Trial Outcomes & Findings for Induction Therapy Study in Live Donor Kidney Transplant Recipients With a Positive Crossmatch (NCT NCT00275509)

NCT ID: NCT00275509

Last Updated: 2018-01-18

Results Overview

Per 2007 international Banff Classification Criteria, CMR 1A was diagnosed on biopsies displaying significant interstitial infiltration (\>25% of parenchyma affected, i2 or i3) and foci of moderate tubulitis (t2). CMR IB was diagnosed in cases with significant interstitial infiltration (\>25% of parenchyma affected, i2 or i3) and foci of severe tubulitis (t3). CMR IIA were cases with mild-to-moderate intimal arteritis (v1), while CMR IIB were those with severe intimal arteritis comprising \>25% of the luminal area (v2). CMR III were those cases with transmural arteritis and/or arterial fibrinoid change and necrosis of medial smooth muscle cells with accompanying lymphocytic inflammation (v3).

PRIMARY outcome

Timeframe: Up to 6 months

Population: One patient in the Thymoglobulin arm died on post-operative day #8, prior to undergoing a biopsy. There were other deaths in the study however there were incidences of CMR, AMR or both prior to death.

Per 2007 international Banff Classification Criteria, CMR 1A was diagnosed on biopsies displaying significant interstitial infiltration (\>25% of parenchyma affected, i2 or i3) and foci of moderate tubulitis (t2).

PRIMARY outcome

Timeframe: Up to 6 months

Population: One patient in the Thymoglobulin arm died on post-operative day #8, prior to undergoing a biopsy. There were other deaths in the study however there were incidences of CMR, AMR or both prior to death.

A diagnosis of AMR was based on the 2013 international Banff Classification Criteria and is defined as the presence of circulating donor-specific antibody (DSA) and either: 1) peritubular capillary staining of C4d and at least one of the following: peritubular capillaritis (ptc) score\>0, glomerulitis (g) score\>0, acute thrombotic microangiopathy (TMA) in the absence of any other cause, or other features consistent with AMR (endothelial injury, fibrin thrombi, microinfarctions, interstitial hemorrhage), or 2) absence of capillary staining of C4d and the presence of ptc\>0 and g\>0 or ptc\>0 or g\>0 and acute TMA, in the absence of any other cause of TMA.
