Brella SweatControl Patch

Brellalogo 1681230072420 HR 1In April 2023, the U.S. FDA cleared for use the Brella™ SweatControl Patch™ for the treatment of excessive underarm sweating (primary axillary hyperhidrosis). Brella™ is a product of Candesant Biomedical, headquartered in San Francisco, CA. This is the first new hyperhidrosis treatment FDA-ok'd since 2018. 

The Brella™ patch is a prescription product designed and cleared to be applied at a healthcare provider’s office or clinic for approximately 3 minutes and works via a method called targeted alkali thermolysis (TAT).

Candesant’s TAT technology is based on the principle that heat is generated when sodium meets water. The result is that when the Brella™ sodium patch is applied to the underarm, there’s an interaction between the water in sweat and the sodium in the patch that generates a targeted amount of heat, causing microthermal injury to the sweat glands that inactivates those glands for a period of time. The process is non-invasive and does not involve needles. Results have been reported to last 2 to 4 months.

The FDA’s clearance of Brella™ was based on data from a randomized, double-blind, multicenter study that included 110 adult patients with primary axillary (underarm) hyperhidrosis. Patients had baseline Hyperhidrosis Disease Severity Scale (HDSS) scores of 3 or 4, which showed that excessive sweating frequently or always interfered with their daily lives. Patients in the study then received treatment with Brella™ or with a sham (fake or placebo) patch for up to 3 minutes on each underarm. Afterwards, patients were evaluated weekly for 12 weeks (~3 months), and again at 24 weeks (~6 months) post-treatment.

Results were presented, earlier in 2023, at the American Academy of Dermatology Annual Meeting and showed that 64% of patients treated with the patch achieved Hyperhidrosis Disease Severity Scale improvement as compared with 44% with placebo. Measured sweat production decreased by more than 50% for most (60%) of treated patients.

There were no reported serious or severe adverse events (side effects) among the study participants. Eighty percent of people in the study had no side effects at all and those who did experienced slight redness or slight swelling that resolved within two weeks or less.

The Brella™ study results “are exciting,” says Dr. David Pariser, professor at the Eastern Virginia Medical School Department of Dermatology and founding member of the International Hyperhidrosis Society, “because they demonstrate consistent, statistically significant, and clinically meaningful improvements across the measured hyperhidrosis parameters.”

According to Candesant, Brella™ will be available in certain areas of the U.S. in mid 2023 through a “Brella Early Experience Program.” The initial healthcare offices able to provide Brella™ through this program will be dermatology and plastic surgery practices with prior experience treating patients with excessive sweating. Later, Brella™ will be launched more generally in the U.S. Information about availability outside the U.S. is not yet available. To find clinicians offering Brella, use the clinician finder. You can also join Candesant's mailing list for updates on Brella's rollout. 

How much will it cost? That's not entirely clear but Niquette Hunt, CEO of Candesant has said she expects doctors will charge about the same for one session with the patch as they would for a high-end, in-office facial or chemical peel. The average cost of a chemical peel in the US, according to the American Society of Plastic Surgeons, is about $500.  But, there can be additional office visit costs, etc. IHhS spoke with one aesthetic practice in Texas that indicated they would provide Brella for a total cost of about $350. This is, of course, just one example and not indicative of widespread pricing. 

Can Brella be used on other sweaty body areas beyond the underarms? Some experts hint there may be off-label potential for the use of Brella on different body parts. The makers of Brella say they are looking into this possibility.
