Key takeaways:
- The research included adolescents aged 12 to 17 years and adults.

Sufferers with atopic dermatitis skilled enhancements in severity with 16 weeks of tralokinumab regardless of the variety of atopic comorbidities that that they had, in line with information revealed in Annals of Allergy, Bronchial asthma & Immunology.
Not less than 60% of adolescents with moderate-to-severe AD have at the very least one atopic comorbidity, famous Amy S. Paller, MD, MS, Walter J. Hamlin Professor and Chair of Dermatology, professor of pediatrics and director of the Pores and skin Biology and Illnesses Useful resource-based Middle at Northwestern College’s Feinberg Faculty of Medication.

Knowledge derived from Paller AS KJ, et al. Ann Allergy Bronchial asthma Immunol. 2025;doi:10.1016/j.anai.2025.06.022.
Paller and colleagues studied adolescents and adults with AD who had at the very least one further comorbidity vs. those that did to not assess whether or not their response to tralokinumab was totally different.

“Tralokinumab (Adbry, LEO Pharma) was the second biologic accessible for individuals who are [aged] 12 and above with average to extreme atopic dermatitis,” Paller informed Healio.
In distinction to Dupilumab (Dupixent; Regeneron, Sanofi), the primary biologic authorised for AD, which targets the IL-4 receptor-IL-13 receptor heterodimer central to AD by inhibiting the IL-4 receptor, tralokinumab targets the IL-13 cytokine and thus doesn’t impression different IL-4 receptor-related signaling which may be concerned in different atopic responses.
“We nonetheless have no idea if tralokinumab may have a optimistic impression on different atopic illnesses as dupilumab can or if there are totally different responses based mostly on having different atopic comorbidities,” she stated.
The research included information from 4 section 3, multinational, double-blind, randomized, placebo-controlled medical trials of sufferers with average to extreme AD who acquired doses each 2 weeks throughout 16 weeks.
In ECZTRA 1 and a pair of, adults acquired 300 mg of tralokinumab or placebo in a 3:1 ratio. Adults in ECZTRA 3 acquired 300 mg of tralokinumab or placebo with topical corticosteroids as wanted in a 2:1 ratio. Adolescents aged 12 to 17 years in ECZTRA 6 acquired 150 mg or 300 mg of tralokinumab or placebo in a 1:1:1 ratio.
Most sufferers had at the very least one comorbidity, together with 79% of these in ECZTRA 1 and a pair of (n = 1,244), 84% in ECZTRA 3 (n = 306) and 87% in ECZTRA 6 (n = 251).
Comorbidities included bronchial asthma (ECZTRA 1 and a pair of, 51%; ECZTRA 3, 60%; ECZTRA 6, 51%), meals allergy (ECZTRA 1 and a pair of, 38%; ECZTRA 3, 40%; ECZTRA 6, 57%), hay fever (ECZTRA 1 and a pair of, 54%; ECZTRA 3, 61%; ECZTRA 6, 68%) and allergic conjunctivitis (ECZTRA 1 and a pair of, 33%; ECZTRA 3, 35%; ECZTRA 6, 34%).
At baseline, illness severity was better for sufferers with at the very least one comorbidity in contrast with those that had no comorbidities, the researchers stated, based mostly on Investigator International Evaluation (IGA), Eczema Space and Severity Index (EASI), SCORing Atopic Dermatitis (SCORAD), Dermatology Life High quality Index (DLQI) and Youngsters’s DLQI (CDLQI).
At week 16, the researchers stated, extra sufferers within the remedy teams achieved a 75% or better enchancment of their EASI scores (EASI75), an IGA rating of 0 or 1 and an enchancment of 4 factors or better in worst day by day pruritus Numeric Score Scale scores than within the placebo teams no matter whether or not they had any atopic comorbidities at baseline, with no statistically important variations between these with or with out comorbidities.
For instance, 35.3% of these with bronchial asthma and 35.1% of those that didn’t have bronchial asthma within the remedy group and 12.8% of these with bronchial asthma and 19.5% of those that didn’t have bronchial asthma within the placebo group achieved EASI75 in ECZTRA 1 and a pair of.
In ECZTRA 6, 16.8% of these with meals allergy and 29.9% of these with no meals allergy within the remedy group and three.8% of these with meals allergy and seven.5% of these with no meals allergy within the placebo group achieved an IGA rating of 0 or 1.
Additionally, extra adults achieved a 4 level or better enchancment in DLQI scores with tralokinumab in contrast with placebo, once more whatever the presence of any comorbidities, the researchers continued.
