Zevalin for Patients With Incomplete Response to Chemo Prior to Autologous Stem Cell Transplant for Multiple Myeloma
The study involves the use of a targeted form of radiation, in addition to standard high dose chemotherapy and stem cell transplant for multiple myeloma. The use of targeted radiation is designed to kill more multiple myeloma cells while avoiding the side effects of standard radiation. This type of targeted radiation (also known as radioimmunotherapy) has been approved by the Food and Drug Administration (FDA) for the treatment of a related disease, lymphoma under the trade name, Zevalin©. Zevalin© has been added to high dose chemotherapy and stem cell transplants for patients with lymphoma and is now being studied in this clinical trial for patients with multiple myeloma. This trial is only available at Tufts Medical Center.
The proposed clinical trial will test whether CD20-targeted radio-immunotherapy can be safe and effective when integrated into a standard regimen of myeloablative chemotherapy and autologous stem cell rescue in patients with measurable disease prior to high dose chemotherapy and autologous stem cell transplant for multiple myeloma.

|Official Title:||A Phase II, Safety and Efficacy Study of Fixed Dose Radioimmunotherapy (Zevalin, Yttrium-90 Ibritumomab Tiuxetan) for Patients With Incomplete Response to Chemotherapy Prior to Autologous Stem Cell Transplant for Multiple Myeloma|
- Safety and Efficacy [ Time Frame: Through day +104 following immunotherapy ]Efficacy: objective response rate (CR + PR) at 12 and 104 days following radioimmunotherapy. Safety: the rate of occurrence of defined toxic events including non-engraftment and unacceptable biodistribution of 90Y Zevalin occurring by day +42 following transplant. Response determined according to Blade' Criteria (Bladé J, Br J Haematol.1998 Sep;102(5):1115-23) for multiple myeloma; Response based on reduction of monoclonal protein (M-protein) from initial presentation.
- Time to Engraftment in Patients Who Proceed to Myeloablative Chemotherapy After Receiving 90Y Zevalin® (Ibritumomab Tiuxetan). [ Time Frame: Transplant through day 42 ]Number of days from stem cell infusion (day +0) to day of neutrophil engraftment (first of three consecutive days with absolute neutrophil count > 500)
- Degree of CD20 Expression on Plasma Cells and/or Targeting of Post-germinal Center B Cells Correlation With Toxicity, Response and Biodistribution [ Time Frame: 2 weeks prior - 2 weeks post transplant ]CD20 immunohistochemical staining of plasma cells on baseline bone marrow biopsy specimen, graded on qualitative scale (0 to +++)

1.5mg of 111In Zevalin (containing 5 mCi of 111In) will be used for radioimaging on study day +1. 90Y Zevalin will be administered seven to nine days after 111In Zevalin administration. The dose of 90Y Zevalin will be 0.4 mCi/kg, capped at a maximum dose of 32 mCi.
Drug: indium-111-ibritumomab tiuxetan
1.5mg of 111In Zevalin (containing 5 mCi of 111In) will be used for radioimaging. 111In Zevalin will be administered by a 10 minute slow IV push injection immediately following completion of the rituximab infusion. 111In Zevalin may be injected by stopping the flow from the IV bag and injecting the radiolabeled antibody directly into the IV line. A 0.22 micron filter must be on line between the drug infusion port and the patient. The line must be flushed with at least 10cc of normal saline after 111In Zevalin has been injected.
Other Name: 111 In ZevalinDrug: 90Y Zevalin
Each patient will receive a single therapeutic dose of 90Y Zevalin at a dose of 0.4 mCi/kg, capped at a maximum dose of 32 mCi. 90Y Zevalin will be administered intravenously as a slow IV push over 10 minutes. 90Y Zevalin may be directly infused by stopping the flow from the IV bag and injecting the radiolabeled antibody directly into the IV line. A 0.22 micron filter must be on line between the syringe and the infusion port. The line must be flushed with at least 10cc normal saline after 90Y Zevalin has been infused.
