Daptomycin 350 mg Powder for Solution for Injection or Infusion

Active substance: DaptomycinRx — prescription only

Source: electronic medicines compendium (emc)
Official leaflet: Read the PIL on emc

What it is and what it is used for

The active substance in Daptomycin Tillomed powder for solution for injection or infusion is daptomycin. Daptomycin is an antibacterial that can stop the growth of certain bacteria. Daptomycin is used in adults and in children and adolescents (age from 1 to 17 years) to treat infections of the skin and the tissues below the skin. It is also used to treat infections in the blood when associated with skin infection.

Daptomycin is also used in adults to treat infections in the tissues that line the inside of the heart (including heart valves) which are caused by a type of bacteria called Staphylococcus aureus. It is also used to treat infections in the blood caused by the same type of bacteria when associated with heart infection.

Depending on the type of infection(s) that you have, your doctor may also prescribe other antibacterials while you are receiving treatment with Daptomycin. The name of your medicine is Daptomycin Tillomed Powder for Solution for Injection or Infusion, but will be referred to as Daptomycin throughout this leaflet."

What you need to know before you take it

You should not be given Daptomycin If you are allergic to daptomycin or to sodium hydroxide or to any of the other ingredients of this medicine (listed in section 6). If this applies to you, tell your doctor or nurse. If you think you may be allergic, ask your doctor or nurse for advice.

Warnings and precautions Talk to your doctor or nurse before you are given Daptomycin. - If you have, or have previously had kidney problems. Your doctor may need to change the dose of Daptomycin (see section 3 of this leaflet). - Occasionally, patients receiving Daptomycin may develop tender or aching muscles or

Daptomycin Tillomed 350 mg Powder for Solution for Injection or Infusion Daptomycin Tillomed 500 mg Powder for Solution for Injection or Infusion

muscle weakness (see section 4 of this leaflet for more information). If this happens tell your doctor. Your doctor will make sure you have a blood test and will advise whether or not to continue with Daptomycin. The symptoms generally go away within a few days of stopping Daptomycin. - If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores, or serious kidney problems after taking Daptomycin.

- If you are very overweight. There is a possibility that your blood levels of Daptomycin could be higher than those found in persons of average weight and you may need careful monitoring in case of side effects. If any of these applies to you, tell your doctor or nurse before you are given Daptomycin.

Tell your doctor straight away if you develop any of the following symptoms: - Serious, acute allergic reactions have been observed in patients treated with nearly all antibacterial agents, including Daptomycin. The symptoms can include wheezing, difficulty breathing, swelling of the face, neck and throat, rashes and hives, or fever. - Serious skin disorders have been reported with the use of Daptomycin. The symptoms that occur with these skin disorders can include: - a new or worsening fever, - red raised or fluid-filled skin spots which may start in your armpits or on your chest or groin areas and which can spread over a large area of your body, - blisters or sores in your mouth or on your genitals. - A serious kidney problem has been reported with the use of Daptomycin. The symptoms can include fever and rash. - Any unusual tingling or numbness of the hands or feet, loss of feeling or difficulties with movements. If this happens, tell your doctor who will decide whether you should continue the treatment. - Diarrhoea, especially if you notice blood or mucus, or if diarrhoea becomes severe or persistent. - New or worsening fever, cough or difficulty breathing. These may be signs of a rare but serious lung disorder called eosinophilic pneumonia. Your doctor will check the condition of your lungs and decide whether or not you should continue Daptomycin treatment.

Daptomycin may interfere with laboratory tests that measure how well your blood is clotting. The results can suggest poor blood clotting when, in fact, there is no problem. Therefore, it is important that your doctor takes into account that you are receiving Daptomycin. Please inform your doctor that you are on treatment with Daptomycin.

Your doctor will perform blood tests to monitor the health of your muscles both before you start treatment and frequently during treatment with Daptomycin.

Children and adolescents Daptomycin should not be administered to children below one year of age as studies in animals have indicated that this age group may experience severe side effects.

Use in elderly People over the age of 65 can be given the same dose as other adults, provided their kidneys are working well.

