About this study
Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Study to Evaluate the Efficacy and Safety of JYP0066 Topical Cream in Adolescents and Adults With Mild-to-Moderate Atopic Dermatitis
This is a Phase 2 research study testing an investigational topical cream called JYP0066 for the treatment of mild-to-moderate atopic dermatitis (eczema) in teenagers (12-17 years old) and adults. The study will check whether JYP0066 cream can reduce eczema signs and symptoms such as redness, itching, dryness, and skin thickening, and whether it is safe and well tolerated.
Participants will be randomly assigned to one of four groups: they will apply either 4%, 3%, or 2% JYP0066 cream, or a matching placebo cream, to eczema-affected skin twice a day for 8 weeks. All creams will look the same. This helps the study compare which concentration works best and how safe each one is.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing JYP0066 4% topical cream, 3% JYP0066 topical cream and 2% JYP0066 topical cream in people with Atopic Dermatitis (AD), run by Guangzhou JOYO Pharma Co., Ltd.
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 9 inclusion and 15 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: opening soon, as of the sponsor's last update on 30 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Percent change from baseline in EASI score at Week 8 (time frame: Baseline to Week 8). 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 30 Sep 2026.
