Sienna Biopharmaceuticals, Inc. (NASDAQ:SNNA), a clinical-stage biotechnology company, today announced positive topline results from its pivotal trial of SNA-001 in conjunction with an 810 nm Diode laser, involving 65 patients. SNA-001, a topical pre-treatment to standard laser hair removal, was studied in women and men with white, gray, blonde, light red and light brown hair. The data showed SNA-001 met the primary endpoint of non-inferiority in hair reduction (-17.5 percent with SNA-001+Laser compared to -1.1 percent with vehicle+Laser following six treatment sessions). In additional analyses, SNA-001 was statistically superior compared to vehicle+Laser, demonstrating up to a 31 percent reduction of light hair from baseline1.
