Brief Summary

The purpose of the study is to assess the relative bioavailability of single doses of 100 mg roxadustat pediatric azo dye-free tablet and 100 mg roxadustat pediatric azo dye-free mini-tablet solid and suspension (new formulations) compared to 100 mg roxadustat azo dye-containing tablet (reference formulation) under fasting conditions in healthy male and female adult participants.

This study will also evaluate the safety and tolerability of single doses of 100 mg roxadustat pediatric azo dye-free tablet and 100 mg roxadustat pediatric azo dye-free mini-tablet solid and suspension (new formulations) and a single dose of 100 mg roxadustat azo dye-containing tablet (reference formulation) under fasting conditions in healthy male and female adult participants.

Detailed Description

This is a 4-period, 4-sequence single dose crossover study. Each participant will participate in 4 treatment periods separated by a washout of at least 7 days between study drug administrations in each period. Participants will be randomized to 1 of 4 sequences.

Participants will be screened for up to 21 days prior to study drug administration on day 1 of period 1. Eligible participants will be admitted to the clinical unit on day -1 of each period and will be residential for 5 days/4 nights.

Participants will receive a single dose of 100 mg roxadustat pediatric azo dye-free tablet, 100 mg roxadustat pediatric azo dye-free mini-tablet (suspension), 100 mg roxadustat pediatric azo dye-free mini-tablet (solid) (new formulations) or 100 mg roxadustat azo dye-containing tablet (reference formulation) under fasting conditions on day 1 of each period.
