2.1 Preparation Prior to Administration

•

CLINIMIX E is available in a three port container configuration and a two port container configuration.

•

Three Port Container: the ports consist of one medication port, one additive port and one outlet port. Additives can be introduced to the container through the medication port and lipids through the additive port on the three port container.

•

Two Port Container: the ports consist of one medication port and one outlet port. Additives, including lipids, can be introduced to the container through the medication port on the two port container.

•

Tear protective overwrap at slit and remove solution container. Small amounts of moisture may be found on the solution container from water permeating from inside the container. The amount of permeated water is insufficient to affect the solution significantly. If larger amounts of water are found, the container should be checked for tears or leaks.

•

Inspect the container prior to activation. Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually. Evaluate the following:

•

If the outlet or additive port protectors are damaged, detached, or not present, discard container as solution path sterility may be impaired.

•

Check to ensure seal between chambers is intact, solutions are contained in separate chambers, and the content of the individual chambers is clear, colorless or slightly yellow. Discard if the seal is broken or if the solution is bright yellow or yellowish brown.

•

Check for minute leaks by separately squeezing each chamber. If external leaks or leakage between the chambers are found, discard solution as sterility or stability may be impaired.

•

Lipids and/or additives can be introduced to the container after opening seal between chambers. Because additives may be incompatible, evaluate all additions to the plastic container for compatibility. Activate chambers of container prior to introduction of additives. Mix thoroughly when additives have been introduced. Supplemental medication may be added with a 19 to 22 gauge needle through the medication port.

•

Calcium and phosphate ratios must be considered. Excess addition of calcium and phosphate, especially in the form of mineral salts, may result in the formation of calcium phosphate precipitates [see Warnings and Precautions (5.1)].

•

Inspect the container to ensure precipitates have not formed during the mixing or addition of additives. A slight yellow color does not alter the quality and efficacy of this product. If lipid has been added, ensure the emulsion has not separated. Separation of the emulsion can be visibly identified by a yellowish streaking or the accumulation of yellowish droplets in the mixed emulsion. Discard the admixture if any of the above are observed.

2.2 Important Administration Instructions

•

Set the vent to the closed position on a vented intravenous administration set to prevent air embolism.

•

Use a dedicated line without any connections to avoid air embolism.

•

CLINIMIX E is for intravenous infusion only into a central or peripheral vein. The choice of a central or peripheral venous route should depend on the osmolarity of the final infusate. Solutions with osmolarity of 900 mOsm/L or greater must be infused through a central catheter [see Warnings and Precautions (5.7)].

•

For central vein infusion only: CLINIMIX E 4.25/10, 5/15, 5/20, 8/10, 8/14

•

For central or peripheral vein infusion: CLINIMIX E 2.75/5 and 4.25/5

•

The solution should be inspected for precipitates before admixing, after admixing, and again before administration.

•

Use a 0.22 micron filter for administration of CLINIMIX E. If a lipid is also administered, use a 1.2 micron filter.

•

If lipid emulsion is added, do not use administration sets and lines that contain di-2-ethylhexyl phthalate (DEHP). Administration sets that contain polyvinyl chloride (PVC) components have DEHP as a plasticizer.

•

Ceftriaxone must not be administered simultaneously with calcium-containing intravenous solutions such as CLINIMIX E via a Y-site. However, in patients other than neonates, ceftriaxone and CLINIMIX E may be administered sequentially if the infusion lines are thoroughly flushed between infusions with a compatible fluid [see Contraindications (4), Warnings and Precautions (5.2)].

2.3 Instructions for Use

1.

Open by tearing protective overwrap at slit and remove solution container. The two port container includes an oxygen-absorbing sachet. Discard the oxygen-absorbing sachet after removal from the overwrap.

2.

To proceed with activation, the container should be at room temperature. Lay the room temperature container onto a flat surface. Grasp the container firmly on each side of the top of the container (Figure 1).

3.

Starting from the top, using some pressure, slowly roll the container to open seal between chambers as shown in Figure 2. Do not pull or rip the seal apart. The seal must be completely opened towards the port side of the container. The upper section of the seal towards the hanger side can remain unbroken.

4.

Mix the contents thoroughly by inverting the container upside down to ensure a homogenous admixture (Figure 3).

5.

Once the container is mixed, check for leaks.

6.

2.5 Dosing Considerations

•

The dosage of CLINIMIX E should be individualized based on the patient’s clinical condition (ability to adequately metabolize amino acids and dextrose), body weight and nutritional/fluid requirements, as well as additional energy given orally/enterally to the patient. Prior to initiating CLINIMIX E the following patient information should be reviewed: all concomitant medications, gastrointestinal function and laboratory data such as electrolytes (including magnesium, calcium, and phosphorus), glucose, urea/creatinine, liver panel, complete blood count and triglyceride level (if adding lipid emulsion). Refer to the complete prescribing information of lipid emulsion for dosing information.

