Participant milestones

Participant milestones
Measure
Rituxan
All study patients will receive Rituxan 1g on day 15 from start of desensitization and either 3M or 6M post transplant depending on the presence of DSA. Rituxan: Rituximab (1gm) given on day# 15. Transplanted patients will receive an additional dose of Rituximab at 3M if DSA remains or 6M if denovo DSA present.
