For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Solution for injection in a vial.



Solution for injection in a cartridge.



Solution for injection in pre-filled pen, OptiSet.



Clear, colourless, aqueous solution.



4. Clinical Particulars



4.1 Therapeutic Indications



Treatment of adults, adolescents and children, 6 years or older with diabetes mellitus, where treatment with insulin is required.



4.2 Posology And Method Of Administration



The potency of this preparation is stated in units. These units are exclusive to Apidra and are not the same as IU or the units used to express the potency of other insulin analogues (see section 5.1).



Apidra should be used in regimens that include an intermediate or long acting insulin or basal insulin analogue and can be used with oral hypoglycaemic agents.



The dose of Apidra should be individually adjusted.



Special populations



Renal impairment



The pharmacokinetic properties of insulin glulisine are generally maintained in patients with renal impairment. However, insulin requirements may be reduced in the presence of renal impairment (see section 5.2).



Hepatic impairment



The pharmacokinetic properties of insulin glulisine have not been investigated in patients with decreased liver function. In patients with hepatic impairment, insulin requirements may be diminished due to reduced capacity for gluconeogenesis and reduced insulin metabolism.



Elderly



Limited pharmacokinetic data are available in elderly patients with diabetes mellitus. Deterioration of renal function may lead to a decrease in insulin requirements.



Paediatric population



There is insufficient clinical information on the use of Apidra in children younger than the age of 6 years.



Administration



Vials: Intravenous use



Apidra can be administered intravenously. This should be carried out by health care professionals.



Apidra must not be mixed with glucose or Ringer's solution or with any other insulin.



Vials, cartridges and OptiSet: Subcutaneous use



Apidra should be given by subcutaneous injection shortly (0-15 min) before or soon after meals or by continuous subcutaneous pump infusion.



Apidra should be administered subcutaneously in the abdominal wall, thigh or deltoid or by continuous infusion in the abdominal wall. Injection sites and infusion sites within an injection area (abdomen, thigh or deltoid) should be rotated from one injection to the next. The rate of absorption, and consequently the onset and duration of action, may be affected by the injection site, exercise and other variables. Subcutaneous injection in the abdominal wall ensures a slightly faster absorption than other injection sites (see section 5.2).



Care should be taken to ensure that a blood vessel has not been entered. After injection, the site of injection should not be massaged. Patients must be educated to use proper injection techniques.



When used with a subcutaneous insulin infusion pump, Apidra must not be mixed with diluents or any other insulin.



Mixing with insulins



When administered as a subcutaneous injection, Apidra must not be mixed with other medicinal products except NPH human insulin.



Before using OptiSet, the Instructions for use included in the Package leaflet must be read carefully (see section 6.6). For further details on handling all preparations, see section 6.6.



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



Hypoglycaemia.



4.4 Special Warnings And Precautions For Use



Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type (regular, neutral protamine Hagedorn [NPH], lente, long-acting, etc.), origin (animal, human, human insulin analogue) and/or method of manufacture may result in the need for a change in dose. Concomitant oral antidiabetic treatment may need to be adjusted.



The use of inadequate doses or discontinuation of treatment, especially in insulin-dependent diabetic, may lead to hyperglycaemia and diabetic ketoacidosis; conditions which are potentially lethal.



The time of occurrence of hypoglycaemia depends on the action profile of the insulins used and may, therefore, change when the treatment regimen is changed.



Conditions which may make the early warning symptoms of hypoglycaemia different or less pronounced include long duration of diabetes, intensified insulin therapy, diabetic nerve disease, medicinal products such as beta blockers or after transfer from animal-source insulin to human insulin.



Adjustment of dose may be also necessary if patients undertake increased physical activity or change their usual meal plan. Exercise taken immediately after a meal may increase the risk of hypoglycaemia.



When compared with soluble human insulin, if hypoglycaemia occurs after an injection with rapid acting analogues, it may occur earlier.



Uncorrected hypoglycaemic or hyperglycaemic reactions can cause loss of consciousness, coma, or death.



Insulin requirements may be altered during illness or emotional disturbances. .



Medication errors have been reported in which other insulins, particularly long-acting insulins, have been accidentally administered instead of insulin glulisine. Insulin label must always be checked before each injection to avoid medication errors between insulin glulisine and other insulins.



This medicinal product contains less than 1 mmol (23 mg) sodium per dose, i.e. it is essentially 'sodium-free'.



Apidra contains metacresol, which may cause allergic reactions.



Combination of Apidra with pioglitazone



Cases of cardiac failure have been reported when pioglitazone was used in combination with insulin, especially in patients with risk factors for development of cardiac heart failure. This should be kept in mind if treatment with the combination of pioglitazone and Apidra is considered. If the combination is used, patients should be observed for signs and symptoms of heart failure, weight gain and oedema. Pioglitazone should be discontinued if any deterioration in cardiac symptoms occurs.



Pens to be used with Apidra cartridges



The Apidra cartridges should only be used with the following pens: OptiPen, ClikSTAR and Autopen 24 and should not be used with any other reusable pen as the dosing accuracy has only been established with the listed pens.



Handling of the OptiSet pen



Before using OptiSet, the Instructions for use included in the Package leaflet must be read carefully.



OptiSet has to be used as recommended in these Instructions for use (see section 6.6).



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Studies on pharmacokinetic interactions have not been performed. Based on empirical knowledge from similar medicinal products, clinically relevant pharmacokinetic interactions are unlikely to occur.



A number of substances affect glucose metabolism and may require dose adjustment of insulin glulisine and particularly close monitoring.



Substances that may enhance the blood-glucose-lowering activity and increase susceptibility to hypoglycaemia include oral antidiabetic agents, angiotensin converting enzyme (ACE) inhibitors, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors (MAOIs), pentoxifylline, propoxyphene, salicylates and sulfonamide antibiotics.