•

CLINIMIX E formulations have varying concentrations of protein, carbohydrate and a standard concentration of electrolytes; thus infusion rates to achieve requirements will vary. Protein, caloric, fluid and electrolyte requirements all need to be taken into consideration when determining individual patient dosage needs.

•

The dosage selection is based only on the recommended protein requirements. The maximum dextrose infusion rates and calorie and fluid requirements must also be considered when determining the clinically appropriate infusion rate for patients.

•

CLINIMIX E meets the total nutritional requirements for protein and dextrose in stable patients, and can be individualized to meet specific needs with the addition of nutrients.

•

Total daily fluid requirements can be met beyond the volume of amino acids solution by supplementing with non-carbohydrate or carbohydrate-containing electrolyte solutions. In many patients, provision of adequate calories in the form of hypertonic dextrose may require the administration of exogenous insulin to prevent hyperglycemia and glycosuria.

•

Prior to administration of CLINIMIX E correct severe fluid, electrolyte and acid-base disorders.

•

Monitor levels of serum potassium during therapy. It may be necessary to add additional potassium to the CLINIMIX E admixture.

•

Lipid emulsion administration should be considered with prolonged use (more than 5 days) of CLINIMIX E in order to prevent essential fatty acid deficiency (EFAD). Serum lipids should be monitored for evidence of EFAD in patients maintained on fat-free parenteral nutrition. See prescribing information of lipid emulsion.

•

The flow rate should be increased gradually. The flow rate must be adjusted taking into account the dose being administered, the daily volume intake, and the duration of the infusion.

2.6 Recommended Dosage in Adults

 

The recommended daily nutritional requirements for protein and dextrose compared to the amount of nutrition provided by CLINIMIX E are shown in Table 1.

 

As indicated on an individual basis, maintenance vitamins, additional electrolytes, trace elements and other components (including lipids) should be administered as required to prevent deficiencies and complications from developing.

 

The maximum infusion rates in adult patients are show in Table 2.

In addition to meeting protein needs, the administration rate should be governed, especially during the first few day of therapy, by the patient’s tolerance to dextrose. Daily intake of amino acids and dextrose should be increased gradually to the maximum required dose as indicated by frequent determinations of blood glucose levels.

2.7 Dosage Modifications in Patients with Kidney Disease

Prior to administration, correct severe fluid or electrolyte imbalances. Closely monitor serum electrolyte levels and adjust the volume of CLINIMIX E administered as required [see Warnings and Precautions (5.11)].

Chronic kidney disease patients with less than nephrotic range proteinuria require 0.8 g of protein/kg/day. Chronic kidney disease patients with nephrotic range proteinuria require 0.8 g of protein/kg/day plus 1 g of protein for each gram of proteinuria. Patients needing dialysis should receive from 1.2 g of protein/kg/day up to a maximum of 2.5 g of protein/kg/day depending on the nutritional status and the dialysis modality. Serum electrolyte levels should be closely monitored. The CLINIMIX E dosage can be adjusted based on the severity of kidney disease, supplementing protein as indicated. If required, additional amino acids may be added to the CLINIMIX E container or infused separately. Compatibility of additions should be evaluated by a pharmacist and questions may be directed to Baxter.

2.8 Recommended Dosage in Pediatric Patients

The dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low weight infants, because of the increased risk of hyperglycemia/hypoglycemia [see Use in Specific Populations (8.4)]. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. The infusion rate and volume should be determined by the consulting physician experienced in pediatric intravenous fluid therapy.

In pediatric patients, CLINIMIX E is dosed on the basis of protein provided as amino acids. The recommended dosage, by age group is provided in Tables 3 - 6. Infusion rates are based on protein and do not take carbohydrates, fluid or electrolytes into consideration.

This product does not contain the amino acids cysteine and taurine, considered conditionally essential for neonates and infants. If possible, these amino acids should be added to this product if used in this pediatric population.

2.9 Discontinuation of CLINIMIX E injection

To reduce the risk of hypoglycemia after discontinuation, a gradual decrease in flow rate in the last hour of infusion should be considered.

5.1 Pulmonary Embolism due to Pulmonary Vascular Precipitates

Pulmonary vascular precipitates causing pulmonary vascular emboli and pulmonary distress have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes due to pulmonary embolism have occurred. Patients, especially those with hypophosphatemia, may require the addition of phosphate. To prevent hypocalcemia, calcium supplementation should always accompany phosphate administration. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution. Precipitation following passage through an in-line filter and suspected in vivo precipitate formation has also been reported. If signs of pulmonary distress occur, stop the infusion and initiate a medical evaluation. In addition to inspection of the solution [see Dosage and Administration (2.1, 2.2, 2.3, 2.4)], the infusion set and catheter should also periodically be checked for precipitates.

