4.2 Posology and method of administration

Sugammadex should only be administered by, or under the supervision of an anaesthetist. The use of an appropriate neuromuscular monitoring technique is recommended to monitor the recovery of neuromuscular blockade. As is normal post-anaesthetic practice following neuromuscular blockade it is recommended to monitor the patient in the immediate post-operative period for untoward events including re-occurrence of blockade (see section 4.4). When certain medicinal products that may cause displacement interactions are administered parenterally within a period of 6 hours of sugammadex, the patient should be monitored for signs of re-occurrence of blockade (see section 4.4 and 4.5).

The recommended dose of sugammadex depends on the level of neuromuscular blockade to be reversed.

The recommended dose does not depend on the anaesthetic regimen.

Sugammadex can be used to reverse different levels of rocuronium or vecuronium induced neuromuscular blockade:

Adults

Routine reversal:

A dose of 4 mg/kg sugammadex is recommended if recovery has reached at least 1NON-BREAKING HYPHEN (8209)2 post-tetanic counts (PTC) following rocuronium or vecuronium induced blockade. Median time to recovery of the T4/T1 ratio to 0.9 is around 3 minutes (see section 5.1).

A dose of 2 mg/kg sugammadex is recommended, if spontaneous recovery has occurred up to at least the reappearance of T2 following rocuronium or vecuronium induced blockade. Median time to recovery of the T4/T1 ratio to 0.9 is around 2 minutes (see section 5.1).

Using the recommended doses for routine reversal will result in a slightly faster median time to recovery of the T4/T1 ratio to 0.9 of rocuronium when compared to vecuronium induced neuromuscular blockade (see section 5.1).

Immediate reversal of rocuronium-induced blockade:

If there is a clinical need for immediate reversal following administration of rocuronium a dose of 16 mg/kg sugammadex is recommended. When 16 mg/kg sugammadex is administered 3 minutes after a bolus dose of 1.2 mg/kg rocuronium bromide, a median time to recovery of the T4/T1 ratio to 0.9 of approximately 1.5 minutes can be expected (see section 5.1).

There is no data to recommend the use of sugammadex for immediate reversal following vecuronium induced blockade.

ReNON-BREAKING HYPHEN (8209)administration of sugammadex:

In the exceptional situation of reNON-BREAKING HYPHEN (8209)occurrence of blockade post-operatively (see section 4.4) after an initial dose of 2 mg/kg or 4 mg/kg sugammadex, a repeat dose of 4 mg/kg sugammadex is recommended. Following a second dose of sugammadex, the patient should be closely monitored to ascertain sustained return of neuromuscular function.

Re-administration of rocuronium or vecuronium after sugammadex:

A waiting time of 24 hours should be taken into account (see section 4.4).

Additional information on special population

Renal impairment:

For mild and moderate renal impairment (creatinine clearance GREATER-THAN OR EQUAL TO (8805) 30 and < 80 ml/min): the dose recommendations are the same as for adults.

The use of sugammadex in patients with severe renal impairment (including patients requiring dialysis (CrCl < 30 ml/min)) is not recommended (see section 4.4).

Elderly patients:

After administration of sugammadex at reappearance of T2 following a rocuronium induced blockade, the median time to recovery of the T4/T1 ratio to 0.9 in adults (18NON-BREAKING HYPHEN (8209)64 years) was 2.2 minutes, in elderly adults (65NON-BREAKING HYPHEN (8209)74 years) it was 2.6 minutes and in very elderly adults (75 years or more) it was 3.6 minutes. Even though the recovery times in elderly tend to be slower, the same dose recommendation as for adults should be followed (see section 4.4).

Obese patients:

In obese patients, the dose of sugammadex should be based on actual body weight. The same dose recommendations as for adults should be followed.

Hepatic impairment:

For mild to moderate hepatic impairment: as sugammadex is mainly excreted renally no dose adjustments are required.

Studies in patients with hepatic impairment have not been conducted and therefore patients with severe hepatic impairment should be treated with great caution (see section 4.4).

Paediatric population:

The data for the paediatric population are limited (one study only for reversal of rocuronium induced blockade at reappearance of T2).

Children and adolescents:

For routine reversal of rocuronium induced blockade at reappearance of T2 in children and adolescents (2NON-BREAKING HYPHEN (8209)17 years) 2 mg/kg sugammadex is recommended. Other routine reversal situations have not been investigated and are therefore not recommended until further data become available.

