About this study

Official title: A Multi-center, Randomized, Double-blind, Vehicle-Controlled, Phase 2 Study of the Safety and Efficacy of Benzoyl Peroxide/Clindamycin Gel and Tazarotene Cream When Used in Combination in the Treatment of Acne Vulgaris

Benzoyl peroxide, clindamycin and tazarotene are known to be effective treatment alternative for acne vulgaris. The purpose of this study is to assess the safety and efficacy of a combination product including these actives for the treatment of acne vulgaris.

You may be suitable to take part in this study because you have acne vulgaris on your face. Acne vulgaris usually affects the face, but it can also affect the skin on the chest, arms, legs, and back.

Read the detailed description

The study subjects must have acne vulgaris and will apply study drug to their face for 12 weeks.

Study visits will occur at baseline (day 1) and at weeks 2, 4, 8, and 12. Subjects will be assessed at every visit to determine how the study drug is working. Safety will be assessed by evaluation of adverse events (AEs), vital signs, physical examinations, and withdrawals from the study.

What is being measured

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

  1. Absolute Change in Lesion Counts (Total, Inflammatory, and Non-inflammatory) From Baseline to Week 12

    The investigator or designee took count of inflammatory lesions (papules, pustules, nodules and cysts [only post-Baseline]) (ILC), noninflammatory lesions (open and closed comedones) (NILC) and total lesions (TLC) at Baseline, Weeks 2, 4, 8, and 12. Lesion counts were confined to the face. Each of 3 lesion counts (total, inflammatory and non-inflammatory) was analyzed using an analysis of covariance (ANCOVA) model with terms for treatment, center, Baseline value and treatment-by-center interaction. If the interaction was not significant at 0.1 level, this interaction was excluded in ANCOVA model. Day 1 (Visit 1) was defined as Baseline. Only participants available at specified timepoints were analyzed (represented by n=X in the category titles).

    Measured: Baseline and up to Week 12

  2. Proportion of Participants With a Minimum 2-grade Improvement in the Investigator's Static Global Assessment (ISGA) Score From Baseline to Week 12

    An ISGA was obtained at Baseline and at Weeks 2, 4, 8, and 12. The scores range from 0-5 (0=clear skin with no inflammatory or non-inflammatory lesions; 5=very severe with many non-inflammatory and inflammatory lesions and more than a few nodular lesions (may have cystic lesions). The higher score indicates more severe. The area considered for the ISGA was confined to the face. When possible, the same efficacy assessor performed all ISGA assessments on the same participant at all visits. Day 1 (Visit 1) was defined as Baseline. Only participants available at specified time points were analyzed.

    Measured: Baseline and up to Week 12

Secondary outcomes (2)
  1. Percent Change From Baseline to Week 12 in Each of 3 Lesion Counts (Total, Inflammatory, and Non-inflammatory)

    The investigator or designee took count of inflammatory lesions (papules, pustules, nodules and cysts) (ILC), noninflammatory lesions (open and closed comedones) (NILC) and total lesions (TLC) at Baseline, Weeks 2, 4, 8, and 12. Lesion counts were confined to the face. Each of 3 lesion counts (total, inflammatory and non-inflammatory) was analyzed using an analysis of covariance (ANCOVA) model with terms for treatment, center, Baseline value and treatment-by-center interaction. If the interaction was not significant at 0.1 level, this interaction was excluded in ANCOVA model. Day 1 (Visit 1) was defined as Baseline. Only participants available at specified timepoints were analyzed (represented by n=X in the category titles).

    Measured: Baseline and up to Week 12

  2. Proportion of Participants With an ISGA Score of 0 or 1 at Week 12

    An ISGA was obtained at Baseline and at Weeks 2, 4, 8, and 12. The scores range from 0-5 (0=clear skin with no inflammatory or non-inflammatory lesions; 5=very severe with many non-inflammatory and inflammatory lesions and more than a few nodular lesions (may have cystic lesions). The higher score indicates more severe. The area considered for the ISGA was confined to the face. When possible, the same efficacy assessor performed all ISGA assessments on the same participant at all visits. Day 1 (Visit 1) was defined as Baseline. Only participants available at specified time points were analyzed.

    Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Benzoyl peroxide gel, Clindamycin gel and Tazarotene cream in people with Acne Vulgaris, run by Stiefel, a GSK Company at 16 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 6 inclusion and 6 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 6 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 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 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.

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 6 Mar 2017). 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?

Absolute Change in Lesion Counts (Total, Inflammatory, and Non-inflammatory) From Baseline to Week 12 (time frame: Baseline and up to Week 12). The study lists 2 primary outcomes in all. 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 6 Mar 2017.
