Vyndaqel 61mg is indicated for the treatment of wild‑type or hereditary transthyretin amyloidosis in adult patients with cardiomyopathy
(ATTR-CM).1

▼ This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions. Refer to section 4.8 of the SmPC for how to report adverse reactions.

TTR protein plays an important role in the body—it is vital to some biologic functions including the transport of thyroxine and retinol1-5
  • Thyroid hormones play a vital role in regulating the body's metabolism, heart and digestive functions, muscle control, brain development, and maintenance of bones6 
  • Retinol (also known as Vitamin A) is important for vision, reproduction, growth, and development7  
  • In large cohort studies, low plasma TTR concentrations have been associated with a higher risk of heart failure8*  
  • The long-term impact of TTR reduction in humans is unknown9 

TTR is a tetrameric protein mainly produced in the liver1

An ex-US study of 16,967 participants with consecutively ascertained plasma transthyretin concentration in 2 similar prospective studies of the general population. The Cox regression method was used to examine the association between genetically lower transthyretin concentration and incident heart failure.8 TTR=transthyretin.
