Outcomes
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,
vital signs, ECGs, and clinical laboratory tests.
Secondary Outcome Measures
Cmax - Maximum Observed Plasma Concentration (Cmax)
tmax - Time to Reach Maximum Observed Plasma Concentration (Tmax)
AUC0-24 - AreArea under the Concentration-Time Curve (AUC)
AUClast - Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)]
AUCinf - Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)]
t½ - Plasma Decay Half-Life (t1/2)
Transthyretin blood concentration in mg/dL
Transthyretin stabilization (%)
