LEO Pharma receives positive CHMP opinion of Adtralza® (tralokinumab) for the treatment of adults with moderate-to-severe atopic dermatitis

BALLERUP, Denmark, 23 APRIL, 2021 – LEO Pharma A/S, a global leader in medical dermatology, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion and recommended granting a marketing authorization of Adtralza^® (tralokinumab) for the treatment of moderate-to-severe atopic dermatitis in adult patients who are candidates for systemic therapy.

The CHMP positive opinion is one of the final steps before the European Commission makes its decision on the Marketing Authorization Application for use of Adtralza, an investigational therapy in clinical development, throughout the European Union. This final decision is expected in the coming months and if authorized, Adtralza will be the first fully human, monoclonal antibody available to specifically target the IL-13 cytokine, a key driver of atopic dermatitis signs and symptoms. Adtralza specifically targets IL-13 with high affinity and is developed to improve the symptoms of atopic dermatitis, which is a complex and chronic inflammatory skin condition.^1,2

“Atopic dermatitis is characterized by its unpredictability, which can be challenging for patients who often experience physical discomfort and emotional effects that may continue for decades,”said Jörg Möller, Executive Vice President, Global Research and Development, LEO Pharma. “Today’s CHMP opinion brings LEO Pharma one step closer to the potential of providing Adtralza as a new therapeutic option for EU patients living with moderate-to-severe atopic dermatitis.”

Pending the final decision from the European Commission, the marketing authorization will be valid in all European Union Member States, Iceland, Norway, and Liechtenstein. Additional regulatory filings are underway [with the U.S. Food and Drug Administration (FDA)] and other health authorities worldwide.

 

About Adtralza (tralokinumab)

Adtralza (tralokinumab) is a fully human, monoclonal antibody developed to specifically neutralize the IL-13 cytokine, which plays a key role in the immune process underlying atopic dermatitis signs and symptoms. Adtralza specifically binds to the IL-13 cytokine with high affinity, thereby preventing interaction with the IL-13 receptor α1 and α2 subunits (IL-13Rα1 and IL-13Rα2).^1,2

About the pivotal ECZTRA 1, 2, and ECZTRA 3 Trials
ECZTRA 1 and ECZTRA 2 (ECZema TRAlokinumab trials Nos. 1 and 2) were randomized, double-blind, placebo-controlled, multinational 52-week trials, which included 802 and 794 adult patients, respectively, to evaluate the safety and efficacy of Adtralza (300 mg) as monotherapy in adults with moderate-to-severe atopic dermatitis who were candidates for systemic therapy.³

ECZTRA 3 (ECZema TRAlokinumab trial No. 3) was a double-blind, randomized, placebo-controlled, multinational 32-week trial, which included 380 adult patients, to evaluate the safety and efficacy of Adtralza (300 mg) in combination with TCS in adults with moderate-to-severe atopic dermatitis who are candidates for systemic therapy.⁴

About atopic dermatitis
Atopic dermatitis (AD) is a chronic, inflammatory, skin disease characterized by intense itch and eczematous lesions.⁵ Atopic dermatitis is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation.⁶ Type 2 cytokines, including IL-13, play a central role in the key aspects of atopic dermatitis pathophysiology.¹
