BOSTON, March 19, 2015 (GLOBE NEWSWIRE) -- 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 its fourth quarter and full year 2014 financial results.

Zafgen 2014 and Early 2015 Business Highlights

  • Announced positive results from a Phase 2a clinical trial of beloranib in patients with hypothalamic injury-associated obesity (HIAO), a rare condition that is also a difficult-to-treat severe form of obesity, in January 2015
  • Two U.S. patents owned by Zafgen have issued during 2014 and 2015 that relate to methods of treating obesity using dosing regimens of beloranib, and one U.S. patent issued in 2014 that relates to compositions of beloranib
  • Added to the NASDAQ Biotechnology Index (Nasdaq:NBI) in December 2014
  • Raised approximately $230 million through a successful initial public offering (IPO) in June 2014 and a follow-on public offering in January 2015

"We are very pleased with our accomplishments for the fourth quarter of 2014 and moreover, the year as a whole, which has been one of the most productive in our Company's history. We have made substantial progress in the clinical development of beloranib in multiple indications, all in continued support of our mission of bringing life-changing treatment options to patients affected by obesity and obesity-related disorders," said Dr. Thomas Hughes, Chief Executive Officer of Zafgen.

"With promising data in hand from our recent Phase 2a proof of concept trial (ZAF-221) in patients with HIAO, we look forward to readouts from our bestPWS (ZAF-311) Phase 3 study in Prader-Willi syndrome, and our Phase 2b trial (ZAF-203) in patients with severe obesity complicated by type 2 diabetes," said Dr. Hughes.

"We were pleased to have completed our IPO in June 2014 and our recent follow-on offering in January 2015 bringing in total net proceeds of approximately $230 million," said Patricia Allen, Chief Financial Officer of Zafgen. "We are investing this capital in the development of beloranib in multiple indications along with bringing forth our ZAF-839 program in nonalcoholic steatohepatitis, or NASH, and second-generation molecules to beloranib. We are also expanding our organization to deliver on our multiple development programs and create the foundation of our commercialization activities in anticipation of approval of beloranib in Prader-Willi syndrome."

Fourth Quarter and Full Year 2014 Financial Results

Cash and Cash Equivalents and Marketable Securities

As of December 31, 2014, the Company had cash and cash equivalents and marketable securities totaling $115.5 million.

In January 2015, the Company sold an aggregate of 3,942,200 shares of common stock through an underwritten public offering at $35.00 per share, before underwriting discounts, which included the full-exercise of the underwriters' option to purchase an additional 514,200 shares of common stock at $35.00 per share. The net proceeds to the Company were approximately $129.5 million.

Net Loss

The Company reported a net loss for the fourth quarter of 2014 of $10.9 million, or $0.48 per share, compared to a $3.8 million net loss, or $5.35 per share, for the fourth quarter of 2013. The Company reported a net loss for the year ended December 31, 2014 of $36.5 million, or $3.00 per share, compared to a $14.0 million net loss, or $19.53 per share, for the full year ended December 31, 2013. The weighted average common shares (basic and diluted) outstanding used to compute net loss per share were 22,783,817 for the fourth quarter of 2014, compared to 729,391 for the fourth quarter of 2013. The weighted average common shares (basic and diluted) outstanding used to compute net loss per share were 12,189,155 for the year ended December 31, 2014, compared to 729,001 for the year ended December 31, 2013.

Research and Development Expenses

Research and development expenses for the fourth quarter of 2014 were $7.3 million, compared to $2.5 million for the fourth quarter of 2013. Research and development expenses for the year ended December 31, 2014 were $27.4 million, compared to $9.6 million for the year ended December 31, 2013. The increase in research and development expenses for the quarter and year ended December 31, 2014 as compared to prior year periods was primarily due to increased costs associated with the advancement of the Company's beloranib program, ZGN-839 and other early stage development programs (consisting of our second-generation MetAP2 inhibitors). In addition, the increase for the year ended December 31, 2014 as compared to the prior year was a result of $7.0 million in expenses related to milestone payments, primarily to Chong Kun Dang Pharmaceutical Corporation (CKD Pharma), triggered by the initiation of the bestPWS Phase 3 clinical trial which the Company initiated in September 2014.

General and Administrative Expenses

General and administrative expenses for the fourth quarter of 2014 were $3.3 million, compared to $1.2 million for the fourth quarter of 2013. General and administrative expenses for the year ended December 31, 2014 were $8.1 million, compared to $4.2 million for the year ended December 31, 2013. The increase in general and administrative expenses for the quarter and year ended December 31, 2014 as compared to prior year periods was primarily due to increased personnel related costs, increased travel and other related costs, and increased professional fees.

2015 Financial Guidance

The Company expects that its cash and cash equivalents and marketable securities balance will be greater than $145.0 million at December 31, 2015.

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

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.

About Hypothalamic Injury-Associated Obesity (HIAO)

When the hypothalamus, a small area of the brain responsible for many hormonal and metabolic functions including the desire to eat, is injured, a syndrome of intractable weight gain can ensue, resulting in severe obesity and a poor quality of life. This rare and complicated medical condition occurs in affected individuals most commonly due to a benign central nervous system tumor called craniopharyngioma, which presents as a mass in or near the hypothalamus. When the tumor is treated with surgical resection and radiation therapy, the hypothalamus often becomes severely damaged and/or dysfunctional, which can result in loss of appetite control and reduction in metabolic rate. Craniopharyngioma-associated obesity incidence estimates have ranged from 0.13 to 0.17 per 100,000 per year. Other comparably located tumors such as pituitary macroadenoma, medulloblastoma, and pineal germinoma, affect a smaller number of patients, but patients with these tumors can have a similar clinical presentation with respect to obesity. Rarely, this form of obesity also has been reported in cases of head trauma or stroke leading to injury to the hypothalamus.
