However, limited available human data with VYNDAQEL use in pregnant women (at a dose of 20 mg per day) have not identified any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproductive studies, oral administration of tafamidis meglumine to pregnant rabbits during organogenesis resulted in adverse effects on development (embryofetal mortality, fetal body weight reduction and fetal malformation) at a dosage providing approximately 9 times the human exposure (AUC) at the maximum recommended human dose (MRHD) of VYNDAQEL (80 mg), and increased incidence of fetal skeletal variation at a dosage providing equivalent human exposure (AUC) at the MRHD. Postnatal mortality, growth retardation, and impaired learning and memory were observed in offspring of pregnant rats administered tafamidis meglumine during gestation and lactation at a dosage approximately 2 times the MRHD based on body surface area (mg/m 2 ) (see Data ) . Advise pregnant women of the potential risk to a fetus. Report pregnancies to the Pfizer reporting line at 1-800-438-1985. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In pregnant rats, oral administration of tafamidis meglumine (0, 15, 30, and 45 mg/kg/day) throughout organogenesis resulted in decreased fetal body weights at ≥30 mg/kg/day (approximately 10 times the human exposure at the MRHD based on AUC). The no-observed-adverse-effect-level (NOAEL) for embryofetal development in rats was 15 mg/kg/day (approximately 7 times the human exposure at the MRHD based on AUC). In pregnant rabbits, oral administration of tafamidis meglumine (0, 0.5, 2, and 8 mg/kg/day) throughout organogenesis resulted in increased embryofetal mortality, reduced fetal body weights, and an increased incidence of fetal malformations at 8 mg/kg/day (approximately 9 times the human exposure at the MRHD based on AUC), which was also maternally toxic. Increased incidences of fetal skeletal variations were observed at doses ≥0.5 mg/kg/day (approximately equivalent to the human exposure at the MRHD based on AUC). In the pre- and postnatal study, pregnant rats received oral administration of tafamidis meglumine at doses of 0, 5, 15, or 30 mg/kg/day throughout pregnancy and lactation (Gestation Day 7 to Lactation Day 20). Decreased survival and body weights, delayed male sexual maturation and neurobehavioral effects (learning and memory impairment) were observed in the offspring of dams treated at 15 mg/kg/day (approximately 2 times the MRHD on a mg/m 2 basis). The NOAEL for pre- and postnatal development in rats was 5 mg/kg/day (approximately equivalent to the MRHD on a mg/m 2 basis)."],"overdosage":["10.

Patients were randomized in a 1:2:2 ratio to receive VYNDAQEL 20 mg (n=88), VYNDAQEL 80 mg (administered as four 20-mg VYNDAQEL capsules) (n=176), or matching placebo (n=177) once daily for 30 months, in addition to standard of care (e.g., diuretics). Treatment assignment was stratified by the presence or absence of a variant TTR genotype as well as baseline disease severity (NYHA Class). Transplant patients were excluded from this study.

The method compared each patient to every other patient within each stratum in a pair-wise manner that proceeded in a hierarchical fashion using all-cause mortality followed by frequency of cardiovascular-related hospitalizations when patients could not be differentiated based on mortality. This analysis demonstrated a significant reduction (p=0.0006) in all-cause mortality and frequency of cardiovascular-related hospitalizations in the pooled VYNDAQEL 20-mg and 80-mg groups versus placebo (Table 2).

The hazard ratio from the all-cause mortality Cox-proportional hazard model for pooled VYNDAQEL versus placebo was 0.70 (95% confidence interval [CI] 0.51, 0.96), indicating a 30% relative reduction in the risk of death relative to the placebo group (p=0.026). Approximately 80% of total deaths were cardiovascular-related in both treatment groups. A Kaplan-Meier plot of time to event all-cause mortality is presented in Figure 1.

