Outcome Measures

Primary Outcome Measures :

1. Investigator's Global Assessment (IGA) "Success" - Week 12 [ Time Frame: Baseline and Week 12 ]
   Count and percentage of subjects achieving success in each treatment group at Week 12 using the dichotomized IGA with success defined as a score of "clear" or "almost clear" (IGA Score of 0 or 1) and a two or more grade improvement from Baseline using a five-point scale (0=clear to 4=severe).
2. Inflammatory and Non-Inflammatory Lesion Counts - Week 12 [ Time Frame: Baseline and Week 12 ]
   Absolute change from Baseline in inflammatory and non-inflammatory lesion counts in each treatment group at Week 12.

Secondary Outcome Measures :

1. Inflammatory and Non-Inflammatory Lesion Counts - Week 8 [ Time Frame: Baseline and Week 8 ]
   Absolute change from Baseline in inflammatory and non-inflammatory lesion counts in each treatment group at Week 8.
2. Percent Change in Lesion Counts - Weeks 8 and 12 [ Time Frame: Week 8 and Week 12 ]
   Percent change from Baseline in lesion counts (inflammatory and noninflammatory) in each treatment group at Weeks 8 and 12.
3. IGA "Success" - Week 8 [ Time Frame: Baseline and Week 8 ]
   Count and percentage of subjects achieving success per the IGA in each treatment group at Week 8 ("success" as defined in the primary endpoints section).
4. IGA "Clear" or "Almost Clear" - Weeks 4, 8 and 12 [ Time Frame: Weeks 4, 8, and 12 ]
   Count and percentage of subjects who are "clear" or "almost clear" (IGA Grade 0 or 1) in each treatment group at Weeks 4, 8 and 12.
