Conditions: Mantle-Cell Lymphoma
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 5
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the effects (good and bad) of the combination of ibritumomab tiuxetan (Zevalin) and bortezomib (Velcade) in patients with relapsed/refractory mantle cell lymphoma.

Zevalin is a monoclonal antibody that is combined with a radioactive substance and given with another monoclonal antibody called rituximab (Rituxan). It works by attaching to cancer cells and releasing radiation to damage those cells. Both Zevalin and Rituxan are given in this study, along with Velcade.

Detailed description:
This is a non-randomized, unblinded single arm Phase II trial to evaluate the combination of yttrium90 ibritumomab tiuxetan and bortezomib in patients with relapsed/refractory mantle cell lymphoma (MCL). Standard hematology and chemistries, imaging and bone marrow biopsies will be done.

Research tests: 17cc of blood will be collected at screen, Day 8 OR 11 and month 3. Samples will be collected and stored for future analysis. These analyses may include but are not limited to measurements of proteasome inhibition. No genetic studies will be performed on these samples. Samples will be destroyed at the end of the study.

Primary Objective Estimate the overall response rate (CR + PR) of the combination of bortezomib and ibritumomab tiuxetan in patients with relapsed/refractory mantle cell lymphoma.

Secondary Objectives

* Estimate the progression free and overall survival in patients with relapsed/refractory mantle cell lymphoma who receive bortezomib and ibritumomab tiuxetan.
* Assess the toxicity of the combination of bortezomib and ibritumomab tiuxetan in patients with relapsed/refractory MCL.

Arms:
arm 1: Drug: Rituximab, Bortezomib,Y90 ibritumomab tiuxetan

Other Names:

Rituxan Velcade Zevalin

Rituximab 250mg/m2 will be given on day 1 and on day 8. Bortezomib 1.5mg/m2 will be given on Days 1, 4, 8, and 11. Y90 ibritumomab tiuxetan will be given on Day 8. Dosage will be based on the platelet count obtained at the time of study enrollment. The dose will be 0.4 millicurie (mCi)/kg unless the enrollee's platelets are between 100,000 and 150,000 in which case a dose of 0.3mCi/Kg will be used. Patients who weigh over 80 Kg will receive a maximum dose of 32mCi.
