Orexigen Therapeutics Enters Into Agreement with Sanofi to Manufacture Contrave for Territories Outside North America

SAN DIEGO, Nov. 6, 2013 /PRNewswire/ -- Orexigen® Therapeutics, Inc. (Nasdaq: OREX), a biopharmaceutical company focused on the treatment of obesity, today announced that it has entered into a commercial supply agreement with Sanofi to act as Orexigen's contract manufacturer for Contrave® (32 mg naltrexone sustained release (SR) / 360 mg bupropion SR) for territories outside North America.  Sanofi will manufacture Contrave tablets at one of several facilities in France.

"We are pleased to engage a manufacturer with Sanofi's scale and expertise," said Michael Narachi, CEO of Orexigen. "This agreement expands and diversifies our existing commercial supply network and will help ensure we will be ready to supply Contrave globally if approved."

About Contrave
Orexigen is evaluating Contrave for the management of obesity, including weight loss and maintenance of weight loss, in conjunction with lifestyle modification, and is currently conducting the Light Study, a cardiovascular outcomes trial. The primary objective of the double‐blind, randomized, placebo‐controlled clinical trial, which Orexigen is conducting under a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA), is to rule out excess cardiovascular risk in overweight and obese patients receiving Contrave. An interim analysis of the Light Study is anticipated by early December, enabling the potential resubmission of the Contrave New Drug Application (NDA) to the FDA by year end.

In October Orexigen submitted a Marketing Authorization Application (MAA) for Contrave to the European Medicines Agency (EMA).

Orexigen has licensed North American Contrave commercial rights to Takeda Pharmaceuticals. Orexigen owns Contrave rights in Europe and throughout the rest of the world outside of North America and will seek a partner to commercialize Contrave in those territories.

Forward‐Looking Statements
Orexigen cautions you that statements included in this press release that are not a description of historical facts are forward‐looking statements. Words such as "believes," "anticipates," "plans," "expects," "indicates," "will," "should," "intends," "potential," "suggests," "assuming," "designed" and similar expressions are intended to identify forward‐looking statements. These statements are based on the company's current beliefs and expectations. These forward‐looking statements include statements regarding: the potential for, and timing of, the interim analysis and resubmission of a Contrave NDA; the potential for, and timing of, the accrual and adjudication of major adverse cardiovascular events (MACE); the probability of success of the Light Study; the possibility of resubmitting the Contrave NDA with the independent Data Monitoring Committee report on the interim analysis and without the clinical study report for the interim analysis; the potential for, and timing of, approval in the U.S.; the potential for, and timing of MAA approval by the EMA; the potential to have cardiovascular outcomes data from the Light Study available for the CHMP Day 120 List of Questions; the safety and effectiveness of Contrave; the potential for past Contrave clinical trials to predict the outcome of future Contrave clinical trials; the potential for the FDA to honor the SPA and the protocol for the Contrave® cardiovascular outcomes trial, or Light Study; and the potential to license commercial rights to Contrave outside North America. The inclusion of forward‐looking statements should not be regarded as a representation by Orexigen that any of its plans will be achieved. Actual results may differ materially from those expressed or implied in this release due to the risk and uncertainties inherent in the Orexigen business, including, without limitation: the possibility that the FDA determines not to initiate review of the Contrave NDA until it has received the complete study report for the interim analysis; the SPA is not binding on the FDA if public health concerns unrecognized at the time the SPA agreement was entered into become evident, other new scientific concerns regarding product safety or efficacy arise, or if Orexigen fails to comply with the agreed upon trial protocol; Orexigen's ability to conduct the Light Study and the progress and timing thereof, including risks associated with retaining the appropriate patients in the Light Study; Orexigen's ability to demonstrate in the Light Study that the risk of MACE in overweight and obese patients treated with Contrave does not adversely affect Contrave's benefit‐risk profile; the potential that earlier clinical trials may not be predictive of future results in the Light Study; the potential for the FDA to not approve Contrave even after the resubmission with the MACE data; the potential for early termination of Orexigen's North American collaboration agreement with Takeda Pharmaceutical Company Limited; the costs and time required to complete additional clinical, non‐clinical or other requirements prior to any resubmission of the Contrave NDA; the therapeutic and commercial value of Contrave; Orexigen's ability to maintain sufficient capital to fund our operations through potential approval of Contrave in 2014; Orexigen's ability to enter into a collaborative partnership for Contrave outside North America on acceptable terms, if at all; and other risks described in Orexigen's filings with the Securities and Exchange Commission. You are cautioned not to place undue reliance on these forward‐looking statements, which speak only as of the date hereof, and Orexigen undertakes no obligation to revise or update this news release to reflect events or circumstances after the date hereof. Further information regarding these and other risks is included under the heading "Risk Factors" in Orexigen's Quarterly Report on Form 10‐Q filed with the Securities and Exchange Commission August 7, 2013 and its other reports, which are available from the SEC's website (www.sec.gov) and on Orexigen's website (www.orexigen.com) under the heading "Investor Relations."
