Spectrum Pharmaceuticals Announces Third Quarter 2009 Corporate Update; ZEVALIN® Sales up 80% over Third Quarter 2008

Spectrum Pharmaceuticals, Inc. (NasdaqGM: SPPI), a commercial-stage biotechnology company with a primary focus in oncology, today reported financial results for the third quarter ended September 30, 2009.

"During the quarter, we made significant progress toward stabilizing, and ultimately growing, ZEVALIN^® sales revenue, even before its September 3^rd approval in the first-line setting,” said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. "We believe the sales stabilization in the third quarter is a direct result of our concerted efforts to remove many of the barriers that have hindered ZEVALIN’s use in the hospital and community settings. We continue to remain optimistic about ZEVALIN’s growth prospects, as ZEVALIN has received a Category 1 recommendation from the National Comprehensive Cancer Network^® Drugs and Biologic Compendium™, we have significantly expanded our sales force, ZEVALIN received a label expanding approval in September, and we have made great progress toward a streamlined reimbursement standard for this important therapeutic.”

Third Quarter Results¹ Ended September 30, 2009

Consolidated revenue of $7.1 million was comprised of product sales of $5.0 million – $4.7 million from ZEVALIN and $0.3 million from FUSILEV^® – and $2.1 million attributable to the amortization of the Allergan licensing fee. This compares to no similar revenue in the same period in 2008. The Company recorded a net loss of $8.4 million, or ($0.20) per share, compared to net loss of $8.8 million, or ($0.28) per share, in the third quarter of 2008. Total research and development expenses were $5.5 million, as compared to $6.0 million in the same period of 2008, a $0.5 million, or 8.3% decrease, mainly due to sharing by its partner, Allergan Inc., of apaziquone related development costs, and a reduction in costs related to other pipeline products. Selling, general and administrative expenses were $7.0 million, a $3.9 million increase, compared to the $3.1 million in the same period in 2008, attributable to the direct cost of commercialization activities of ZEVALIN and FUSILEV and related payroll costs.

Nine-Month Results¹ Ended September 30, 2009

Consolidated revenue of $29.4 million was comprised of product sales of $23.0 million – $10.6 million from ZEVALIN and $12.4 million from FUSILEV – and $6.4 million attributable to the amortization of the Allergan licensing fee. This compares to $20.7 million of one-time, non-recurring revenue in the same period of 2008 from the sale of rights to certain non-core products. The Company recorded a net loss of $17.5 million, or ($0.48) per share, compared to a net loss of $6.8 million, or ($0.22) per share, in the same period of 2008. Research and development expenses were $17.5 million, as compared to $19.1 million in the same period of 2008, a $1.6 million, or 8.4% decrease, mainly due to sharing by its partner, Allergan Inc., of apaziquone related development costs, and a reduction in costs related to other pipeline products. Selling, general and administrative expenses were $22.5 million, a $13.6 million increase, compared to the $8.9 million in the same period in 2008, attributable to the commercialization of ZEVALIN and FUSILEV and related payroll costs.

Net cash used in operations in the nine month period ended September 30, 2009 was $7.1 million. The operating cash outflows are primarily attributable to higher selling, general, and administrative expenses, substantially mitigated by revenues from ZEVALIN and FUSILEV and the participation by Allergan Inc. in apaziquone related development expenses.

During the third quarter ended September 30, 2009, the Company sold 6.6 million shares of common stock for $50 million in gross proceeds. As of September 30, 2009, the Company had cash and short term investments of $143 million, compared to $106 million as of June 30, 2009. As of September 30, 2009, the Company had 48.7 million shares issued and outstanding.

About ZEVALIN^® and the ZEVALIN Therapeutic Regimen

ZEVALIN (ibritumomab tiuxetan) is indicated for the treatment of patients with previously untreated follicular non-Hodgkin’s Lymphoma (NHL), who achieve a partial or complete response to first-line chemotherapy. ZEVALIN is also indicated for the treatment of patients with relapsed or refractory, low-grade or follicular B-cell non-Hodgkin's lymphoma.

ZEVALIN is a CD20-directed radiotherapeutic antibody administered as part of the ZEVALIN therapeutic regimen. The ZEVALIN therapeutic regimen consists of three components: rituximab, Indium-111 (In-111) radiolabeled ZEVALIN for imaging, and Yttrium-90 (Y-90) radiolabeled ZEVALIN for therapy. The ZEVALIN therapeutic regimen is a form of cancer therapy called radioimmunotherapy. Radioimmunotherapy (RIT) is an innovative form of cancer treatment with a mechanism of action that is different from traditional chemotherapy. RIT builds on the combined effect of a targeted biologic monoclonal antibody augmented with the therapeutic effects of a beta-emitting radioisotope.

Important ZEVALIN^® Safety Information

Deaths have occurred within 24 hours of rituximab infusion, an essential component of the ZEVALIN therapeutic regimen. These fatalities were associated with hypoxia, pulmonary infiltrates, acute respiratory distress syndrome, myocardial infarction, ventricular fibrillation, or cardiogenic shock. Most (80%) fatalities occurred with the first rituximab infusion. ZEVALIN administration results in severe and prolonged cytopenias in most patients. Severe cutaneous and mucocutaneous reactions, some fatal, can occur with the ZEVALIN therapeutic regimen.

Please see full Prescribing Information, including Boxed WARNINGS, for ZEVALIN and rituximab.

About FUSILEV™ (levoleucovorin) for Injection

FUSILEV™, a novel folate analog, is available in 50-mg vials of freeze-dried powder. FUSILEV rescue is indicated after high-dose methotrexate therapy in osteosarcoma. FUSILEV is also indicated to diminish the toxicity and counteract the effects of impaired methotrexate elimination and of inadvertent overdosage of folic acid antagonists. FUSILEV (levoleucovorin or (6S)-leucovorin) is the only commercially available formulation containing only the pharmacologically active isomer of leucovorin.