Substances that may reduce the blood-glucose-lowering activity include corticosteroids, danazol, diazoxide, diuretics, glucagon, isoniazid, phenothiazine derivatives, somatropin, sympathomimetic agents (e.g. epinephrine [adrenaline], salbutamol, terbutaline), thyroid hormones, estrogens, progestins (e.g. in oral contraceptives), protease inhibitors and atypical antipsychotic medicinal products (e.g. olanzapine and clozapine).



Beta-blockers, clonidine, lithium salts or alcohol may either potentiate or weaken the blood-glucose-lowering activity of insulin. Pentamidine may cause hypoglycaemia, which may sometimes be followed by hyperglycaemia.



In addition, under the influence of sympatholytic medicinal products such as beta-blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter-regulation may be reduced or absent.



4.6 Pregnancy And Lactation



Pregnancy



There are no adequate data on the use of insulin glulisine in pregnant women.



Animal reproduction studies have not revealed any differences between insulin glulisine and human insulin regarding pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3).



Caution should be exercised when prescribing to pregnant women. Careful monitoring of glucose control is essential.



It is essential for patients with pre-existing or gestational diabetes to maintain good metabolic control throughout pregnancy. Insulin requirements may decrease during the first trimester and generally increase during the second and third trimesters. Immediately after delivery, insulin requirements decline rapidly.



Lactation



It is unknown whether insulin glulisine is excreted in human milk, but in general insulin does not pass into breast milk and is not absorbed after oral administration.



Breast-feeding mothers may require adjustments in insulin dose and diet.



4.7 Effects On Ability To Drive And Use Machines



The patient's ability to concentrate and react may be impaired as a result of hypoglycaemia or hyperglycaemia or, for example, as a result of visual impairment. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating machinery).



Patients should be advised to take precautions to avoid hypoglycaemia whilst driving. This is particularly important in those who have reduced or absent awareness of the warning symptoms of hypoglycaemia or have frequent episodes of hypoglycaemia. The advisability of driving should be considered in these circumstances.



4.8 Undesirable Effects



Hypoglycaemia, the most frequent undesirable effect of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement.



The following related adverse reactions from clinical studies were listed below by system organ class and in order of decreasing incidence (very common:



Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

Metabolism and nutrition disorders



Symptoms of hypoglycaemia usually occur suddenly. They may include cold sweats, cool pale skin, fatigue, nervousness or tremor, anxiousness, unusual tiredness or weakness, confusion, difficulty in concentration, drowsiness, excessive hunger, vision changes, headache, nausea and palpitation.



Hypoglycaemia can become severe and may lead to unconsciousness and/or convulsions and may result in temporary or permanent impairment of brain function or even death.



Skin and subcutaneous tissue disorders



Local hypersensitivity reactions (redness, swelling and itching at the injection site) may occur during treatment with insulin. These reactions are usually transitory and normally they disappear during continued treatment.



Lipodystrophy may occur at the injection site as a consequence of failure to rotate injection sites within an area.



General disorders and administration site conditions



Systemic hypersensitivity reactions may include urticaria, chest tightness, dyspnea, allergic dermatitis and pruritus. Severe cases of generalized allergy, including anaphylactic reaction, may be life-threatening.



4.9 Overdose



Hypoglycaemia may occur as a result of an excess of insulin activity relative to food intake and energy expenditure.



There are no specific data available concerning overdoses with insulin glulisine. However, hypoglycaemia may develop over sequential stages:



Mild hypoglycaemic episodes can be treated by oral administration of glucose or sugary products. It is therefore recommended that the diabetic patient constantly carries some sugar lumps, sweets, biscuits or sugary fruit juice.



Severe hypoglycaemic episodes, where the patient has become unconscious, can be treated by glucagon (0.5 mg to 1 mg) given intramuscularly or subcutaneously by a person who has received appropriate instruction, or by glucose given intravenously by a healthcare professional. Glucose must also be given intravenously, if the patient does not respond to glucagon within 10 to 15 minutes.



Upon regaining consciousness, administration of oral carbohydrate is recommended for the patient in order to prevent relapse.



After an injection of glucagon, the patient should be monitored in a hospital in order to find the reason for this severe hypoglycaemia and prevent other similar episodes.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Insulins and analogues for injection, fast-acting. ATC code: A10AB06



Insulin glulisine is a recombinant human insulin analogue that is equipotent to regular human insulin.



Insulin glulisine has a more rapid onset of action and a shorter duration of action than regular human insulin.



The primary activity of insulins and insulin analogues, including insulin glulisine, is regulation of glucose metabolism. Insulins lower blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis and enhances protein synthesis.



Studies in healthy volunteers and patients with diabetes demonstrated that insulin glulisine is more rapid in onset of action and of shorter duration of action than regular human insulin when given subcutaneously. When insulin glulisine is injected subcutaneously, the glucose lowering activity will begin within 10 – 20 minutes. After intravenous administration, a faster onset and shorter duration of action, as well as a greater peak response were observed as compared with subcutaneous administration. The glucose-lowering activities of insulin glulisine and regular human insulin are equipotent when administered by intravenous route. One unit of insulin glulisine has the same glucose - lowering activity as one unit of regular human insulin.



Dose proportionality



In a study with 18 male subjects with diabetes mellitus type 1 aged 21 to 50 years, insulin glulisine displayed dose-proportional glucose lowering effect in the therapeutic relevant dose range 0.075 to 0.15 Units/kg, and less than proportional increase in glucose lowering effect with 0.3 Units/kg or higher, like human insulin.



Insulin glulisine takes effect about twice as fast as regular human insulin and completes the glucose lowering effect about 2 hours earlier than regular human insulin.



A phase I study in patients with type 1 diabetes mellitus assessed the glucose lowering profiles of insulin glulisine and regular human insulin administered subcutaneously at a dose of 0.15 Units/kg, at different times in relation to a 15-minute standard meal. Data indicated that insulin glulisine administered 2 minutes before the meal gives similar postprandial glycemic control compared to regular human insulin given 30 minutes before the meal. When given 2 minutes prior to meal, insulin glulisine provided better postprandial control than regular human insulin given 2 minutes before the meal. Insulin glulisine administered 15 minutes after starting the meal gives similar glycemic control as regular human insulin given 2 minutes before the meal (see figure 1).









