Numeta G19%E emulsion for infusion

Numeta G19%E is indicated for parenteral nutrition in children older than 2 years and adolescents 16-18 years old when oral or enteral nutrition is not possible, insufficient or contraindicated.

Posology

The dosage depends on energy expenditure, the patient's weight, age, clinical status, and on the ability to metabolize the constituents of Numeta, as well as on additional energy or proteins given orally/enterally. Total electrolyte and macronutrient composition is dependent on the number of activated chambers (See section 2).

The maximum daily dose should not be exceeded. Due to the static composition of the multi-chamber bag, the ability to simultaneously meet all nutrient needs of the patient may not be possible. Clinical situations may exist where patients require amounts of nutrients varying from the composition of the static bag.

The maximal recommended hourly rate of infusion and volume per day depend on the constituent. The first of these limits to be reached sets the maximum daily dose. The guidelines for maximal recommended hourly rate of infusion and volume per day are:

^a Limiting parameter according to ESPEN-ESPGHAN guidelines

Method of administration

For instructions for preparation, and handling of the solution/emulsion for infusion, see section 6.6.

The solution (in bags and administration sets) should be protected from light exposure from point of admixture through administration (see section 4.4 and 6.6).

Use of a 1.2 micron filter is recommended for administration of Numeta G19%E.

Due to its high osmolarity, undiluted Numeta G19%E can only be administered through a central vein. However, sufficient dilution of Numeta G19%E with water for injection lowers the osmolarity and allows peripheral infusion.

The table below indicates the minimum volume of water for injection to be added to the activated bag in order to achieve the target osmolarity for peripheral administration. It should be noted that any other addition made to the activated bag will modify the final osmolarity.

^aThe dilution of Numeta G19%E 2-in-1 admixture for peripheral administration for children and adolescents up to 18 years is not appropriate because the volume of water which would be required to be added exceeds bag capacity and may exceed patients' daily fluid requirements.

The flow rate should be increased gradually during the first hour. Upon discontinuation of Numeta G19%E, the flow rate should be decreased gradually during the last hour. The administration flow rate must be adjusted taking into account the dose being administered, the daily volume intake, and the duration of the infusion, see section 4.9.

The same bag should not be activated, hung and infused longer than 24 hours. Cyclic infusions should be managed according to the patient's metabolic tolerance.

Treatment with parenteral nutrition may be continued for as long as is required by the patient's clinical conditions.

This product contains electrolytes and may be further supplemented using commercial electrolyte preparations according to the physician's judgment and the clinical needs of the patient, see section 6.6.

Vitamins and trace elements can be added according to the physician's judgment and the clinical needs of the patient, see section 6.6.

The general contraindications for administering Numeta as an activated 2 chamber bag for intravenous infusion are as follows:

• Hypersensitivity to egg, soy or peanut proteins, or to any of the active substances, excipients listed in section 6.1, or components of the container

• Congenital abnormality of the amino acid metabolism

• Pathologically elevated plasma concentrations of sodium, potassium, magnesium, calcium and/or phosphorus

• Severe hyperglycaemia

The addition of lipids (administering Numeta G19%E as an activated 3 chamber bag for intravenous emulsion) is contraindicated in the following additional clinical situations:

• Severe hyperlipidaemia, or severe disorders of lipid metabolism characterized by hypertriglyceridemia

The infusion must be stopped immediately if any signs or symptoms of an allergic reaction (such as fever, sweating, shivering, headache, skin rashes, or dyspnea) develop.

Numeta G19%E contains glucose produced from cornstarch. Therefore, Numeta G19%E should be used with caution in patients with known allergy to corn or corn products.

In patients of any age (including adults), ceftriaxone must not be mixed or administered simultaneously with any intravenous calcium-containing solutions, including Numeta G19%E, even via different infusion lines or at different infusion sites because of the risk of precipitation of ceftriaxone-calcium salt.

