Atopic Dermatitis

Key clinical point: Baricitinib could serve as an effective treatment option for patients with difficult-to-treat moderate-to-severe atopic dermatitis (AD), including those unresponsive to dupilumab treatment; however, a high discontinuation rate indicates its rather heterogenous efficacy.

Major finding: At week 16, the mean Eczema Area and Severity Index score and numerical rating scale-pruritis significantly decreased from 18.3 to 11.1 (P < .0001) and from 6.6 to 5.3 (P < .0001), respectively. The most frequent adverse events (AE) were nausea (11.8%), urinary tract infection (9.8%), and herpes simplex infections (7.8%). Baricitinib treatment was discontinued by 43.2% of patients due to ineffectiveness or AE.

Study details: This multicenter prospective observational study included 51 adult patients with moderate-to-severe AD from the BioDay registry who received baricitinib over 16 weeks.

Disclosures: This study did not report a source of funding. Some authors declared serving as speakers, consultants, advisory board members, or investigators for various organizations.

Key clinical point: Downtitrated baricitinib treatment was efficacious in most patients with moderate-to-severe atopic dermatitis (AD) through 16 weeks; clinically relevant efficacy was observed in most patients who were readministered the original dose due to downtitration or treatment withdrawal-related efficacy loss.

Major finding: In the 4-mg and 2-mg cohorts, 61% and 71% of patients maintained a validated Investigator’s Global Assessment for AD (vIGA-AD) score of 0/1/2 at downtitration week 16 and 80%/85%/88% and 90%/56%/86% of patients who switched to original dose in the continuous dosing/downtitration/treatment withdrawal group re-achieved vIGA-AD 0/1/2, respectively.

Study details: This BREEZE-AD3 trial substudy included 526 patients with moderate-to-severe AD treated with 4/2 mg baricitinib at trial entry who achieved vIGA-AD 0/1/2 at week 52, with each cohort being re-assigned to continuous dosing, downtitration, or treatment withdrawal.

Key clinical point: Dupilumab decreases disease severity, disease-associated symptoms, and severity-associated serum biomarker levels in pediatric patients with atopic dermatitis (AD) in daily practice.

Major finding: At week 28, 49.2% of patients achieved Eczema Area and Severity Index-75; 84.7%, 45.3%, and 77.4% achieved a ≥4-point improvement in the Patient-Oriented Eczema Measure, Numeric Rating Scale (NRS)-pruritus, and NRS-pain scores, respectively; 36.1% scored clear or almost clear on the Investigator’s Global Assessment. The levels of severity-associated markers soluble IL-2-receptor alpha (P < .05), periostin (P < .05), thymus- and activation-regulated chemokine (P < .005), and pulmonary- and activation-regulated chemokine (P < .005) were significantly reduced at week 4. Conjunctivitis (16.4%) and headache (6.6%) were the most common side effects.

Study details: This multicenter prospective observational study included 61 patients (children ≥6 to <12 years; adolescents ≥12 to <18 years) from the BioDay registry with moderate-to-severe AD who received dupilumab for 28 weeks.

Key clinical point: Specific targeting of interleukin-13 alone with tralokinumab improved microbial diversity and reduced Staphylococcus aureus abundance in the lesional skin in patients with moderate-to-severe atopic dermatitis (AD).

Major finding: The 16-week tralokinumab treatment reduced S. aureus abundance by 20.7-fold (P < .0001), whereas placebo led to a non-statistically significant reduction. Tralokinumab also led to a significant increase in microbial diversity as early as week 8 (P < .001) and also at week 16 (P < .05).

Study details: The data come from the phase 3 ECZTRA 1 trial including 802 patients with moderate-to-severe AD who were randomly assigned to receive 300 mg subcutaneous tralokinumab or placebo.

Disclosures: This study and the ECZTRA 1 trial were funded by LEO Pharma A/S. Some authors declared serving as speakers, consultants, investigators, scientific advisors, or clinical study investigators or receiving institutional research grants from various sources, including LEO Pharma.

Key clinical point: An exposure to topical calcineurin inhibitors did not increase the risk for cancer in patients with atopic dermatitis (AD), with findings being similar among infants, children, and adults.

Major finding: Compared with no exposure, topical calcineurin inhibitor exposure was not associated with an increased risk for cancer (odds ratio [OR] 1.03; 95% credible interval [CrI] 0.94-1.11), with neither pimecrolimus (OR 1.05; 95% CrI 0.94-1.15) nor tacrolimus (OR 0.99; 95% CrI 0.89-1.09) use revealing any association with increased cancer risk, across all age groups.

Study details: This was a systematic review and meta-analysis of 110 unique studies (52 randomized controlled trials and 69 nonrandomized studies) including 3.4 million patients with AD followed-up for a mean of 11 months.

Key clinical point: Treatment with rocatinlimab, a novel monoclonal antibody, significantly improved disease severity at all dosing regimens in patients with moderate-to-severe atopic dermatitis (AD) inadequately controlled with topical therapy, which was maintained in most patients even after treatment discontinuation.

Major finding: The least-squares mean percent reductions in the Eczema Area and Severity Index at week 16 were significantly greater with 150 mg rocatinlimab every 4 weeks vs placebo (−48.3% vs −15.0%; P  =  .0003), with all other active rocatinlimab dose regimens vs placebo showing improvement (all P < .05) and most patients showing sustained response during off-drug follow-up.

Study details: The data come from a multicenter phase 2b study including 274 patients with moderate-to-severe AD and inadequate response or intolerance to topical medications and who were randomly assigned to receive rocatinlimab or placebo.

Disclosures: This study was funded by Kyowa Kirin. Some authors reported ties with various sources, including Kyowa Kirin. E Esfandiari declared being an employee of Kyowa Kirin.