Immediate reversal in children and adolescents has not been investigated and is therefore not recommended until further data become available.

Bridion 100 mg/ml may be diluted to 10 mg/ml to increase the accuracy of dosing in the paediatric population (see section 6.6).

Term newborn infants and infants:

There is only limited experience with the use of sugammadex in infants (30 days to 2 years), and term newborn infants (less than 30 days) have not been studied. The use of sugammadex in term newborn infants and infants is therefore not recommended until further data become available.

Method of administration

Sugammadex should be administered intravenously as a single bolus injection. The bolus injection should be given rapidly, within 10 seconds directly into a vein or into an existing intravenous line (see section 6.6). Sugammadex has only been administered as a single bolus injection in clinical trials.

4.4 Special warnings and precautions for use

Monitoring respiratory function during recovery:

Ventilatory support is mandatory for patients until adequate spontaneous respiration is restored following reversal of neuromuscular block. Even if recovery from neuromuscular blockade is complete, other medicinal products used in the peri- and postoperative period could depress respiratory function and therefore ventilatory support might still be required.

Should neuromuscular blockade reoccur following extubation, adequate ventilation should be provided.

Re-occurrence of blockade:

In clinical trials re-occurrence of blockade was reported mainly when sub-optimal doses (in dose finding studies) were administered. In order to prevent reNON-BREAKING HYPHEN (8209)occurrence of neuromuscular blockade, the recommended doses for routine or immediate reversal (see section 4.2) should be used.

Effect on hemostasis:

In a study in volunteers doses of 4 mg/kg and 16 mg/kg of sugammadex prolonged by 17NON-BREAKING HYPHEN (8209)22% the activated partial thromboplastin time (aPTT) and prothrombin time (PT). In all cases, this slight prolongation was of short duration (< than 30 minutes). Based on the clinical data-base (n=1738) there was no clinically relevant effect of sugammadex alone or in combination with anticoagulants on the incidence of peri- or post-operative bleeding complications.

In in vitro experiments a pharmacodynamic interaction (aPTT and PT prolongation) was noted with vitamin K antagonists, unfractionated heparin, low molecular weight heparinoids, rivaroxaban and dabigatran. In patients receiving routine post-operative prophylactic anticoagulation this pharmacodynamic interaction is not clinically relevant. Caution should be exercised when considering the use of sugammadex in patients receiving therapeutic anticoagulation for a pre-existing or co-morbid condition.

An increased risk of bleeding can not be excluded in patients:

• with hereditary vitamin K dependent clotting factor deficiencies;

• with pre-existing coagulopathies;

• on coumarin derivates and at an INR above 3.5;

• using anticoagulants who receive a dose of 16 mg/kg sugammadex.

If there is a medical need to give sugammadex to these patients the anaesthesiologist needs to decide if the benefits outweigh the possible risk of bleeding complications taking into consideration the patients history of bleeding episodes and type of surgery scheduled. If sugammadex is administered to these patients monitoring of hemostasis and coagulation parameters is recommended.

Waiting times for reNON-BREAKING HYPHEN (8209)administration with neuromuscular blocking agents after reversal with sugammadex:

If reNON-BREAKING HYPHEN (8209)administration of rocuronium or vecuronium is required a waiting time of 24 hours is recommended.

If neuromuscular blockade is required before the recommended waiting time has passed, a nonsteroidal neuromuscular blocking agent should be used.

Renal impairment:

In patients with severe renal failure (creatinine clearance < 30 ml/min) the excretion of sugammadex or the sugammadex-rocuronium complex was delayed, however in these patients there were no signs of reNON-BREAKING HYPHEN (8209)occurrence of neuromuscular blockade. Data from a limited number of renally impaired patients requiring dialysis indicate an inconsistent decrease of plasma levels of sugammadex by haemodialysis. The use of sugammadex in patients with severe renal impairment is not recommended.

Interactions due to the lasting effect of rocuronium or vecuronium:

When medicinal products which potentiate neuromuscular blockade are used in the post-operative period special attention should be paid to the possibility of re-occurrence of blockade. Please refer to the package leaflet of rocuronium or vecuronium for a list of the specific medicinal products which potentiate neuromuscular blockade. In case reNON-BREAKING HYPHEN (8209)occurrence of blockade is observed, the patient may require mechanical ventilation and reNON-BREAKING HYPHEN (8209)administration of sugammadex (see section 4.2).

