Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic inflammatory skin disorder with limited treatment options for adolescents with moderate-to-severe disease. Lebrikizumab, a monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in previous Phase 3 trials: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), and ADhere (NCT04250337). We report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open-label study of lebrikizumab in adolescent patients with moderate-to-severe AD. The primary endpoint was to describe the proportion of patients who discontinued from study treatment because of adverse events (AEs) through the last treatment visit. METHODS Adolescent patients (N = 206) (≥ 12 to < 18 years old, weighing ≥ 40 kg) with moderate-to-severe AD received subcutaneous lebrikizumab 500 mg loading doses at baseline and Week 2, followed by 250 mg every 2 weeks (Q2W) thereafter. Safety was monitored using reported AEs, AEs leading to treatment discontinuation, vital signs, growth assessments, and laboratory testing. Efficacy analyses included Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Body Surface Area (BSA), (Children's) Dermatology Life Quality Index ((C)DLQI), and Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression. RESULTS 172 patients completed the treatment period. Low frequencies of SAEs (n = 5, 2.4%) and AEs leading to treatment discontinuation (n = 5, 2.4%) were reported. Overall, 134 patients (65%) reported at least one treatment-emergent AE (TEAE), most being mild or moderate in severity. In total, 62.6% achieved IGA (0,1) with ≥ 2-point improvement from baseline and 81.9% achieved EASI-75 by Week 52. The EASI mean percentage improvement from baseline to Week 52 was 86.0%. Mean BSA at baseline was 45.4%, decreasing to 8.4% by Week 52. Improvements in mean change from baseline (CFB) to Week 52 were observed in DLQI (baseline 12.3; CFB - 8.9), CDLQI (baseline 10.1; CFB - 6.5), PROMIS Anxiety (baseline 51.5; CFB - 6.3), and PROMIS Depression (baseline 49.3; CFB - 3.4) scores. CONCLUSIONS Lebrikizumab 250 mg Q2W had a safety profile consistent with previous trials and significantly improved AD symptoms and quality of life, with meaningful responses at Week 16 increasing by Week 52. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT04250350.

Abstract
BACKGROUND Interleukin-23 inhibitors are effective and safe for treating moderate-to-severe plaque psoriasis. OBJECTIVES To evaluate the efficacy and safety of mirikizumab in adult patients with moderate-to-severe plaque psoriasis through 52 weeks in a phase III randomized controlled trial. METHODS OASIS-1 (NCT03482011) was a double-blind, placebo-controlled, randomized withdrawal, phase III trial. Patients (n = 530, randomized 4 : 1) received subcutaneous mirikizumab 250 mg or placebo every 4 weeks (Q4W) through week 16. Coprimary endpoints were superiority of mirikizumab vs. placebo on static Physician's Global Assessment (sPGA; score of 0 or 1 with ≥ 2-point improvement) and ≥ 90% improvement in Psoriasis Area and Severity Index (PASI 90, responders) at week 16. Mirikizumab responders were rerandomized (1 : 1 : 1) to mirikizumab 250 mg every 8 weeks (Q8W), mirikizumab 125 mg Q8W, or placebo Q8W through week 52. Secondary endpoints were evaluated at weeks 16 and 52. Safety was monitored in all patients. RESULTS All primary and key secondary endpoints were met. At week 16, sPGA(0,1) responses were significantly greater with mirikizumab (293 of 423, 69·3%) than placebo (seven of 107, 6·5%) (P < 0·001). PASI 90 response was also greater with mirikizumab (272 of 423, 64·3%) than placebo (seven of 107, 6·5%) (P < 0·001). Significantly more patients in the mirikizumab arms achieved PASI 75 and PASI 100 (mirikizumab 349, 82·5% and 137, 32·4%; placebo 10, 9·3% and 1, 0·9%, respectively; all P < 0·001). At week 52, PASI 90, PASI 100 and sPGA(0,1) responses were mirikizumab 250Q4W/placeboQ8W (N = 91; 19%, 10%, 18%), mirikizumab 250Q4W/125Q8W (N = 90; 86%, 59%, 86%) and mirikizumab 250Q4W/250Q8W (N = 91; 86%, 60%, 82%; all P < 0·001), respectively. Rates of serious adverse events were similar across treatments (induction: mirikizumab 1·2% vs. placebo 1·9%; maintenance: mirikizumab 250Q4W/125Q8W 1%, mirikizumab 250Q4W/250Q8W 3% vs. placebo 3%). No deaths occurred. CONCLUSIONS Mirikizumab was superior to placebo at week 16 and maintained efficacy through week 52, with no new safety signals. What is already known about this topic? Interleukin (IL)-23 is a key cytokine in the pathogenesis of psoriasis. Drugs targeting the p19 subunit of IL-23 have recently been approved for the treatment of adult patients with moderate-to-severe plaque psoriasis. Patients with moderate-to-severe plaque psoriasis achieved significantly greater improvements in skin measures and patient-reported quality-of-life measures after 16 weeks when treated every 8 weeks with mirikizumab compared with placebo in a phase II clinical trial. What does this study add? Compared with placebo, mirikizumab demonstrated high levels of efficacy at week 16 in a large phase III trial; safety profiles were similar between the mirikizumab and placebo arms. After week 16, patients maintained on doses of mirikizumab 250 mg every 8 weeks (Q8W) or 125 mg Q8W showed similar efficacy and favourable safety profiles over 52 weeks, whereas patients switched to placebo gradually lost efficacy over time.

