Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pharmacodynamic activity of TAR-0520 gel: 1. Skin blanching visual Score: Assessments will be done on the chest and the face minizones, 4 hours after products applications at Day 1, Day 3 and Day 5. 2. Chromametry: Chromametry assessments will be done on the chest and the face before products applications and 2 hours and 4 hours after products applications on Day 1, 3, 5, 19 and 23 or 26. In addition, chromametry assessments will be done on the chest and the face before products applications and 4 hours after products applications on Day 8, D12 and D15. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Local tolerance of TAR-0520 when applied to the face assessed visually at each visit on each test zone 2. A safety assessment will be conducted for all subjects at the screening visit (from the Informed consent signature) and every subsequent visit. The safety parameters in this study include AEs, physical examination, vital signs assessments and a local tolerance evaluation on treated minizones. | — |
