About this trial

This is an interventional basic science trial for TTR Cardiomyopathy focused on measuring Pharmacokinetic, pharmacodynamic

Eligibility Criteria

21 Years - 55 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Healthy, males or females, 21 to 55 years old.
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m2.

Exclusion Criteria:

Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).

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 (%)
