Trial Outcomes & Findings for Evaluation of the Ulthera System for Treating Axillary Hyperhidrosis (NCT NCT03320096)

NCT ID: NCT03320096

Last Updated: 2019-07-10

Results Overview

Treatment success was defined as a reduction on the HDSS score from a value of 3 or 4 at baseline to a 1 or 2 at 30-day post second treatment. The HDSS was a validated scale used for primary axillary/underarm hyperhidrosis participants. HDSS provides a qualitative measure of the severity of participant's condition based on how it affects their daily activities. It is a 4-point scale (1-4) with scores as: 1 (underarm sweating was never noticeable and never interferes with daily activities); 2 (underarm sweating was tolerable but sometimes interferes with daily activities); 3 (underarm sweating was barely tolerable and frequently interferes with daily activities); and 4 (underarm sweating was intolerable and always interferes with daily activities).

Ultherapy Treatment
Participants received two dual-depth Ultherapy treatment to each axilla at a treatment depth of 3.0 millimeter (mm) using 7-megahertz (MHz) transducer with 0.30 joules (J) of energy on Days 0 (Treatment 1) and 30 (Treatment 2). Participants were administered treatment in 3 inch\*4 inch grid, in at least 12 treatment squares. At each treatment visit, participants received a minimum of 720 treatment lines to each axilla (minimum of 1440 total lines of treatment for both axillae), delivering 60 treatment lines per treatment square.

PRIMARY outcome

Timeframe: Day 60 (30 days post second treatment)

Population: All evaluable treated participants in FAS who received a complete or partial study treatment and completed a follow-up visit at Day 30 post second treatment. The FAS was the subset of participants in SES for whom primary efficacy variable was available. The SES was the subset of all participants who were exposed to study treatment at least once.

Treatment success for gravimetric sweat production test was defined as a 50% or more reduction in spontaneous sweat production compared to baseline at 30 days and 90 days post second treatment. Gravimetric sweat production was measured using a pre-weighed filter paper placed into the axilla for a period of 5 minutes. The paper was removed and weighed and rate of sweat production was calculated in milligram per 5 minute (mg/5 min) based on the difference in end-weight and pre-weight.

Improvement for the starch iodine test was defined as a reduction in the dark blue starch iodine area, both the left and right axilla needed to show improvement for a participant to be classified as improved. The starch iodine test was used to assess the area involved in excessive sweating by visually identifying areas that were actively producing sweat. The test was performed by applying iodine solution to the axilla and allowing the solution to dry. After drying, starch was sprinkled on the area. The light-brown iodine color turns dark purple as iodine-starch complexes form in the liquid medium with the sweat rising to the surface of the affected area. Starch iodine test was captured with digital images.
