Zafgen Announces Beloranib Program Update

-Company Elects to Proceed with Data Analysis for the Pivotal Phase 3 Study in Prader-Willi Syndrome and the Phase 2b in Severe Obesity Complicated by Type 2 Diabetes-

-Open Label Extension Portion of Phase 3 Prader-Willi Syndrome Study to Continue-

BOSTON – Oct. 22, 2015 – Zafgen, Inc. (Nasdaq:ZFGN), a biopharmaceutical company dedicated to significantly improving the health and well-being of patients affected by obesity and complex metabolic disorders, today announced a clinical update for beloranib, the Company’s lead MetAP2 inhibitor product candidate.

After review of its ongoing clinical trials, the Company has elected to proceed with efficacy and safety data analysis and close the randomized portion of its Phase 3 ZAF-311 clinical trial of beloranib in patients with Prader-Willi syndrome (PWS) and its ZAF-203 Phase 2b clinical trial of beloranib in patients with severe obesity complicated by type 2 diabetes. Zafgen believes that a sufficient number of patients have completed randomized treatment in both clinical trials to assess the efficacy of beloranib and help inform next steps for the beloranib program. Following the partial clinical hold announced last week, the Company believes it can best preserve the integrity of the data in each clinical trial by closing the randomized portion of the clinical trials early. The Company, based on consultation with the U.S. Food and Drug Administration (FDA), expects ZAF-311 to remain a pivotal clinical trial. The Company expects to report top-line results from both the ZAF-311 and ZAF-203 clinical trials in the first quarter of 2016.

Zafgen will continue the six-month open label extension (OLE) of the ZAF-311 clinical trial in PWS to obtain important ongoing efficacy and safety data. As previously planned, the Company is continuing to offer an open-ended, unblinded extension study after patients have completed six months of OLE.

In consultation with the FDA, a full assessment of the safety and efficacy data from ZAF-311 will be performed to inform the design of ZAF-312, the Company’s second PWS Phase 3 clinical trial. The FDA has informed the Company that it will review the ZAF-311 clinical trial results on the basis of an abbreviated data package.

“The strategic decision to analyze results from the ZAF-311 and ZAF-203 clinical trials early allows us to better preserve data integrity by limiting dose interruption in both clinical trials, and inform the future development of this important product candidate,” said Dennis Kim, M.D., Chief Medical Officer of Zafgen. “PWS is a life-threatening and complex rare disorder that severely impacts the quality of life of both patients and their families, and we continue to believe that beloranib may have an important role in addressing hyperphagia and underlying obesity associated with this disorder. We will continue to treat, closely monitor and follow patients in the ZAF-311 extension portion of the clinical trial.”

As previously reported, Zafgen learned of a patient death in the ongoing Phase 3 ZAF-311 clinical trial of beloranib in PWS, and it subsequently received notice from the FDA that beloranib has been placed on a partial clinical hold. Although the autopsy report remains to be received, the cause of death based on the death certificate has been determined to be respiratory failure due to pulmonary emboli. However, it is not known if this event was related to treatment with beloranib.


“Patient safety is paramount and we will continue to work with regulators on current and future clinical trials of beloranib. Beloranib has demonstrated important clinical outcomes in patients with complicated and severe obesity, including patients with PWS,” said Dr. Thomas Hughes, Chief Executive Officer of Zafgen. “We look forward to analyzing results from our ZAF-311 and ZAF-203 clinical trials, and to advancing our programs. We remain committed to the PWS community and to the development of beloranib.”

About Beloranib

Beloranib is a novel, first-in-class injectable small molecule therapy with a unique mechanism of action that reduces hunger while stimulating the use of stored fat as an energy source. Beloranib is a potent inhibitor of MetAP2, an enzyme that modulates the activity of key cellular processes that control metabolism. MetAP2 inhibitors work, at least in part, by directing MetAP2 binding to cellular stress mediators, and, thus, reducing the tone of signals that drive lipid synthesis by the liver and fat storage throughout the body. In this manner, MetAP2 inhibition increases metabolism of fat as an energy source. Zafgen holds exclusive worldwide rights (exclusive of South Korea) for the development and commercialization of beloranib. Zafgen exclusively licensed beloranib from Chong Kun Dang Pharmaceutical Corporation (CKD Pharma) of South Korea.

About Prader-Willi Syndrome (PWS)

Prader-Willi syndrome (PWS), the most common known genetic cause of life-threatening obesity, results in constant and unrelenting hunger that drives patients with PWS to engage in problematic hunger-related behaviors and to gain excessive weight. As a result, many of those affected with PWS become morbidly obese and suffer significant mortality. Currently, there is no cure for this disease. Although the cause of PWS is complex, it results from a deletion or loss of function of a cluster of genes on the 15th chromosome. PWS typically causes low muscle mass and function, short stature, incomplete sexual development, and a chronic feeling of hunger that, when coupled with a metabolism that utilizes drastically fewer calories than normal, can lead to excessive eating and life-threatening obesity. PWS occurs in males and females equally and in all races, with the same incidence around the world. Prevalence estimates have ranged from 1:8,000 to 1:50,000.
