randomisation

2. Women of childbearing potential with a positive serum or urine pregnancy test or
nursing mothers

3. Subjects with history of malignancy (other than non melanoma skin cancer that has been
totally excised with no recurrence for two years)

4. Subjects with known contraindications to treatment with rituximab

5. Subjects with haemoglobin < 8.5 g/dL, WBC value of < 3000/mm3 or a platelet count of <
50,000/mm3 that is unlikely to resolve prior to randomisation

6. Subjects with a positive ABO crossmatch with donor

7. Subjects with severe diarrhoea or other gastrointestinal disorders that might
interfere with the ability to absorb oral medication and is unlikely to resolve prior
to randomisation

8. Subjects participating in another interventional clinical trial or requiring treatment
with un-marketed investigational drugs or who would be expected to require other
medications prohibited by the protocol

9. Subjects who cannot be followed for the study duration

10. Subjects with disorders or conditions that may interfere with the ability to comply
with study procedures and/or requirements

Additional Exclusion Criteria at Day -2 before Transplantation:

Summary
Brief summary
About one third of prospective kidney transplant recipients have antibodies in their blood
directed against the tissues of their only available kidney donor. Recently,
"desensitisation" treatments when administered pre-transplant have allowed successful
transplantation of these patients despite high rates of acute antibody mediated rejection
(AAMR). The investigators propose to test in a randomised controlled trial whether rituximab,
a monoclonal antibody that depletes B-lymphocytes, will safely lower antibody mediated
rejection (AMR) rates when added to "standard" therapy. The investigators will also test
whether rituximab enables more patients to achieve a negative crossmatch against their donor
and thereby allow more transplants to proceed.
