Tralokinumab and Topical Corticosteroids tied to sustained important in Atopic Dermatitis: ECZTRA 3 trial.
Over 32 weeks, it was found that continued use of tralokinumab treatment plus topical corticosteroids as needed provided progressive and sustained improvements in Atopic Dermatitis signs, symptoms, and health-related Quality of life as published in the journal, "American Journal of Clinical Dermatology, 2022."
Atopic dermatitis (AD) is a chronic inflammatory skin disease having a complex etiology leading to abnormalities in the epidermis and the immune system. Tralokinumab is a fully human monoclonal antibody that specifically neutralizes interleukin-13. The phase III ECZTRA 3 trial studied the efficacy and safety of tralokinumab with topical corticosteroids (TCS) as needed over 32 weeks. At Week 16, the primary endpoints of Investigator's Global Assessment (IGA) score of 0/1 and 75% improvement in Eczema Area and Severity Index (EASI-75) and all confirmatory endpoints were significantly achieved by tralokinumab- versus placebo-treated patients. So, researchers conducted a post hoc analysis to investigate the impact of tralokinumab plus TCS on AD severity, symptoms, and health-related quality of life (QoL) over the entire 32-week treatment period of ECZTRA 3, including all patients initiated on tralokinumab irrespective of the response achieved at Week 16.
Randomizing the participants to 2:1, to receive subcutaneous tralokinumab 300 mg or placebo every 2 weeks (q2w) with TCS as needed for an initial 16 weeks. At 16 weeks, patients who achieved the clinical response criteria were re-randomized 1:1 to tralokinumab q2w or every 4 weeks (q4w), with TCS as needed, for another 16 weeks. If they did not achieve the clinical response criteria, they were given tralokinumab q2w plus TCS from Week 16. All the participants randomized to tralokinumab in the initial treatment period were pooled for this analysis, irrespective of response.