Figure 1: Average glucose

Obesity



A phase I study carried out with insulin glulisine, lispro and regular human insulin in an obese population has demonstrated that insulin glulisine maintains its rapid-acting properties. In this study, the time to 20 % of total AUC and the AUC (0-2h) representing the early glucose lowering activity were respectively of 114 minutes and 427 mg/kg for insulin glulisine, 121 minutes and 354 mg/kg for lispro, 150 minutes and 197 mg/kg for regular human insulin (see figure 2).





Figure 2: Glucose infusion rates (GIR) after subcutaneous injection of 0.3 Units/kg of insulin glulisine (GLULISINE) or insulin lispro (LISPRO) or regular human insulin (REGULAR) in an obese population.



Another phase I study with insulin glulisine and insulin lispro in a non-diabetic population in 80 subjects with a wide range of body mass indices (18-46 kg/m²) has demonstrated that rapid action is generally maintained across a wide range of body mass indices (BMI), while total glucose lowering effect decreases with increasing obesity.



The average total GIR AUC between 0–1 hour was 102±75 mg/kg and 158±100 mg/kg with 0.2 and 0.4 Units/kg insulin glulisine, respectively, and was 83.1±72.8 mg/kg and 112.3±70.8 mg/kg with 0.2 and 0.4 Units/kg insulin lispro respectively.



A phase I study in 18 obese patients with type 2 diabetes mellitus (BMI between 35 and 40 kg/m2) with insulin glulisine and insulin lispro [90% CI:0.81, 0.95 (p=<0.01)]has shown that insulin glulisine effectively controls diurnal post-prandial blood glucose excursions.



Clinical studies



Type 1 diabetes mellitus-Adults



In a 26-week phase III clinical study comparing insulin glulisine with insulin lispro both injected subcutaneously shortly (0-15 minutes) before a meal in patients with type 1 diabetes mellitus using insulin glargine as basal insulin, insulin glulisine was comparable to insulin lispro for glycemic control as reflected by changes in glycated haemoglobin (expressed as HbA1c equivalent) from baseline to endpoint. Comparable self-monitored blood glucose values were observed. No increase in the basal insulin dose was needed with insulin glulisine, in contrast to insulin lispro.



A 12-week phase III clinical study performed in patients with type 1 diabetes mellitus receiving insulin glargine as basal therapy indicate that the immediate postmeal administration of insulin glulisine provides efficacy that was comparable to immediate premeal insulin glulisine (0-15 minutes) or regular insulin (30-45 minutes).



In the per protocol population there was a significantly larger observed reduction in GHb in the premeal glulisine group compared with the regular insulin group.



Type 1 diabetes mellitus-Paediatric



A 26-week phase III clinical study compared insulin glulisine with insulin lispro both injected subcutaneously shortly (0-15 minutes) before a meal in children (4-5 years: n=9; 6-7 years: n=32 and 8-11 years: n=149) and adolescents (12-17 years: n=382) with type 1 diabetes mellitus using insulin glargine or NPH as basal insulin. Insulin glulisine was comparable to insulin lispro for glycaemic control as reflected by changes in glycated haemoglobin (GHb expressed as HbA1c equivalent) from baseline to endpoint and by self-monitored blood glucose values.



There is insufficient clinical information on the use of Apidra in children younger than the age of 6 years.



Type 2 diabetes mellitus-Adults



A 26-week phase III clinical study followed by a 26-week extension safety study was conducted to compare insulin glulisine (0-15 minutes before a meal) with regular human insulin (30-45 minutes before a meal) injected subcutaneously in patients with type 2 diabetes mellitus also using NPH insulin as basal insulin. The average body mass index (BMI) of patients was 34.55 kg/ m2. Insulin glulisine was shown to be comparable to regular human insulin with regard to glycated haemoglobin (expressed as HbA1c equivalent) changes from baseline to the 6-month endpoint (-0.46% for insulin glulisine and -0.30% for regular human insulin, p=0.0029) and from baseline to the 12-month endpoint (-0.23% for insulin glulisine and -0.13% for regular human insulin, difference not significant). In this study, the majority of patients (79%) mixed their short acting insulin with NPH insulin immediately prior to injection and 58% of subjects used oral hypoglycemic agents at randomization and were instructed to continue to use them at the same dose.



Race and gender



In controlled clinical trials in adults, insulin glulisine did not show differences in safety and efficacy in subgroup analyses based on race and gender.



5.2 Pharmacokinetic Properties



In insulin glulisine the replacement of the human insulin amino acid asparagine in position B3 by lysine and the lysine in position B29 by glutamic acid favors more rapid absorption.



In a study with 18 male subjects with diabetes mellitus type 1, aged 21 to 50 years, insulin glulisine displays dose-proportionality for early, maximum and total exposure in the dose range 0.075 to 0.4 Units/kg.



Absorption and bioavailability



Pharmacokinetic profiles in healthy volunteers and diabetes patients (type 1 or 2) demonstrated that absorption of insulin glulisine was about twice as fast with a peak concentration approximately twice as high as compared to regular human insulin.



In a study in patients with type 1 diabetes mellitus after subcutaneous administration of 0.15 Units/kg, for insulin glulisine the Tmax was 55 minutes and Cmax was 82 ± 1.3 μUnits/ml compared to a Tmax of 82 minutes and a Cmax of 46 ± 1.3 μUnits/ml for regular human insulin. The mean residence time of insulin glulisine was shorter (98 min) than for regular human insulin (161 min) (see figure 3).





Figure 3: Pharmacokinetic profile of insulin glulisine and regular human insulin in type 1 diabetes mellitus patients after a dose of 0.15 Units/kg.



In a study in patients with type 2 diabetes mellitus after subcutaneous administration of 0.2 Units/kg insulin glulisine, the Cmax was 91 μUnits/ml with the interquartile range from 78 to 104 μUnits/ml.



