HENDERSON, Nev.--()--Spectrum Pharmaceuticals (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in hematology and oncology, today announced key presentations of clinical and scientific data at the 54th Annual Meeting of the American Society of Hematology (ASH), being held in Atlanta, Georgia, from December 8-11, 2012. The presentations include two oral presentations and 10 poster presentations for ZEVALIN® (ibritumomab tiuxetan) injection for intravenous use, three poster presentations for FOLOTYN® (pralatrexate injection), and four poster presentations for belinostat, a novel histone deacetylase (HDAC) inhibitor.

“Nearly 20 presentations at ASH will feature clinical and scientific data for Spectrum’s commercial products, ZEVALIN and FOLOTYN, as well as our late-stage drug candidate, belinostat,” said Rajesh C. Shrotriya, M.D., Chairman, President and Chief Executive Officer of Spectrum Pharmaceuticals, Inc. “The ZEVALIN-related abstracts demonstrate its use in a multitude of diverse settings and potential indications in which this product is being tested, including transplantation, its use in elderly patients, in frontline treatment and in the treatment of relapsed/refractory disease, as well as in new drug combinations. The FOLOTYN-related abstracts include presentations on new, synergistic combinations with other approved agents and in difficult-to-treat indications, such as HTLV-1-induced leukemia/lymphoma, while belinostat-related presentations are studying new combinations and indications, such as in refractory AML/MDS, as well as research on this promising drug candidate’s mechanism of action.”

About Non-Hodgkin's Lymphoma

According to the National Cancer Institute (www.cancer.gov), there are expected to be 70,130 new cases of non-Hodgkin's lymphoma diagnosed and approximately 18,940 deaths in the United States in 2012. Non-Hodgkin's lymphoma is defined as any of a large group of cancers of lymphocytes (white blood cells). Non-Hodgkin's lymphomas can occur at any age and are often marked by lymph nodes that are larger than normal, fever, and weight loss. There are many different types of non-Hodgkin's lymphoma. These types can be divided into aggressive (fast-growing) and indolent or low grade (slow-growing) types, and they can be formed from either B-cells or T-cells. Prognosis and treatment depend on the stage and type of disease.

About ZEVALIN® and the ZEVALIN Therapeutic Regimen

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

ZEVALIN is a CD20-directed radiotherapeutic antibody. The ZEVALIN therapeutic regimen consists of two components: rituximab, and Yttrium-90 (Y-90) radiolabeled ZEVALIN for therapy. ZEVALIN 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 can result 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. Full prescribing information for ZEVALIN can be found at www.ZEVALIN.com.

About FOLOTYN®

FOLOTYN, (pralatrexate injection), a folate analogue metabolic inhibitor, was discovered by Memorial Sloan-Kettering Cancer Center, SRI International and Southern Research Institute and developed by Allos Therapeutics. In September 2009, the U.S. Food and Drug Administration (FDA) granted accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory PTCL. This indication is based on overall response rate. Clinical benefit such as improvement in progression-free survival or overall survival has not been demonstrated. FOLOTYN has been available to patients in the U.S. since October 2009. An updated analysis of data from PROPEL, the pivotal study of FOLOTYN in patients with relapsed or refractory PTCL, was published in the March 20, 2011 issue of the Journal of Clinical Oncology. FOLOTYN has patent protection through July 2022, based on a five-year patent term extension through the Hatch-Waxman Act. Please see full Prescribing Information for FOLOTYN at www.FOLOTYN.com.

Important FOLOTYN® Safety Information

Warnings and Precautions

FOLOTYN may suppress bone marrow function, manifested by thrombocytopenia, neutropenia, and anemia. Monitor blood counts and omit or modify dose for hematologic toxicities.

Mucositis may occur. If greater-than or equal to Grade 2 mucositis is observed, omit or modify dose. Patients should be instructed to take folic acid and receive vitamin B12 to potentially reduce treatment-related hematological toxicity and mucositis.

Fatal dermatologic reactions may occur. Dermatologic reactions may be progressive and increase in severity with further treatment. Patients with dermatologic reactions should be monitored closely, and if severe, FOLOTYN should be withheld or discontinued. Tumor lysis syndrome may occur. Monitor patients and treat if needed.

FOLOTYN can cause fetal harm. Women should avoid becoming pregnant while being treated with FOLOTYN and pregnant women should be informed of the potential harm to the fetus.

Use caution and monitor patients when administering FOLOTYN to patients with moderate to severe renal function impairment.

Elevated liver function test abnormalities may occur and require monitoring. If liver function test abnormalities are greater-than or equal to Grade 3, omit or modify dose.

Adverse Reactions

The most common adverse reactions were mucositis (70%), thrombocytopenia (41%), nausea (40%), and fatigue (36%). The most common serious adverse events are pyrexia, mucositis, sepsis, febrile neutropenia, dehydration, dyspnea, and thrombocytopenia.

Use in Specific Patient Population

Nursing mothers should be advised to discontinue nursing or the drug, taking into consideration the importance of the drug to the mother.

Drug Interactions

Co-administration of drugs subject to renal clearance (e.g., probenecid, NSAIDs, and trimethoprim/sulfamethoxazole) may result in delayed renal clearance.

Please see FOLOTYN® Full Prescribing Information at www.FOLOTYN.com.

About Belinostat

Belinostat is a Class I and II HDAC inhibitor being studied in multiple clinical trials as a single agent or in combination with chemotherapeutic agents for the treatment of various hematological and solid cancers. Its anticancer effect is thought to be mediated through multiple mechanisms of action, including the inhibition of cell proliferation, induction of apoptosis (programmed cell death), inhibition of angiogenesis, induction of differentiation, and the resensitization of cells that have become resistant to anticancer agents such as platinums, taxanes and topoisomerase II inhibitors. Belinostat is the only HDAC inhibitor in clinical development with multiple potential routes of administration, including short and continuous intravenous infusion; and oral administration.

Conducted under a Special Protocol Assessment (SPA) agreement with the U.S. Food and Drug Administration (FDA), Spectrum’s pivotal, registrational Phase 2 BELIEF trial is evaluating intravenous belinostat as monotherapy for relapsed or refractory peripheral T-cell lymphoma (PTCL), an indication for which this drug candidate has been granted Orphan Drug and Fast Track designations by the FDA. The BELIEF trial is an open-label, multicenter, single arm efficacy and safety study in patients with relapsed or refractory PTCL, who have failed at least one prior systemic therapy. The primary endpoint of the trial is centrally reviewed objective overall response rate (ORR). The trial included approximately 100 clinical centers globally, with completion of patient enrollment announced in September 2011.