Other medicines and Daptomycin Tell your doctor or nurse if you are taking, have recently taken or might take any other medicines. It is particularly important that you mention the following: - Medicines called statins or fibrates (to lower cholesterol) or ciclosporin (a medicinal product used in transplantation to prevent organ rejection or for other conditions, e.g. rheumatoid arthritis or atopic dermatitis). It is possible that the risk of side effects affecting the muscles may be higher when any of these medicines (and some others that can affect muscles) is taken during treatment with Daptomycin. Your doctor may decide not to give you Daptomycin or to stop the other medicine for a while.

- Pain killing medicines called non-steroidal anti-inflammatory drugs (NSAIDs) or COX-2 inhibitors (e.g. celecoxib). These could interfere with the effects of Daptomycin in the kidney. - Oral anti-coagulants (e.g. warfarin), which are medicines that prevent blood from clotting. It may be necessary for your doctor to monitor your blood clotting times.

Pregnancy and breast-feeding Daptomycin is not usually given to pregnant women. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before you are given this medicine.

Do not breast-feed if you are receiving Daptomycin, because it may pass into your breast milk and could affect the baby.

Driving and using machines Daptomycin has no known effects on the ability to drive or use machines.

Daptomycin Tillomed contains sodium This medicine contains less than 1 mmol sodium (23 mg) per vial, i.e. essentially 'sodium- free'.

How to take it

Daptomycin will usually be given to you by a doctor or a nurse.

Adults (18 years of age and above) The dose will depend on how much you weigh and the type of infection being treated. The usual dose for adults is 4 mg for every kilogram (kg) of body weight once daily for skin infections or 6 mg for every kg of body weight once daily for a heart infection or a blood infection associated with skin or heart infection. In adult patients, this dose is given directly into your blood stream (into a vein), either as an infusion lasting about 30 minutes or as an injection lasting about 2 minutes. The same dose is recommended in people aged over 65 years provided their kidneys are working well. If your kidneys do not work well, you may receive Daptomycin less often, e.g. once every other day. If you are receiving dialysis, and your next dose of Daptomycin is due on a dialysis day, you will be usually given Daptomycin after the dialysis session.

Children and adolescents (1 to 17 years of age) The dose for children and adolescents (1 to 17 years of age) will depend on the age of patient and the type of infection being treated. This dose is given directly into the blood stream (into a vein), as an infusion lasting about 30-60 minutes. A course of treatment usually lasts for 1 to 2 weeks for skin infections. For blood or heart infections and skin infections your doctor will decide how long you should be treated.

Detailed instructions for use and handling are given at the end of the leaflet.

The following information is intended for healthcare professionals only

Important: Please refer to the Summary of Product Characteristics before prescribing.

Instructions for use and handling

In adults, daptomycin may be administered intravenously as an infusion over 30 minutes or as an injection over 2 minutes. Unlike in adults, daptomycin should not be administered by injection over a 2 minute period in paediatric patients. Paediatric patients 7 to 17 years old should receive daptomycin infused over 30 minutes. In paediatric patients under 7 years old receiving a 9-12 mg/kg dose, daptomycin should be administered over 60 minutes. Preparation of the solution for infusion requires an additional dilution step as detailed below.

Daptomycin given as an intravenous infusion over 30 or 60 minutes

A 50 mg/ml concentration of Daptomycin for infusion can be achieved by reconstituting the lyophilised product with 7 ml (for Daptomycin 350 mg powder) or 10 ml (for Daptomycin 500 mg powder) of sodium chloride 9 mg/ml (0.9%) solution for injection.

The lyophilised product takes approximately 15 minutes to dissolve. The fully reconstituted product will appear clear and may have a few small bubbles or foam around the edge of the vial.

