About this study

Official title: A Double-Blind, Placebo-Controlled, Pilot Study to Determine the Safety and Efficacy of Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel For The Treatment of Rosacea Over 12 Weeks

The purpose of this study is to determine whether Clindamycin Phosphate 1.2% And Tretinoin 0.025% Gel are effective and safe in the treatment of papulopustular rosacea.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change in Number of Inflammatory Lesions From Baseline to 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.

    Measured: Baseline, week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Clindamycin Phosphate 1.2% And Tretinoin 0.025% Gel in people with Rosacea, run by Massachusetts General Hospital at 2 sites 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 5 inclusion and 13 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 25 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 15 Jun 2012). 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?

Mean Change in Number of Inflammatory Lesions From Baseline to Week 12 (time frame: Baseline, week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00823901, which also lists 6 linked publications.

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 25 Jun 2012.
