Thanks, Sean, and thank you, Jenna, and thank you all for joining us this morning. I’d like to start the call by reminding everyone of the great progress we’ve made so far this year, including some highlights, which I’ll do in chronological order. In the first quarter, we announced the launch of our Phase 3 UNITY-CLL study, which is a large multinational Phase 3 study under special protocol assessment. Also in the first quarter, we solidified our patent portfolio by announcing the issuance of Composition and Matter Patents in the U.S. for both 1101 and 1202 providing protection through 2029 and 2033, respectively, exclusive of any patent term extensions. In May, we expanded our preclinical pipeline with the addition of a portfolio of BET inhibitors that we believe may be important to future combinations in non-Hodgkin's lymphoma, especially c-Myc-driven Diffuse Large B-Cell. In June, we presented data at ASCO and EHA which included safety and efficacy data from 165 patients treated with 1202 alone or in combination with TG-1101, the combination recall we refer to sometimes as TG-1303, and we’ve followed those patients for up to and beyond three years which demonstrated a unique and favorable safety profile for TGR-1202. Also in June, we were excited to announce we enrolled the first patient in our registration-directed UNITY Diffuse Large B-Cell Phase 2b clinical study evaluating TG-1101 and TGR-1202 as a combination compared to TGR-1202 as a single agent in patients with advanced relapsed/refractory Diffuse Large B-Cell. In August, we received orphan drug designation for TGR-1202 for the treatment of CLL and also orphan drug designation for TG-1101 for the treatment of neuromyelitis optica, NMO. In September, we presented clinical data from our first autoimmune study of TG-1101 in patients with NMO at the ECTRIMS conference with TG-1101 demonstrating a rapid and profound B-cell depletion with a single 450 milligram dose. In October, we were excited – although apparently we were the only ones excited to announce the revisions to the GENUINE Phase 3 clinical trial. With the modifications, we expect enrollment to be completed before year-end 2016 and top line data to be available in the first half of 2017. More recently, we announced a publication in blood describing a novel complementary mechanism of CK1 Epsilon inhibition by TGR-1202, which potentially offers a mechanism for the clinical activity of TGR-1202 observed in aggressive lymphomas. Based on that research, we’ve launched a Phase 1/2 study of TGR-1202 and carfilzomib in patients with relapsed or refractory lymphoma in collaboration with Columbia University Medical Center. And last but not least, we announced upcoming data presentations at the ASH meeting next month for TGR-1202 and TG-1101, which includes three oral presentations and three poster presentations. As you can see, we have been busy driving hard to achieving our 2016 goals and objectives. With that, I’d like to briefly touch on the recent amendment to the GENUINE trial as announced last month. Given the movement in the stock price following the announcement, I can only wonder if perhaps there was some misunderstanding regarding the changes and the impact on our registration pack for TG-1101. First, let me remind everyone of the two substantive changes that we made. First, Part II of the original GENUINE study was eliminated and accordingly the revised study’s sole primary endpoint is now overall response. And the second change was to reduce target enrollment to approximately 120 randomized patients. So why were these changes necessary and why are we excited about them? As we shared with investors starting as early in the year as January, we were facing enrollment challenges with GENUINE. By August, when we had our last quarterly conference call, we noted that GENUINE’s slow enrollment was diminishing its original purpose of a Phase 2 market strategy and indicated that all possible options are on the table for the study, including shutting down the study. So with the enrollment challenges as they were, we had two options. Shut down the program entirely or try to find an approval use for the data we could obtain. For us, we were very excited to be able to amend the protocol and still leave open the possibility to discuss the results with the FDA. Given the context of our FDA interactions, we believe the FDA could have taken a negative position regarding our ability to use the revised GENUINE study to support a BLA filing for accelerated approval. But they did not and they did agree that we could seek a pre-BLA meeting to discuss a filing for accelerated approval based on the results. Again, I think some shareholders misunderstood these interactions. Importantly, the revised GENUINE study still has a 90% power to show its statistically significant improvement in overall response with the minimal detectable absolute difference between the two arms of approximately 20%. Patients will be followed into a progression but this study will no longer be powered for PFS. We believe the expected data set from the revised GENUINE study is now in line with the overall response data sets provided to the FDA to support the first accelerated approval of ibrutinib, ublituximab and venetoclax, none of which were conducted pursuant through a special protocol assessment. Now with the amendments in place, we are projecting full enrollment in GENUINE to occur by the end of this year and we expect to have top line data available in the May-June timeframe of 2017. These changes put us back on track with our original enrollment guidance and also our expected to save us approximately $10 million over the next two years. I also want to note that the changes to the GENUINE study in no way affect the UNITY CLL