Orexigen Therapeutics Reports Corporate and Financial Results for the First Quarter Ended March 31, 2014

SAN DIEGO, May 8, 2014 /PRNewswire/ -- Orexigen^® Therapeutics, Inc. (Nasdaq: OREX), a biopharmaceutical company focused on the treatment of obesity, today announced corporate and financial results for the first quarter ended March 31, 2014.

"With the June 10 PDUFA date for NB32 quickly approaching, we are excited to be working closely with our partner for North America, Takeda Pharmaceuticals, on final preparations to launch NB32, if approved, with a field force of approximately 900 sales representatives focusing on primary care physicians in the United States," said Michael Narachi, CEO of Orexigen.

"Additionally, by the end of this month we will submit responses to the Day 120 List of Questions for our European Marketing Authorization Application, and we continue to anticipate a positive benefit risk assessment at the conclusion of the CHMP's review," Narachi continued. "Interest in NB32 rights outside North America has been catalyzed by availability of Light Study results to support regulatory activities and potential lifecycle development opportunities in diabetes. We continue to make progress toward a rest of world partnership for NB32."

Financial results for the three months ended March 31, 2014
For the three months ended March 31, 2014, Orexigen reported a net loss of $24.9 million, or $0.23 per share, as compared to a net loss of $19.4 million, or $0.21 per share, for the first quarter of 2013.

Total operating expenses for the first quarter of 2014 were $24.0 million compared to $20.3 million for the first quarter of 2013. This overall increase in operating expenses reflects an increase in raw materials, inventory, and manufacturing-related expenses and in salaries and personnel related costs. While Orexigen is responsible for manufacturing NB32, Takeda Pharmaceuticals will reimburse Orexigen for manufacturing related costs, including finished goods.

As of March 31, 2014, Orexigen had $37.6 million in cash and cash equivalents and an additional $117.5 million in marketable securities, for a total of $155.1 million. Orexigen is eligible to receive cash milestone payments of $100 million from Takeda Pharmaceuticals, between US approval and first commercial sale of NB32.

NB32 program update:

• NB32 (32 mg naltrexone sustained-release (SR)/360 mg bupropion SR), an investigational medicine for weight loss and the maintenance of weight loss: In December 2013, Orexigen resubmitted the NB32 New Drug Application to the United States Food and Drug Administration (FDA), which assigned a Prescription Drug User Fee Act goal date of June 10, 2014 for the conclusion of its review. Based on the results of the interim analysis of the Light Study (an ongoing cardiovascular outcomes trial), which Orexigen believes clearly address the single approval deficiency of the January 2011 Complete Response Letter, the Company is highly confident in the U.S. approval of NB32.
  
  In addition to the resubmitted NDA currently being reviewed by FDA, in October 2013 Orexigen submitted a Marketing Authorization Application for NB32 to the European Medicines Agency (EMA). This submission is being reviewed for the first time. Orexigen received the Day 120 List of Questions from the EMA's Committee for Medicinal Products for Human Use (CHMP) and will submit the Company's responses this month. Orexigen is confident that NB32 will receive a positive opinion from the CHMP at the conclusion of its review.
  
  Orexigen has licensed North American NB32 rights to Takeda. Takeda is preparing a well resourced primary care U.S. launch for NB32 with approximately 900 sales representatives.
  
  Orexigen owns NB32 rights outside of North America and will seek a partner to commercialize NB32 in those territories.
