  • 4. Patient meets one of the following criteria: a. Tafamidis-naïve and not actively planning to commence treatment with tafamidis during the first 12 months following randomization (per exclusion criterion #7); or b.

  • 20. Has untreated hypo- or hyperthyroidism
  • 21. Has an active infection requiring systemic antiviral, antiparasitic or antimicrobial therapy that will not be completed prior to dosing (Day 1)