Potential interactions:

• Capturing interactions:

Due to the administration of sugammadex, certain medicinal products could become less effective due to a lowering of the (free) plasma concentrations (see section 4.5, hormonal contraceptives).

If such a situation is observed, the clinician is advised to consider the re-administration of the medicinal product, the administration of a therapeutically equivalent medicinal product (preferably from a different chemical class) and/or non-pharmacological interventions as appropriate.

• Displacement interactions:

Due to the administration of certain medicinal products after sugammadex, theoretically rocuronium or vecuronium could be displaced from sugammadex. As a result re-occurrence of blockade might be observed. In this situation the patient must be ventilated. Administration of the medicinal product which caused displacement should be stopped in case of an infusion. In situations when potential displacement interactions can be anticipated, patients should be carefully monitored for signs of re-occurrence of blockade (approximately up to 15 minutes) after parenteral administration of another medicinal product occurring within a period of 6 hours after sugammadex administration. Displacement interactions are at present only expected for a few drugs substances (toremifene and fusidic acid, see section 4.5).

Light anaesthesia:

When neuromuscular blockade was reversed intentionally in the middle of anaesthesia in clinical trials, signs of light anaesthesia were noted occasionally (movement, coughing, grimacing and suckling of the tracheal tube).

If neuromuscular blockade is reversed, while anaesthesia is continued, additional doses of anaesthetic and/or opioid should be given as clinically indicated.

Hepatic impairment:

Sugammadex is not metabolised nor excreted by the liver; therefore dedicated studies in patients with hepatic impairment have not been conducted. Patients with severe hepatic impairment should be treated with great caution.

Use in Intensive Care Unit (ICU):

Sugammadex has not been investigated in patients receiving rocuronium or vecuronium in the ICU setting.

Use for reversal of neuromuscular blocking agents other than rocuronium or vecuronium:

Sugammadex should not be used to reverse block induced by nonsteroidal neuromuscular blocking agents such as succinylcholine or benzylisoquinolinium compounds.

Sugammadex should not be used for reversal of neuromuscular blockade induced by steroidal neuromuscular blocking agents other than rocuronium or vecuronium, since there are no efficacy and safety data for these situations. Limited data are available for reversal of pancuronium induced blockade, but it is advised not to use sugammadex in this situation.

Delayed recovery:

Conditions associated with prolonged circulation time such as cardiovascular disease, old age (see section 4.2 for the time to recovery in elderly), or oedematous state may be associated with longer recovery times.

Allergic reactions:

Clinicians should be prepared for the possibility of allergic reactions and take the necessary precautions (see section 4.8).

Patients on a controlled sodium diet:

Each ml solution contains 9.7 mg sodium. A dose of 23 mg sodium is considered essentially 'sodium-free'. If more than 2.4 ml solution needs to be administered, this should be taken into consideration by patients on a controlled sodium diet.

QTc-interval prolongation:

Two thorough QTc trials (N=146), both in conscious volunteers, demonstrated that sugammadex alone or in combination with rocuronium or vecuronium is not associated with QTc interval prolongation. The one-sided 95% upper confidence limits for the QTc difference to placebo were well below the 10 ms margin for each of the 12NON-BREAKING HYPHEN (8209)13 evaluated timepoints in both studies.

In the clinical program, a few cases of QTc prolongation were reported (QTc> 500 msec or QTc increases> 60 msec) in clinical trials in which patients received sugammadex in combination with sevoflurane or propofol. During anaesthesia several medicinal products with the potential to prolong QTc (e.g. sevoflurane) are administered. The routine precautions for treating arrhythmia should be taken into consideration.

4.5 Interaction with other medicinal products and other forms of interaction

The information in this section is based on binding affinity between sugammadex and other medicinal products, non-clinical experiments, clinical studies and simulations using a model taking into account the pharmacodynamic effect of neuromuscular blocking agents and the pharmacokinetic interaction between neuromuscular blocking agents and sugammadex. Based on these data, no clinically significant pharmacodynamic interaction with other medicinal products is expected, with exception of the following:

For toremifene and fusidic acid displacement interactions could not be excluded (no clinically relevant capturing interactions are expected).

For hormonal contraceptives a clinically relevant capturing interaction could not be excluded (no displacement interactions are expected).

