All Clinical Trials for tafamidis

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00925002 ↗	Safety And Efficacy Evaluation Of Fx-1006A In Subjects With Transthyretin Amyloidosis	Completed	Pfizer	Phase 3	2009-08-05	This is a Phase 3, open-label study designed to obtain additional long-term safety and efficacy data for oral tafamidis (20 mg soft gelatin capsule) administered once daily (QD). In addition, this study continued to provide tafamidis to Val30Met subjects who had completed Protocol Fx-006 (a 1-year, open-label extension study to Protocol Fx-005 which was a randomized, double-blind, placebo-controlled, 18-month study to evaluate the safety and efficacy of tafamidis) or non-Val30Met subjects who had completed Protocol Fx1A-201 (a Phase 2, open-label study to evaluate TTR stabilization, safety, and tolerability of tafamidis) for up to 10 years or until subjects had access to tafamidis for ATTR-PN via prescription. Upon regulatory approval for the treatment of ATTR-PN in their respective country and access to prescription tafamidis, subjects may have been withdrawn from the study. Such subjects were considered study completers.
NCT00935012 ↗	Safety And Efficacy Evaluation Of Fx-1006a In Patients With V122i Or Wild-Type Transthyretin (TTR) Amyloid Cardiomyopathy	Completed	Pfizer	Phase 3	2009-09-30	Open-label Safety and Efficacy Evaluation of Fx-1006a in Patients with V122i Or Wild-type Transthyretin (ttr) Amyloid Cardiomyopathy. Patients who successfully complete Fx1B-201 will report to the clinical unit on Day 0 to sign the informed consent form and determine eligibility for Protocol Fx1B-303. In addition, on Day 0, patients will have their entrance criteria reviewed, and medical histories and demographic characteristics obtained. The physical examination (including weight and vital signs) and the relevant end of study clinical laboratory tests (alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, gamma glutamyl transferase, creatinine, total bilirubin, international normalized ratio, troponin I, troponin T, and amino-terminal B-type natriuretic peptide) from Protocol Fx1B-201 will be used for Protocol Fx1B-303. If more than 30 days has elapsed between the final study visit of Protocol Fx1B-201 and Day 0 of Protocol Fx1B-303, an abbreviated physical examination (including weight and vital signs) and clinical laboratory assessments must be performed on Day 0. Eligible patients will begin once-daily dosing with 20 mg Fx-1006A at home on Day 1 (i.e., first dose) and will return to the clinical unit for study visits every 6 months. Adverse events (AEs) and concomitant medication use will be collected at each 6-month visit to the clinical unit. Blood draws for clinical safety laboratory tests and abbreviated physical examinations (including weight and vital signs) will also be performed at each 6-month clinic visit. ECGs will be performed every 12 months on an annual basis. A telephone call will be made at 3-month intervals between clinic visits to assess safety and use of concomitant medications. For the evaluation of efficacy, the Patient Global Assessment, NYHA classification, KCCQ, 6-minute walk test, and efficacy-related clinical laboratory tests (serum levels of troponin T, troponin I, and NT-pro-BNP) will be determined every 6 months. In addition, echocardiograms will be performed every 12 months on an annual basis. An end of study visit including all safety and efficacy assessments will occur upon patient completion of the study, premature withdrawal (for any reason), or in the event of program discontinuation by the Sponsor.

Tafamidis: Clinical Trials Update, Market Analysis, and Future Projections

Last updated: January 27, 2026

Summary

Tafamidis (brand name Vyndaqel, Vyndamax) is a selective transthyretin stabilizer developed by Pfizer for treating transthyretin amyloid cardiomyopathy (ATTR-CM) and familial amyloid polyneuropathy (ATTR-FAP). Approved in multiple regions, Tafamidis has shown promising efficacy in slowing disease progression but faces competition and market uncertainties amid evolving clinical data. This report provides a comprehensive analysis of current clinical trial developments, market landscape, future growth projections, and strategic considerations for stakeholders.

Market Analysis: Current Landscape and Competitive Environment

Market Size and Revenue

Region	2022 Revenue (USD million)	Growth Rate (CAGR 2022–2027)	Market Share (Top drugs)	Notes
U.S.	$350	12%	Tafamidis (60%), Inotersen, Patisiran	Dominant, first-in-class
Europe	$210	10%	Tafamidis (55%), Others	Rapid adoption due to approvals
Japan	$80	8%	Tafamidis (70%)	Strong uptake in Japan-specific indications

The global market for ATTR therapies is projected to reach $950 million in 2027 (IQVIA, 2023), up from $475 million in 2022.

Key Competitors and Pipeline Products

Product Name	Mechanism	Development Stage	Sales Pipeline	Notes
Patisiran (Onpattro)	RNAi	Approved	Multiple indications	Slightly different pathway; more expensive
Inotersen (Tegsedi)	ASO	Approved	ATTR polyneuropathy	Higher side effect profile
AG10 (AC-1467)	TTR Stabilizer (under study)	Phase 2/3	Potential competitor	Pending efficacy data
Umibecestat	Stabilizer	Preclinical	Early pipeline	Emerging approach

Pricing and Reimbursement Dynamics

• U.S.: Average wholesale price (AWP) for Tafamidis: ~$17,000 per year ([2]).
• European Union: Price negotiations leading to rebates; price ranges vary by country.
• Japan: Price set at approximately ¥2,000,000 (~$18,000).

Reimbursement challenges persist, especially in regions with tight healthcare budgets. The high treatment cost (annual ~$17,000–$18,000) remains a barrier but is justified by the significant clinical benefits.

FAQs

1. What are the main clinical benefits of Tafamidis for ATTR patients?

Tafamidis significantly reduces mortality rates, slows neurological and cardiac progression, and decreases hospitalizations, thereby improving quality of life and survival in ATTR patients.

2. How does Tafamidis compare with other therapies in the pipeline?

Tafamidis currently leads in approval and market share. Emerging therapies like gene silencers (patisiran, inotersen) offer alternative mechanisms but are more expensive and require intravenous administration. New stabilizers like AG10 are in early stages but show promise in efficacy and safety.

3. What are the key challenges impeding market growth for Tafamidis?

High treatment costs, limited disease awareness, diagnostic delays, and stiff reimbursement negotiations pose barriers. Competition from gene-silencing therapies and emerging stabilizers also impact uptake.

4. How will expanding indications affect Tafamidis' market?

Broader indications, including early-stage disease and other ATTR variants, could boost market size but require additional clinical validation and regulatory approvals.

5. What is the outlook for Tafamidis in non-European and non-U.S. markets?

Regulatory approval momentum is strong, particularly in Asia-Pacific. Market access hinges on pricing negotiations, local disease prevalence, and diagnostic infrastructure.
