Precautions for Clinolipid
Clinical Decompensation with Rapid Infusion of Intravenous Lipid Emulsion in Neonates and Infants
In the postmarketing setting, serious adverse reactions including acute respiratory distress, metabolic acidosis, and death have been reported in neonates and infants after rapid infusion of intravenous lipid emulsions. Hypertriglyceridemia was commonly reported.
Strictly adhere to the recommended total daily dosage; the hourly infusion rate should not exceed 0.75 mL/kg/hour [see Dosage and Administration (2.4)].
Preterm and small for gestational age infants have poor clearance of intravenous lipid emulsion and increased free fatty acid plasma levels following lipid emulsion infusion. The risk due to poor lipid clearance should be considered when administering intravenous lipid emulsions.
Carefully monitor the infant’s ability to eliminate the infused lipids from the circulation (e.g., measure serum triglycerides and/or plasma free fatty acid levels). If signs of poor clearance of lipids from the circulation occur, stop the infusion and initiate a medical evaluation [see Warnings and Precautions (5.5, 5.7) and Overdosage (10)].
Parenteral Nutrition-Associated Liver Disease and Other Hepatobiliary Disorders
Risk of Parenteral Nutrition-Associated Liver Disease
Parenteral nutrition-associated liver disease (PNALD), also referred to as intestinal failure-associated liver disease (IFALD), can present as cholestasis or hepatic steatosis, and may progress to steatohepatitis with fibrosis and cirrhosis (possibly leading to chronic hepatic failure). The etiology of PNALD is multifactorial; however, intravenously administered phytosterols (plant sterols) contained in plant-derived lipid emulsions, including CLINOLIPID, have been associated with development of PNALD.
Monitor liver tests in patients treated with CLINOLIPID and consider discontinuation or dosage reduction if abnormalities occur.
Other Hepatobiliary Disorders
Hepatobiliary disorders including cholecystitis and cholelithiasis have developed in some PN-treated patients without preexisting liver disease.
Monitor liver tests when administering CLINOLIPID. Patients developing signs of hepatobiliary disorders should be assessed early to determine whether these conditions are related to CLINOLIPID use.
Hypersensitivity Reactions
CLINOLIPID contains soybean oil and egg phospholipids, which may cause hypersensitivity reactions. Cross reactions have been observed between soybean and peanut. In postmarketing experience, anaphylaxis has been reported following CLINOLIPID administration [see Adverse Reactions (6.2)].
CLINOLIPID is contraindicated in patients with known hypersensitivity to egg, soybean, peanut, or any of the active or inactive ingredients in CLINOLIPID [see Contraindications (4)]. If a hypersensitivity reaction occurs, stop infusion of CLINOLIPID immediately and initiate appropriate treatment and supportive measures.
Infections
Lipid emulsions, such as CLINOLIPID, can support microbial growth and are an independent risk factor for the development of catheter-related bloodstream infections. To decrease the risk of infectious complications, ensure aseptic techniques are used for catheter placement, catheter maintenance, and preparation and administration of CLINOLIPID.
Monitor for signs and symptoms of infection including fever and chills, as well as laboratory test results that might indicate infection (including leukocytosis and hyperglycemia). Perform frequent checks of the intravenous catheter insertion site for edema, redness, and discharge.
Fat Overload Syndrome
Fat overload syndrome is a rare condition that has been reported with intravenous lipid formulations and is characterized by a sudden deterioration in the patient's condition (e.g., fever, anemia, leukopenia, thrombocytopenia, coagulation disorders, hyperlipidemia, hepatomegaly, deteriorating liver function, and central nervous system manifestations such as coma). A reduced or limited ability to metabolize lipids, accompanied by prolonged plasma clearance (resulting in higher lipid levels), may result in this syndrome. Although fat overload syndrome has been most frequently observed when the recommended lipid dose or infusion rate was exceeded, cases have also been described when the lipid formulation was administered according to instructions.
If signs or symptoms of fat overload syndrome occur, stop CLINOLIPID. The syndrome is usually reversible when the infusion of the lipid emulsion is stopped.
Refeeding Syndrome
Administering PN to severely undernourished patients may result in the refeeding syndrome, which is characterized by intracellular shift of potassium, phosphorus, and magnesium as the patients become anabolic. Thiamine deficiency and fluid retention may also develop. To prevent these complications, closely monitor severely malnourished patients and slowly increase their nutrient intake.
Hypertriglyceridemia
The use of CLINOLIPID is contraindicated in patients with hypertriglyceridemia with serum triglyceride concentrations >1,000 mg/dL.
Patients with conditions such as inherited lipid disorders, obesity, diabetes mellitus, or metabolic syndromes have a higher risk of developing hypertriglyceridemia with the use of CLINOLIPID. In addition, patients with hypertriglyceridemia may have worsening of their hypertriglyceridemia with administration of CLINOLIPID. Excessive dextrose administration may further increase such risk.
