What is in this leaflet

This leaflet answers some of the more common questions about Carbaglu.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Carbaglu against the benefits he/she expects it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with your medicine. You may need to read this again.

What CARBAGLU is used for

Carbaglu is used to eliminate excessive levels of ammonia, referred to as hyperammonaemia. The high levels of ammonia in the blood may be caused by the lack of a specific liver enzyme called N-acetyl glutamate synthase (NAGS) or due to isovaleric acidaemia, methylmalonic acidaemia or propionic acidaemia.

High levels of ammonia in the blood are toxic for the brain and leads in severe cases, to reduced levels of consciousness and coma.

Some people are born with inherited diseases that cause some of the body’s enzymes to be missing or defective. The deficiency of NAGS is a rare disorder and results in patients not being able to eliminate nitrogen waste from the body which builds up after eating protein. This disorder persists for life and therefore the need for this treatment is lifelong.

Isovaleric acidaemia, methylmalonic acidaemia and propionic acidaemias are rare disorders that can inhibit NAGS and cause episodes of hyperammonaemia. The treatment of elevated ammonia in these disorders is required during these episodes.

Carbaglu helps the body’s natural process to eliminate ammonia by triggering the enzymes required to convert this to urea. This is eliminated from the body in urine.

Ask your doctor if you have any questions about why Carbaglu has been prescribed for you.

This medicine is available only with a doctor’s prescription.

Before your doctor gives you CARBAGLU

Tell your doctor if you:

Have allergies to any medicines
Are taking or using any other medicines. These include medicines bought from pharmacies, supermarkets and health food stores
Have any other medical conditions
Are pregnant or breast feeding.

If you want further information, consult your doctor.

How to take CARBAGLU

Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in this leaflet.

Your doctor may discuss with you the need to be on a restricted diet while you take Carbaglu.

If you do not understand the instructions, ask your doctor or pharmacist for help.

Your doctor will evaluate your individual responsiveness to Carbaglu before initiating any long term treatment.

The dose will be individually adjusted in order to maintain normal ammonia plasma levels.

Once the bottle containing the Carbaglu tablets has been opened, the tablets can be used for 3 months. Write the date when the bottle was first opened in the space provided on the bottle label.

How much to take

Each tablet contains 200mg.

The normal initial dose of Carbaglu is 100mg per kilogram of body weight per day. This dose maybe increased to 250 mg per kilogram of body weight per day.

For patients suffering from NAGS deficiency, in the long term, the daily dose usually ranges from 10 mg to 100 mg per kilogram of body weight. The total daily dose should be divided into 2 to 4 doses and round to the nearest 100 mg (half a Carbaglu tablet).

Your doctor may also recommend other therapies to help lower your ammonia levels.

Always consult your doctor with questions about your prescribed dose.

How to take it

Carbaglu tablets should not be swallowed whole or crushed.

Adults

Each 200 mg tablet should be dispersed in 5 to 10 ml of water and taken immediately.

Carbaglu tablets do not dissolve completely in water and undissolved particles of the tablet may remain in the mixing container. To ensure complete delivery of the dose, rinse the mixing container with additional volumes of water and swallow the contents immediately.

The suspension may taste slightly acidic.

Children

Each 200 mg tablet should be dispersed in a minimum of 2.5 ml of water. For swallowing using a syringe, draw up the volume of the liquid using an oral syringe and administer immediately. The syringe may be refilled with a small amount of water (1 – 2 mL) and administered.

For use with a nasogastric tube, the dose is given in the same way as above, with the tube flushed with water after administration.

When to take it

Carbaglu treatment should be initiated under the supervision of a doctor and given before meals or feeding.

How long to take it

Take Carbaglu for as long as your doctor tells you.

Carbaglu helps to lower your levels of ammonia in the blood, but it does not cure your condition.

If you forget to take it

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, talk to your doctor or pharmacist.

If you take too much of it (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 764 766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Carbaglu. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking CARBAGLU

Things you must do

Your doctor may ask you to have your liver, kidney, heart functions and blood tested from time to time to make sure the medicine is working to prevent unwanted side effects.

Your blood ammonia levels also need to be checked regularly while you are taking this medicine.

If you become pregnant while you are taking Carbaglu, contact your doctor immediately.

