Thank you, Sanj. The growing understanding of recurrent pericarditis being driven by the cytokines, interleukin-1 alpha and beta has been a key driver behind the growth we've seen in the adoption of ARCALYST. As an increasing number of health care professionals update their approach to how to treat recurrent pericarditis with targeted IL-1 immunomodulation, we've seen a substantial increase in the number of active commercial patients on ARCALYST. Specifically, this is a result of our team driving increases in 2 key areas. Firstly, in Q3, new patient enrollments grew by their highest level in a quarter since launch. This is represented in the growth of prescribers of more than 350 in the quarter, leading to a total prescriber count launched to date of more than 3,825, including around 28% or more than 1,000 prescribers who have written ARCALYST for 2 or more patients. Secondly, once on treatment, patients are staying on ARCALYST for longer, which speaks to both the duration of the disease and patient satisfaction on ARCALYST. At the end of Q3, the total average duration of therapy increased to approximately 32 months. These two levers increased the number of active commercial patients and contributed to our ability to raise our revenue guidance for the full year 2025. Our commercial organization has been highly focused on evolving the treatment landscape for patients suffering from this chronic, highly debilitating disease by increasing education and driving the utilization of interleukin-1 alpha and beta inhibition towards becoming the new standard of care for recurrent pericarditis. We have built a highly effective commercial infrastructure and built upon many years of established relationships with the recurrent pericarditis community to improve the care for patients. In the 4.5 years since the launch of ARCALYST, we've continued to hone our messaging and we've improved our effectiveness through utilization of AI and digital marketing to inform which physicians to visit and importantly, when they're most likely to see a recurrent pericarditis patient. Thanks to the compelling clinical and real-world data generated in RHAPSODY and RESONANCE, our payer approval rate remains very high, and we continue to be focused on delivering excellent support to patients through Kiniksa OneConnect, our patient services program. This combination of robust data, access and support enables health care professionals to feel confident that their patients will get on to therapy, be well supported and receive the type of efficacy we've seen in the published literature. As a result of the continued growth in patients on ARCALYST, today, we raised and tightened our full year 2025 ARCALYST net sales guidance from between $625 million to $640 million to now between $670 million and $675 million, which is a $40 million increase in guidance between the midpoints. Our increased guidance reflects the robust trajectory of ARCALYST revenue in 2025, while also accounting for typical year-end industry dynamics, which is consistent with our historical fourth quarter performance. As you've heard, we're pleased with our solid execution and progress and are incredibly excited about the opportunities we have ahead. As we continue to focus on maximizing the growth of ARCALYST, we are also excited about the opportunity to advance the care of recurrent pericarditis patients in the future with KPL-387, our development program. This is our fully owned monoclonal antibody antagonist targeting the IL-1 receptor to inhibit both IL-1 alpha and beta. The totality of data show that inhibiting the activity of both of these key cytokines is a core component of delivering a highly efficacious treatment for recurrent pericarditis. With this program, we're advancing a validated mechanism with the potential to address key patient needs and expand penetration into the addressable market by enabling a convenient monthly subcutaneous dose in an auto-injector. Surveyed patients and health care professionals have indicated a preference for a highly efficacious IL-1 alpha and beta inhibitor with this target profile. Specifically, approximately 75% of all surveyed recurrent pericarditis patients report that they would prefer the KPL-387 target profile over those of available commercial and current investigational therapies. On the physician side, more than 90% of health care professionals stated a high likelihood of prescribing KPL-387 for new patients as well as being receptive to switching current patients upon a patient's request. It's also worth noting that health care professionals broadly agree that the introduction of KPL-387 would expand the IL-1 alpha and beta inhibition market overall. As we've previously announced, the dose focusing portion of the Phase II/III development program of KPL-387 is currently underway, and we expect those data in the second half of 2026. With that, I'll turn the call over to Mark Ragosa to review our third quarter financials. Mark?
