Rituximab Maintenance After Autologous Transplantation

July 27, 2012 updated by: M.D. Anderson Cancer Center

Maintenance Therapy With Rituximab After Autologous Transplantation for Non-Hodgkin's Lymphoma

The goal of this clinical research is to see if Rituxan (rituximab) therapy given after high dose chemotherapy and transplant of a patients own stem cells will prevent or delay the return of the lymphoma.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Rituxan is a mouse antibody that has been changed to make it similar to a human antibody. Antibodies are proteins that can protect the body from foreign invaders, such as bacteria and viruses, by binding to substances called antigens. Rituxan works by binding to a protein, called the CD20 protein (which is found on the surface of normal and cancerous B-lymphocytes). This binding may help to destroy the B-lymphocytes.

Before the study begins, you will have a physical exam, routine blood tests (1-2 tablespoons), and urine tests. Women who are able to have children must have a negative blood pregnancy test. You will also have a chest x-ray and an ECG (test to measure the electrical activity of the heart). The status of the lymphoma will be evaluated by bone marrow biopsy. To collect a bone marrow sample, an area of the hip or chest bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle. CT scans and gallium or PET scans will be performed. If you had lymphoma in other areas of your body additional tests may be needed as determined by your treating physician. Tests to evaluate the status of the lymphoma will be repeated before each cycle of chemotherapy. If your white count is low you may need injections of NeupogenTM (growth factor) daily till your white blood cell count is high enough to start the next round of treatment.

You will be randomly assigned (as in the toss of a coin) to one of two treatment groups. Participants in one group will receive rituximab. Participants in the other group will not receive rituximab. There is an equal chance of being assigned to either group.

Treatment will start between 5-6 months after your stem cell transplant. If you are assigned to the rituximab group, you will receive a total of 4 cycles of treatment. Each cycle will be given 6 months apart. Each cycle is made up of 4 doses of rituximab given once a week for 4 weeks. If the disease returns or intolerable side effects occur while on treatment, you will be taken off the study. You may still be able to receive rituximab outside of this study if your treating physician decided that it is okay.

Treatment will be given on an outpatient basis. The treatment can be given at M. D. Anderson or by your local cancer doctor. Patients who are assigned to the rituximab arm must be willing to get their first and third cycle (all 4 doses) at M. D. Anderson, if their local physician is unable to draw and ship samples to the central laboratory for rituximab levels. Blood will be drawn (approximately one teaspoon) before and after the first and fourth dose and before the second and third dose of those two treatment cycles. The treatment will be given by vein over a period of several hours. Participants who have easily accessible veins may get this treatment by having a temporary needle placed in the vein for the treatment. For participants who do not have easily accessible veins, a central venous catheter (long plastic tube - CVL) will be placed in a big vein of the arm or chest.

Participants who do not receive rituximab will be followed every 6 months at M. D. Anderson as is standard of care.

All participants (even those who do not receive the rituximab) will have to return to M. D. Anderson every 6 months for a period of 3 years (from the date of enrollment) to have the lymphoma evaluated. The status of the lymphoma will be evaluated by blood tests (1-2 tablespoons), CT scans, PET or Gallium scans and bone marrow biopsy.

This is an investigational study. Rituximab has been approved by the FDA. About 90 patients will take part in the study. All will be enrolled at M. D. Anderson.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
