal zone lymphoma, who have received at least one prior anti-CD20 base regimen and for adult patients with relapsed and refractory follicular lymphoma, who have received at least three prior lines of systemic therapy. This approval was primarily based on the results of the UKONIQ monotherapy cohorts of the UNITY-NHL Phase 2b trial. And the approval came just surely after the final results from the trial were presented at the American Society of Hematology Annual Conference, we refer to that as ASH in December 2020. Also note, within a month of approval these results were also published in the Journal of Clinical Oncology. The commercial team has been hard at work educating potential subscribers of UKONIQ and building a strong foundation which we believe will continue to translate into adoption of the UKONIQ and position us well for the plan CLL launch potentially later this year or early next. On that note, as most of you know, we presented positive results from the UNITY-CLL Phase 3 trial at the ASH Annual Meeting in December. And more recently, at the end of March, we announced the completion of a rolling submission of a Biologics License Application, referred to as a DLA to the US FDA, requesting approval of ublituximab, our investigational glycoengineered, anti CD20 monoclonal antibody in combination with UKONIQ. The combination as many of you know referred to as U2, as a treatment for patients with chronic lymphocytic leukemia. This BLA submission was based primarily on the results of the UNI-CLL trial, which was conducted under special protocol assessment. And as a reminder, the FDA previously granted Fast Track designation to the U2 combination for the treatment of adult patients with chronic lymphocytic leukemia and orphan drug designation for the U2 combination for the treatment of CLL. The next step is we expect to hear from the FDA later this month on whether they have accepted the submission for filing. With approximately 185,000 Americans living with CLL and approximately 40,000 patients seeking treatment annually, CLL remains an incurable disease and represents a large patient population where we believe U2 will provide a needed treatment option for these patients. Now, I'd like to turn to our MS program, where our BLA submission is slated for the third quarter of this year. That BLA will be supported by the positive results from our ultimate 1 and 2 Phase 3 trials, evaluating ublituximab and relapsing forms of MS, which were presented during the AAN conference last month. Both studies met their primary endpoint with ublituximab treatment, demonstrating a statistically significant reduction in annualized relapse rate, which we call ARR annualized relapse rate over a 96-week period with a P-value of less than 0.005 in both the trials, that's compared to teriflunomide. And when you look ublituximab treatment resulted in ARR of 0.076 and Ultimate I and .091 in ULTIMATE II. For those who were on the call with the experts, which are talking about momentarily, they were very excited to see that those ARR numbers were below point one, which is never occurred before in a Phase 3 trial. So really excited about those results. We also hit key secondary MRI endpoints, including statistically significant reductions in both T1 Gd-enhancing lesions, as well as T2 lesions. Ublituximab also reduced disability progression and increased the rate of disability improvement as compared to teriflunomide. However, the former was not statistically significant. In addition to the presentation AAN, we hosted a call with leading neurologists, to review this data, and the replay of that call is available on our website. And I do encourage folks who are interested in TG, to have a listen to that call. The doctors on the call were very enthusiastic about the profile of ublituximab, and its potential in the treatment of MS. For our part, we are extremely pleased with the results from the ULTIMATE I and II trials. And believe these data showcase the potential of ublituximab and to provide a highly efficacious treatment option with a generally well tolerated safety profile. If approved, ublituximab will be the only CD20 offered in a convenient one-hour infusion every six months, of course following the first infusion, which treating physicians have shared as an important benefit for them and their patients. As a reminder, this trial was also conducted under special protocol assessment with the FDA. And as noted earlier, we are targeting a BLA submission for o ublituximab to treat patients with relapsing forms of multiple sclerosis in the third quarter of this year. The last topic I want to cover before turn the call over to Adam is our U2 plus Venetoclax program and our U2 plus 1701 program. As reminder 1701 is our internal BTK inhibitor. We view both of these programs to be an important part of the growth strategy for U2 and CLL. For the U2 plus venetoclax program, we have the Phase 1 study led by Dr. Paul Barr, Professor of Medicine and Director of the Clinical trials office for the Wilmot Cancer Center in Rochester, New York. Preliminary results from the first 27 patients in this study to complete 12 cycles of fixed duration therapy were presented at ASH this past December. In those patients, there was 100% overall response rate, and greater than 75% of those patients achieved undetectable minimal residual disease in the bone marrow. To my knowledge, that is the best reported rate of undetectable minimal residual disease in the bone marrow to-date in patients with relapsed refractory CLL. Later this year, we should have almost two times as many patients to report on through 12 cycles of treatment. So hopefully that will be something we were able to present at ASH this year. Now that Phase 1, set the foundation for Ultra-V Phase 2/3 trial, which is evaluate in the combination of U2 plus venetoclax in patients with both treatment naive CLL, as well as relapsed or refractory CLL. The Phase 2 portion of the Ultra-V trial completed enrollment with approximately 165 patients being enrolled in just 16 months. The Phase 3 portion is now open to enrollment, and there's a multicenter randomized trial, comparing you to plus venetoclax to an active control arm of U2. This trial is being led by Dr. Richard Furman, who is the Director of CLL Research Center at the Weill Cornell Medicine. We are excited about this combination and believe it can potentially offer patients a very active treatment that is of limited duration. Finally, I mentioned that our BTK inhibitor TG-1701 continues to impress us. We reported preliminary data at ASH and we'll provide another update in the coming weeks at ASCO. Our goal is to explore the potential combination of UKONIQ and U2 with 1701 to offer the benefits of the triple inhibition of BTK, PI3K and CK1 Epsilon, which would be the first of its kind. And putting them together, but also dialing down the known toxicities of each of those classes. Again, this would be a very novel first in class product. As you can see, significant progress has been made across all of our pivotal programs, setting us up for an exciting remainder of 2021 and hopefully even more impactful 2022 with the potential of expanding our commercialization efforts into CLL and MS. With that, I'm excited to turn the call over to our Chief Commercialization Officer, Adam Waldman to share some highlights from our early commercialization efforts of UKONIQ.
