Inclusion criteria

* Medical diagnosis of severe primary axillary hyperhidrosis with a PRHS score of ≥5 with symptoms for at least 3 months before Screening * At least 50 mg of sweat production in each axilla measured gravimetrically over a period of 5 minutes at room temperature along with a humidity consistent with the normal climate in that area (patients have to acclimatize to that room for at least 30 minutes before the measurement) * Adolescents of both sexes aged 12 to 17 years (until study completion) with a body mass index percentile ≥10 and ≤90 (according to Kromeyer-Hauschild et al 2001) * Local tolerability assessment (skin reaction) score = 0

Exclusion criteria

* Secondary hyperhidrosis, ie, hyperhidrosis that is secondary to other underlying diseases such as (but not limited to) hyperthyroidism, lymphoma, and malaria * Previous surgical treatment of hyperhidrosis including sympathectomy, surgical debulking of the sweat glands, subcutaneous tissue curettage, ultrasonic surgery, microwave treatment (miraDry), or laser treatment * Botulinum toxin treatment for the treatment of axillary hyperhidrosis in the previous 4 months * Hypersensitivity to glycopyrrolate, or to any of the excipients of the investigational medicinal product (IMP)

Design outcomes

Primary

MeasureTime frame
Number of patients with Adverse Drug Reaction during treatmentBaseline to Day 57
Number of patients with a local tolerability assessment (skin reaction score) >0 during treatmentBaseline to Day 57
Αbsolute change in GP plasma concentration from Baseline to Day 15Baseline to Day 15

Secondary

MeasureTime frameDescription
Relative change in total sweat production assessed by GM from Baseline to Day 29 and Day 57Baseline to Day 29 and Day 57
Relative change in total sweat production assessed by GM from Day 29 to Day 57Day 29 to Day 57
Proportion of responders assessed by GM at Day 29 and Day 57Day 29 and Day 57
Absolute change in patient-rated hyperhidrosis severity (PRHS) score from Baseline to Day 29 and Day 57Baseline to Day 29 and Day 57The patient-rated hyperhidrosis severity (PRHS) score will be assessed by asking the following question: How did you perceive your underarm sweating in the past 24 hours? Please rate it on a scale from 0 (no sweating at all) to 10 (worst sweating that you ever had)
Absolute change in patient-rated hyperhidrosis severity (PRHS) score from Day 29 to Day 57Day 29 to Day 57The patient-rated hyperhidrosis severity (PRHS) score will be assessed by asking the following question: How did you perceive your underarm sweating in the past 24 hours? Please rate it on a scale from 0 (no sweating at all) to 10 (worst sweating that you ever had)
Absolute change in the Children's dermatology life quality index (CDLQI) score from Baseline to Day 29 and Day 57Baseline to Day 29 and Day 57The Children's dermatology life quality index (CDLQI) is a simple 10-question questionnaire that assesses the burden of hyperhidrosis. It is validated for children aged 5-16 years. The answers to the questions are generally scored on a 4-point scale: 'very much' = 3, 'quite a lot' = 2, 'only a little' = 1, 'not at all' or question unanswered = 0. The CDLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more impairment of the child's life is experienced.
Absolute change in logarithmic values of total sweat production assessed by GM from Baseline to Day 29Baseline to Day 29
Absolute change in GP plasma concentration from Baseline to Day 8Baseline to Day 8
Absolute change in GP plasma concentration from Day 8 to Day 15Day 8 to Day 15
Frequency, severity, and relation of ADRs, SAEs, TEAEs, SUSARs, and discontinuations due to TEAEsScreening to 14 Days after End of Treatment
Local tolerability based on the skin reaction scoreDay 1, Day 29, Day 57/End of Treatment and 14 Days after Day 57/End of TreatmentLocal tolerability at the application sites will be assessed and evaluated by the investigator using a skin reaction score: 'No evidence of irritation' = 0, 'Minimal erythema, barely perceptible' = 1, 'Definite erythema, readily visible; minimal edema or minimal popular response' = 2, 'Erythema and papules' = 3, 'Definite edema' = 4, 'Erythema, edema, and papules' = 5, 'Vesicular eruption' = 6, 'Strong reaction spreading beyond test site' = 7, 'Folliculitis' = 8.
Neurological assessment of anticholinergic effects by a 4-point scale7 to 4 Days before Baseline, Day 15, Day 29, Day 43, Day 57/End of TreatmentThe occurrence of possible anticholinergic effects including dry mouth, dry eyes, blurred vision, red eyes, constipation, micturition disorder, drowsiness, and concentration difficulties is rated on a 4-point scale: 'severe intensity' = 3, 'moderate intensity' = 2, 'mild intensity' = 1, 'no evidence' = 0.
