A Study of The Effect of Hepatic Impairment on The Pharmacokinetics of Aleglitazar

The Effect of Hepatic Impairment on the Pharmacokinetics of Aleglitazar: A Multiple-centre, Open-label Study Following a Single Oral Dose of Aleglitazar to Subjects With Mild or Moderate Hepatic Impairment and Healthy Subjects With Normal Hepatic Function.

This open-label study will assess the effects of hepatic impairment on the pharmacokinetics of a single oral dose of aleglitazar in subjects with mild or moderate hepatic impairment (Child-Pugh class A or B) and in matched control subjects with normal hepatic function. Subjects will receive a single oral dose of aleglitazar, with assessment of the pharmacokinetics of aleglitazar on Days 1-5. Anticipated duration of study for each enrolled subject is approximately 6 weeks.
