Kythera Biopharmaceuticals Receives $33.3 Million in Payments From Bayer HealthCare

Published: Jun 05, 2012

LOS ANGELES--(BUSINESS WIRE)--KYTHERA Biopharmaceuticals, Inc. (KYTHERA) today announced that it has received a $15.8 million payment from Bayer Consumer Care AG (Bayer) under the terms of their August 2010 collaboration arrangement to develop and commercialize KYTHERA’s injectable drug candidate, ATX-101, outside the United States and Canada. In addition, KYTHERA received €14.1 million ($17.5 million) to fund certain further global development activities of ATX-101 under the terms of the collaboration arrangement. The payments were triggered by Bayer’s decision to pursue continued development and regulatory approvals for ATX-101 after receipt of positive results from pivotal European Phase III clinical trials.

About ATX-101

ATX-101 is a potential first-in-class injectable drug candidate under clinical investigation for the reduction of localized fat. ATX-101 is a proprietary formulation of synthetic sodium deoxycholate, a well-characterized component of human bile that is naturally occurring in the body and promotes the breakdown of dietary fat. ATX-101 is designed to be a locally-injected drug that causes proximal, preferential destruction of adipocytes, or fat cells, with minimal effect on surrounding tissue. Based on clinical trials conducted to date, ATX-101 has exhibited significant, meaningful and durable results in the reduction of submental fat, which commonly presents as an undesirable “double chin.” These results correspond with patient satisfaction measures demonstrating meaningful improvement in perceived chin appearance.

In August 2010, Bayer signed a licensing and collaboration development agreement with KYTHERA, thereby obtaining development and commercialization rights to ATX-101 outside of the United States and Canada. KYTHERA initiated its pivotal Phase III clinical program, with planned enrollment of 1,000 patients, for ATX-101 in the United States and Canada in March 2012 and expects to report results from these trials in 2013. These trials are expected to form the basis for a new drug application for approval of ATX-101 in the United States and Canada.
