Rotunda’s research leads to new fat-dissolving drug


The work of ASDS Board member Adam M. Rotunda, M.D., to develop Kybella – the new fat-dissolving injectable drug – adds to a longstanding tradition of innovation among ASDS members.


Nov. 18, 2015, Rolling Meadows, Ill. – A flood of news media coverage is introducing many Americans to Kybella, the new injectable drug that melts away double-chin fat.

Adam M. Rotunda, M.D., requires no such introduction. He’s been there from the start, with his research more than a decade ago helping to set in motion Kybella’s eventual approval by the FDA this spring.

“I am excited for Kybella to become the first agent in a new frontier of injectable medications that promises to shape, contour and reduce small packets of fat without surgery,” said Rotunda, a member of the Board of Directors of the American Society for Dermatologic Surgery and founder of Newport Skin Cancer Dermatology in Newport Beach, Calif.

“Just as physicians use injectable fillers to restore volume, Kybella will become an injectable used to reduce volume,” he said.

Rotunda’s involvement traces back to 2003, when he was a dermatology resident at UCLA studying in the lab of Mike S. Kolodney, M.D., Ph.D, then Assistant Professor of Dermatology. The duo performed a series of experiments on a purported fat-dissolving chemical known then by many names: Lipodissolve, mesotherapy, injection lipolysis and phosphatidylcholine/deoxycholate (PC/DC).

The two performed multiple studies revealing that deoxycholate (DC) alone has very powerful effects on fat, identifying it as the essential, active ingredient in the PC/DC formulation, contrary to conventional thought that PC was necessary for fat dissolution. Rotunda said he was not particularly surprised by the revelation of DC’s stand-alone effects but was encouraged by the quick and convincing discovery of its profound effects on fat.

After an affirming clinical trial in 2005 investigating DC’s effects on benign tumors of fat tissue, Kolodney presented the finding at a Southern California biotech conference, which caught the attention of the founders of Kythera Biopharmaceuticals (known at the time as Aestherx). The company acquired the rights to the drug, then known as ATX-101. After the long path to FDA approval reached fruition earlier this year, Kybella played a prominent role in Allergan’s $2.1 billion acquisition of Kythera this fall.

It is little wonder that Kybella’s approval and release – the drug already is available in some areas – have generated extensive news media coverage. An eager marketplace awaits.

In the 2015 ASDS Consumer Survey on Cosmetic Dermatologic Procedures, 67 percent of respondents reported being “somewhat to extremely bothered” by excess fat under the chin and in the neck area.

Patients with minimal double-chin fat (known as submental fullness) might require only two or three treatments, whereas a patient with a much fuller neck might need up to six treatments to achieve the desired results, Rotunda said. The treatment has been rigorously tested in the neck area in more than 2,600 patients.

Patients are expected to experience “transient, mild to moderate swelling, tenderness and perhaps numbness,” but Rotunda said none of these effects are permanent and with each subsequent treatment, the effects become less severe. Local anesthesia and ice may help to make the treatment more tolerable.

Noting that “all necks are not created equal,” Rotunda said patients and physicians must learn to determine which patients are ideal treatment candidates. As with most aesthetic procedures, “Kybella is a highly personalized treatment,” he said.

Rotunda’s work in developing Kybella adds to a longstanding tradition of innovation among ASDS members. Society members have played leading roles in pioneering many of the most frequently performed cosmetic medical treatments in addition to assisting with clinical trials proving their safety and effectiveness.

“ASDS members continue to make their mark on the specialty as the leading pioneers of cosmetic medical procedures,” said ASDS/ASDSA President Naomi Lawrence, M.D. “Whether it is wrinkle-relaxing injections, soft-tissue fillers, laser procedures or body sculpting treatments, the unmatched expertise and training our members possess places them at the forefront of innovation. The new treatment for submental fat offers yet another example.”

Tracking Kybella’s progress naturally has commanded Rotunda’s attention for the past decade-plus, especially during the whirlwind of the past several months. Regardless, his thriving Southern California practice remains the focal point for Rotunda, a former valedictorian at both Cornell University and SUNY Downstate Medical Center.

“I am extremely grateful to watch the ‘deoxycholic acid baby' grow over the past 10 years,” he said. “Yet, not personally holding on to it was essential – Mike and I have passed it on to dermatologic surgeons who will offer it at their practices. We hope it will help many patients.”
