Trial Outcomes & Findings for Renal Effects of Two Iodinated Contrast Media in Patients at Risk Undergoing Computed Tomography (NCT NCT00209417)

NCT ID: NCT00209417

Last Updated: 2014-10-17

Results Overview

The primary endpoint was the incidence rate of CIN, defined as an intra-individual increase in serum creatinine (SCr) of greater than or equal to 44.2 µmol/L (greater than or equal to 0.5 mg/dL). Subjects with a pre-contrast (baseline) serum creatinine value greater than or equal to 1.5 mg/dL for males and greater than or equal to 1.3 mg/dL for females or eGFR of less than or equal to 50 mL/min/1.73m squared, and a post-contrast serum creatinine value available on days 2 or 3, administered greater than or equal to100 mL or greater than or equal to 1.5 mL/kg bodyweight IMP, without presence of any major protocol violations, and without evidence of other causes inducing acute renal dysfunction.

Participant Flow

656 subjects enrolled. 8 subjects did not continue on in the study. 7 of the 8 subjects discontinued the study prior to contrast media administration and 1 of the 8 subjects received a contrast media of unknown type and was excluded from the study. Subtracting 8 subjects from the total 656, a total of 648 subjects actually completed the study.

PRIMARY outcome

Timeframe: From baseline up to 3 days post contrast administration.

Population: To calculate the incidence rate of CIN, divide the number of subjects affected by the total number of subjects dosed in each treatment group.

The primary endpoint was the incidence rate of CIN, defined as an intra-individual increase in serum creatinine (SCr) of greater than or equal to 44.2 µmol/L (greater than or equal to 0.5 mg/dL). Subjects with a pre-contrast (baseline) serum creatinine value greater than or equal to 1.5 mg/dL for males and greater than or equal to 1.3 mg/dL for females or eGFR of less than or equal to 50 mL/min/1.73m squared, and a post-contrast serum creatinine value available on days 2 or 3, administered greater than or equal to100 mL or greater than or equal to 1.5 mL/kg bodyweight IMP, without presence of any major protocol violations, and without evidence of other causes inducing acute renal dysfunction.
