Imlunestrant + Repaglinide (Cohort 1)
Participants received: Day 1: A single oral dose of 0.5 mg repaglinide administered alone. Day 3: A single oral dose of 800 mg imlunestrant, followed approximately 2 hours later by 0.5 mg repaglinide, both administered orally.
Imlunestrant + Omeprazole & Dextromethorphan (Cohort 2)
Participants received: Day 1: A single oral dose of 20 mg omeprazole and 30 mg dextromethorphan, administered in the morning. Day 3: A single oral dose of 800 mg imlunestrant, followed immediately by 20 mg omeprazole and 30 mg dextromethorphan, all administered orally.
Imlunestrant + Quinidine (Cohort 3)
Participants received: Day 1: A single oral dose of 400 mg imlunestrant, administered in the morning. Days 15 to 17 and 19 to 24: Twice-daily oral doses of 200 mg quinidine, administered alone. Day 18: A single oral dose of 400 mg imlunestrant administered in combination with 200 mg quinidine (quinidine was dosed twice on this day as part of the regular regimen).
Imlunestrant + Rosuvastatin & Digoxin (Cohort 4)
Participants received: Day 1: A single oral dose of 10 mg rosuvastatin and 0.25 mg digoxin, administered in the morning. Day 10: A single oral dose of 400 mg imlunestrant, administered in combination with 10 mg rosuvastatin and 0.25 mg digoxin, all administered orally.
