A Study to Evaluate Clinical Effect, Pharmacokinetics , Safety, and Tolerability of Umeclidinium in Palmar Hyperhidrosis Subjects

A Phase 2a Study to Evaluate the Clinical Effect, Pharmacokinetics, Safety and Tolerability of Topically Applied Umeclidinium in Subjects With Primary Palmar Hyperhidrosis

Umeclidinium (UMEC) is a potent pan-active long-acting muscarinic antagonist (LAMA). It is anticipated that topical administration of UMEC will block stimulation of muscarinic receptors, thereby reducing the overproduction of sweat in subjects who suffer from hyperhidrosis. This study will assess the clinical effect, pharmacokinetics, safety and tolerability of topically applied UMEC following once daily topical administration, for 28 days, to the palms, in subjects with primary palmar hyperhidrosis. The study will also investigate if topically applied UMEC, at the highest possible concentration, will decrease palmar hyperhidrosis with a systemic anticholinergic adverse event profile similar to or below that observed with inhaled administration. This is a double blind (Sponsor unblind), repeat dose, randomized, parallel group, placebo controlled study. Study will enrol up to 55 subjects.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Umeclidinium once daily (QD) 1.85%; Subjects will apply UMEC topically once daily (2microliter [µL]/centimeter [cm]^2) to both the hands (palm and fingers) using graduated syringe at night before bedtime for 28 days. Randomization will be 4:1 (UMEC 1.85%: vehicle)	Drug: Umeclidinium; Umeclidinium (GSK573719) 1.85% will be supplied as a clear, colourless solution, free from visible particulates, for topical application. Each subject total daily dose will be calculated as per study reference manual (SRM) using subject's hand area. A single dose of study treatment will be based on the size of the subject's hand in order to provide coverage of approximately 2µL/ cm^2. 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.
Placebo Comparator: Vehicle QD; subjects will apply vehicle topical once daily (2µL/cm^2) to both the hands (palm and fingers) using graduated syringe at night before bedtime for 28 days.	Drug: Vehicle; 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. A single dose of study treatment will be based on the size of the subject's hand in order to provide coverage of approximately 2µL/ cm^2

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Posterior Probability That the Response Rate is Greater Than 50%	A response rate is defined as percentage of participants who achieved at least 30 percent decrease from Baseline in gravimetric sweat production at Day 29. Baseline was latest assessment prior to first dosing. A response rate of greater than 50 percent was considered to be clinically meaningful (greater than 50 percent of participants achieving at least 30 percent decrease from Baseline in gravimetric sweat production at Day 29). The posterior probability that response rate in sweat production is greater than 50 percent was analyzed. The evaluation was performed using Bayesian analysis, in which latest pre-dose value was used as Baseline.	Baseline and Day 29
Percentage of Participants With at Least 30 Percent Reduction From Baseline in Sweat Production at Day 29	Percentage of participants at Day 29 post-treatment with at least a 30 percent reduction from Baseline in sweat production measured by gravimetry. Participants remained at rest for at least 20-30 min before the measurements in order to reduce external interference. The latest pre-dose value was considered as Baseline value. The summary of percentage of participants from both the cohorts with at least 30 percent reduction from Baseline in sweat production was presented for the average of both palms.	Baseline and Day 29

SAE was defined as any untoward medical occurrence that, that results in death, life-threatening, requires hospitalization or prolongation of existing hospitalization, disability/incapacity, any a congenital anomaly/birth defect or other situations at any dose.	Up to Day 43
Number of Participants With Abnormal Electrocardiogram (ECG) Findings	Single measurements of 12-lead ECGs were obtained using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and corrected QT (QTc) intervals. ECG values were recorded as abnormal not clinically significant (NCS) and abnormal clinically significant (CS). The participants with data available at specified time points were represented by n=x in the category titles.	Day 1, 15 and 29
Number of Participants With Abnormal Values of Hematological Parameters	Blood samples were collected from participants for evaluation of hematology parameters by Potential Clinical Chemistry Criteria. The data was presented for only those hematology parameters for which abnormal values were found (neutrophils and hemoglobin) . During the analysis, no participant in the higher dose cohort- vehicle group, nor in the lower dose cohort (for both UMEC and vehicle groups) had abnormal hematology values that met the pre-specified criteria for potential clinical importance. Hence, the data for only higher dose cohort was presented. The measurements taken at Day 29 were presented. Participants were counted in the category for their values greater than (>) reference (ref) range high and less than (<) ref range low. The participants with data available at specified time points were represented by n=x in the category titles.	Day 29
Number of Participants With Abnormal Values of Chemistry Parameters Assessment as a Safety Measure	Blood samples were collected to analyze the abnormal clinical chemistry parameters by Potential Clinical Importance Criteria. The data was presented for only those parameters for which abnormal values were found (calcium, alanine aminotransferase [ALT]). Participants in the higher dose cohort (UMEC group) had abnormal calcium values and for ALT, the abnormal values were found in lower dose cohort (UMEC group). Hence, data was presented only for these specific cohorts. Participants were counted in the category for their values > ref range high and < ref range low. The measurements taken at Day 1, Day 15 and Day 29 were presented. The participants with data available at specified time points were represented by n=x in the category titles. "n=0" in category titles represents that the data was not available for participants in respective category or arm.	Day 1, 15 and 29

Results have been reported in a semi-quantitative manner as negative, Trace, 1+, 2+, 3+ and 4+, indicating proportional concentrations of the analyte in the urine sample. Abnormal laboratory values have been presented in the table. The participants with data available at specified time points were represented by n=x in the category titles.	Day 1, 15 and 29
Change From Baseline in Body Temperature Assessment as a Safety Measure	Body temperature was measured as a vital sign in seated position, after 5 min rest. Baseline value was the latest assessment prior to first dosing. Change from Baseline value was calculated by post-dose visit value minus Baseline value. The participants with data available at specified time points were represented by n=x in the category titles.	Baseline, Day 15, 27, 28 and 29
Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP)	Vital signs including SBP and DBP were measured in a seated position, after 5 minutes rest.
