The aim of this study is to examine the relative bioavailability of elinzanetant when administered in new oral formulations (treatment B and C) after both single and multiple oral doses, compared to its administration in soft gel capsule form (treatment A).
Study details include:
An ambulatory screening visit within 4 weeks prior to first treatment. Participants will be admitted to the ward on Day -1 of each period. On Day 1, either treatment B or treatment C will be administered fasted in the evening, followed by blood sampling for a 24-hour pharmacokinetic (PK) profile.
On Day 2, the multiple dosing starts 3 hours after a standardized dinner in the evening.
After the last dosing on Day 7, a complete PK profile for 24 hours will be collected.
If there are no medical objections, participants will be discharged from the study ward on Day 9 in the morning for a washout-out period of at least 10 days (240 hours after last dosing, after period 1 and 2) or, in period 3, after the follow-up examination.
The total duration of the study will be approximately 10 to 12 weeks for each participant.
