Conditions: Hyperhidrosis
Keywords: Primary Axillary Hyperhidrosis GSK573719 Hyperhidrosis Disease Severity Scale (HDSS) Topical PRO Hyperhidrosis Symptom Severity Measure (HSSM) Umeclidinium
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 28
Healthy volunteers: no

Brief summary:
This is a double blind (sponsor unblind), repeat dose, randomized, parallel group, placebo controlled study to assess the pharmacokinetic parameters, safety, tolerability, and clinical effect of topically applied umeclidinium following once daily topical administration to axilla for 14 days in subjects with primary axillary hyperhidrosis. This study will determine whether topically applied umeclidinium can decrease hyperhidrosis without systemic anticholinergic effects (ie. in the range or lower to those obtained after inhaled route) at the highest possible concentration.

Subjects will be dosed by site staff each night immediately before bedtime for 14 days. Subjects will complete gravimetric and Hyperhidrosis Disease Severity Scale (HDSS) measurements, patient reported outcomes (PRO), safety assessments, and/or pharmacokinetic sampling. Follow up visits will occur on days 15, 16, 19, 23 and 28. The total duration of the study will be approximately 6 to 8 weeks. The study is planned to enroll approximately 24 subjects.

Detailed description:

Arms:
arm 1: Subjects will receive umeclidinium once daily before bedtime for 14 days. arm 2: Subjects will receive vehicle once daily before bedtime for 14 days.

Interventions: intervention 1: Umeclidinium intervention 2: Vehicle
Intervention descriptions: intervention 1: Umeclidinium (GSK573719) 1.85% will be supplied as a clear, colorless solution, free from visible particulates, for topical application. This formulation will be available at a concentration of 18.5 milligrams (mg) umeclidinium parent per gram. 2 mg of this formulation will be applied per square centimeter of the axilla, once a day at night before going to bed for 14 days. The total amount of formulation applied daily to both axillae is expected to range between approximately 204 and 680 mg. Total daily dosage of the active pharmaceutical ingredient (umeclidinium parent) to both axillae will range between approximately 3.8 and 12.6 mg. If certain pre-specified criteria for safety and tolerability are met, consideration will be given to decreasing the dose by decreasing the concentration of the topical formulation to 1.15% for the remaining subjects. This lower strength formulation will contain 11.5 mg parent per gram. intervention 2: The vehicle will be supplied as a clear, colorless solution, free from visible particulates, for topical application. This formulation will be similar to the umeclidinium formulation except that it will be devoid of the umeclidinium parent. 2 mg of the vehicle will be applied per square centimeter of the axilla, once a day at night before going to bed for 14 days. The total amount of vehicle applied daily to both axillae is expected to range between approximately 204 and 680 mg.
