Last Updated: 2018-10-11

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 28 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-11-23
• Study Completion Date: 2016-02-25

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.

Study Groups

Umeclidinium

Subjects will receive umeclidinium once daily before bedtime for 14 days.

Group Type: EXPERIMENTAL

Umeclidinium

Intervention Type: DRUG

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.

Vehicle

Subjects will receive vehicle once daily before bedtime for 14 days.

Group Type: PLACEBO_COMPARATOR

Vehicle

Intervention Type: DRUG

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.

Eligibility Criteria

Inclusion Criteria

• Between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• A Hyperhidrosis Disease Severity Scale (HDSS) score of 3 or 4.
• A diagnosis of primary, axillary hyperhidrosis, defined as excessive, bilateral, axillary sweating of at least 6 months duration without apparent cause and with at least 1 of the following characteristics: subject has a positive family history of hyperhidrosis, hyperhidrosis is bilateral and relatively symmetrical, subject experienced first episode of hyperhidrosis before 25 years of age, subject experiences cessation of focal sweating during sleep.
• A baseline gravimetric assessment of at least 50 milligrams sweat produced at rest by each axilla during a period of 5 minutes (measurements can be repeated up to 2 times on two different days, screening and baseline visits, but subjects need to qualify on at least one occasion).
• Male.
• A female is eligible to enter and participate in the study if she is of:

Non-child bearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g., age appropriate, > 45 years, in the absence of hormone replacement therapy. In questionable cases for women < 60 years of age, a blood sample with simultaneous follicle stimulating hormone and estradiol falling into the central laboratory's postmenopausal reference range is confirmatory.

OR Child bearing potential, has a negative pregnancy test at screening, and agrees to one of the following acceptable contraceptive methods used consistently and correctly (i.e., in accordance with the approved product label and the instructions of the physician) for the duration of the study: abstinence; oral contraceptive, either combined or progestogen alone; injectable progestogen; implants of levonorgestrel; estrogenic vaginal ring; percutaneous contraceptive patches; intrauterine device (IUD) or intrauterine system (IUS) that meets the standard operating procedure effectiveness criteria as stated in the product label; male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject; double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository

• If subjects have shaved axilla or removed hair by other means within the last 2 weeks, there should be minimal to no irritation.
• Capable of giving signed informed consent which includes compliance with the pre-specified requirements and restrictions.

Exclusion Criteria

• Unstable or life threatening cardiac disease. In the opinion of the investigator, use should only be considered if the benefit is likely to outweigh the risk in conditions such as: myocardial infarction or unstable angina in the last 6 months, unstable or life threatening cardiac arrhythmia requiring intervention in the last 3 months, New York Heart Association (NYHA) Class IV heart failure.
• Diagnosis of narrow-angle glaucoma, urinary retention, prostatic hypertrophy or bladder neck obstruction that in the opinion of the study investigator or GlaxoSmithKline (GSK) Medical Monitor would prevent use of an anticholinergic and therefore study participation.
• Irritation or active infection of axillary area, including sweat glands.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones that the investigator deems clinically significant).
• Alanine aminotransferase (ALT) > 2 x Upper Limit of Normal (ULN) and bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin < 35%) at screening.
• Corrected QT Interval (QTc) > 450 milliseconds (ms) or QTc > 480 ms in subjects with Bundle Branch Block.

The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB), Fridericia's formula (QTcF), and/or another method, machine-read or manually over-read.

The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial.

For purposes of data analysis, QTcB, QTcF, another QT correction formula, or a composite of available values of QTc will be used.

• Prior surgical procedure for hyperhidrosis.
• Axillary treatment with radiofrequency and microwave devices.
• Treatment with axillary iontophoresis within 4 weeks prior to Baseline/Day 1.
• Menopausal women who have had symptoms of menopause such as sweating or flushing within 3 years of the study.
• Used any prohibited medication within the indicated washout period.
• Any history of allergy or hypersensitivity to any anticholinergic/muscarinic receptor antagonist, sympathomimetic.
• Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment.
• A positive pre-study drug/alcohol screen at screening.
• A positive test for Human Immunodeficiency Virus (HIV) antibody at screening.
• The subject has participated in a clinical trial and has received an investigational product within the following time periods prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
• Exposure to more than 4 investigational medicinal products within 12 months prior to the first dosing day.
• Any other condition which, in the judgment of the investigator, would put the subject at unacceptable risk for participation in the study (e.g., subjects with renal failure).
• Subjects with clinically significant abnormalities in laboratory values for which, according to the investigator, study participation would put the subject at undue risk.
• Abnormal findings on screening electrocardiogram (ECG) deemed clinically significant by the Investigator.
• Women who are pregnant or lactating or are planning on becoming pregnant during the study.

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 65 Years
• Eligible Sex: ALL
