Great. Thanks, John and good morning everybody. The third quarter of 2015 was an exciting time for us as we were able to check off some additional key milestones from our list of goals for 2015 obtaining a Special Protocol Assessment for our UNITY-CLL trial, in patients with front-line as well as relapsed/refractory CLL, it was an extremely important and exciting milestone for us as it represents our first pivotal trial for the combination of TG-1101 plus TGR-1202 what we call TG-1303 or simply 1303. If successful, this trial should provide 1303 with a broad approval in CLL offering patients in both front-line and relapsed/refractory setting, a novel, chemo free treatment option. It also will allow us to use 1303 as a base for future triple and possibly quad combination therapies. Another important achievement for the quarter was the initiation of a Phase 1/2 study evaluating the use of TG-1101 plus TGR-1202, plus pembrolizumab, the anti-PD-1 immune checkpoint inhibitor, in relapsed/refractory CLL patients. This study marks the first clinical trial evaluating the safety and tolerability of combining a PI3K delta, an anti-CD20 monoclonal antibody and an anti-PD-1 checkpoint inhibitor as we continue to break new ground and lead the field in novel combinations. We are excited about the progress we made during the third quarter and have been working tirelessly towards accomplishing remaining goals on our 2015 list. With the two phase 3 programs established in CLL, we are looking forward to expanding our registration program into Non-Hodgkin's lymphoma as soon as possible. Before taking a deeper look into our oncology programs and the upcoming ASH presentations, I wanted to briefly touch on an area I think will start to capture broader investor interest next year and manage [ph] our expansion into autoimmune disease, an area where B-cell targeted therapies have proven to be highly efficacious. Our goal is to launch our first trial in Multiple Sclerosis in the near-term. I won’t say in much more today on the autoimmune applications in terms of strategy or trial design but investors should get ready as the next year this area can really heat upcross. I will say since Roche announced their successful Phase 3 study for their anti-CD20 monoclonal antibody NMS and Novartis paid almost $1 billion in upfront of milestone payments for obinutuzumab we have seen considerable interest in our B-cell targeting agents from larger players in the space. We plan to move forward in autoimmune as aggressively as we move to the oncology programs and believe it may be possible to launch a phase 3 trial late next year. Moving back to oncology, I’d like to start by reviewing our current phase 3 programs. First, the GENUINE Phase 3 trial which is evaluating TG-1101 in combination with ibrutinib, in patients with high risk chronic lymphocytic leukaemia, or CLL which now has nearly 140 sites participating in the study. Enrolment into this trial is of the utmost importance to us and the number of sites we’ve been able to bring on board is a great accomplishment and a testament to the appeal of the 1101 or ibrutinib regimen among clinicians. Enrolment is moving along on pace and we are still targeting to complete enrolment into this study and analyze the overall response end point by the end of 2016. Moving along to our recently announced UNITY-CLL study, this is a phase 3 clinical trial of TG-1101 plus TGR-1202 or again referred to as a 1303 combination in front-line and previously treated patients with CLL which is also being run for CMC and SPA. The basis study design is a randomized controlled clinical trial that includes two key objectives. First, to demonstrate the contribution in each agent in the 1303 regimen and second to demonstrate superiority in progression free survival over the standard care to support for submission for full approval of the combination. The study will randomize patients with the four treatment arms 1101, plus 1202 or 1303, 1101 alone, 1202 alone and an active control on obinutuzumab which is commercially known as Gazyva plus chlorambucil. In each interim analysis, we’ll access contribution of each single agent in the 1303 combination regimen and which if successful will allow early termination of both single agent owners, a second interim analysis will be conducted on total enrolment into the study which if positive we plan to utilize for accelerated approval assuming an early termination of the 1101 and 1202 single agent arms the study will enrol approximately 450 patients. This study is being led by Dr. John Gribben, Professor of Medicine and the Gordon Hamilton Fairley Chair of Medical Oncology at St. Bartholomew's Hospital, at the Barts Cancer Institute in London, England. As mentioned earlier, we are very excited about this study and the related SPA. If successful, this trial should lead to a very broad label in the treatment of CLL and position 1303 as a backbone for further proprietary combination therapies as it continues to drive for better patient outcomes and ideally for secure [ph]. Now, let me read some of the data continued in our ASH abstracts, which were released last week. Please be aware that the ASH abstracts were submitted only about two months after our ASCO and Lugano presentations and thus do not contain all the patient data that will be presented at ASH. Turning to the abstracts, which I’ll review in the order in which they will be presented. The first presentation which will occur during the Saturday post recession will be an update to the 1101 plus 1202 combination or our 1303 study. Some highlights from this abstract include of the 56 patients enrolled in evaluable for safety, the only grade 3 for adverse events reported in greater than 5% of patients was Neutropenia. On the efficacy side, of the 37 evaluable patients treated at the higher doses of TGR-1202, five or seven patients with CLL, SLL responded to treatment. Of the two patients not responding, one patient remains on study as a stable disease creating further assessment and the other patient ibrutinib refractory 70p delete [ph] patients achieved stable disease that eventually progressed. We’ve also seen a high level of activity in Indulin [ph] lymphomas and diffused large B-cell lymphomas including 16 responses out of 28 patients which includes a Richter's patient that responded to the combination. The next presentation will be during the Sunday post recession and will give the combination of 1202 plus obinutuzumab and chlorambucil. This is an interesting study, which was designed as a backup registration strategy and we’ve been unable to establish a regulatory pathway for 1303 which now has been accomplished for the UNITY-CLL study. Nevertheless, we believe this study provides you interesting data points and helps in foremost about what we may expect to see in the front line setting with 1303. Some highlights from the abstracts include, of the 14 valuable frontline patients, 13 or 14 responded with the remaining patient exhibiting a 48% reduction in the novel size and a further efficacy assessment. Of these frontline patients 43% were MRG negative following treatment. Interestingly, there were only three previously treated patients on this study, all three would be [Indiscernible] of which two or three responded to the combination with the third patient experiencing a significant no reduction ending further assessments. Moving to Monday, we will have three additional presentations. The first is for the combination of 1101 plus ibrutinib in patients with mantle cell lymphoma. As you may recall, this is the second cohort of the 1101 plus ibrutinib study for which we’ve previously reported results for CLL patients. Some highlights from this abstract include of the 15 evaluable patients 87% responded with 33% out of 15 having a complete response. This compares very favourably to the ibrutinib label that showed a 66% overall response rate with just 17% complete responses. We believe these data further confirm the activity seen in the CLL cohort with the 1101 plus ibrutinib combination where we see higher response rate in deeper responses by adding 1101 on top of ibrutinib and this gives us additional confidence in the possible positive outcome for GENUINE Phase 3 study. The next presentation during Monday’s post recession will be an update to our single agent TGR-1202 Phase 1 study. Highlights from this abstract include of the 75 patients with a variety of relapsed refractory B-cell malignancies treated with single agent TGR-1202 no grade 3 or greater AEs were observed in greater than 10% of the patients. Notably with single agent 1202 hepatic toxicity remains limited and we have yet to observe a case of colitis with some patients now on this study for over two and a half years. From an efficacy standpoint, 94% or 15 of 16 of the CLL patients achieved a notable response including 63% that have a true partial response by the Hallek criteria. In the Indolent NHL cohort, of the 16 evaluable patients, 14 or 88% have achieved reductions in tumor [ph] burden with six patients on study for over 12 cycles which is approximately 12 months and some patients on therapy over two years with five of 12 follicular patients achieving an objective response with many still on study pending further efficacy assessments. Finally, TGR-1202 demonstrated activities of diffused large B-cell as a single agent with three of eleven evaluable patients responding to therapies. And last, but not least on Monday Dr. Dang [ph] from Columbia University will give an oral presentation for some very exciting preclinical work which identified a novel mechanism of action with TGR-1202 as distinguished from other PI3K delta inhibitors. Through this new mechanism, TGR-1202 synergised with Brentuximab [ph] the produce inhibitor [Indiscernible] now AMGEN to the previously very challenging target. This research could have important implications in the treatment of aggressive lymphomas and potentially from solid tumors. We are very excited for the upcoming ASH conference and are looking forward to providing you with extended data sets for the abstracts we just reviewed. We will also be hosting an investor reception with the distinguished panel of leading experts in CLL and NHL on Monday December 07, at 7:45 PM at the Hyatt Regency in Orlando, Florida. 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 perspective. As always, this event will be live webcast on our website at www.tgtherapeutics.com and for those of you who cannot listen into the live event, a replay will also be available on our website. With that, I’d like to wrap up today’s call by reviewing the key golden objectives remaining for 2015. We will continuously aggressively recruit into the GENUINE Phase 3 clinical trial of 1101 in combination with ibrutinib with the goal of completing enrolment and analyzing the overall response endpoint in the second half of next year. We look forward to enrolling the first patient by year and our UNITY-CLL Phase 3 clinical trial of the combination of 1303 and front line and relapsed/refractory CLL, our second Phase 3 clinical program under SPA. We also hope to announce our next registration file, evaluating 1303 in patients with NHL. We will continue to recruit into a triple combination cohort of 1303 plus ibrutinib as well as the triple combination study of 1303 plus pembrolizumab as well as seek to evaluate additional novel triple combinations of interest. We look forward to expanding into auto immune disease with diverse trial, a Phase 3 trial on Multiple Sclerosis to start in the near future. We will continue to advance our preclinical compounds including IRAK4, anti-PD-L1 and anti-GITR in the clinic and towards clinical development as an update we had hoped to have IRAK4 in the clinic before yearend, however we are still reviewing the two lead candidate and we are now targeting the first half of next year. And finally, we will continue to seek additional drug candidates to further compliment our current portfolio. With that, let me turn the call back over to the conference operator to begin the Q&A session, following which I will return to make some concluding remarks.
