Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Age 18 years or above at screening for adult participants and age 12-17 years at screening and baseline for adolescent participants.
  • Diagnosis of CHE, defined as hand eczema that has persisted for more than 3 months or returned twice or more within the last 12 months. Disease severity graded as moderate to severe at screening and baseline according to IGA-CHE (i.e. an IGA-CHE score of 3 or 4).
  • HESD itch score (weekly average) of ≥4 points at baseline. The baseline weekly average will be calculated from daily assessments of itch severity during the 7 days immediately preceding the baseline visit (Day -7 to Day -1). A minimum of 4 itch scores out of the 7 days is required to calculate the baseline average score.
  • Participants who have a documented recent history of inadequate response to treatment with topical corticosteroids (TCS) (at any time within 1 year before the screening visit) or for whom TCS are documented to be otherwise medically inadvisable (e.g. due to important side effects or safety risks).
  • Inadequate response is defined as a history of failure to achieve and maintain a low disease activity state (comparable to an IGACHE score of ≤2) despite treatment with a daily regimen of TCS of class III-IV (potent to very potent), applied for at least 28 days or for the maximum duration recommended by the product prescribing information, whichever is shorter.
  • Important side effects or safety risks are those that outweigh the potential treatment benefits and include intolerance to treatment, hypersensitivity reactions, and significant skin atrophy as assessed by the physician.
  • Participants adherent to standard non-medicated skin care including avoidance of known and relevant irritants and allergens.
  • A woman of childbearing potential (WOCBP) must use an acceptable method of birth control throughout the trial up until the last application of investigational medicinal product (IMP).

Who cannot join

  • Active atopic dermatitis (AD) requiring medical treatment in regions other than the hands and feet.
  • Hyperkeratotic hand eczema in combination with a history of psoriasis on any part of the body.
  • Clinically significant infection (e.g. impetiginized hand eczema) on the hands.
  • Clinically significant infection within 28 days prior to baseline which, in the opinion of the investigator, may compromise the safety of the participant in the trial, interfere with evaluation of the investigational medicinal product (IMP), or reduce the participant's ability to participate in the trial. Clinically significant infections are defined as:
  • A systemic infection.
  • A serious skin infection requiring parenteral (intravenous or intramuscular) antibiotics, antiviral, or antifungal medication.
Show all 39Show fewer
  • History of any known primary immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test at screening, or the participant taking antiretroviral medications as determined by medical history and/or participant's verbal report.
  • History of cancer:
  • Participants who have had basal cell carcinoma, localized squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible provided that the participant is in remission and curative therapy was completed at least 12 months prior to screening.
  • Participants who have had other malignancies are eligible provided that the participant is in remission and curative therapy was completed at least 5 years prior to screening.
  • Any disorder which is not stable and could:
  • Affect the safety of the participant throughout the trial.

About this study

Official title: A Phase 3 Trial to Evaluate Efficacy, Safety, and Pharmacokinetics of Twice-Daily Applications of Delgocitinib Cream 20 mg/g in Chinese Adults and Adolescents (12-17 Years of Age) With Moderate to Severe Chronic Hand Eczema

The primary objective of this study is to evaluate the efficacy of twice-daily applications of delgocitinib cream 20 mg/g compared with cream vehicle in the treatment of participants with moderate to severe chronic hand eczema (CHE).

Read the detailed description

The trial comprises of a 16-week double-blind, treatment period, followed by an open label treatment period of 36 weeks. In the double-blind treatment period two thirds of participants will be randomly assigned to receive delgocitinib and one third will receive placebo/vehicle. In the double-blind treatment period, participants will use delgocitinib twice a day. In the open label period, participants will only use delgocitinib when needed (if their CHE flares up). Some participants will also give blood samples at the start of the trial for pharmacokinetic measurements. Participants will visit the clinic every 4 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Delgocitinib in people with Chronic Hand Eczema, run by LEO Pharma at 37 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 39 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Investigator Global Assessment for Chronic Hand Eczema Score (IGA-CHE TS) at Week 16 (time frame: Week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2025.
