BALLERUP, Denmark, 28 February 2018 – LEO Pharma has today announced that it has enrolled the first patients in a third phase 3 clinical study of tralokinumab, an investigational, fully human monoclonal antibody for the treatment of moderate-to-severe atopic dermatitis. Tralokinumab specifically blocks the effects of the cytokine IL-131, which plays a central role in the development of atopic dermatitis2,3 – one of the most common chronic, inflammatory skin diseases4. Tralokinumab is not currently licensed in any country for any indication.
ECZTRA 3 (ECZema TRAlokinumab trial no. 3), is a randomized, double-blind, placebo-controlled, phase 3 trial to evaluate the efficacy and safety of tralokinumab in combination with topical corticosteroids (TCS) in patients with moderate to severe atopic dermatitis who are candidates for systemic therapy.
"Topical steroids are commonly used to treat acute flares or lesions caused by atopic dermatitis, while biologics help maintain long-term control of persistent, immune-mediated inflammation,” said Jonathan Silverberg, MD, PhD, Assistant Professor of Dermatology, Northwestern University Feinberg School of Medicine, Chicago, Illinois. “Patients with moderate-to-severe atopic dermatitis may require both types of therapies to achieve the best results, so it’s important to understand how treatments that specifically target IL-13 alone, in combination with topical corticosteroids, can help, in combination with topical corticosteroids, can help patients in the real world with such a chronic and complex skin disease.”

NOTE TO EDITORS
About Atopic Dermatitis (AD)
AD is a common type of eczema that affects up to 10 percent of adults5. It is a chronic, intensely pruritic (itching of the skin without visible eruption) skin disease, characterized by persistent, immune-mediated inflammation and skin barrier defects6. AD has a significant, negative impact on patient well-being primarily due to the intense itch which leads to disrupted sleep and other negative consequences. There is currently a high unmet need for long-term efficacious and well-tolerated treatment options in atopic dermatitis.7
