What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percent Change From Baseline in Inflammatory Lesion Count at Week 12	Percent change from baseline in inflammatory lesion count at week 12 was reported. Inflammatory lesions included facial inflammatory lesions of rosacea (that is [i.e.] papules and pustules) which were defined as follows: Papule - a small, solid elevation less than 1.0 centimeter (cm) in diameter; and Pustule - a small, circumscribed elevation of the skin, which contains yellow white exudates. Papules and pustules were counted separately on each of the 5 facial regions (forehead, chin, nose, right cheek and left cheek). Notably, nodules (i.e. circumscribed, elevated, solid lesions more than 1.0 cm in diameter with palpable depth) were not included in the count of inflammatory lesions.	Baseline, Week 12

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily had a causal relationship with this treatment.

A SAE was any untoward medical occurrence that at any dose: results in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or was a congenital anomaly/birth defect.
