Trial design

The placebo is identical with the IMP, but without active substance (placebo comparator; no dose/schedule specified for placebo beyond being identical to IMP without active substance).-controlled, adaptive Phase III trial across 7 sites in Belgium, Austria.

Comparator
The placebo is identical with the IMP, but without active substance (placebo comparator; no dose/schedule specified for placebo beyond being identical to IMP without active substance).
Adaptive
True (stopping rules specified: stop administering placebo but continue experimental drug if AKI or mortality significantly lower in experimental group; stop if all-cause mortality, cardiac mortality, AKI, or primary compound outcome significantly higher in experimental group; stop if >5% of patients have a serious adverse/allergic reaction).

Endpoints

Primary endpoints

  • {"endpoint_text":"- • Stop administering placebo but continue with experimental drug if AKI (defined by AKIN) is significantly lower in the experimental group or mortality is significantly lower in the experimental group.","definition_or_measurement_approach":"AKI defined by AKIN criteria (rise in serum creatinine by 0.3 mg/dl or 26 μmol/L in 48 hours or ≥50% increase in serum creatinine, or urine output < 0.5 ml/kg/hour for 6 hours). AKI occurrence checked within 30 days and additionally after 90 days after surgery. (As described in main objective.)"}
  • {"endpoint_text":"- • Stop if all cause mortality, cardiac mortality, acute kidney injury, or the primary compound outcome is significantly higher in the experimental group","definition_or_measurement_approach":"All-cause and cardiac mortality assessed post-surgery; acute kidney injury assessed per AKIN criteria (see above).