Interactions potentially affecting the efficacy of sugammadex (see also section 4.4):

Toremifene:

For toremifene, which has a relatively high affinity constant and relatively high plasma concentrations, some displacement of vecuronium or rocuronium from the complex with sugammadex could occur. The recovery of the T4/T1 ratio to 0.9 could therefore be delayed in patients who have received toremifene on the same day of the operation.

Intravenous administration of fusidic acid:

The use of fusidic acid in the pre-operative phase may give some delay in the recovery of the T4/T1 ratio to 0.9. No re-occurrence of neuromuscular blockade is expected in the post-operative phase, since the infusion rate of fucidic acid is over a period of several hours and the blood levels are cumulative over 2-3 days. For reNON-BREAKING HYPHEN (8209)administration of sugammadex see section 4.2.

Interactions potentially affecting the efficacy of other medicinal products (see also section 4.4):

Hormonal contraceptives:

The interaction between 4 mg/kg sugammadex and a progestogen was predicted to lead to a decrease in progestogen exposure (34% of AUC) similar to the decrease seen when a missed daily dose of an oral contraceptive is taken 12 hours too late, which might lead to a reduction in effectiveness. For estrogens, the effect is expected to be lower. Therefore the administration of a bolus dose of sugammadex is considered to be equivalent to one missed daily dose of oral contraceptive steroids (either combined or progestogen only). If sugammadex is administered at the same day as an oral contraceptive is taken reference is made to missed dose advice in the package leaflet of the oral contraceptive. In the case of non-oral hormonal contraceptives, the patient must use an additional non hormonal contraceptive method for the next 7 days and refer to the advice in the package leaflet of the product.

Interference with laboratory tests:

In general sugammadex does not interfere with laboratory tests, with the possible exception of the serum progesterone assay. Interference with this test is observed at sugammadex plasma concentrations of 100 μg/ml (peak plasma level following 8 mg/kg bolus injection).

In a study in volunteers doses of 4 mg/kg and 16 mg/kg of sugammadex prolonged by 17NON-BREAKING HYPHEN (8209)22% the activated partial thromboplastin time (aPTT) and prothrombin time (PT). In all cases, this slight prolongation was of short duration (< than 30 minutes).

In in vitro experiments a pharmacodynamic interaction (aPTT and PT prolongation) was noted with vitamin K antagonists, unfractionated heparin, low molecular weight heparinoids, rivaroxaban and dabigatran (see section 4.4).

Paediatric population

No formal interaction studies have been performed. The above mentioned interactions for adults and the warnings in section 4.4 should also be taken into account for the paediatric population.

4.6 Pregnancy and lactation

For sugammadex no clinical data on exposed pregnancies are available.

Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonic/foetal development, parturition or postnatal development.

Caution should be exercised when administering sugammadex to pregnant women.

It is unknown whether sugammadex is excreted in human breast milk. Animal studies have shown excretion of sugammadex in breast milk. Oral absorption of cyclodextrins in general is low and no effects on the suckling child is anticipated following a single dose to the breast-feeding woman.

Sugammadex can be used during breast-feeding.

4.8 Undesirable effects

The safety of sugammadex has been evaluated based on an integrated safety database of approximately 1700 patients and 120 volunteers. The most commonly reported adverse reaction dysgeusia (metal or bitter taste) was mainly seen after doses of 32 mg/kg sugammadex or higher. In a few individuals allergic-like reactions (i.e. flushing, erythematous rash) following sugammadex were reported of which one was a confirmed mild allergic reaction.

Awareness:

In sugammadex treated subjects a few cases of awareness were reported. The relation to sugammadex is uncertain.

Re-occurrence of blockade:

In the data-base of pooled phase INON-BREAKING HYPHEN (8209)III studies with a placebo group, the incidence of re-occurrence of blockade as measured with neuromuscular monitoring was 2% after sugammadex and 0% in the placebo group. Virtually all of these cases were from dose-finding studies in which a sub-optimal dose (less than 2 mg/kg) was administered (see section 4.4).

Additional information on special populations

Pulmonary patients:

In one clinical trial in patients with a history of pulmonary complications bronchospasm was reported as a possibly related adverse event in two patients and a causal relationship could not be fully excluded. As with all patients with a history of pulmonary complications the physician should be aware of the possible occurrence of bronchospasm.

