Feasibility Study: Safety and Efficacy of the Ulthera® System for Treatment of Axillary Hyperhidrosis

Not Applicable

Completed

• Conditions: Hyperhidrosis
• Interventions: Drug: Ulthera System Treatment; Drug: Sham treatment

• Registration Number: NCT01713673
• Lead Sponsor: Ulthera, Inc

Brief Summary

Up to 20 subjects will be treated. Subjects will receive two (2) bilateral Ultherapy™ or Sham treatments of the axilla. The study hypothesis is that subjects who receive Ultherapy™ treatment will have a greater reduction in axillary sweating compared to subjects receiving Sham treatments. Follow-up visits will occur at 7 and 14 days following treatment #1, and at 7, 14, 30, 60 and 90 days following treatment #2. At each follow-up visit, assessments will be completed to compare the amount of axillary sweating compared to baseline.

Detailed Description

This study is a prospective, single-center, randomized, sham-controlled, blinded pilot clinical trial. Subjects will be randomly assigned to one of two treatment groups in a 2:1 randomization scheme, two (2) subjects assigned to receive Ultherapy™ treatment to every one subject assigned to receive Sham treatment.

Gravimetric measurement of sweat production and starch iodine tests will be performed, and Hyperhidrosis Disease Severity Scale (HDSS) scores will be obtained, prior to treatment and at each follow-up visit. Patient satisfaction will also be assessed. Sham treated subjects will have the option of continuing to Stage II and receive active treatment after completion of their Stage I 90 day study visit.

In a protocol amendment, the initial Stage I study cohort, excluding Sham treated subjects who opt to continue to Stage II, will be recruited to complete one long-term follow-up visit at 365 days following subjects' second study treatment. The same follow-up assessments will be completed to compare the amount of axillary sweating compared to baseline.

• Previous botulinum toxin treatment of the axilla in the past year
• Expected use of botulinum toxin for the treatment of any other disease during the study period
• Known allergy to starch powder or iodine
• Secondary hyperhidrosis, for example, hyperhidrosis that is secondary to other underlying diseases including hyperthyroidism, lymphoma and malaria
• Previous surgical treatment of hyperhidrosis including sympathectomy, surgical debulking of the sweat glands, subcutaneous tissue curettage and ultrasonic surgery
• Unwillingness to wash off deodorants and abstain use 72 hours prior to treatments or assessments
• History of previous Ultherapy™ treatment to the axilla
• Subjects with a history of a bleeding disorder
• Use of cholinomimetics, anticholinergics, or any oral herbal medicine treatments for hyperhidrosis
• Inability to withhold use of antiperspirants and deodorants, or any other topical treatments for hyperhidrosis within 72 hours prior to study treatments and assessments

Arm && Interventions

Group	Intervention	Description
Active Treatment	Ulthera System Treatment	Subjects receive Ulthera System Treatments according to the pre-defined Ulthera® System energy settings.
Sham Treatment	Sham treatment	Subjects will receive Sham treatments using the Ulthera® System with the energy set to 0.00 Joules.

Primary Outcome Measures

Name	Time	Method
Percentage of subjects with HDSS scores of 1 or 2	30 days post-treatment #2	The HDSS scale is a qualitative measure of the severity of the condition based on how it affects subjects' daily activities. Subjects select the statement that best reflects their experience with underarm sweating on a 4 point scale, with 1 = sweating never noticeable and 4 = sweating is intolerable.

Secondary Outcome Measures

Name	Time	Method
Reduction in spontaneous axillary sweat production	Participants will be followed to 365 days post treatment #2	Assessed by a gravimetric method as measured by a 50% reduction or more compared to baseline.
Subject Satisfaction	Participants will be followed to 365 days post-treatment #2	Subject satisfaction will be measured using a Patient Satisfaction Questionnaire (PSQ.)
