Thank you, David. This is an exciting time for Rhythm, as our efforts around Bardet-Biedl syndrome are coming together on many fronts, putting us in a position to bring to patients, the first ever therapy to address the unmet needs of hyperphagia and severe obesity that affect the lives of patients and families living with this disease. Bardet-Biedl Syndrome or BBS, is a clinical syndrome with many features, including severe obesity from an early age, and an insatiable hunger or hyperphagia, which impact the health and quality of life for parents -- for patients, their families and caregivers. There is currently no effective treatment and we know from interviews and our work on health-related quality of life in patients and families, with BBS that was presented this week for the first time, just how dire the need is to control hunger and to stop thinking about food all the time. This quarter, as David said, we are one step closer, to delivering a transformative new treatment option to patients having completed our regulatory submissions in the US and EU. Setmelanotide has demonstrated clinical efficacy and safety, as well as, meaningful improvements for patients and their families, caregivers and health care providers. And we look forward, to reviewing some of these data today. Slide 13. The severe impact that BBS has on the lives of patients and families, is significant and we've made tremendous strides this quarter in documenting, qualifying and quantifying this impact. But the patients, caregivers and families clearly speak, best for themselves. As their quotes on this slide, from in-depth qualitative interviews that we conducted, with patients with BBS and/or their caregivers point to the stress and guilt of denying food to children with hyperphagia and point to how the world revolve around food which limits their focus on anything else. Pause here for an opportunity for you to read through some of these quotes. During our company all hands meeting, we heard last month from the mother of a child with Bardet-Biedl syndrome and her story reinforced our understanding of the impact BBS has on families and underscore the unmet need that exists in this community. She told us about the significant weight gain evident by two years old that continued as off the chart rate of weight growth and the challenges she faced in school with weight gain including physical, as well as social difficulties. She told us it was very tough. These first-hand accounts reinforced our understanding of the impact BBS has on families and underscore the unmet need that exists in these cases. Slide 14. This quarter we completed regulatory submissions for Bardet-Biedl syndrome and Alstrom syndrome in both the United States, as well as the European Union. In September, we submitted a supplemental new drug application to the FDA for IMCIVREE the branded name of setmelanotide for the treatment of obesity and control of hunger in adult and pediatric patients six years of age and older with BBS or Alstrom syndrome. We requested priority review from the FDA as part of the application. Based on FDA timelines we will know in November if our supplemental NDA has been accepted with priority review. And if granted that would mean a target FDA review period of six months from that date of acceptance. In October, we submitted a Type II variation application to the European Medicines Agency for IMCIVREE for the treatment of obesity and control of hunger in adult and pediatric patients six years of age and older with BBS or Alstrom syndrome. The review timeline in Europe is calendar based and we would expect a decision from the European Commission in the second half of 2022. We are confident in these submissions as they are based on data from the Pivotal Phase III trial in which setmelanotide achieved clinically meaningful and statistically significant reductions in body weight and in the unrelenting hunger associated with these syndromes. And these submissions include a series of comprehensive narratives for each individual patients supporting our belief that IMCIVREE has the potential to offer the first therapeutic option for the early onset, severe obesity and unrelenting hunger that characterize these syndromes. On Slide 15, here's a reminder of the trial design of our Phase III trial evaluating setmelanotide therapy in patients with Bardet-Biedl syndrome and Alstrom syndrome. This trial began with a 1:1 randomization in a double-blind placebo-controlled period of 14 weeks as highlighted in the light blue area and then progressed through a minimum of 52 weeks on setmelanotide therapy. All patients were titrated on setmelanotide at the beginning of the open-label portion and proceeded to complete at least 52 weeks on therapy for those who began on placebo and a total of 66 weeks on therapy for those who began on setmelanotide. Patients were evaluated for the primary and key secondary endpoints at 52 weeks on therapym, as shown here in the red boxes. Slide 16. The data from the 14-week double-blind placebo-controlled period are shown. Significant BMI reductions in patients with BBS on setmelanotide therapy versus placebo. Patients in the placebo group had negligible weight loss or BMI reduction at 14 weeks, compared to patients in the treatment group who reduced their BMI by an average of 4.3%. This translates to a statistically significant placebo-corrected setmelanotide treatment effect of 3.8% BMI reduction in 14 weeks. On Slide 17, as we said previously, this trial achieved all primary and key secondary endpoints with statistically significant and clinically meaningful reductions in body weight and hunger at 52 weeks. These data on patients with BBS from the Phase III trial are presented this week at the ObesityWeek Conference in the symposium by Dr. Robert Haws from the Marshfield Clinic the leading Bardet-Biedl syndrome key opinion