LEO Pharma Receives Positive CHMP Opinion of Anzupgo (delgocitinib cream) for the Treatment of Adults with Moderate to Severe Chronic Hand Eczema (CHE)

BALLERUP, Denmark, July 26, 2024 -- LEO Pharma A/S, a global leader in medical dermatology, today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion that recommends the approval of Anzupgo® (delgocitinib cream) for the treatment of adult patients with moderate to severe chronic hand eczema (CHE), for whom topical corticosteroids are inadequate or inappropriate.

Delgocitinib cream is an investigational topical pan-JAK inhibitor for CHE. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE.5 Currently, there are no topical treatments specifically approved for adults with moderate to severe CHE for whom topical corticosteroids are inadequate or inappropriate.

CHE is a heterogeneous, fluctuating, inflammatory skin disease with key symptoms of itch and pain. Its pathophysiology is characterized by skin barrier dysfunction, skin inflammation, and skin microbiome alterations.6 The condition has been proven to have a high psychological, social, and occupational burden.7,8,9

It is well known that CHE is challenging to live with and manage, potentially impacting personal relationships and careers,” said Christophe Bourdon, Chief Executive Officer, LEO Pharma. “Despite the considerable burden of the condition, treatments options approved for CHE have been limited. As an organization, we are dedicated to helping advance the standard of care for the benefit of people with skin conditions, and today we are one step closer to addressing the unmet need that may be faced by those living with CHE.

The positive CHMP opinion for delgocitinib cream is based on results from the phase 3 program, which includes the DELTA 1 and DELTA 2 clinical trials that evaluated the safety and efficacy of delgocitinib cream compared to cream vehicle.1,2,3 Both trials met their primary and all secondary endpoints.10,11 Subjects who completed the 16-week DELTA 1 or DELTA 2 trials were immediately offered to enroll in the 36-week DELTA 3 open-label extension trial.4 Results demonstrated a long-term safety profile consistent with previous trial results.

The practical and highly visible location of CHE brings a considerable burden,” said Kreesten Meldgaard Madsen, Chief Development Officer, LEO Pharma. “Our hands are integral to every aspect of our day to day lives, so avoiding physical triggers can be challenging for people living with CHE. At the same time, the highly visible area of this condition can have a negative impact psychologically and emotionally. I am incredibly proud of this milestone and we will now continue our work to support those living with CHE.

The CHMP’s positive opinion will be reviewed by the European Commission (EC) and, pending the final decision, authorization of delgocitinib cream will be valid in all EU member states, Iceland, Norway, and Liechtenstein. Regulatory filings in other markets are underway.

About the DELTA 1, 2 and 3 Trials

The primary objective for the randomized, double-blind, vehicle-controlled, multi-center phase 3 clinical trials (DELTA 1 and DELTA 2) was to evaluate the efficacy of twice-daily applications of delgocitinib cream compared with cream vehicle in the treatment of adults with moderate to severe CHE.

The primary endpoint of the trials was the Investigator’s Global Assessment for chronic hand eczema treatment success (IGA-CHE TS) at Week 16. Treatment success was defined as an IGA-CHE score of 0 (clear) or 1 (almost clear) with at least a two-step improvement from baseline. Additional IGA-CHE scores included 2 (mild), 3 (moderate), and 4 (severe).

Key secondary endpoints at Week 16 included reduction of itch and pain scores of ≥4 points measured by the Hand Eczema Symptom Diary (HESD) from baseline to Week 16, as well as at least 75% improvement from baseline and at least 90% improvement from baseline on the Hand Eczema Severity Index (HECSI) at Week 16. The number of treatment-emergent adverse events from baseline to Week 16 defined the key safety endpoint of the trials.

Subjects who completed 16 weeks of treatment with delgocitinib cream or cream vehicle twice daily in trials DELTA 1 or DELTA 2 were offered to roll-over to the 36-week DELTA 3 Open-label, Multi-site Extension trial. The purpose of this extension trial was to evaluate the long-term safety of delgocitinib.

About Chronic Hand Eczema

Chronic hand eczema (CHE) is defined as hand eczema (HE) that lasts for more than three months or relapses twice or more within a year. HE is the most common skin disorder of the hands with a one-year prevalence rate of approximately 9%. In a substantial number of patients, HE can develop into a chronic condition.15 CHE is a fluctuating disorder characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists.

CHE has been shown to cause psychological and functional burdens that impact patient quality of life, with approximately 70% of individuals who live with severe CHE admitting to problems in performing everyday activities, and suffering disruption in their daily life due to the condition. Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE.

About Anzupgo (delgocitinib cream)

Anzupgo® (delgocitinib cream) is an investigational topical pan-Janus kinase (JAK) inhibitor for moderate to severe CHE. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE.5 The pathophysiology is characterized by skin barrier dysfunction, inflammation of the skin, and alterations of the skin microbiome.6 LEO Pharma is currently developing delgocitinib cream formulation for the treatment of moderate to severe chronic hand eczema (CHE) in adults, which is currently not approved by any health authority. In 2014, LEO Pharma A/S and Japan Tobacco Inc. (JT) entered into a license agreement in which LEO Pharma gained exclusive rights to develop and commercialize delgocitinib cream for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights.
