             applicable.

          -  (2) Healthy male or non-pregnant females, ≥18 years-of-age with a clinical diagnosis
             of rosacea with persistent (non-transient) facial erythema.

          -  (3) Ability to follow study instructions and complete subject diary without

             form of birth control from the day of the first dose administration to 30 days after
