Twelve (6%) Omegaven-treated patients were listed for liver transplantation (1 patient was listed 18 days before treatment, and 11 patients after a median of 42 days [range: 2 days to 8 months] of treatment); 9 (5%) received a transplant after a median of 121 days (range: 25 days to 6 months) of treatment, and 3 (2%) were taken off the waiting list because cholestasis resolved.
One hundred thirteen (60%) Omegaven-treated patients reached DBil levels less than 2 mg/dL and AST or ALT levels less than 3 times the upper limit of normal, with median AST and ALT levels for Omegaven-treated patients at 89 and 65 U/L, respectively, by the end of the study.
Median hemoglobin levels and platelet counts for Omegaven-treated patients at baseline were 10.2 g/dL and 173 × 109/L, and by the end of the study these levels were 10.5 g/dL and 217 × 109/L, respectively. Adverse reactions associated with bleeding were experienced by 74 (39%) of Omegaven-treated patients.
Median glucose levels at baseline and the end of the study were 86 and 87 mg/dL for Omegaven-treated patients, respectively. Hyperglycemia was experienced by 13 (7%) Omegaven-treated patients.
Median triglyceride levels at baseline and the end of the study were 121 mg/dL and 72 mg/dL for Omegaven-treated patients respectively. Hypertriglyceridemia was experienced by 5 (3%) Omegaven-treated patients.
The triene:tetraene (Mead acid:arachidonic acid) ratio was used to monitor essential fatty acid status in Omegaven-treated patients only in Study 1 (n = 123) [see Warnings and Precautions (5.8)]. The median triene:tetraene ratio was 0.02 (interquartile range: 0.01 to 0.03) at both baseline and the end of the study. Blood samples for analysis may have been drawn while the lipid emulsion was being infused and patients received enteral or oral nutrition.
6.2 Postmarketing Experience
The following adverse reaction has been identified with use of Omegaven in another country. Because this reaction was reported voluntarily from a population of uncertain size, it is not possible to reliably estimate its frequency or establish a causal relationship to drug exposure.
Life-threatening hemorrhage following a central venous catheter change was reported in a 9-month-old infant with intestinal failure who received PN with Omegaven as the sole lipid source; he had no prior history of bleeding, coagulopathy, or portal hypertension.
7 DRUG INTERACTIONS
7.1 Antiplatelet Agents and Anticoagulants
Some published studies have demonstrated prolongation of bleeding time in patients taking antiplatelet agents or anticoagulants and oral omega-3 fatty acids. The prolongation of bleeding times reported in those studies did not exceed normal limits and there were no clinically significant bleeding episodes. Nonetheless, it is recommended to periodically monitor bleeding time in patients receiving Omegaven and concomitant antiplatelet agents or anticoagulants.
8 USE IN SPECIFIC POPULATIONS

Risk Summary
There are no available data on Omegaven use in pregnant women to establish a drug-associated risk of major birth defects, misc |
