8. Serum creatinine \> 2.0 mg/dL or 177 μmol/L or creatinine clearance \< 40 mL/min (using the Cockcroft-Gault formula below): Female = \[(140 - age in years) × weight in kg × 0.85\] / \[72 × serum creatinine in mg/dL\] Male = \[(140 - age in years) × weight in kg × 1.00\] / \[72 × serum creatinine in mg/dL\]
8. Have any of following:
1. Cirrhosis at a level of Child-Pugh B (or worse);
2. Cirrhosis (any degree) and a history of hepatic encephalopathy; or
3. Clinically meaningful ascites resulting from cirrhosis. Clinically meaningful ascites is defined as ascites from cirrhosis requiring diuretics or paracentesis.
