Relative Bioavailability of CE-Iohexol (Captisol-enabled™ Iohexol) Injection and Omnipaque™ Injection

Contrast-induced Nephropathy Clinical Trial

Official title: A Randomized, Double-Blind, 2-Period Crossover Trial to Determine the Relative Bioavailability of CE-Iohexol (Iohexol/Sulfobutylether-β-Cyclodextrin ( Captisol®)) Injection and Omnipaque™ (Iohexol) Injection in Healthy Adult Volunteers

Status Completed

Clinical Trial Summary

This study is designed to compare the bioavailability of the test Product(CE-Iohexol Injection) and the reference product Iohexol Injection (Omnipaque™) following intravenous injection in normal healthy volunteers. The secondary objective is to assess the safety and tolerability of the treatments administered. Captisol® is present to improve stability and to potentially reduce the risk of contrast-induced acute kidney injury(CI-AKI) associated with iohexol administration.

Clinical Trial Description

This is a single center, randomized, double-blind, 2-period, crossover study. A total of 24 subjects will be enrolled in the study; subjects will be dosed as 2 groups of 12 subjects each. Additional subjects may be enrolled into the study to obtain the statistical power of 90%. Subjects will attend a screening visit within 28 days prior to Period 1, and eligible subjects will then return to the clinic on the evening prior to Day -1. On Day 1, prior to dosing, subjects will be randomized to receive either CE-Iohexol Injection or the reference product during the first treatment period and the alternate product during the second treatment period. In each period, the study drug will be administered after a fasting period ≥8 hours. Each dose of intravenous iohexol will be separated by a minimum of a 7-day washout period. The test or reference product (iohexol 350 mg Iodine/mL, 80 mL) will be infused at a high flow rate of 4 mL/second for a dose of 400 mgI/kg for 70 kg subject. The test or reference product will be administered using a power injector. Plasma samples for determination of iohexol concentrations will be obtained from arm #2 (the arm not used for dosing) at 0 (pre-dose), 30 seconds, 5, 10, 15, 20, 30 and 45 minutes, and 1, 2, 3, 4, 6, 8, 12, 24, and 48 hours after infusion start; the 30-second sample obtained at the end of infusion. Subjects will be discharged from the clinic on Day 3 following collection of the 48-hour blood sample. ;
