Clinical Trial Summary

The Sahara Study is a study to evaluate the safety and effectiveness of the N-SWEAT Patch for use in subjects with excessive axillary sweating, or primary focal axillary hyperhidrosis.

Description:

The Sahara Study is intended to evaluate the safety and effectiveness of the N-SWEAT Patch for use in subjects with excessive axillary sweating, or primary focal axillary hyperhidrosis. Safety of the N-SWEAT Patch will be confirmed by assessing the occurrence of local skin reactions, treatment-related adverse events (AEs) and Serious Adverse Events (SAEs). Demonstration of effectiveness will be assessed by a significant improvement (reduction) in Hyperhidrosis Disease Severity Score (HDSS) in subjects treated with the N-SWEAT Patch. Secondary and additional endpoints based on complementary clinical instruments, including Quality of Life Measures (QOL) and Gravimetric Sweat Production GSP), have been included to further demonstrate performance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety of the N-SWEAT Patch	Number of patients with Adverse Events and/or Skin reactions following patch treatment	4 weeks
Primary	Effectiveness of the N-SWEAT Patch to Change Subjects From an HDSS 3 or 4 at Baseline to HDSS 1 or 2 at 4 Weeks	Achievement of Hyperhidrosis Disease Severity Scale (HDSS) score of 1 or 2 at 4 weeks.; HDSS is a disease-specific diagnostic tool that provides a qualitative measure of the severity of the patient's condition based on how it affects daily activities. HDSS 3 or 4 are generally considered to have a clinically significant case and those with HDSS 1 or 2 are considered to have mild to no evidence of hyperhidrosis.; SCALE: 1 - My sweating is never noticeable and never interferes with my daily activities 2- My sweating is tolerable but sometimes interferes with my daily activities 3- My sweating is barely tolerable and frequently interferes with my daily activities 4- My sweating is intolerable and and always interferes with my daily activities	4 weeks
Secondary	Mean Change in the Quality of Life. Assessed by Evaluating How Much Sweat Bothers or Impacts the Daily Life of Patients (a Higher Score Means More Bother and More Impact)	Two Quality of Life (QoL) Assessments were conducted as part of this endpoint. The Level of Bother: Subjects were asked how much their sweat bothered them on a Scale of 1 (not at all bothered by sweating) to 5 (extremely bothered by sweating). The Impact of Sweat on Daily Activities: Subjects were asked how much their sweating impacts their daily activities on a scale of 1 (not at all impacted) to 5 (extremely impacted).; The mean improvement of each of these was calculated by comparing the mean baseline level to the mean level at 4 weeks. The mean change in the level of improvement was analyzed for significance. A larger decrease in these levels, i.e. less bother and less impact, (indicated by a larger negative number) will show the most improvement in QoL.	4 weeks
Secondary	Percentage of Patients With a Mean Change in Gravimetric Sweat Production (GSP) Indicating That Sweating After Treatment is Cut in Half From Pre-treatment Sweat	Gravimetric Sweat Production (GSP) measures the amount of sweat that is produced in a 5-minute period. The percentage of treated subjects with at least a 50% reduction in mean GSP (mean of both axilla) from baseline to 4 weeks was analyzed for this endpoint.	4 weeks
Secondary	Percentage of Patients With a 2-point Change in HDSS to Show That Sweat is Less Clinically Significant After Treatment	Patients with a 2-point decrease in HDSS indicate improvement in sweating.; HDSS is a disease-specific diagnostic tool that provides a qualitative measure of the severity of the patient's condition based on how it affects daily activities. HDSS 3 or 4 are generally considered to have a clinically significant case and those with HDSS 1 or 2 are considered to have mild to no evidence of hyperhidrosis.; SCALE: 1 - My sweating is never noticeable and never interferes with my daily activities 2- My sweating is tolerable but sometimes interferes with my daily activities 3- My sweating is barely tolerable and frequently interferes with my daily activities 4- My sweating is intolerable and always interferes with my daily activities	4-weeks
