LEO Pharma Announces Publication of Adbry™ (tralokinumab-ldrm) Efficacy Data in Moderate to Severe Atopic Dermatitis in the American Journal of Clinical Dermatology

MADISON, NJ–(BUSINESS WIRE)–LEO Pharma A/S, a global leader in medical dermatology, today announced that American Journal of Clinical Dermatology published the 32-week results of a post-hoc analysis of the ECZTRA 3 Phase 3 clinical trial (NCT03363854) in atopic dermatitis (AD). Analysis showed treatment with Adbry (tralokinumab-ldrm) plus topical corticosteroids (TCS) as needed demonstrated improvements in the extent and severity of AD, sleep interference, and quality of life over 32 weeks in adults with Moderate to severe AD.1

Adbry, a high-affinity human monoclonal antibody, was approved by the United States Food and Drug Administration (FDA) in December 2021 for the treatment of adults with moderate to severe AD and is the first and only FDA-approved biologic that specifically binds and inhibits the cytokine interleukin (IL)-13one of the drivers of AD signs and symptoms.2.3

A pre-specified analysis of patients achieving a response at week 16 has been reported elsewhere.4 To reflect clinical practice, this post-hoc analysis pooled all patients treated with Adbry every other week (Q2W) during the initial treatment period, regardless of response at week 16 and dosing regimen (Q2W or every four weeks [Q4W]) received beyond week 16.1 Post-hoc analysis revealed that treatment with Adbry plus TCS, as needed, improved the extent and severity of AD, as well as sleep interference and quality of life measures over 32 weeks.1

Specifically, results at week 32 (n=252) demonstrated that patients treated with Adbry:1

  • Improvement in the extent and severity of AD, with 70.2% achieving a 75% or greater improvement in the Eczema Area and Severity Index (EASI-75) score and 50.4% reaching EASI-90.

  • Achieved a 70.8% improvement in the weekly mean Numerical Rating Scale (NRS) of Eczema-Related Sleep Interference from baseline.

  • Achieved a 66.8% improvement in Dermatologic Quality of Life Index (DLQI) from baseline.

At week 16 (n=247), 89.9% of patients starting treatment with Adbry achieved clinically meaningful improvements in at least one of three disease measures, including extent and severity of AD (≥50% improvement in EASI score [EASI-50]), pruritus (improvement ≥ 3 points in the weekly average of the NRS of the worst daily pruritus) or quality of life (reduction ≥ 4 points in the DLQI score).1 Additionally, 75.3% of patients achieved EASI-50 as well as clinically meaningful improvements in pruritus or quality of life.1

Safety results have been previously reported for ECZTRA 3. The most common adverse events with Adbry (incidence ≥1% and greater than placebo) were upper respiratory tract infections (predominantly reported as a cold), conjunctivitis, allergic reactions injection site and eosinophilia.1.2

“This latest peer-reviewed publication adds to the body of research to support the efficacy and safety of Adbry,” said Adriana Guana, MD, Vice President, US Medical Affairs, LEO Pharma Inc. “The results provide additional context on the benefits of Adbry, including the impact on metrics that are important to clinicians and patients and, ultimately, can help inform clinical decisions.

About the ECZTRA 3 trial

ECZTRA 3 (ECZema TRAlokinumab trial No. 3) was a multinational, double-blind, randomized, placebo-controlled, 32-week study that included 380 adult patients, to evaluate the efficacy and safety of tralokinumab -ldrm (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 is a chronic inflammatory skin disease characterized by intense itching and eczematous lesions.5 Atopic dermatitis is the result of skin barrier dysfunction and immune dysregulation, resulting in chronic inflammation.6 Type 2 cytokines, including IL-13, play an important role in the pathophysiology of atopic dermatitis.seven

About Adbry (tralokinumab-ldrm)

Adbry (tralokinumab-ldrm) is a high-affinity human monoclonal antibody developed to bind to and inhibit the cytokine interleukin (IL)-13, which plays a role in the immune and inflammatory processes underlying the signs and symptoms of atopic dermatitis . Adbry specifically binds to the cytokine IL-13, thereby inhibiting interaction with the α1 and α2 subunits of IL-13 receptors (IL-13Rα1 and IL-13Rα2).3.7


What is ADBRY?

  • ADBRY (tralokinumab-ldrm) injection is a prescription medicine used to treat adults with moderate to severe atopic dermatitis (eczema) that is not well controlled by prescription treatments used on the skin (topicals) or cannot use topical treatments. ADBRY can be used with or without topical corticosteroids.

  • It is not known if ADBRY is safe and effective in children.

Do not use ADBRY if you are allergic to tralokinumab or any of its ingredients.
