Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Currently, there is no known cure for rosacea. The most effective treatment is systemic antibiotics, particularly of the tetracycline family. Topical treatments include metronidazole, antibacterials such as erythromycin and clindamycin, sulfacetamide and benzoyl peroxide. Isotretinoin (Accutane) is also used.

Study Type

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Subjects 18 years of age and older.
  2. Clinical diagnosis of papulopustular facial rosacea.
  3. A minimum of 4 but not more than 50 facial inflammatory lesions (papules plus pustules).
  4. Willing and able to understand and sign informed consent.
  5. Able to complete study and comply with study procedures.

Exclusion Criteria:

  1. Acne conglobata, acne fulminans, secondary acne (chloracne, drug-induced acne, etc.), or severe acne requiring systemic treatment.
  2. History or presence of regional enteritis or inflammatory bowel disease (e.g., ulcerative colitis, pseudomembranous colitis, chronic diarrhea, or a history of antibiotic-associated colitis, bloody diarrhea) or similar symptoms.
  3. Use of topical rosacea treatments in the past 2 weeks.
  4. Use of systemic antibiotics in the past 4 weeks.
  5. Use of systemic retinoids within the past 3 months.
  6. Use of laser or light based rosacea treatments within the past 2 months.
  7. Concomitant use of medications that are reported to exacerbate rosacea, such as topical and systemic steroids as these may impact assessments.
  8. Current drug or alcohol abuse.
  9. Other dermatologic conditions that require the use of interfering topical or systemic therapy or that might interfere with study assessments such as, but not limited to, atopic dermatitis, perioral dermatitis or acne vulgaris.
  10. Clinically significant abnormal findings or conditions (other than rosacea), which might, in the opinion of the Investigator, interfere with study evaluations or pose a risk to subject safety during the study.
  11. Subjects who are pregnant or planning a pregnancy.
  12. Use of any investigational therapy within the past 4 weeks.
  13. Known hypersensitivity or previous allergic reaction to clindamycin or retinoids

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
Mean Change in Number of Inflammatory Lesions From Baseline to Week 12
Time Frame: Baseline, week 12
The number of inflammatory lesions (papules and pustules) on the face were counted by a dermatologist at baseline and week 12 for each participant. Change in the number of inflammatory lesions is defined as week 12 values minus the baseline values of the participant. Last observation carried forward (LOCF) method was used for missing values.
Baseline, week 12
