Randomized Trial of Induction Therapies in High Immunological Risk Kidney Transplant Recipients

Phase 4

Completed

Conditions: Kidney Transplantation

Interventions: Drug: Rabbit Antithymocyte Globulin
Drug: Velcade
Drug: Rituxan

Registration Number: NCT00782821

Lead Sponsor: University of Cincinnati

Brief Summary: The purpose of this research study is to find out the effects of adding B lymphocyte modulating agents in patients at risk for rejection receiving an anti-rejection (immunosuppressive) regimen of Thymoglobulin® induction with Prograf®, Cellcept® and corticosteroid therapy.

Detailed Description: Optimal induction regimens for patients at high risk for antibody and/or cell-mediated rejection have not been established. This pilot, prospective, randomized study evaluated addition of B cell/plasma cell-targeting agents to T cell-based induction with rabbit antithymocyte globulin (rATG) in high immunologic risk renal transplant recipients. Patients were randomized to induction with rATG, rATGþrituximab, rATGþbortezomib or rATGþrituximabþbortezomib.

Primary Outcome Measures

Name	Time	Method
Incidence of Acute Rejection (Banff '97) or Antibody Mediated Rejection	6 months	Antibody mediated rejection demonstrated to be due to, atleast in part, to anti-donor antibody at 6 months by Banff 97' criteria. Acute rejection IA - cases with significant interstitial infiltration (\>25% of parenchyma affected) and foci of moderate tubulitis (\>4 mononuclear cells/tubular cross section or group of 10 tubular cells). IB - cases with significant interstitial infiltration (\>25% of parenchyma affected) and foci of severe tubulitis (\>10 mononuclear cells/tubular cross section or group of 10 tubular cells) IIA - cases with mild to moderate intimal arteritis (v1) IIB - cases with server intimal arteritis comprising \>25% of the luminal area (v2) III - case with transmural arteritis and/or arterial fibrinoid change and necrosis of medical smooth muscle cells (v3 with accompanying lymphoctic inflammation)

Secondary Outcome Measures

Name	Time	Method
Acute Cellular Rejection by Banff '97 Criteria (Updated 2005)	6 months	Acute cellular rejection IA - cases with significant interstitial infiltration (\>25% of parenchyma affected) and foci of moderate tubulitis (\>4 mononuclear cells/tubular cross section or group of 10 tubular cells). IB - cases with significant interstitial infiltration (\>25% of parenchyma affected) and foci of severe tubulitis (\>10 mononuclear cells/tubular cross section or group of 10 tubular cells) IIA - cases with mild to moderate intimal arteritis (v1) IIB - cases with server intimal arteritis comprising \>25% of the luminal area (v2) III - case with transmural arteritis and/or arterial fibrinoid change and necrosis of medical smooth muscle cells (v3 with accompanying lymphoctic inflammation)
Patient Allograft Survival at 12 Months	12 months	Patient's allograft was still functioning at 12 months post study enrollment
Antibody-mediated Rejection by Banff '97 Criteria (Updated 2005)	6 months	Antibody mediated rejection demonstrated to be due to, atleast in part, to anti-donor antibody at 6 months by Banff 97' criteria. Rejection due, at least in part, to documented anti-donor antibody ('suspicious for' if antibody not demonstrated); may coincide with categories 3, 4 and 5. Grade I. ATN-like - C4d+, minimal inflammation Grade II. Capillary- margination and/or thromboses, C4d+ Grade III. Arterial - v3, C4d+
Patient Survival at 12 Months	12 months	Patient was still alive 12 months post study enrollment.
