2008 ZEVALIN Sales Were Approximately $11.4 Million

Spectrum Will Book 100% of ZEVALIN Sales Moving Forward

PDUFA Action Date for ZEVALIN in First-Line Use is July 2, 2009

Multiple Synergies Anticipated With FUSILEV(TM)


IRVINE, Calif.--(HSMN NewsFeed)--Spectrum Pharmaceuticals (NasdaqGM:SPPI ) announced today the closing of the transaction whereby Spectrum Pharmaceuticals acquired 100% control of RIT Oncology, LLC™, to commercialize ZEVALIN® ([90Y]-ibritumomab tiuxetan) in the United States. In connection with the closing, Spectrum Pharmaceuticals will pay its former partner a total of $16.5 million, which is subject to further adjustments based on outstanding liabilities and obligations. Additionally, there will be no further payments or milestones to the former partner. Spectrum Pharmaceuticals now has 100% ownership of RIT Oncology, LLC, and will be responsible for all activities relating to ZEVALIN. Spectrum Pharmaceuticals will now book 100% of ZEVALIN revenues.

ZEVALIN is currently approved for the treatment of patients with relapsed or refractory, low-grade or follicular B-cell non-Hodgkin's lymphoma (NHL), including patients who have rituximab-refractory follicular NHL. ZEVALIN is under review by the FDA for use as a first line consolidation therapy for patients with NHL. The FDA recently established July 2, 2009 as a target date for a decision regarding the ZEVALIN sBLA.

“We are excited to have 100% ownership of ZEVALIN,” said Rajesh C. Shrotriya, M.D., Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. “Recent clinical data have dramatically underscored the clinical benefits of ZEVALIN in NHL. We believe that approval of the supplemental Biologics License Application (sBLA) for first-line consolidation therapy, which is based on the Phase 3 FIT data, anticipated regulatory and reimbursement changes, combined with our marketing efforts, will substantially improve patient access to ZEVALIN.”

“The anticipated FDA approval of the sBLA for ZEVALIN on or before the July 2, 2009 PDUFA action date will allow for the label to address a substantially larger patient population,” added Dr. Shrotriya. “We expect our commercial launch program to be fully in place by the anticipated approval of the additional indication for ZEVALIN in July. This asset, along with FUSILEV™, creates added synergies across multiple cost centers, thereby maximizing the return on our investments.”

On November 28, 2008, the FDA accepted for filing and review, and granted priority review status for, the supplemental Biologics License Application for use of ZEVALIN as a first line consolidation therapy for patients with NHL. Priority review is granted by the FDA for a treatment that addresses a significant unmet medical need. This does not represent any evaluation of the adequacy of the data submitted. A Prescription Drug User Fee Act (PDUFA) target date of July 2, 2009 has been established by the FDA for a decision regarding the ZEVALIN sBLA.

If approved, ZEVALIN would be the first therapeutic available to patients as first-line consolidation therapy to treat NHL. Following the anticipated approval, the addressable patient population would increase by approximately 18,000. Together with ZEVALIN's current approval as treatment for patients with relapsed or refractory, low-grade or follicular B-cell NHL, including patients that are rituximab-refractory or rituximab-naive, approval of ZEVALIN as first-line consolidation therapy may allow ZEVALIN to be used in several lines of NHL therapy.

About RIT Oncology, LLC

Spectrum Pharmaceuticals is the sole member of the LLC, whose sole purpose is to commercialize ZEVALIN in the United States.

About ZEVALIN®

ZEVALIN® (Ibritumomab Tiuxetan) is a form of cancer therapy called radioimmunotherapy and is indicated as part of the ZEVALIN therapeutic regimen for treatment of relapsed or refractory, low-grade or follicular B-cell NHL, including patients with rituximab-refractory follicular NHL. ZEVALIN is also indicated, under accelerated approval, for the treatment of relapsed or refractory, rituximab-naïve, low-grade and follicular NHL based on studies using a surrogate endpoint of overall response rate. It was approved by the FDA in February of 2002 as the first radioimmunotherapeutic agent for the treatment of NHL.

Rare deaths associated with an infusion reaction symptom complex have occurred within 24 hours of rituximab (Rituxan®) infusions. Yttrium-90 ZEVALIN administration results in severe and prolonged cytopenias in most patients. Severe cutaneous and mucocutaneous reactions have been reported. The most serious adverse reactions of the ZEVALIN therapeutic regimen were primarily hematologic, including neutropenia, thrombocytopenia and anemia. Infusion-related toxicities were associated with pre-administration of rituximab. The risk of hematologic toxicity correlated with the degree of bone marrow involvement prior to ZEVALIN therapy. Myelodysplasia or acute myelogenous leukemia was observed in 2 percent of patients (8 to 34 months after treatment). ZEVALIN should only be used by health care professionals qualified by training and experience in the safe use of radionuclides.

About Non-Hodgkin’s Lymphoma

Non-Hodgkin’s lymphoma (NHL) is caused by the abnormal proliferation of white blood cells and normally spreads through the lymphatic system, a system of vessels that drains fluid from the body. NHL can be broadly classified into two main forms – aggressive NHL, a rapidly spreading acute form of the disease, and indolent NHL, which progresses more slowly. According to the National Cancer Institute’s SEER database there were nearly 400,000 people in the U.S. with NHL in 2004. The American Cancer Society estimates that in the United States 66,120 people are expected to be diagnosed with NHL in 2008. Additionally, approximately 19,160 are expected to die from this disease in 2008.

About First-Line Consolidation Therapy

Consolidation therapy aims to rapidly improve the quality of the response achieved with initial remission induction treatment. Induction therapy is a treatment designed as a first step toward reducing the number of cancer cells.

About the Phase 3 First-line Indolent Trial (FIT)

The multinational, randomized Phase 3 First-line Indolent Trial (FIT) evaluated the benefit and safety of a single infusion of ZEVALIN in 414 patients with CD20-positive follicular NHL who had achieved a partial response or a complete response after receiving one of the standard first-line chemotherapy regimens. The FIT trial demonstrated that when used as a first-line consolidation therapy for patients with follicular NHL, ZEVALIN significantly improved the median progression-free survival time from 13 months (control arm) to 37 months (ZEVALIN arm) (p<0.0001). The FIT trial results were presented for the first time in one oral and three poster presentations at the American Society of Hematology (ASH) conference in December 2007.

The primary investigators of the study concluded that ZEVALIN consolidation of first remission in advanced stage follicular NHL is highly effective, resulting in a total complete response (CR + CRu) rate of 87 percent and prolongation of median progression-free survival (PFS) by approximately two years, with a toxicity profile comparable to that seen with ZEVALIN’s use in approved indications. ZEVALIN-treated patients had reversible Grade 3 or 4 hematologic side effects including neutropenia in 67 percent, thrombocytopenia in 61 percent, and anemia in 3 percent of patients. Non-hematologic toxicities were 24 percent Grade 3, 5 percent Grade 4, and Grade 3/4 infection was 8 percent.
