Sienna Labs announced today that the U.S. Patent and Trademark Office issued U.S. Patent No. 8,906,418 covering, among other aspects, methods of using the company's targeted plasmonic therapy (TPT) platform for localizing thermal damage to sebaceous glands and hair, a key mechanism for their investigational acne treatment and hair removal indications.
Sienna Labs' invention, entitled "THERMAL TREATMENT OF A PILOSEBACEOUS UNIT WITH COATINGS THAT FACILITATE SELECTIVE REMOVAL FROM THE SKIN SURFACE," specifically relates to using gold, silver, nickel, platinum, or titanium plasmonic nanoparticles to localize thermal damage to sebaceous glands, hair, and other components of the pilosebaceous unit. Several claims of the patent protect key methods for applying these plasmonic nanoparticles to the skin, delivering them specifically into the pilosebaceous unit, and activating the particles with light to localize thermal damage to the gland and hair follicle. Included in certain claims are methods for delivering particles specifically into the pilosebaceous unit using mechanical vibration devices including massage or ultrasound. Other key claims relate to the use of coatings that facilitate selective removal from the skin surface, a key feature enabling the safety and efficacy of TPT treatment.
Todd Harris, Sienna Labs' Chief Executive Officer, stated, "We are pleased to secure this key patent protecting our TPT platform to treat conditions involving the pilosebaceous unit. This patent along with 5 other patents recently issued in the U.S. provides us with a very strong foundation to bring our technology to market."