A significant treatment effect favoring VYNDAQEL was first observed at Month 6 and remained consistent through Month 30 on both 6MWT distance and KCCQ-OS score (Figure 2 and Table 4). Figure 2: Change from Baseline to Month 30 in 6MWT Distance and KCCQ-OS Score Abbreviations: 6MWT=6-Minute Walk Test, KCCQ-OS=Kansas City Cardiomyopathy Questionnaire-Overall Summary. Panel A shows change from Baseline to Month 30 in pooled VYNDAQEL patients compared with placebo patients in 6MWT distance. Panel B shows change from Baseline to Month 30 in pooled VYNDAQEL patients compared with placebo patients in KCCQ-OS score. The Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS) score is composed of four domains including Total Symptoms (Symptom Frequency and Symptom Burden), Physical Limitation, Quality of Life, and Social Limitation. The Overall Summary score and domain scores range from 0 to 100, with higher scores representing better health status. All four domains favored pooled VYNDAQEL compared to placebo at Month 30, and demonstrated similar treatment effects to the KCCQ-OS score (Figure 2 and Table 4). The distribution for change from Baseline to Month 30 for KCCQ-OS (Figure 3) shows that the proportion of patients with worse KCCQ-OS scores was lower for the pooled VYNDAQEL-treated group compared to placebo, and the proportion with improved scores was higher (Figure 3).

Figure 1 Figure 2 Figure 3 Figure 4"],"pharmacodynamics":["12.2 Pharmacodynamics A proprietary TTR stabilization assay was utilized as a pharmacodynamic marker and assessed the stability of the TTR tetramer ex vivo. The TTR stabilization assay quantifies immunoturbidimetric measurement of the stable TTR tetramer in plasma pre- and post-treatment with 2-day in vitro denaturation with urea. Using this proprietary assay, a dose-dependent trend for greater TTR tetramer stabilization is observed for VYNDAQEL 80-mg compared to VYNDAQEL 20-mg. However, the clinical relevance of a higher TTR tetramer stabilization towards cardiovascular outcomes is not known. VYNDAQEL stabilized both the wild-type TTR tetramer and the tetramers of 14 TTR variants tested clinically after once-daily dosing. Tafamidis also stabilized the TTR tetramer for 25 variants tested ex vivo. VYNDAQEL and VYNDAMAX may decrease serum concentrations of total thyroxine, without an accompanying change in thyroid stimulating hormone (TSH). This reduction in total thyroxine values is probably the result of reduced thyroxine binding to or displacement from transthyretin (TTR) due to the high binding affinity of tafamidis to the TTR thyroxine receptor. No corresponding clinical findings consistent with hypothyroidism have been observed. Biomarkers associated with heart failure (NT-proBNP and Troponin I) favored VYNDAQEL over placebo. Cardiac Electrophysiology At approximately 2.2 times the steady state peak plasma concentration (C max ) at the recommended dose, tafamidis does not prolong the QTc interval to any clinically relevant extent."],"pharmacokinetics":["12.3 Pharmacokinetics No clinically significant differences in steady state C max and area under the plasma concentration over time curve (AUC) of tafamidis were observed for VYNDAMAX 61-mg capsule compared to VYNDAQEL administered as four 20-mg capsules. Tafamidis exposure increases proportionally over single (up to 480 mg) or multiple (up to 80 mg) (1 to 6 times the approved recommended dosage) once daily dosing. The apparent clearance were similar after single and repeated administration of VYNDAQEL 80 mg. Absorption Median tafamidis peak concentrations occurred within 4 hours following dosing. Effect of Food No clinically significant differences in the pharmacokinetics of tafamidis were observed following administration of a high fat, high calorie meal. Distribution The apparent steady state volume of distribution of tafamidis meglumine is 16 liters and 18.5 liters for tafamidis. Plasma protein binding of tafamidis is >99% in vitro. Tafamidis primarily binds to TTR. Elimination The mean half-life of tafamidis is approximately 49 hours. The apparent oral clearance of tafamidis meglumine is 0.228 L/h (0.263 L/h for tafamidis). The degree of drug accumulation at steady state after repeated tafamidis daily dosing is approximately 2.5-fold greater than that observed after a single dose. Metabolism The metabolism of tafamidis has not been fully characterized. However, glucuronidation has been observed. Excretion After a single oral dose of tafamidis meglumine 20 mg, approximately 59% of the dose was recovered in feces (mostly as the unchanged drug) and approximately 22% of the dose was recovered in urine (mostly as the glucuronide metabolite). Specific Populations No clinically significant differences in the pharmacokinetics of tafamidis were observed based on age, race/ethnicity (Caucasian and Japanese) or renal impairment. Patients with Hepatic Impairment Patients with moderate hepatic impairment (Child-Pugh Score of 7 to 9) had decreased systemic exposure (approximately 40%) and increased clearance (approximately 68%) of tafamidis compared to healthy subjects. As TTR levels are lower in subjects with moderate hepatic impairment than in healthy subjects, the exposure of tafamidis relative to the amount of TTR is sufficient to maintain stabilization of the TTR tetramer in these patients. No clinically significant differences in the pharmacokinetics of tafamidis were observed in patients with mild hepatic impairment (Child Pugh Score of 5 to 6) compared to healthy subjects. The effect of severe hepatic impairment on tafamidis is unknown. Drug Interaction Studies Clinical Studies CYP3A4 substrates: No clinically significant differences in the pharmacokinetics of midazolam (a CYP3A4 substrate) or on the formation of its active metabolite (1-hydroxymidazolam) were observed when a single 7.5-mg dose of midazolam was administered prior to and after a 14-day regimen of VYNDAQEL 20-mg once daily. BCRP substrates: Tafamidis inhibits breast cancer resistant protein (BCRP). In a clinical study in healthy participants, AUC inf and C max of the BCRP substrate rosuvastatin increased by 96.75% and 85.59%, respectively following multiple doses of VYNDAMAX 61 mg daily dosing. In Vitro Studies Cytochrome P450 Enzymes : Tafamidis induces CYP2B6 and CYP3A4 and does not induce CYP1A2. Tafamidis does not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP3A4/5 or CYP2D6. UDP glucuronosyltransferase (UGT) : Tafamidis inhibits intestinal activities of UGT1A1 but neither induces nor inhibits other UDP glucuronosyltransferase (UGT) systemically. Transporter Systems : In vitro studies and model predictions show that tafamidis has a low potential to inhibit organic anion transporters OAT1 and OAT3 at clinically relevant concentrations. Tafamidis did not show a potential to inhibit Multi-Drug Resistant Protein (MDR1) (also known as P-glycoprotein; P-gp), organic cation transporter OCT2, multidrug and toxin extrusion transporters MATE1 and MATE2K and, organic anion transporting polypeptide OATP1B1 and OATP1B3."],"adverse_reactions":["6.

