Brief Summary
The purpose of this study is the following:
- To evaluate the safety, tolerability, and pharmacokinetics (PK) of orally administered tafamidis in Japanese and Western healthy volunteers at single dose.
- To compare Japanese and Western PK profiles.
- Determine the PD stabilization effect of tafamidis on human transthyretin (TTR) in a validated ex vivo assay.