Sufferers in ECZTRA 3 included 43.9% with hay fever and 54.9% with no hay fever within the remedy group in addition to 27.5% with hay fever and 48% with no hay fever within the placebo group who had 4 factors or extra of enchancment in worst day by day pruritus NRS scores.
Proportions of adolescents whose CDLQI scores elevated by six factors or greater with tralokinumab throughout comorbidity classes had been comparable as properly, the researchers added, together with equal response amongst sufferers with at the very least one comorbidity within the remedy and placebo teams. Sleep NRS scores improved by three factors or extra for extra adults and adolescents alike with tralokinumab than with placebo no matter whether or not they had comorbidities or not as properly.
“There isn’t any distinction. Each teams did simply as properly,” Paller stated. “That was very reassuring for our sufferers who’ve further atopic issues, which was nearly all of sufferers within the research.”
Paller additionally stated that tralokinumab and dupilumab have “very related” security profiles, which she referred to as reassuring.
“There actually aren’t many uncomfortable side effects with dupilumab,” she stated, noting the chance primarily of injection web site reactions and a few ocular irritation. “These are each comparatively low-frequency occasions, and it appears to be the identical with tralokinumab.”
The researchers categorized a lot of the antagonistic occasions in the course of the trials as delicate or average with low charges of great and different antagonistic occasions that led to discontinuation of the drug throughout sufferers each with and with out comorbidities.
Nonetheless, there was a better variety of sufferers with antagonistic occasions throughout the remedy and placebo teams among the many sufferers with at the very least one comorbidity, in contrast with these sufferers who didn’t have any comorbidities.
“That is to be anticipated,” stated Paller, “since antagonistic occasions reported in a trial wouldn’t have to narrate to the research drug however simply globally replicate medical points that come up, and sufferers with comorbidities in a trial will probably have extra antagonistic occasions.”
The comorbidity group had a better proportion of sufferers with bronchial asthma antagonistic occasions, which means their bronchial asthma received worse since baseline, in contrast with the group with no comorbidities.
However throughout the comorbidity group, those that used tralokinumab had a decrease proportion of sufferers with bronchial asthma antagonistic occasions than these on placebo, suggesting some potential impression on bronchial asthma.
Lastly, there have been extra adults within the remedy and placebo teams with at the very least one comorbidity who had conjunctivitis antagonistic occasions, in contrast with the adults who didn’t have any comorbidities. There have been no conjunctivitis antagonistic occasions amongst any of the adolescent sufferers.
“We don’t but have sufficient information factors to match the danger of ocular floor antagonistic occasions vs. with dupilumab, however we all know anecdotally that sufferers can response to at least one drug and never one other,” Paller stated.
“That is an alternative choice that appears to be very secure for sufferers who have to get off of dupilumab if [they have] an antagonistic occasion or inadequate effectiveness,” she added. “It doesn’t matter if they’ve a number of different comorbid atopic illnesses. They need to nonetheless do properly with this drug with none elevated threat of further uncomfortable side effects.”
Based mostly on these findings, the researchers concluded that AD improved with 16 weeks of remedy with tralokinumab, in contrast with placebo, regardless of the presence of atopic comorbidities.
Subsequent, Paller stated, analysis ought to concentrate on growing a greater understanding of how properly tralokinumab performs for sufferers who’re proof against dupilumab. Changes in dosing must be explored as properly, she added, together with reductions and even suspension of remedy. After 16 weeks, she stated, half the sufferers who had been doing properly with tralokinumab moved to month-to-month doses, and greater than half of them noticed continued optimistic outcomes for 52 weeks.
“That’s fairly thrilling as properly,” Paller stated.
