20:00 EDT 26 Jul 2015 | Globe Newswire

WESTLAKE VILLAGE, Calif., July 27, 2015 (GLOBE NEWSWIRE) -- KYTHERA Biopharmaceuticals, Inc. (NASDAQ:KYTH) today announced it has received authorization from Health Canada to market BELKYRA™ “for improvement in the appearance of moderate to severe convexity or fullness associated with submental fat (SMF) in adults.” BELKYRA™ is a non-surgical treatment for improving the appearance and profile of submental fullness—more commonly known as “double chin,” a facial aesthetic condition that affects both women and men. BELKYRA™ was recently launched in the U.S. under the brand name KYBELLA™.

“We are pleased to offer BELKYRA™ for patients who are seeking a non-surgical solution to improve the appearance of their submental fullness, sometimes referred to as a double chin, an oft-cited, but undertreated facial feature,” said Keith Leonard, President and Chief Executive Officer of KYTHERA Biopharmaceuticals. “The authorization of BELKYRA™ in Canada is another milestone for KYTHERA and for physicians who now have a treatment for fat under the chin."

BELKYRA™ is supported by a global clinical development program that includes over 20 clinical studies with more than 2,600 patients worldwide, of which over 1,600 have been treated with BELKYRA™.ii In the pivotal Phase III studies, 68.2 percent of patients responded to BELKYRA™ based on a composite of validated physician and patient measurements.iii

“A broad range of my patients, both women and men of varying ages, complain of submental fullness because it makes them look older and heavier. This facial aesthetic condition is often resistant to diet and exercise and may be caused by aging, genetics or weight gain,” said Vince Bertucci, M.D., FRCPC, Co-director of the Dermatologic Laser Surgery and Cosmetic Dermatology Fellowship at the University of Toronto and a consulting dermatologist at Women’s College Hospital; Clinical Investigator in the BELKYRA™ clinical trials and President of the Canadian Dermatology Association. “BELKYRA™ will provide my patients with a non-surgical solution that can be tailored to their individual treatment goals for an improved chin profile.”

In the clinical trials, the most commonly reported side effects of BELKYRA™ were in the treatment area and included swelling, bruising, pain, numbness, redness, tingling or itchiness, a sensation of warmth, or hardness.

The facial aesthetics market, which includes non-surgical injectable treatments like BELKYRA™, is poised for continued growth – in fact, it is estimated that consumers worldwide will spend $4.7 billion on these types of procedures by 2018.iv

BELKYRA™ is administered by injections into the fat under the chin, customized to the aesthetic treatment goals of the patient and the physician. Many patients experienced visible results in two to four treatments.v Patients should be assessed before each treatment session; this includes ensuring there is sufficient SMF. Up to six treatments may be administered. Once the aesthetic response is achieved, retreatment is not expected.

Health professionals must receive specialized training before using BELKYRA™ and understand the relevant submental anatomy and associated neuromuscular structures in the area involved and any alterations to the anatomy due to prior surgical or aesthetic procedures.

About Submental Fullness

Submental fullness is a common yet undertreated condition that can detract from an otherwise balanced and harmonious facial appearancevi – leading to an older and heavier look.vii Submental fullness can impact a broad range of adults, including both women and men, and can be influenced by several factors such as aging, genetics and weight gain and is often resistant to diet and exercise alone.viii


BELKYRA™ deoxycholic acid injection is used in adults to improve the appearance and profile of moderate to severe amounts of fat under the chin, a condition that is commonly referred to as a double chin. BELKYRA™ is a non-human and non-animal formulation of deoxycholic acid, a naturally-occurring molecule in the body that aids in the breakdown and absorption of dietary fat.ix When injected into subcutaneous fat, BELKYRA™ causes the destruction of fat cells. Once destroyed, those cells cannot store or accumulate fat.x

BELKYRA™ is indicated for improvement in the appearance of moderate to severe convexity or fullness associated with SMF in adults.

The safe and effective use of BELKYRA™ for the treatment of subcutaneous fat outside the submental region or for patients with mild or extreme SMF has not been established and is not recommended.  Health professionals administering BELKYRA must receive specialized training before using BELKYRA and understand the relevant submental anatomy and associated neuromuscular structures in the area involved and any alterations to the anatomy due to prior surgical or aesthetic procedures.
