BACKGROUND The purpose of this study was to quantitatively evaluate the tumor accumulation and heterogeneity of (111)In-ibritumomab tiuxetan (Zevalin®) and tumor accumulation of (18)F-fluoro-deoxyglucose (FDG) and compare them to the tumor response in B-cell non-Hodgkin's lymphoma patients receiving (90)Y-ibritumomab tiuxetan (Zevalin®) therapy. METHODS Sixteen patients with histologically co...
87 Rationale • Ibritumomab tiuxetan (ZevalinTM) is an yttrium 90–labeled anti-CD20 monoclonal antibody. Ibritumomab is the murine counterpart of rituximab, another antibody active in non-Hodgkin’s lymphoma (NHL). It is covalently linked to tiuxetan, which provides a high-affinity chelation site for indium 111 or for 90Y. In phase I/II studies, ibritumomab tiuxetan produced response rates of 67%...
Yttrium 90 ibritumomab tiuxetan consists of the murine monoclonal antibody ibritumomab securely bound to the second-generation chelator tiuxetan, which attaches the high-energy pure beta emitter (90)Y, for therapy, or the gamma emitter indium 111, for imaging. The biodistribution of the therapeutic dose of (90)Y ibritumomab tiuxetan can be predicted by using an imaging dose of the antibody labe...
Radioimmunotherapy is a new cancer therapy that combines the cytotoxicity of radiation with the tumor-specific targeting of monoclonal antibodies. Yttrium 90 (Y-90) ibritumomab tiuxetan (Zevalin, IDEC Pharmaceuticals Corporation, San Diego, CA) is indicated for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell non-Hodgkin's lymphoma (NHL), includ...
UNLABELLED Ibritumomab tiuxetan is an anti-CD20 murine IgG1 kappa monoclonal antibody (ibritumomab) conjugated to the linker-chelator tiuxetan, which securely chelates (111)In for imaging or dosimetry and (90)Y for radioimmunotherapy (RIT). Dosimetry and pharmacokinetic data from 4 clinical trials of (90)Y-ibritumomab tiuxetan RIT for relapsed or refractory B-cell non-Hodgkin's lymphoma (NHL) w...
UNLABELLED We retrospectively evaluated our single-center clinical experience with (90)Y-ibritumomab tiuxetan and (131)I-tositumomab for therapy of refractory non-Hodgkin's lymphoma (NHL). We evaluated the hypothesis that the patient-specific dosing regimen used with (131)I-tositumomab results in less bone marrow toxicity than does the weight-based dosing regimen used with (90)Y-ibritumomab tiu...
PURPOSE This study aimed to evaluate the efficacy and safety of the treatment with (90)Y-ibritumomab tiuxetan following a short-course of rituximab with cyclophosphamide-adriamycin-vincristine-prednisone (R-CHOP) in high-risk elderly patients with previously untreated diffuse large B-cell lymphoma (DLBCL). EXPERIMENTAL DESIGN From December 2006 to October 2008, 55 high-risk elderly (age > or ...
The development of radiolabeled antibodies against CD20 has facilitated targeted treatment of follicular lymphoma (FL). By using (90)Y-ibritumomab tiuxetan (Zevalin((R))), a radionuclide (yttrium-90, linked by the chelator tiuxetan to the antibody ibritumomab) is brought into the vicinity of lymphoma cells. By the so-called cross-fire effect, this beta emitter has the capacity to destroy not on...
We conducted a phase 1/2 trial of high-dose 90Y-ibritumomab tiuxetan in combination with high-dose etoposide (VP-16) 40 to 60 mg/kg (day -4) and cyclophosphamide 100 mg/kg (day -2) followed by autologous stem cell transplantation (ASCT) in 31 patients with CD20+ non-Hodgkin lymphoma (NHL). Patients underwent dosimetry (day -21) with 5 mCi (185 MBq) 111In-ibritumomab tiuxetan following 250 mg/m2...
90Y-ibritumomab tiuxetan is a novel radioimmunotherapeutic agent recently approved for the treatment of relapsed or refractory low-grade, follicular, or CD20+ transformed non-Hodgkin's lymphoma (NHL). (90)Y-ibritumomab tiuxetan consists of a murine monoclonal antibody covalently attached to a metal chelator, which stably chelates (111)In for imaging and (90)Y for therapy. Both health care worke...