If you are about to be started on any new medication, remind your doctor and pharmacist that you are taking Carbaglu.

Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.

Things you must not do

Do not give Carbaglu to anyone else even if they have the same condition as you.

Do not take Carbaglu to treat any other complaints unless your doctor tell you.

Side Effects

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Do not be alarmed by the list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if

Tell your doctor or pharmacist if you notice any of the following and they worry you:

Increased sweating
Slow heart beat
Diarrhoea
Abdominal Pain
Fever or high temperature
Vomiting.

After taking CARBAGLU

BRAND INFORMATION

Brand name

Carbaglu

Active ingredient

Carglumic acid

Schedule

1 Name of Medicine

Carglumic acid.

2 Qualitative and Quantitative Composition

Carglumic acid is a white crystalline powder, soluble in boiling water, slightly soluble in cold water, practically insoluble in organic solvents (cyclohexane, dichloromethane, ether).
Carbaglu contains 200 mg of carglumic acid as the active ingredient. For the list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Carbaglu is a dispersible tablet containing 200 mg of carglumic acid. The tablets are white and elongated and can be divided into equal halves.

4 Clinical Particulars

4.1 Therapeutic Indications

Carbaglu is indicated in treatment of:
hyperammonaemia due to N-acetylglutamate synthase primary deficiency;
hyperammonaemia due to organic acidaemias such as hyperammonaemia due to isovaleric acidaemia, hyperammonaemia due to methylmalonic acidaemia, hyperammonaemia due to propionic acidaemia.

4.2 Dose and Method of Administration

Carbaglu treatment should be initiated under the supervision of a physician experienced in the treatment of metabolic disorders.
Any episode of acute symptomatic hyperammonaemia should be treated as a life threatening emergency and may be started as early as the first day of life. Treatment of hyperammonaemia may require dialysis, preferably hemodialysis, to remove a large burden of ammonia. Uncontrolled hyperammonaemia can rapidly result in brain injury/ damage or death, and prompt use of all therapies necessary to reduce plasma ammonia levels is essential.
Plasma levels of ammonia and amino acids should be maintained within normal limits. Ongoing monitoring of neurological and cardiac status, laboratory tests (renal, hepatic, haematological) and clinical responses in patients receiving carglumic acid is crucial to assess patient response.
Carbaglu tablets should not be swallowed whole or crushed. Disperse Carbaglu tablets in water immediately before use. Carbaglu is for oral administration only.

Adult dosage.

The recommended initial dose for acute hyperammonaemia is 100 mg/kg/day to 250 mg/kg/day. Concomitant administration of other ammonia lowering therapies is recommended during acute decompensations. Dosing should be titrated based on individual patient plasma ammonia levels and clinical symptoms.
The recommended maintenance dose should be titrated to target normal plasma ammonia level for age.
In the long-term, the dose should be individually adjusted to maintain adequate metabolic control (normal plasma ammonia).
The total daily dose should be divided into 2 to 4 doses and rounded to the nearest 100 mg (i.e. half a Carbaglu tablet).

Paediatric dosage.

The recommended initial dose for acute hyperammonaemia is 100 mg/kg/day to 250 mg/kg/day. Concomitant administration of other ammonia lowering therapies is recommended during acute decompensations. Dosing should be titrated based on individual patient plasma ammonia levels and clinical symptoms.
As with the use in adults, the recommended maintenance dose should be titrated to target normal plasma ammonia level for age.
In the long term, the dose should be individually adjusted to maintain adequate metabolic control (normal plasma ammonia).
The total daily dose should be divided into 2 to 4 doses.

Carglumic acid responsiveness test.

It is recommended to test individual responsiveness to Carbaglu before initiating any long-term treatment. As examples:
in a comatose child, start with a dose of 100 to 250 mg/kg/day and measure ammonia plasma concentration at least before each administration; it should normalise within a few hours after starting Carbaglu;
in a patient with moderate hyperammonaemia, administer a test dose of 100 to 200 mg/kg/day for 3 days with a constant protein intake and perform repeated determinations of ammonia plasma concentration (before and 1 hour after a meal); adjust the dose in order to maintain normal ammonia plasma levels.

Administration.

Oral administration in adults.

