Tralokinumab has received a positive opinion from the European Medicine Agency’s Committee for Medicinal Products for Human Use to extend use to adolescents aged 12 years and older with moderate-to-severe atopic dermatitis (AD) who are candidates for systemic therapy, according to a statement from the manufacturer.
The positive CHMP opinion, issued on Sept. 15, recommends extending the use of tralokinumab (Adtralza), an interleukin-13 antagonist, to adolescents aged 12-17 years in the EU. The positive opinion recommends an initial dose of 600 mg administered subcutaneously followed by 300 mg every other week, the dosing recommended for adults.
In December 2021, tralokinumab was approved for adults with moderate to severe AD in the United States, where it is marketed as Adbry. It is also approved for adults in the EU, Great Britain, Canada, the United Arab Emirates, and Switzerland. It is not currently approved for treatment of adolescents in any country, according to the LEO Pharma statement.
A regulatory filing with the U.S. Food and Drug Administration is in progress, the company said, and an additional study of tralokinumab for individuals aged 12 years and older is underway, according to the manufacturer.
The CHMP opinion was supported by data from a phase 3 study (ECZTRA 6) that assessed safety and efficacy of 150-mg or 300-mg doses of tralokinumab, compared with placebo in adolescents with moderate-to-severe AD, the company statement said. The primary outcomes were an Investigator Global Assessment score of clear or almost clear skin (IGA 0/1) and an improvement of at least a 75% on the Eczema Area and Severity Index score (EASI-75). In the study, presented as a poster at a meeting in October 2021, a total of 195 adolescents aged 12-17 with moderate to severe AD who were candidates for systemic therapy were randomly assigned to tralokinumab and 94 to placebo.
At 16 weeks, 21.4% and 17.5% of patients who received 150 mg and 300 mg, respectively, of tralokinumab had IGA scores of 0 or 1, compared with 4.3% of those on placebo (P < .001, P = .002, respectively vs. placebo). In addition, 28.6% and 27.8% of the 150-mg and 300-mg tralokinumab groups, respectively, achieved EASI-75, compared with 6.4% of placebo patients (P < .001, P = .001, respectively, compared with placebo).
Adverse events were similar between the groups, and most were mild or moderate; overall safety profiles were similar to those seen in adult patients.
The European Commission will review the positive opinion and make a final decision.
