Data Presented In Oral Sessions At The 52nd Annual Meeting Of The American Society Of Hematology
ORLANDO, FL, USA | December 7, 2010 | Spectrum Pharmaceuticals, Inc. (NasdaqGM: SPPI) today announced the presentation of ZEVALIN data as a preparatory or conditioning regimen prior to both allogeneic and autologous stem cell transplantation at the 52nd American Society of Hematology (ASH) Annual Meeting in Orlando, Florida.
“These presentations confirm our belief that ZEVALIN will continue to show strong data in a range of protocols to prepare lymphoma patients for these life-saving procedures.”
Prior to stem cell transplantation to a patient, the existing disease must be eradicated. Therefore, patients undergo conditioning regimens to eliminate, in the case of blood cancers, all or most of the tumor cells. This also destroys the patient’s blood generating (hematopoietic) system. Following conditioning, stem cells either derived from the patient’s own system (autologous) or from a matched donor (allogeneic) are introduced to the patient to renew the hematopoietic system.
“These data solidify the role of ZEVALIN in treatment regimens for lymphoma patients,” said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals, Inc. “These presentations confirm our belief that ZEVALIN will continue to show strong data in a range of protocols to prepare lymphoma patients for these life-saving procedures.”
Ajay K. Gopal, MD, Assistant Professor of Medical Oncology at the University of Washington School of Medicine and an Assistant Member of the Clinical Research Division of the Fred Hutchinson Cancer Research Center, presented data on the use of ZEVALIN, Fludarabine, and TBI based Non-Myeloablative Allogenic Transplant Conditioning for High-Risk B-Cell lymphomas (n=40). Non-myeloablative allogeneic transplantation (NMAT) can provide prolonged remissions in patients with advanced B-cell lymphoma via the graft versus lymphoma effect, though patients and donors need to be carefully selected. Dr. Gopal’s data indicated that use of ZEVALIN in NMAT is safe and feasible, and can lead to early objective responses and prolonged disease control in a subset of patients.
Dr. Gopal’s ASH presentation is entitled Y-90 Ibritumomab Tiuxetan, Fludarabine, and TBI Based Non-Myeloablative Allogeneic Transplant Conditioning for High-Risk B-Cell Lymphoma. ASH Abstract #33.
Avichai Shimoni, MD, from the Chaim Sheba Medical Center in Tel-Hashomer, Israel, presented data from a multicenter Phase 2 study of ZEVALIN as part of a transplantation preparatory regimen for patients with aggressive lymphomas. In randomized study (n=43), a rarity in the field of transplantation, a regimen including a standard dose of ZEVALIN (Z-BEAM) was compared with a commonly used regimen (BEAM) in the conditioning of patients prior to autologous stem cell transplantation (ASCT). High-dose chemotherapy and ASCT is a standard therapy for patients with refractory/recurrent aggressive lymphoma, who are still chemotherapy-sensitive after second-line therapy. Dr. Shimoni’s data indicated that the addition of ZEVALIN (Z-BEAM) was feasible and added no toxicity incremental to what was observed on BEAM. In multi-variate risk-adjusted analysis (Cox Model), the benefit on progression-free survival (PFS) of adding ZEVALIN to BEAM was found to be significant (P=0.03). The benefit was most pronounced in patients with low-risk disease, who had a 2-year PFS of 89% in the Z-BEAM group compared to 44% in the BEAM group.
Dr. Shimoni’s ASH presentation is entitled A Multi-Center Prospective Randomized Study Comparing Ibritumomab Tiuxetan (ZEVALIN) and High-Dose BEAM Chemotherapy (Z-BEAM) vs. BEAM Alone as the Conditioning Regimen Prior to Autologous Stem-Cell Transplantation in Patients with Aggressive Lymphoma: Possible Advantage for Z-BEAM in Low-Risk Patients. ASH Abstract #686.
Amrita Krishan, MD, Director of City of Hope National Medical Center’s Multiple Myeloma Program, presented a retrospective analysis designed to compare outcomes for 92 patients with diffuse large B-cell lymphoma (DLBCL) who received stem cell transplants after conditioning with either total body irradiation (TBI) or ZEVALIN (Z-BEAM). The data demonstrated a trend toward improved progression-free survival (PFS) in the Z-BEAM cohort with a toxicity profile similar to high dose BEAM. Two-year PFS for the Z-BEAM group was 66% compared to 50% for the TBI group. Four years following stem cell transplant, patients treated with Z-BEAM demonstrated a 20% improvement in PFS compared to TBI patients.
Dr. Krishan’s presentation is entitled Comparative Analysis of Autologous Hematopoietic Cell Transplantation with Radioimmunotherapy (RIT) Based Conditioning Versus Total Body Irradiation (TBI) for High-Risk Diffuse Large Cell Lymphoma (DLCL): Toxicity and Efficacy. ASH Abstract #32.
About ZEVALIN® and the ZEVALIN Therapeutic Regimen
ZEVALIN (ibritumomab tiuxetan) injection for intravenous use 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. 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(R) 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 Non-Hodgkin’s Lymphoma
Non-Hodgkin’s lymphoma (NHL) is caused by the abnormal proliferation of white blood cells and 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. Follicular lymphoma is a type of indolent lymphoma. According to the National Cancer Institute’s SEER database (http://seer.cancer.gov/statfacts/html/nhl.html) there were approximately 419,533 patients alive with a history of NHL. According to the American Cancer Society, NHL is one of the most common cancers in the United States, accounting for approximately 4% of all cancers. In 2010, an estimated 65,540 people will be diagnosed and approximately 20,210 people will die from the disease.
