Positive topline results from ZGN-433 Phase 1b study in obesity patients

April 30, 2017

"ZGN-433 has the potential to be the first drug to produce weight loss approaching that of bariatric surgery," said Steven R. Smith, M.D., scientific director of the Translational Research Institute for Metabolism and Diabetes and professor at the Sanford-Burnham Medical Research Institute in Orlando. "Given the excellent tolerability and safety seen in this four-week study, the program shows early promise to provide a positive risk/benefit proposition. While the long-term safety and efficacy of the compound remain to be established, there is nothing in the industry drug pipeline this advanced that has shown this kind of efficacy. These early results are very encouraging, and there remains a significant unmet medical need for new obesity therapeutics that are both safe and efficacious."

"While Zafgen's understanding of the compound's mechanism of action has evolved significantly since the company's early days, MetAP2 inhibition for the treatment of obesity and diabetes appears to translate well across species," said Alan D. Cherrington, Ph.D., professor of medicine and molecular physiology and biophysics, Vanderbilt University, and former American Diabetes Association president. "These positive initial clinical and preclinical findings show that MetAP2 inhibitor actions point to utility for the treatment of severe obesity, and also show intriguing potential for use in broader indications related to control of glucose, lipid and cholesterol metabolism, including hepatic glucose intolerance, fatty liver and dyslipidemia."

Zafgen is pioneering novel obesity therapeutics to help the body regain and sustain a lean, healthy state by targeting imbalances in fat metabolism. Research has shown that fat metabolism differs between obese and lean individuals. Recent studies indicate that once a person becomes obese, the body undergoes certain changes and is "programmed" to make and store more fat. These metabolic adaptations that take place in obese people impair the normal release of fatty acids from adipose tissue and restrict the ability to stimulate formation of ketone bodies (a byproduct of the breakdown of fatty acids). Simultaneously, the body becomes much more efficient in diverting calories from food and storing them as fat.
