Eligibility

Inclusion Criteria:

• Diagnosis of severe primary axillary hyperhidrosis with a HDSS score of 3 or 4
• At least 50 mg of sweat production in each axilla measured gravimetrically at room temperature and at a humidity consistent with the normal climate in that area over a period of 5 minutes (patients should have acclimatized to that room for at least 30 minutes)

Exclusion Criteria:

• Hypersensitivity against glycopyrrolate
• Secondary hyperhidrosis, for example, hyperhidrosis that is secondary to other underlying diseases including hyperthyroidism, lymphoma and malaria, climacteric hyperhidrosis.
• Previous surgical treatment of hyperhidrosis including sympathectomy, surgical debulking of the sweat glands, subcutaneous tissue curettage and ultrasonic surgery.
• Botulinum toxin treatment in the prior 4 months.
• Angle closure glaucoma or its precipitation (narrow angle).
• Mycotic, other skin infections and other dermal disorder including infection at anticipated application sites in either axilla.
• Any condition or situation that, in the investigator's or sub-investigator's opinion, may interfere with the patient's participation in the study;

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose-confirming part: Absolute change in sweat production assessed by gravimetric measurement (GM) from Baseline (Day 1a) to Day 29 in the 1% GPB group compared with the placebo group.		Baseline (Day 1a), Day 29
Primary	Long-term part (only for newly recruited patients): Absolute change in sweat production assessed by GM from Baseline (Day 1b) to Week 12		Baseline (Day 1b), Week 12
Secondary	Dose-confirming part: Percentage of responders assessed by the Hyperhidrosis Disease Severity Scale (HDSS) (=2-point improvement from Baseline) on Day 29 in the 1% GPB group compared with the placebo group	The Hyperhidrosis Disease Severity Scale (HDSS) is a disease-specific, quick, and easily-understood diagnostic tool that provides a qualitative measure of the severity of the patient's condition based on how it affects daily activities. HDSS is a four item scale. A score of 1 or 2 indicates mild or moderate Hyperhidrosis. A score of 3 or 4 indicates severe Hyperhidrosis.	Day 29
Secondary	Dose-confirming part: Percentage of responders assessed by GM at Day 29 (defined by sweat reduction of =50%, =75%, and =90% compared with Baseline) in the 1% GPB group compared with the placebo group		Day 29
Secondary	Long-term part: Percentage of responders assessed by the HDSS (=2-point improvement from Baseline) at Week 12		Week 12
Secondary	Long-term part: Percentage of responders assessed by GM at Week 4 and Week 12 (defined by sweat reduction of =50%, =75%, and =90% compared with Baseline		Week 4, Week 12
