Percentage of Responders Assessed by Gravimetric Measurement at Week 4 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.
Time frame: Week 4

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.
