Trial Outcomes & Findings for Desensitization in Kidney Transplantation (NCT NCT00908583)
NCT ID: NCT00908583
Last Updated: 2016-04-01
Results Overview
Number of living donor transplant candidates who convert to a negative flow T- and B-cell crossmatch via desensitization and are subsequently transplanted
COMPLETED
PHASE4

Participant Flow
Subjects could be enrolled in multiple study phases. Enrollment in phases 1-2 was an adaptive approach and was fixed a priori in Phases 3-5. The adaptive approach was based on treatment effect (immunodominant antibody (iAb) reduction).
44 subjects received 52 treatments in this study. 7 subjects were enrolled in multiple phases. Four patients received treatment in two study phases (two patients were enrolled in Phases 1 and 2, one patient was enrolled in study Phases 1 and 3, and one patient was enrolled in Phases 2 and 3). One patient was enrolled in Phases 1, 2 and 4.

SECONDARY outcome
Timeframe: 6 months post transplantPopulation: One graft loss occurred due to graft thrombosis within 24 hours (due to unrecognized hypercoagulability disorder without AMR). Two patients were transplanted at other centers and data was not available. This dropped the number of analyzed patients to 16 from 19.
