A Study Comparing the Amounts of 2 Different Forms of Tafamidis (PF06291826), Both With and Without Food, In the Blood

2 different formulations of tafamidis will be compared under both fed and fasted conditions. Subjects will be fasted overnight or fed. After swallowing one of the tafamidis formulations, tafamidis blood concentrations will be measured periodically for 8 days. After 16 days, subjects will take a different formulation in the fed or fasted state or take the same formulation in the opposite feeding condition. This will be repeated, 16 days apart, until all subjects have taken each formulation both fed and fasted.
