The drug is sodium deoxycholate for injection, code-named ATX-101 was developed for the treatment of lipomas – benign tumors of subcutaneous adipose tissue, as well as other unwanted fatty growths, such as a double chin. This substance, which is a salt of one of the bile acids, emulsifies fats, destroying their excess deposits

ATX-101 (a first-in-class injectable drug being studied for the reduction of localized fat. ATX-101 is a proprietary formulation of deoxycholate  a well-studied endogenous compound that is present in the body), a facial injectable drug for the reduction of unwanted fat under the chin, or submental fat. V. Leroy Young, MD, FACS, presented the initial results at the American Society for Aesthetic Plastic Surgery (ASAPS) 45th Annual Aesthetic Meeting in Vancouver, British Columbia, on May 4, 2012.

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.

KYTHERA Biopharmaceuticals Inc. 02 MAR 3013,  announced positive interim results from a Phase IIIb multi-center open-label study (ATX-101-11-26) to evaluate the safety and efficacy of ATX-101 an investigational injectable drug for the reduction of unwanted submental fat (SMF) commonly known as double chin. The results presented at the Late Breaking Research Symposium at the 71st American Academy of Dermatology (AAD) Annual Meeting in Miami Beach Fla. found that ATX-101 is well-tolerated and may be effective in reducing SMF by both clinician and patient reported outcome measures. The ATX-101 global clinical development program has enrolled more than 2500 total patients of which more than 1500 have been treated with ATX-101.

“In my practice patients often request a non-surgical way to treat their submental fat or undesirable double chin” said investigator Susan Weinkle MD FAAD a board certified dermatologist and affiliate clinical professor at the University of South Florida. “For these patients double chin is often resistant to diet and exercise. The results of this study suggest that microinjections of ATX-101 can reduce submental fat without worsening skin laxity.”

ATX-101 is a proprietary synthetically-derived formulation of deoxycholic acid (DCA) a naturally-occurring molecule found in the body that aids in fat metabolism. In this open-label Phase IIIb study interim results three months after the last ATX-101 treatment found:

  • Reduction of submental fat
    • 87 percent of patients achieved at least a one-grade improvement from baseline on the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)
    • Similarly 83 percent of patients achieved at least a one-grade improvement on the Patient-Reported Submental Fat Rating Scale (PR-SMFRS)
  • 96 percent of patients had unchanged or improved skin laxity based on the clinician rated Submental Skin Laxity Grading Scale (SMSLG)
  • 95 percent of patients were satisfied with treatment based on the Global Post Treatment Satisfaction Scale
  • Adverse events were of mild to moderate intensity transient and primarily associated with the treatment area

Topline results from this study were announced in November 2012. As previously announced 71.3 percent of subjects had at least a one-grade improvement on the CR-SMFRS / PR-SMFRS composite and 14.0 percent had at least a two-grade improvement on the same composite measure.

These results are based on a multicenter 12-month open-label Phase IIIb study conducted at 21 sites across the United States evaluating 165 adults who received injections of ATX-101 for up to six treatments at four-week intervals. Patients received ATX-101 (2 mg/cm2) by subcutaneous microinjections directly into their SMF and were evaluated three months after their last treatment. The study population includes females (77.6 percent) and males (22.4 percent) with a mean age of 47 who report at least moderate SMF and dissatisfaction with the appearance of their chin. All Fitzpatrick Skin Types an industry standard scale to categorize skin tone are represented.

“We are pleased with these ATX-101 study results” said Patricia S. Walker M.D. Ph.D. chief medical officer KYTHERA Biopharmaceuticals Inc. “These results along with efficacy analyses in double-blind placebo-controlled studies support ATX-101 entering the market as potentially the first medical aesthetic drug approved for the reduction of submental fat.”

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 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 subject 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 U.S. and Canada. Bayer recently completed two pivotal Phase III trials of ATX-101 in Europe for the reduction of submental fat. Topline results from these trials were reported in the second quarter of 2012. KYTHERA completed enrollment in its pivotal Phase III clinical program for ATX-101 in more than 1000 subjects randomized to ATX-101 or placebo in 70 centers across the United States and Canada in August 2012. The Company expects to release topline results in mid-2013.

    I’ve been browsing online more than three hours today, yet I never found any interesting article like yours.

    It’s pretty worth enough for me. In my opinion, if all webmasters and bloggers made good content
    aas you did, the internet will be much more useful than ever before.
