Key clinical point: Treatment with 15 mg or 30 mg upadacitinib demonstrated rapid and durable improvements in symptoms and quality of life in adults with moderate to severe atopic dermatitis (AD), based on a treat-to-target approach.

Major finding: Overall, >80%, >78%, and ≥87% of patients achieved the 3-month initial acceptable target, whereas ≥53%, >61%, and >73% of patients achieved the 6-month optimal target goal with 15 mg or 30 mg upadacitinib vs placebo at weeks 2, 16, and 52, respectively. The proportion of patients achieving a higher number of individual target criteria increased over time for both 3- and 6-month target goals.

Study details: This treat-to-target analysis of Measure Up 1 and Measure Up 2 phase 3 studies included 1282 adults with moderate to severe AD who were randomly assigned to receive 15 mg upadacitinib (n = 428), 30 mg upadacitinib (n = 424), or placebo (n = 430).

Disclosures: This study was funded by AbbVie. Five authors declared being employees of AbbVie or holding AbbVie stock, stock options, or patents. Several authors declared having ties with various sources, including AbbVie.

Key clinical point: Dupilumab treatment was well-tolerated and demonstrated improved clinical and molecular responses in pediatric patients with moderate to severe atopic dermatitis (AD).

Major finding: Dupilumab significantly reduced Eczema Area and Severity Index, SCORing Atopic Dermatitis index, and Investigator’s Global Assessment scores at 3 and 6 months (all P < .05), along with significant reduction in AD-associated stratum corneum biomarker levels at 3 months (P < .01). Dupilumab showed good tolerability, with adverse events reported in only four patients.

Study details: This study included 314 pediatric patients with moderate to severe AD from the German TREATkids registry, of whom 87 received dupilumab.

Key clinical point: Lebrikizumab monotherapy rapidly and consistently reduced atopic dermatitis (AD) extent and severity in patients with moderate to severe AD across all Eczema Area and Severity Index (EASI) clinical signs and body regions.

Major finding: At week 16, lebrikizumab vs placebo led to greater improvements in EASI scores and clinical signs (both P < .001) across all body regions in ADvocate1 and ADvocate2, with improvements observed as early as week 2 for all signs except erythema on head/neck (P < .05) and lower extremity erythema, edema/papulation, and lichenification (all P < .001), which improved significantly only by week 4 in ADvocate2.

Study details: This post hoc analysis of ADvocate1 (n = 424) and ADvocate2 (n = 427) included adolescent and adult patients with moderate to severe AD who were randomly assigned to receive 250 mg lebrikizumab biweekly or placebo.

Study details: This cohort study analyzed the data on AD-associated single nucleotide polymorphisms of patients with AD (n = 15,208) and control individuals without AD (n = 367,046) from the FinnGen database (10^th release) and the summary data of patients with brain cancer (n = 606) and control individuals without cancer (n = 372,016) from the IEU Open GWAS database.

Disclosures: This study did not disclose any funding source. The authors declared no conflicts of interest.

Key clinical point: Maternal probiotic supplementation was effective in preventing atopic dermatitis (AD) in children regardless of their filaggrin (FLG) gene mutation status.

Major finding: Heterozygous FLG mutations were observed in 7% of children. The risk for AD after maternal probiotic supplementation was similar between children who expressed a FLG mutation (risk ratio [RR] 0.6; 95% CI 0.1-4.1) and those having a wild-type FLG (RR 0.6; 95% CI 0.4-0.9).

Study details: This exploratory study included the data of 228 children from the Probiotic in the Prevention of Allergy among Children in Trondheim (ProPACT) study who did or did not have FLG mutations and whose mothers received probiotic or placebo milk from 36 weeks of gestation until 3 months post delivery while breastfeeding.

Key clinical point: When combined with topical corticosteroids (TCS), tralokinumab and dupilumab demonstrate similar efficacy in the treatment of patients with moderate to severe atopic dermatitis (AD) at 32 weeks of therapy.

