简要总结
The main purpose of this study is to assess the effect of itraconazole on the pharmacokinetic (PK) of baxdrostat.
详细描述
This study will be an open-label, 3-period fixed sequence study conducted at a single Clinical Unit.
The study will comprise of:
- A Screening Period of maximum 28 days
- Period 1: Period 1 will start from Day -1 to Day 6 (followed by pharmacokinetic (PK) sampling of baxdrostat). Baxdrostat administration on Day 1 to Day 6
- Period 2: Period 2 will start from Day 6 (after the last PK sample in period 1) to Day 8. Itraconazole administration on Days 6 to 8 (twice a day [BID] on Day 6 and once daily [QD] on Days 7 and 8)
- Period 3: Period 3 will start from Day 9 to Day 17. Baxdrostat administration on Day 9 and itraconazole administration on Days 9 to 16 QD
- A Final Follow-up Visit at 7 to 14 days after the last baxdrostat PK sample in Period 3
All participants will receive 2 single doses of baxdrostat and 12 doses of itraconazole, under fed conditions.