To prepare Daptomycin for intravenous infusion, please adhere to the following instructions: Aseptic technique should be used throughout to reconstitute or dilute lyophilised Daptomycin. For Reconstitution: 1. The polypropylene flip off cap should be removed to expose the central portions of the rubber stopper. Wipe the top of the rubber stopper with an alcohol swab or other antiseptic solution and allow to dry. After cleaning, do not touch the rubber stopper or allow it to touch any other surface. Draw 7 ml (for Daptomycin 350 mg powder) or 10 ml (for Daptomycin 500 mg powder) of sodium chloride 9 mg/ml (0.9%) solution for injection into a syringe using a sterile transfer needle that is 21 gauge or smaller in diameter, or a needleless device, then slowly inject through the centre of the rubber stopper into the vial pointing the needle towards the wall of the vial. 2. The vial should be gently rotated to ensure complete wetting of the product and then allowed to stand for 10 minutes. 3. Finally the vial should be gently rotated/swirled for a few minutes as needed to obtain a clear reconstituted solution. Vigorous shaking/agitation should be avoided to prevent foaming of the product. 4. The reconstituted solution should be checked carefully to ensure that the product is in solution and visually inspected for the absence of particulates prior to use. Reconstituted solutions of Daptomycin range in colour from pale yellow to light brown. 5. The reconstituted solution should then be diluted with sodium chloride 9 mg/ml (0.9%) (typical volume 50 ml).

For Dilution: 1. Slowly remove the appropriate reconstituted liquid (50 mg daptomycin/ml) from the vial using a new sterile needle that is 21 gauge or smaller in diameter by inverting the vial in order to allow the solution to drain towards the stopper. Using a syringe, insert the needle into the inverted vial. Keeping the vial inverted, position the needle tip at the very bottom of the solution in the vial when drawing the solution into the syringe. Before removing the needle from the vial, pull the plunger all the way back to the end of the syringe barrel in order to remove the required solution from the inverted vial. 2. Expel air, large bubbles, and any excess solution in order to obtain the required dose. 3. Transfer the required reconstituted dose into 50 ml sodium chloride 9 mg/ml (0.9%).

4. The reconstituted and diluted solution should then be infused intravenously over 30 or 60 minutes.

Daptomycin is not physically or chemically compatible with glucose-containing solutions. The following have been shown to be compatible when added to daptomycin-containing infusion solutions: aztreonam, ceftazidime, ceftriaxone, gentamicin, fluconazole, levofloxacin, dopamine, heparin and lidocaine.

The combined storage time (reconstituted solution in vial and diluted solution in infusion bag) at 25°C must not exceed 12 hours (24 hours if refrigerated).

Stability of the diluted solution in infusion bags is established as 12 hours at 25°C or 24 hours if stored under refrigeration at 2°C – 8°C.

Daptomycin given as 2-minute intravenous injection (adult patients only)

Water should not be used for reconstitution of Daptomycin for intravenous injection. Daptomycin should only be reconstituted with sodium chloride 9 mg/ml (0.9%).

A 50 mg/ml concentration of Daptomycin for injection is obtained by reconstituting the lyophilised product with 7 ml (for Daptomycin 350 mg powder) or 10 ml (for Daptomycin 500 mg powder) of sodium chloride 9 mg/ml (0.9%) solution for injection.

The lyophilised product takes approximately 15 minutes to dissolve. The fully reconstituted product will appear clear and may have a few small bubbles or foam around the edge of the vial.

To prepare Daptomycin for intravenous injection, please adhere to the following instructions: Aseptic technique should be used throughout to reconstitute lyophilised Daptomycin. 1. The polypropylene flip off cap should be removed to expose the central portions of the rubber stopper. Wipe the top of the rubber stopper with an alcohol swab or other antiseptic solution and allow to dry. After cleaning, do not touch the rubber stopper or allow it to touch any other surface.

The vial should be gently rotated to ensure complete wetting of the product and then allowed to stand for 10 minutes. 3. Finally the vial should be gently rotated/swirled for a few minutes as needed to obtain a clear reconstituted solution. Vigorous shaking/agitation should be avoided to prevent foaming of the product. 4. The reconstituted solution should be checked carefully to ensure that the product is in solution and visually inspected for the absence of particulates prior to use. Reconstituted solutions of Daptomycin range in colour from pale yellow to light brown. 5. Slowly remove the reconstituted liquid (50 mg daptomycin/ml) from the vial using a sterile needle that is 21 gauge or smaller in diameter. 6. Invert the vial in order to allow the solution to drain towards the stopper. Using a new syringe, insert the needle into the inverted vial. Keeping the vial inverted, position the needle tip at the very bottom of the solution in the vial when drawing the solution into the syringe. Before removing the needle from the vial, pull the plunger all the way back to the end of the syringe barrel in order to remove all of the solution from the inverted vial. 7. Replace needle with a new needle for the intravenous injection. 8. Expel air, large bubbles, and any excess solution in order to obtain the required dose. 9. The reconstituted solution should then be injected intravenously slowly over 2 minutes.

