PK Cohort 1PalovaroteneSubjects received three single oral doses of palovarotene on Days 1, 6, and 11, separated by 5-day washout periods. Sequence A-B-C: Subjects received a single oral dose of palovarotene whole capsule under fasting conditions (at least a 10-hour overnight fast); followed by a single oral dose of palovarotene whole capsule 30 minutes after the start of a standardized high-fat, high-caloric breakfast; and then followed by a single oral dose of palovarotene sprinkled on 1 teaspoon of apple sauce, administered 30 minutes after the start of a standardized high-fat, high-caloric breakfast.
PK Cohort 2PalovaroteneSubjects received three single oral doses of palovarotene on Days 1, 6, and 11, separated by 5-day washout periods. Sequence B-C-A: Subjects received a single oral dose of palovarotene whole capsule 30 minutes after the start of a standardized high-fat, high-caloric breakfast; followed by a single oral dose of palovarotene sprinkled on 1 teaspoon of apple sauce, administered 30 minutes after the start of a standardized high-fat, high-caloric breakfast; and then followed by a single oral dose of palovarotene whole capsule under fasting conditions (at least a 10-hour overnight fast).
PK Cohort 3PalovaroteneSubjects received three single oral doses of palovarotene on Days 1, 6, and 11, separated by 5-day washout periods. Sequence C-A-B: Subjects received a single oral dose of palovarotene sprinkled on 1 teaspoon of apple sauce, administered 30 minutes after the start of a standardized high-fat, high-caloric breakfast; followed by a single oral dose of palovarotene whole capsule under fasting conditions (at least a 10-hour overnight fast); and then followed by a single oral dose of palovarotene whole capsule 30 minutes after the start of a standardized high-fat, high-caloric breakfast.
Drug-Drug interaction (DDI) CohortPalovaroteneOn the morning of Day 1, subjects received a single dose of midazolam 30 minutes after the start of a standardized breakfast. On Day 2 (after the 24-hour midazolam blood draw) through Day 15, subjects received a daily, single dose of palovarotene in the morning 30 minutes after the start of a standardized breakfast. A second dose of midazolam was administered on Day 15 in the morning (immediately following the palovarotene dose) 30 minutes after the start of a standardized breakfast.
Drug-Drug interaction (DDI) CohortmidazolamOn the morning of Day 1, subjects received a single dose of midazolam 30 minutes after the start of a standardized breakfast. On Day 2 (after the 24-hour midazolam blood draw) through Day 15, subjects received a daily, single dose of palovarotene in the morning 30 minutes after the start of a standardized breakfast. A second dose of midazolam was administered on Day 15 in the morning (immediately following the palovarotene dose) 30 minutes after the start of a standardized breakfast.
