Healthy volunteers: no

Brief summary:
The purpose of this study is to compare the safety and efficacy of carfilzomib, including measuring the amount of the study drug in the blood at certain times following dosing. This study is being done in people with varying degrees of liver function to see if they respond differently to the study drug.

Detailed description:

Arms:
arm 1: Participants with normal hepatic function (bilirubin and aspartate aminotransferase (AST) ≤ the upper limit of normal (ULN)) received carfilzomib 20 mg/m² administered by intravenous (IV) infusion on days 1 and 2 of cycle 1, followed by a planned step-up to 27 mg/m² IV on days 8, 9, 15, and 16 of cycle 1. Participants who adequately tolerated dosing at 27 mg/m² in cycle 1 received carfilzomib 56 mg/m² IV on days 1, 2, 8, 9, 15, and 16 of cycle 2 and subsequent 28-day cycles until confirmed progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death. arm 2: Participants with mild hepatic impairment (bilirubin \> 1-1.5 x ULN or AST \> ULN, but bilirubin ≤ ULN) received carfilzomib 20 mg/m² administered by intravenous (IV) infusion on days 1 and 2 of cycle 1, followed by a planned step-up to 27 mg/m² IV on days 8, 9, 15, and 16 of cycle 1. Participants who adequately tolerated dosing at 27 mg/m² in cycle 1 received carfilzomib 56 mg/m² IV on days 1, 2, 8, 9, 15, and 16 of cycle 2 and subsequent 28-day cycles until confirmed progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death. arm 3: Participants with moderate hepatic impairment (bilirubin \> 1.5-3 x ULN, any AST) received carfilzomib 20 mg/m² administered by intravenous (IV) infusion on days 1 and 2 of cycle 1, followed by a planned step-up to 27 mg/m² IV on days 8, 9, 15, and 16 of cycle 1. Participants who adequately tolerated dosing at 27 mg/m² in cycle 1 received carfilzomib 56 mg/m² IV on days 1, 2, 8, 9, 15, and 16 of cycle 2 and subsequent 28-day cycles until confirmed progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death. arm 4: (Bilirubin \> 3 × ULN; any AST) Participants with severe hepatic impairment (bilirubin \> 3 x ULN; any AST) received carfilzomib 20 mg/m² administered by intravenous (IV) infusion on days 1 and 2 of cycle 1, followed by a planned step-up to 27 mg/m² IV on days 8, 9, 15, and 16 of cycle 1. Participants who adequately tolerated dosing at 27 mg/m² in cycle 1 received carfilzomib 56 mg/m² IV on days 1, 2, 8, 9, 15, and 16 of cycle 2 and subsequent 28-day cycles until confirmed progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death.
