A responder was defined as a participant showing at least a 50% reduction from Baseline in mean weight of axillary sweating.	Week 4	No
Secondary	Percentage of Responders Assessed by Gravimetric Measurement at Weeks 1, 8, 12, 16, 20, and 24 in the First Treatment Phase	A pre-weighed filter paper was placed into the axilla area to collect sweat over a 5-minute period. The paper was removed and weighed to determine the amount of sweat produced. A responder was defined as a participant showing at least a 50% reduction from Baseline in mean weight of axillary sweating.	Weeks 1, 8 ,12, 16, 20, and 24	No
Secondary	Mean Weight of Axillary Sweating by Gravimetric Measurement at Baseline and Weeks 1, 4, 8, 12, 16, 20, and 24 in the First Treatment Phase	A pre-weighed filter paper was placed into the axilla area to collect sweat over a 5-minute period. The paper was removed and weighed to determine the amount of sweat produced.	Week 0 (Baseline); Weeks 1, 4, 8, 12, 16, 20, and 24	No
Secondary	Mean Percent Change From Baseline in Mean Weight of Axillary Sweating at Weeks 1, 4, 8, 12, 16, 20, and 24 in the First Treatment Phase	A pre-weighed filter paper was placed into the axilla area to collect sweat over a 5-minute period. The paper was removed and weighed to determine the amount of sweat produced. Percent change from Baseline was calculated as follows: (mean weight at each visit minus mean weight at Baseline) * 100/mean weight at Baseline.	Week 0 (Baseline); and Weeks 1, 4, 8, 12, 16, 20, and 24	No
Secondary	Percentage of Responders Assessed by the Hyperhidrosis Severity Scale (HDSS) in the First Treatment Phase	The HDSS is a 4-point scale (score range: 1-4) used to assess the impact of disease and the clinical relevance of treatment. Participants selected their underarm sweat condition from the following: 1=Never noticeable and never interferes with my daily activities, 2=Tolerable but sometimes interferes with my daily activities, 3=Barely tolerable and frequently interferes with my daily activities, and 4=Intolerable and always interferes with my daily activities. A responder was defined as a participant whose change from Baseline was equal to or less than -2.	Weeks 1, 4, 8, 12, 16, 20, 24, 28, 32, 36, and 40	No
