Summary

Iodinated contrast media have been causally linked to acute kidney injury known as contrast-induced nephropathy (CIN), which is the consequence of CM-induced local renal ischemia and direct toxic effects. Conestat alfa (recombinant human C1 esterase inhibitor) has been shown to decrease renal ischemic damage in experimental models of renal ischemia.

The Recombinant Human C1 Esterase Inhibitor in the Prevention of Contrast-induced Nephropathy in High-risk Subjects (PROTECT) Study is a randomized, placebo-controlled, double-blind single-center trial that will assess the effect of prophylactic administration of Conestat alfa on the degree of acute kidney injury subjects undergoing elective coronary angiography. Patient with an estimated glomerular filtration rate \<=50 ml/min/1.73 m2 and at least one additional risk factor for CIN will be enrolled and randomly assigned to 1) Conestat alfa at 50 U/kg given as intravenous injection immediately before and 4 hours after coronary angiography or 2) placebo (sodium chloride). All patients will receive standard intravenous hydration with isotonic saline. Surrogate markers of kidney injury will be assessed over a 48 hours time period. Patients will be followed for cardiovascular and renal events over 12 weeks.

The primary outcome measure is peak change in urinary Neutrophil gelatinase-associated lipocalin within 48 hours after elective coronary angiography.

Conditions

Interventions

DRUG

Conestat alfa

Two intravenous injections (over 5 minutes) of Conestat alfa immediately pre-procedure (elective coronary angiography) and 4 hours later; for patients less than 84kg at a dose of 50 U/kg, and for patients of 84kg body weight or greater at a dose of 4200 U.

DRUG

Sodium chloride 0.9%

Two intravenous injections of sodium chloride 0.9% (maximum 28 ml, matching the respective amount of the Conestat alfa arm) immediately pre-procedure (elective coronary angiography) and 4 hours later.
