Thank you very much, Kevin and good afternoon everyone. Thank you for joining us to discuss Vanda's fourth quarter and full year 2023 results. I will briefly discuss key updates and then I will ask our General Counsel, Tim Williams, to provide a brief update on litigation measures, before turning the call over to Kevin Moran to discuss our financial results. We have significantly advanced our development pipeline now with three PDUFA action dates in 2024, including our supplemental new drug application or sNDA for bipolar I disorder in adults with a PDUFA date in April of 2024 and our New Drug Application, or NDA, for gastroparesis with a PDUFA date in September 2024. On our supplemental NDA for HETLIOZ in the treatment of insomnia, as we previously communicated this week, our sNDA was accepted for filing and is under review by the FDA with a PDUFA target action date of March 4, 2024. Earlier this week, we announced that we had received a notification from the FDA stating that the FDA has identified deficiencies that preclude discussion of labeling and post-marketing requirements and commitments at this time. No deficiencies were disclosed by the FDA in the notification, and the FDA stated that the notification does not reflect a final decision on the information on the review. However, frequently, such a communication from the FDA is followed by a complete response letter. Subsequent to that development on February 6, 2024, a Vanda filed suit in the US District Court for the District of Colombia, challenging the FDA's conduct in reviewing the insomnia sNDA. Vanda is asking the District Court to compel the FDA to adhere to the legally mandated 180-day review period for sNDAs and to declare as unlawful and void the regulations the FDA relies upon to issue complete response letters. On Fanapt, for bipolar I disorder, as previously discussed in December of 2022, we announced positive results in our Phase III clinical study of Fanapt in acute manic and mixed episodes with bipolar I disorder in adults. Our supplemental NDA for Fanapt in bipolar I disorder in adults has been accepted for filing by the FDA, and the target action date has been set is April 2, 2024. We believe that this potential label expansion represents a significant opportunity for the Fanapt franchise given the high prevalence of bipolar disorder in the United States. The estimated prevalence of bipolar disorder in the US adult population is multiple times larger than the estimated prevalence of schizophrenia. Additionally, on tradipitant for patients with gastroparesis, our new drug application has also been accepted for filing by the FDA, and the target action date has been set as September 18, 2024. The FDA package supported by the results from clinic electrical studies 2301 and 3301, which we believe demonstrate substantial evidence of efficacy after tradipitant in this indication as well as a safety database to support the tolerability of this drug. The expanded access program continues with multiple patients have been treated for at least six months and the longest-treated patient for more than three years. We're pleased with our revenue performance despite the challenges of the at-risk launches of generic catalyst products. Over the course of this year, we have taken a number of actions intended to position the commercial business for continued success, both with respect to existing products and indications as well as potential future products and indications. These include preparations for the potential near-term expansion of the Fanapt franchise, if we receive FDA approval for bipolar I disorder accounts. During the fourth quarter of 2023, we completed a transformative acquisition as we obtained the US and Canadian rights to PONVORY, ponesimod from Actelion Pharmaceuticals Limited, a Johnson & Johnson Company for US$100 million. PONVORY is a once-a-day oral selective sphingosine-1- phosphate receptor 1 modulator, approved by the FDA and Health Canada to treat adults with relapsing forms of multiple sclerosis. Additionally, PONVORY is a potential therapeutic candidate for the treatment of a diverse group of inflammatory and autoimmune disorders ranging from psoriasis to ulcerative colitis. Most recently, the US Patent and d Trademark Office issued a notes of allowance for PONVORY patent application 17/962, 968, which when issued, is anticipated to expire on October 10, 2042. On the clinical side, as previously reported, in May of last year, we announced positive results from the first Phase III study of tradipitant in the treatment of motion sickness. And subsequent to that, we initiated a second Phase III study, which is now already 50% enrolled. We plan to pursue FDA approval of tradipitant for motion sickness upon completion of the clinical development program. And outside of this update on the tradipitant motion sickness program we’ll continue to progress our robust clinical development pipeline, which includes multiple products across a wide range of therapeutic areas. With that, I will now ask Tim Williams, our General Counsel, to provide a brief update on litigation matters. Tim?
