Thank you, Louis, and thanks, everyone, for joining our conference call today. Q3 2023 was the strongest revenue quarter in Harmony's history. The pace of growth in net revenue and average number of patients on WAKIX is rarely seen in year four of commercialization of an orphan rare disease product. What is driving this strong continued growth of WAKIX and narcolepsy is the meaningfully differentiated product profile, the strong underlying patient demand, the sizable market of 80,000 patients diagnosed with narcolepsy in the US, and the consistent executional excellence of our commercial organization. I am proud of this accomplishment, and even more important, I am pleased that our efforts continue to help even more people living with narcolepsy. I also know that there are many more people living with narcolepsy who could potentially benefit from WCAGS, and that is what we are focused on. For the third quarter of 2023, we reported WCAGS net revenue of $160.3 million, an increase of 37% year over year. We believe that the vast market opportunity which remains in narcolepsy, along with the differentiated product profile of WAKIX, provides us the ability to grow the franchise for years to come, and we remain confident that WAKIX represents a $1 billion plus opportunity in adult narcolepsy alone, and we are well on our way. In addition to our very strong commercial performance in Q3, We also continue to advance our current pitocin life cycle management programs, as well as expand our pipeline and diversify our portfolio beyond sleep-wake. Kumar will provide additional details on our clinical development programs later in the call. Earlier this month, we reported top-line results from the Phase III in-tune study of pitocin in patients with idiopathic hypersomnia, or IH. While the primary endpoint did not reach statistical significance during the randomized withdrawal phase, a robust clinical effect was demonstrated in the open-label phase of the study, and almost 90% of the patients who completed the trial elected to continue into the long-term extension study, which is ongoing. I want to reiterate our commitment to the IH patient community as we are actively pursuing an indication for Pitocin and IH and are optimistic in our ability to bring a non-scheduled treatment option to patients living with IH and the healthcare professionals who treat them. We believe that, based on the totality of the evidence that we have seen thus far, along with the Tolleson receiving orphan drug designation for IH, there is an opportunity for us to work with the FDA on a path forward. Once we have completed our review of all the data, we will engage with the agency with this goal in mind. Our current life cycle management programs for Pitocin represent about 100,000 diagnosed patients in the U.S. So if successful, these could contribute up to an additional $1 billion of revenue to the WCAG franchise. Moving to the ongoing work with our partner BioPregé on new formulations of Pitocin with the goal to potentially extend the Pitocin franchise with new IP out beyond 2040. We are advancing these programs into the clinic, and Kumar will provide more detail on them later in the call. Another key component of our growth strategy is acquiring new assets through business development to expand our pipeline beyond WACICS and diversify our portfolio beyond SleepWake. I am excited to report that we recently closed the acquisition of Zynurba Pharmaceuticals and have added the investigational product Zygel to our pipeline. This acquisition represents an excellent strategic fit for Harmony, with development programs focused on orphan-rare neuropsychiatric disorders with significant unmet medical needs. With Zygel, we added a novel product candidate and two late-stage development programs that could potentially launch during the WAKIX lifecycle. Zygel is currently in a pivotal Phase III trial for patients with Fragile X syndrome, with another opportunity based on positive Phase II data in patients with 22q deletion syndrome. Both of these indications, if successful, represent a significant market opportunity with the potential to serve 80,000 U.S. patients living with Fragile X syndrome and another 80,000 with 22q deletion syndrome. We have welcomed former Zynurba members to the Harmony team and are excited to work with them to advance the Zygel development programs and bring a potential new treatment option to patients living with orphan-rare neuropsychiatric disorders with high unmet medical needs. As for business development, we are not stopping with the Zynurba acquisition, but remain very active with a dedicated business development team which is continually assessing the BD landscape. We remain focused on orphan-rare neurology assets, and our assets in other neurological diseases where we can leverage our existing expertise and infrastructure. We are looking for assets across a range of development stages, including both early and late stage, with the potential to launch both during and after the WAKETS lifecycle. And finally, given our continued confidence in the underlying strength of the business and our conviction in the growth potential for the company, This morning, we announced a new share repurchase program of $200 million. Given our financial flexibility, we are committed to deploying capital to maximize shareholder value. In conclusion, Q3 2023 was the strongest revenue quarter in Harmony's history, and our business is strong. We are committed to bringing a non-scheduled treatment option to patients with IH, and are advancing every aspect of our business, including our pipeline programs and business development efforts. I am very proud of the dedication and commitment across our organization as we remain focused on developing and commercializing innovative treatments for patients living with rare neurological diseases who have unmet medical needs. I will now turn the call over to Jeffrey Dirks, our Chief Commercial Officer, to provide more details on our strong third quarter commercial performance. Jeff?

