A Clinical Trial in Healthy Participants to Learn How Itraconazole Affects MK-2828 Levels and How MK-2828 Affects Midazolam Levels (MK-2828-007)

A Phase 1 interventional study of MK-2828 and Itraconazole in Healthy, sponsored by Merck Sharp & Dohme LLC. Completed at 1 site in United States. Open to participants aged 24 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-08.

Study summary

The main goals of this study are:

  • To learn what happens to one dose of MK-2828 in a healthy person's body over time when it is taken with itraconzole
  • To learn what happens to one dose of midazolam in a healthy person's body over time when it is taken with MK-2828

Researchers want to learn if the levels of MK-2828 in the body are about the same when MK-2828 is taken with itraconazole as when it is taken alone. They also want to know if taking MK-2828 more than once affects how much midazolam is in the body after a single dose.