Paediatric population

A limited database suggests that the safety profile of sugammadex (up to 4 mg/kg) in paediatric patients was similar to that in adults.

4.9 Overdose

In clinical studies, 1 case of an accidental overdose with 40 mg/kg was reported without any significant undesirable effects. In a human tolerance study sugammadex was administered in doses up to 96 mg/kg. No dose related adverse events nor serious adverse events were reported.

5. PHARMACOLOGICAL PROPERTIES

Go to top of the page
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: all other therapeutic products, ATC code: V03AB35

Mechanism of action:

Sugammadex is a modified gamma cyclodextrin which is a Selective Relaxant Binding Agent. It forms a complex with the neuromuscular blocking agents rocuronium or vecuronium in plasma and thereby reduces the amount of neuromuscular blocking agent available to bind to nicotinic receptors in the neuromuscular junction. This results in the reversal of neuromuscular blockade induced by rocuronium or vecuronium.

Pharmacodynamic effects:

Sugammadex has been administered in doses ranging from 0.5 mg/kg to 16 mg/kg in dose response studies of rocuronium induced blockade (0.6, 0.9, 1.0 and 1.2 mg/kg rocuronium bromide with and without maintenance doses) and vecuronium induced blockade (0.1 mg/kg vecuronium bromide with or without maintenance doses) at different time points/depths of blockade. In these studies a clear dose-response relationship was observed.

Clinical efficacy and safety:

Sugammadex can be administered at several time points after administration of rocuronium or vecuronium bromide:

Routine reversal – deep neuromuscular blockade:

In a pivotal study patients were randomly assigned to the rocuronium or vecuronium group. After the last dose of rocuronium or vecuronium, at 1NON-BREAKING HYPHEN (8209)2 PTCs, 4 mg/kg sugammadex or 70 mcg/kg neostigmine was administered in a randomised order. The time from start of administration of sugammadex or neostigmine to recovery of the T4/T1 ratio to 0.9 was:

5.2 Pharmacokinetic properties

The sugammadex pharmacokinetic parameters were calculated from the total sum of non-complex-bound and complex-bound concentrations of sugammadex. Pharmacokinetic parameters as clearance and volume of distribution are assumed to be the same for non-complex-bound and complex-bound sugammadex in anaesthetised subjects.

Distribution:

The steady-state volume of distribution of sugammadex is approximately 11 to 14 litres. Neither sugammadex nor the complex of sugammadex and rocuronium bind to plasma proteins or erythrocytes, as was shown in vitro using male human plasma and whole blood. Sugammadex exhibits linear kinetics in the dosage range of 1 to 16 mg/kg when administered as an IV bolus dose.

Metabolism:

In preclinical and clinical studies no metabolites of sugammadex have been observed and only renal excretion of the unchanged product was observed as the route of elimination.

Elimination:

The elimination half-life (t½) of sugammadex in adults is 1.8 hours and plasma clearance is estimated to be 88 ml/min. A mass balance study demonstrated that> 90% of the dose was excreted within 24 hours. 96% of the dose was excreted in urine, of which at least 95% could be attributed to unchanged sugammadex. Excretion via faeces or expired air was less than 0.02% of the dose. Administration of sugammadex to healthy volunteers resulted in increased renal elimination of rocuronium in complex.

Special populations:

Elderly and renal impairment:

Paediatrics:

Pharmacokinetics in paediatric patients (n=51) with ages ranging from 0 to 17 years were evaluated using population pharmacokinetic (PK) analysis. In patients under age 18, volume of distribution and clearance increase with increasing age. Variability of plasma concentrations of sugammadex in paediatric patients is comparable to the variability in adult patients. The pharmacokinetic (PK) parameters of two typical paediatric patients are summarised below:

5.3 Preclinical safety data

Preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity potential, and toxicity to reproduction, local tolerance or compatibility with blood.

Sugammadex is rapidly cleared from most organs; however some retention of compound occurs in bone and teeth in the rat. The most likely component involved in the reversible binding is hydroxy apatite, the inorganic matrix in these tissues. Preclinical studies in young adult and mature rats have shown that this retention does not adversely affect tooth colour or bone quality, structure, turnover and development. In juvenile rats whitish discoloration was observed in the incisors and disturbance of enamel formation was observed upon repeated dosing, however at exposure levels of 48NON-BREAKING HYPHEN (8209)480 times the clinical exposure at 4 mg/kg.
