Study summary

Atopic dermatitis is a chronic inflammatory skin disease that is commonly associated with itching, sleep disturbance, and impaired quality of life. Melatonin may have beneficial effects on sleep, inflammation, and oxidative stress.

This randomized controlled trial will evaluate the effectiveness of oral melatonin as an adjunct to standard treatment in adults with atopic dermatitis. A total of 130 participants will be randomly assigned in a 1:1 ratio to receive either standard treatment according to the Vietnamese Ministry of Health 2023 guideline or standard treatment plus oral melatonin 6 mg once daily for 4 weeks.

Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index, and sleep quality will be evaluated using the Pittsburgh Sleep Quality Index (PSQI). Serum superoxide dismutase and melatonin concentrations will also be measured to assess changes related to oxidative stress and melatonin status. Participants will be evaluated at baseline and during the 4-week treatment period.

Read the detailed description

Atopic dermatitis is a chronic, relapsing inflammatory skin disease characterized by pruritus and inflammatory skin lesions. Sleep disturbance is common in patients with atopic dermatitis and may be related to both disease activity and alterations in circadian and oxidative stress pathways.

Melatonin is involved in the regulation of the sleep-wake cycle and also has antioxidant, anti-inflammatory, and immunomodulatory properties. These effects provide a biological rationale for evaluating melatonin as an adjunctive treatment in atopic dermatitis.

In this study, adults diagnosed with atopic dermatitis who meet the eligibility criteria will be randomly allocated to one of two parallel treatment groups. The control group will receive standard treatment for atopic dermatitis according to the Vietnamese Ministry of Health 2023 guideline. The experimental group will receive the same standard treatment plus oral melatonin 6 mg once daily, taken approximately 60 minutes before bedtime.

Participants will be followed for 4 weeks. Clinical disease severity will be assessed using the SCORAD index at baseline, Week 2, and Week 4. Sleep quality will be evaluated using the PSQI at baseline and Week 4. Serum superoxide dismutase and melatonin concentrations will be measured before treatment and after 4 weeks of treatment. Adverse effects occurring during treatment will also be recorded.

The study will compare changes in clinical severity, sleep quality, and biological markers between the two treatment groups to determine whether adjunctive oral melatonin provides additional benefit over standard treatment alone.

    • Chronic or chronically relapsing dermatitis.
    • Personal or family history of atopic disease, including asthma, allergic rhinitis, or atopic dermatitis.
  • Minor criteria may include xerosis, ichthyosis vulgaris, immediate skin test reactivity, elevated serum IgE, early age of onset, tendency toward skin infections, nonspecific hand or foot dermatitis, nipple eczema, cheilitis, recurrent conjunctivitis, Dennie-Morgan infraorbital fold, keratoconus, anterior subcapsular cataract, periorbital darkening, facial erythema or pallor, pityriasis alba, anterior neck folds, itching with sweating, intolerance to wool or lipid solvents, perifollicular hyperkeratosis, food allergy, disease course influenced by environmental or psychological factors, or white dermographism.
  • Willing and able to provide .

Exclusion criteria

Exclusion Criteria:

  • Acute infectious disease.
  • Another skin disorder involving the same area as the atopic dermatitis lesions or the venipuncture site.
  • Serious systemic disease.
  • Known allergy or to melatonin.
  • Immunodeficiency, including /AIDS, diabetes mellitus, or previous use of drugs.
  • Severe coagulation disorder or use of high-dose anticoagulant therapy.
  • Use of glutathione, vitamin C, vitamin E, zinc, iron, or folic acid within 3 months before or during data collection.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Change in SCORAD Score From Baseline to Week 4

    Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index. The total SCORAD score ranges from 0 to 103, with higher scores indicating greater disease severity. The change in total SCORAD score from baseline to Week 4 will be compared between the standard treatment group and the standard treatment plus melatonin group.

    Time frame: Baseline to Week 4

Secondary outcomes

  1. Change in SCORAD Score From Baseline to Week 2

    Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index. The change in total SCORAD score from baseline to Week 2 will be compared between the standard treatment group and the standard treatment plus melatonin group. Higher SCORAD scores indicate greater disease severity.

    Time frame: Baseline to Week 2

  2. Change in Pittsburgh Sleep Quality Index Score From Baseline to Week 4

    Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). The total score ranges from 0 to 21, with higher scores indicating poorer sleep quality. Change from baseline to Week 4 will be compared between treatment groups.

    Time frame: Baseline to Week 4

  3. Change in Serum Superoxide Dismutase Concentration From Baseline to Week 4

    Serum superoxide dismutase concentration will be measured before treatment and after 4 weeks to evaluate changes in oxidative stress-related antioxidant status.

    Time frame: Baseline to Week 4

  4. Change in Serum Melatonin Concentration From Baseline to Week 4

    Serum melatonin concentration will be measured before treatment and after 4 weeks. Changes from baseline will be evaluated and compared between treatment groups.

    Time frame: Baseline to Week 4

  5. Clinical Treatment Response According to SCORAD

    Treatment response will be categorized according to the study protocol as good, moderate, or poor/no response based on improvement in clinical manifestations, change in total SCORAD score, and change in disease severity category.

    Time frame: Week 2 and Week 4

  6. Adverse Events During Treatment

    The number and proportion of participants experiencing treatment-related adverse effects, including adverse effects associated with melatonin and concomitant treatments, will be recorded.

    Time frame: Baseline through Week 4

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Oct 2026; primary completion for Oct 2027, 12 months later.

Of 113 non-industry interventional studies with no phase under Dermatitis, Atopic, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 43. This study's planned 12 months is below that.

Counting every sponsor, half of 182 studies reached it within 15 months; a quarter within 6 and three quarters within 34.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
