A Clinical Trial to Evaluate the Efficacy of Two Acne Treatments

Phase 4

Completed

Brief Summary: The purpose of this study is to evaluate the efficacy of 2 acne treatments for 24 weeks of use in adult men and women with mild to moderate facial acne, at least 5 inflammatory lesions, and at least 10 - 100 non-inflammatory lesions.

Detailed Description: 1. To characterize the effectiveness of the acne treatment in lesion count at week 1, week 2, week 6, week 12, and week 24 as compared to baseline and compare between treatments

2. To characterize the effectiveness of the acne treatment in Investigator's Global Improvement Assessment at week 1, week 2, week 6, week 12, and week 24 as compared to baseline and compare between treatments

3. To characterize the effect of the acne treatment in clinical grading of efficacy parameters through digital images at week 6, week 12, and week 24 as compared to baseline and compare between treatments

4. To characterize the effect of the acne treatment in subject self-assessment questionnaire responses at week 1, week 2, week 6, week 12, and week 24 as compared to baseline and compare between treatments

Arm && Interventions

Group	Intervention	Description

Product B (salicylic acid)	Product B	Product B applied topically to the affected area of the skin 1 to 3 times daily.

Primary Outcome Measures

Name	Time	Method
Percent Change From Baseline in Total Lesions at Week 12	Baseline and 12 weeks	Percent change from baseline in total lesions at week 12 was assessed by investigator or designee. Investigator or designee counted and recorded the number of open comedones, closed comedones, papules, and pustules on each subject's face. Lesions were counted globally on the following facial locations/quadrants: forehead, left cheek, chin, and right cheek. Each of the following lesion types were analyzed separately for forehead, left cheek, chin, right cheek, and the total of the 4 areas: * Inflammatory acne lesions (sum of papules and pustules) * Non-inflammatory acne lesions (sum of open comedones and closed comedones) * Total lesion counts (sum of inflammatory and non-inflammatory acne lesions counts)