Major finding: At week 32, tralokinumab and dupilumab treatment, both in combination with TCS, led to a similar proportion of patients achieving an Investigator's Global Assessment score of 0 or 1 (49.9% vs 39.3%; P = .95) or 75% improvement in the Eczema Area Severity Index scores (71.5% vs 71.9%; P = .95).

Study details: This unanchored matching-adjusted indirect comparison study analyzed the individual patient data of adults with moderate to severe AD (sample size 123.4) treated with tralokinumab plus TCS in ECZTRA 3, which were matched with the aggregate data of 106 patients treated with dupilumab plus TCS in the LIBERTY AD CHRONOS trial.

Key clinical point: Topical 1.5% ruxolitinib was effective and well-tolerated and offered long-term disease control with as-needed use in adolescents with atopic dermatitis (AD).

Major finding: At week 8, a substantially higher number of patients receiving 1.5% ruxolitinib vs vehicle achieved an Investigator's Global Assessment (IGA) score of 0 or 1 with ≥2 grade improvement from baseline (50.6% vs 14.0%) and ≥75% improvement in the Eczema Area and Severity Index score (60.9% vs 34.9%), with sustained or increased proportion of patients achieving an IGA score of 0 or 1 during the long-term safety (LTS) period. No serious adverse events were reported.

Study details: This study used pooled data from two phase 3 trials (TRuE-AD1 and TRuE-AD2) and included 137 adolescents (age, 12-17 years) with AD who were randomly assigned to receive 0.75% or 1.5% ruxolitinib cream or vehicle twice daily for 8 weeks, followed by an LTS period lasting up to 52 weeks.

Key clinical point: Topical 1.5% ruxolitinib was effective and well-tolerated and offered long-term disease control with as-needed use in adolescents with atopic dermatitis (AD).

Major finding: At week 8, a substantially higher number of patients receiving 1.5% ruxolitinib vs vehicle achieved an Investigator's Global Assessment (IGA) score of 0 or 1 with ≥2 grade improvement from baseline (50.6% vs 14.0%) and ≥75% improvement in the Eczema Area and Severity Index score (60.9% vs 34.9%), with sustained or increased proportion of patients achieving an IGA score of 0 or 1 during the long-term safety (LTS) period. No serious adverse events were reported.

Key clinical point: Obesity is significantly associated with patient- and physician-assessed measures of atopic dermatitis (AD) disease severity.

Major finding: Increased body mass index (BMI) values were associated with higher disease severity as assessed by objective Scoring AD (adjusted β 1.24; P = .013) and patient-oriented eczema measure (adjusted β 1.09; P = .038) scores.

Study details: This study based on data from the prospective observational TREATgermany registry included 1416 patients with moderate to severe AD who were either underweight (BMI < 18.5 kg/m²; n = 33), normal weight or overweight (nonobese; BMI ≥ 18.5 and < 30 kg/m²; n = 1149), or obese (BMI ≥ 30 kg/m²; n = 234).

Key clinical point: Antibiotic use early in life, especially within one year of age, disrupts the gut microbiome and increases the risk for atopic dermatitis (AD) at 5 years of age.

Major finding: Children who received antibiotics during the first year of life vs later were significantly more likely to develop AD at 5 years of age (adjusted odds ratio [aOR] 1.81; P < .001), with an increased number of antibiotic courses leading to a dose-response-like increased risk for AD (1 course: aOR 1.67; P = .0044; ≥ 2 courses: aOR 2.16; P = .0030).

Study details: This study analyzed the clinical data for AD diagnosis at age 5 years of 2484 children from the prospective, general population CHILD birth cohort, which enrolled pregnant women and infants with no congenital abnormalities born at ≥ 34 weeks of gestation.

Disclosures: The CHILD Study is funded by the Canadian Institutes of Health Research, the Allergy, Genes, and Environment Network of Centres of Excellence, Debbie and Don Morrison, and others. The authors declared no conflicts of interest.
