Clinical dermatology company Sienna Biopharmaceuticals closes second Series A financing

July 19, 2016
Dermatology and aesthetics technology company Sienna Biopharmaceuticals has completed a second closing of its Series A financing.

Sienna Biopharmaceuticals (Westlake Village, CA), a clinical stage company that focuses on dermatology and aesthetics, has completed a second closing of its Series A financing, securing an additional $12 million in equity capital and bringing the total capital raised to approximately $46 million.

The company is developing novel approaches to treat skin based on plasmonic resonance, originally developed at Sienna Labs (Carlsbad, CA) under the leadership of Todd Harris, Ph.D. The technology, called Silver Plasmonic Therapy (SPT), entails using a proprietary topical solution containing patented plasmonic particles that interact with the light emitted by existing medical laser systems, allowing controlled targeting of microstructures in the skin. The company believes the treatment has the potential to meet unmet needs in the areas of acne, hair removal, and potentially other areas.

The additional investment proceeds are targeted to fund the company's pharmaceutical research and advance its business development efforts. Clinical trials are already underway and the company is evaluating additional potential indications.
