ZUG, Switzerland -- (BUSINESS WIRE) --
Galderma today announced that full results from the phase III ARCADIA 1 and 2 clinical trials in atopic dermatitis were published in The Lancet.1The trials evaluated the efficacy and safety of nemolizumab in combination with background topical corticosteroids (TCS), with or without topical calcineurin inhibitors (TCI), versus placebo in combination with TCS, with or without TCI, in adolescent and adult patients with moderate-to-severe atopic dermatitis.1 Results show that the trials met their co-primary and all key secondary endpoints, showing that nemolizumab significantly improved skin lesions, itch and sleep disturbance by Week 16 when compared to placebo, with significant itch relief observed as early as Week 1.1

“Publication of the phase III ARCADIA program results for the first time in The Lancet reinforces both the robustness of our trial design and the potential of nemolizumab as an effective treatment option for patients living with atopic dermatitis. We are working closely with regulators in the U.S., Europe, and elsewhere to bring nemolizumab to those in need as soon as possible.”

The phase III ARCADIA 1 and 2 trials enrolled 1,728 adolescent and adult patients with moderate-to-severe atopic dermatitis.1 Results demonstrated that patients treated with nemolizumab, administered subcutaneously every four weeks in combination with TCS, with or without TCI, showed statistically significant improvements in both co-primary endpoints, when compared to placebo in combination with TCS, with or without TCI, after 16 weeks of treatment:1
The trials also met all key secondary endpoints confirming rapid responses on itch, and statistically significant improvements in sleep disturbance with nemolizumab in combination with TCS, with or without TCI, when compared to placebo in combination with TCS, with or without TCI:1
The safety profile was consistent between nemolizumab and placebo groups; most treatment-emergent adverse events were non-serious, and of mild-to-moderate severity.1
Nemolizumab is a first-in-class monoclonal antibody specifically designed to target the interleukin-31 (IL-31) receptor alpha and inhibit IL-31 signaling.2 In atopic dermatitis, IL-31 drives itch and is involved in inflammation and skin barrier disruption.3-5

“As a practicing dermatologist, I’m excited about the potential of nemolizumab for atopic dermatitis patients. These phase III data demonstrate that, by blocking the activity of IL-31, nemolizumab could effectively address itch, skin lesions and sleep disturbance. Many patients complain that chronic itch negatively impacts their overall quality of life. Reducing itch within just one week of treatment could significantly ease the burden of disease.”

Based on the results of the ARCADIA 1 and 2 trials, the U.S. Food and Drug Administration accepted for review Galderma’s Biologics License Application for nemolizumab for the treatment of adolescents and adults with moderate-to-severe atopic dermatitis, with a decision expected by the end of the year.6 Galderma is awaiting decisions from several other regulatory authorities on its filing applications for both atopic dermatitis and prurigo nodularis, including the European Medicines Agency, Health Canada, and the Access Consortium.7 Regulatory submissions to other healthcare authorities around the world are ongoing.

About atopic dermatitis
Atopic dermatitis a common, chronic, and flaring inflammatory skin disease, characterized by persistent itch and recurrent skin lesions.4,8,9 It affects more than 230 million people worldwide and is the most common inflammatory skin disease, impacting almost four times more people than psoriasis.4,10 While currently available treatments for atopic dermatitis show some improvements of signs and symptoms, not all patients experience itch relief and clear skin to the same degree, and many do not respond optimally to approved therapies.4,11
About nemolizumab
Nemolizumab is a monoclonal antibody developed by Galderma and is the first therapy designed to specifically inhibit interleukin-31 (IL-31) cytokine signaling.2 IL-31 signaling is known to drive the most burdensome symptom for people with atopic dermatitis and prurigo nodularis – itch.3-5
Nemolizumab is under review for both prurigo nodularis and atopic dermatitis by several regulatory authorities worldwide, including the U.S. Food and Drug Administration, European Medicines Agency and in Australia, Singapore, Switzerland, and the United Kingdom via the Access Consortium, with ongoing submissions in additional countries.6,7
Nemolizumab was initially developed by Chugai Pharmaceutical Co., Ltd., and subsequently licensed to Galderma in 2016 worldwide – except Japan and Taiwan. In Japan, nemolizumab is approved for the treatment of pruritus associated with atopic dermatitis and for prurigo nodularis.12,13
About the ARCADIA clinical trial program1,14,15
The ARCADIA program included two identically designed, pivotal phase III clinical trials, which enrolled more than 1,700 patients – ARCADIA 1 and ARCADIA 2.
These global, randomized, multicenter, double-blind, placebo-controlled phase III clinical trials, evaluated the efficacy and safety of nemolizumab administered subcutaneously every four weeks compared to placebo (both administered with background topical corticosteroids with or without topical calcineurin inhibitors).
The trials were conducted in adolescent and adult patients (12 years and over) with moderate-to-severe atopic dermatitis for an initial treatment phase of 16 weeks. Patients who responded to treatment (defined as patients who achieved an investigator’s global assessment score of clear (0) or almost clear (1), or a 75% or greater improvement in the eczema area and severity index score) were then re-randomized to a maintenance treatment phase for up to 48 weeks.
