FDA Approves ZEVALIN(R) Expanded Label as Part of First-Line Therapy in Treatment of Follicular Non-Hodgkin's Lymphoma
IRVINE, Calif., Sep 04, 2009 (BUSINESS WIRE) -- Spectrum Pharmaceuticals (NasdaqGM:SPPI), a commercial-stage biotechnology company with a focus in oncology, today announced ZEVALIN(R) (ibritumomab tiuxetan), a CD20-directed radiotherapeutic antibody, received approval from the U.S. Food and Drug Administration (FDA) for an expanded label 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. This new and expanded indication supplements the 2002 FDA approval of ZEVALIN as treatment for patients with relapsed or refractory, low-grade or follicular B-cell non-Hodgkin's lymphoma.
"We believe the approval of ZEVALIN as an effective treatment option following a first-line regimen represents a notable advance in the treatment of non-Hodgkin's Lymphoma, and significantly expands the addressable population for ZEVALIN," said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. "We are confident that the strategic and tactical initiatives we have implemented will overcome the clinical, logistical, and reimbursement challenges that have previously hindered physician and patient access to ZEVALIN."
The approval of the new indication was based on data from the FIT Study (First-line Indolent Therapy). The multicenter, randomized, open-label Phase 3 study evaluated the safety and efficacy of ZEVALIN in 414 patients with CD20-positive follicular NHL who had achieved a partial response or a complete response after receiving a first-line chemotherapy regimen. Patients were treated with one of the following first-line chemotherapy regimens: chlorambucil, fludarabine, fludarabine-containing regimen, CVP/COP, CHOP, CHOP-like, or rituximab-containing chemotherapy. At 3.5 years of follow-up, the FIT trial demonstrated that when used as part of first-line chemotherapy for patients with follicular NHL, ZEVALIN significantly improved the median progression-free survival time from 18 months (control arm) to 38 months (ZEVALIN arm) (p<0.0001).
|Median PFS||38 months||18 months|
Updated results with an additional year of follow up were presented at the American Society of Hematology 2008 Annual Meeting. The safety profile of ZEVALIN was consistent with previous clinical studies, with hematologic toxicity as the most common adverse reaction in the FIT study.
"Our institution is one of the leading cancer research centers in the United States investigating the clinical utility of ZEVALIN in NHL therapy," said Stephanie A. Gregory, MD, The Elodia Kehm Chair of Hematology, Professor of Medicine, and Director, Section of Hematology at Rush University Medical Center. "We believe that the approval of ZEVALIN as part of first-line chemotherapy represents an important advance in the treatment of patients with NHL."
The National Comprehensive Cancer Network (NCCN) Drugs and Biologics Compendium currently lists chemotherapy followed by radioimmunotherapy, such as ZEVALIN, for patients with follicular NHL with a Category 1 recommendation. The Centers for Medicare & Medicaid Services (CMS) announced in June 2008 that it would recognize the NCCN Drugs & Biologics Compendium as a source of information to determine which drugs may be covered under Medicare Part B.
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.

About ZEVALIN(R) and the ZEVALIN Therapeutic Regimen
ZEVALIN (ibritumomab tiuxetan) 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.

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. The incidence of NHL (all types including Follicular and Aggressive) is projected to be 65,980 in 2009 and that 19,500 patients are expected to die from this disease in the United States in 2009.
The National Comprehensive Cancer Network (NCCN), a not-for-profit alliance of 21 of the world's leading cancer centers, is dedicated to improving the quality and effectiveness of care provided to patients with cancer.
