A Study to Assess Pharmacokinetics (PK) of Preladenant in Participants With Chronic Renal Impairment (CRI) (P06512)

September 1, 2018 updated by: Merck Sharp & Dohme LLC

A Study to Assess Pharmacokinetics of Preladenant in Subjects With Chronic Renal Impairment

This is a two part study to compare the PK of preladenant administered to participants with CRI to the PK of preladenant administered to healthy participants. Part 1 will compare the PK of participants with severe CRI to healthy participants. Part 2 will compare the PK of participants with moderate CRI and participants with mild CRI to healthy participants. The primary hypotheses are that the plasma area under the concentration-time curve from time 0 to infinity after single dosing (AUC0-∞) of preladenant in participants with either severe, moderate or mild CRI is similar to that of matched healthy participants.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All