However, in patients older than 28 days of age ceftriaxone and calcium-containing solutions may be administered sequentially one after another if infusion lines at different sites are used or if the infusion lines are replaced or thoroughly flushed between infusions with physiological salt-solution to avoid precipitation.

Pulmonary vascular precipitates causing pulmonary vascular embolism and respiratory distress have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes have occurred. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates (see section 6.2). Suspected precipitate formation in the blood stream have also been reported.

In addition to inspection of the solution, the infusion set and catheter should also periodically be checked for precipitates.

If signs of respiratory distress occur, the infusion should be stopped and medical evaluation initiated.

No additions to the bag should be made without first checking the compatibility, as formation of precipitates or destabilization of the lipid emulsion could result in vascular occlusion, see sections 6.2 and 6.6.

Infection and sepsis may occur as a result of the use of intravenous catheters to administer parenteral formulations, or poor maintenance of catheters. Immunosuppressive effects of illness, or drugs, may promote infection and sepsis. Careful symptomatic and laboratory monitoring for fever/chills, leukocytosis, technical complications with the access device, and hyperglycaemia can help recognize early infections. Patients who require parenteral nutrition are often predisposed to infectious complications due to malnutrition and/or their underlying disease state. The occurrence of septic complications can be decreased with heightened emphasis on aseptic technique in catheter placement, maintenance, as well as aseptic technique in nutritional formula preparation.

Fat overload syndrome has been reported with other parenteral nutrition products. A reduced or limited ability to metabolize the lipids contained in Numeta, or an overdose, may result in a “fat overload syndrome” (see section 4.8 and 4.9).

Refeeding severely undernourished patients may result in the refeeding syndrome that is characterized by the shift of potassium, phosphorus, and magnesium intracellularly as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. Careful and slow initiation of parenteral nutrition is recommended, with close monitoring of fluids, electrolytes, trace elements and vitamins.

Numeta must only be administered through a central vein, except if appropriate dilution is performed (see section 4.2). When making additions to the formulation, the final osmolarity of the mixture must be calculated before administration via peripheral vein to avoid vein irritation or tissue damage in the case of extravasation of the solution. Peripheral administration of Numeta has resulted in extravasation leading to soft tissue injury and skin necrosis. Do not connect bags in series in order to avoid air embolism due to possible residual gas contained in the primary bag.

Lipids, vitamins, additional electrolytes and trace elements should be administered as required.

PRECAUTIONS

Do not add other medicinal products or substances to one of the three chambers of the bag or to the reconstituted solution/emulsion without first confirming their compatibility and the stability of the resulting preparation (in particular, stability of the lipid emulsion) (see sections 6.2 and 6.6).

Numeta G19 should be protected from light from the point of admixture through administration (see section 6.6).

Routinely monitor water and electrolyte balance, serum osmolarity, serum triglycerides, acid/base balance, blood glucose, liver and kidney function, blood count including platelets, and coagulation parameters throughout treatment.

In case of unstable conditions (for example, following severe post-traumatic conditions, uncompensated diabetes mellitus, acute phase of circulatory shock, acute myocardial infarction, severe metabolic acidosis, severe sepsis and hyperosmolar coma) delivery of Numeta G19%E should be monitored and adjusted to meet the clinical needs of the patient.

Cardiovascular

Use with caution in patients with pulmonary edema or heart failure. Fluid status should be closely monitored.

Renal

Use with caution in patients with renal insufficiency. Fluid and electrolyte status should be closely monitored in these patients.

Severe water and electrolyte equilibration disorders, severe fluid overload states, and severe metabolic disorders should be corrected before starting the infusion.

Hepatic/Gastrointestinal

Use with caution in patients with severe liver insufficiency, including cholestasis, or elevated liver enzymes. Liver function parameters should be closely monitored.

Endocrine and Metabolism

Metabolic complications may occur if the nutrient intake is not adapted to the patient's requirements, or the metabolic capacity of any given dietary component is not accurately assessed. Adverse metabolic effects may arise from administration of inadequate or excessive nutrients or from inappropriate composition of an admixture for a particular patient's needs.

