Diabetes Mellitus
Conditions
Brief summary
This study will evaluate the safety, efficacy, and pharmacokinetics of MK-8521 given once daily compared to placebo and another diabetes drug in participants with Type 2 diabetes mellitus (T2DM). This study was modified by a protocol amendment to a 2-part trial to further test the safety and tolerability of MK-8521 at higher doses and to compare MK-8521 pharmacokinetics between participants with T2DM and healthy participants. An additional cohort of T2DM participants and a cohort of non-diabetic obese participants has been added.

Area Under the Concentration-time Curve From 0 to 24 Hours (AUC0-24hr) of MK-8521 on Days 1, 7, and 14 for Type 2 Diabetes Mellitus (T2DM) and Non-Diabetic Overweight/Obese Participants in Part 2
AUC0-24hr was the area under the concentration-time curve of MK-8521 from time zero to 24 hours after administration. Plasma samples were collected from predose to 24 hours postdose for determination of AUC0-24hr. Individual values were natural log-transformed and evaluated with a linear-mixed effects model containing fixed effects for treatment, day, and treatment by day interaction, and a random effect for participant. Kenward and Roger's method was used to calculate the degree of freedom for the fixed effects. AUC0-24hr is presented as geometric mean and percent coefficient of variation of geometric mean.

Change From Baseline in Peak Heart Rate (PHR) at Day 14 for Type 2 Diabetes Mellitus (T2DM) Participants in Part 2
PHR was defined as the maximum time matched baseline adjusted heart rate over 24 hours. Semi-recumbent PHR was measured in triplicate with at least a 1-2-minute interval between measurements at the following time points: baseline on Day 1; Day 14: predose, 2, 4, 6, 8, 12, and 16 hours postdose; and prior to dosing on Day 15. The repeated measurements were averaged before conducting the analysis. Change from baseline PHR was calculated as the peak heart rate at Day 14 minus baseline where baseline was defined as predose on Day 1.

Change from baseline RMHR was calculated as the RMHR 24 hours after the Day 7 dose (predose Day 8) minus baseline. Baseline was an average of 2 readings prior to dosing on Day 1.
Time frame: Baseline (predose Day 1) and Day 8 (24 hours after Day 7)
Population: The analysis population included a subset of participants who complied with the protocol sufficiently to ensure that their data exhibited the effects of treatment according to the underlying scientific model and had data available for the analysis of the endpoint. Per-protocol, non-diabetic overweight/obese participants were not planned for the analysis of resting morning heart rate.

Cmax was the maximum observed concentration of MK-8521 in plasma after administration on Day 14. Plasma samples were collected from predose to 120 hours postdose for determination of Cmax. Individual values were natural log-transformed and evaluated with a linear-mixed effects model containing fixed effects for treatment, day, and treatment by day interaction, and a random effect for participant. Kenward and Roger's method was used to calculate the degree of freedom for the fixed effects. Cmax is presented as geometric mean and percent coefficient of variation of geometric mean.

Number of Participants Discontinuing Study Drug Due to Adverse Events (AEs) in Part 1
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 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 (including an abnormal laboratory finding, for example), 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 (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. Discontinuations are presented by individual dose received by participants during titration in an assigned study treatment sequence.

Number of Participants Experiencing Adverse Events (AEs) in Part 1
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 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 (including an abnormal laboratory finding, for example), 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 (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. AEs are presented by individual dose received by participants during titration in an assigned study treatment sequence.
Time frame: Up to approximately 42 days
Population: The analysis population included all participants in Part 1 who received at least one dose of study drug.

The change from baseline value for 24-hour WMG was calculated where baseline was the WMG before food and prior to treatment on Day 1. Blood for plasma glucose concentrations was obtained at predose Day 1 at pre meal (breakfast), 0.5, 1, 2, 3, 4 (pre lunch), 4.5, 5, 6, 7, 10 (pre dinner), 10.5, 11, 12, 13, 15 and 23 hours post breakfast meal; and on Day 7 at 1 (pre breakfast), 1.5, 2, 3, 4, 5 (pre lunch), 5.5, 6, 7, 8, 11 (pre dinner), 11.5, 12, 13, 14, 16, 24 hours post dose. Individual change from baseline 24-hour WMG was analyzed in a linear mixed effects model with fixed effects for treatment, day and treatment by day interaction, a random effect for participant, and baseline 24-hour WMG as a covariate. WMG is presented as least squares mean with a 95% confidence interval.
Time frame: Baseline (predose and before food on Day 1) and up to 24 hours post Day 7 dose
Population: The analysis population included a subset of participants who complied with the protocol sufficiently to ensure that their data exhibited the effects of treatment according to the underlying scientific model and had data available for the analysis of the endpoint.

Maximum Concentration (Cmax) of MK-8521 for Type 2 Diabetes Mellitus (T2DM) and Non-Diabetic Overweight/Obese Participants in Part 2
Cmax was the maximum observed concentration of MK-8521 in plasma after administration. Plasma samples were collected from predose to 120 hours postdose for determination of Cmax. Per protocol, Cmax in the non-diabetic overweight/obese participants was not measured on Days 19, 24, and 29 because they only received 14 days of treatment. Individual values were natural log-transformed and evaluated with a linear-mixed effects model containing fixed effects for treatment, day, and treatment by day interaction, and a random effect for participant. Kenward and Roger's method was used to calculate the degree of freedom for the fixed effects. Cmax is presented as geometric mean and percent coefficient of variation of geometric mean.