When insulin glulisine was injected subcutaneously into abdomen, deltoid and thigh, the concentration-time profiles were similar with a slightly faster absorption when administered in the abdomen compared to the thigh. Absorption from deltoid sites was in-between (see section 4.2). The absolute bioavailability (70%) of insulin glulisine was similar between injection sites and of low intra-subject variability (11%CV). Intravenous bolus administration of insulin glulisine resulted in a higher systemic exposure when compared to subcutaneous injection, with a Cmax approximately 40-fold higher.



Obesity



Another phase I study with insulin glulisine and insulin lispro in a non-diabetic population in 80 subjects with a wide range of body mass indices (18-46 kg/m²) has demonstrated that rapid absorption and total exposure is generally maintained across a wide range of body mass indices.



The time to 10% of total INS exposure was reached earlier by approximately 5–6 min with insulin glulisine.



Distribution and elimination



The distribution and elimination of insulin glulisine and regular human insulin after intravenous administration is similar with volumes of distribution of 13 l and 22 l and half-lives of 13 and 18 minutes, respectively.



After subcutaneous administration, insulin glulisine is eliminated more rapidly than regular human insulin with an apparent half-life of 42 minutes compared to 86 minutes. In an across study analysis of insulin glulisine in either healthy subjects or subjects with type 1 or type 2 diabetes mellitus the apparent half-life ranged from 37 to 75 minutes (interquartile range).



Insulin glulisine shows low plasma protein binding, similar to human insulin.



Special populations

In a clinical study performed in non-diabetic subjects covering a wide range of renal function (CrCl> 80 ml/min, 30-50 ml/min, < 30 ml/min), the rapid-acting properties of insulin glulisine were generally maintained. However, insulin requirements may be reduced in the presence of renal impairment.



Hepatic impairment



The pharmacokinetic properties have not been investigated in patients with impaired liver function.



Elderly



Very limited pharmacokinetic data are available for elderly patients with diabetes mellitus.



Children and adolescents



The pharmacokinetic and pharmacodynamic properties of insulin glulisine were investigated in children (7-11 years) and adolescents (12-16 years) with type 1 diabetes mellitus. Insulin glulisine was rapidly absorbed in both age groups, with similar Tmax and Cmax as in adults (see section 4.2).



Administered immediately before a test meal, insulin glulisine provided better postprandial control than regular human insulin, as in adults (see section 5.1). The glucose excursion (AUC 0-6h) was 641 mg.h.dl-1 for insulin glulisine and 801 mg.h.dl-1 for regular human insulin.



5.3 Preclinical Safety Data



Non-clinical data did not reveal toxicity findings others than those linked to the blood glucose lowering pharmacodynamic activity (hypoglycemia), different from regular human insulin or of clinical relevance for humans.

6.6 Special Precautions For Disposal And Other Handling



Insulin label must always be checked before each injection to avoid medication errors between insulin glulisine and other insulins (see section 4.4)



Mixing with insulins



When mixed with NPH human insulin, Apidra should be drawn into the syringe first. Injection should be given immediately after mixing as no data are available regarding the mixtures made up a significant time before injection.



Vials: Intravenous use



Apidra should be used at a concentration of 1 Unit/ml insulin glulisine in infusion systems with sodium chloride 9 mg/ml (0.9%) solution for infusion with or without 40 mmol/l potassium chloride using coextruded polyolefin/polyamide plastic infusion bags with a dedicated infusion line. Insulin glulisine for intravenous use at a concentration of 1 Unit/ml is stable at room temperature for 48 hours.



After dilution for intravenous use, the solution should be inspected visually for particulate matter prior to administration. It must only be used if the solution is clear and colourless, not when cloudy or with visible particles.



Apidra was found to be incompatible with Glucose 5% solution and Ringer's solution and, therefore, must not be used with these solution fluids. The use of other solutions has not been studied.



Vials: Subcutaneous use



Apidra vials are for use with insulin syringes with the corresponding unit scale and for use with an insulin pump system (see section 4.2).



Inspect the vial before use. It must only be used if the solution is clear, colourless, with no solid particles visible. Since Apidra is a solution, it does not require resuspension before use.



Continuous subcutaneous infusion pump



Apidra may be used for Continuous Subcutaneous Insulin Infusion (CSII) in pump systems suitable for insulin infusion with the appropriate catheters and reservoirs.



Patients using CSII should be comprehensively instructed on the use of the pump system. The infusion set and reservoir should be changed every 48 hours using aseptic technique.



Patients administering Apidra by CSII must have alternative insulin available in case of pump system failure.



Cartridges



The Apidra cartridges are to be used only in conjunction with OptiPen, ClikSTAR or Autopen 24 (see section 4.4).



The pen should be used as recommended in the information provided by the device manufacturer.



The manufacturer's instructions for using the pen must be followed carefully for loading the cartridge, attaching the needle, and administering the insulin injection. Inspect the cartridge before use. It must only be used if the solution is clear, colourless, with no solid particles visible. Before insertion of the cartridge into the reusable pen, the cartridge must be stored at room temperature for 1 to 2 hours. Air bubbles must be removed from the cartridge before injection (see instruction for using pen). Empty cartridges must not be refilled.



If the pen malfunctions (see instructions for using the pen), the solution may be drawn from the cartridge into a syringe (suitable for an insulin with 100 Units/ml) and injected. If the insulin pen is damaged or not working properly (due to mechanical defects) it has to be discarded, and a new insulin pen has to be used.



To prevent any kind of contamination, the re-usable pen should be used by a single patient only.



Optiset pre-filled pen



Before first use, the pen must be stored at room temperature for 1 to 2 hours.



Inspect the cartridge before use. It must only be used if the solution is clear, colourless, with no solid particles visible, and if it is of water-like consistency. Since Apidra is a solution, it does not require resuspension before use.



Empty pens must never be used and must be properly discarded.



To prevent any kind of contamination, the use of the pre-filled pen should remain strictly for a single patient use.



Handling of the pen



The patient should be advised to read the instructions for use included in the package leaflet carefully before using OptiSet.





Schematic diagram of the pen



Important information for use of OptiSet:



• A new needle must always be attached before each use. Only needles that are compatible for use with OptiSet must be used.