Abstract
AIMS Ixekizumab is a high-affinity monoclonal antibody that selectively targets interleukin-17A used in the treatment of adult and paediatric patients with moderate-to-severe psoriasis. This analysis evaluated the pharmacokinetics (PK) of ixekizumab and the exposure-efficacy relationship in paediatric patients aged 6 to <18 years with psoriasis. METHODS Population PK and exposure-efficacy models were developed. The models used data from paediatric patients with psoriasis participating in the Phase 3 IXORA-PEDS trial in which patients were dosed according to weight categories. The exposure-efficacy model is a Psoriasis Area and Severity Index (PASI) time course model using data up to Week 12, a co-primary efficacy endpoint. RESULTS A 2-compartment population PK model describes the PK of ixekizumab in paediatric patients with the effect of body weight incorporated on clearance and volume terms using an allometric relationship. The weight category-based dosing ensured that ixekizumab mean trough serum concentrations in paediatric patients with psoriasis (3.20-3.33 μg/mL) were within the range of concentrations observed in adult patients with psoriasis (mean [standard deviation]: 3.48 [2.16] μg/mL) administered an efficacious dosing regimen. The observed PASI response rates at Week 12 in paediatric patients (91.9/81.8/52.5% for PASI75/90/100) are well predicted by the final exposure-efficacy model and response rates are similar or higher than those achieved in adults (86.2/66.6/35.0% for PASI75/90/100). CONCLUSION This analysis is the first to describe the PK and exposure-efficacy relationship of ixekizumab in paediatric patients with psoriasis. The analyses support the selection of the weight category-based ixekizumab dosing regimens approved for use in paediatric patients with psoriasis.

Abstract
BACKGROUND/OBJECTIVES Information is limited on the relationship between skin clearance, resolution of challenging body areas, and improvement of patient-reported outcomes (PROs) in pediatric psoriasis. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for the treatment of moderate-to-severe psoriasis in patients aged 6 to <18 years. This study examines improvement in psoriasis clearance in challenging body areas in pediatric patients relative to health-related quality of life. METHODS Data from the IXORA-PEDS trial (NCT03073200) were analyzed, and changes from baseline were measured for overall Psoriasis Area and Severity Index (PASI), static Physicians' Global Assessment of psoriasis (sPGA), Psoriasis Scalp Severity Index (PSSI), Palmoplantar Psoriasis Area and Severity Index (PPASI), and Nail Psoriasis Severity Index. Rates of Dermatology Life Quality Index (DLQI), or Children's DLQI (CDLQI), scores of 0 or 1 were evaluated using the Cochran-Armitage trend test. RESULTS Higher rates of DLQI/CDLQI (0,1) scores were significantly associated with greater PASI and PSSI responses at both Week 12 and Week 48 (p < .0001). A significant association was also observed between DLQI/CDLQI (0,1) and sPGA scores (p < .0001). Significantly higher rates of DLQI/CDLQI (0,1) scores were achieved in patients with greater levels of palmoplantar clearance as measured by PPASI at Week 12 (p = .0139), but significance was not sustained at Week 48 (p = .0896). CONCLUSIONS Greater skin clearance and scalp resolution are associated with better PROs over a short-term (12-week) and long-term (48-week) period. This demonstrates that greater improvement of skin clearance and scalp resolution may benefit quality of life in pediatric patients with psoriasis.
