Clinical 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.

Adverse reactions reported by at least 3% of EPANOVA-treated individuals and with a higher incidence than placebo (olive oil), based on pooled data from two clinical trials of 6-and 12-week duration involving subjects with hypertriglyceridemia, are listed in Table 1.

Table 1: Adverse Reactions Occurring at Incidence ≥3% and Greater than Placebo in Placebo-Controlled Trials*

Adverse Reaction Placebo
2 g
4 g
Diarrhea 2% 7% 15%
Nausea 1% 4% 6%
Abdominal pain or discomfort 2% 3% 5%
Eructation <1% 3% 3%
* Trials included subjects with hypertriglyceridemia of varying severity.

Additional adverse reactions included vomiting, flatulence and dysgeusia.

In a pool of two longer-term (≥52 weeks) placebo-controlled clinical trials involving 748 patients (376 EPANOVA 4 grams per day; 372 placebo) with chronic gastrointestinal disease, additional common adverse reactions reported more often by EPANOVA-treated patients included abdominal distension, constipation, vomiting, fatigue, nasopharyngitis, arthralgia, and dysgeusia.