leader in the United States. As you can see, we saw clinically significant reductions in body mass index across all 31 patients with BBS in this trial with a mean reduction of greater than 9% in both adults as well as children adolescents at 52 weeks of therapy on setmelanotide. Slide 18, setmelanotide achieved clinically meaningful reductions in hyperphagia that insatiable hunger that dramatically affects the lives of patients with Bardet-Biedl syndrome and their families. As we saw these data in both the initial 14-week double-blind period set here in the light blue blocks and out to 52 weeks. At 14 weeks, these data showed that patients in the placebo group had a modest reduction in hunger scores compared to the nearly 35% reduction achieved by the treatment group. Interestingly, when we compare the data trends over 52 weeks, there is a clear separation of hunger during the double-blind placebo-controlled period, highlighted in light blue box, followed by the placebo group reaching treatment levels rapidly after crossover to the open-label setmelanotide treatment period with the white background. Also, after the placebo-controlled double-blind period at week 14, you can see a brief rebound of hunger when patients on setmelanotide were retitrated onto the drug. This speaks to the sensitivity of hunger in Bardet-Biedl syndrome patients as well as the sensitivity of the setmelanotide response. Slide 19. At the ObesityWeek Conference this week, we are also presenting the first ever health-related quality of life results to measure the impact of setmelanotide therapy or patients with BBS. This is particularly important in this ultra-rare disease, as our research underscores the need to address the health-related quality of life burden experienced by patients. The data show after one year of treatment with setmelanotide, 85% of patients reported clinically meaningful improvements in or preserved their nonimpaired health-related quality of life status. For adult patients, changes to their impact of quality of life or -- Impact of Weight on Quality of Life score from baseline to 52 weeks was clinically meaningful with a mean increase of 12 points. For pediatric patients, we saw a clinically meaningful increase of the Peds Quality of Life score from baseline to 52 weeks of 11.2 points. Clinically meaningful improvements and clinical outcomes such as body mass index and hunger also mirrored improvements in health-related quality of life. Importantly, at the patient level, improvements were sustained over the 52-week prior period. With slide 21, I'd like to shift gears from BBS to our robust clinical development programs to treat more patients with obesity and hyperphagia due to genetically impaired melanocortin-4 receptor pathways. I want to begin by touching on a recent publication that illustrates the severity of disease for patients with heterozygous variants in several of our patients [ph]. Setmelanotide's growing body of eminence in these indications and then I'll summarize with a short update on our next wave of clinical trials. On slide 22, there is an article titled Implication of Heterozygous Variants in the Genes of the Leptin Melanocortin Pathway in Severe Obesity by Dr. Sophie Courbage and the team in the lab of Dr. Karine Clément of Sorbonne University in Paris it was published online this summer in the Journal of Clinical Endocrinology and Metabolism. This article details for the first time the phenotype of patients with early onset severe obesity and hyperphagia to the heterozygous variant in the melanocortin-4 receptor pathways, including leptin receptor POMC and PCSK1 genes comparatively to patients with homozygous or biallelic variant. Importantly, the comparison shows similarly severe obesity with similar early offset and severe hyperphagia, all of which underscore the genetics and the effective of the impaired pathway, a burden of the rare genetic disease or obesity and the need for growth. This research underscored the effects of a genetically impaired MC4R Pathway and the burden of rare genetic diseases of obesity and the need for therapy. On Slide 23, in addition to doctors Courbage and Clement, we are grateful for the support of the world's leading key opinion leaders in genetic obesities. Between The European Society for Paediatric Endocrinology The Obesity Medical Association and The Obesity Society Congress this week, 22 presentations of setmelanotide and uncovering rare obesity data have been presented by physicians, including Dr. Martin Wabitsch of the University of Ulm, Dr. Peter Kühnen of Humboldt University in Berlin; Dr. Jesús Argente of the Autonoma University in Madrid, Dr. Sadaf Farooqi from the University of Cambridge, Dr. Elizabeth Forsythe from the University College of London; and Dr. Robert Haws from Marshfield Clinics, who I mentioned previously. We've covered nearly everything today, except these efficacy results from complete top line analysis of our Phase II basket study, which were presented at ESPE in September. These data show weight loss and hunger reduction at three months on therapy in patients with SRC1 or SH2B1 gene deficiencies as well as a clear separation between patients who responded to setmelanotide treatment at three months and those who did not. All these presentations are available on our website. Lastly on Slide 24, our clinical development programs are on track, most notably the DAYBREAK and EMANATE studies, which aim to address severe obesity and hyperphagia across 36 genes with strong or very strong relevance to the melanocortin-4 receptor pathways. Site initiations are underway with investigator meetings planned for this month and next month and first patients in anticipated in the fourth quarter. There's a tremendous amount of activity ongoing and a lot of excitement. And with that I'll turn the call over to Jennifer. Thank you.
