Thanks, Len. Today, I'll focus on the key updates from our development pipeline. For a comprehensive summary of our mid- and late-stage pipeline, please refer to the programs and Clinical Development section of our 10-Q. I'll start with our complement-mediated disease franchise, beginning with cemdisiran, our C5 siRNA. Regulatory submissions for cemdisiran monotherapy in generalized myasthenia gravis or gMG, have been accepted for review by both the FDA and the EMA. The FDA target action date is in November of this year, while the European Commission decision is anticipated in the second half of 2027. If approved, cemdisiran would represent a highly differentiated treatment option in gMG and be the first siRNA approved for this disease. We believe cemdisirin's efficacy, safety and convenient 4x per year subcutaneous dosing profile, highly differentiated from C5 antibodies and other modalities approved for gMG. For cemdisiran, in combination with pozelimab, our C5 antibody, we continue to expect registrational data in paroxysmal nocturnal hemoglobinuria or PNH, in the fourth quarter of this year. Our Phase III lead-in cohort that compared this combination with ravulizumab an FDA-approved antibody to C5 for the treatment of PNH suggested that our combination could provide a more convenient monthly subcutaneous regimen that could also improve disease control based on LDL measures and support our hypothesis that complete complement blockade in this disease is required for sustained disease control. As a reminder, the registrational study is evaluating non-inferiority of our C5 combination versus eculizumab, the other C5 antibody that is FDA approved for the treatment of PNH using co-primary endpoints of intravascular hemolysis control as well as transfusion avoidance. In ophthalmology, our C5 approach in geographic atrophy, or GA, remains on track to read out 26-week data from our exploratory cohort in the fourth quarter of 2026, which will help inform our pivotal strategy. As a reminder, we are evaluating systemic administration of cemdisiran with or without pozelimab with the goal of slowing the rate of GA lesion growth and associated declines in visual acuity while avoiding the ocular safety issues that have been observed with certain FDA-approved therapies. We are also evaluating intravitreal pozelimab in GA to provide optionality and are actively developing co-formulations of this with other agents such as aflibercept to address comorbid retinal disease settings. In immunology and inflammation, to follow on, on Dupixent's success, we continue to advance a series of next-generation fully human antibodies and bispecifics designed to build on Dupixent by extending duration, enhancing target coverage and potentially improving efficacy. We have enrolled initial healthy subjects in our first-in-human trial for a long-acting IL-13 antibody and expect to begin dosing patients with atopic dermatitis later this quarter with plans to execute an expedited path to starting registration-enabling studies potentially by the end of next year or early 2028. Our initial clinical data indicate that this antibody has a prolonged half-life that has the potential to extend the dosing interval well beyond those achieved with currently approved products in this category. First-in-human studies of our other next-generation long-acting antibodies are planned with next-generation Dupixent or Supi-Dupi expected to be clinic ready by early 2027 and additional candidates, including our IL-4/IL-13 bispecific next year. Briefly on to oncology. Ubamatamab, our MUC16xCD3 bispecific continues to demonstrate promising monotherapy activity in low-grade serous ovarian cancer, a subset of advanced ovarian cancers, and we plan to present detailed data in this setting at a medical meeting this fall. We also continue to advance pivotal studies for Lynozyfic, our BCMAxCD3 bispecific in multiple myeloma and pre-malignant conditions, including a newly initiated pivotal study in high-risk smoldering multiple myeloma. We expect results next year from the LINKER-MM3 study, our confirmatory trial of Lynozyfic monotherapy versus standard of care in patients who have received at least 1 but no more than 4 lines of therapy. In 2028, we expect minimal residual disease or MRD negativity results from our first-line study in transplant ineligible myeloma patients as well as our Lynozyfic carfilzomib combination study in myeloma patients who have received one or more prior lines of therapy. At the American Society of Clinical Oncology, or the ASCO meeting, we presented first results from the Phase I/II LINKER-AL2 trial of Lynozyfic monotherapy in patients with second-line plus systemic light chain or AL amyloidosis. Normalization