STEVENSON, Md.--(BUSINESS WIRE)--

The securities litigation law firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been commenced in the United States District Court for the Southern District of California on behalf of purchasers of Orexigen Therapeutics, Inc. ("Orexigen" or the "Company") (Nasdaq: OREX) securities during the period between March 3, 2015 and March 5, 2015, inclusive (the "Class Period"). Investors who wish to become proactively involved in the litigation have until May 11, 2015 to seek appointment as lead plaintiff.

If you have suffered a loss from investment in Orexigen securities purchased on or after March 3, 2015 and held through the revelation of negative information during and/or at the end of the Class Period, as described below, and would like to learn more about this lawsuit and your ability to participate as a lead plaintiff, without cost or obligation to you, please visit our website at http://www.browerpiven.com/currentsecuritiescases.html. You may also request more information by contacting Brower Piven either by email at [email protected] or by telephone at (410) 415-6616. No class has yet been certified in the above action. Members of the Class will be represented by the lead plaintiff and counsel chosen by the lead plaintiff.

If you wish to choose counsel to represent you and the Class, you must apply to be appointed lead plaintiff and be selected by the Court. The lead plaintiff will direct the litigation and participate in important decisions including whether to accept a settlement for the Class in the action. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in Company securities during the Class Period. Brower Piven also encourages anyone with information regarding the Company's conduct during the period in question to contact the firm, including whistleblowers, former employees, shareholders and others.

The complaint accuses the defendants of violations of the Securities Exchange Act of 1934 by virtue of the defendants' failure to disclose during the Class Period that its statement that a patient group taking Contrave had fewer serious cardiovascular problems than those who took a placebo was unreliable, misleading, and likely false.

According to the complaint, following a Forbes report that the FDA's director of the Office of New Drugs criticized Orexigen's released data and stated that the Company could face fines, civil penalties, or even the withdrawal of Contrave from the market, the value of Orexigen shares declined significantly.

Attorneys at Brower Piven have extensive experience in litigating securities and other class action cases and have been advocating for the rights of shareholders since the 1980s. If you choose to retain counsel, you may retain Brower Piven without financial obligation or cost to you, or you may retain other counsel of your choice. You need take no action at this time to be a member of the class.
