[¹⁴C]Enlicitide chlorideEXPERIMENTALParticipants will receive a single dose of \[¹⁴C\]enlicitide chloride on Day 1.
Enlicitide Chloride Panel AEXPERIMENTALPeriod 1: Participants will receive a single dose of enlicitide chloride dose 1 or a single dose of placebo on Day 1 on an empty stomach (after a ≥8-hour overnight fast). Period 2: Participants will receive a single dose of enlicitide chloride dose 1 or a single dose of placebo on Day 1 on an empty stomach (after a ≥8-hour overnight fast) followed by a standard breakfast.
Enlicitide Chloride Panel BEXPERIMENTALPeriod 1: Participants will receive a single dose of enlicitide chloride dose 2 or a single dose of placebo on Day 1 on an empty stomach (after a ≥8-hour overnight fast). Period 2: Participants will receive a single dose of enlicitide chloride dose 3 or a single dose of placebo on Day 1 on an empty stomach (after a ≥8-hour overnight fast).
Enlicitide Chloride Panel CEXPERIMENTALParticipants will receive enlicitide chloride dose 2 or placebo once daily for 14 days on an empty stomach (after a ≥8-hour overnight fast).
Enlicitide ChlorideEXPERIMENTALParticipants receive enlicitide chloride titrated orally from Dose 1, Dose 2, or Dose 3 once daily (QD) over the course of a 14-day treatment for each dose based on the safety and tolerability of the previous starting dose.
