Tafamidis meglumine (Vyndaqel®, Pfizer) is a novel, first-in-class drug for the treatment of transthyretin familial amyloid polyneuropathy (TTR-FAP), a rare neurodegenerative disorder characterized by progressive sensory, motor and autonomic impairment that is ultimately fatal. Pathogenic mutations in the transthyretin (TTR) protein lead to destabilization of its tetrameric structure and subsequent formation of amyloid aggregates. Tafamidis is a small-molecule inhibitor that binds selectively to TTR in human plasma and kinetically stabilizes the tetrameric structure of both wild-type TTR and a number of different mutants. Clinical trials indicate that tafamidis slows disease progression in patients with TTR-FAP and reduces the burden of disease, demonstrating improvement in small and large nerve fiber function, modified body mass index and lower extremity neurological examination. Tafamidis meglumine has been launched for TTR FAP in the EU, Japan, Argentina, Malta and Mexico, and is preregistration in the US for this indication.

Sample Use Guides

In Vivo Use Guide

The recommended dose of tafamidis meglumine is 20 mg orally once daily.

Route of Administration: Oral

In Vitro Use Guide

Tafamidis effectively inhibited fibril formation induced by acid denaturation in a concentration-dependent manner with similar potency for wild-type TTR, V30M TTR and V122I TTR, reaching its EC50 at a tafamidis:TTR stoichiometry of <1 (EC50 was in the range of 2.7-3.2 uM, corresponding to a tafamidis: TTR stoichiometry range of 0.75-0.9).
