A Clinical Trial of Multiple Formulations of MK-4082 in Healthy Overweight and Obese Participants (MK-4082-007)

Researchers are looking for new weight loss medicines for people with higher body weight. The study medicine, MK-4082, is different from similar weight loss medicines because people take it as a pill instead of an injection. Before giving a study medicine to people with a health condition, researchers first do studies to find a safe dose level (amount) and formulation (version) of the study medicine that can be used in future studies.

The goals of this study are to learn about:

The safety of different formulations of MK-4082 and if people tolerate them What happens to different formulations of MK-4082 in a person's body over time

Primary outcomes

  1. Number of Participants Who Experience an Adverse Event (AE)

    Time frame: Up to approximately 8 weeks

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who experience an AE will be reported.

  2. Number of Participants Who Discontinue Study Treatment Due to an AE

    Time frame: Up to approximately 6 weeks

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who discontinue study treatment due to an AE will be reported.

Secondary outcomes

  1. Area Under the Curve from Time 0 to 24 hours (AUC0-24) of MK-4082

    Time frame: At designated timepoints (up to 24 hours postdose)

    Blood samples will be collected to determine the AUC0-24 of MK-4082.

  2. Plasma Concentration at 24 Hours (C24) of MK-4082

    Time frame: At designated timepoints up to 24 hours postdose

    Blood samples will be collected to determine the C24 of MK-4082.