• A safety test must always be performed before each injection.



• If a new OptiSet is used the initial safety test must be done with the 8 units preset by the manufacturer.



• The dosage selector can only be turned in one direction.



• The dosage selector (change the dose) must never be turned after injection button has been pulled out.



• This pen is only for the patients use. It must not be shared with anyone else.



• If the injection is given by another person, special caution must be taken by this person to avoid accidental needle injury and transmission of infection.



• OptiSet must never be used if it is damaged or if the patient is not sure if it is working properly.



• The patient must always have a spare OptiSet available in case the OptiSet is lost or damaged.



Storage Instructions



Please check section 6.4 of this SPC for instructions on how to store OptiSet.



If OptiSet is in cool storage, it should be taken out 1 to 2 hours before injection to allow it to warm up. Cold insulin is more painful to inject.



The used OptiSet must be discarded as required by your local authorities.



Maintenance



OptiSet has to be protected from dust and dirt.



The outside of the OptiSet can be cleaned by wiping it with a damp cloth.



The pen must not be soaked, washed or lubricated as this may damage it.



OptiSet is designed to work accurately and safely. It should be handled with care. The patient should avoid situations where OptiSet may be damaged. If the patient is concerned that the OptiSet may be damaged, he must use a new one.



Step 1 Check the Insulin



After removing the pen cap, the label on the pen and the insulin reservoir should be checked to make sure it contains the correct insulin.



The appearance of insulin should also be checked: the insulin solution must be clear, colourless, with no solid particles visible, and must have a water-like consistency. Do not use this OptiSet if the insulin is cloudy, coloured or has particles.



Step 2 Attach the needle



The needle should be carefully attached straight onto the pen.



Step 3 Perform a safety test



Prior to each injection a safety test has to be performed.



For a new and unused OptiSet, a dose of 8 units is already preset by the manufacturer for the first safety test.



In-use OptiSet, a dose of 2 units has to be selected by turning the dosage selector forward till the dose arrow points to 2. The dosage selector will only turn in one direction.



The injection button should be pulled out completely in order to load the dose. The dosage selector must never be turned after the injection button has been pulled out.



The outer and inner needle caps should be removed. The outer cap should be kept to remove the used needle.



While holding the pen with the needle pointing upwards, the insulin reservoir should be tapped with the finger so that any air bubbles rise up towards the needle.



Then the injection button should be pressed all the way in.



If insulin has been expelled through the needle tip, then the pen and the needle are working properly. If no insulin appears at the needle tip, step 3 should be repeated two more times until insulin appears at the needle tip. If still no insulin comes out, change the needle, as it might be blocked and try again. If no insulin comes out after changing the needle, the OptiSet may be damaged. This OptiSet must not be used.



Step 4 Select the dose



The dose can be set in steps of 2 units, from a minimum of 2 units to a maximum of 40 units. If a dose greater than 40 units is required, it should be given as two or more injections.



The patient must always check if he has enough insulin for the dose.



The residual insulin scale on the transparent insulin reservoir shows approximately how much insulin remains in the OptiSet. This scale must not be used to set the insulin dose.



If the black plunger is at the beginning of the coloured bar, then there are approximately 40 units of insulin available.



If the black plunger is at the end of the coloured bar, then there are approximately 20 units of insulin available.



The dosage selector should be turned forward until the dose arrow points to the required dose.



Step 5 Load the dose



The injection button should be pulled out as far as it will go in order to load the pen.



The patient must always check if the selected dose is fully loaded. The injection button only goes out as far as the amount of insulin that is left in the reservoir.



The injection button allows checking the actual loaded dose. The injection button must be held out under tension during this check. The last thick line visible on the injection button shows the amount of insulin loaded. When the injection button is held out only the top part of this thick line can be seen.



Step 6 Inject the dose



The patient should be informed on the injection technique by his health care professional. The needle should be inserted into the skin



The injection button should be pressed all the way in. A clicking sound can be heard, which will stop when the injection button has been pressed in completely. Then the injection button should be held down 10 seconds before withdrawing the needle from the skin. This ensures that the full dose of insulin has been delivered.



Step 7 Remove and discard the needle



The needle should be removed after each injection and discarded. This helps prevent contamination and/or infection as well as entry of air into the insulin reservoir and leakage, of the insulin, which can cause inaccurate dosing. Needles must not be reused.



The pen cap should be replaced on the pen.

2. Qualitative And Quantitative Composition



One ml of suspension contains 10 mg cytarabine.



Each 5 ml vial contains 50 mg cytarabine.



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Suspension for injection.



White to off-white suspension.



4. Clinical Particulars



4.1 Therapeutic Indications



Intrathecal treatment of lymphomatous meningitis. In the majority of patients such treatment will be part of symptomatic palliation of the disease.



4.2 Posology And Method Of Administration



DepoCyte should be administered only under the supervision of a physician experienced in the use of cancer chemotherapeutic agents.



Posology



Adults and the elderly



For the treatment of lymphomatous meningitis, the dose for adults is 50 mg (one vial) administered intrathecally (lumbar puncture or intraventricularly via an Ommaya reservoir). The following regimen of induction, consolidation and maintenance therapy is recommended:



Induction therapy: 50 mg administered every 14 days for 2 doses (weeks 1 and 3).



Consolidation therapy: 50 mg administered every 14 days for 3 doses (weeks 5, 7 and 9) followed by an additional dose of 50 mg at week 13.



Maintenance therapy: 50 mg administered every 28 days for 4 doses (weeks 17, 21, 25 and 29).



Paediatric population



Safety and efficacy in children have not been adequately demonstrated (see section 5.1). DepoCyte is not recommended for use in children and adolescents until further data become available.



Method of administration



DepoCyte is to be administered by slow injection over a period of 1-5 minutes directly into the cerebrospinal fluid (CSF) via either an intraventricular reservoir or by direct injection into the lumbar sac. Following administration by lumbar puncture, it is recommended that the patient should be instructed to lie flat for one hour. All patients should be started on dexamethasone 4 mg twice daily either orally or intravenously for 5 days beginning on the day of injection of DepoCyte.