5.2 Precipitation with Ceftriaxone

Precipitation of ceftriaxone-calcium can occur when ceftriaxone is mixed with calcium-containing parenteral nutrition solutions, such as CLINIMIX E, in the same intravenous administration line. Do not administer ceftriaxone simultaneously with CLINIMIX E via a Y-site.

Deaths have occurred in neonates (less than 28 days of age) who received concomitant intravenous calcium-containing solutions with ceftriaxone resulting from calcium-ceftriaxone precipitates in the lungs and kidneys, even when separate infusion lines were used. CLINIMIX E is contraindicated in neonates receiving ceftriaxone [see Contraindications (4),Use in Specific Populations (8.4)].

In patients older than 28 days (including adults), ceftriaxone and CLINIMIX E may be administered sequentially if the infusion lines are thoroughly flushed between infusions with a compatible fluid.

5.3 Hypersensitivity Reactions

Hypersensitivity/infusion reactions including anaphylaxis have been reported with CLINIMIX E. Stop infusion immediately and treat patient accordingly if any signs or symptoms of a hypersensitivity reaction develop. Signs or symptoms may include: hypotension, hypertension, peripheral cyanosis, tachycardia, dyspnea, vomiting, nausea, urticaria, rash, pruritus, erythema, hyperhidrosis, pyrexia, and chills.

5.4 Risk of Infections

Patients who require parenteral nutrition are at high risk of infections because the nutritional components of these solutions can support microbial growth. Infection and sepsis may also occur as a result of the use of intravenous catheters to administer parenteral nutrition.

The risk of infection is increased in patients with malnutrition-associated immunosuppression, hyperglycemia exacerbated by dextrose infusion, long-term use and poor maintenance of intravenous catheters, or immunosuppressive effects of other concomitant conditions, drugs, or other components of the parenteral formulation (e.g., lipid emulsion).

To decrease the risk of infection, ensure aseptic technique in catheter placement and maintenance, as well as aseptic technique in the preparation and administration of the nutritional formula.

Monitor for signs and symptoms (including fever and chills) of early infections, including laboratory test results (including leukocytosis and hyperglycemia) and frequent checks of the parenteral access device and insertion site for edema, redness and discharge.

5.5 Refeeding Syndrome

Refeeding severely undernourished patients may result in refeeding syndrome, characterized by the intracellular shift of potassium, phosphorus, and magnesium as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. To prevent these complications, monitor severely undernourished patients and slowly increase nutrient intakes.

5.6 Hyperglycemia or Hyperosmolar Hyperglycemic State

When using CLINIMIX E in patients with diabetes mellitus, impaired glucose tolerance may worsen hyperglycemia. Administration of dextrose at a rate exceeding the patient’s utilization rate may lead to hyperglycemia, coma, and death. Patients with dehydration, resulting in a transient reduction in glomerular filtration rate and pre-renal azotemia, may be at greater risk of developing hyperosmolar hyperglycemic state. Monitor blood glucose levels and treat hyperglycemia to maintain optimum levels while administering CLINIMIX E. Insulin may be administered or adjusted to maintain optimal blood glucose levels during CLINIMIX E administration.

5.7 Vein Damage and Thrombosis

Solutions with osmolarity of 900 mOsm/L or greater must be infused through a central catheter. CLINIMIX E solutions containing more than 5% dextrose have an osmolarity greater than or equal to 900 mOsm/L. CLINIMIX E 4.25/10, 5/15, 5/20, 8/10 and 8/14 are indicated for administration into a central vein only, such as the superior vena cava [see Dosage and Administration (2.2)]. The infusion of hypertonic nutrient injections into a peripheral vein may result in vein irritation, vein damage, and/or thrombosis.

CLINIMIX E 2.75/5 and 4.25/5 are indicated for peripheral administration, or may be infused into a central vein [see Dosage and Administration (2.2)]. The primary complication of peripheral access is venous thrombophlebitis, which manifests as pain, erythema, tenderness or a palpable cord. Remove the catheter as soon as possible, if thrombophlebitis develops.

5.8 Hepatobiliary Disorders

Hepatobiliary disorders are known to develop in some patients without preexisting liver disease who receive parenteral nutrition, including cholecystitis, cholelithiasis, cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure. The etiology of these disorders is thought to be multifactorial and may differ between patients.

Increase in blood ammonia levels and hyperammonemia may occur in patients receiving amino acid solutions. In some patients this may indicate hepatic insufficiency or the presence of an inborn error of amino acid metabolism [see Contraindications (4)].

