Thank you, Mike, and good morning, everyone. I'll start with sotagliflozin, our novel oral SGLT1 and SGLT2 inhibitor, which is in late-stage development in both HCM and type 1 diabetes. I want to take a moment and remind everyone of the important and unique effects of sotagliflozin's mechanism of action. Sotagliflozin is the only dual inhibitor of both SGLT1 and SGLT2, and I want to emphasize the importance of the SGLT1 effects. While SGLT2 is expressed primarily in the kidney, SGLT1 is expressed in the kidney, but also in other tissues, particularly the GI tract and the heart as well as the endothelial. Inhibition of SGLT1 in the GI tract is important in postprandial glycemic control in people with T1D. And we believe the inhibition of SGLT1 in the heart has important effects on myocardial health, particularly in disease states like HCM. It is also noteworthy that SGLT1 expression is upregulated in patients with ischemic heart conditions and in patients with hypertrophic cardiomyopathy. Lexicon continues to study and publish the biology of inhibition of the dual effects of both SGLT1 and SGLT2. As Mike mentioned, we are rapidly approaching 2 important potential catalysts for sotagliflozin, both of which are anticipated around midyear. First, for HCM, we expect enrollment of our global Phase III SONATA trial of sotagliflozin in HCM to be completed by mid-2026. This pivotal study is evaluating approximately 500 patients with HCM, randomized across 130 enrolling sites in 20 countries and includes patients with obstructive and non-obstructive phenotype. Based on current enrollment trends, we continue to anticipate top line data from this study in the first quarter of 2027. In type 1 diabetes, we remain on track for an NDA submission of Zynquista for glycemic control in adults with type 1 diabetes based on clinical data from the STENO1 investigator-initiated trial. Based on the data from the study thus far and FDA discussions, we believe there is potential for Zynquista to be approved in 2026. On the base of our activities with SONATA-HCM trial and with the STENO study group, we believe that sotagliflozin has the potential to meaningfully advance the treatment landscape for people with HCM and for those with T1D. With this in mind, let me tell you a bit more about what gives us confidence in sotagliflozin in these 2 indications. As a reminder, SONATA-HCM is a large global registration trial with a primary endpoint of placebo-adjusted improvement in the KCCQ CSS score and is designed to support a regulatory filing and broad label in HCM. The study randomized adults with symptomatic HCM, which includes both obstructive and nonobstructive phenotypes. With its unique dual mechanism of action, we believe sotagliflozin should provide clinically meaningful improvements in both symptoms and function in both the obstructive and nonobstructive disease. Sotagliflozin is acting through a dual mechanism or a distinct mechanism from CMIs. Patients on a stable dose of CMI who continue to have heart failure symptoms are also enrolling in the study. What makes sotagliflozin different is that it's acting both as a hemodynamic agent and as a metabolic agent to treat HCM. To explain further, through SGLT1 inhibition, sotagliflozin acts as a metabolic agent directly on the heart to improve the heart -- the functioning of the heart muscle. Additionally, sotagliflozin is acting as a hemodynamic agent by acting on the cardiorenal axis to improve the body's fluid balance and improve outcomes. In total, if you consider its once-daily dosing regimen, established safety profile in clinical studies and post-marketing use and proven CV outcomes in patients with heart failure, we believe that sotagliflozin has the potential to be broadly adopted in the management of HCM with a strong benefit risk profile. In recent months, we've continued to present additional evidence supporting sotagliflozin's unique potential. In addition to recent data presented on T1D, I'd like to focus on the SOTA-P-CARDIA study of sotagliflozin at the American College of Cardiology Annual Meeting. These analyses provided further evidence of benefit across patient subgroups potentially related to its mechanism of action. As previously reported, results from SOTA-P-CARDIA demonstrated a placebo-adjusted 19-point improvement in the KCCQ score. These new analyses showed meaningful effects of SOTA on changes in patient functioning as measured by the 6-minute walk test. Additionally, there was an impact on a number of metabolic parameters, including a reduction of epicardial fat in patients treated with sotagliflozin. While not shown in this slide, there was also a reduction in the left atrial volume in those patients treated with sotagliflozin. Collectively, the data from this study demonstrate meaningful benefits on symptoms, function and physiology, which may validate the effectiveness of SOTA in HCM for clinicians. Turning now to Zynquista in type 1 diabetes. As we have previously discussed, the FDA has confirmed that data from STENO1, third-party funded investigator-initiated study being conducted by the STENO Diabetes Center in Denmark is adequate to support a resubmission for our NDA provided patient exposure and safety data requirements are achieved. Based on the data that we have seen to date, we are optimistic that we are on track for NDA resubmission midyear with potential approval in 2026. There are 3 key points supporting our time lines and potential for Zynquista. First, enrollment is going as expected in the trial. Second, we remain comfortable with the data and safety profile STENO1 has generated to date. And third, we are continuing to work on an ongoing basis with the FDA on the final parameters surrounding the exact formatting and submission dates for the data. In short, there are a number of items that need to be completed in order to file midyear, but we remain on track. If approved, Zynquista will be the first and only oral adjuvant to insulin therapy ever approved for glycemic control in type 1 diabetes. Our final cardiometabolic program is LX9851, our first-in-class non-incretin oral small molecule inhibitor of ACSL5 in development for obesity and associated metabolic disorders. Global development by our licensee, Novo Nordisk continues to advance and LX9851 is now in the clinic following Novo's initiation of a Phase I study in March. We are pleased by Novo's continued enthusiasm for this candidate and its novel mechanism and how swiftly Novo has advanced this program into clinical development. Now turning to our chronic pain program. Like sotagliflozin, pilavapadin has a broad pipeline and a pill potential. Pila is a novel investigative therapy targeting AAK1. Beyond DPNP, we believe that there are a number of potential applications for pilavapadin. The AAK1 pathway is central to a number of cellular processes such as synaptic signaling between neurons involved in pain signaling and also spasticity. With this in mind, we are conducting IND-enabling work in multiple additional neuroscience indications. Last month, we presented 2 additional data sets at the AAN Annual Meeting that further validate the development of pilavapadin in DPNP as well as other neuroscience indications. First, we shared additional efficacy data from the PROGRESS-3 Phase IIb study supporting the selection of pilavapadin 10 milligrams for Phase III development in DPNP. Following the top line results from the PROGRESS Phase II study last year, we knew we needed to deepen our understanding of these results through additional analyses. The data presented at AAN provided additional validation needed to advance pilavapadin 10 milligrams as well as a deeper understanding of the profile of this novel mechanism. The data we have seen to date give us further confidence that pilavapadin is Phase III ready in DPNP. Second, we presented preclinical evidence supporting pilavapadin as a novel oral therapy for spasticity, including evaluation in preclinical models of multiple sclerosis and spinal cord injury. The data shared at AAN underscore the opportunity to expand the potential of pilavapadin beyond DPNP, consistent with the pipeline in a pill opportunity that we have discussed. I'll now turn it over to Scott to provide an update on the company's financials.
