Thank you, Todd. Good afternoon, everyone. In the first quarter, we continue to make significant progress in our efforts to support young children and infants suffering from plaque psoriasis and atopic dermatitis. Starting first with atopic dermatitis, children under the age of 2 are the most vulnerable patients in a population that desperately needs alternative therapeutic options to the handful of currently available treatments. As a dermatologist, I can tell you firsthand how challenging it is to sufficiently address these diseases in this age group given the very limited set of approved therapies and how eager the parents and caregivers are for effective, safe and well-tolerated treatments to bring comfort to their kids. Safe, well-tolerated treatments are especially important in this age group when the immune system and the skin barrier are still developing. We take their plea very seriously, and we believe the clinical profile and formulation of ZORYVE are well suited to the needs of this young patient population. On our March call, we highlighted the positive top line data from the INTEGUMENT infant Phase II trial of ZORYVE cream 0.05% in infants aged 3 to less than 24 months with mild to moderate atopic dermatitis. Expanding on what we shared in March, we were honored to have our abstract selected for a prestigious late-breaker session and presented by Dr. Lawrence Eichenfield at the American Academy of Dermatology Annual Meeting at the end of March, select portions of which we have here on Slide 12. Over 1/3 of study participants who completed 4 weeks of treatment achieved a validated investigator global assessment for atopic dermatitis that's a VIGA-AD success. that's defined as a score of 0, which is clear, or 1, which is almost clear with at least a 2-grade improvement. Close to half of infants achieved a VIGA-AD score of clear or almost clear, that's a 0 or 1 at week 4 and 24% already at week 2. Now for those infants with at least mild scalp involvement at baseline, more than 2/3 achieved VIGA scalp success at week 4. And as previously highlighted, 58.3% of infants achieved at least a 75% reduction in their eczema area and severity index that's an EASI-75 at week 4 and 3/4 of infants already at week 2. Now to the right, we see a representative patient. This is a 23-month old boy who had previously been treated with topical corticosteroids with an IGA of 3 or moderate severity at baseline, and he's showing significant improvement at week 4 with an IGA of 1 or almost clear. I think these photos really represent the meaningful impact that our 0.05% cream delivered to patients in this study and why we're so excited to already have these data submitted to the FDA. Collectively, the findings from the INTEGUMENT infant study add important clinical evidence on the promise of investigational ZORYVE cream 0.05% in infants 3 to 24 months with rapid and robust efficacy across multiple clinical endpoints, coupled with excellent tolerability and a clean safety profile. Now moving on to Slide 13. I want to highlight one particularly notable result that we shared from INTEGUMENT infant at the AAD, namely the rapid impact that ZORYVE had on itch for these patients as reported by their caregiver. Itch is one of the most disruptive symptoms of atopic dermatitis in patients of all ages and the rapidity with which a therapy can alleviate itch is an important aspect of a drug's therapeutic profile. We've known since early clinical development that ZORYVE has a rapid impact on itch. The chart on the left-hand side of Slide 13 shows itch improvement over time in our registrational INTEGUMENT-1 and 2 trials in atopic dermatitis as measured by WI-NRS or worst itch numeric rating scale. As you can see, we saw itch reduction as early as 24 hours after first application, and that was the first time point measured in these trials. However, through our clinical trial experience and feedback from clinicians in the field, we appreciated that the speed with which ZORYVE impacts itch is exceptional. And with that in mind, in it taking an infant, we chose to measure impact on itch using the dynamic pruritus score, or DPS, with measurements as early as 10 minutes after application. The results from that analysis are demonstrated in the chart on the right-hand side of this slide. Nearly 50% of patients experienced a 25% improvement in itch as measured by their caregivers within just 10 minutes of application of ZORYVE and 2/3 of patients experienced relief within 4 hours. These results not only reinforce our conviction that ZORYVE will be an important therapeutic option for infant patients, but this demonstrated speed of onset has also prompted us to further study the impact of ZORYVE on itch. To that end, we recently initiated a study INTEGUMENT-Ich, to assess descriptive classification of pruritus over time with ZORYVE 0.15% cream in patients with atopic dermatitis. This 40-patient trial will begin enrolling shortly. We believe that the further validation of ZORYVE's rapid impact on itch that this trial is intended to demonstrate, particularly within the first 24 hours after initiating therapy is an important step in better understanding and articulating ZORYVE's profile in atopic dermatitis. INTEGUMENT itch is an example of our strategy to generate additional clinical data for our current indications to further bolster the data set behind ZORYVE. -- an important component of our growth strategy pillar. I look forward to sharing subsequent updates on other clinical activities we're pursuing along the same vein. Next, I'll provide an update on our label expansion efforts to support pediatric patient populations. As Frank mentioned in the opening, we submitted a supplemental NDA to the FDA in April for ZORYVE cream 0.05% to expand the indication to infants 3 to 24 months. We're thrilled to have taken this critical step to potentially bring a new safe, well-tolerated and effective