Thanks Kevin and thanks for the participants who are joining the call this afternoon. Let me start with elagolix, Kevin mentioned the recent meeting between Neurocrine and AbbVie and indeed now that the two Phase III endometriosis trials have completed the on treatment portion of the studies and the results have been shared with the Neurocrine team. We’re really happy with what we see, these confirm what AbbVie has already released namely the efficacy and safety results that are very conducive for product like this moving forward it is hard to understanding they have a fairly expensive publication plan in place and in fact I think for those who are interested at the upcoming American Society Of Reproductive Medicine, the ASRM meetings that are coming up in Atlanta, sorry Salt Lake City later this year they should be having extensive amount of data for their clinical trials with elagolix. So good progress, on track, we’re very lucky to have them as a partner and look forward to additional data to become available. Our next program to talk about is congenital adrenal hyperplasia program as we've discussed in the past, we had nice proof of concept with our initial 860 molecule, we had finding in juvenile toxicology study that we conducted which led us to elect to take a follow on molecule forward that doesn't have that finding. And we are working intently to have all the materials ready for new IND filing later this year. So that is moving along as scheduled. Third program to talk about is the essential tremor program, we successfully completed the single ascending dose Phase I study in healthy volunteers earlier this year, very pleased with what we got from that mainly the safety and PK data that we are interested in and that has allowed us to move on to the next study which is Phase I multiple ascending dose trial in healthy volunteers that study queued up at the start in the near future and the information from that trial will let us make a determination about doing into a trial in patients with the central tremor as the next study after that. So, that’s on track obviously the next piece of information from that study would be about our impression of the safety and tolerability in PK after repeated dosing of the molecule and then our interactions with the FDA going into the next studies. We have been continuing to work with our colleagues in consulting in the field of tremor and have tremendous enthusiasm from talking to them, they are very eager to get a new molecule into the clinic to help the 8 to 10 million people in the US with ET, so eager to keep that going forward. So let’s move on now to the main focus of our work, keeps all of us busy and very excited that is valbenazine program, we've made some considerable strides over the last few months by far and away as Kevin pointed out and Tim emphasized the overwhelming focus of work at every one here at Neurocrine and some of our consultants and vendors have been the NDA preparation and submission plan, it is the primary focus, we are on track and very pleased with the progress that we are making with this submission. Now, I felt that it might be useful to do as to walk through kind of the scope of some of the studies that contribute to the NDA. So I'll talk about a range of activities we’ve conducted over 20 clinical trials with valbenazine across Phase I, Phase II and Phase III and this is a very robust collection of data for safety and efficacy. The phase I study is of course are the fairly classical ones that you would do, I would emphasize that more recently we have completed some of the special types of phase I studies that one does for an NDA. So for example, a phase I study of valbenazine in subjects with no existing emphatic impairment dosed with valbenazine this helps us understand dosing metabolism and exposure and people with liver disease and this kind of data then helps the FDA Neurocrine determine dosing and people that kind of disease. We have completed a number of phase I drug interaction studies, all of these have been designed either to look at the impact of valbenazine on concomitant medication with the known enzyme dependence or vice versa, the effect of concomitant medication on valbenazine exposure and clearance and those have been completed successfully. We've also completed our phase I study on cardiac repolarization this was using supra-therapeutic doses of valbenazine in healthy volunteers and the study confirmed what we have pointed out at earlier times namely in our early phase I studies we see a slightly positive slope for the relationship of plasma concentration and QTCF. This translate into about a 3 millisecond QTCF change on 80 milligram dose. We've also confirmed that there is no clinically significant effect on QTCF in our phase II and phase III studies, we have done an extensive analysis of ECG data collected in triplicate on patients that are on long-term clinical trials as well as the placebo controlled portion of these trials and very satisfied with the output of that analysis. Talking about KINECT 3, I’ll mention the - as we speak the last subject is completing their last study visit for the KINECT 3 trial. We are very grateful to the patients obviously the caregivers, the investigators and the coordinators who have helped make this study a reality. There is no president really for this kind of large sponsor driven well controlled registration trial for TD historically, so it was - it’s really been a effort on many people's part and