There are many different factors that cause acne. So combination treatment using different medications that can address these different factors is commonly used to treat acne. Fixed-dose combination clindamycin phosphate 1.2% and tretinoin 0.025% gel and benzoyl peroxide 6% foaming cloths are both used to treat acne. This study will evaluate the use of the medications when used together.

Condition Intervention Phase
Acne Vulgaris
Drug: clindamycin phosphate 1.2%/tretinoin 0.025% gel alone
Drug: clindamycin phosphate 1.2%/tretinoin 0.025% gel plus benzoyl peroxide 6% foaming cloths
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: A Pilot Study to Evaluate the Efficacy of Fixed Dose Combination Clindamycin Phosphate 1.2%/Tretinoin 0.025% Gel Alone Versus Fixed Dose Combination Clindamycin Phosphate 1.2%/Tretinoin 0.025% Gel Plus Benzoyl Peroxide 6% Foaming Cloths in the Treatment of Facial Acne Vulgaris

Further study details as provided by Joshua Zeichner, Mount Sinai School of Medicine:

Primary Outcome Measures:
  • Change in PGA scores of patients using combination clindamycin phosphate 1.2%/tretinoin 0.025% gel with or without benzoyl peroxide 6% foaming cloths for facial acne [ Time Frame: Weeks 2, 4, 8, 12 ]
    The primary efficacy endpoint will be "Treatment Success", a static endpoint defined as a score of 0 (clear) to 1 (almost clear) at Week 12 (final study visit) by PGA scoring system.

Secondary Outcome Measures:
  • Change in Postinflammatory hyperpigmentation score at each study visit and from baseline to final visit. [ Time Frame: Weeks 2, 4, 8, 12 ]
    Change in PIH score from baseline will be assessed. (based on a 6 point scale)

  • Total number of adverse events. [ Time Frame: Weeks 2, 4, 8, 12 ]
    Safety/drug-tolerance evaluated at each visit (total number of adverse events)

  • Change in Subject Self Assessment Scoring Scale [ Time Frame: Weeks 2, 4, 8, 12 ]
    Patient rates current severity of their acne.

  • Change in Acne-Specific Quality of Life Questionnaire (Acne-QoL) [ Time Frame: Weeks 2, 4, 8, 12 ]
    Acne-QoL as completed by patient.

Estimated Enrollment: 40
Study Start Date: July 2011
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: clindamycin phosphate 1.2%/tretinoin 0.025% gel alone Drug: clindamycin phosphate 1.2%/tretinoin 0.025% gel alone
Once daily application of the clindamycin phosphate 1.2%/tretinoin 0.025% gel in the evening
Active Comparator: clindamycin / tretinoin gel plus benzoyl peroxide Drug: clindamycin phosphate 1.2%/tretinoin 0.025% gel plus benzoyl peroxide 6% foaming cloths
wash face with the benzoyl peroxide foaming cloth then rinse. then apply clindamycin phosphate 1.2%/tretinoin 0.025% gel. both done in the evening.
