Thank you, Jim. Good morning, and thank you very much for joining us. Over the last quarter, we have made significant progress in advancing our pipeline. Our tasimelteon clinical program in Non-24, for totally blind patients, is nearing completion. Both of our Phase III studies are now fully enrolled. The SET study has enrolled 84 patients, and we expect to report top line results by the end of 2012. The RESET study has enrolled 20 patients, and we expect it to report top line results in the first quarter of 2015. Non-24-Hour Disorder in the blind is a serious condition, which affects 50% to 70% of blind individuals with no light perception. The ability of the eye to perceive light has 2 functions. One is to form images and the other is to reset the master body clock through its impact on the suprachiasmatic nucleus, or SCN. It is the absence of the circadian body clock resetting function that is definitional for Non-24. And it is this circadian body clock resetting function that we aim to restore with tasimelteon. In our Phase III studies, we're evaluating the ability of tasimelteon to reset the master body clock and synchronize the circadian rhythm of blind patients suffering from Non-24 to 24 hours and also measures the impact of this resetting activity on measures of the sleep wake cycle. Specifically, the SET study is a double-masked randomized study in 84 individuals with Non-24. Patients are randomized one-on-one on tasimelteon 20 milligrams or placebo. The primary endpoint of this study is entrainment, which reflects a resetting of the body clock. This is measured by the proportion of patients who demonstrate entrainment of their alpha-sulfatoxymelatonin rhythm, or alpha MT6, by each treatment. A strip-down endpoint is response, measured by the proportion of patients who are both entrained and have a clinically meaningful improvement in at least one parameter of the sleep-wake cycle. These parameters include measures of total nighttime sleep, total daytime nap time, weighted timing of sleep and clinical global impression scale. We're also evaluating a number of secondary endpoints, including entrainment of the cortisol rhythm. It is worth noting that we have recently reported that tasimelteon was shown to entrain the cortisol rhythm as well as the alpha MT6 rhythm in Non-24 patients during the open-label screening phase of the RESET study. We believe this observation is significant, as it suggests that tasimelteon's circadian and training properties are due to a resetting of the master body clock at the site of the suprachiasmatic nucleus, and therefore, we expect it to affect all peripheral circadian activities, which include the sleep-wake cycle, core body temperature and cardiovascular, metabolic and hormonal homeostasis. The top line results of the SET study, which we expect to report by the end of 2012, will include outcomes of many of these endpoints. The RESET study is a double-masked randomized study in 20 patients with Non-24. The design includes an often label screening portion, which identifies people who are entrained on tasimelteon, followed by a randomized portion on tasimelteon and placebo. The primary endpoint of the RESET study is the maintenance of entrainment measured by the proportion of patients who remain entrained to a 24-hour alpha MT6 rhythm on each treatment. It is expected that patients randomized to placebo will be enabled to maintain entrainment, while patients randomized on tasimelteon will be able to maintain their entrained status. Additional endpoints in the RESET study include the maintenance of entrainment measured by entrainment of the cortisol rhythm. We expect to report top line results of the RESET study in the first quarter of 2013. We are in continuing discussions with the Food and Drug Administration and expect to hold a pre-NDA meeting in the first quarter of 2013 to confirm the path towards the goal of a projected mid-2013 NDA filing. If the FDA approves this planned NDA for Non-24, we believe that tasimelteon will become the first circadian regulator to be approved for the treatment of any circadian disorder. As such, we believe that it will represent a significant value for our patients and a substantial commercial opportunity for Vanda. Non-24 affects an estimated 65,000 to 95,000 patients in the U.S., although the awareness is extremely low. We believe this lack of awareness of the condition results from underdiagnosis in the absence of an effective treatment. While this is a hurdle, we believe it also represents a significant market opportunity for Vanda. As Bob Repella, our Chief Commercial Officer, will discuss in a few minutes, we're currently undertaking a number of activities designed to address these issues and prepare for a potential commercial launch. We're also evaluating tasimelteon for the treatment of major depression. Our Phase IIb/III MAGELLAN study of 500 patients with Major Depressive Disorder in the U.S. is now fully enrolled. Many lines of evidence have suggested a connection between circadian function and mood disorders. It is our hypothesis that tasimelteon, through its circadian regulatory activity, may be able to affect central nervous system pathways that are responsible for certain of the symptoms of major depression. In the MAGELLAN study, we're evaluating the ability of tasimelteon to improve the symptoms of major depression as a monotherapy measured by improvements in the Hamilton Depression and MADRS depression scales. Secondary endpoints of this study include measures of sleep improvements, measured with the LSEQ scale, as well as exploratory analysis of circadian function via salivary melatonin measurements. Major depression is a common and well-recognized disorder that affects millions of patients worldwide. Despite the availability of a number of antidepressant treatments, 2/3 of the patients report residual symptoms, which suggests that new therapeutic modalities are needed. If successful, tasimelteon could become the first circadian regulator in the U.S. to demonstrate antidepressant properties. Agomelatine, a dual melatonin agonist, is approved in the EU for the treatment of major depression. Top line results of the MAGELLAN study are currently expected to be reported in the first quarter of 2015. I will now turn to Fanapt, iloperidone, our FDA approved antipsychotic product marketed by Novartis in the U.S. Vanda receives royalties from Novartis on net sales of Fanapt, as reported in our earnings release. We have recently reported that Novartis had decided to discontinue development of the long-acting injectable or depot formulation of iloperidone. We're currently in discussions with Novartis to determine next steps. We reported earlier in the year that Fanapt was approved for marketing in Israel, and we are happy to report today that our Argentinian partner has informed us that Fanapt has also gained marketing approval in Argentina. In the EU, FANAPTUM, the trade name of Fanapt in Europe, is currently under review by the EMA and we expect a CHMP opinion within the next few months. We are also making progress with the development of our Neurokinin-1 Receptor antagonist, VLY-686, which we recently acquired from Lilly. We are now in the process of completing technology transfer and evaluating a number of possible indications for proof of concept evaluation, including pruritus in patients with a topic dermatitis and chemotherapy-induced pruritus. We believe that these indications represent significant unmet medical needs for which the VLY-686 may be uniquely suited to address through its mechanism of action. We expect that we will be prepared to initiate a clinical development program for VLY-686 in the second half of 2015. I will now turn the call to our Chief Commercial Officer, Bob Repella, who will now provide an update on our market development efforts in support of tasimelteon for Non-24-Hour Disorder. Bob?
