Study Overview

Brief Summary

The goal of the study is to learn what happens to different doses and forms of TERN-701 in a healthy person's body over time. Researchers will compare what happens to different doses and forms of TERN-701 in a person's body over time when given with or without food, or with or without other medications.

The goal of the study is to learn:

  • What happens to different doses of TERN-701 in a person's body over time when it is given with or without food, or with or without other medications.
  • About the safety of TERN-701 and if people tolerate it

Detailed Description

Per protocol, participants will be randomized in Cohort 7 to the sequence in which they receive two TERN-701 formulations. All other cohorts will be non-randomized.
