DefinitionThis section has been translated automatically.
Tralokinumab is a human monoclonal IgG4 antibody that, unlike Dupilumab, binds specifically to the interleukin-13 cytokine (IL-13). IL-13 plays an essential role in the pathogenesis of atopic dermatitis and bronchial asthma. Blocking IL-13 inhibits the interaction with the receptor and prevents the subsequent downstream IL-13 signal transmission. The therapeutic success with tralokinumab in atopic dermatitis (but not in asthma) supports the hypothesis that blocking the cytokine IL-13 alone is sufficient to improve the symptoms of atopic dermatitis.

Asthma: Tralokinumab was primarily developed for the treatment of severe, uncontrolled asthma. The efficacy and safety of tralokinumab has not been adequately demonstrated. Further testing in this clinical picture was therefore discontinued (Panettieri RA Jr et al. 2018).
Atopic dermatitis: In contrast, tralokinumab rapidly and persistently relieved the symptoms of atopic dermatitis in a phase II study (Wollenberg A et al. 2019). Tralokinumab has shown good efficacy both as monotherapy and in combination with topical corticosteroids in adults with moderate to severe atopic dermatitis.
In June 2018, a Phase IIb study was published showing that the monoclonal antibody tralokinumab successfully relieved symptoms in patients with moderate to severe AD. This study also investigated the effect of tralokinumab on health-related quality of life compared to placebo in 52 adult patients. Patients treated with the antibody showed statistically significant and clinically relevant improvements over placebo in almost all aspects of health-related quality of life from week 12 onwards (Silverberg J et al. 2018).
Tralokinumab has not yet been approved.
