Each subject will be given a single oral dose of rosuvastatin on Day 1 in Period 1. In Period 2, after a washout period of at least 5 days, each subject will receive oral doses of tafamidis twice daily (BID) on days 1 and 2, followed by tafamidis once daily (QD) on days 3 to 9 with an oral dose of rosuvastatin on Day 7. Rosuvastatin exposures will be compared between Periods 1 and 2 to estimate the effect of tafamidis on rosuvastatin PK in healthy subjects.
