简要总结
The goal of this clinical research study is to see if low intensity chemotherapy given together with the new drug 90Y Zevalin, followed by a transplant of blood or marrow stem cells from a donor can increase the length of remission in patients with leukemia and lymphoma. The safety of this treatment will also be studied.
详细描述
Rituxan is an antibody made from human and mouse protein. It reacts with a certain antigen on lymphoma cells and causes the body's immune system to destroy the lymphoma cells. 90Y Zevalin and 111In Zevalin are murine-based antibodies combined with a radioactive agent that can also destroy lymphoma cells. Unlike Rituxan, 90Y Zevalin cannot be traced by regular scanning and requires indium to determine its distribution through the body.
Before treatment starts, patients will have a physical exam, including blood tests and urine tests. Women who are able to have children must have a negative blood pregnancy test. Bone marrow samples will be taken. For bone marrow sampling, a large needle is placed in the hipbone after it has been numbed. The bone marrow is then withdrawn through the needle. Patients will have a chest x-ray, computed tomography (CT) scans, an EKG, and tests of lung function.
Blood tests, urine tests, bone marrow sampling, and x-rays will be done as needed to track the effects of the transplant. Patients will have transfusions of blood and platelets as needed. Blood tests will be done daily while patients are in the hospital.
Patients in this study will receive an unlabeled antibody form of Y2B8 called rituxan by vein followed by a dose of 111In Zevalin by vein. 111In Zevalin includes the radioactive agent indium, which shows up when patients have x-rays or scans. The scans can show where and how fast the drug travels in the body and how long the drug stays in the body. Doctors need to be able to see how much of the drug goes to the tumor and how much goes to normal organs to see if it is safe to give 90Y Zevalin on an outpatient basis. A scan will be taken 48 to 72 hours after 111In Zevalin is given.
If the radiation in the 111In Zevalin is not a threat to normal organs and bone marrow, patients may receive 90Y Zevalin. Seven days after the 111In Zevalin injection, patients will receive a second dose of rituxan followed by a dose of 90Y Zevalin.
