Zevalin (Ibritumomab Tiuxetan) for Early Stage Indolent Lymphomas

Phase II Study of Zevalin for the Treatment of Early-Stage Indolent Lymphomas

The goal of this clinical research study is to find out if giving (Rituxan) rituximab with 90Y (ibritumomab tiuxetan) (90 Y Zevalin®) may be effective in treating low-grade lymphoma. The safety of this combination treatment will also be studied.

Study Overview

• Status: Completed
• Conditions: Lymphoma
• Intervention / Treatment: Drug: Ibritumomab Tiuxetan (Zevalin); Drug: Rituximab

Detailed Description

90 Y Zevalin and rituximab are both designed to attach to lymphoma cells, causing them to die.

Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a physical exam. Blood (about 2 to 3 teaspoons) and urine will be collected for routine tests. You will have a chest x-ray and computerized tomography (CT) scans of the neck, chest, abdomen (stomach area), and pelvis.

A PET scan is also recommended. A PET (Positron Emission Tomography) scan is a medical technique that monitors the activity in the brain and other organs by tracking the movement of a special radioactive solution through the body. The radioactive solution is either inhaled as a mist or injected into a vein. The radioactive solution is usually made from simple sugar that has radioactive particles attached to it. After the solution is injected into a vein or inhaled, the PET scanner takes pictures of the radioactive solution as it moves through the body and collects in various organs. By watching how the solution travels through the body and studying where the solution collects, researchers can learn the extent of disease in certain organs in the body.

You will have an electrocardiogram (ECG -- a test that measures the electrical activity of the heart). You will have a bone marrow aspirate and biopsy performed. To collect a bone marrow aspirate and biopsy, an area of the hip or chest bone is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a large needle. Women who are able to have children must have a negative blood or urine pregnancy test.

If you are found to be eligible to take part in this study, you will be given diphenhydramine (Benadryl) by vein and you will take acetaminophen (Tylenol) by mouth before each dose of rituximab. This is done to help decrease the risk of developing side effects of rituximab. You will then receive 1 dose of rituximab by vein over about 4-6 hours on Day 1 of treatment. After treatment with rituximab, you will then be given 111 In Zevalin (this is a radioactive agent that binds to rituximab to help with imaging exams), by vein over about 10 minutes. This is so researchers can use a special camera to see where the drug is in your body.

You will have imaging performed (on a camera, like an x-ray) on either Day 2 or 3. On Day 8 (7 days after the first dose of rituximab) you will receive a second dose of rituximab. You will also be given Benadryl, Tylenol, and 90Y Zevalin in the same manner as on Day 1.

If you experience intolerable side effects while on this study, you may be removed from this study. Your treatment on the study will end on Day 8.

You will return for follow-up tests for 4 years. Blood (about 2 tablespoons) will be drawn weekly for the first 3 months. Blood (about 2 tablespoons each time) will also be drawn at month 6 and 9 of the first year, and every 6 months in the second, third, and fourth years. You may also have CT scans, PET scans (which are recommended), x-rays, and bone marrow biopsies and aspirates performed, if your doctor thinks they are necessary.

Your participation on this study will end in about 4 years.

This is an investigational study. 90 Y Zevalin and rituximab are FDA approved and commercially available. Their use in this study is investigational. Up to 36 patients will take part in this multicenter study. Up to 36 patients will be enrolled at M. D. Anderson.

7. Female patients who are not pregnant or lactating.
8. Men and women of reproductive potential who are following accepted birth control methods (as determined by the treating physician, however abstinence is not an acceptable method).
9. Patients determined to have < 25% bone marrow involvement with lymphoma within six weeks of registration (define measurement of a bone marrow aspirate or biopsy).
10. Patient should have at least one lesion measuring >/= 1.5 cm in a single dimension. Measurable cutaneous lesions are allowed.

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Response Rate (ORR)	ORR defined as the percentage of number of complete response (CR), complete response unconfirmed (CRu) or partial response (PR) in patients treated using International Working Group (IWG) revised response criteria for Malignant Lymphoma. ORR to therapy is evaluated after three months using radiographic and clinical parameters to assess response. CR: Complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease-related symptoms. CRu: A residual lymph node mass greater than 1.5 cm in greatest transverse diameter that has regressed by more than 75% in the sum of the products of the greatest diameters (SPD). Individual nodes that were previously confluent must have regressed by more than 75% in their SPD compared to the original mass and indeterminate bone marrow. PR: ≥ 50% decrease in SPD of the six largest dominant nodes or nodal masses. No increase in the size of other nodes, liver or spleen and no new sites of disease.	Up to 5 years; Evaluation at 3-month intervals during Year 1, then every 6 months to Year 4. The median follow-up was 56 months for censored observations.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression Free Survival (PFS) Rate at 3 Years	PFS measured, in a responder, from the date when a CR, CRu or PR is first noted to the first date at which progressive disease is observed or death. An ongoing PFS interval occurs when there is a responder for whom progressive disease has not been noted. Progression of disease defined as enlargement of liver/spleen, new sites observed, new or increased lymph nodes or lymph node masses, or reappearance of bone marrow.	Evaluation at 3-month intervals during the first year and then every 6 months until year 3