Carbaglu tablets should not be swallowed whole or crushed. Disperse Carbaglu tablets in water immediately before use.
Each 200 mg tablet should be dispersed in 5-10 mL of water and taken immediately. The suspension has a slightly acidic taste. Carbaglu tablets do not dissolve completely in water and undissolved particles of the tablet may remain in the mixing container. To ensure complete delivery of the dose, the mixing container should be rinsed with additional volumes of water (5-10 mL) and the contents swallowed immediately.
For patients who have a nasogastric tube in place, Carbaglu should be administered as follows:
Mix each 200 mg tablet in 5-10 mL of water. Shake gently to allow for quick dispersal.
Administer the dispersion immediately through the nasogastric tube.
Flush with additional water to clear the nasogastric tube.
Based on pharmacokinetic data and clinical experience, it is recommended to divide the total daily dose into two to four doses to be given before meals or feedings. The breaking of the tablets in halves allows most of the required posology adjustments. Occasionally, the use of quarter tablets may also be useful to adjust the posology prescribed by the physician.

Oral administration using an oral syringe in paediatrics.

For administration via oral syringe, Carbaglu should be administered as follows:
Mix each 200 mg tablet in 2.5 mL of water to yield a concentration of 80 mg/mL in a mixing container. Shake gently to allow for quick dispersal.
Draw up the appropriate volume of dispersion in an oral syringe and administer immediately. Discard the unused portion.
Refill the oral syringe with a minimum volume of water (1-2 mL) and administer immediately.

Nasogastric tube administration in paediatrics.

For patients who have a nasogastric tube in place, Carbaglu should be administered as follows:
Mix each 200 mg tablet in 2.5 mL of water to yield a concentration of 80 mg/mL in a mixing container. Shake gently to allow for quick dispersal.
Draw up the appropriate volume of dispersion and administer immediately through a nasogastric tube. Discard the unused portion.
Flush with additional water to clear the nasogastric tube.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients.
Breastfeeding during the use of carglumic acid is contraindicated.

4.4 Special Warnings and Precautions for Use

Cardiotoxicity and hepatotoxicity.

Due to the small dataset, any association between carglumic acid and cardiotoxicity or hepatotoxicity cannot be reliably determined. Therefore, cardiac and hepatic function monitoring is advised during treatment with carglumic acid.

Nutritional management.

Protein restriction during acute phase and protein supplementation during maintenance phase may be indicated. Specialised advice may be sought.

Use in the elderly.

No data is available regarding the administration of carglumic acid in the elderly.

Paediatric use.

See Section 4.2 Dose and Method of Administration.

Effects on laboratory tests.

Plasma levels of ammonia and amino acids should be maintained within normal limits. Ongoing monitoring of neurological and cardiac status, laboratory tests (renal, hepatic, haematological) and clinical responses in patients receiving carglumic acid is crucial to assess patient response.

4.5 Interactions with Other Medicines and Other Forms of Interactions

No specific clinical studies have been performed to assess possible interactions. Based on in vitro studies, carglumic acid is not an inducer of CYP1A1/2, 2B6 or 3A4/5 enzymes and is not an inhibitor of CYP1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1 or 3A4/5.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No formal clinical studies have been conducted to assess the effects of carglumic acid on fertility. There were no effects on fertility or reproductive performance in female rats at oral doses up to 2000 mg/kg/day (resulting in 28 times the clinical AUC). In a separate study, mating and fertility were unaffected in male rats at oral doses up to 1000 mg/kg/day (resulting in 14 times the estimated clinical AUC at the maximum recommended human dose, MRHD).
(Category B1)
There are no adequate and well controlled studies or available human data with carglumic acid in pregnant women. In embryofoetal development studies, no adverse effects were observed in pregnant rats and rabbits that received oral carglumic acid during organogenesis at doses up to 2000 mg/kg/day and 1000 mg/kg/day, respectively. These doses resulted in exposures (AUC) 28 and 2.4 times the estimated clinical AUC at the MRHD.
It is not known whether carglumic acid is excreted into human milk. Carglumic acid is excreted in the milk of lactating rats and an increase in mortality and impairment of bodyweight gain occurred in neonatal rats nursed by mothers receiving carglumic acid (see Section 4.3 Contraindications). Therefore, breastfeeding during the use of carglumic acid is contraindicated.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

NAGS deficiency.

