Galderma @ EADV 2023: Phase III Trials Demonstrate Nemolizumab’s Efficacy and Rapid Onset of Action in Atopic Dermatitis and Prurigo Nodular

ZUG, Switzerland - Wednesday, 11. October 2023

 

  • The phase III ARCADIA 1 and 2 trials met their co-primary and all key secondary endpoints, demonstrating the efficacy of nemolizumab in patients with moderate to severe atopic dermatitis, and early and sustained improvement in itch as early as week 1.1
  • Results from the phase III OLYMPIA 1 trial in patients with prurigo nodularis also met both primary endpoints and all key secondary endpoints, confirming nemolizumab’s rapid onset of action on itch.2
  • 81% of adults with atopic dermatitis describe itch as among their three most problematic symptoms, while many patients with prurigo nodularis also report itch as the most burdensome symptom.3,4
  • Nemolizumab is a first-in-class investigational monoclonal antibody that blocks the signaling of IL-31, a neuroimmune cytokine responsible for driving multiple disease mechanisms in atopic dermatitis and prurigo nodularis.

 

(BUSINESS WIRE) -- Galderma announced positive data from three pivotal phase III trials in atopic dermatitis and prurigo nodularis – ARCADIA 1 and 2 and OLYMPIA 1, respectively. The late-breaking data were presented today at the 2023 European Academy of Dermatology and Venereology (EADV) congress in Berlin. The ARCADIA 1 and 2 trials met their co-primary and all key secondary endpoints, demonstrating that nemolizumab significantly reduced skin lesions and itch in patients with atopic dermatitis, with clinically meaningful results for itch improvement as early as week 1.1

“While atopic dermatitis and prurigo nodularis are distinct diseases, their commonality lies in the severe, persistent itch, which leads to poor quality sleep and negatively impacts mental health. These important results highlight nemolizumab’s potential to be an effective and convenient treatment for the millions of people globally who live with these conditions.”

Results from the ARCADIA 1 and 2 trials showed that nemolizumab significantly improved skin lesions and itch in adolescent and adult patients with moderate to severe atopic dermatitis, compared to placebo (both administered with background topical corticosteroid therapy or topical calcineurin inhibitors). In both trials, adolescent and adult patients treated with nemolizumab showed clinically and statistically significant improvements in co-primary endpoints, compared to placebo after 16 weeks of treatment. Results across both trials showed:1

    35.6% and 37.7% of nemolizumab-treated patients in ARCADIA 1 and 2, respectively, reached clearance or almost-clearance of skin lesions when assessed using the investigator’s global assessment (IGA) score, compared to 24.6% and 26.0% in the placebo group (p<0.0006, p=0.001).

    43.5 percent and 42.1% of nemolizumab-treated patients in ARCADIA 1 and 2, respectively, achieved a 75% reduction in the Eczema Area and Severity Index (EASI), compared to 29.0% and 30.2% in the placebo group (p<0.0001, p=0.0011).

The trials also met all key secondary endpoints, with 48.6% and 48.1% of nemolizumab-treated patients achieving an at least four-point reduction in itch in ARCADIA 1 and 2, respectively, as measured by the peak-pruritus numerical rating scale (PP-NRS) score, compared to 20.5% and 20.6% in the placebo group (p<0.0001), within 16 weeks of treatment. Statistically significant results at week 16 and earlier time points also show nemolizumab’s rapid onset of action on itch and sleep disturbance. Nemolizumab was well tolerated, and its safety profile was consistent between the ARCADIA 1 and 2 studies.1

Data from the phase III OLYMPIA 1 trial bolster evidence for nemolizumab’s rapid onset of action on itch and reduction of skin lesions in patients with prurigo nodularis

In the phase III OLYMPIA 1 trial, nemolizumab as a monotherapy significantly improved itch and skin lesions in adult patients with moderate to severe prurigo nodularis, compared to placebo. Patients treated with nemolizumab monotherapy (without background topical corticosteroids or topical calcineurin inhibitors) showed clinically and statistically significant improvements in both primary endpoints, compared to placebo after 16 weeks of treatment, providing independent confirmation of results from the phase III OLYMPIA 2 trial:2

    58.4% of nemolizumab-treated patients achieved an at least four-point reduction in itch, as measured by the PP-NRS score, compared to 16.7% in the placebo group (p<0.0001).

    26.3% of nemolizumab-treated patients reached clearance or almost-clearance of skin lesions, when assessed using the IGA score, compared to 7.3% in the placebo group (p<0.0001).

The trial also met all key secondary endpoints confirming rapid onset of action on itch as early as week 4 (41.1% compared to 6.3% in the placebo group; p<0.0001), and improvements in itch and skin lesions were observed up to week 24. Nemolizumab was well tolerated, and its safety profile was consistent with OLYMPIA 2 trial results.2

“Through targeting the neuroimmune cytokine IL-31, these phase III data demonstrate that nemolizumab significantly and quickly improves three of the most burdensome symptoms of these conditions: itch, skin lesions, and sleep disturbance.”

Nemolizumab is an investigational monoclonal antibody specifically designed to target the IL-31 receptor and inhibit IL-31 signaling. IL-31 plays a key role in multiple disease mechanisms in both atopic dermatitis and prurigo nodularis.5-10 This includes directly addressing the source of itch, which causes sleep disturbance and negatively impacts quality of life outcomes.3,4,7-13 Results from the ARCADIA and OLYMPIA phase III trials will be submitted to selected health authorities around the world. Nemolizumab was granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) in December 2019 for the treatment of itch associated with prurigo nodularis.

About atopic dermatitis
Atopic dermatitis is a common and chronic form of eczema characterized by persistent, disruptive itch (pruritus), inflammatory skin lesions, and frequent skin infections, affecting 230 million people worldwide.5,14 Reported prevalence of atopic dermatitis varies greatly, ranging from 1% to 25% of the population depending on the geography and age range.4,12,13

About prurigo nodularis
Prurigo nodularis is a debilitating chronic skin condition characterized by thick skin nodules covering large body areas and associated with intense itch (pruritus).6,15,16 Prurigo nodularis affects an estimated 72 out of every 100,000 adults aged 18 to 64 in the United States. It is more common in middle-aged women and, disproportionately, people of African descent.6,17

About nemolizumab
Nemolizumab is in clinical development for the treatment of atopic dermatitis and prurigo nodularis in many countries around the world. It 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 is in development for prurigo nodularis.

About the ARCADIA clinical trial program
The ARCADIA program included two identical, pivotal phase III clinical trials which enrolled more than 1,500 patients – ARCADIA 1 and ARCADIA 2. The trials evaluated the efficacy and safety of nemolizumab administered subcutaneously every four weeks, compared to placebo, in adolescent and adult patients with moderate to severe atopic dermatitis. Patients were evaluated after a 16-week initial treatment period. Clinical responders continued to a maintenance treatment period for up to an additional 32 weeks thereafter. Clinical non-responder patients at week 16 could enroll into a long-term extension study.

About the OLYMPIA 1 trial
OLYMPIA 1 was a randomized, double-blind, placebo-controlled phase III clinical trial designed to assess the efficacy and safety of nemolizumab monotherapy compared with placebo in patients aged at least 18 with prurigo nodularis after a 16-week treatment period. The trial also assessed the pharmacokinetics and immunogenicity of nemolizumab compared to placebo. OLYMPIA 1 included 286 patients with moderate to severe prurigo nodularis.
