Detaljerad beskrivning
This is a Phase 2, multi-center, randomized, double-blind, placebo-controlled, 2-arm parallel group design trial in patients at risk for renal damage following open heart surgery. After screening and baseline assessments, eligible patients will be randomized 1:1 to either 2 doses of 128 mg ilofotase alfa, or 2 doses of placebo control. Randomization will be stratified by baseline eGFR and type of surgery. The patient will be treated with the investigational product (ilofotase alfa or placebo) at the same day before and after the surgery (Day 1). Follow-up clinic visits will be performed daily up to Day 5 for efficacy, safety, and pharmocokinetics assessments. A safety follow-up can be performed by telephone at Day 28. At Day 61, an end of trial visit will be done at site for efficacy, safety, and anti-drug antibodies assessments.

Serum Creatinine Level Ratio
Tidsram: From Baseline (Day -1/1) to Day 5
|
Ratio between the highest serum creatinine value post-surgery (post-surgery Day 1 and Days 2, 3, 4, and 5) and baseline serum creatinine (pre-surgery, Day -1/Day 1). The values at post-surgery Day 1 and Days 2, 3, 4, and 5 compared to the value at baseline (Day -1/Day 1) are used to calculate the serum creatinine ratio. The reported means and standard deviations are based on patient-level ratios and include observed and imputed values. |

Assessment of Major Adverse Kidney Events (MAKE) 60
Tidsram: 60 days
|
Major adverse kidney events (MAKE) 60, defined as died up to and including Day 61, have received or are receiving new renal replacement therapy (RRT) up to and including Day 61, or have a decrease in estimated glomerular filtration rate (eGFR) ≥25% on Day 61 compared to the pre-surgery baseline eGFR reference value. With Day 1 being the day of surgery. |

Cumulative AKI Severity (Area Under the Curve)
Tidsram: From Day 1 to Day 5
|
Area under the curve of daily AKI severity stage/grade (0-3) from Day 1 to Day 5; higher values indicate greater cumulative AKI severity |
