PARIS, France I February 1, 2013 I At the International Master Course on Aging Skin (IMCAS) in Paris, France, Bayer presented at a symposium the results of two pivotal European Phase-III studies with ATX-101, an investigational injectable drug for the reduction of unwanted fat deposits under the chin known as submental fat (SMF). Based on efficacy measures, analysis of the Phase-III data demonstrated that ATX-101 significantly reduced SMF compared to placebo.(1,2) These trials are part of the ATX-101 clinical development program conducted jointly by Bayer and KYTHERA Biopharma-ceuticals since 2010.
ATX-101 reduces subcutaneous fat by localized fat-cell-membrane disruption followed by elimination from the treated area, and is the first drug undergoing comprehensive evaluation in a clinical trial setting for the reduction of submental fat. Compared to placebo, ATX-101 led to significant improvements in clinician-reported measurements of SMF, supported by objective caliper measurements of SMF thickness. Moreover, patients reported significant reductions in SMF with ATX-101 compared to placebo, and were significantly more satisfied with their chin appearance and their treatment as a result. These positive Phase-III results confirm earlier findings of two Phase-II studies demonstrating positive results for ATX-101.(3,4) Up to now, the aesthetic correction of fatty deposits under the chin has predominantly been performed using surgical procedures involving possible undesirable side effects for the patient. These results were also presented at the IMCAS as poster.(2)
“Both of the Phase-III studies demonstrated the injectable drug ATX-101 to be well tolerated by patients; they yielded a clinically relevant and statistically significant reduction in unwanted fat deposits under the chin,” said Dr. Benjamin Ascher, Plastic Surgeon, Paris Academy, Director of the Aesthetic Surgery Clinic IENA in Paris and scientific director of the IMCAS, in his presentation at the Paris symposium.
“The positive results of the Phase-II and Phase-III studies for ATX-101 make us confident that we are on the right road with our commitment to enter the aesthetic dermatology market,” said Kemal Malik, M.D., Member of the Bayer HealthCare Executive Committee and Head of Global Development. “Based on evidence-based experience, ATX-101 represents a promising candidate for the reduction of submental fat.”
The European ATX-101 Phase-III studies
The two identical Phase-III multi-center, randomized, double-blind, placebo-controlled trials enrolled 723 patients and were conducted in 57 centers across the United Kingdom, France, Germany, Belgium, Spain and Italy. In both trials, patients received one of two dosing regimens (1 mg/cm2 or 2 mg/cm2) or placebo, administered monthly into the submental fat area for up to four treatment cycles, and were followed up for 12 weeks post treatment. The efficacy of ATX-101 compared to placebo was assessed using a validated 5-point Clinician-Reported Submental Fat Rating Scale. The Patient-Reported Outcomes were evaluated on the basis of a 7-point Subject Satisfaction Rating Scale, a validated 5-point Patient-Reported Submental Fat Rating Scale and a Patient-Reported Submental Fat Impact Scale. Calipers, an objective measurement of submental fat thickness, were also used to assess the reduction of submental fat.
Adverse events were primarily limited to the injection site; most were temporally associated with treatment. The most common adverse events were pain, swelling, numbness, bruising and induration. Occurrence was transient and predominantly mild to moderate in intensity. No systemic treatment-related adverse events were reported.
About ATX-101
ATX-101 is a potential first-in-class injectable drug candidate under clinical investigation for the reduction of unwanted submental fat. ATX-101 is a proprietary formulation of synthetic deoxycholic acid, a well-characterized endogenous compound that is present in the body to promote the natural breakdown of dietary fat. ATX-101 reduces subcutaneous fat by localized fat-cell-membrane disruption followed by elimination from the treated area. This mechanism may enable a non-surgical alternative for the reduction of unwanted subcutaneous fat. Clinical studies to date have demonstrated that ATX-101 is well tolerated and may effectively reduce localized fat in the submental region (i.e. under the chin). In August 2010 Bayer Consumer Care AG signed a licensing and development collaboration agreement with KYTHERA, thereby obtaining commercialization rights to ATX-101 outside the US and Canada. KYTHERA and Bayer are collaborating on the development of ATX-101 in Europe.
