A Study to Assess the Safety and Efficacy of Oral Armour Thyroid Compared to Synthetic T4 for the Treatment of Primary Hypothyroidism in Adult Participants
Sponsor: AbbVie
Summary
This study will evaluate the efficacy and safety of Armour Thyroid treatment compared with synthetic T4 in subjects who have primary hypothyroidism and are currently stabilized (i.e., in-range thyroid-stimulating hormone \[TSH\]) on synthetic T4 treatment. This study will also therefore evaluate the efficacy and safety of dose conversion from synthetic T4 therapy to Armour Thyroid therapy.
Official title: A Phase 2/3 Multicenter, Double Blinded, Randomized, Dose-conversion, Active Control Study Examining the Efficacy and Safety of Armour Thyroid Compared to Synthetic T4 for the Treatment of Adults With Primary Hypothyroidism
