Orexigen Therapeutics, Inc. Announces Fourth Quarter and Year Ended December 31, 2008 Financial Results

SAN DIEGO, March 12 /PRNewswire-FirstCall/ -- Orexigen(R) Therapeutics, Inc. , a biopharmaceutical company focused on the treatment of obesity, today announced financial results for the three months and year ended December 31, 2008.

Three months ended December 31, 2008

As of December 31, 2008, Orexigen held $45.5 million in cash and cash equivalents and an additional $40.7 million in investment securities, available-for-sale.

For the three months ended December 31, 2008, Orexigen reported a net loss of $22.1 million, or $0.64 per share attributable to common stockholders, as compared to a net loss of $19.4 million, or $0.72 per share attributable to common stockholders, for the same period in 2007.

Total operating expenses for the three months ended December 31, 2008 were $22.1 million compared to $20.3 million for the same period in 2007. The increased operating expenses were due primarily to an increase in general and administrative expenses of $1.3 million due to increases in non-cash stock-based compensation expense, salaries and personnel related costs, facilities expenses and consulting activities.

Year ended December 31, 2008

For the year ended December 31, 2008, Orexigen reported a net loss of $93.2 million, or $2.76 per share attributable to common stockholders, as compared to a net loss of $57.8 million, or $3.08 per share attributable to common stockholders, for 2007.

Total operating expenses for the year ended December 31, 2008 were $94.9 million compared to $60.9 million for 2007. The increased operating expenses were due primarily to a $29.0 million increase in research and development expenses in connection with the Company's Contrave(R) Phase 3 clinical trials, related proprietary product formulation work and increased consulting activities. In addition, general and administrative expenses increased by $5.0 million due primarily to increases in non-cash stock-based compensation expense, salaries and personnel related costs, facilities expenses and consulting activities.

"Orexigen has made significant progress in the past year," said Eckard Weber, M.D., Interim President and CEO of Orexigen. "We executed a successful equity financing, completed enrollment in our four Phase 3 clinical trials for Contrave and recently disclosed what we believe are promising results in the first of our four Contrave Phase 3 clinical trials. In addition, we were issued two key patents by the U.S. Patent and Trademark Office, which we believe will extend protection for Contrave through at least 2024."