DepoCyte must not be administered by any other route of administration.



DepoCyte must be used as supplied; it must not be diluted (see section 6.2).



Patients should be observed by the physician for immediate toxic reactions.



If neurotoxicity develops, the dose should be reduced to 25 mg. If it persists, treatment with DepoCyte should be discontinued.



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



Patients with active meningeal infection.



4.4 Special Warnings And Precautions For Use



Patients receiving DepoCyte should be concurrently treated with corticosteroids (e.g. dexamethasone) to mitigate the symptoms of arachnoiditis (see section 4.8), which is a very common adverse reaction.



Arachnoiditis is a syndrome manifested primarily by nausea, vomiting, headache and fever. If left untreated, chemical arachnoiditis may be fatal.



Patients should be informed about the expected adverse reactions of headache, nausea, vomiting and fever, and about the early signs and symptoms of neurotoxicity. The importance of concurrent dexamethasone administration should be emphasised at the initiation of each cycle of DepoCyte treatment. Patients should be instructed to seek medical attention if signs or symptoms of neurotoxicity develop, or if oral dexamethasone is not well tolerated.



Cytarabine, when administered intrathecally, has been associated with nausea, vomiting and serious central nervous system toxicity which can lead to a permanent deficit, this includes blindness, myelopathy and other neurological toxicity.



Administration of DepoCyte in combination with other neurotoxic chemotherapeutic agents or with cranial/spinal irradiation may increase the risk of neurotoxicity.



Infectious meningitis may be associated with intrathecal administration. Hydrocephalus has also been reported, possibly precipitated by arachnoiditis.



Blockage or reduction of CSF flow may result in increased free cytarabine concentrations in the CSF with increased risk of neurotoxicity. Therefore, as with any intrathecal cytotoxic therapy, consideration should be given to the need for assessment of CSF flow before treatment is started.



Although significant systemic exposure to free cytarabine is not expected following intrathecal treatment, some effects on bone marrow function cannot be excluded. Systemic toxicity due to intravenous administration of cytarabine consists primarily of bone marrow suppression with leucopenia, thrombocytopenia and anaemia. Therefore monitoring of the haemopoietic system is advised.



Anaphylactic reactions following intravenous administration of free cytarabine have been rarely reported.



Since DepoCyte's particles are similar in size and appearance to white blood cells, care must be taken in interpreting CSF examination following administration.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



No definite interactions between DepoCyte delivered intrathecally and other medicinal products have been established.



Concomitant administration of DepoCyte with other antineoplastic agents administered by the intrathecal route has not been studied.



Intrathecal co-administration of cytarabine with other cytotoxic agents may increase the risk of neurotoxicity.



4.6 Pregnancy And Lactation



Pregnancy



Teratology studies in animals have not been conducted with DepoCyte and there are no adequate and well controlled studies in pregnant women.



Cytarabine, the active ingredient in DepoCyte, can cause foetal harm when administered systemically during pregnancy, mainly during the first trimester. Concern for foetal harm following intrathecal DepoCyte administration however, is low because systemic exposure to cytarabine is negligible. Despite the low apparent risk women of childbearing potential should not receive treatment until pregnancy is excluded and should be advised to use a reliable contraceptive method.



Given that cytarabine has a mutagenic potential which could induce chromosomal damage in the human spermatozoa, males undergoing DepoCyte treatment and their partner should be advised to use a reliable contraceptive method.



Breast-feeding



It is not known whether cytarabine is excreted in human milk following intrathecal administration. The systemic exposure to free cytarabine following intrathecal treatment with DepoCyte was negligible. Because of possible excretion in human milk and because of the potential for serious adverse reactions in nursing infants, the use of DepoCyte is not recommended in breast-feeding women.



Fertility



Fertility studies to assess the reproductive toxicity of DepoCyte have not been conducted. Because the systemic exposure to free cytarabine following intrathecal treatment with DepoCyte is negligible, the risk of impaired fertility is likely to be low (see section 5.3).



4.7 Effects On Ability To Drive And Use Machines



There have been no reports explicitly relating to effects of DepoCyte treatment on the ability to drive or use machines. However, on the basis of reported adverse reactions, patients should be advised against driving or using machines during treatment.



4.8 Undesirable Effects



In Phase 1-4 studies the most commonly reported adverse reactions associated with DepoCyte were headache (23%), arachnoiditis (16%), pyrexia (14%), weakness (13%), nausea (13%), vomiting (12%), confusion (11%), diarrhoea (11%), thrombocytopenia (10%), and fatigue (6%).

*Induction and Maintenance cycle lengths were 2 and 4 weeks, respectively, during which the patient received either 1 dose of DepoCyte or 4 doses of cytarabine. Cytarabine patients not completing all 4 doses within a cycle are counted as a complete cycle.



Nervous system disorders



DepoCyte has the potential of producing serious neurological toxicity.



Intrathecal administration of cytarabine may cause myelopathy (3%) and other neurologic toxicities sometimes leading to a permanent neurological deficit. Following intrathecal administration of DepoCyte, serious central nervous system toxicity, including persistent convulsions (7%), extreme somnolence (3%), hemiplegia (1%), visual disturbances including blindness (1%), deafness (3%) and cranial nerve palsies (3%) have been reported. Symptoms and signs of peripheral neuropathy, such as pain (1%), numbness (3%), paresthesia (3%), hypoaesthesia (2%), weakness (13%), and impaired bowel (3%) and bladder control (incontinence) (1%), have also been observed and in some cases this combination of neurological signs and symptoms has been reported as Cauda equina syndrome (3%).

All patients receiving DepoCyte should be treated concurrently with dexamethasone to mitigate the symptoms of arachnoiditis. Toxic effects may be related to a single dose or to cumulative doses. Because toxic effects can occur at any time during therapy (although they are most likely within 5 days of administration), patients receiving DepoCyte therapy should be monitored continuously for the development of neurotoxicity. If patients develop neurotoxicity, subsequent doses of DepoCyte should be reduced, and treatment should be discontinued if toxicity persists.



