About this study
Official title: A Single Site Evaluation of the Inhibitory Effects of Topical Ivermectin on Serine Protease Activity and Production of LL-37 Cathelicidin Peptide, Biochemical Markers of Rosacea-specific Inflammation and on the Skin Microbiome in Rosacea.
This study will assess the role of topical Ivermectin 1% cream and its effect on protease and antimicrobial peptide expression and on the skin microbiome (the microorganisms that live on the skin) in rosacea. This is a single-site 16-week open-label study at University of California, San Diego. The investigators will do this by first measuring serine protease activity and cathelicidin and skin microbiome of all subjects. All subjects will receive Ivermectin topical cream and will be instructed on how to apply it daily for 12 weeks. Participants will return for monthly visits during which their clinical symptoms of facial redness and number of facial papules will be scored, and they will have repeat tape stripping and/or skin swabs. At the end of the study, tape strips and skin swabs will be analyzed to determine serine protease activity and skin microbiome of participants at each of their visits and expression of cathelicidin (LL-37) mRNA. The investigators will then look at changes in serine protease activity and LL-37 expression and skin microbiome over time, and they will also determine whether or not these changes correlate with disease severity.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Ivermectin in people with Rosacea, run by University of California, San Diego at 1 site in United States.
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 7 inclusion and 9 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 5 Oct 2021. 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 United States. 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 combined 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.
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?
Yes. Results are posted in the registry (first posted 17 Jul 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Relative Trypsin-like Enzyme Activity (time frame: 12 weeks). 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 5 Oct 2021; AzTrials last refreshed its copy on 8 Nov 2026.