trial, which is being conducted pursuant to a SPA. The UNITY CLL trial, as many of you know, is a randomized controlled clinical trial that is designed to support full approval for both TG-1101 and TGR-1202 with a potentially broad label for the treatment of both frontline and relapsed/refractory CLL. As mentioned, enrollment to the UNITY CLL study began in February of this year and we are pleased with the early enrollment trends observed to-date. We now have over 80 sites open for enrollment in the U.S. and we should have over 100 sites opened before the end of the year. We also recently began to open sites in Europe and believe we will enter 2017 with a full complement of worldwide sites up and running and fully engaged. We expect to see robust enrollment in 2017 building on the positive enrollment trends we are already seeing for the UNITY CLL study. I’d also like to highlight our UNITY Diffuse Large B-Cell registration-directed Phase 2b study evaluating TG-1101 in combination with TGR-1202, as well as TGR-1202 alone in patients with previously treated Diffuse Large B-Cell lymphoma. This study is being led by Dr. O’Connor at Columbia University Medical Center. The primary goal of this study is to access the efficacy as measured by overall response rate of the combination of 1303 as compared to 1202 alone with the goal of dropping the single agent 1202 arm after approximately 20 to 40 patients. Given the strong response it’s seeing in the recently released ASH Abstract for the combination of TG-1303 plus bendamustine, when the 1202 arm is complete; again, we’re hoping to drop that after approximately 20 to 40 patients, we plan to replace that arm with 1303 plus benda permitting us to compare 1303 to 1303 plus benda. Assuming a positive result after approximately 200 patients are enrolled, we would like to transition the study in a Phase 3 trial and ideally file 1303 alone and/or in combination with benda for accelerated approval. We are highly encouraged by the early data in Diffuse Large B-Cell from our Phase 1 and 2 studies for TGR-1202, TG-1303 and the 1303 plus benda triplet, and believe we are working toward an important new treatment option for patients with Diffuse Large B-Cell where there is currently no approved treatments for relapsed/refractory patients. With that, let me provide an update on our MS program. As many of you are aware, B-cell depletion therapy has already proven to be highly efficacious in treating relapsing and progressive forms of MS. Based on that data, earlier this year we launched our MS program with a Phase 2 study designed to find the optimal dosing regimen for TG-1101 in MS. In this study, we are evaluating B-cell depletion and other established MS efficacy endpoints as well as the overall safety profile of TG-1101 in MS patients and the safety and tolerability of accelerated dosing regimens designed to reduce infusion times. Enrollment is moving along nicely and we anticipate complete enrollment by year end in the pre-specified cohorts with expansion cohorts continuing to enroll into early next year. We plan to use the data from this Phase 2 study to commence a Phase 3 registration program in MS in the first half of 2017. We are highly confident from our experience on the cancer side and from early data from our ongoing NMO and MS studies that TG-1101 is a potent B-cell depleting agent. We have already begun communicating with the FDA and the EMA to understand their expectations for our Phase 3 program and we look forward to providing an update on this in the first half of next year. Having said that, we do believe given what we know about the efficacy of other anti CD 20 antibodies at MS that our Phase 3 program will be much smaller than the 1,600 plus patients in the ublituximab Phase 3 trials. Finally, I want to touch briefly on the upcoming ASH conference. With three oral presentations and three poster presentations, we are looking forward to a very positive conference. It’s worth noting that all of the clinical presentations include TGR-1202 in combination with other agents. We and investigators continue to believe that TGR-1202 is a best-in-class PI3K delta inhibitor, which based on its differentiated safety profile, can be safely combined with multiple agents; PI3K inhibitors, now JAK inhibitors, monoclonal antibodies and even chemotherapy whether in doublet or triplet combinations. We are very excited for the upcoming ASH conference and are looking forward to providing you with expanded data sets for each of the abstracts we’re seeing released last week. In addition to the formal ASH presentations, we will be hosting an investor reception with a distinguished panel of leading experts in CLL and NHL on Monday, December 5 at 8 p.m. at the Marriott Gaslamp in San Diego, California and we welcome and encourage all of you to join us. We are planning a great event this year and hope to provide attendees the opportunity to hear some fresh perspectives on TG-1101 and TGR-1202. Let me finish my prepared remarks by reminding everyone how far we’ve come toward achieving our goal of creating best-in-class combination therapies across a broad range of B-cell malignancies. With GENUINE expected to readout in the first half of next year and our UNITY program kicking into high gear, we believe we are on track to create significant value for our shareholders in 2017. And while pharmaceutical pricing controversies have damaged the entire industry and brought us down with it, unlike many other companies we see our value proposition rising as these concerns grow. With that, let me now turn the call over to the conference operator to begin the Q&A session, following which I will return to make some concluding remarks as well as reiterate our goals for the remainder of the year.
