A Trial to Assess the Effect of Kidney Impairment on How AMG 133 is Absorbed, Broken Down, and Eliminated by the Body

Completed · Phase 1

Conditions studied: Overweight and Obesity

In brief

The primary objective of this trial is to evaluate the pharmacokinetics of a single subcutaneous (SC) dose of AMG 133 in participants with various degrees of renal impairment compared to participants with normal renal function.