Chemical and physical in-use stability on the reconstituted solution in the vial has been demonstrated for 12 hours at 25°C and up to 48 hours if stored under refrigeration (2°C – 8°C).

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

aseptic conditions.

This medicinal product must not be mixed with other medicinal products except those mentioned above.

Daptomycin vials are for single-use only. Any unused portion remaining in the vial should be discarded.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Daptomycin is indicated for the treatment of the following infections (see sections 4.4 and 5.1).

- Adult and paediatric (1 to 17 years of age) patients with complicated skin and soft-tissue infections (cSSTI).

- Adult patients with right-sided infective endocarditis (RIE) due to Staphylococcus aureus. It is recommended that the decision to use daptomycin should take into account the antibacterial susceptibility of the organism and should be based on expert advice. See sections 4.4 and 5.1.

- Adult and paediatric (1 to 17 years of age) patients with Staphylococcus aureus bacteraemia (SAB). In adults, use in bacteraemia should be associated with RIE or with cSSTI, while in paediatric patients, use in bacteraemia should be associated with cSSTI.

Daptomycin is active against Gram positive bacteria only (see section 5.1). In mixed infections where Gram negative and/or certain types of anaerobic bacteria are suspected, daptomycin should be co-administered with appropriate antibacterial agent(s).

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

4.2. Posology and method of administration

Clinical studies in patients employed infusion of daptomycin over at least 30 minutes. There is no clinical experience in patients with the administration of daptomycin as an injection over 2 minutes. This mode of administration was only studied in healthy subjects. However, when compared with the same doses given as intravenous infusions over 30 minutes there were no clinically important differences in the pharmacokinetics and safety profile of daptomycin (see also sections 4.8 and 5.2).

Posology

Adults

- cSSTI without concurrent SAB: Daptomycin 4 mg/kg is administered once every 24 hours for 7-14 days or until the infection is resolved (see section 5.1).

- cSSTI with concurrent SAB: Daptomycin 6 mg/kg is administered once every 24 hours. See below for dose adjustments in patients with renal impairment. The duration of therapy may need to be longer than 14 days in accordance with the perceived risk of complications in the individual patient.

- Known or suspected RIE due to Staphylococcus aureus: Daptomycin 6 mg/kg is administered once every 24 hours. See below for dose adjustments in patients with renal impairment. The duration of therapy should be in accordance with available official recommendations.

Daptomycin is administered intravenously in 0.9% sodium chloride (see section 6.6). Daptomycin should not be used more frequently than once a day.

Creatine phosphokinase (CPK) levels must be measured at baseline and at regular intervals (at least weekly) during treatment (see section 4.4).

Renal impairment

Daptomycin is eliminated primarily by the kidney.

Due to limited clinical experience (see table and footnotes below) daptomycin should only be used in adult patients with any degree of renal impairment (CrCl < 80 ml/min) when it is considered that the expected clinical benefit outweighs the potential risk. The response to treatment, renal function and creatine phosphokinase (CPK) levels should be closely monitored in all patients with any degree of renal impairment (see also sections 4.4 and 5.2). The dosage regimen for daptomycin in paediatric patients with renal impairment has not been established.

(1) The safety and efficacy of the dose interval adjustment have not been evaluated in controlled clinical trials and the recommendation is based on pharmacokinetic studies and modelling results (see sections 4.4 and 5.2).

(2) The same dose adjustments, which are based on pharmacokinetic data in volunteers including PK modelling results, are recommended for adult patients on haemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Whenever possible, daptomycin should be administered following the completion of dialysis on dialysis days (see section 5.2).

