  • LEO Pharma is seeking to expand the availability of Anzupgo® (delgocitinib) cream to China, as the company announces the submission of a New Drug Application (NDA) to the National Medical Products Administration (NMPA), which has been accepted for review for adult patients with moderate to severe chronic hand eczema.
  • The NDA is supported by results from DELTA China, a phase 3 trial with Anzupgo in Chinese adults with moderate to severe chronic hand eczema (CHE)1 along with the full clinical program of delgocitinib, which includes data from DELTA 1,2 and 3, DELTA Force and DELTA Teen.2-7
  • The Anzupgo NDA submission demonstrates LEO Pharma's commitment to providing additional treatment options for patients living with skin diseases in China.

BALLERUP, Denmark, October 16, 2025 -- LEO Pharma A/S, a global leader in medical dermatology, has today announced submission of the New Drug Application (NDA) to the National Medical Products Administration (NMPA) in China for Anzupgo® (delgocitinib) cream to treat adult Chinese patients living with moderate to severe chronic hand eczema (CHE), for whom topical corticosteroids are inadequate or inappropriate. The NDA has been accepted for review by NMPA.

“With this submission of our NDA for Anzupgo, LEO Pharma is demonstrating our position as a global leader in medical dermatology. This submission underscores Anzupgo’s position as a truly global brand, and we are now taking the next step in hopefully bringing this to Chinese patients” said Frederik Kier, Executive Vice President, International Operations. “China is a vital market for LEO Pharma, and we are proud to continuously invest in supporting skin health in Mainland China. Backed by our global expertise and commitment to innovation, we are excited to drive forward new innovative potential treatment options to provide support to those in China that need it most.”

The submission of this application marks an important milestone in potentially expanding treatment options for adult patients living with CHE in China. If approved, Anzupgo will aim to address a significant unmet medical need among adult patients with CHE, a disease that can have a considerable impact on both quality of life and everyday functioning.8,9,10 There are currently no approved treatment options specifically indicated for moderate to severe CHE in China.

“LEO Pharma strives to enhance patient care and elevate quality of life for those living with complex skin diseases like chronic hand eczema,” said Byron Yin, General Manager for LEO Pharma, China. “Today’s submission is a crucial step towards offering a much-needed new treatment option in our region, in addition to the existing portfolio offering from LEO Pharma China.”

The NDA submission is supported by results from DELTA China, a phase 3 trial with Anzupgo® (delgocitinib) 20mg/g cream, a topical pan-Janus kinase (JAK) inhibitor, for the potential treatment of Chinese adult patients with moderate to severe CHE for whom topical corticosteroids are inadequate or inappropriate.1 

Upon completion of the double-blind treatment period, the trial met its primary endpoint with a statistically significant improvement in CHE severity after 16 weeks of treatment with Anzupgo compared to cream vehicle.1,11

The phase 3 trial consists of a 16-week randomized, double-blind, vehicle-controlled treatment period, followed by an open-label treatment period of 36 weeks.1 A total of 362 subjects were recruited and randomized in a 2:1 ratio to receive either Anzupgo or cream vehicle.1 The open-label treatment period of the DELTA China trial running from Week 16 to Week 52 and is still ongoing.1 The results from this stage of the trial will be released at a later date.

Furthermore, the submission is also backed by the full clinical program of delgocitinib, which includes data from DELTA 1,2 and 3, DELTA Force and DELTA Teen. 2-7

Following the Anzupgo filing acceptance by the Centre for Drug Evaluation (CDE), the full evaluation of the NDA has started. The regulatory review process is expected to conclude in 2027.