Serum triglyceride concentrations and the ability of the body to metabolize lipids must be checked regularly. If a lipid metabolism abnormality is suspected, monitoring of serum triglycerides is recommended as clinically necessary.

In the event of hyperglycemia, the infusion rate of Numeta G19%E must be adjusted and/or insulin administered, see section 4.9.

Hematologic

Use with caution in patients with severe blood coagulation disorders. Blood count and coagulation parameters should be closely monitored.

No pharmacodynamic interaction studies have been performed with Numeta G19%E.

Numeta G19%E must not be administered simultaneously with blood through the same infusion tubing because of the risk of pseudoagglutination.

In patients of any age (including adults), ceftriaxone must not be mixed or administered simultaneously with intravenous calcium-containing solutions, including Numeta G19%E, even via different infusion lines or at different infusion sites because of the risk of precipitation of ceftriaxone-calcium salt (see section 4.4).

However, in patients older than 28 days of age ceftriaxone and calcium-containing solutions may be administered sequentially one after another if infusion lines at different sites are used or if the infusion lines are replaced or thoroughly flushed between infusions with physiological salt-solution to avoid precipitation.

Olive and soybean oil have a natural content of vitamin K1 that may counteract the anticoagulant activity of coumarin (or coumarin derivatives including warfarin).

Due to the potassium content of Numeta G19%E special care should be taken in patients simultaneously treated with potassium sparing diuretics (amiloride, spironolactone, triamterene) or with ACE inhibitors, angiotensin II receptor antagonists, or the immunosuppressants tacrolimus and cyclosporine in view of the risk of hyperkalemia

The lipids contained in this emulsion may interfere with the results of certain laboratory tests (for example, bilirubin, lactate dehydrogenase, oxygen saturation, blood hemoglobin) if the blood sample is taken before the lipids are eliminated. Lipids are generally eliminated after a period of 5 to 6 hours when no additional lipids are administered.

Please also refer to section 6.2 “Incompatibilities”.

There are no data from the use of Numeta in pregnant or lactating women. Physicians should carefully consider the potential risks and benefits for each specific patient before prescribing Numeta.

Not relevant.

4.8.1 Adverse Reactions from Clinical Trials and Post-marketing experience

The safety and administration of Numeta was assessed in a single phase III study. One hundred and fifty nine (159) paediatric patients were included in the study and received Numeta.

The pooled data from clinical trials and the postmarketing experience indicate the following adverse drug reactions (ADRs) related to Numeta:

^a Blood samples drawn during the infusion (without fasting conditions).

^b Frequency is based upon the following categories: Very Common (≥1/10); Common (≥1/100 - <1/10), Uncommon (≥1/1,000 - <1/100), Rare (≥1/10,000 - <1/1,000), Very Rare (<1/10,000), Not known (cannot be estimated based on available data).

^c These adverse reactions have been reported only for Numeta G13%E Preterm and G16%E when peripherally administered with insufficient dilution (see Section 4.4)

4.8.2 Other (Class) Reactions

The following adverse reactions have been reported with other parenteral nutrition admixtures:

• Fat overload syndrome: may be caused by inappropriate administration (e.g. overdose and/or infusion rate higher than recommended, see section 4.9); however the signs and symptoms of this syndrome may also occur when the product is administered according to instructions. The reduced or limited ability to metabolize the lipids contained in Numeta G19%E accompanied by prolonged plasma clearance may result in a “fat overload syndrome”. This syndrome is associated with a sudden deterioration in the patient's clinical condition and is characterized by findings such as hyperlipidemia, fever, liver fatty infiltration (hepatomegaly), deteriorating liver function, anemia, leukopenia, thrombocytopenia, coagulation disorders, acute respiratory distress, metabolic acidosis, and central nervous system manifestations (e.g. coma). The syndrome is usually reversible when the infusion of the lipid emulsion is stopped

• Pulmonary vascular precipitates (pulmonary vascular embolism and respiratory distress) (see section 4.4).