Hepatic impairment

No dose adjustment is necessary when administering daptomycin to patients with mild or moderate hepatic impairment (Child-Pugh Class B) (see section 5.2). No data are available in patients with severe hepatic impairment (Child-Pugh Class C). Therefore, caution should be exercised if daptomycin is given to such patients.

Elderly patients

The recommended doses should be used in elderly patients except those with severe renal impairment (see above and section 4.4).

(1) Minimum duration of daptomycin for paediatric SAB should be in accordance with the perceived risk of complications in the individual patient. The duration of daptomycin may need to be longer than 14 days in accordance with the perceived risk of complications in the individual patient. In the paediatric SAB study, the mean duration of IV daptomycin was 12 days, with a range of 1 to 44 days. The duration of therapy should be in accordance with available official recommendations.

Daptomycin is administered intravenously in 0.9 % sodium chloride (see section 6.6). Daptomycin should not be used more frequently than once a day.

Creatine phosphokinase (CPK) levels must be measured at baseline and at regular intervals (at least weekly) during treatment (see section 4.4).

Paediatric patients below the age of one year should not be given daptomycin due to the risk of potential effects on muscular, neuromuscular and/or nervous systems (either peripheral and/or central) that were observed in neonatal dogs (see section 5.3).

Method of administration

In adults, daptomycin is given by intravenous infusion (see section 6.6) and administered over a 30-minute period or by intravenous injection (see section 6.6) and administered over a 2-minute period.

In paediatric patients aged 7 to 17 years, daptomycin is given by intravenous infusion over a 30-minute period (see section 6.6). In paediatric patients aged 1 to 6 years, daptomycin is given by intravenous infusion over a 60-minute period (see section 6.6).

For instructions on reconstitution and dilution of the medicinal product before administration, see section 6.6.

4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.4. Special warnings and precautions for use

General

If a focus of infection other than cSSTI or RIE is identified after initiation of daptomycin therapy consideration should be given to instituting alternative antibacterial therapy that has been demonstrated to be efficacious in the treatment of the specific type of infection(s) present.

Anaphylaxis/hypersensitivity reactions

Anaphylaxis/hypersensitivity reactions have been reported with daptomycin. If an allergic reaction to daptomycin occurs, discontinue use and institute appropriate therapy.

Pneumonia

It has been demonstrated in clinical studies that daptomycin is not effective in the treatment of pneumonia. Daptomycin is therefore not indicated for the treatment of pneumonia.

RIE due to Staphylococcus aureus

Clinical data on the use of daptomycin to treat RIE due to Staphylococcus aureus are limited to 19 adult patients (see “Clinical efficacy in adults” in section 5.1). The safety and efficacy of daptomycin in children and adolescents aged below 18 years with right-sided infective endocarditis (RIE) due to Staphylococcus aureus have not been established.

The efficacy of daptomycin in patients with prosthetic valve infections or with left-sided infective endocarditis due to Staphylococcus aureus has not been demonstrated.

Deep-seated infections

Patients with deep-seated infections should receive any required surgical interventions (e.g. debridement, removal of prosthetic devices, valve replacement surgery) without delay.

Enterococcal infections

There is insufficient evidence to be able to draw any conclusions regarding the possible clinical efficacy of daptomycin against infections due to enterococci, including Enterococcus faecalis and Enterococcus faecium. In addition, dose regimens of daptomycin that might be appropriate for the treatment of enterococcal infections, with or without bacteraemia, have not been identified. Failures with daptomycin in the treatment of enterococcal infections that were mostly accompanied by bacteraemia have been reported. In some instances treatment failure has been associated with the selection of organisms with reduced susceptibility or frank resistance to daptomycin (see section 5.1).

Non-susceptible micro-organisms

The use of antibacterials may promote the overgrowth of non-susceptible micro-organisms. If superinfection occurs during therapy, appropriate measures should be taken.

Clostridioides difficile-associated diarrhoea (CDAD) has been reported with daptomycin (see section 4.8). If CDAD is suspected or confirmed, daptomycin may need to be discontinued and appropriate treatment instituted as clinically indicated.

Drug/laboratory test interactions

False prolongation of prothrombin time (PT) and elevation of international normalised ratio (INR) have been observed when certain recombinant thromboplastin reagents are utilised for the assay (see also section 4.5).

