Pfizer Receives Positive CHMP Opinion for VYNDAQEL® (tafamidis) for Use in Patients with Transthyretin Amyloid Cardiomyopathy, a Rare and Fatal Disease

-If approved by the European Commission (EC), tafamidis will be the first pharmacologic therapy in the EU for patients with transthyretin amyloid cardiomyopathy-

Pfizer Ltd, Walton Oaks, UK – 13 December 2019: Pfizer Ltd announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the approval of VYNDAQEL® (tafamidis), a once-daily 61 mg oral capsule, for the treatment of wild-type or hereditary transthyretin amyloidosis in adult patients with cardiomyopathy (ATTR-CM).1  

“The CHMP positive opinion for tafamidis marks an important step forward in helping people living with ATTR-CM, a rare and fatal heart disease, who to date have had no effective treatment options available to them,” said Owen Marks, Head of Rare Diseases at Pfizer UK, “Pfizer is committed to investing in and supporting people living with this rare and fatal form of heart disease.” 

ATTR-CM is a rare, life-threatening disease characterised by the buildup of abnormal deposits of misfolded protein called amyloid in the heart and is defined by restrictive cardiomyopathy and progressive heart failure.2,3,4 On average, patients live only 2 to 3.5 years following diagnosis.5  

The European line extension application was based on the Phase 3 ATTR-ACT study, the first and only completed global, double-blind, randomised, placebo-controlled clinical trial to investigate a pharmacologic therapy for the treatment of ATTR-CM.6 In the primary analysis of the study, tafamidis meglumine demonstrated a significant reduction in the hierarchical combination of all-cause mortality and frequency of cardiovascular-related hospitalisations compared to placebo over a 30-month period in patients with wild-type or hereditary ATTR-CM (p=0.0006).6 Additionally, individual components of the primary analysis demonstrated a relative reduction in the risk of all-cause mortality and frequency of cardiovascular-related hospitalisation of 30% (p=0.026) and 32% (p<0.0001), respectively, with tafamidis versus placebo, with a relative risk ratio of 0.68 (0.48 per year vs. 0.70 per year;95% CI, 0.56 to 0.81).  6 The application is also based on findings from an evaluation of the free acid form of tafamidis 61 mg.7 The ATTR-ACT primary results were presented in a Hot Line session at the ESC Congress 2018 in Munich, Germany, and simultaneously published online in the New England Journal of Medicine (NEJM) in August 2018.  

The CHMP’s opinion will now be reviewed by the European Commission and a final decision is expected in the coming months. 

About ATTR Amyloidosis 

ATTR amyloidosis is rare, progressive disease characterised by the abnormal buildup of amyloid deposits composed of misfolded transthyretin protein in the body’s organs and tissues. ATTR amyloidosis can impact numerous organs and tissues in the body, including the peripheral nervous system, and organs such as the heart, kidneys, gastrointestinal tract, and eyes. ATTR-CM and transthyretin amyloid polyneuropathy (ATTR-PN) are two presentations of the disease.  

ATTR-CM affects the heart and leads to restrictive cardiomyopathy and progressive heart failure. There are two sub-types of ATTR-CM: hereditary, which is caused by a mutation in the transthyretin gene and can occur in people as early as their 50s and 60s; or the wild-type form which is associated with aging, and is thought to be more common, usually affecting men after age 60.8,9 Often ATTR-CM is diagnosed only after symptoms have become severe. Once diagnosed, the median life expectancy in patients with ATTR-CM, dependent on sub-type, is approximately two to 3.5 years.5 

ATTR-PN results from a genetic mutation of the transthyretin gene, amyloid fibrils form in the peripheral and autonomic nerves. ATTR-PN typically occurs during active adult years with onset as early as the 30s in some patients, followed by disease progression that may reach the terminal stage in approximately 10 years on average from disease onset. 

About VYNDAQEL (tafamidis 61 mg) and VYNDAQEL (tafamidis meglumine 20 mg)2,7

Tafamidis 61 mg and tafamidis meglumine 20 mg are oral transthyretin stabilisers that selectively bind to transthyretin, stabilising the tetramer of the transthyretin transport protein and slowing the formation of amyloid that causes ATTR-CM. 

The tafamidis 61 mg capsule corresponds to an 80 mg tafamidis meglumine dose (4x 20 mg capsules) and was developed for patient convenience to enable a single capsule for daily administration. Tafamidis 61 mg and tafamidis 20 mg are not substitutable on a per milligram basis. 

Tafamidis was granted Orphan Drug Designation for ATTR-CM in both the EU and US in 2012 and in Japan in 2018. Tafamidis was approved in Japan under SAKIGAKE designation for the treatment of ATTR-CM in March 2019, in the United States in May 2019, and in the United Arab Emirates in November 2019.   

VYNDAQEL (20 mg) was first approved in 2011 in the EU for the treatment of ATTR-PN, in adult patients with stage 1 symptomatic polyneuropathy to delay peripheral neurologic impairment. Currently, it is approved for ATTR-PN in 40 countries, including Japan, countries in Europe, Brazil, Mexico, Argentina, Israel, Russia, and South Korea. 

Tafamidis has not received marketing authorisation for patients with ATTR-CM in the EU.
