What is being measured
The primary outcome is the main question the study is designed to answer.
Area Under the Concentration Versus Time Curve From Time 0 to Last Quantifiable Sample (AUC0-last) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the AUC0-last of MK-8527 in participant's plasma. AUC0 to last of MK-8527 was defined as the area under the concentration-time curve from time 0 to the time of the last quantifiable (above lower limit of quantitation) concentration. AUC0-last was calculated using noncompartmental analysis.
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Area Under the Concentration Versus Time Curve From Time 0 to Infinity (AUC0-inf) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the AUC0-inf of MK-8527 in participant's plasma. AUC0-inf was defined as AUC0-last + (Cest,last/λz) where Cest,last was the estimated last measurable concentration, and λz was the apparent first-order terminal elimination rate constant.
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Maximum Concentration (Cmax) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the Cmax of MK-8527 in participant's plasma. Cmax was defined as the maximum observed concentration of MK-8527 in plasma after the administration of a given dose.
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Time to Maximum Concentration (Tmax) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the tmax of MK-8527 in participant's plasma. Tmax of MK-8527 in plasma was determined by deriving the difference between the time of the blood draw associated with the Cmax and the time of study drug administration
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Apparent Terminal Half-life (t1/2) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the t1/2 of MK-8527 in participant's plasma. t1/2 was defined as 0.693/Apparent terminal elimination rate constant (λz).
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Apparent Clearance (CL/F) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the CL/F of MK-8527 in participant's plasma. CL/F was defined as dose/(AUC0-inf).
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose
Apparent Volume of Distribution During Terminal Phase (Vz/F) of MK-8527 in Plasma
Blood samples were collected at pre-specified time points to determine the Vz/F of MK-8527 in participant's plasma. Vz/F of MK-8527 in plasma was determined using the formula Dose/(AUC0-inf × λz).
Measured: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose

Measured: 168 hours post dose
Concentration at 672 Hours (C672) of MK-8527-TP in PBMCs in Participants With Moderate and Severe Renal Impairment
Blood samples were collected at pre-specified time points to determine the C672 of MK-8527-TP, the active triphosphate anabolite of MK-8527, in participant's PBMCs. Geometric mean of C672 of MK-8527-TP in PBMCs was determined.
Measured: 672 hours post dose

Blood samples were collected at pre-specified time points to determine the C672 of MK-8527-TP, the active triphosphate anabolite of MK-8527, in participant's PBMCs. Since ≤ 50% of healthy participants had BLQ values, the BLQ value was set to zero and the median, minimum, and maximum was reported for C672.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing MK-8527 in people with Renal Impairment, run by Merck Sharp & Dohme LLC at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Feb 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Concentration Versus Time Curve From Time 0 to Last Quantifiable Sample (AUC0-last) of MK-8527 in Plasma (time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, and 168 hours post dose). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2026.