therapeutic option to this patient population. It's notable that we were able to submit our application in just 3 months after having read out the top line results from our INTEGUMENT infant trial. This reflects the speed with which our team at Arcutis is moving on behalf of patients and our response to the high level of urgency shared by those HCPs who care for these youngest AD patients. Turning next to our pediatric expansion efforts for plaque psoriasis. We recently completed enrollment of a MUSE trial or maximum MUSE trial for ZORYVE foam 0.3% for children ages 2 to 11 years old with scalp and body psoriasis. The trial is intended to serve as the basis of an sNDA submission to extend the indication to this age group and to align the psoriasis indication of the 0.3% cream and foam. If approved, ZORYVE foam could offer a truly unique therapeutic option for caregivers helping their young children manage this disease that has historically been difficult to treat when presenting in hair-bearing areas. In addition, as previously announced, our supplemental NDA for ZORYVE cream 0.3% for psoriasis patients down to the age of 2 years is under review by the FDA and the PDUFA action date of June 29 is quickly approaching. I'll note that the rationale for extending our label to the infant population for atopic dermatitis does not apply to plaque psoriasis or seborrheic dermatitis. Onset of diseases in these patient populations is common in atopic dermatitis, while it's not in the other 2 diseases. Our current label in seborrheic dermatitis positions us to effectively serve the addressable patient population and potentially securing a label expansion to the pediatric age range in plaque psoriasis will similarly equip us to serve the addressable patient population. As demonstrated in the table on Slide 14, these latest developments in expanding our indications to additional pediatric and infant populations build on a consistent focus we've maintained over the years to broaden the availability of ZORYVE. We're driven by the need of these younger children for effective, safe and well-tolerated therapeutic alternatives to topical corticosteroids. We also anticipate that when health care providers see how effectively ZORYVE alleviates inflammatory skin disease in their most fragile and vulnerable patients, they'll be more inclined and appreciate the potential benefit from ZORYVE for their adult and adolescent patients with the same diseases. Now turning to Slide 15 and the pipeline. This is the build pillar of our strategy. We've now initiated the Phase I trial of ARQ-234, our novel biologic targeting CD200R in healthy volunteers and adults with moderate to severe atopic dermatitis. There's a clear and distinct need for a systemic therapy for patients with atopic dermatitis who have relapsed on or who are refractory to IL-4, IL-13 drugs. Many in the drug industry and many clinicians had until recently hoped that agents targeting OX40 would meet that need. However, after a series of disappointing clinical data sets and growing safety concerns for these programs targeting OX40 already leading to program discontinuations, that hope has dissipated, leaving a white space for novel new treatment pathways. It's our belief that the CD200 axis targeted by ARQ-234 could bring an important new tool for providers and an important new option for patients. The CD200 axis plays a central role in both innate and adaptive immunity with CD200 signaling reducing immune activation for T cells, type 2 innate lymphoid or ILC2 cells and myeloid cells and decreasing secretion of pro-inflammatory cytokines. Given the impact of this access, there's a solid basis for optimism about the role of CD200R agonist programs may play in treating inflammatory diseases. The Phase I trial for ARQ-234 is comprised of a single ascending dose or SAD component in healthy volunteers, which is currently ongoing and a multiple ascending dose or MAD component followed by a proof-of-concept cohort, both in patients with moderate to severe atopic dermatitis. While we will not share the results from the trial until completed, we will keep you apprised of our progress through these different components. Now moving on to Slide 16. As you can see, we've already delivered on several meaningful clinical milestones in 2026 and look forward to continuing clinical progress throughout the year. Of note, we continue to enroll our Phase II proof-of-concept trials in vitiligo and hidradenitis suppurativa or HS. We're nearing full enrollment for our vitiligo trial and remain on track to provide a readout of trial results and an update on our clinical development plan in Q4 of this year. And a similar readout for our HS program in Q1 of 2027 also remains on track. And Todd alluded earlier to the continued shift from topical steroids to advanced targeted topical therapies like ZORYVE. As we've mentioned on prior calls, we're seeing a steadily growing consensus within the dermatology specialty around the clinical needs for that shift, and we saw further evidence of this since the start of the year. On Slide 17, I highlight just a few of the recent discussions on this topic. I would call your attention in particular to one of the conclusions of the recently published expert consensus statement on advanced nonsteroidal topical therapies for atopic dermatitis, which came out in March in the Journal of Drugs in Dermatology. As you can see, some of the most distinguished experts in the field agree that advanced nonsteroidal topicals should be preferred over topical corticosteroids for long-term management of atopic dermatitis due to their cleaner safety profiles. This is typical of what we continue to hear from the leaders in dermatology, and this growing consensus will propel the conversion to the newer agents, of which ZORYVE is the leading treatment. With that, I'll turn the call over to Latha to further detail our Q1 financial results.
