Radioimmunotherapy With 90Y Zevalin for Orbital Lymphoma
- To evaluate the efficacy of Zevalin for the treatment of low-grade follicular Non-Hodgkin's lymphoma of the orbit or mucosa-associated lymphoid tissue (MALT) of conjunctiva using radiographic imaging, clinical examination (slit lamp biomicroscopy and external examination of the conjunctiva), and external photography whenever possible.
- To establish the safety profile in this patient population using clinical examination including slit lamp biomicroscopy, and evaluation of the tear film with Schirmer's test.
- To establish the dosimetry for Zevalin in the orbit in the first 3 patients who agree to undergo dosimetry.

Primary Purpose: Treatment
|Official Title:||Pilot Trial of Radioimmunotherapy With Yttrium 90-Labeled (90Y) Zevalin for Low-Grade Follicular Non-Hodgkin's Lymphoma or MALT of the Orbit/Conjunctiva|
- Number of Participants With Complete Response (CR) or Partial Response (PR) [ Time Frame: 3 months ]Tumor response to therapy measured by tumor size as measured radiographically at baseline and at three months from baseline. Tumor response classified as complete response (CR) or partial response (PR), or stable disease (SD), or progressive disease (PD) using International Workshop Standardized Response Criteria (IWC) for Non-Hodgkin's Lymphomas. If the orbital/ocular adnexal lymphoma was not evaluable radiographically, clinical evaluation using slit lamp biomicroscopy was used to assess PR or CR.

Experimental: Zevalin + Rituximab
Rituximab 250 mg/m^2 intravenous (IV) over 4-6 hours for 2 weeks, + Zevalin 5 millicurie (mCi)/kg IV over 30 minutes for 1 week, followed by 0.3 mCi/kg or 0.4 mCi/kg 90Y-Zevalin based on platelet counts for 1 week.
250 mg/m^2 IV over 4-6 hours for 2 weeks.
Other Name: RituxanDrug: Zevalin
5 mCi/kg IV over 30 minutes for 1 week, followed by 0.3 mCi/kg or 0.4 mCi/kg 90Y-Zevalin based on platelet counts for 1 week.
Rituximab and Zevalin are monoclonal antibodies that bind to lymphoma cells and cause cell death.
As is the case for all patients with orbital lymphoma, an orbital biopsy must be performed to confirm the diagnosis and status of the orbital lymphoma. The study doctors must first make sure that the disease has not spread too much and is not severe enough to require immediate treatment with chemotherapy before you can begin treatment on this study. You will have about 4 teaspoons of blood drawn. Women who are able to have children must have a negative blood or urine pregnancy test.
You will receive two injections of rituximab by vein over about 4 to 6 hours. This is followed by an infusion of Zevalin over about 30 minutes on the same day. Whole body images will be performed immediately and at 4-6, 24, 72, and 144 hours after receiving Zevalin. About 1 week later, you will receive a second infusion of rituximab and Zevalin.
You may be taken off the study if your orbital lymphoma does not respond within three months of receiving rituximab and Zevalin. Researchers will measure your response to therapy using magnetic Resonance imaging (MRI) of the orbit and an evaluation of the eye in the clinic. If you are taken off study, you will be given the option of receiving external beam radiation therapy as treatment for the disease.
Follow-up evaluations will be done every 3 months for 2 years and every 6 months for Years 3 and 4. This testing is considered standard of care and would include medical history, physical exam, blood tests, and urine tests. The status of the disease will be evaluated using CT scan or MRI of the orbit every 3 months for the first year and every 6 months for Years 2, 3, and 4. Blood tests (about 4 teaspoons each) will be every 3 months for the first year and may be continues every 3 to 6 month until they become negative or you start another anti-cancer therapy.
This is an investigational study. Zevalin and rituximab are both FDA approved but their use together in this study is investigational. A total of up to 12 patients will take part in this study. All will be enrolled at The University of Texas (UT) MD Anderson Cancer Center.
