This is a single-arm, open-label, multicenter study designed to evaluate the efficacy, safety, tolerability as well as pharmacodynamics of tafamidis meglumine in ATTR-PN participants in China.
All enrolled participants will receive oral tafamidis meglumine 20 mg soft capsules once daily starting on Day 1. Clinical visits will be scheduled at Baseline (Day 1) and at Week 4, Week 8, Week 12, Week 24, Week 36, Week 48, Week 60 and Week 72. At Week 36 and Week 60 site visit, assessment of adverse events, safety related lab testings, concomitant medications and investigational product compliance will be scheduled. Every 6 weeks (do not exceed 7 weeks since last confirmation) telephone contacts will be made during visits in which no investigative site visits are scheduled for assessment of adverse events, concomitant medications and investigational product compliance (between Week 12 and 24, between Week 24 and 36, between Week 36 and 48, between Week 48 and 60, and between Week 60 and 72).

These 8 domains are also summarized as physical and mental component scores. The score for each domain and component score is the mean of the individual question scores, which are scaled from 0 (minimum) to 100 (maximum), where high scores in each dimension and high overall scores indicate a better quality of life. | Baseline, Weeks 24, 48, and 72 |

Each dimension has 5 levels: 1= no problems, 2= slight problems, 3= moderate problems, 4= severe problems, and 5= extreme problems. Responses to 5 dimensions comprise a health state/a single utility index value. E.g. if a participant responds "no problems" for each 5 dimensions, then health state was coded as "11111" with a predefined index value to it. Every health state (coded as combination of responses on each of 5 dimensions) has a unique predefined utility index value assigned to it, by EuroQol.

| Secondary | Number of Participants With Clinical Laboratory Abnormalities | Protocol-required safety laboratory assessments include: Lymphocytes <0.8 × LLN; Neutrophils <0.8 × LLN, or >1.2 × ULN; Basophils >1.2 × ULN; Activated Partial Thromboplastin Time >1.1 × ULN; Prothrombin Time >1.1 × ULN; Prothrombin International Normalized Ratio >1.1 × ULN; Bilirubin >1.5 × ULN; Urate > 1.2 × ULN; Cholesterol >1.3 × ULN; Potassium <0.9 × LLN; Phosphate >1.2 × ULN; Bicarbonate >1.1 × ULN; Thyroid Stimulating Hormone >1.2 × ULN; URINE Protein ≥1; URINE Hemoglobin ≥1; Nitrite ≥1; URINE Erythrocytes ≥20; Epithelial Cells ≥6; and Casts >1. | All participants who took at least 1 dose of tafamidis meglumine soft gelatin capsule 20 mg | Posted | Count of Participants | Participants | Baseline up to Week 72 |
|
|
|
| Secondary | Transthyretin (TTR) Concentrations on Day 1 (Baseline), and at Weeks 8, 12, 24, 48, and 72 | The TTR (also referred to as pre-albumin) concentrations were determined as pharmacodynamic (PD) biomarkers. | All participants who took at least 1 dose of tafamidis meglumine soft gelatin capsule 20 mg and who had at least 1 TTR concentration value. | Posted | Median | Full Range | Milligrams per deciliter (mg/dL) | Baseline, Weeks 8, 12, 24, 48, and 72 |
|
|
|
| Secondary | TTR Stabilization and Percentage and 95% CI of Responders in TTR Stabilization at Post Baseline Visit | The Fraction of Initial (FOI) is the ratio of the measured TTR tetramer concentration (post-denaturation) to the measured TTR concentration (pre-denaturation). Percent Stabilization (%) is the difference between the dosed FOI and the baseline FOI expressed as a percentage of the baseline FOI. Responder was the participant who achieved TTR stabilization (ie, who had been TTR stabilized). Percentage of responders was number of responders / number of evaluable (i.e., analyzed) participants. | All participants who took at least 1 dose of tafamidis meglumine soft gelatin capsule 20 mg and who had at least 1 TTR stabilization value. | Posted | Number | 95% Confidence Interval | Percentage of participants | Weeks 8, 12, 24, 48, and 72 |