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme: website: www.mhra.gov.uk/yellowcard

In the event of inappropriate administration (overdose, and/or infusion rate higher than recommended), nausea, vomiting, shivering, electrolyte disturbances and signs of hypervolemia or acidosis may occur and result in fatal consequences. In such situations, the infusion must be stopped immediately. If medically appropriate, further intervention may be indicated.

Hyperglycaemia, glucosuria, and hyperosmolar syndrome may develop if the glucose infusion rate exceeds clearance.

An overdose or reduced or limited ability to metabolize lipids may result in fat overload syndrome, the results of which are usually reversible after infusion of the lipid emulsion is stopped, see section 4.8. In neonates and infants, the fat overload syndrome has been associated with metabolic acidosis and respiratory distress.

There is no specific antidote for overdose. Emergency procedures should be general supportive measures, with particular attention to respiratory and cardiovascular systems. In some serious cases, hemodialysis, hemofiltration, or hemodiafiltration may be necessary. Severe cases of fat overload syndrome treated with exchange transfusions have been reported in the literature.

Close biochemical monitoring is essential and specific abnormalities should be treated appropriately.

Pharmacotherapeutic group: Solutions for parenteral nutrition/combination

ATC Code: B05 BA10

The content of nitrogen (20 L-series amino acids, including 8 essential amino acids) in Numeta and energy (glucose and triglycerides) enables maintenance of an adequate nitrogen/energy balance. Nitrogen and energy are required for normal functioning of all cells in the body, and are important for protein synthesis, growth, wound healing, immune function, muscle function, and many other cellular activities.

This formulation also contains electrolytes.

The amino acids profile is as follows:

• Essential amino acids/total amino acids: 47.5%

• Branched-chain amino acids/total amino acids: 24.0%

The lipid emulsion included in Numeta is a mixture of refined olive oil and refined soybean oil (ratio 80/20 approximately), with the following relative distribution of fatty acids:

• 15% saturated fatty acids (SFA)

• 65% monounsaturated fatty acids (MUFA)

• 20% polyunsaturated fatty acids (PUFA)

The phospholipid/triglyceride ratio is 0.06. The moderate essential fatty acid (EFA) content improves the status of their upper derivatives while correcting EFA deficiency.

Olive oil contains significant amounts of alpha-tocopherol which, when combined with a moderate PUFA intake, contributes to vitamin E status and is important for limiting lipid peroxidation.

The carbohydrate source is glucose. Glucose is a primary source of energy in the body.

The ingredients of the emulsion for infusion (amino acids, electrolytes, glucose, lipids) are distributed, metabolized and eliminated in the same way as if they had been administered individually. The product is given intravenously and is thus 100% bioavailable and the constituents are distributed to and metabolized by all cells in the body.

Preclinical studies performed on the components of the triple chamber bag have revealed no additional risks to those already mentioned in other sections of the SmPC.

Animal studies with Numeta (double or triple chamber combinations) have not been conducted.

^a for pH adjustment

In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products, see Section 6.6.

As with any parenteral nutrition admixture, 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.

In patients of any age ceftriaxone must not be mixed or administered simultaneously with intravenous calcium-containing solutions, including Numeta, even via different infusion lines or at different infusion sites because of the risk of precipitation of ceftriaxone-calcium salt.

Due to the risk of precipitation, Numeta G19%E should not be administered through the same infusion line together with ampicillin, fosphenytoin or furosemide.

Numeta G19%E must not be administered simultaneously with blood through the same infusion tubing, see section 4.5.

Numeta G19%E contains calcium ions which pose additional risk of coagulation precipitates in citrate-anticoagulated/preserved blood or components.

24 months

Shelf life after reconstitution

It is recommended that the product be used immediately after the non-permanent seals between the two or three chambers have been opened. However, stability data of the reconstituted mixtures supports 7 days between 2°C and 8°C followed by 48 hours at 30°C.

