  Purpose

A study to determine if using 2 acne products in the morning is as safe and efficacious as using one product in the morning and one product in the evening.


Condition Intervention Phase
Acne Vulgaris
Drug: benzoyl peroxide wash
Drug: Tretinoin gel
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: A Clinical Assessment of the Use of RETIN-A MICRO (Tretinoin Gel) Microsphere, 0.04% in a Pump Dispenser and a 5% Benzoyl Peroxide Wash Used in the Morning Compared to the Use of RETIN-A MICRO 0.04% Pump Nightly and a 5% Benzoyl Peroxide Wash in the Morning For the Treatment of Facial Acne Vulgaris

Primary Outcome Measures:
  • Change From Baseline in Total Facial Acne Lesion Count [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    Total Facial Acne Lesion Count is the sum of non-inflammatory and inflammatory lesions, plus nodules/cysts. Change from Baseline is calculated as the value after Baseline minus the baseline value, and negative values indicate improvement.


Secondary Outcome Measures:
  • Change From Baseline in Inflammatory and Non-Inflammatory Lesion Counts and Their Totals [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    Between group comparison with Last Count Carried Forward (LOCF) of Inflammatory Facial Acne Lesion Count (the sum of papules and pustules), Non-Inflammatory Facial Acne Lesion Count (the sum of open and closed comedones), and their Total (the sum of Non-inflammatory and Inflammatory lesions).

  • Measurement of Success [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]

    Number of subjects achieving success according to dichotomized Investigator Global Assessment (IGA) using criteria of grades 0 or 1, or improvement of 2 grades from baseline score. Possible grades from 0-6 are described as follows:

    0 = Clear, 1=Almost Clear, 2=Mild, 3=Mild to Moderate, 4=Moderate, 5=Moderately Severe, 6=Severe.

Detailed Description:

Approximately 240 subjects will be enrolled in this randomized, multi-center study. Following satisfaction of entry criteria and screening procedures, all subjects will receive RETIN-A MICRO PUMP 0.04% and a 5% Benzoyl Peroxide wash (OTC) for the entire 12-week treatment period. Subjects will be randomized to either both morning treatments (test) or to the morning/evening treatment (active control). Subjects will be assessed at baseline, at week 3, week 6 and again at the end of therapy, week 12 for number and type of individual lesions and safety. At selected sites, photographs will be taken at the same time points. At Week 12 subjects will be assessed for Investigator's Global Assessment of Acne Severity. The investigator will conduct all of the lesion counts, global assessments and safety assessments.