USE IN SPECIFIC POPULATIONS • Pregnancy: Based on animal studies, may cause fetal harm. ( 8.1 ) • Lactation: Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings from animal studies, VYNDAQEL and VYNDAMAX may cause fetal harm when administered to a pregnant woman. However, limited available human data with VYNDAQEL use in pregnant women (at a dose of 20 mg per day) have not identified any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproductive studies, oral administration of tafamidis meglumine to pregnant rabbits during organogenesis resulted in adverse effects on development (embryofetal mortality, fetal body weight reduction and fetal malformation) at a dosage providing approximately 9 times the human exposure (AUC) at the maximum recommended human dose (MRHD) of VYNDAQEL (80 mg), and increased incidence of fetal skeletal variation at a dosage providing equivalent human exposure (AUC) at the MRHD. Postnatal mortality, growth retardation, and impaired learning and memory were observed in offspring of pregnant rats administered tafamidis meglumine during gestation and lactation at a dosage approximately 2 times the MRHD based on body surface area (mg/m 2 ) (see Data ) . Advise pregnant women of the potential risk to a fetus. Report pregnancies to the Pfizer reporting line at 1-800-438-1985. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In pregnant rats, oral administration of tafamidis meglumine (0, 15, 30, and 45 mg/kg/day) throughout organogenesis resulted in decreased fetal body weights at ≥30 mg/kg/day (approximately 10 times the human exposure at the MRHD based on AUC). The no-observed-adverse-effect-level (NOAEL) for embryofetal development in rats was 15 mg/kg/day (approximately 7 times the human exposure at the MRHD based on AUC). In pregnant rabbits, oral administration of tafamidis meglumine (0, 0.5, 2, and 8 mg/kg/day) throughout organogenesis resulted in increased embryofetal mortality, reduced fetal body weights, and an increased incidence of fetal malformations at 8 mg/kg/day (approximately 9 times the human exposure at the MRHD based on AUC), which was also maternally toxic. Increased incidences of fetal skeletal variations were observed at doses ≥0.5 mg/kg/day (approximately equivalent to the human exposure at the MRHD based on AUC). In the pre- and postnatal study, pregnant rats received oral administration of tafamidis meglumine at doses of 0, 5, 15, or 30 mg/kg/day throughout pregnancy and lactation (Gestation Day 7 to Lactation Day 20). Decreased survival and body weights, delayed male sexual maturation and neurobehavioral effects (learning and memory impairment) were observed in the offspring of dams treated at 15 mg/kg/day (approximately 2 times the MRHD on a mg/m 2 basis). The NOAEL for pre- and postnatal development in rats was 5 mg/kg/day (approximately equivalent to the MRHD on a mg/m 2 basis). 8.2 Lactation Risk Summary There are no available data on the presence of tafamidis in human milk, the effect on the breastfed infant, or the effect on milk production. Tafamidis is present in rat milk (see Data ) . When a drug is present in animal milk, it is likely the drug will be present in human milk. Based on findings from animal studies which suggest the potential for serious adverse reactions in the breastfed infant, advise patients that breastfeeding is not recommended during treatment with VYNDAQEL or VYNDAMAX. Data Pregnant and lactating female rats were administered repeated daily oral doses of tafamidis meglumine (15 mg/kg/day) followed by a single oral gavage dose of 14 C-tafamidis meglumine on Lactation Day 4 or 12. Radioactivity was observed in milk by 1 hour post-dose and increased thereafter. The ratio of the highest radioactivity associated with 14 C tafamidis meglumine in milk (8 hours post-dose) vs. plasma (1 hour post-dose) was approximately 1.6 on Day 12, indicating tafamidis meglumine is transferred to milk after oral administration. 8.3 Females and Males of Reproductive Potential Contraception Females Based on findings from animal studies, VYNDAQEL and VYNDAMAX may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Consider pregnancy planning and prevention for females of reproductive potential. 8.4 Pediatric Use The safety and effectiveness of VYNDAQEL and VYNDAMAX have not been established in pediatric patients. 8.5 Geriatric Use No dosage adjustment is required for elderly patients (≥65 years) [see Clinical Pharmacology (12.3) ] .