Monitor liver function parameters and ammonia levels. Patients developing signs of hepatobiliary disorders should be assessed early by a clinician knowledgeable in liver diseases in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.

5.9 Aluminum Toxicity

CLINIMIX E contains no more than 25 mcg/L of aluminum. The aluminum contained in CLINIMIX E 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, which 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.

5.10 Risk of Parenteral Nutrition Associated Liver Disease

Parenteral Nutrition Associated Liver Disease (PNALD) has been reported in patients who receive parenteral nutrition for extended periods of time, especially preterm infants, and can present as cholestasis or steatohepatitis. The exact etiology is unknown and is likely multifactorial. If CLINIMIX E treated patients develop liver test abnormalities consider discontinuation or dosage reduction.

5.11 Electrolyte Imbalance and Fluid Overload

Patients with abnormal renal function due to pre-renal azotemia, renal obstruction, or intrinsic kidney disease may be at increased risk of electrolyte and fluid volume imbalance. Patients with cardiac insufficiency due to left ventricular systolic dysfunction are susceptible to excess fluid accumulation. Use CLINIMIX E with caution in patients with cardiac insufficiency or kidney disease. CLINIMIX E dosage may require adjustment with specific attention to fluid, protein, and electrolyte content in these patients.

Monitor renal function parameters. Patients developing signs of kidney disease should be assessed early by a clinician knowledgeable in kidney disease in order to determine the appropriate CLINIMIX E dosage and other treatment options.

5.12 Monitoring/Laboratory Tests

Monitor fluid and electrolyte status, serum osmolarity, blood glucose, liver and kidney function, blood count and coagulation parameters throughout treatment. In situations of severely elevated electrolyte levels, stop CLINIMIX E until levels have been corrected.

7.1 Drugs that Can Cause Hyperkalemia

Because of its potassium content, CLINIMIX E should be administered with caution in patients treated with agents or products that can cause hyperkalemia or increase the risk of hyperkalemia, such as potassium sparing diuretics (amiloride, spironolactone, triamterene), with ACE inhibitors, angiotensin II receptor antagonists, or the immunosuppressants tacrolimus and cyclosporine.

8.1 Pregnancy

8.2 Lactation

8.4 Pediatric Use

Safety and effectiveness of CLINIMIX E in pediatric patients have not been established by adequate and well-controlled studies. Use of dextrose, amino acid infusions and electrolytes in pediatric patients is based on clinical practice [see Dosage and Administration (2.8)].

Deaths have occurred in neonates (28 days of age or younger) who received concomitant intravenous calcium-containing solutions with ceftriaxone resulting from calcium-ceftriaxone precipitates in the lungs and kidneys, even when separate infusion lines were used. CLINIMIX E is contraindicated in neonates receiving ceftriaxone [see Contraindications (4), Warnings and Precautions (5.2)].

Newborns, especially those born premature and with low birth weight, are at increased risk of developing hypo – or hyperglycemia and therefore need close monitoring during treatment with intravenous glucose solutions to ensure adequate glycemic control in order to avoid potential long term adverse effects. Hypoglycemia in the newborn can cause prolonged seizures, coma and brain damage. Hyperglycemia has been associated with intraventricular hemorrhage, late onset bacterial and fungal infection, retinopathy of prematurity, necrotizing enterocolitis, bronchopulmonary dysplasia, prolonged length of hospital stay, and death. Plasma electrolyte concentrations should be closely monitored in the pediatric population as this population may have impaired ability to regulate fluids and electrolytes.

Because of immature renal function, preterm infants receiving prolonged treatment with CLINIMIX E, may be at risk of aluminum toxicity [see Warnings and Precautions (5.9)].

Patients, including pediatric patients, may be at risk for Parenteral Nutrition Associated Liver Disease (PNALD) [see Warnings and Precautions (5.10)].

Hyperammonemia is of special significance in infants (birth to two years). This reaction appears to be related to a deficiency of the urea cycle amino acids of genetic or product origin. It is essential that blood ammonia be measured frequently in infants [see Warnings and Precautions (5.8)].

8.5 Geriatric Use

Clinical studies of CLINIMIX E did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from other younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy.

12.1 Mechanism of Action

CLINIMIX E is used as a supplement of nutrition in patients, providing macronutrients (amino acids and dextrose) and micronutrients (electrolytes) parenterally.

The amino acids provide the structural units that make up proteins and are used to synthesize proteins and other biomolecules or are oxidized to urea and carbon dioxide as a source of energy.

The administered dextrose is oxidized to carbon dioxide and water, yielding energy.

12.3 Pharmacokinetics

The disposition of infused amino acids, dextrose, and electrolytes are essentially the same as those absorbed from ordinary food.
