Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in GAGS (Global Acne Grading System) index score at 12 weeks | 12-week | TOTAL SCORE = Nose S x 1 + Chin S x 1 + Front S x 2 + Right cheek S x 2 + Left cheek S x 2 + Torso S x 3 \[Severity (S): 0 = Absence; 1 = Comedones; 2 = Papules; 3 = Pustules; 4 = Nodules\] SCORE: 0 = Clean; 1-18 = Mild; 19-30 = Moderate; 31-38 = Severe; \> 38 = Very severe |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| AGSS (Acne Global Severity Scale) index score | 0, 6 and 12-week | Score between 0 and 5: 0 = Clean = Normal and clear skin without evidence of acne 1. = Almost clean = There are some non-inflammatory lesions, with uncommon and non-inflamed papules 2. = Mild = few inflammatory lesions (no nodule-cystic lesions) 3. = Moderate = Noninflammatory lesions predominate, but multiple inflammatory lesions appear (nodule-cystic lesions may be present) 4. = Severe = Inflammatory lesions predominate (nodule-cystic lesions may be present) 5. = Very severe = Highly inflammatory lesions predominate (several nodule-cystic lesions) |
| Number of acne lesions | 0, 6 and 12-week | Number of non-inflammatory, inflammatory and total acne lesions. |
| Patient subjective evaluation | 0, 6 and 12-week | Min score (Best) = 6 Max score (Worst) = 30 |
| Adherence to treatment | 12-week | Compliance rate (in percentage) calculated as the number of leftover capsules divided by the total number of days between visits. |
| Treatment safety assessed by number of adverse events | 12-week | Number of adverse events that occur during the treatment period. |
