Brief Summary:
The purpose of this research study is to compare the effectiveness of intravenous isotonic sodium bicarbonate with intravenous isotonic sodium chloride and oral N-acetylcysteine (NAC) with oral placebo for the prevention of serious adverse outcomes following angiographic procedures in high-risk patients.

Condition or disease Intervention/treatment Phase
Acute Renal Failure Kidney Disease Coronary Artery Disease Drug: IV isotonic saline Drug: IV isotonic bicarbonate Drug: N-acetylcysteine Drug: Placebo Phase 3

Detailed Description:
The intravascular administration of iodinated contrast media for diagnostic imaging is a common cause of acute kidney injury (AKI) and a leading cause of iatrogenic renal disease. Contrast-induced AKI is associated with serious adverse outcomes including death, need for dialysis, prolonged hospitalization, and acceleration in the rate of progression of underlying chronic kidney disease. The benefit of IV isotonic bicarbonate compared to IV isotonic saline and of N-acetylcysteine for the prevention of contrast-induced AKI and associated adverse outcomes remains unclear. The purpose of this trial is to compare the effectiveness of IV isotonic sodium bicarbonate with IV isotonic sodium chloride and oral NAC with placebo for the prevention of serious adverse outcomes in 7,680 high-risk patients scheduled to undergo coronary or non-coronary angiography. Using a 2 x 2 factorial design, patients will be randomized to receive: 1) either peri-procedural IV isotonic sodium bicarbonate or peri-procedural IV isotonic saline and 2) either oral NAC or oral placebo prior to and for 5 days following the angiographic procedure. The primary study endpoint is a composite outcome comprised of death, need for acute dialysis, or persistent decline in kidney function within 90 days following the index angiogram.

Outcome Measures
Go to

Primary Outcome Measures :
  1. Number of Participants With Serious, Adverse, Patient-Centered Events, Including Death, Need for Acute Dialysis, or Persistent Decline in Kidney Function, Comparing Intravenous Sodium Bicarbonate With Intravenous Sodium Chloride. [ Time Frame: Within 90 days following angiography ]
    Death will be based on medical record and/or vital status registry documentation Need for acute dialysis will be defined as the initiation of any modality of renal replacement (intermittent hemodialysis, peritoneal dialysis, continuous renal replacement therapy, or sustained low-efficiency dialysis) Persistent decline in kidney function will be defined as an increase in serum creatinine of at least 50% from the baseline value collected pre-angiography to the measurement taken 90 days following the angiography.

  2. Number of Participants With Serious, Adverse, Patient-Centered Events, Including Death, Need for Acute Dialysis, or Persistent Decline in Kidney Function, Comparing Oral N-Acetylcysteine With Oral Placebo. [ Time Frame: Within 90 days following angiography ]
    Death will be based on medical record and/or vital status registry documentation Need for acute dialysis will be defined as the initiation of any modality of renal replacement (intermittent hemodialysis, peritoneal dialysis, continuous renal replacement therapy, or sustained low-efficiency dialysis) Persistent decline in kidney function will be defined as an increase in serum creatinine of at least 50% from the baseline value collected pre-angiography to the measurement taken 90 days following the angiography.
