Thank you very much Kevin. Good afternoon, everyone. Thank you for joining us today to discuss Vanda's first quarter 2022 results. We believe 2022 is going to be an exciting year for the company, as we strengthen our commercial efforts and advance our clinical pipeline. Turning first to commercial performance. On HETLIOZ, talent as we payer denial for sighted patients with Non-24 proceeds. However, we're progressing efforts with commercial payers, Medicare, and Medicaid, to support basins, and increase reimbursement approval rates. Since 2021, over 15 states have revised their Medicaid prior authorization criteria, eliminating the restriction of HETLIOZ coverage on the base of others for the treatment of Non-24. At the same time, we see increase in the adoption of coverage for patients with night-time sleep disturbances in Smith-Magenis syndrome or SMS. We will continue to move these efforts forward and our committee to working with all parties to improve coverage for our patients. On SMS for the indication of night-time sleep disturbances, we're seeing continued interest by patients and caregivers attributed to direct-to-consumer campaigns. As we increase awareness around this SMS and our ongoing work with advocacy organizations such as prisons. Other educational initiatives for SMS are underway. As previously noted, many basis with SMS remain undiagnosed and are currently treated for various new developmental disorders. Our genetics work has identified that among patients with Autism, there is an increase in prevalence of the RAI1 deemed leasers and loss of function mutations. This is thus that some patients diagnosed with Autism may also have Thomas. We're evaluating opportunities to engage with the Autism community in elevate awareness of SMS among this population as well. On patent exclusivity for HETLIOZ, the products is currently a covered by a number of patterns listed in the FDA has orange book with explanations…

Thank you, Mihael. I'll begin by summarizing our first quarter 2022 financial results. Total revenues for the first quarter of 2022 were $60.2 million, a 4% decrease compared to $62.7 million for the first quarter of 2021. HETLIOZ net product sales for $37 million for the first quarter of 2022 compared to $39.3 million in the first quarter of 2021. Consistent with prior years and expectations, the first quarter of 2022 HETLIOZ revenue was impacted by the annual Medicare manufacturer contribution and the annual payer disruption linked to new plan years, plan changes, and reauthorizations, which we've seen in prior years. Additionally, the first quarter of 2022 reflects the continued insignificant increase of reimbursement challenges from payers to fill HETLIOZ prescriptions for patients with Non-24. Turning to finance, Fanapt, net product sales in the first quarter of 2022 were $23.2 million essentially flat as compared to $23.3 million in the first quarter of 2021. Fanapt, net product sales in the first quarter of 2022 decreased by 3% as compared to $24 million in the fourth quarter of 2021. Fanapt prescriptions in the first quarter of 2022 as reported by IQVIAX ponent decreased by approximately 2% compared to the fourth quarter of 2021. This decrease is consistent with the performance of Fanapt. We've seen in the first quarter of prior years. For the first quarter of 2022, Vanda recorded a net loss of $6.4 million compared to net income of $8.7 million for the first quarter of 2021. The net loss for the first quarter of 2022 included an income tax benefit of $1.1 million as compared to an income tax provision of $1.8 million for the same period in 2021. Operating expenses in the first quarter of 2022 was $67.9 million compared to $52.3 million in the first quarter of 2021. The $15.5 million increase was primarily driven by higher expenses, associated with the support of the HETLIOZ franchise, legal support related to ongoing litigation, awareness, DTC campaigns, and other corporate expenses, as well as higher R&D expenses related to the late-stage Fanapt development program. Operating expenses in the first quarter of 2022 were $8.5 million higher as compared to $59.4 million in the fourth quarter of 2021. This increase was primarily attributable to higher expenses associated with support of the HETLIOZ franchise, legal support related to ongoing litigation, and other corporate expenses. Vanda's cash, cash equivalents, and marketable securities referred to as cash as of March 31, 2022 were $435.2 million representing an increase of $57 million compared to March 31, 2021, and an increase of $2.4 million compared to December 31, 2021. Vanda expects to achieve the following financial decades in 2022, net product sales from both HETLIOZ and Fanapt of between $240 million and $280 million, HETLIOZ net product sales of between 1$50 million and $180 million, Fanapt's net product sales of between $90 million and $100 million, year-end 2022, cash of greater than $440 million. With that, I will now turn the call back to Mihales.
