A Phase II Study of Bevacizumab and Bortezomib in Patients With Relapsed/Refractory Multiple Myeloma
- Registration Number
- NCT00464178
- Lead Sponsor
- Hackensack Meridian Health
- Brief Summary
The purpose of this study is to determine whether the combination of bevacizumab and bortezomib have increased efficacy in the treatment of relapsed/ refractory multiple myeloma.
- Detailed Description
Rationale: With the identification of thalidomide as an active agent in Multiple Myeloma, the role of angiogenesis in its pathogenesis has become a subject of much investigation. Micro vessel density (neovascularization) is inversely related to prognosis in Multiple Myeloma. Response to thalidomide was felt to correlate with a decline in microvessel density (Singhal et al NEJM). While the mechanism of neovascularization is yet to be fully elucidated, a number of models have shown VEGF to play a central role.
Thalidomide has been shown to synergize with a number of agents used to treat MM, including bortezomib. (Wang et al ASH 2005) This would justify the use of other therapeutics with known antiangiogenic activity in conjunction with established antimyeloma therapies.
Bortezomib, which has the precedence of known synergy with Thalidomide and has an extremely well established optimal dose, schedule, response rate, event free survival, and overall survival would make it an excellent candidate for combination therapy with other established antiangiogenic compounds.
There have been several reports of the role of VEGF in multiple myeloma. It has been shown that multiple myeloma cells secreteVEGF, which further promotes production of IL-6 in BMSCs, as well as migration and proliferation of the tumor cells. Thus VEGF is both an autocrine growth factor and trigger of IL-6-mediated paracrine multiple myeloma cell growth. Recent reports have highlighted the major role of VEGF in multiple myeloma pathogenesis, demonstrating the VEGF also increases microvessel density in the bone marrow. VEGF also inhibits dendritic cells. Taken together, these preclinical reports make strong suggestion for the promise of VEGF targeted agents in multiple myeloma (Le Gouill et al 2004).

Group Intervention Description Bortezomib and bevacizumab Bortezomib Bortezomib will be administered at 1.3 mglm2 IVP on Days 1. 4, 8, and 11. Response will be assessed subsequent to each cycle. A total of 8 cycles would beplanned. Patients would be removed subsequent to Cycle 2. if progression of disease is documented.
- Primary Outcome Measures
Name Time Method Overall Survival (OS) - Number of Participants Alive at Study Completion 18 months The secondary objective of this study is to assess the safely and tolerability of the combination treatment of bevacizumnab and bortezomnib. Adjustments in the dosing schedule of bortezomib would be made for patients with adequate response as per Blade criteria and continue until disease progression or 18 months
Median Number of Cycles to Tumor Progression (TTP) 18 months Study Schema: Bortezomib will be administered on Days 1. 4, 8, and 11. Response will be assessed subsequent to each 21-day cycle. Progression is defined using the Bladé criteria, defined progression as an increase of \>25% in paraprotein or urinary light chain excretion (or marrow plasma cell percentage in the marrow
