About this study

Official title: An Exploratory, Multicenter, Investigator-blinded, Active-controlled Study to Investigate the Efficacy of Topical Azelaic Acid (AzA)15% Gel Twice Daily or Metronidazole Topical Gel 1% Once Daily, Plus Anti-inflammatory Dose Doxycycline (40mg) Once Daily in Subjects With Moderate Papulopustular Rosacea

Subjects with moderate papulopustular rosacea will be treated either with azelaic acid 15% gel topically plus an anti-inflammatory dose of doxycyline (40mg) daily or with metronidazole 1% gel topically once daily plus an anti-inflammatory dose of doxycycline (40mg) over at total of twelve weeks to determine the rapidity of improvement, and the length of time to reach 25%, 50% and 75% clearing compared to baseline.

Read the detailed description

The change in inflammatory lesion count will be assessed at each post-baseline visit by an analysis of variance model (ANOVA) with factors treatment and center, but not including treatment-by-center interaction.

Investigator's Global Assessment (IGA) of papulopustular rosacea (static score): 0 - Clear (Virtually no rosacea ie, no papules and/or pustules; no or residual erythema; no or mild to moderate degree of telangiectasia may be present); 1 - Minimal (Rare papules and/or pustules; residual to mild erythema; mild to moderate degree of telangiectasia may be present); 2 - Mild (Few papules and/or pustules; mild erythema; mild to moderate degree of telangiectasia may be present); 3 - Mild to moderate (Distinct number of papules and/or pustules; mild to moderate erythema; mild to moderate degree of telangiectasia may be present); 4 - Moderate (Pronounced number of papules and/or pustules; moderate erythema; mild to moderate degree of telangiectasia may be present); 5 - Moderate to severe (Many papules and/or pustules, occasionally with large inflamed lesions; moderate erythema; moderate degree of telangiectasia may be present); 6 - Severe (Numerous papules and/or pustules, occasionally with confluent areas of inflamed lesions; moderate or severe erythema; moderate or severe degree of telangiectasia may be present).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Azelaic acid (Finacea, BAY39-6251), Metronidazole (Metrogel) and Doxycycline (Oracea) in people with Papulopustular Rosacea, run by LEO Pharma at 17 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 1 inclusion and 4 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 31 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 29 Aug 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?

Nominal Change From Baseline in Inflammatory Lesion (IL) Count (Sum of Papules and Pustules) at Week 2 (LOCF: Last Observation Carried Forward) (time frame: Baseline and Week 2). 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 NCT00855595, which also lists 1 linked publication.

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 31 Mar 2020.
