Renal function was assessed by predicting the patient's creatinine clearance (CLcr), as described by Cockcroft and Gault [32]. *Normal renal function was defined as a predicted CLcr >80 ml/min. Mild renal impairment was defined as a predicted CLcr of 50–80 ml/min. ITT, intent to treat population; SD, standard deviation; SP, safety population.