It was FDA-approved in 2019 for the treatment of amyloid polyneuropathy type I, amyloidosis, transthyretin-related familial amyloid cardiomyopathy, and wild-type transthyretin cardiac amyloidosis. Vyndaqel works by stabilizing the Transthyretin protein, preventing its misfolding and aggregation into amyloid fibrils. The drug has a half-life of 49 hours and is currently patented, with no generic manufacturers available. Key safety considerations include its potential effects on the liver and kidneys.","brandName":"Vyndaqel","ecosystem":[{"indication":"Amyloid polyneuropathy type I","otherDrugs":[],"globalPrevalence":null},{"indication":"Amyloidosis","otherDrugs":[{"name":"acetylcysteine","slug":"acetylcysteine","company":"Apothecon"},{"name":"cysteine","slug":"cysteine","company":"Hospira"}],"globalPrevalence":23200000},{"indication":"Transthyretin related familial amyloid cardiomyopathy","otherDrugs":[],"globalPrevalence":23200000},{"indication":"Wild-type transthyretin cardiac amyloidosis","otherDrugs":[],"globalPrevalence":23200000}],"mechanism":{"target":"Transthyretin","novelty":"Follow-on","targets":[{"gene":"TTR","source":"DrugCentral","target":"Transthyretin","protein":"Transthyretin"},{"gene":"ABCG2","source":"DrugCentral","target":"ATP-binding cassette sub-family G member 2","protein":"ATP-binding cassette sub-family G member 2"},{"gene":"SLC22A8","source":"DrugCentral","target":"Solute carrier family 22 member 8","protein":"Solute carrier family 22 member 8"},{"gene":"SLC22A6","source":"DrugCentral","target":"Solute carrier family 22 member 6","protein":"Solute carrier family 22 member 6"}],"modality":"Small Molecule","drugClass":"tafamidis","explanation":"Tafamidis is selective stabilizer of TTR.

