  Purpose
To evaluate cardio-renal and overall safety profile of GE 145 320 mg I/ml Injection when compared to iopamidol 370 mg I/mL. The study will focus on elderly subjects with either chronic renal insufficiency, or diabetes mellitus (DM) requiring drug therapy, or congestive heart failure (CHF) NYHA Class III or greater, who are referred for a coronary catheterization procedure with or without PCI.

Condition Intervention Phase
Cardio Renal Safety in High-risk Elderly Subjects Undergoing a Coronary CATH With or Without PCI. Drug: GE-145 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Diagnostic
Official Title: A Phase 2, Double-Blind, Randomized, Safety Study of GE-145 320 mg I/mL Injection Versus Iopamidol 370 mg I/mL in Elderly Subjects Undergoing Coronary Artery Catheterization Procedure

Primary Outcome Measures:
  • Comparison of Overall Image Quality Between Ioforminol and Iopamidol-enhanced Images as Determined by an Independent Reader. [ Time Frame: After the imaging date for either Ioforminol or Iopamidol. ]
    Overall image quality (excellent, adequate or poor) and diagnostic usefulness (diagnostic or non-diagnostic) were assessed using qualitative scales.


Secondary Outcome Measures:
  • To Determine Incidence Rates of the Overall AEs, Organ-specific AEs (i.e., Delayed Skin Reactions, General Subject Comfort, and Allergic/Immunologic Reactions, Etc.) and SAEs Following Administration [ Time Frame: Time zero equals the date of contrast imaging and for up to 7 days for safety monitoring post contrast administration. ]

    To determine incidence rates of the overall AEs, organ-specific AEs (i.e., delayed skin reactions, general subject comfort, and allergic/immunologic reactions, etc.) and SAEs following administration of GE-145 or iopamidol.

    To determine incidence rates and onset time of biomarker-based and SCr-based CI-AKI following administration of GE-145 or iopamidol.

    Summary of Treatment-Emergent Adverse Events (TEAE) in greater than of equal to 2% of Subjects.


  • Assessing the Incidence of Renal Biomarker-based Contrast-induced Acute Kidney Injury (CI-AKI) in Subjects Post Administration of Ioforminol or Iopamidol Injections [ Time Frame: 2, 6 and 24 hours post Ioforminol and Iopamidol adminstration ]
    Analyzing the number of subjects with renal biomarker-based contrast-induced acute kidney injury (CI-AKI).
