Design outcomes

Primary

MeasureTime frame

The responder is defined as the perspiration amount is reduced by 50% or more as compared with the baseline in any item of the ventilation capsule method or the weight measurement method.

Secondary

MeasureTime frame
Responder rate of perspiration at all evaluation points after administration (responder rate measured after 6 weeks from first administration is the main evaluation), mean perspiration weight, rate of change from baseline of perspiration weight, HDSS responder rate (Percentage of subjects whose HDSS score improved by 2 points or more from baseline), The amount of change from the baseline of HDSS, the total score of the score of DLQI, the score of each area of DLQI score, the change of the score of each question of DLQI score from baseline, subject's satisfaction and duration of effect.