Creatine phosphokinase and myopathy

Increases in plasma creatine phosphokinase (CPK; MM isoenzyme) levels associated with muscular pains and/or weakness and cases of myositis, myoglobinaemia and rhabdomyolysis have been reported during therapy with daptomycin (see also sections 4.5, 4.8 and 5.3). In clinical studies, marked increases in plasma CPK to > 5x Upper Limit of Normal (ULN) without muscle symptoms occurred more commonly in daptomycin-treated patients (1.9%) than in those that received comparators (0.5%). Therefore, it is recommended that:

• Plasma CPK should be measured at baseline and at regular intervals (at least once weekly) during therapy in all patients.

• CPK should be measured more frequently (e.g. every 2-3 days at least during the first two weeks of treatment) in patients who are at higher risk of developing myopathy. For example, patients with any degree of renal impairment (creatinine clearance < 80 ml/min; see also section 4.2), including those on haemodialysis or CAPD, and patients taking other medicinal products known to be associated with myopathy (e.g. HMG-CoA reductase inhibitors, fibrates and ciclosporin).

• It cannot be ruled out that those patients with CPK greater than 5 times upper limit of normal at baseline may be at increased risk of further increases during daptomycin therapy. This should be taken into account when initiating daptomycin therapy and, if daptomycin is given, these patients should be monitored more frequently than once weekly.

• Daptomycin should not be administered to patients who are taking other medicinal products associated with myopathy unless it is considered that the benefit to the patient outweighs the risk.

• Patients should be reviewed regularly while on therapy for any signs or symptoms that might represent myopathy.

• Any patient that develops unexplained muscle pain, tenderness, weakness or cramps should have CPK levels monitored every 2 days. Daptomycin should be discontinued in the presence of unexplained muscle symptoms if the CPK level reaches greater than 5 times upper limit of normal.

Peripheral neuropathy

Patients who develop signs or symptoms that might represent a peripheral neuropathy during therapy with daptomycin should be investigated and consideration should be given to discontinuation of daptomycin (see sections 4.8 and 5.3).

Paediatric population

Paediatric patients below the age of one year should not be given daptomycin due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) that were observed in neonatal dogs (see section 5.3).

Eosinophilic pneumonia

Eosinophilic pneumonia has been reported in patients receiving daptomycin (see section 4.8). In most reported cases associated with daptomycin, patients developed fever, dyspnoea with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates or organising pneumonia. The majority of cases occurred after more than 2 weeks of treatment with daptomycin and improved when daptomycin was discontinued and steroid therapy was initiated. Recurrence of eosinophilic pneumonia upon re- exposure has been reported. Patients who develop these signs and symptoms while receiving daptomycin should undergo prompt medical evaluation, including, if appropriate, bronchoalveolar lavage, to exclude other causes (e.g. bacterial infection, fungal infection, parasites, other medicinal products). Daptomycin should be discontinued immediately and treatment with systemic steroids should be initiated when appropriate.

Severe cutaneous adverse reactions

Severe cutaneous adverse reactions (SCARs) including drug reaction with eosinophilia and systemic symptoms (DRESS) and vesiculobullous rash with or without mucous membrane involvement (Stevens-Johnson Syndrome (SJS) or Toxic Epidermal Necrolysis (TEN)), which could be life-threatening or fatal, have been reported with daptomycin (see section 4.8). At the time of prescription, patients should be advised of the signs and symptoms of severe skin reactions, and be closely monitored. If signs and symptoms suggestive of these reactions appear, daptomycin should be discontinued immediately and an alternative treatment should be considered. If the patient has developed a severe cutaneous adverse reaction with the use of daptomycin, treatment with daptomycin must not be restarted in this patient at any time.

Tubulointerstitial nephritis

Tubulointerstitial nephritis (TIN) has been reported in post-marketing experience with daptomycin. Patients who develop fever, rash, eosinophilia and/or new or worsening renal impairment while receiving daptomycin should undergo medical evaluation. If TIN is suspected, daptomycin should be discontinued promptly and appropriate therapy and/or measures should be taken.

