E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To determine the safety and pharmacokinetics of 800 mcg/kg intravenous (IV) infusions of
ABT-719 in the first 6 subjects enrolled who are at risk of acute kidney injury (AKI) and undergoing
high risk major surgery.
-To compare the safety and efficacy of doses of 800 mcg/kg, 1600 mcg/kg and 2100 mcg/kg
IV infusions of ABT-719 to placebo in subjects who are at risk of AKI and undergoing high risk major
surgery. |

• Proportion of subjects developing at least one of the composite events: death, needing RRT during the 60-day post-operative period, or having a ≥ 25% reduction in SCr based eGFR or measured GFR at Day 60 post-surgery visit
• Proportion of subjects developing at least one of the composite events: death, needing RRT during the 90-day post-operative period, or having a ≥ 25% reduction in S-Cystatin C based eGFR or measured GFR at Day 90 post-surgery visit
• Proportion of subjects developing at least one of the composite events: death, needing RRT during the 60-day post-operative period, or having a ≥ 25% reduction in S-Cystatin C based eGFR or measured GFR at Day 60 post-surgery visit
• Proportion of subjects developing AKI as defined by the RIFLE scoring criteria (Risk, Injury, Failure, Loss or ESRD)
• Proportion of subjects developing AKI as defined by the KDIGO scoring criteria (Stage 1, Stage 2 or Stage 3)
• Changes from baseline in serum creatinine (SCr) and S-Cystatin C at all study visits from Day 0 to Day 90
• Maximal change from baseline in SCr and S-Cystatin C until Day 7 or until discharge from the hospital
• Changes from baseline in SCr based eGFR, S-Cystatin C based eGFR and measured GFR at all study visits from Day 0 to Day 90
