4 Contraindications

Additions and/or revisions underlined:

OMTRYG is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to omega-3-acid ethyl esters or any of the ingredients in OMTRYG.


5 Warnings and Precautions

Subsection title revised:

5.2 Potential for Allergic Reactions in Patients with Fish Allergy

OMTRYG contains ethyl esters of omega-3 fatty acids (EPA and DHA) obtained from the oil of several fish sources. It is not known whether patients with allergies to fish and/or shellfish are at increased risk of an allergic reaction to OMTRYG. OMTRYG should be used with caution in patients with known hypersensitivity to fish and/or shellfish.

5.3 Recurrent Atrial Fibrillation (AF) or Flutter

Additions and/or revisions underlined:

In a double-blind, placebo-controlled trial of 663 patients with symptomatic paroxysmal AF (n=542) or persistent AF (n=121), recurrent AF or flutter was observed in patients randomized to another omega-3-acid ethyl esters product who received 8 grams/day for 7 days and 4 grams/day thereafter for 23 weeks at a higher rate relative to placebo. Patients in this trial had median baseline TG levels of 127 mg/dL, had no substantial structural heart disease, were taking no anti-arrhythmic therapy (rate control permitted), and were in normal sinus rhythm at baseline.

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

The following important adverse reactions are described below and elsewhere in the labeling:

  • Potential for Allergic Reactions in Patients with Fish Allergy [see Warnings and Precautions (5.1)]
  • Recurrent AF or Atrial Flutter [see Warnings and Precautions (5.2)]

. . .

The safety of OMTRYG has been established in adequate and well-controlled trials of another omega-3 acid ethyl esters product.

8 Use in Specific Populations

8.1 Pregnancy

Risk Summary:

The available data from published case reports and the pharmacovigilance database on the use of omega-3-acid ethyl esters in pregnant women are insufficient to identify a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal studies, omega-3-acid ethyl esters given orally to female rats prior to mating through lactation did not have adverse effects on reproduction or development when given at doses 5 times the maximum recommended human dose (MRHD) of approximately 4 grams/day, based on a body surface area comparison. Omega-3-acid ethyl esters given orally to rats and rabbits during organogenesis was not teratogenic at clinically relevant exposures, based on body surface area comparison (see Data).

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 female rats given oral doses of omega-3-acid ethyl esters (100, 600, or 2,000 mg/kg/day) beginning 2 weeks prior to mating through lactation, no adverse effects were observed at 2,000 mg/kg/day (approximately 5 times the MRHD based on body surface area [mg/m2]).

In a dose-ranging study, female rats given oral doses of omega-3-acid ethyl esters (1,000, 3,000, or 6,000 mg/kg/day) beginning 2 weeks prior to mating through Postpartum Day 7 had decreased live births (20% reduction) and pup survival to Postnatal Day 4 (40% reduction) at or greater than 3,000 mg/kg/day in the absence of maternal toxicity at 3,000 mg/kg/day (approximately 7 times the MRHD based on body surface area [mg/m2]).

In pregnant rats given oral doses of omega-3-acid ethyl esters (1,000, 3,000, and 6,000 mg/kg/day) during organogenesis, no adverse effects were observed in fetuses at a maternally toxic dose (increased food consumption) of 6,000 mg/kg/day (approximately 14 times the MRHD based on body surface area [mg/m2]). In pregnant rats given oral doses of omega-3-acid ethyl esters (100, 600, or 2,000 mg/kg/day) from gestation day 14 through lactation day 21, no adverse effects were seen at 2,000 mg/kg/day (approximately 5 times the MRHD based on body surface area [mg/m2]).

In pregnant rabbits given oral doses of omega-3-acid ethyl esters (375, 750, or 1,500 mg/kg/day) during organogenesis, no adverse effects were observed in fetuses given 375 mg/kg/day (approximately 2 times the MRHD based on body surface area [mg/m2]). However, at higher doses, increases in fetal skeletal variations and reduced fetal growth were evident at maternally toxic doses (reduced food consumption and body weight gain) greater than or equal to 750 mg/kg/day (approximately 4 times the MRHD) and embryolethality was evident at 1500 mg/kg/day (approximately 7 times the MRHD).

8.2 Lactation

PLLR conversion:

Risk Summary

Published studies have detected omega-3 fatty acids, including EPA and DHA, in human milk. Lactating women receiving oral omega-3 fatty acids for supplementation have resulted in higher levels of omega-3 fatty acids in human milk. There are no data available on the effects of OMTRYG on the breastfed infant or on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for OMTRYG and any potential adverse effects on the breastfed child from OMTRYG or from the underlying maternal condition.
