- There is a substantial need for better treatments for DLBCL, which has low survival rates at five years; there are an estimated 20,000 new cases of DLBCL in the U.S. each year
- The ZEST study follows multiple Phase 2 clinical trials supporting advancement of ZEVALIN into a registrational-quality study in aggressive lymphoma; results from the largest of the studies, presented at the 2012 European Hematology Association annual meeting, showed an 84% 5-year overall survival (OS) rate and 75% 5-year progression-free survival (PFS) in older patients with stage II-IV DLBCL who received ZEVALIN following R-CHOP
- The ZEST (Zevalin Evaluation as Sequential Therapy) study will compare the ZEVALIN therapeutic regimen to observation in patients with newly diagnosed stage II, III, or IV DLBCL who are 60 years of age and older and who are in complete remission after first-line R-CHOP or R-CHOP like chemotherapy for their disease
- Primary endpoint is overall survival; secondary endpoints include 2-year OS rate and PFS
Additional ZEVALIN clinical studies in aggressive lymphoma include the SPINOZA (Study with Preparatory INduction Of Zevalin in Aggressive lymphoma) trial, which to date has randomized 39 patients receiving autologous stem cell transplantation (ASCT) for relapsed DLBCL
HENDERSON, NV, USA I September 19, 2012 I Spectrum Pharmaceuticals, Inc. (SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in oncology and hematology, today announced initiation of patient enrollment in the Company’s randomized Phase 3 ZEST (Zevalin Evaluation as Sequential Therapy) trial of ZEVALIN® (ibritumomab tiuxetan) Injection for intravenous use for first-line consolidation in patients with diffuse large B-cell lymphoma (DLBCL) who achieved remission following R-CHOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). The study will assess overall survival (OS) and progression-free survival (PFS) in patients 60 years and older. Patients will consist of newly diagnosed Stage II – IV DLBCL patients with a complete response after the standard six courses of R-CHOP. They will be randomized between observation and ZEVALIN treatment.
“Initiation of the ZEST trial, together with our commitment to the ongoing SPINOZA trial in patients with relapsed DLBCL who receive autologous stem cell transplantation, represent a comprehensive clinical program to determine the full potential of ZEVALIN in DLBCL, the most common form of non-Hodgkin’s lymphoma in which there is substantial unmet need, especially in older patients,” stated Rajesh C. Shrotriya, M.D., Chairman, President and Chief Executive Officer of Spectrum Pharmaceuticals, Inc.
Dr. Shrotriya continued, “Spectrum has a number of near-term and long-term clinical milestones for ZEVALIN, including presentations at major medical meetings, both internationally and in the US, such as at ASH and ASCO. In addition, a patient initiative launched earlier this year and the acquisition of marketing rights in the EU should have a strong impact on increasing awareness of the value of this important product for the global lymphoma community.”
Paul Hamlin, M.D., of the Lymphoma Service at Memorial Sloan-Kettering Cancer Center and a lead investigator in the study, commented, “There is a substantial need for better treatments for DLBCL, particularly in the ever-increasing group of older patients who have fewer treatment options than younger patients. A consolidative therapy that is administered in just one week and improves survival would have a huge impact on lymphoma patients’ lives. The very encouraging evidence from earlier Phase 2 studies of ZEVALIN in aggressive lymphomas, both in terms of safety and efficacy results, form the basis for the randomized study, and ZEVALIN has the potential to expand our arsenal against this terrible disease.”
Promising results of the largest of the Phase 2 studies were presented at this year’s annual meeting of the European Hematology Association (EHA). The data demonstrated that ZEVALIN therapeutic regimen following R-CHOP treatment resulted in a 5-year overall survival rate of 84% and 5-year progression-free survival of 75% in 44 older patients (age 62-86) with stage II-IV DLBCL. Overall survival was improved approximately 15% over that observed in similar risk patients treated with R-CHOP alone,1 justifying confirmation of this finding in a larger randomized trial.
“DLBCL consolidation therapy is a setting in which rituximab maintenance has failed to show benefit in two randomized clinical trials, whereas multiple Phase 2 studies have shown encouraging results for ZEVALIN consolidation in this setting. We feel that success of ZEVALIN in the ZEST study could lead to approval for its use in DLBCL consolidation therapy,” stated Dr. Shrotriya.
About Non-Hodgkin’s Lymphoma
According to the SEER database, it estimated that more than 79,000 individuals will be diagnosed with and more than 20,000 will die of lymphoma in 2012. Of these, approximately 70,000 will be diagnosed with non-Hodgkin’s lymphomas, resulting in approximately 18,940 deaths in the United States in 2012.2 Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkin’s lymphoma, comprising approximately 30% of cases.3
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. 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. Prognosis and treatment depend on the stage and type of disease. DLBCL occurs primarily in older people, with a median age at diagnosis of 69.
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.
