IRVINE, California — August 9, 2007 — Spectrum Pharmaceuticals, Inc. (NASDAQ: SPPI) today reported financial results for the second quarter ended June 30, 2007.

The Company incurred a second quarter of 2007 net loss of approximately $6.3 million, or ($0.22) per share, compared to a net loss of approximately $9.0 million, or ($0.37) per share in the second quarter of 2006. Revenue in the second quarter of 2007 included a $4 million milestone payment received from GPC Biotech, and compared to no revenues in the second quarter of 2006. Research and development expenses were approximately $7.2 million in the second quarter 2007, compared to approximately $4 million in the second quarter of 2006, due to the expanded scope of the Company’s clinical development activities. General and administrative expenses were approximately $3.0 million in the second quarter of 2007, compared to approximately $1.5 million in the second quarter 2006, primarily due to legal expenses resulting from the arbitration we initiated against GPC Biotech. As of August 3, 2007, approximately 31.1 million shares were issued and outstanding.

On May 11, 2007, the Company raised approximately $30 million through the issuance of common stock at a price of $6.25 per share. No warrants were issued in this offering. During the six-month period ended June 30, 2007, net cash used in operations was approximately $10.3 million. As of June 30, 2007, the Company had cash, cash equivalents, and marketable securities on hand of approximately $71 million, compared to $50.6 million as of December 31, 2006.

“We recently achieved several milestones, including filing an IND for SPI-1620, a novel chemotherapy targeting agent; filing an NDA amendment for ISO-Vorin; and adding to our portfolio by in-licensing ortataxel, a promising third generation taxane with clinical data in more than 350 patients,” stated Rajesh C. Shrotriya, M.D., Chairman, President and Chief Executive Officer of Spectrum Pharmaceuticals. “These advancements, along with progress we continue to make with the ongoing Phase 3 pivotal trial for EOquin^® for non-invasive bladder cancer, and evaluation of patients in our Phase 2b trial of ozarelix in benign prostate hypertrophy, represent our team’s ability to identify diverse, promising drug candidates and move them through development with the goal of bringing new treatments to patients as efficiently as possible.”
