Botanix's Sofdra Gel for Hyperhidrosis Gets FDA Approval

Hyperhidrosis, the third largest dermatology market after acne and atopic dermatitis, affects around 10 million individuals in the U.S. alone. This condition, characterized by excessive sweating beyond what is necessary for temperature regulation, can severely impact the quality of life of those affected, particularly when it involves primary axillary hyperhidrosis, which targets the underarms. The effects of this condition can extend to work productivity, social interactions, and emotional well-being.

For years, treatments for this condition have remained stagnant. However, Botanix Pharmaceuticals has entered the scene with a promising new solution. Their topical gel, Sofdra, recently received FDA approval for treating primary axillary hyperhidrosis in patients nine years and older. Sofdra stands out as it is the first new chemical entity specifically approved for this condition in many years.

Current treatments for hyperhidrosis include AbbVie’s Botox injections and various formulations of glycopyrrolate. However, these treatments often come with side effects such as dry mouth, dry eyes, and urinary retention due to their less targeted action. Matt Callahan, the founder and board executive director of Botanix, highlighted that Sofdra’s more targeted approach could lead to fewer side effects, positioning it as a significant advancement in hyperhidrosis treatment.

The approval of Sofdra followed two phase 3 clinical trials involving 701 patients. The results showed that the gel provided significant improvements in both the Gravimetric Sweat Production scale and the Hyperhidrosis Disease Severity Measure-Axillary score. These clinically meaningful results underscore the effectiveness of Sofdra in managing this challenging condition.

Reaching the 10 million potential U.S. patients with primary axillary hyperhidrosis presents a unique challenge. Less than half of these individuals have an official diagnosis, and many are actively seeking treatment online rather than visiting dermatologists. Botanix plans to leverage a robust digital strategy, including telemedicine, to reach these patients. This approach aims to address the social stigma and lack of awareness among dermatologists about the condition.

“This is a condition that people often don’t discuss openly and that dermatologists may not be fully informed about,” Callahan explained. “We aim to address this gap with our telemedicine approach, offering better service and fulfillment options for patients.”

Despite these challenges, the potential market for Sofdra is vast. The gel is Botanix’s first commercial product and is expected to be priced competitively with existing treatments. For example, the prescription wipe Qbrexza has an average retail price of $771. Callahan emphasized that this competitive pricing, coupled with Sofdra's unique benefits, makes it a compelling option for patients.

Moreover, about 90% of individuals with hyperhidrosis experience excessive sweating in other areas of the body, indicating significant potential for future label expansions. Callahan also describes Botanix as a “hidden gem” on the Australian Stock Exchange, with ambitions to become a leading dermatology company in the U.S. The company, based in Pennsylvania and Arizona, is also developing treatments for acne and rosacea.

Botanix’s CEO, Howie McKibbon, M.D., referred to the FDA approval as a “transformative event” for the company, marking its transition from a development stage to a revenue-generating entity. The company plans to initiate an early patient experience program in the third quarter of this year, with a broader launch expected in the fourth quarter.

This development represents a significant step forward in the treatment of primary axillary hyperhidrosis, offering new hope and options for millions of sufferers.
