Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Treatment-Related Adverse Events | 56 Weeks | An adverse event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. A Treatment-Related Adverse Event is an Adverse Event determined by the investigator to be causally related to the study medication. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With at Least a 2-Grade Decrease From Baseline on Both Clinician Erythema Assessment (CEA) and Subject Satisfaction Assessment (SSA) Using 5-Point Scales | Baseline, Day 1 Hours 3 and 6, Week 4 Predose and Hours 3 and 6, Week 12 Predose, Week 26 Predose and Hours 3 and 6, Week 39 Predose, Week 52 Predose and Hours 3 and 6, Week 54 Predose | The investigator assessed the participant's overall severity of erythema in the treatment area by using the 5-point CEA scale with photonumeric guide where: 0=clear skin with no signs of erythema (best) to 4=severe erythema; fiery redness (worst). A decrease in the score indicates improvement. The participant assessed their overall severity of rosacea facial redness in the treatment area by using the 5-point SSA scale with photoguide where: 0=no signs of unwanted redness (best) to 4=severe redness (worst). A decrease in the score indicates improvement. The percentage of participants with at least a 2-grade decrease (improvement) on both CEA and SSA from Baseline was evaluated over the 6-hour evaluation period (hours 3 and 6) post-dose. |

Percentage of Participants With at Least a 2-Grade Decrease From Baseline on Both Clinician Erythema Assessment (CEA) and Subject Satisfaction Assessment (SSA) Using 5-Point Scales
The investigator assessed the participant's overall severity of erythema in the treatment area by using the 5-point CEA scale with photonumeric guide where: 0=clear skin with no signs of erythema (best) to 4=severe erythema; fiery redness (worst). A decrease in the score indicates improvement. The participant assessed their overall severity of rosacea facial redness in the treatment area by using the 5-point SSA scale with photoguide where: 0=no signs of unwanted redness (best) to 4=severe redness (worst). A decrease in the score indicates improvement. The percentage of participants with at least a 2-grade decrease (improvement) on both CEA and SSA from Baseline was evaluated over the 6-hour evaluation period (hours 3 and 6) post-dose.