The most common adverse events (occurring in ≥ 13% of patients), regardless of causality, are: infections, vomiting, abdominal pain, pyrexia, tonsillitis, anaemia, ear infection, diarrhoea, nasopharyngitis, and headache.
Table 1 summarises adverse events occurring in 2 or more patients treated with carglumic acid in the retrospective study.

Organic acidaemias.

The most common adverse events, regardless of causality, are anaemia, and thrombocytopenia.
Table 2 summarises adverse events occurring in 2 or more patients treated with carglumic acid in the retrospective study.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration 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 at www.tga.gov.au/reporting-problems.

4.9 Overdose

In one patient treated with carglumic acid, where the dose was increased up to 750 mg/kg/day, symptoms of intoxication occurred which can be characterised as a sympathomimetic reaction: tachycardia, profuse sweating, increased bronchial secretion, increased body temperature and restlessness. These symptoms resolved once the dose was reduced.
For information on the management of overdose, contact the Poison Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Carglumic acid is a structural analogue of N-acetylglutamate (NAG), which is the naturally occurring activator of carbamoyl phosphate synthetase 1 (CPS 1), the first enzyme of the urea cycle. N-acetylglutamate is the product of N-acetylglutamate synthase (NAGS). Where NAGS is defective, NAG synthesis is impaired and thus CPS 1 is not activated; consequently the urea cycle is not triggered. Carglumic acid has been shown in vitro to activate hepatic CPS 1. Although carglumic acid has a lower affinity for CPS than the naturally occurring NAG, in vivo it has showed more effective and longer lasting effect than NAG.
Other studies have been conducted in rats under different experimental conditions leading to increased ammonia availability (starvation, protein free or high protein diet). Carglumic acid was shown to decrease blood ammonia levels and increase urea levels in blood and urine, whereas the liver content of carbamoyl phosphate synthetase activators was significantly increased.

Clinical trials.

NAGS deficiency.

In patients with N-acetylglutamate synthase (NAGS) deficiency, carglumic acid has been shown to induce a rapid normalisation of plasma ammonia levels, usually within 24 hours. When the treatment was instituted before any permanent brain damage, patients exhibited normal growth and psychomotor development.
In a retrospective, noncomparative descriptive study, data was collected from NAGS deficiency patients treated with carglumic acid for the management of hyperammonaemia. Of the 23 patients reviewed, 18 were on long-term continuous therapy with carglumic acid. The mean baseline biochemistry results are summarised in Table 3.

Treatment with carglumic acid in NAGS comprised management of acute phase (initial 7 days), followed by long-term maintenance treatment. During acute treatment doses between 100-250 mg/kg/day administered 2-5 times per day were used. The dose was then reduced over time depending upon the clinical response, including laboratory monitoring.
Following treatment with carglumic acid in the acute phase, ammonaemia, glutaminaemia and citrullinaemia normalised quickly. Normal concentrations of these biomarkers were obtained 24-72 hours after the first dose of carglumic acid.
The demographic characteristics of the patient population are shown in Table 4.

Table 5 summarises the plasma ammonia levels at baseline, days 1 to 3 post-Carbaglu treatment, and long-term Carbaglu treatment for 13 evaluable patients.

The mean plasma ammonia level at baseline and the decline that is observed after treatment with Carbaglu in 13 evaluable patients with NAGS deficiency is illustrated in Figure 1.

The analysis of long-term treatment with carglumic acid showed continuous control of ammonaemia, glutaminaemia, a discontinuation of the daily protein intake restriction, improvement in the growth parameters, neurological status and psychomotor status.
There were no decompensation events during treatment with carglumic acid as long as the dose administered was adequate. Extremely low doses for age and weight exposed patients to sudden metabolic status decompensation.

Organic acidaemias.

