During transplant surgery, there is a period of time when a donated kidney is removed from a donor's body and stored until the time of the transplant surgery. The storage procedure results in buildup of various proteins within the kidney that can injure the donated kidney after it is transplanted. One of these proteins is tumor necrosis factor-alpha (TNF-alpha). The purpose of this study is to evaluate whether taking infliximab, which blocks tumor necrosis factor alpha (TNF-alpha), just prior to transplant surgery, along with usual transplant medicines will protect the donated kidney from damage caused by TNF-alpha and help keep the transplanted kidney healthy for a longer period of time.
This is a Phase 2, multicenter, randomized, double blind (masked), placebo-controlled, 2-arm clinical trial of 300 deceased donor kidney transplant recipients. Participants will be randomized (1:1) to the experimental or control arm (150 subjects per arm).

The Difference Between the Mean eGFR (Modified MDRD) in the Experimental vs. Control Groups.
Glomerular filtration rate (GFR) is a measure of kidney function and helps determine the stage of kidney disease. eGFR was estimated using the Modification of Diet in Renal Disease (MDRD) equation. A value of 90+ means kidney function is normal. A value between 60 and 89 indicates mildly reduced kidney function, pointing to kidney disease. Values between 30 and 59 indicates moderately reduced kidney function. Values between 15 and 29 indicate severely reduced kidney function. Values below 15 indicate very severe or endstage kidney failure. eGFR values from months 1, 3, 6, 12, 18, and 24 were used to generate an estimate of the month 24 eGFR for each treatment group.
Time frame: 24-Month post-transplantation

Percent of Participants With BANFF Chronicity Scores > or Equal 2 on the 24 Month Biopsy.
The Banff 2013 classification involves scoring numerous characteristics of renal biopsy specimens. The ci (interstitial fibrosis) and ct (tubular atrophy) scores are two such characteristics. The scores can take values of 0, 1, 2, or 3 for each characteristic (ci and ct), indicating increasing severity of disease as the scores increase. Participants are considered to have met this endpoint if their ci + ct score on the 24 month biopsy summed to be \> or equal to 2.

Serum creatinine (mg/dL) is used to measure kidney function. A normal result is 0.7 to 1.3 mg/dL for men and 0.6 to 1.1 mg/dL for women. Higher results indicate poorer kidney function, as creatinine is removed from the body by the kidneys. eGFR values from 24, 48, and 72 hours post-transplant (i.e., days 1, 2, and 3) were used to generate an estimate of the serum creatinine at each time point of interest for each treatment group.
