Evaluation of RenalGuard® System to Reduce the Incidence of Contrast Induced Nephropathy in At-Risk Patients (CIN-RG)

This study is currently recruiting participants. (see Contacts and Locations)

Contrast-Induced Nephropathy (CIN) can occur when patients with pre-existing kidney problems undergo procedures that use iodinated contrast media, such as cardiac catheterizations. RenalGuard Therapy was developed to enable the patient to clear the contrast out of their kidney before it can do significant damage. This study aims to enroll patients with increased risk of developing CIN who are scheduled for a cardiovascular catheterization. Patients will be randomized to either RenalGuard therapy or standard therapy.

Condition Intervention Phase
Contrast Induced Nephropathy
Device: RenalGuard Therapy
Drug: Standard Therapy
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Masking: No masking
Primary Purpose: Prevention
Official Title: A Study to Evaluate RenalGuard® System Safety & Efficacy When Compared With Standard Care in the Prevention of Contrast Induced NephRopathy in the SettinG of a Catheterization Laboratory
