Further study details as provided by Pfizer:

Primary Outcome Measures:

To evaluate the safety and tolerability of orally administered tafamidis in healthy volunteers at escalating doses >120 mg. Safety assessments will include spontaneous reporting of adverse events, concomitant medications, physical examination, [ Time Frame: Day 0 and Day 6 ]
vital signs, ECGs, and clinical laboratory tests. [ Time Frame: Day 0 and Day 6 ]

Secondary Outcome Measures:

Cmax - Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
tmax - Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
AUC0-24 - AreArea under the Concentration-Time Curve (AUC) [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
AUClast - Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)] [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
AUCinf - Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)] [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
t½ - Plasma Decay Half-Life (t1/2) [ Time Frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 120 hrs ]
Transthyretin blood concentration in mg/dL [ Time Frame: Days 0,1,2,3,4,5,6 ]
Transthyretin stabilization (%) [ Time Frame: Days 0,1,2,3,4,5,6 ]
