Administered subcutaneously, tralokinumab is a fully human IgG4 monoclonal antibody that specifically binds to interleukin-13, a key driver of underlying inflammation in AD. The drug, which has been developed by LEO Pharma, comes as a single-dose (150 mg) prefilled syringe with needle guard.
In two pivotal phase 3 trials, ECZTRA 1 and ECZTRA 2, tralokinumab monotherapy was superior to placebo at week 16 for all primary and secondary endpoints. For example, at week 16, for the ECZTRA 1 and 2 monotherapy trials, respectively, 16% and 21% of patients treated with tralokinumab 300 mg every other week achieved clear or almost clear skin (IGA 0/1) versus 7% and 9% with placebo.
In addition, 25% and 33% of patients treated with tralokinumab 300 mg every other week achieved an improvement of 75% or more in the Eczema Area and Severity Index score (EASI-75) versus 13% and 10% with placebo. At 52 weeks, 51% and 60% of patients who responded at week 16 maintained IGA 0/1 response with tralokinumab 300 mg every other week in ECZTRA 1 and 2, respectively.

Finally, 60% and 57% of patients who responded at week 16 maintained EASI-75 response with tralokinumab 300 mg every other week.
In the drug’s third pivotal trial, ECZTRA 3, researchers evaluated the efficacy and safety of tralokinumab 300 mg in combination with topical corticosteroids (TCS) as needed in adults with moderate to severe atopic dermatitis who are candidates for systemic therapy. At week 16, 38% of patients treated with tralokinumab 300 mg every other week plus TCS achieved clear or almost clear skin (IGA 0/1) versus 27% with placebo plus TCS. In addition, 56% of patients treated with tralokinumab 300 mg every other week plus TCS achieved an improvement of 75% or more in the EASI-75 versus 37% with placebo plus TCS. At 32 weeks, 89% and 92% of patients who responded at week 16 maintained response (IGA 0/1 and EASI-75, respectively) with tralokinumab 300 mg every other week.
