Study Details

Study Description

Brief Summary

The goal of this clinical research study is to learn if the combination of lenalidomide and rituximab can help to control CLL. The safety of this drug combination will also be studied.

Lenalidomide is designed to change the body's immune system. It may also interfere with the development of tiny blood vessels that help support tumor growth. This may decrease the growth of cancer cells.

Rituximab is designed to attach to cancer cells and damage them, which may cause the cells to die.

Detailed Description

Study Drug Administration:

If you are found to be eligible to take part in this study, you will begin taking the study drugs in 28-day cycles. One time a week during Cycle 1, you will receive rituximab by vein. During Cycle 2, you will not receive rituximab. During Cycles 3-12, you will receive rituximab on Day 1 of Cycles 3-12. Your first dose of rituximab will be given over 6-8 hours. If you tolerate your first dose well, you may receive the next doses over 2-4 hours. If the doctor thinks it is needed, the next doses may given over a longer time.

Starting on Day 9 of Cycle 1, you will begin taking lenalidomide by mouth 1 time a day.

The dose and schedule of lenalidomide may change depending on the side effects you may have. You should swallow lenalidomide capsules whole with a glass (8 ounces) water at the same time each day. Do not break, chew, or open the capsules. If you miss a dose of lenalidomide, take it as soon as you remember on the same day. If you miss a dose, it should NOT be made up on another day.

During Cycle 1 only, you will take allopurinol by mouth 1 time a day on Days 1-14 to lower the risk of side effects.

Study Visits:

One (1) time a week during the first 5 weeks, blood (about 1 tablespoon) will be drawn for routine tests.

After the first 5 weeks, blood (about 1 tablespoon) will be drawn for routine tests every 2 weeks until the doctor thinks your dose of lenalidomide can stay the same. After that, blood (about 1 tablespoon) will be drawn every 4 weeks for the rest of the study for routine tests.

At the end of Cycles 3, 6, and 12, you will have a bone marrow biopsy and aspiration to check the status of the disease.

If you stay on study past 12 cycles, once every 6 cycles (Cycles 18, 24, 30, and so on), you will have a bone marrow biopsy and aspiration to check the status of the disease.

Blood (about 1 tablespoon) will be drawn more often if the dose of lenalidomide needs to be changed or if you have intolerable side effects.

Pregnancy Testing:

If you are able to become pregnant, you will have a urine or blood (less than 1 teaspoon) pregnancy test 10-14 days and 24 hours before the first dose of lenalidomide, even if you have not had a menstrual period due to treatment of the disease or had only 1 menstrual period in the past 24 months.

If you have regular or no menstrual cycles, you will then have a urine or blood (less than 1 teaspoon) pregnancy test every week for the first 4 weeks, then every 4 weeks while taking lenalidomide, again as soon as you stop taking lenalidomide, and then 28 days after you have stopped taking lenalidomide.

If you have irregular menstrual cycles, you will have a urine or blood (less than 1 teaspoon) pregnancy test every week for the first 4 weeks, then every 2 weeks while taking lenalidomide, again as soon as you stop taking lenalidomide, and then at 14 days and 28 days after you have stopped taking lenalidomide.

Length of Treatment:

You may receive rituximab for up to 12 cycles. You may continue taking lenalidomide for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drugs if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over once you have completed your last study drug dose (if you are male) or your last follow-up pregnancy test (if you are female).

This is an investigational study. Lenalidomide and rituximab are FDA approved and commercially available. Lenalidomide is approved for the treatment of multiple myeloma and some myelodysplastic syndromes. Rituximab is approved for the treatment of CLL. The combination of these drugs to treat CLL is investigational.

Up to 120 patients will take part in this study. All will be enrolled at M. D. Anderson.