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.12,13 CHE is one of the most common skin diseases of the hands with a global prevalence rate of approximately 4.7%.14,15 In a substantial number of patients, HE can develop into a chronic disease.14 CHE is a fluctuating disease characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists.16

CHE has been shown to cause psychological and functional burdens that impact patient quality of life,8,9 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.10 Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE.17

About Anzupgo® (delgocitinib) Cream

Anzupgo cream is a topical pan-Janus kinase (JAK) inhibitor for the treatment of moderate to severe CHE in adults. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE.18

Anzupgo is approved in the European Union, United Kingdom, Switzerland, Canada, Australia, South Korea, and the United Arab Emirates for the treatment of moderate to severe Chronic Hand Eczema (CHE) in adults for whom topical corticosteroids are inadequate or inappropriate. Anzupgo cream is also under investigation in other markets.

Anzupgo® (delgocitinib) cream is also FDA approved in the U.S. for moderate to severe chronic hand eczema (CHE) in adults who have had an inadequate response to, or for whom topical corticosteroids are not advisable. Use of Anzupgo in combination with other JAK inhibitors or potent immunosuppressants is not recommended.19

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 for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights.

About the DELTA China Trial

DELTA China is a phase 3 trial to evaluate efficacy, safety, and pharmacokinetics (PK) (only adults) of

twice-daily applications of Anzupgo in Chinese adults and adolescents (aged 12 and above) with moderate to severe CHE.1

The primary endpoint of the DELTA China trial was the Investigator’s Global Assessment for CHE 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.1

LEO Pharma presents new data on delgocitinib cream at EADV 2026 highlighting real-world outcomes in adults and new adolescent data in Chronic Hand Eczema (CHE)1.10.2026 12:00:00 CEST | Pressemeddelelse

Interim results from the German REACHED study provide the first real-world evidence on the effectiveness of delgocitinib cream in adults with moderate to severe Chronic Hand Eczema (CHE), with 28.6% of patients assessed as clear or almost clear after eight weeks of treatment, from none at baseline.1 New post hoc analyses from the phase 3 DELTA TEEN trial show greater reductions in daily HESD itch and pain scores with delgocitinib cream than with cream vehicle in adolescents aged 12-17 with moderate to severe CHE.2 In an oral presentation, new post hoc analyses from DELTA TEEN show that a higher proportion of adolescents reported no impact on quality of life at Week 16 with delgocitinib cream than with cream vehicle (27.0% vs 0%)3

LEO Pharma presents new tralokinumab data at EADV 2026 highlighting real-world outcomes and quality of life in adults and adolescents with atopic dermatitis (AD) involving high-burden areas1.10.2026 10:30:00 CEST | Pressemeddelelse

New findings from a subgroup analysis of the 12-month TRACE study show that more than 70% of adults whose Atopic Dermatitis (AD) affected multiple high-burden areas – such as the head and neck, hands and feet, or genitals – had reduced involvement of those areas after 12 months of treatment with tralokinumab.1 New pre-specified and post hoc analyses from the phase 3 ADHAND trial show significantly greater improvements in quality of life, daily function and sleep at Week 16 with tralokinumab monotherapy than with placebo in adults with AD and moderate-to-severe hand involvement, with the two treatment groups separating within two weeks.2,3 In a post hoc analysis, adolescents aged 12-17 years treated across the phase 3 ECZTRA 6 trial and its ECZTEND extension, response rates remained high and stable through most of the extension period, and no new safety concerns were identified.5

LEO Pharma receives positive CHMP opinion recommending Anzupgo® (delgocitinib) cream for adolescents with moderate to severe chronic hand eczema in the EU18.9.2026 10:00:00 CEST | Pressemeddelelse

The Committee for Medicinal Products for Human Use (CHMP) has recommended expanding the use of Anzupgo® (delgocitinib) cream to adolescents aged 12 to 17 years with moderate to severe chronic hand eczema for whom topical corticosteroids are inadequate or inappropriate. If approved by the European Commission, Anzupgo® would become the first therapy in the EU specifically approved for adolescents with moderate to severe chronic hand eczema, a patient population for whom there are currently no specifically approved treatment options. The positive CHMP opinion is supported by results from DELTA TEEN, a phase 3 trial investigating the efficacy and safety of Anzupgo® in adolescents with moderate to severe chronic hand eczema.1
