2.1Recommended Dosage The

recommended dosage is either VYNDAQEL 80 mg (four 20-mg tafamidis meglumine capsules) orally once daily or VYNDAMAX 61 mg (one 61-mg tafamidis capsule) orally once daily. VYNDAMAX and VYNDAQEL are not substitutable on a per mg basis .

2.2Administration Instructions The

capsules should be swallowed whole and not crushed or cut. If a dose is missed, instruct patients to take the dose as soon as remembered or to skip the missed dose and take the next dose at the regularly scheduled time. Do not double the dose.

4. CONTRAINDICATIONS None. None.

8.1Pregnancy 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 ) . 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).

6.1Clinical Trials Experience Because

clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data reflect exposure of 377 ATTR-CM patients to 20 mg or 80 mg (administered as four 20-mg capsules) of VYNDAQEL administered daily for an average of 24.5 months (ranging from 1 day to 111 months). Adverse events were assessed from ATTR-CM clinical trials with VYNDAQEL, primarily a 30-month placebo-controlled trial . The frequency of adverse events in patients treated with VYNDAQEL 20 mg (n=88) or 80 mg (n=176; administered as four 20-mg capsules) was similar to that with placebo (n=177).

In the 30-month placebo-controlled trial, similar proportions of VYNDAQEL-treated patients and placebo-treated patients discontinued the study drug because of an adverse event: 12 (7%), 5 (6%), and 11 (6%) from the VYNDAQEL 80-mg, VYNDAQEL 20-mg, and placebo groups, respectively.
