A Phase 1/2 Study of E6005 in Pediatric Subjects With Atopic Dermatitis

May 29, 2025 updated by: Organon and Co
This is a multicenter, double-blind, vehicle-control study of 0.05% and 0.2% E6005 ointment. Pediatric subjects with atopic dermatitis (AD) will be grouped into two; an elder group (childhood - adolescent: 7 to 15 years of age) and a younger group (children: 2 to 6 years of age) according to the sequential cohorts by confirming the safety.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 15 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria

  1. Pediatric out-patients diagnosed with AD aged 2 to 15 years at the time of written informed consent. Diagnosis for AD should be made in accordance with the "Guidelines for Management of Atopic Dermatitis" by the Japanese Dermatological Association.
  2. Mild to moderate clinical symptoms appearing at baseline in areas where the application of study drug is possible, except the skin of face/head and non-dermal areas such as mucosa
  3. Evaluable skin lesions appearing at baseline. "Evaluable skin lesion" means rash area of 25 to 100 cm2 in the trunk or extremities, in which at least one of dermal symptoms (erythema, exudate/eschar, excoriation or lichenification) must be moderate in severity.
  4. Continuous use of an appropriate moisturizer for at least 14 days before baseline
  5. Females of child-bearing potential must be negative for pregnancy test at baseline and are able to practice effective contraception during the study period including the follow-up period
  6. Virile males and females of childbearing potential, who and whose partners consented to practice contraception throughout the study period after receiving an explanation using the informed consent form and the separately-prepared assent form
  7. Patients whose legally acceptable representatives (caregivers) are able to consent in writing to participate in the study and who are able to adhere to the protocol requirements. For patients aged 12 years or older at the time of informed consent, written consent should be obtained from the patients as well as their legally acceptable representatives (caregivers). Also for patients aged below 12 years, written informed consent should be obtained whenever possible.

Exclusion Criteria

  1. Use of biological products which may affect the pathological evaluation of AD within 6 months before the start of study treatment
  2. Concurrent or recent use of certain topical or systemic medications or phototherapy without a sufficient washout period, except hydrocortisone butyrate preparations used in areas which are unsuitable for application of study drug at the discretion of the investigator
  3. Currently has Kaposi's varicelliform eruption, scabies, molluscum contagiosum, impetigo contagious, psoriasis, connective tissue disorder, or Netherton's syndrome, etc, which may affect the pathological evaluation of AD
  4. Any past history or present illness of serious allergy such as anaphylactic shock, anaphylactic reaction and anaphylactoid reaction, or any past history or present illness of drug allergic reaction or hypersensitivity
  5. Has active infection that requires oral or intravenous administration of antibiotics, antifungal or antivirus agents at baseline
  6. Currently has an advanced disease or highly abnormal laboratory test result that may affect the safety of subject or the implementation of the study
  7. Difficulty in venous access for blood collection
  8. Any past history or present illness of malignant tumor, lymphoma, leukemia or lymphoproliferative disorder, except non-melanoma skin carcinoma (e.g., squamous cell carcinoma and basal cell carcinoma) which was completely removed and has not recurred or metastasized for at least 5 years
  9. Scheduled for surgery during the study
  10. Concurrently enrolled in another clinical study or used any investigational drug or device within 30 days before the date of informed consent
  11. Ineligible for participating in the study for other reasons, in the judgment of the investigator or subinvestigator

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics of E6005
Time Frame: Up to 21 Days
The whole blood concentrations of E6005 and major metabolite will be evaluated at each visit
Up to 21 Days
Number of participants with adverse events as a measure of the safety and tolerability of E6005
Time Frame: Up to 21 Days
The safety variables include adverse events, clinical laboratory parameters, vital signs and ECG results.
Up to 21 Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in severity score of targeted eczema
Time Frame: Baseline and Day 15
For targeted eczema defined at baseline, intensity of 4 symptoms (erythema, infiltration/papulation, excoriation, and lichenification) will be assessed using a 5-grade scoring method (0: clear, 1: almost clear, 2: mild, 3: moderate, 4: severe) (maximal score: 16).
Baseline and Day 15
Change from Baseline in severity assessment by Investigator's Global Assessment (IGA) for targeted eczema and whole application sites
Time Frame: Baseline and Day 15
Severity of AD dermal symptoms in targeted eczema and whole application sites wil be assessed based on a 6-grade scoring method (0: clear, 1: almost clear, 2: mild, 3: moderate, 4: severe, 5: most severe).
Baseline and Day 15
Change from Baseline in intensity of pruritus
Time Frame: Baseline and Day 15
1) Interview-based pruritus scores: Subjects or caregivers (who must not be changed throughout the study) will assess the intensity of pruritus day and night within 3 days before the visit. 2) Investigator-assessed pruritus: The investigator will assess pruritus conditions by grading into 5 levels (0: clear, 1: almost clear, 2: mild, 3: moderate, 4: severe) based on the comprehensive judgments of interview and scratching behaviors.
Baseline and Day 15
