CAMBRIDGE, Mass., April 18 /PRNewswire-FirstCall/ -- Millennium Pharmaceuticals, Inc. (Nasdaq: MLNM - News) along with co-development partner Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) today announced the initiation of a Phase III clinical trial of VELCADE in combination with rituximab in patients with relapsed or refractory follicular lymphoma, a subtype of non-Hodgkin’s lymphoma (NHL). This study builds on clinical data observed in previous trials of VELCADE that showed high objective response rates and a favorable safety profile across a variety of lymphomas.
“We accelerated the timeline for initiating this high-priority trial,” said Robert Tepper, M.D., President, Research & Development, Millennium Pharmaceuticals, Inc. “Based on previous study results that demonstrated substantial single-agent and combination activity in this patient population, we are excited about the potential of VELCADE to benefit patients with this form of NHL, a disease that is not curable with standard therapy.”
The Phase III study is expected to enroll approximately 670 patients with relapsed or refractory, rituximab naïve or sensitive follicular NHL. Patients will be randomized to either the combination regimen of once-weekly VELCADE plus rituximab or rituximab alone. The primary endpoint is progression-free survival. Secondary endpoints of the study include the overall response rate and duration of response as assessed by the International Workshop to Standardize Response Criteria for NHL (IWRC). The weekly dose of VELCADE in this study is 1.6 mg/m2 and rituximab will be administered at 375 mg/m2.
This study builds on previous clinical trials results of VELCADE in NHL, including data from a Phase II study presented in December 2005 at the 47th Annual Meeting of the American Society of Hematology. In a randomized, multi- center Phase II study comparing weekly and twice-weekly VELCADE in combination with the standard-weekly dose of rituximab, the more convenient weekly arm showed a response rate similar to that of the twice-weekly arm, with an improved safety profile. Results from the 74 evaluable patients (39 in the weekly arm and 35 in the twice-weekly arm) included overall response rates, including complete responses, of 54 percent in the weekly arm, and 51 percent in the twice-weekly arm with a similar total amount of drug received in both treatment arms. Additionally, data presented at the 9th International Conference of Malignant Lymphoma in Lugano, Switzerland in June 2005 demonstrated response rates for single-agent VELCADE as high as 56 percent in patients with relapsed or refractory follicular lymphoma. The most common adverse events seen in these trials were gastrointestinal symptoms, neutropenia, thrombocytopenia, fatigue and peripheral neuropathy.
About Non-Hodgkin’s Lymphoma (NHL)
Non-Hodgkin’s lymphoma is the most common hematological cancer and the fifth leading cause of cancer death in the U.S. There are approximately 56,400 new cases diagnosed per year, it is responsible for 19,200 deaths annually and is the second fastest growing form of cancer in the U.S.(1) The prevalence of NHL is approximately 400,000, including 77,000 patients with follicular lymphoma and approximately 10,000 with mantle cell lymphoma.(2,3) According to the American Cancer Society, the incidence of NHL has more than doubled since the 1970s. The average age of diagnosis is between 55 and 60.
About VELCADE
VELCADE is indicated for the treatment of multiple myeloma patients who have received at least one prior therapy. VELCADE is contraindicated in patients with hypersensitivity to bortezomib, boron, or mannitol. VELCADE should be administered under the supervision of a physician experienced in the use of antineoplastic therapy.
Risks associated with VELCADE therapy include new or worsening peripheral neuropathy, hypotension observed throughout therapy, cardiac and pulmonary disorders, gastrointestinal adverse events, thrombocytopenia, neutropenia and tumor lysis syndrome. Women of childbearing potential should avoid becoming pregnant while being treated with VELCADE.
In 331 patients who were treated with VELCADE in a Phase III study, the most commonly reported adverse events were asthenic conditions (61%), diarrhea (57%), nausea (57%), constipation (42%), peripheral neuropathy (36%), vomiting (35%), pyrexia (35%), thrombocytopenia (35%), psychiatric disorders (35%), anorexia and appetite decreased (34%), parasthesia (27%), dysesthesia (27%), anemia and headache (26%), and cough (21%). Fourteen percent of patients reported at least one episode of grade 4 toxicity; the most common grade 4 toxicities were thrombocytopenia (4%), neutropenia (2%), and hypercalcemia (2%). A total of 144 patients on VELCADE (44%) reported serious adverse events (SAEs) during the study. The most commonly reported SAEs were pyrexia (6%), diarrhea (5%), dyspnea, pneumonia (4%), and vomiting (3%).
