Pharmacokinetics (PK) and Safety of a Single Intravenous (IV) Dose of MK-3866 in Participants With Impaired Renal Function and in Healthy Controls (MK-3866-005)

Merck Sharp & Dohme LLC42 enrolled

Overview

The purpose of this study is to compare plasma and urine PK parameters of MK-3866 between participants with impaired renal function and healthy control participants, to investigate the extent to which MK-3866 is removed from the plasma by hemodialysis (HD), and evaluate the safety and tolerability of MK-3866 in participants with impaired renal function.

This is an open-label, 2-part single dose study: Part 1 will include participants with mild, moderate, and severe renal impairment (as well as healthy control participants), and Part 2 will include participants with end stage renal disease (ESRD) undergoing HD. Participants in Part 1 will receive a single IV dose of MK-3866, and plasma and urine samples will be collected over pre-specified time intervals. Participants in Part 2 will receive a single IV dose of MK-3866 on two separate occasions: in Period 1 immediately following their normally-scheduled HD, and in Period 2 approximately 30 minutes prior to their normally-scheduled HD. Plasma, urine, and dialysate samples will be collected over pre-specified time intervals for Part 2.

Number of Participants With at Least One Adverse Event (AE)

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