Thanks, Jeff. Q3 was another strong quarter for WCAGS. We had the strongest revenue quarter in our history with continued growth and momentum in our underlying business fundamentals and top-line performance metrics. Net sales for the third quarter were $60.3 million, which represents a 37% growth from the same quarter prior year, and the first quarter of over $150 million in net sales. We continue to see strong double-digit growth in net sales for WCAG in year four of our commercialization, which reflects the high interest of WCAG in the narcolepsy market. The consistent growth in the business reinforces our long-term belief that WACIX represents a billion-dollar-plus opportunity in adult narcolepsy alone. I'd like to share a few key highlights from our performance in the third quarter on slide five. The average number of patients on WACIX in the third quarter increased to approximately 5,800, an increase of approximately 350 average patients sequentially from what we reported last quarter. This impressive growth in average patients in the third quarter was driven by strong top line demand and new patient starts that offset typical summer seasonality, yielding quarterly results consistent with the results we saw in Q2. The growth in average patients on WCAG speaks to continued product adoption, and most importantly, the large remaining diagnosed patient opportunity that we continue to tap into each quarter as the market allows. Strong patient interest and prescriber adoption continue to be key drivers of the growth in average number of patients on WACICS. We saw continued strengthening of the WACICS prescriber base in Q3, both in depth and breadth of prescribing. The number of unique prescribers on WACICS increased again in the third quarter. And importantly, we continue to see growth in the WACICS prescriber base expand beyond healthcare professionals enrolled in the Oxibate REMS program. In addition, we saw growth in the depth of prescribing within the OxyBait enrolled healthcare professionals, even with the availability of new and generic OxyBait options. As we continue to share the meaningfully differentiated product profile of WAKIX and the unique feature of being the only FDA-approved treatment for EDS and cataplexy that is not scheduled as a controlled substance, offers broad clinical utility and appeals to a broader narcolepsy healthcare professional audience and patient base, which is a driver of our continued growth. We continue to see meaningful penetration and growth across the approximately 9,000 narcolepsy-treating healthcare professional prescriber base. And recent market research conducted in October of this year supports our view of continued future growth in WACIX prescribing. Research conducted with approximately 70 healthcare professionals with and without experience with WACIX prescribing showed the following. 100% of the healthcare professionals surveyed with WACIX clinical experience showed stated they would prescribe the same or increase prescribing of WCAGS in the next six months. More than 40% of those healthcare professionals surveyed who had not prescribed WCAGS to date indicated the intent to prescribe WCAGS in the next six months. Nearly 60% of those healthcare professionals who had prescribed WCAGS to date stated they were likely to recommend WCAGS to peers and colleagues. And consistent with previous waves of research, one of the highest-performing drivers and differentiators for WCAGS with the unique feature as the only non-scheduled treatment option. The availability of new and generic OxyBait options hasn't impacted the continued growth or existing strong payer coverage for WCAGS, given the meaningfully differentiated product profile. Our ability to reach and educate the broad narcolepsy-treating healthcare professional universe has tapped into the full-diagnosed adult narcolepsy patient opportunity gives us confidence in continued growth and the long-term growth potential for WACICS. In summary, I'm excited by the strong commercial performance in the third quarter. In fact, the strongest revenue quarter for Harmony to date. We saw strong growth of 37% in net sales versus the same quarter prior year. We saw strong growth in the average number of patients on WACICS to approximately 5,800. an increase of approximately 350 sequentially from what we reported last quarter. We saw continued expansion and strengthening of the WACIX prescriber base within and beyond OxyBait REMS-enrolled healthcare professionals. And payer coverage remains strong, even with the availability of new and generic OxyBait options. I appreciate the dedication and impact of the entire commercial team and the passion that they have for our business and the NARC LSD patient community. This strong performance gives us confidence in the long-term growth potential for WCAG and reinforces our belief that WCAG represents a billion-dollar-plus opportunity in adult narcolepsy alone. I would like to now turn the presentation over to Kumar Badur, our Chief Medical Officer, to provide an update on our clinical development pipeline. Kumar?