we’re very grateful for everything the team has done. Obviously this data is key and as I'll mention in a moment we hope to share some of this long-term efficacy and safety data in upcoming scientific meetings later this year. The KINECT 4 study is a one your open-label safety study in patients with tardive dyskinesia as you may be aware of the enrolment for the study closed earlier this year, patients will continue - the subjects will continue in this trial throughout the year this is not a rate limiting gatekeeping step for NDA submission this is something that can continue to run even after NDA submission. Now, with KINECT 3 and KINECT 4 studies, although they were up to one year duration, we continue to have requests from investigators and from subjects and caregivers that subjects be given an opportunity to have continued access to valbenazine so we set up the study that we called the rollover study if you look on clinicaltrials.gov it's NBI-98854-1506, this was a really good opportunity not only to help patients of course but to continue to gather additional safety data over extended periods of time. So it's conceivable that patients will have access to valbenazine up until the time of product launch, [indiscernible] it gets approved as planned. So that study is going well and subjects will continue to have an opportunity to involve in that study up until the time of approval. Obviously all of the data that comes from these phase I and phase II and phase III studies is incorporated into the NDA and I know people often ask me what's the label going to look like and what is the dosing language and the risk language and all that obviously has to come from the review process with the FDA, recall that we do have a breakthrough therapy designation, we have had considerable discussion and interactions with this psychiatric revision at the FDA that process of communication has been going quite well but at the end of the day it comes down to their review of the entice safety and efficacy package as to whether the drug not only gets approved but what language goes in the label, so we’ll need to wait and see how that unfolds. Obviously in parallel to the tardive dyskinesia effort is our Tourette syndrome program and we have the two ongoing placebo-controlled phase II trials the T-Force study also known as the 1505 study in adults with Tourette and the T-Force GREEN study the 1501 study those are about going well very happy a little surprised that the adult study was recruiting a little faster than I thought it would that's going well so we should have data - topline data by end of the year if things continue to go well for that study. And for the T-Force GREEN study we’re continuing to bring on the sites that we had identified, so we're not quite complete in getting them all up and running due to some of the challenges and working with academic institutions and local IRBs. But that is going well, recruiting is going well, I'm very happy with the characteristics of the kids with TS that are joining this study as well as the adults. They have moderate to severe Tourette Syndrome based on the Global Tic Severity Scale they are very appropriate candidates for these clinical trials. And so far, we’re very pleased with the safety and tolerability of enrolment in these studies. That T-Force GREEN study we would expect topline data sometime around turn of the year depending on how the rest of recruitment goes. Now, we also got feedback from the Tourette investigators, Tourette Syndrome subjects and their caregivers, families that they wanted to access to valbenazine after participating in placebo-controlled trial so we designed and have just now implemented the 1601 study called T-Fusion and I think this was in our press release last week and should pop on clinicaltrials.gov shortly we don't control when it gets posted but it should be sometimes in the next few days I would think if you want some more details. This is an extension study for children or adults with Tourette that have been completed the T-Force or the T-Force screen study they can roll over into the T-Fusion study as an extension trial and so we're really happy about that as our investigators and subjects. So, that's the summary of the valbenazine clinical trial activity. It’s worth also pointing out as Kevin mentioned the medical affairs group has been very busy, our field based MSLs have been calling on scientific leaders throughout the country getting learning from them kind of what’s the state-of-the-art of what's happening in TD diagnosis and then management they have been sharing the information from the what’s been published about valbenazine from our recent publications as well as the recent presentations that the American Academy of Neurology, American Psychiatric Association and the Movement Disorder Society we've also submitted I should mention or in the process of submitting some additional presentations that we hope will be accepted for upcoming scientific meetings later in the second half of this year, these are presentations regarding long-term efficacy of valbenazine, long-term safety of valbenazine and additional work on pharmacology and pharmacokinetics so some, a rich of trove of information that is being prepared for public dissemination. So, they will continue to work, the medical affairs team is quite busy for MSLs publication, health economics and outcomes and a variety of other activities. Well, I think probably what I should do is stop there Kevin and…
