Thanks, Matt. Good afternoon, everyone, and thank you for joining our call. With me today are Ryan Maynard, our Chief Financial Officer; Dr. Joana Goncalves, our Chief Medical Officer; and Scott Terrillion, our General Counsel and Head of Government Affairs. Our strategy at Cara Therapeutics is to change the treatment of chronic pruritus with our innovative and differentiated asset difelikefalin. Our highest priority is to execute on our three unique late-stage programs in dermatology and nephrology, which drive the greatest potential long-term value for our company. And we are excited to have multiple fully funded value inflection milestones within these programs over the next 12 months. Today, I will provide an update on the funding of our wholly owned oral difelikefalin pipeline. Next, I will discuss the progress in our three late-stage programs including expectations for Part A of our KIND 1 atopic dermatitis study, which is scheduled to read out in December of this year. Finally, I will address the performance of KORSUVA injection in the US and discuss the recently released 2024 ESRD rule. After that, Ryan will provide a financial update and we will subsequently open up the call to Q&A. With that, let me start with our recent announcement regarding the monetization of our ex-US royalties for KORSUVA injection and Kapruvia. On November 1st, we entered into a royalty interest purchase and sale agreement with Healthcare Royalty. Under the terms of the agreement, Cara received an initial payment of $17.5 million less certain expenses. We will receive an additional payment of $20 million upon Kapruvia receiving a certain minimum price in Germany, which is expected to occur this quarter. In addition, Cara will receive a $2.5 million milestone payment based upon achieving certain 2024 performance levels of KORSUVA in Japan. In exchange, Healthcare Royalty will receive all royalties due to Cara from KORSUVA injection and Kapruvia ex-US license agreements with CSL Vifor and Maruishi. The aggregate royalty payments to Healthcare Royalty are capped at two times the payment to Cara if received before the end of 2029. Otherwise, the payments are capped at 2.8 times after which Cara will resume receiving all royalties from both CSL Vifor and Maruishi. The arrangement with Healthcare Royalty specifically excludes KORSUVA injection in the US and all of Cara's oral difelikefalin internal development programs. Non-dilutive financing is an important part of our strategy to drive the continued development of our very promising pipeline, which has always been key to building sustainable long-term value for Cara. Closing this non-dilutive transaction extends our cash runway into 2025. This helps us reach critical catalysts and milestones that we believe will display the potential of our difelikefalin catheter pipeline and start to display the underappreciated value in Cara. Next, let me discuss the progress of our multiple late-stage pipeline programs. First, our Phase 3 KIND 1 trial in pruritus associated with atopic dermatitis is approaching a key near-term milestone. We now plan to release top-line efficacy and safety data for Part A, the dose-finding portion of this trial, in mid-December in order to increase the visibility into this trial. Recall, chronic pruritus is the most common and most burdensome symptom of atopic dermatitis affecting almost 100% of the approximately 12 million adult patients in the US. In recent years, there has been significant investments and innovation in the treatment of moderate to severe AD, resulting in the development and approval of new biologics and JAK inhibitors. Despite these developments, a large segment of the AD market remains underserved. We are targeting roughly one-quarter of the total AD market. These are mild to moderate AD patients with moderate to severe itch, also referred to as itch-dominant AD. Numerically, that's about 3 million addressable itch-dominant patients in the US, who are primarily managed with topical corticosteroids. While TCS may treat skin lesions, they often fail to effectively address the burdensome chronic itch that severely impacts these patients' quality of life. So there is a significant void in the treatment continuum and a need for an oral therapy with a favorable safety and tolerability profile to effectively treat the debilitating itch in these patients. Our KIND program is tailored to specifically address this unmet need for a targeted oral anti-pruritic treatment for mild to moderate AD patients who are very itchy. No company to date has focused on this market segment and enriched its trials with this patient phenotype. Today, we can confirm that 80% of the patients enrolled in Part A of KIND 1 have a baseline body surface area of less than 10% and a mean itch score of greater than seven, meaning most patients in the trial have mild to moderate skin lesions with severe itch. As you will recall, this is also the subgroup of patients that showed the best clinical benefit with oral difelikefalin in our KARE Phase 2 monotherapy trial. In contrast to our Phase 2 trial, our Phase 3 KIND program is designed to mimic likely future real-world utilization in patients. Difelikefalin is used on top of mid-potent TCS and compared to TCS alone, an active comparator. With this higher clinical hurdle and four treatment arms, Part A of KIND 1 is not powered for statistical significance. We have enrolled 287 patients with the intent to select the most favorable dosage strength and determine the sample size for the confirmatory part of the Phase 3 program. The KIND 