Primary outcome
Adverse event
Time frame: Up to post study visit (Day 40)
For all adverse events collected during the study, the investigator will evaluate serious adverse events, severity, or drug relationship.
Physical examination
Time frame: Up to post study visit (Day 40)
Physical examination results will be classified as normal, not clinically significant, or clinically significant upon a judgment of the investigator after single/multiple dosing of topical IN-A002 Ointment.
Clinical Laboratory Test
Time frame: Up to post study visit (Day 40)
Clinical laboratory test, the results will be classified as normal, not clinically significant, or clinically significant upon judgment of the investigator after single/multiple dosing of topical IN-A002 Ointment.
Topical Reaction Assessment
Time frame: Predose(0h) at Day 1, Day 8, Day 15, and Day 22, Post-dose(0.5h) at Day 1, Day 8, Day 15, and Day 22, Day 28, Day 29(0h, 0.5h), PSV

Questions about this trial
What is this clinical trial studying?
A Phase 1 study of Mild to Moderate Atopic Dermatitis, run by HK inno.N Corporation at 1 site in South Korea.
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 14 inclusion and 67 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 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Adverse event (time frame: Up to post study visit (Day 40)). The study lists 9 primary outcomes in all. 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 14 Sep 2026.