Evaluate patients’ capacity to metabolize and eliminate the infused lipid emulsion by measuring serum triglycerides before the start of infusion (baseline value) and regularly throughout treatment. If triglyceride levels are above 400 mg/dL in adults, stop the CLINOLIPID infusion and monitor serum triglyceride levels to avoid clinical consequences of hypertriglyceridemia such as pancreatitis.
To minimize the risk of new or worsening of hypertriglyceridemia, assess high-risk patients for their overall energy intake including other sources of lipids and dextrose, as well as concomitant drugs that may affect lipid and dextrose metabolism.
Aluminum Toxicity
CLINOLIPID contains no more than 25 mcg/L of aluminum.
The aluminum contained in CLINOLIPID may reach toxic levels with prolonged administration in patients with impaired kidney function. Preterm infants are at greater risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions that contain aluminum. Patients with impaired kidney function, including preterm infants, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day, accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration of total parenteral nutrition products.
Essential Fatty Acid Deficiency
In pediatric trials, EFAD was defined by calculating the Holman index (the triene [Mead acid] to tetraene [arachidonic acid] ratio; T:T ratio > 0.4). One patient treated with CLINOLIPID became at risk for EFAD (T:T ratio >0.2) after 14 days of treatment. No cases of biochemical EFAD and no cases of clinical EFAD were observed; however, the median treatment duration in three of the four pediatric trials was 15 days or less. There are insufficient data to determine whether CLINOLIPID can supply adequate amounts of essential fatty acids in patients who may need treatment for more than 15 days.
Monitor patients for laboratory evidence (e.g., abnormal fatty acid levels) and clinical symptoms of EFAD (e.g., skin manifestations, poor growth). Laboratory testing using the triene to tetraene ratio may not be adequate to diagnose EFAD, and assessment of individual fatty acid levels may be needed. Ensure patients are receiving recommended dosages of CLINOLIPID to prevent EFAD [see Dosage and Administration (2.4) and Description (11)].
Monitoring/Laboratory Tests
Routine Monitoring
Monitor fluid status closely in patients with pulmonary edema or heart failure.
Throughout treatment, monitor serum triglycerides [see Warnings and Precautions (5.7)], fluid and electrolyte status, serum osmolarity, blood glucose, liver and kidney function, blood count (including platelets), and coagulation parameters.
The lipids contained in CLINOLIPID may interfere with the results of some laboratory tests (e.g., hemoglobin, lactate dehydrogenase, bilirubin, oxygen saturation) if the blood is sampled before the lipids have cleared from the bloodstream. Conduct these tests at least 6 hours after stopping the infusion.
CLINOLIPID 20% contains Vitamin K that may counteract anticoagulant activity [see Drug Interactions (7)].
NONCLINICAL TOXICOLOGY
Carcinogenesis, Mutagenesis, Impairment of Fertility
Studies with CLINOLIPID have not been performed to evaluate the carcinogenic potential, mutagenic potential, or effects on fertility.
Animal Toxicology and/or Pharmacology
CLINOLIPID was evaluated in toxicity studies conducted in rats and dogs for up to 3 months. The principal signs of toxicity noted in the 3-month studies were:
- Slight hemolytic anemia at 12 g/kg/day in rats and at 6 g/kg/day in These doses in rats and dogs are 4 and 2 times higher, respectively, than the maximum recommended pediatric dose (3 g/kg/day) of CLINOLIPID.
- Dose-dependent decrease in urea levels in rats at 6 and 12 g/kg/day dose levels and in dogs at 3, 5 and 6 g/kg/day dose levels associated with decreased feed consumption.
- Hypercholesterolemia in dogs at 3, 5 and 6 g/kg/day dose levels.
- Hepatic pathology of lipid and pigmentary overload in male and female rats at 3, 6 and 12 g/kg/day dose levels and brownish-yellow pigmentation in vacuolated Kupffer cells in male and female dogs at 3, 4.5 and 6 g/kg/day dose levels with hepatocyte vacuolation in male dogs at 6 g/kg/day and female dogs at 4.5 and 6 g/kg/day dose levels.
- Splenic pigmentation and vacuolization in rats at 3, 6 and 12 g/kg/day dose levels, and dogs in 5 and 6 g/kg/day dose levels.
At doses of 3 g/kg/day, slight lipid and pigmentary overload of the liver and vacuolization of Kupffer cells were observed in rats and dogs. At a dose of 12 g/kg/day in rats, hepatocellular vacuolation, granulomatous inflammation of the liver, hepatocellular necrosis and hemosiderosis of the liver and lipid deposits and splenic hemosiderosis, were observed. In dogs, at a dose of 6 g/kg/day, brownish-yellow pigmentation in the Kupffer cells of liver and spleen, hyperplasia of vacuolated Kupffer cells, hepatocyte vacuolization, a slight increase in the number of lipid storage cells (Ito cells) in the liver and macrophage vacuolization of the spleen were observed.