of free light chain occurred by day 15 across all doses and 100% of patients achieved a hematologic complete response at the highest dose tested. The majority of patients with renal or cardiac involvement demonstrated improvement in organ function despite short follow-up. The Phase II portion of the study which has registrational intent is now ongoing. A Phase III study in first-line light chain amyloidosis is planned to start early next year. Moving to anticoagulation. We are on track to initiate the remaining Phase III studies from our comprehensive Factor XI program this year, featuring cenvacibart, our catalytic antibody formerly known as REGN7508 and amrecibart, our H2 antibody formerly known as REGN9933. Pivotal results from our studies in venous thromboembolism or VTE prevention following total knee replacement surgery are expected in the first half of 2027. Also in 2027, we anticipate results from the Phase II ROXI-ATLAS study, which evaluates both Factor XI antibodies against apixaban in stroke prevention in patients with atrial fibrillation or SPAF, which is expected to provide us with important insights into bleeding risks after 3 months of observation. We have also begun enrolling patients in our Phase III SPAF trial, ROXI-INCLINE, that will evaluate both of our antibodies against placebo in patients who are not candidates for conventional anticoagulant therapy. We remain excited about our program and favor antibodies as opposed to a small molecule approach as we believe antibodies enable greater and more specific inhibition of Factor XI, leading to improved antithrombotic activity without increased bleeding risk or other off-target safety issues. Turning to obesity. Olatorepatide, our dual GLP-GIP receptor agonist in-license from Hansoh continues to advance. Data from Hansoh's Phase III study of olatorepatide in Chinese patients with obesity, which top line in March, will be presented as a late breaker at the European Society for the Study of Diabetes Conference, or EASD in October. Acknowledging the inherent limitations of cross-trial comparisons, olatorepatide generated weight loss that was comparable to the weight loss observed in a similar study of tirzepatide in China, while demonstrating a favorable gastrointestinal tolerability profile, including meaningfully lower rates of diarrhea, nausea and vomiting. We remain on track to commence Phase III studies later this year in addition -- in patients with obesity as well as patients with obesity and type 2 diabetes. In addition to the olatorepatide monotherapy program, we also continue to advance our combination of ola and Praluent, our PCSK9 antibody to address patients with obesity or type 2 diabetes that have comorbid hypercholesterolemia. Also at EASD, we will present 52-week results from the COURAGE study, including accompanying MRI findings in a subset of patients. Adding trevogrumab to semaglutide did not drive additional weight loss but did show encouraging skeletal muscle mass preservation versus semaglutide alone. These findings reinforce our belief that preventing muscle mass loss may become increasingly important as obesity treatment evolves, particularly in older patients with sarcopenic obesity. In rare disease, we expect an FDA decision in August for garetosmab, our Activin A blocking antibody in fibrodysplasia ossificans progressiva or FOP. If approved, garetosmab would be the first treatment shown to reduce the number of new abnormal bone formation lesions as well as clinician-assessed flare-ups in FOP patients. From our earlier-stage pipeline, we are planning to present at medical meetings this fall, some promising clinical data from our pipeline of siRNAs for metabolic dysfunction-associated steatohepatitis or MASH, and for our NPR1 antagonist antibody, [indiscernible] for the treatment of postural orthostatic tachycardia syndrome or POTS. Finally, we continue to work with the U.S. government and international health organization to deliver potential new treatments for the devastating recent Ebola virus epidemic that is driving the current outbreak in the Democratic Republic of the Congo. Regeneron developed antibodies are now being tested in nonhuman primates with early data showing they can prevent mortality when administered even after clinical symptoms have already appeared. We are talking with the international health organizations to see whether we will be able to once again help with the current Ebola outbreak as we have in previous outbreaks. In summary, we remain focused on rapidly advancing our broad diverse pipeline, which we firmly believe has the potential to change the practice of medicine across many diseases with high unmet need. And with that, I'll turn it over to Marion.
