KYTHERA Biopharmaceuticals Submits Drug Application in Australia for Novel Submental Contouring Injectable Drug ATX-101

WESTLAKE VILLAGE, Calif., Feb. 4, 2015 (GLOBE NEWSWIRE) -- KYTHERA Biopharmaceuticals, Inc. (Nasdaq:KYTH) today announced its submission to Australia's Therapeutic Goods Administration (TGA) for ATX-101 (deoxycholic acid), its potential first-in-class treatment for improving submental fullness associated with submental (under the chin) fat. This milestone in KYTHERA's ATX-101 global development program follows regulatory applications in the U.S., Canada and Switzerland.

"KYTHERA is committed to making ATX-101 available in key markets to treat submental fullness, an often-cited yet under-addressed condition that can occur regardless of a person's weight," said Keith Leonard, president and chief executive officer, KYTHERA. "We plan additional submissions to regulatory authorities in other countries during the remainder of this year."

The application in Australia is supported by results from two pivotal Phase III trials: REFINE-1 and REFINE-2. Data from the trials, first reported in 2013, demonstrated that the majority of ATX-101 patients had a visible reduction in fat under the chin and reported significant improvement in the visual and emotional impact of treatment.

The global facial aesthetics market is estimated to reach $4.7 billion annually by 2018.