1 Part A readout is a significant catalyst and mirrors the future of this program. We believe that Part A will be a good proxy for the likely outcomes of the confirmatory KIND 1 Part B and KIND 2 studies. The patient enrollment criteria, study conduct, and end points in the confirmatory studies are expected to be the same as for KIND 1 Part A. In addition, the study sites from Part A will participate in Part B along with some new added sites. We are excited to share the results of KIND 1 Part A with you in the near future. Now turning to our other two late-stage programs that also target sizable patient populations with a lack of treatment options. Enrollment in our Phase 3 KICK 1 and 2 trials in pruritus associated with advanced chronic kidney disease is progressing well, and we continue to expect top-line results in the second half of 2024. The approval of KORSUVA injection validated this mechanism, laying the foundation for our nephrology franchise. We see a natural extension of difelikefalin into earlier stage patients with the oral formulation. There are roughly 300,000 pre-dialysis advanced stage CKD patients who suffer from moderate to severe pruritus in the US alone. Importantly, these patients do not fall under the capitated reimbursement system that covers dialysis patients. Hence, we see a significant commercial opportunity in this underserved patient population. Our Phase 2/3 KOURAGE 1 trial in notalgia paresthetica is tracking to its first data readout of Part A in the second half of 2024. With no approved therapies and an addressable population of at least 650,000 patients in the US who are under the care of a provider, most often a dermatologist, we believe oral difelikefalin has the potential to unlock a sizable, new market in dermatology. Now let me turn to the performance of KORSUVA injection in the US. For the third quarter of 2023, net sales for KORSUVA were $4.4 million, translating into $1.9 million of profit recorded as revenue to Cara. Wholesaler shipments to dialysis clinics totaled 91,000 vials, a 36% increase from the prior quarter. 68% of these vials were shipped to Fresenius clinics, and the remainder split between DaVita and the other dialysis organizations. At Fresenius, orders grew by more than 37% quarter-to-quarter, reaching 62,000 vials. By the end of the third quarter, over 1,000 Fresenius clinics, or 37%, have placed reorders. That's up from 27% at the end of the second quarter. Additionally, 1,478 clinics, or 55%, had dosed at least one patient at the end of the third quarter. Importantly, following the ESRD prospective payment system rule, Fresenius decided to reallocate remaining inventory that was shipped in the third quarter of 2022 within its network of clinics. As a result, we expect shipments from CSL Vifor to wholesalers to be small in the fourth quarter of this year and the first quarter of 2024, translating into minimal revenues accrued to Cara in these quarters. At DaVita, we continue to observe steady growth in demand. Orders grew by 20% quarter-to-quarter to 13,000 vials. Over 500 clinics or 19% had ordered KORSUVA at the end of the third quarter. That's up from 15% at the end of the second quarter. Reorder rates remain strong with 76% of clinics placing repeat orders. As a reminder, since there is minimal inventory held at DaVita clinics, we believe the growth in clinic orders represents a good proxy for the growth in patient demand. At mid-size and independent dialysis organizations, KORSUVA utilization continued its momentum. Orders grew by 47% quarter-to-quarter to over 16,000 vials. At the end of the third quarter, 18% of clinics in this market segment had placed orders. That's up from 17% at the end of the second quarter. In addition, 77% of these clinics placed repeat orders, up from 68% at the end of the second quarter. US renal care remains the largest buyer of KORSUVA in the MDO/IDO segments. Approximately 80% of USRC clinics had ordered KORSUVA by the end of the third quarter, and 83% of these clinics had placed repeat orders. Overall, our expectations for KORSUVA injection are now greatly reduced, but we remain confident in the mechanism of action and benefit of KORSUVA. The provider and patient feedback for KORSUVA remains highly positive, and its good clinical performance has continued to fuel growth in vial demand. But its use will not likely reflect the existing clinical need. The significant challenges in the uptake of KORSUVA, even with its TDAPA designation, stem from the unique capitated dialysis reimbursement system in the US, which really does not foster innovation. On October 27, CMS published the end-stage renal disease Prospective Payment System final rule for the calendar year 2024. We are disappointed that CMS rejected our request to extend the TDAPA period for KORSUVA. Furthermore, CMS maintained the proposed methodology for calculating the add-on adjustment, which in our view is flawed and results in a significant shortfall in funding for KORSUVA and other innovative drugs with TDAPA designation in the future. As a result, we now believe that KORSUVA's commercial potential will be meaningfully lower than we previously expected. However, Cara fundamentally is a development company, and our greatest source of value is our wholly-owned oral difelikefalin pipeline. We remain laser-focused on maintaining a strong balance sheet and driving progress in our three late-stage programs to deliver value catalysts ahead. I would now like to turn it over to Ryan for additional details on our third quarter financial results. Over to you, Ryan.