Renal impairment

Renal impairment has been reported during treatment with daptomycin. Severe renal impairment may in itself also pre-dispose to elevations in daptomycin levels which may increase the risk of development of myopathy (see above).

An adjustment of daptomycin dose interval is needed for adult patients whose creatinine clearance is < 30 ml/min (see sections 4.2 and 5.2). The safety and efficacy of the dose interval adjustment have not been evaluated in controlled clinical trials and the recommendation is mainly based on pharmacokinetic modelling data. Daptomycin should only be used in such patients when it is considered that the expected clinical benefit outweighs the potential risk.

Caution is advised when administering daptomycin to patients who already have some degree of renal impairment (creatinine clearance < 80 ml/min) before commencing therapy with daptomycin. Regular monitoring of renal function is advised (see also section 5.2).

In addition, regular monitoring of renal function is advised during concomitant administration of potentially nephrotoxic agents, regardless of the patient's pre-existing renal function (see also section 4.5).

The dosage regimen for daptomycin in paediatric patients with renal impairment has not been established.

Obesity

In obese subjects with Body Mass Index (BMI) > 40 kg/m2 but with creatinine clearance > 70 ml/min, the AUC0-∞ daptomycin was significantly increased (mean 42% higher) compared with non-obese matched controls. There is limited information on the safety and efficacy of daptomycin in the very obese and so caution is recommended. However, there is currently no evidence that a dose reduction is required (see section 5.2).

'This medicinal product contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially 'sodium-free''.

4.5. Interaction with other medicinal products and other forms of interaction

Daptomycin undergoes little to no Cytochrome P450 (CYP450)-mediated metabolism. It is unlikely that daptomycin will inhibit or induce the metabolism of medicinal products metabolised by the P450 system.

Interaction studies for daptomycin were performed with aztreonam, tobramycin, warfarin and probenecid. Daptomycin had no effect on the pharmacokinetics of warfarin or probenecid, nor did these medicinal products alter the pharmacokinetics of daptomycin. The pharmacokinetics of daptomycin were not significantly altered by aztreonam.

Although small changes in the pharmacokinetics of daptomycin and tobramycin were observed during coadministration by intravenous infusion over a 30-minute period using a daptomycin dose of 2 mg/kg, the changes were not statistically significant. The interaction between daptomycin and tobramycin with an approved dose of daptomycin is unknown. Caution is warranted when daptomycin is co-administered with tobramycin.

Experience with the concomitant administration of daptomycin and warfarin is limited. Studies of daptomycin with anticoagulants other than warfarin have not been conducted. Anticoagulant activity in patients receiving daptomycin and warfarin should be monitored for the first several days after therapy with daptomycin is initiated.

There is limited experience regarding concomitant administration of daptomycin with other medicinal products that may trigger myopathy (e.g. HMG-CoA reductase inhibitors). However, some cases of marked rises in CPK levels and cases of rhabdomyolysis occurred in adult patients taking one of these medicinal products at the same time as daptomycin. It is recommended that other medicinal products associated with myopathy should if possible be temporarily discontinued during treatment with daptomycin unless the benefits of concomitant administration outweigh the risk. If co-administration cannot be avoided, CPK levels should be measured more frequently than once weekly and patients should be closely monitored for any signs or symptoms that might represent myopathy. See sections 4.4, 4.8 and 5.3.

Daptomycin is primarily cleared by renal filtration and so plasma levels may be increased during co-administration with medicinal products that reduce renal filtration (e.g. NSAIDs and COX-2 inhibitors). In addition, there is a potential for a pharmacodynamic interaction to occur during co- administration due to additive renal effects. Therefore, caution is advised when daptomycin is co- administered with any other medicinal product known to reduce renal filtration.

During post–marketing surveillance, cases of interference between daptomycin and particular reagents used in some assays of prothrombin time/international normalised ratio (PT/INR) have been reported. This interference led to a false prolongation of PT and elevation of INR. If unexplained abnormalities of PT/INR are observed in patients taking daptomycin, consideration should be given to a possible in vitro interaction with the laboratory test. The possibility of erroneous results may be minimised by drawing samples for PT or INR testing near the time of trough plasma concentrations of daptomycin (see section 4.4).