Shelf life after supplementation (electrolytes, trace elements, vitamins, water):

For specific admixtures in-use stability of the Numeta formulation has been demonstrated for 7 days between 2°C and 8°C followed by 48 hours at 30°C.

From a microbiological point of view, the product should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C, unless reconstitution /dilution /supplementation has taken place in controlled and validated aseptic conditions.

Please also refer to section 4.2 “Posology and method of administration” and section 6.6 “Special precautions for disposal and other handling”.

Do not freeze.

Store in overpouch.

The three-chamber full non-PVC bag consists of the following components:

• A multi-layer plastic sheeting.

• A port tube on the compartment containing the lipid emulsion. It is sealed off after filling to prevent additions to this chamber.

• Two port tubes on the amino acid solution and glucose solution chambers.

All components are free of natural latex rubber.

To prevent air contact, the bag is packaged in an oxygen barrier overpouch that contains an oxygen absorber sachet and an oxygen indicator.

Available pack sizes:

1000 mL bags: 6 units per cardboard box

1 bag of 1000 mL

Not all pack sizes may be marketed

For single use only.

Do not use damaged bags.

Confirm the integrity of the bag and non-permanent seals.

Only use if the amino acid and glucose solutions are clear, colourless or slightly yellow and free from particles, and if the lipid emulsion is homogenous with a milky appearance.

Use of a 1.2 micron filter is recommended for administration of Numeta G19%E.

Before opening the overpouch, check the colour of the oxygen indicator.

• Compare it to the reference colour printed next to the OK symbol and shown in the printed area of the indicator label.

• Do not use the product if the colour of the oxygen indicator does not correspond to the reference color printed next to the OK symbol.

Figures 1 and 2 illustrate how to remove the protective overpouch. Discard the overpouch, oxygen indicator and oxygen absorber.

Preparation of the mixed emulsion:

• Ensure that the product is at room temperature when breaking the non-permanent seals.

• Place bag onto a flat clean surface.

Activation of the 3CB (breaking two non-permanent seals)

Step 1: Start rolling the bag from the D-hanger side.

Step 2: Apply pressure until peal seals open.

Step 3: Change direction by rolling the bag towards the D-hanger.

Continue until the seal is completely opened

Proceed the same way to complete the opening of the second peel seal.

Step 4: Turn the bag over at least three times to mix the contents thoroughly.

The appearance of the mixed solution should be a milky-white emulsion.

Step 5: Remove the protective cap from the administration site and insert the IV administration set.

Activation of the 2CB (breaking the non-permanent seal between the Amino Acids and Glucose chambers)

Step 1: To break only the amino acids/glucose peel seal, start rolling the bag from the D-hanger corner of the seal separating the amino acids and glucose chambers and apply pressure to open the seal separating the glucose and amino acids compartments.

Step 2: Place the bag such that the lipid emulsion compartment is nearest to the operator and roll the bag while protecting the lipid emulsion compartment in the palms of the hands.

Step 3: With one hand, apply pressure by rolling the bag towards the tubes.

Step 4: Then change direction by rolling the bag towards the D-hanger, pressing with the other hand, continuing until the seal separating the amino acids and glucose solutions is completely opened.

Step 5: Turn the bag over at least three times to mix the content thoroughly. The appearance of the mixed solution should be clear, colorless or slightly yellow.

Step 6: Remove the protective cap from the administration site and insert the IV administration set.

Addition of additives

Admixtures including trace elements and vitamins should be protected from light, from the point of admixture through administration. Exposure to ambient light generates peroxides and other degradation products that can be reduced by photoprotection (see section 4.4).

Compatible additives may be added via the injection site into the reconstituted mixture (after the non-permanent seals have been opened and after the contents of the two or three chambers have been mixed).

Vitamins may also be added into the glucose chamber before the mixture is reconstituted (before opening the non-permanent seals and before mixing the solutions and the emulsion).

Possible additions of commercially available trace element solutions (identified as TE1, TE2, and TE4), vitamins (identified as lyophilizate V1 and emulsion V2), and electrolytes in defined quantities are shown in Tables 1-6.
