December 15, 2025 updated by: Tanabe Pharma Corporation

A Confirmatory Study of TAU-284 in Pediatric Patients With Atopic Dermatitis (Ketotifen Fumarate-controlled, Double-blind, Comparative Study)

The objective of this study is to verify the non-inferiority of TAU-284 to ketotifen fumarate dry syrup in the change in the severity of pruritus after the treatment period.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized, double-blind, parallel-group comparative study to demonstrate the noninferiority of TAU-284 to ketotifen fumarate in pediatric patients with atopic dermatitis, as assessed by the primary endpoint of the change from baseline in pruritus score after 2-week treatment with TAU-284 (20 mg/day) or ketotifen fumarate dry syrup (2 g/day); and to investigate the safety, and plasma concentrations of TAU-284.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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
Change From Baseline in Pruritus Score
Time Frame: Baseline and 2 weeks
The pruritus symptoms score were rated on 5-point scale ranging from 0 (none) to 4 (severe).
Baseline and 2 weeks

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 Pruritus Score
Time Frame: Baseline and 1 weeks
The pruritus symptoms score were rated on 5-point scale ranging from 0 (none) to 4 (severe).
