What this trial studies

This clinical trial evaluates the efficacy and safety of ilofotase alfa, administered intravenously, in patients at risk for renal damage following open heart surgery. It is a Phase 2, multi-center, randomized, double-blind, placebo-controlled trial with two arms, where eligible patients will receive either ilofotase alfa or a placebo before and after their surgery. Participants will be monitored for efficacy, safety, and pharmacokinetics through daily follow-up visits for five days post-surgery, with additional assessments at Day 28 and Day 61. The study aims to determine if ilofotase alfa can effectively prevent renal complications in this high-risk population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older scheduled for specific types of open chest cardiovascular surgeries with a risk of renal damage.

Not a fit: Patients with body weight less than or equal to 55 kg or those with known or suspected glomerulonephritis may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence of kidney damage in patients undergoing open heart surgery.

How similar studies have performed: Other studies have explored similar interventions for preventing renal damage in surgical patients, but the specific use of ilofotase alfa in this context is novel.