Arachnoiditis, a very common adverse reaction associated with DepoCyte, is a syndrome manifested by several adverse reactions. The incidence of these adverse reactions, possibly reflecting meningeal irritation, are headache (24%), nausea (18%), vomiting (17%), pyrexia (12%), neck stiffness (3%), neck pain (4%), back pain (7%), meningism (<1%), convulsions (6%), hydrocephalus (2%), and CSF pleocytosis with or without altered state of consciousness (1%). Table 3 below lists these reactions for patients treated DepoCyte, and for patients treated with methotrexate and cytarabine as well.

*Cycle length was 2 weeks during which the patient received either 1 dose of DepoCyte or 4 doses of cytarabine or methotrexate. Cytarabine and methotrexate patients not completing all 4 doses are counted as a fraction of a cycle.



Investigations



Transient elevations in CSF protein and white blood cells have been observed in patients following DepoCyte administration, and have also been noted after intrathecal treatment with methotrexate or cytarabine. These reactions have been reported mainly from post-marketing experience with DepoCyte as spontaneous case reports. Because these reactions are reported from a population of uncertain size, it is not possible to reliably estimate their frequency.



4.9 Overdose



No overdoses with DepoCyte have been reported. An overdose with DepoCyte may be associated with severe arachnoiditis including encephalopathy.



In an early uncontrolled study without dexamethasone prophylaxis, single doses up to 125 mg were administered. One patient at the 125 mg dose level died of encephalopathy 36 hours after receiving DepoCyte intraventricularly. This patient, however, was also receiving concomitant whole brain irradiation and had previously received intraventricular methotrexate.



There is no antidote for intrathecal DepoCyte or unencapsulated cytarabine released from DepoCyte. Exchange of cerebrospinal fluid with isotonic sodium chloride solution has been carried out in a case of intrathecal overdose of free cytarabine and such a procedure may be considered in the case of DepoCyte overdose. Management of overdose should be directed at maintaining vital functions.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Antimetabolites, pyrimidine analogues, ATC code L01BC01



DepoCyte is a sustained-release formulation of cytarabine, designed for direct administration into the cerebrospinal fluid (CSF).



Cytarabine is a cell-cycle phase specific antineoplastic agent, affecting cells only during the S-phase of cell division. Intracellularly, cytarabine is converted into cytarabine-5'-triphosphate (ara-CTP), which is the active metabolite. The mechanism of action is not completely understood, but it appears that ara-CTP acts primarily through inhibition of DNA synthesis. Incorporation into DNA and RNA may also contribute to cytarabine cytotoxicity. Cytarabine is cytotoxic to a wide variety of proliferating mammalian cells in culture.



For cell-cycle phase specific antimetabolites the duration of exposure of neoplastic cells to cytotoxic concentrations is an important determination of efficacy.



In vitro studies, examining more than 60 cell lines, demonstrated that the median cytarabine concentration resulting in 50% growth inhibition (IC50) was approximately 10 μM (2.4 μg/ml) for two days of exposure and 0.1 μM (0.024 μg/ml) for 6 days of exposure. The studies also demonstrated susceptibility of many solid tumour cell lines to cytarabine, particularly after longer periods of exposure to cytarabine.



In an open-label, active-controlled, multicentre clinical study, 35 patients with lymphomatous meningitis (with malignant cells found on CSF cytology) were randomised to intrathecal therapy with either DepoCyte (n=18) or unencapsulated cytarabine (n=17). During the 1 month Induction phase of treatment, DepoCyte was administered intrathecally as 50 mg every 2 weeks, and unencapsulated cytarabine as 50 mg twice a week. Patients who did not respond discontinued protocol treatment after 4 weeks. Patients who achieved a response (defined as clearing of the CSF of malignant cells in the absence of progression of neurological symptoms) went on to receive Consolidation and Maintenance therapy for up to 29 weeks.



Responses were observed in 13/18 (72%, 95% confidence intervals: 47, 90) of DepoCyte patients versus 3/17 (18% patients, 95% confidence intervals: 4, 43) in the unencapsulated cytarabine arm. A statistically significant association between treatment and response was observed (Fisher's exact test p-value = 0.002). The majority of DepoCyte patients went on beyond Induction to receive additional therapy. DepoCyte patients received a median of 5 cycles (doses) per patient (range 1 to 10 doses) with a median time on therapy of 90 days (range 1 to 207 days).



No statistically significant differences were noted in secondary endpoints such as duration of response, progression-free survival, neurological signs and symptoms, Karnofsky performance status, quality of life and overall survival. Median progression-free survival (defined as time to neurological progression or death) for all treated patients was 77 versus 48 days for DepoCyte versus unencapsulated cytarabine, respectively. The proportion of patients alive at 12 months was 24% for DepoCyte versus 19% for unencapsulated cytarabine.



In an open-label non-comparative dose escalation study in 18 paediatric patients (4 to 19 years) with leukaemic meningitis or neoplastic meningitis due to primary brain tumour, an intrathecal dose of 35 mg was identified as the maximum tolerated dose.



5.2 Pharmacokinetic Properties



Analysis of the available pharmacokinetic data shows that following intrathecal DepoCyte administration in patients, either via the lumbar sac or by intraventricular reservoir, peaks of free cytarabine were observed within 5 hours in both the ventricle and lumbar sac. These peaks were followed by a biphasic elimination profile consisting of an initial sharp decline and subsequent slow decline with a terminal phase half-life of 100 to 263 hours over a dose-range of 12.5 mg to 75 mg. In contrast, intrathecal administration of 30 mg free cytarabine has shown a biphasic CSF concentration profile with a terminal phase half-life of about 3.4 hours.



