Fixed Dose Radioimmunotherapy (Zevalin, Yttrium-90 Ibritumomab Tiuxetan) for Patients With Incomplete Response to Chemotherapy 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.

- Safety (rate of occurrence of defined toxic events) and Efficacy (objective response rate) [ Time Frame: Throughout the study ] [ Designated as safety issue: Yes ]For efficacy, the objective response rate (CR + PR) at 12 and 104 days following radioimmunotherapy will be determined. For safety, the rate of occurrence of defined toxic events including non-engraftment and unacceptable biodistribution of 90Y Zevalin occurring by day +42 following transplant will be determined. The intervention will be considered safe if the rate of toxic events is less than 20%.
- Evaluate the kinetics of engraftment in patients who proceed to myeloablative chemotherapy after receiving 90Y Zevalin® (ibritumomab tiuxetan). [ Time Frame: Transplant through day 42 ] [ Designated as safety issue: No ]
- Evaluate whether the degree of CD20 expression on plasma cells and/or targeting of post-germinal center B cells correlate with toxicity, response, biodistribution and other clinical parameters. [ Time Frame: 2 weeks prior - 2 weeks post transplant ] [ Designated as safety issue: No ]

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.
Patients with multiple myeloma measurable disease following stem cell mobilization with institution standard high dose cyclophosphamide and peripheral blood stem cell collection are candidates for participation on this trial. 90Y Zevalin targets CD20 expressed on the surface of mature B-cells and is FDA approved for relapsed/refractory low grade lymphoma. This is a single arm, phase II safety and efficacy study of 90-Y Zevalin in multiple myeloma. Subjects will receive cold antibody (Rituximab 100mg/m2) followed by 5 mCi test dose of 111-In Zevalin on transplant day -21. Gamma camera images are obtained 48 to 72 hours after 111-In Zevalin to document appropriate / expected distribution of radiotracer. On transplant day -14, subjects will receive another cold antibody dose followed by 90Y Zevalin 0.4 mg/kg (max 32 mCi) as single dose. Subjects are admitted for transplant on day -3 and proceed with institution standard high dose melphalan (200mg/m2) on day -2. Subjects are followed for safety for 6 weeks after transplant.