It can be used to treat both hereditary forms, familial amyloid cardiomyopathy and familial amyloid polyneuropathy, as well as wild-type transthyretin amyloidosis, which formerly was called senile systemic amyloidosis. It works by stabilizing the quaternary structure of the protein transthyretin. In people with transthyretin amyloidosis, transthyretin falls apart and forms clumps called (amyloid) that harm tissues including nerves and the heart.","wiki_history":"== History==\nThe laboratory of Jeffery W. Kelly at The Scripps Research Institute began looking for ways to inhibit transthyretin fibril formation in the 1990s. Tafamidis was eventually discovered by Kelly's team using a structure-based drug design strategy; the chemical structure was first published in 2003. and FoldRx developed tafamidis up through submitting an application for marketing approval in Europe in early 2010. FoldRx was acquired by Pfizer later that year. The U.S. Food and Drug Administration rejected the application for marketing approval in 2012, on the basis that the clinical trial did not show efficacy based on a functional endpoint, and requested further clinical trials. In May 2019, the FDA approved two tafamidis preparations, Vyndaqel (tafamidis meglumine) and Vyndamax (tafamidis), for the treatment of transthyretin-mediated cardiomyopathy.\n\nThe FDA approved tafamidis meglumine based primarily on evidence from a clinical trial of 441 adult patients conducted at 60 sites in Belgium, Brazil, Canada, Czech Republic, Spain, France, Greece, Italy, Japan, Netherlands, Sweden, Great Britain, and the United States.","wiki_society_and_culture":"== Society and culture ==\n=== Legal status ===\nTafamidis was approved in the European Union in 2011 for the treatment of transthyretin amyloidosis with polyneuropathy, and in Japan in 2013. The two preparations have the same active moiety, tafamidis, but they are not substitutable on a milligram to milligram basis.\n\nTafamidis (Vyndamax) and tafamidis meglumine (Vyndaqel) were approved

As of 2025, the Vyndaqel market size has reached $1.9 billion, with a projected growth rate of 17.1% CAGR to reach $4.19 billion by 2030 [1]. This growth is driven by the increasing adoption of precision medicine and facility expansions in the market [2].\n\nThe competitive landscape of Vyndaqel is dominated by Pfizer, with no significant competitors in the market [3]. However, the patent for Vyndaqel is set to expire in 2030, which may lead to increased competition from generic versions of the medication [4]. Additionally, the label expansion of Vyndaqel to treat wild-type transthyretin cardiac amyloidosis has increased its market potential [5].\n\nKey upcoming catalysts for the Vyndaqel market include the launch of pipeline competitors, such as Alnylam's patisiran, which is currently in phase 3 clinical trials [6]. Furthermore, the market is expected to grow significantly, with a projected market size of $17.56 billion by 2031 at a CAGR of 13.02% [7]. The fastest-growing region in the market is expected to be Asia-Pacific, with North America being the largest market [8].\n\nIn conclusion, Vyndaqel has established itself as a leading treatment for transthyretin amyloidosis, with a strong market position and revenue trajectory. However, the patent cliff and increased competition from generic versions of the medication may pose a threat to its market share. The market is expected to grow significantly, with key upcoming catalysts including the launch of pipeline competitors and label expansions.\n\nReferences:\n[1] Research and Markets, Vyndaqel Market Report 2026\n[2] The Business Research Company, Vyndaqel Market Size, Share, Growth and Trends Report 2026\n[3] Mordor Intelligence, Vyndaqel Market Size, Trends, Share, 2031 Growth Report\n[4] Research and Markets, Vyndaqel Market Report 2026\n[5] The Business Research Company, Vyndaqel Market Size, Share, Growth and Trends Report 2026\n[6] Mordor Intelligence, Vyndaqel Market Size, Trends, Share, 2031 Growth Report\n[7] Mordor Intelligence, Vyndaqel Market Size, Trends, Share, 2031 Growth Report\n[8] Mordor Intelligence, Vyndaqel Market Size, Trends, Share, 2031 Growth Report","model":"llama-3.1-8b (Groq)","sources":[{"url":"https://www.mordorintelligence.com/industry-reports/vyndaqel-market","date":"","title":"Vyndaqel Market Size, Trends, Share, 2031 Growth Report","source":"www.mordorintelligence.com"},{"url":"https://www.thebusinessresearchcompany.com/report/vyndaqel-global-market-report","date":"","title":"Vyndaqel Market Size, Share, Growth and Trends Report 2026","source":"www.thebusinessresearchcompany.com"},{"url":"https://www.researchandmarkets.com/report/vyndaqel-market?srsltid=AfmBOooYneTQxUdTmnjT0u_lg6yKkX-jGpKDxDwJdOroxFzeHnobOlZn","date":"","title":"Vyndaqel Market Size, Competitors, Trends & Forecast to 2030","source":"www.researchandmarkets.com"}],"disclaimer":"AI-generated analysis based on public sources.