Pharmacokinetic parameters of DepoCyte (75 mg) in neoplastic meningitis patients in whom the medicinal product was administered either intraventricularly or by lumbar puncture suggest that exposure to the active substance in the ventricular or lumbar spaces is similar regardless of the route of administration. In addition, compared with free cytarabine, the formulation increases the biological half-life by a factor of 27 to 71 depending upon the route of administration and the compartment sampled. Encapsulated cytarabine concentrations and the counts of the lipid particles in which the cytarabine is encapsulated in followed a similar distribution pattern. AUCs of free and encapsulated cytarabine after ventricular injection of DepoCyte appeared to increase linearly with increasing dose, indicating that the release of cytarabine from DepoCyte and the pharmacokinetics of cytarabine are linear in human CSF.



The transfer rate of cytarabine from CSF to plasma is slow and the conversion to uracil arabinoside (ara-U), the inactive metabolite, in the plasma is fast. Systemic exposure to cytarabine was determined to be negligible following intrathecal administration of 50 mg and 75 mg of DepoCyte.



Biotransformation and elimination



The primary route of elimination of cytarabine is metabolism to the inactive compound ara-U, (1-β-D-arabinofuranosyluracil or uracil arabinoside) followed by urinary excretion of ara-U. In contrast with systemically administered cytarabine which is rapidly metabolised to ara-U, conversion to ara-U in the CSF is negligible after intrathecal administration because of the significantly lower cytidine deaminase activity in the CNS tissues and CSF. The CSF clearance rate of cytarabine is similar to the CSF bulk flow rate of 0.24 ml/min.



The distribution and clearance of cytarabine and of the predominant phospholipid component of the lipid particle (DOPC) following intrathecal administration of DepoCyte was evaluated in rodents. Radiolabels for cytarabine and DOPC were distributed rapidly throughout the neuraxis. More than 90% of cytarabine was excreted by day 4 and an additional 2.7% by 21 days. The results suggest that the lipid components undergo hydrolysis and are largely incorporated in the tissues following breakdown in the intrathecal space.



5.3 Preclinical Safety Data



A review of the toxicological data available for the constituent lipids (DOPC and DPPG) or similar phospholipids to those in DepoCyte indicates that such lipids are well tolerated in various animal species even when administered for prolonged periods at doses in the g/kg range.



The results of acute and subacute toxicity studies performed in monkeys suggested that intrathecal DepoCyte was tolerated up to a dose of 10 mg (comparable to a human dose of 100 mg). Slight to moderate inflammation of the meninges in the spinal cord and brain and/or astrocytic activation were observed in animals receiving intrathecal DepoCyte. These changes were believed to be consistent with the toxic effects of other intrathecal agents such as unencapsulated cytarabine. Similar changes (generally described as minimal to slight) were also observed in some animals receiving DepoFoam alone (DepoCyte vesicles without cytarabine) but not in sodium chloride solution control animals. Mouse, rat and dog studies have shown that free cytarabine is highly toxic for the haemopoietic system.



No carcinogenicity, mutagenicity or impairment of fertility studies have been conducted with DepoCyte. The active ingredient, cytarabine, was mutagenic in in vitro tests and was clastogenic in vitro (chromosome aberrations and sister chromatid exchange in human leukocytes) and in vivo (chromosome aberrations and sister chromatid exchange assay in rodent bone marrow, mouse micronucleus assay). Cytarabine caused the transformation of hamster embryo cells and rat H43 cells in vitro. Cytarabine was clastogenic to meiotic cells; a dose-dependent increase in sperm-head abnormalities and chromosomal aberrations occurred in mice given intraperitoneal (i.p.) cytarabine. No studies assessing the impact of cytarabine on fertility are available in the literature. Because the systemic exposure to free cytarabine following intrathecal treatment with DepoCyte was negligible, the risk of impaired fertility is likely to be low.

After first opening: 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 4 hours at 18 to 22°C.



6.4 Special Precautions For Storage



Store in a refrigerator (2°C - 8°C).



Do not freeze.



6.5 Nature And Contents Of Container



Type I glass vial closed with a fluororesin faced butyl rubber stopper and sealed with an aluminium flip-off seal containing 50 mg cytarabine in 5 ml suspension.



DepoCyte is supplied in individual cartons each containing one single-dose vial.



6.6 Special Precautions For Disposal And Other Handling



Preparation of DepoCyte



Given its toxic nature, special precautions should be taken in handling DepoCyte. See 'Precautions for the handling and disposal of DepoCyte' below.



Vials should be allowed to warm to room temperature (18°C -22°C) for a minimum of 30 minutes and be gently inverted to resuspend the particles immediately prior to withdrawal from the vial. Vigorous shaking should be avoided. No further reconstitution or dilution is required.



DepoCyte administration



DepoCyte must only be administered by the intrathecal route.



DepoCyte should be withdrawn from the vial immediately before administration. Since it is a single use vial and does not contain any preservative, the medicinal product should be used within 4 hours of withdrawal from the vial. Unused medicinal product must be discarded and not used subsequently. DepoCyte must not be mixed with any other medicinal products (see section 6.2). The suspension must not be diluted.



In-line filters must not be used when administering DepoCyte. DepoCyte is administered directly into the CSF via an intraventricular reservoir or by direct injection into the lumbar sac. DepoCyte should be injected slowly over a period of 1-5 minutes. Following administration by lumbar puncture, the patient should be instructed to lie flat for one hour. Patients should be observed by the physician for immediate toxic reactions.



All patients should be started on dexamethasone 4 mg twice daily either orally or intravenously for 5 days beginning on the day of DepoCyte injection.



Precautions for the handling and disposal of DepoCyte



The following protective recommendations are given due to the toxic nature of this substance:



• personnel should be trained in good technique for handling anticancer agents;



• male and female staff who are trying to conceive and female staff who are pregnant should be excluded from working with the substance;



• personnel must wear protective clothing: goggles, gowns, disposable gloves and masks;



• a designated area should be defined for preparation (preferably under a laminar flow system). The work surface should be protected by disposable, plastic backed, absorbent paper;



• all items used during administration or cleaning should be placed in high risk, waste-disposal bags for high temperature incineration;



• in the event of accidental contact with the skin, exposed areas should be washed immediately with soap and water;



• in the event of accidental contact with the mucous membranes, exposed areas should be treated immediately by copious lavage with water; medical attention should be sought.
