Summary

The purpose of this trial is to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GRT7041 in healthy male and female (Women of non-childbearing potential) participants. The trial duration will be up to approximately 6 weeks for participants in Part 1 (Single ascending dose \[SAD\]), except for participants taking part in the food effect cohort SAD3 where the trial duration will be up to approximately 8 weeks.

  • The participant is enrolled in another clinical trial unless it is an observational (non-interventional) clinical trial or during the follow-up period of an interventional trial) or has received an IMP in another clinical trial within 30 days before Day 1 or within 5 times the elimination half-life of the IMP, whichever is longer.