4.6. Fertility, pregnancy and lactation

Pregnancy

No clinical data on pregnancies are available for daptomycin. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3).

Daptomycin should not be used during pregnancy unless clearly necessary i.e., only if the expected benefit outweighs the possible risk.

Breast-feeding

In a single human case study, daptomycin was intravenously administered daily for 28 days to a nursing mother at a dose of 500 mg/day, and samples of the patient's breast milk were collected over a 24-hour period on day 27. The highest measured concentration of daptomycin in the breast milk was 0.045 mcg/ml, which is a low concentration. Therefore, until more experience is gained, breast- feeding should be discontinued when daptomycin is administered to nursing women.

Fertility

No clinical data on fertility are available for daptomycin. Animal studies do not indicate direct or indirect harmful effects with respect to fertility (see section 5.3).

4.7. Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed.

On the basis of reported adverse drug reactions, daptomycin is presumed to be unlikely to produce an effect on the ability to drive or use machinery.

4.8. Undesirable effects

Summary of the safety profile

In clinical studies, 2,011 adult subjects received daptomycin. Within these trials, 1,221 subjects received a daily dose of 4 mg/kg, of whom 1,108 were patients and 113 were healthy volunteers; 460 subjects received a daily dose of 6 mg/kg, of whom 304 were patients and 156 were healthy volunteers. In paediatric studies, 372 patients received daptomycin, of whom 61 received a single dose and 311 received a therapeutic regimen for cSSTI or SAB (daily doses ranged from 4 mg/kg to 12 mg/kg). Adverse reactions (i.e. considered by the investigator to be possibly, probably, or definitely related to the medicinal product) were reported at similar frequencies for daptomycin and comparator regimens.

The most frequently reported adverse reactions (frequency common (≥ 1/100 to < 1/10)) are: Fungal infections, urinary tract infection, candida infection, anaemia, anxiety, insomnia, dizziness, headache, hypertension, hypotension, gastrointestinal and abdominal pain, nausea, vomiting, constipation, diarrhoea, flatulence, bloating and distension, liver function tests abnormal (increased alanine aminotransferase (ALT), aspartate aminotransferase (AST) or alkaline phosphatase (ALP)), rash, pruritus, limb pain, serum creatine phosphokinase (CPK) increased, infusion site reactions, pyrexia, asthenia.

Less frequently reported, but more serious, adverse reactions include hypersensitivity reactions, eosinophilic pneumonia (occasionally presenting as organising pneumonia), drug reaction with eosinophilia and systemic symptoms (DRESS), angioedema and rhabdomyolysis.

Tabulated list of adverse reactions

The following adverse reactions were reported during therapy and during follow-up with frequencies corresponding to very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); not known (cannot be estimated from the available data):

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

1 While the exact incidence of eosinophilic pneumonia associated with daptomycin is unknown, to date the reporting rate of spontaneous reports is very low (<1/10,000).

2 In some cases of myopathy involving raised CPK and muscle symptoms, the patients also presented with elevated transaminases. These transaminase increases were likely to be related to the skeletal muscle effects. The majority of transaminase elevations were of Grade 1-3 toxicity and resolved upon discontinuation of treatment.

3 When clinical information on the patients was available to make a judgement, approximately 50% of the cases occurred in patients with pre-existing renal impairment, or in those receiving concomitant medicinal products known to cause rhabdomyolysis.

The safety data for the administration of daptomycin via 2-minute intravenous injection are derived from two pharmacokinetic studies in healthy adult volunteers. Based on these study results, both methods of daptomycin administration, the 2-minute intravenous injection and the 30-minute intravenous infusion, had a similar safety and tolerability profile. There was no relevant difference in local tolerability or in the nature and frequency of adverse reactions.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions the Yellow Card Scheme, website www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9. Overdose

In the event of overdose, supportive care is advised. Daptomycin is slowly cleared from the body by haemodialysis (approximately 15% of the administered dose is removed over 4 hours) or by peritoneal dialysis (approximately 11% of the administered dose is removed over 48 hours).
