Spots Global Cancer Trial Database for Alemtuzumab + Rituximab Consolidation in CLL

Study Description

Brief Summary: The goal of this clinical research study is to find out how well Campath (alemtuzumab), Rituxan (rituximab), or a combination of the 2 drugs may control Chronic Lymphocytic Leukemia (CLL) that is left after chemotherapy. The safety of these drugs will also be studied.

Detailed Description: Study Drugs: Alemtuzumab and rituximab are both monoclonal antibodies. Monoclonal antibodies are proteins designed to attach to a protein on the surface of the leukemia cell. By attaching to the leukemia cell, monoclonal antibodies alert the immune system to target that cell and kill it. Study Groups: If you are found to be eligible to take part in this study, you will be randomly assigned (as in the roll of a dice) to 1 of 3 groups. Group 1 will receive rituximab alone. Group 2 will receive alemtuzumab alone. Group 3 will receive both drugs together. At the beginning of the study, the chance of being assigned into any of the groups is about equal. However, once enough participants are on study and the response rate in each group is known, you will have a slightly better chance of being assigned to the group with the highest response rate. Study Drug Administration: Group 1: If you are in Group 1, rituximab will be given through a needle in your vein 1 time a week for 4 weeks. The first time you receive rituximab, it will be given over about 4-6 hours. Depending on any side effects you may have, the later infusions may be given over about 2-4 hours. Before each dose of rituximab, you will receive drugs such as benadryl (diphenhydramine), Tylenol (acetaminophen), and sometimes steroids (either by mouth or into your vein) to try and prevent and/or help control side effects such as fevers and chills. To help prevent infections, you will take the antibiotic valacyclovir (or a similar drug). Valacyclovir is taken 1 time a day every day. Your doctor will describe this to you in more detail. Group 2: If you are in Group 2, alemtuzumab will be given as an injection under your skin 3 times a week for 13 weeks. You will have to come to the clinic for each dose, learn how to inject it yourself, or have someone else taught how to inject you. To help prevent infections, you will take the antibiotic trimethoprin/sulfamethoxazole (SMX). Your doctor will tell you if you will take the tablet 2 times a day either 3 times a week (Monday, Wednesday, and Friday) or 2 times a week (Saturday and Sunday). You will also take either the antibiotic valganciclovir or valacyclovir. Valganciclovir tablets are taken 2 times every day. Valacyclovir is taken 1 time a day every day. You will continue to take the antibiotics for at least 3 months after your last dose of alemtuzumab. Group 3: If you are in Group 3, rituximab will be given through a needle in your vein 1 time a week for 4 weeks. The first time you receive the rituximab, it will be given over about 4-6 hours. Depending on any side effects you may have, the later infusions may be given over about 2-4 hours. Alemtuzumab will be given as an injection under your skin 3 times a week for 13 weeks. You will have to come to the clinic for each dose, learn how to inject it yourself, or have someone else taught how to inject you. Before each dose of rituximab, you will receive drugs such as benadryl (diphenhydramine), Tylenol (acetaminophen), and sometimes steroids (either by mouth or into your vein) to try and prevent and/or help control side effects. To help prevent infections, you will take the antibiotic trimethoprin/sulfamethoxazole (SMX). Your doctor will tell you if you will take the tablet 2 times a day either 3 times a week (Monday, Wednesday, and Friday) or 2 times a week (Saturday and Sunday). You will also take either the antibiotic valganciclovir or valacyclovir. Valganciclovir tablets are taken 2 times every day. Valacyclovir is taken 1 time a day every day. You will continue to take the antibiotics for at least 3 months after your last dose of alemtuzumab. Study Visits: Every week while you are receiving therapy, blood (about 1 tablespoon) will be drawn for routine tests. Six (6), 12, and 18 weeks (+/- 1 week) after you begin receiving the study drug(s) and then every 6 months (+/- 1 month) after that, you will have bone marrow biopsies and/or aspirates to check the status of the disease and to check for residual disease. Every 6 months (+/- 3 months) after you have stopped receiving therapy, you will have a physical exam and blood (about 1 tablespoon) will be drawn for routine tests. If you are in Group 2 or 3, during Week 3 and 6, blood (about 1 teaspoon) will be drawn to check for the cytomegalovirus (CMV) infection. This infection may occur in people with weakened immune systems. If your doctor thinks it is necessary, you will have a chest x-ray and/or other scans. Length of Study: If you are in Group 1, you will take the study drug for up to 4 weeks. If you are in Groups 2 or 3, you will take the study drug(s) for up to 13 weeks. You will be taken off treatment early if you have intolerable side effects. You will remain on study as long as the disease does not get worse. This is an investigational study. Rituximab is FDA approved and commercially available for non-Hodgkin's lymphoma. However, it is not approved for the treatment of CLL. Alemtuzumab is FDA approved and commercially available. It has been approved for the treatment of CLL when given by vein. It has not been approved to be given as an injection under the skin or for treatment after chemotherapy. Up to 100 patients will take part in this study. All will be enrolled at M. D. Anderson.
