Vyndamax Adverse Reactions

Summary of the safety profile: The safety data reflect exposure of 176 patients with ATTR-CM to 80 mg (administered as 4 x 20 mg) of tafamidis meglumine administered daily in a 30-month placebo-controlled trial in patients diagnosed with ATTR-CM (see Pharmacology: Pharmacodynamics under Actions).
The frequency of adverse events in patients treated with 80 mg tafamidis meglumine was generally similar and comparable to placebo.
The following adverse events were reported more often in patients treated with tafamidis meglumine 80 mg compared to placebo: flatulence [8 patients (4.5%) versus 3 patients (1.7%)] and liver function test increased [6 patients (3.4%) versus 2 patients (1.1%)]. A causal relationship has not been established.
Safety data for tafamidis 61 mg are available from its open-label long-term extension study.
Tabulated list of adverse reactions: Adverse reactions are listed as follows by MedDRA System Organ Class (SOC) and frequency categories using the standard convention: Very common (≥1/10), Common (≥1/100 to <1/10), and Uncommon (≥1/1,000 to <1/100). Within the frequency group, adverse reactions are presented in order of decreasing seriousness. Adverse reactions listed in the table as follows are from cumulative clinical data in ATTR-CM participants. (See Table 5.)
