About this study
Official title: Regimen of Tazorac .1% Gel & Minocycline Cap in Tx of Individuals w/Acne Vulgaris: Effects of Maintenance Therapy on Duration of Improvement of Tazorac .1% Gel Used in Conjunction w/Placebo Cap Compared w/Minocycline Cap Used in Conjunction w/Either Tazorac .1% Gel or Vehicle Gel
The purpose of the study is to compare the efficacy of three maintenance regimens (topical tazarotene, oral minocycline, or both) in sustaining improvement in acne.
Read the detailed description
For many years antibiotic therapy has been the backbone of therapy for inflammatory acne. However, topical retinoids also offer efficacy against inflammatory acne and the combination of a topical retinoid and an antibiotic can result in faster and more complete clearing of inflammatory lesions than either drug alone.
The reduced sensitivity of Propionibacterium acnes to antibiotics is a growing problem. Resistance is a major issue not only because it can result in treatment failure but also because of concerns that it may potentially be transferred to other bacteria that anti-acne antibiotics are used used against. One of the most important factors predisposing to the development of resistant strains of propionibacterium acnes is the prolonged use of antibiotics. Therefore, in order to help minimize the development for such resistance, it is evident that maintenance strategies for acne should aim to minimize the long-term use of antibiotics.
Topical retinoids are a rational choice for maintenance therapy due to their activity on microcomedones (the precursor for all acne lesions). Nevertheless, there is a paucity of data evaluating this use in a maintenance setting. The aim of this study was to determine whether patients with moderate to severe inflammatory acne who have achieved a good level of clearance (eg>/= 75%) can maintain the improvement in their acne using maintenance therapy. THe study compared the efficacy of three maintenance therapies (topical tazarotene, oral minocycline, and topical tazarotene plus oral minocycline) in sustaining the clinical improvement attained after initial topical tazarotene plus oral minocycline therapy.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 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 15 Dec 2005. 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Global improvement from baseline at week 24. 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 15 Dec 2005.
