Thank you, Dave. So thank you all for joining today. We realized we are probably not the lead story today, November 5th, Election Day, but we are really pleased with both the quarter and the progress we have made in 2024. We recognized at the start of 2024, this would be a year of execution with a highly anticipated readouts coming in 2025. We have executed and in addition to the expected readouts we have one unexpected readout which was presented today at the TOS meeting, an early look at the real-world data and French hypothalamic obesity patients. I will say a little more about that shortly. As shown on Slide 5, we remain focused on our three main value drivers. First, the team continues to drive results through strong execution of our global commercial strategy. Second, we are positioned to expand this patient opportunity to include hypothalamic obesity and we have increased confidence in the potential for this indication based on the new real-world data, efficacy data from the early-access program in France. We remain on track to report topline data from our Phase III trial and acquired hypothalamic obesity in the first half of 2025. Third, we continue to make progress with our MC4R agonist pipeline with DAYBREAK data presented at the Obesity Society's ObesityWeek, demonstrating potential new expansion opportunities and genetic indications, and we continue to progress our next generation MC4R agonist, the weekly RM-718 and the oral daily small molecule bivamelagon. Steady growth continues within IMCIVREE revenues for the third quarter coming in at $33.3 million, driven primarily by BBS sales globally. We continue to identify patients, physicians continue to prescribe IMCIVREE and payers are supporting access. We have an experienced rare disease team executing in challenging environments. And I know, we are only two years post-approval in the U.S. and continuing to introduce new markets internationally. It is early in the commercial lifespan of this opportunity. Our clinical programs are progressing as we remain on track to report topline data from the Phase III HO trial in the first half of 2025. The dropout rate remains less than 10%. We are targeting full enrollment of the Japanese cohort of patients by year-end. Our small molecule program has 50% of the targeted number of patients dosed or in screening. For the RM-718 study, we are completing the rat and non-human primate toxicology studies and we will submit those along with an amendment to allow dosing patients with hypothalamic obesity for more than four weeks to the FDA. We are targeting dosing the first hypothalamic obesity patients with 718 in the first quarter of 2025. We are doing this call, as Dave said, from ObesityWeek, and I want to highlight two of our poster presentations. First are the full results from the DAYBREAK trial. This was an ambitious undertaking where we sought to enroll patients with genetic variants in any one of 30 genes, which literature suggested maybe linked to the MC4R pathway. On Slide 6, you can see the design of the two-part trial and the open-label part-one, we reported out last December, patients who lost 5% or more after 16 weeks were eligible to enter the double-blind, randomized withdrawal part-two, where patients were randomized two to one to either continued setmelanotide therapy or placebo for 24 weeks. On Slide 7, you can see the patient demographics. 49 responder patients entered part-two and 39 patients completed this part of the trial. We had equal numbers of adults and pediatric patients. On average, they live with severe obesity based on their BMI or BMI-Z measurements. Slide 8 shows the summary results with a mean decrease in BMI of 12.4% in the 32 patients on continuous setmelanotide therapy for a total of 40 weeks. And 84% of patients on setmelanotide maintained or further decreased their BMI beyond the initial 5% as opposed to only 29% of patients randomized to placebo during the 24-week stage two of the trial. Overall, we are quite pleased with the results. The trial design worked. The open-label trial period identified patients who seemed to be true responders in that those randomized to continue treatment continue to respond, whereas those randomized to placebo mostly regressed towards baseline. On Slide 9 you can see the individual spaghetti plots for the four of these genes or gene groups. The blue lines represent setmelanotide, whereas the green lines represent the placebo patients. Also note that scales on the graph for each gene are different and were adjusted to accommodate those patients with the greatest decrease in their BMI for that gene group. I won't go through each of the panels, but if you look at the PHIP gene in the upper left, you can see the adult patients on the left and the pediatric patients on the right. In general, those continuing on-setmelanotide had a good response, whereas the three patients randomized to placebo regained weight. The PHIP gene was the gene with the highest overall percentage of responders, particularly in those who completed part-one. The key learnings from this trial is that there are patients who seem to have a clear response to setmelanotide suggesting their variant is impairing signaling through the MC4R pathway. The challenge for future development will be identifying those patients with true loss-of-function variants, recognizing for many of these genes, relatively little work has been done on the different variants, leaving most variants classified today as VUS or variants of unknown significance. Our expectation is that we will do additional research on one or more of these genes, but that work will be done with one or both of our second generation programs. Now, I want to finish my introductory comments talking about HO. We know there is a significant unmet medical need with no approved therapies and we believe the prevalence is in the range of 5,000 to 10,000 patients in each of the U.S. and Europe, as we've described previously, and we believe there maybe similar numbers of patients in Japan. Importantly, unlike BBS, most of these patients are diagnosed and under the care of endocrinologists. We reported out Phase II data in mid-2022 and moved directly to the randomized placebo-controlled 60-week Phase III trial. Both France and Italy in recognition of this significant unmet medical need, the absence of approved therapies and the strength of the Phase II data and an unusual move have made setmelanotide available through paid early-access programs. Patients from France began enrolling late last year and Italian patients are just beginning to receive treatment under the program. Real-world data from the initial French patients which was presented today at TOS is shown on Slide 10. Eight adult patients with a mean age of 31 who had undergone brain surgery 12 years earlier at the mean age of 19 have been followed for three to six months on setmelanotide. As you can see from the slide, they were severely affected with a mean BMI of 44. On average, these eight adult patients had a mean BMI decrease of 5.6% and 12.8% at one in three months respectively after initiating treatment. Patients have continued to lose weight with five patients who have reached the six-month time point experiencing a 21.3% on average decrease in their BMI. We see this data as important for multiple reasons. It is the first new data we have presented since the original Phase II readout in 2022. We had relatively few adult patients in the Phase II trial and almost no adults in the long-term extension leaving us with an important unanswered question, would adults be less responsive than children who are being treated in closer proximity to the onset of their HO. This data set goes a long way in answering that question. These patients were adults with a mean age of 31 as I said, who are on average 12 years out from the time of their injury. The response to date has been consistent and that's one of the most remarkable things is the consistency of the response and robust, further strengthening our conviction in the importance of the MC4R pathway in this disorder and the potential role setmelanotide may play in the management of hypothalamic obesity. So finally on Slide 11 is a summary of our upcoming milestones. The PDUFA date for our U.S. IMCIVREE label expansion to include patients ages two to up to six years old is December 26th, and Jennifer will touch on that. Based on the progress of initial enrollment and sites opening, we expect to complete enrollment in the 12-patient Japanese cohort of our Phase III acquired hypothalamic obesity trial by the end of this year. We also expect to complete enrollment in two of the EMANATE substudies, POMC, PCSK1 and SH2B1 by the end of the year. We do not anticipate being able to achieve a full enrollment in the other two substudies LEPR and SRC1. In the first quarter of 2025, we anticipate we will complete enrollment in the 28-patient Phase II trial evaluating bivamelagon and also in the first quarter begin dosing patients with acquired hypothalamic obesity and Part C of our Phase I trial with a weekly MC4R agonist RM-718. And as we have said many times, our topline data readout from the pivotal 120 patient cohort in our global Phase III trial of setmelanotide with acquired hypothalamic obesity is on track for the first half of the year. With that, I'll turn the call over to Jennifer.
