Brief Summary
The purpose of this study is to determine whether treatment with rituximab (anti-CD20, Rituxan®, MabThera®) in individuals who develop new anti-HLA antibodies after renal (kidney) transplant will prom...
Detailed Description
Organ rejection occurs when a patient's body does not recognize the new organ and attacks it. Data suggest that the development of anti-human leukocyte antigen (HLA) antibodies is an early clinical in...
