Evaluation of the Inhibitory Effects of Topical Ivermectin on Markers of Rosacea Specific Inflammation.

October 1, 2021 updated by: Tissa Hata, MD, University of California, San Diego

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.

Study Overview

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Subject is male or non-pregnant female, 18 - 70 years of age.
  • Subjects willing and able to give informed consent.
  • Subjects willing and able to comply with the requirements of the study.
  • Subject has the clinical diagnosis of rosacea with at least one inflammatory papule and at least mild erythema.
  • Subject has been on a stable dose for greater than 3 months of medications for treatment of concurrent medical condition (including oral contraceptive pills, vasodilators, adrenergic blocking agents) OR the investigator has determined that the medications are unlikely to affect the patient's rosacea and/or treatment during the study
  • Subject is in general good health in the opinion of the investigator.
  • Subject has normal baseline labs or in the opinion of the investigator are values are not clinically significant and would not inhibit the ability to monitor the patient for both safety and efficacy throughout the study.

Exclusion Criteria:

  • Subject has a diagnosis of Steroid Rosacea or Pyoderma Faciale (rosacea fulminans).
  • Subject has used facial topical therapies (OTC drug products or prescription products) for any reason within the prior 28 days
  • Subject has used systemic corticosteroid or systemic antibiotics (especially doxycycline, minocycline, tetracycline, metronidazole) within the prior 28 days.
  • Subject has had laser or light-based treatment for rosacea within the prior 3 months.
  • Subject has had systemic retinoids and retinoid derivatives over the past 6 months
  • Subject has a known hypersensitivity or allergy to topical ivermectin or components of the vehicle.
  • Subject is pregnant or lactating or planning a pregnancy during the duration of the study
  • Subject has been treated with another investigational device or drug within 28 days prior to study enrollment or intends to participate in a clinical trial concurrent with this study
  • Subject has clinically significant findings, medical history or conditions (other than rosacea), which in the opinion of the Investigator may compromise the study, treatment protocol, or safety of the patient or treatment allocation

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
Relative Trypsin-like Enzyme Activity
Time Frame: 12 weeks
Activity was quantified using a protease activity assay involving aprotinin, a known selective inhibitor of trypsin-related enzyme activity
12 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