In patients with organic acidaemia (neonates and non-neonates), the treatment with carglumic acid induced a quick decrease of ammonia plasma levels, reducing the risk of neurological complications.
In an observational study, based on retrospective analysis of the outcomes from treatment with carglumic acid, the reduction in plasma ammonia levels was assessed in patients during organic acidaemia (OA) decompensation episodes. In total, 57 patients were enrolled, with 41 included in the efficacy analysis following the treatment with carglumic acid during the OA decompensation episode. Seven patients reported two or more episodes during the treatment phase. No predefined dose of carglumic acid was stated, however the standard recommended initial dose of carglumic acid is 100-250 mg/kg/day, given twice or thrice daily, which was taken as reference for data analysis. The primary endpoint assigned for the study was the reduction in plasma ammonia levels following carglumic acid treatment.
From the 41 patients included in the efficacy analysis, 4 (9.8%) were confirmed as isovaleric acidaemia (IVA), 21 patients (51.2%) were confirmed as methylmalonic acidaemia (MMA), and 16 patients (39.0%) as confirmed propionic acidaemia (PA). The baseline age of the episodes in the efficacy population was a median of 9.0 days. At the initiation of the treatment with carglumic acid, 29 episodes (out of 48) occurred during the first 4 weeks after birth (neonates) and 19 episodes occurred beyond the neonatal period (non-neonates).
The baseline ammonaemia recorded was a mean of 350.7 micromol/L (range: 76.0 to 1633.0 micromol/L) in the efficacy population.
Treatment with carglumic acid in IA was aimed at resolution of acute decompensation episode. The majority of episodes were initially treated with a dose of carglumic acid 100-250 mg/kg/day. The duration of treatment ranged from 1 to 15 days with a mean of 5.5 days (5.2 days PA, 6.1 days MMA, 3.5 days IVA). The mean duration of treatment was 4.9 days in neonates and 5.3 days in non-neonates. A trend to decrease the dose from 1st to the last day (up to 15 days at the discretion of the treating physician) was seen as shown in Figure 2.

Following carglumic acid treatment, a significant biological response to the treatment with carglumic acid was observed, with the mean ammonaemia at primary endpoint of 58.5 micromol/L (range 15.0-58.0 micromol/L). The mean plasma ammonia concentrations decrease from baseline was -292.2 micromol/L with a reduction range from -24.0 to -1540.0 micromol/L.
When ammonia scavengers were administered concomitantly with carglumic acid, the respective plasma ammonia levels at the endpoint were:
with ammonia scavengers, a mean of 55.6 micromol/L;
and without ammonia scavengers a mean of 60.8 micromol/L.
The mean time to achieve the primary endpoint was 2.4 days (58.7 hours), with this time equivalent in the disease category groups. The median time to achieve the primary endpoint for the three OA was:
40.5 hours for the IVA episodes;
37.5 hours for the MMA episodes;
and 36.0 hours for the PA episodes.

5.2 Pharmacokinetic Properties

The pharmacokinetics of carglumic acid has been studied in healthy male volunteers using radiolabelled and unlabelled product.

Absorption.

After a single oral dose of 100 mg/kg bodyweight, approximately 30% of carglumic acid is estimated to be absorbed. At that dose level, in 12 volunteers given Carbaglu tablets, plasma concentration peaked at 2.6 microgram/mL (median; range 1.8-4.8) after 3 hours (median; range 2-4).
Absolute bioavailability of carglumic acid has not been determined.

Distribution.

The plasma elimination curve of carglumic acid is biphasic with a rapid phase over the first 12 hours after administration followed by a slow phase (terminal half-life up to 28 hours).
Protein binding has not been determined.

Metabolism.

A proportion of carglumic acid is metabolised, possibly by the intestinal flora. One possible end product of carglumic acid metabolism is carbon dioxide, which is eliminated through the lungs.

Excretion.

After a single oral dose of 100 mg/kg bodyweight, 9% of the dose is excreted unchanged in the urine and up to 60% in the faeces.
Plasma levels of carglumic acid were measured in patients of all age categories, from newborn infants to adolescents, treated with various daily doses (7-122 mg/kg/day). The ranges reported were consistent with those measured in healthy adults, including those from newborn infants. Regardless of the daily dose, plasma levels slowly declined over 15 hours to levels approximately 100 nanogram/mL.

5.3 Preclinical Safety Data

Genotoxicity.

Carglumic acid was negative in the Ames test, chromosomal aberration assay in human lymphocytes and in the in vivo micronucleus assay in rats.

Carcinogenicity.

Carcinogenicity studies have not been conducted.
