What this trial studies

This study evaluates the safety and efficacy of the Morpheus8 Applicator, a radio frequency device, for treating primary focal hyperhidrosis of the axillae. Participants will be divided into an active group receiving two treatments with the device and a sham group receiving placebo treatments. The procedure will take place in a controlled environment, and follow-up visits will occur at one, three, and six months post-treatment to assess outcomes. The study aims to determine if this innovative approach can effectively reduce excessive sweating in the underarm area.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with primary focal axillary hyperhidrosis and a quality-of-life rating of 3 or 4 on the Hyperhidrosis Disease Severity Scale.

Not a fit: Patients with secondary hyperhidrosis caused by medications, infections, malignancy, or endocrine disorders will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from excessive underarm sweating.

How similar studies have performed: While the use of radio frequency technology for hyperhidrosis is a novel approach, similar studies have shown promise in treating other dermatological conditions.
