What is Vyndaqel (tafamidis)?

Vyndaqel (tafamidis) is a medicine indicated for the treatment of transthyretin amyloidosis in patients with stage 1 symptomatic polyneuropathy to delay peripheral neurologic impairment[1]. Vyndaqel (tafamidis) is the first medication approved to stabilise the protein transthyretin (TTR) from misfolding and forming amyloids[3].

It is available in capsule form each containing 20mg of tafamidis.

Who is Vyndaqel (tafamidis) for?

Vyndaqel (tafamidis) is indicated for adults with stage 1 transthyretin familial amyloid polyneuropathy (TTR-FAP).

Polyneuropathies, or peripheral neuropathies, result from damage to the peripheral nerves (nerves that go from the spinal cord to the arms, hands, legs, and feet[2]), which often result in a sense of weakness, numbness and pain in the extremities[1,4].

How does Vyndaqel (tafamidis) work?

Transthyretin amyloidosis is a rare disease characterised by the presence of a defective blood protein called transthyretin (TTR). This defective protein breaks easily, which results in the deposition of a fibrous substance (amyloid fibrils) within the body[5]. The accumulation of amyloid fibrils causes damage to body structures, like tissues and organs, and prevents their normal function[5]. When the nerves are affected the disease is called transthyretin familial amyloid polyneuropathy (TTR-FAP)[10].

The active substance in Vyndaqel, tafamidis, is a transthyretin stabiliser. It attaches to transthyretin, the defective protein, and makes it stable. In this way, it prevents the protein from breaking up, and it may thus stop the formation of amyloid fibrils and slow down the progression of the neurological disorder[5].

Where has Vyndaqel (tafamidis) been approved?

Vyndaqel (tafamidis) has been approved for the treatment of transthyretin familial amyloid polyneuropathy (TTR-FAP) by the:
