Thank you, Jim. Good morning, and thank you very much for joining us. Over the last quarter, we have made significant progress in the clinical development of tasimelteon for both Non-24 Disorder and major depression. For Non-24, we have now fully enrolled the larger clinical Phase III, S-E-T, SET study, a double-masked, placebo-controlled, 2-arm study. In that study, we have enrolled 84 individuals who are totally blind, with no light perception. During this screening phase, we determined that their biological reason is not contained to the 24-hour clock. This is accomplished via measurement of the urinary melatonin metabolite. The 84 patients were enrolled across multiple clinical sites in the U.S. and Germany during the 2-year span. The SET study is designed to determine the ability of tasimelteon to align the body clock to a 24-hour rhythm towards the endpoint, which is referred to in the scientific literature as entrainment. Unlike all entrainment, it's definitional for Non-24-Hour Disorder. We and key opinion leaders believe that a treatment of entraiment is the appropriate endpoint for any therapeutic modality aimed at affectively addressing the disorder. It is our hypothesis that tasimelteon will be able to restore the physiological process of resetting the body clock to a 24-hour rhythm in these patients to who lack light perception, and consequently, the likely ability of naturally resetting the body clock. Proof of mechanism has already been demonstrated during the screening phase of the RESET study. In addition to the primary endpoint of entrainment, we are also collecting daily data on nighttime sleep and daytime naps, including the duration and timing of each episode. These data will inform our secondary clinical endpoints of improvement in nighttime sleep and daytime naps. Since it is apparent that the aberrant sleep patterns currently have a periodic nature given the perpetual system of the body clock relative to the 24-hour clock, we are likely to define that the secondary endpoint the improvement in the worst quartile of sleep during the observation period. We're also collecting data of overall clinical impression, which will inform the CGI improvement endpoints. For the RESET studies we enrolled, we expect to report top line results of this study by the end of 2012. Our second Phase III study, the RESET, continues to enroll, and we expect to fully enroll that study in the next few months and report top line results in the first quarter of 2013. In the RESET study, patients receive tasimelteon during the screening phase, and those patients that are successfully maintained by tasimelteon to a 24-hour clock are randomized to either tasimelteon or placebo. It is our hypothesis that the highest proportion of patients in tasimelteon will continue to be entrained after randomization as compared to the placebo-treated patients. We're also collecting sleep data in the same fashion that we'll describe in the SET study. The results of the 2 studies will form the body of evidence of effectiveness by which we expect to seek FDA regulatory approval. While we have not reached an agreement with the FDA on the endpoints of these studies, we and key opinion leaders from around the world's believe that the design and endpoints of the current studies, if successful, will provide convincing and definitive proof of the effectiveness of tasimelteon in Non-24. We will continue to pursue available means in order to further clarify the regulatory path in the most exceeding manner as we advance towards our goal of a projected mid-2013 NDA filing with the FDA. On major depression, the MAGELLAN study of tasimelteon in patients with MDD, Major Depressive Disorder, continues to enroll towards a goal of 500 patients from multiple U.S. sites. Based on the current enrollment rate, we expect that we will report top line results in the first half of 2013. This is a 2-arm placebo-controlled study with tasimelteon as a monotherapy in MDD, and the primary endpoints are the typical HAMD and MADRS depression scales. We're also collecting data on sleep, as well as circadian function. We continued the technology project from Eli Lilly on the recently acquired Neurokinin-1 Receptor antagonist, VLY-686. VLY-686 could have utility across a number of potential indications in the way of exploring clinical development options at this time. On Fanapt, I would like to provide you with an update on our EMA application. We have received the Day 180 List of Outstanding Issues, and we have already had a meeting with their representative country to further clarify these items. The major outstanding issues centered around competitive efficacy, cardiac safety and appropriateness of the existing active control maintenance study. We're currently considering our strategy and have requested and expect to be granted an extension to respond to the outstanding issues in the fourth quarter of this year. Bob Repella, our Chief Commercial Officer, will provide an update on our market development efforts in support of tasimelteon for Non-24-Hour Disorder. Bob?
