4 CLINICAL PARTICULARS
4.1 Therapeutic indications
In combination with other immunosuppressant substances for the prevention of acute and chronic transplant rejection following allogenic transplantation of kidneys, liver, heart, heart-lung, lung or pancreas.
Treatment of transplant rejection in patients who have previously received other immunosuppressants.
Prevention and treatment of graft-versus-host-disease (GVHD) following allogenic bone marrow transplantation.
Treatment of severe forms of psoriasis, particularly of the plaque type, which are not sufficiently treatable with conventional systemic therapy.
Treatment of severe atopic dermatitis in patients in whom conventional therapy is inappropriate or ineffective.
Treatment of steroid-dependent and steroid-resistant nephrotic syndrome due to glomerular disorders such as glomerular minimum changes, focal segmental glomerulosclerosis or membranous glomerulonephritis in adults and children whose glucocorticoids or alkylating agents are either insufficiently effective or involve unacceptable risks.
Munidex can be administered to achieve remission or maintenance of this condition. It can also be used to maintain steroid-induced remission and thus allow for reduction of corticosteroids.
Treatment of severe, active rheumatoid arthritis in adults when conventional therapy, including at least one highly effective disease modifying antirheumatic medicinal product (DMARD) (e.g. low-dose methotrexate), has proved inadequate.
4.2 Posology and method of administration
Posology
The dose ranges given for oral administration are intended to serve as guidelines only.
The daily doses of Munidex should be given in two divided doses equally distributed throughout the day. It is recommended that Munidex be administered on a consistent schedule with regard to time of day.
Munidex should only be prescribed by, or in close collaboration with, a physician with experience of immunosuppressive therapy and/or organ transplantation.
Transplantation
Organ transplantation
Treatment with Munidex should be initiated within 12 hours before surgery with a dose of 10 to 15 mg/kg given in 2 divided doses. This dose should be maintained as the daily dose for 1to 2 weeks post-operatively, being gradually reduced in accordance with blood levels according to local immunosuppressive protocols until a recommended maintenance dose of about 2 to 6 mg/kg given in 2 divided doses is reached.
When Munidex is given with other immunosuppressants (e.g. with corticosteroids or as part of a triple or quadruple medicinal product therapy), lower doses (e.g. 3to 6 mg/kg given in 2 divided doses for the initial treatment) may be used.
Bone marrow transplantation
The initial dose should be given on the day before transplantation. In most cases, ciclosporin concentrate for solution for infusion is preferred for this purpose. The recommended intravenous dose is 3 to 5 mg/kg/day. Infusion is continued at this dose level during the immediate post-transplant period of up to 2 weeks, before a change is made to oral maintenance therapy with Munidex at daily doses of about 12.5 mg/kg given in 2 divided doses.
Maintenance treatment should be continued for at least 3 months (and preferably for 6 months) before the dose is gradually decreased to zero by 1 year after transplantation.
If Munidex is used to initiate therapy, the recommended daily dose is 12.5 to 15mg/kg, given in 2 divided doses, starting on the day before transplantation.
Higher doses of Munidex, or the use of ciclosporin intravenous therapy, may be necessary in the presence of gastrointestinal disturbances which might decrease absorption.
In some patients, GVHD occurs after discontinuation of ciclosporin treatment, but usually responds favourably to re-introduction of therapy. In such cases an initial oral loading dose of 10 to 12.5 mg/kg should be given, followed by daily oral administration of the maintenance dose previously found to be satisfactory. Low doses of Munidex should be used for mild, chronic GVHD.
Non-transplantation indications
When using Munidex in any of the established non-transplantation indications, the following general rules should be adhered to:
Before initiation of treatment a reliable baseline level of renal function should be established by at least two measurements. The estimated glomerular filtration rate (eGFR) by the MDRD formula can be used for estimation of renal function in adults and an appropriate formula should be used to assess eGFR in paediatric patients.
Since Munidex can impair renal function, it is necessary to assess renal function frequently. If eGFR decreases by more than 25% below baseline at more than one measurement, the dosage Munidex should be reduced by 25 to 50%. If the eGFR decrease from baseline exceeds 35%, further reduction of the dose of Munidex should be considered. These recommendations apply even if the patient's values still lie within the laboratory's normal range. If dose reduction is not successful in improving eGFR within one month, Munidex treatment should be discontinued (see section 4.4).
Regular monitoring of blood pressure is required.
The determination of bilirubin and parameters that assess hepatic function are required prior to starting therapy and close monitoring during treatment is recommended. Determinations of serum lipids, potassium, magnesium and uric acid are advisable before treatment and periodically during treatment.
Occasional monitoring of ciclosporin blood levels may be relevant in non-transplant indications, e.g. when Munidex is co-administered with substances that may interfere with the pharmacokinetics of ciclosporin, or in the event of unusual clinical response (e.g. lack of efficacy or increased drug intolerance such as renal dysfunction).
The normal route of administration is by mouth. If the concentrate for solution for infusion is used, careful consideration should be given to administering an adequate intravenous dose that corresponds to the oral dose. Consultation with a physician with experience of use of ciclosporin is recommended.
Except in children with nephrotic syndrome, the total daily dose must never exceed 5 mg/kg.
For maintenance treatment the lowest effective and well tolerated dosage should be determined individually.
In patients in whom within a given time (for specific information see below) no adequate response is achieved or the effective dose is not compatible with the established safety guidelines, treatment with Munidex should be discontinued.
Nephrotic syndrome:
For inducing remission the recommended daily dose is given in 2 divided oral doses.
If the renal function (except for proteinuria) is normal, the recommended daily dose is the following:
- adults: 5 mg/kg
- children: 6 mg/kg
In patients with impaired renal function, the initial dose should not exceed 2.5 mg/kg/day.
The combination of Munidex with low doses of oral corticosteroids is recommended if the effect of Munidex alone is not satisfactory, especially in steroid-resistant patients.
Time to improvement varies from 3 to 6 months depending on the type of glomerulopathy. If no improvement has been observed after this time to improvement period, Munidex therapy should be discontinued.
The doses need to be adjusted individually according to efficacy (proteinuria) and safety, but should not exceed 5 mg/kg/day in adults and 6 mg/kg/day in children.
For maintenance treatment the dose should be slowly reduced to the lowest effective level.
Rheumatoid arthritis:
For the first 6 weeks of treatment, the recommended dose is 3 mg/kg/day orally, given in 2 divided doses. If the effect is insufficient, the daily dose may then be increased gradually, as tolerability permits, but should not exceed 5 mg/kg . To achieve full effectiveness, up to 12 weeks of Munidex therapy may be required.
For maintenance treatment the dose has to be titrated individually to the lowest effective level according to tolerability.
Munidex can be given in combination with low-dose corticosteroids and/or nonsteroidal anti-inflammatory drugs (NSAIDs) (see section 4.4). Munidex can also be combined with low-dose weekly methotrexate in patients who have insufficient response to methotrexate alone, by using 2.5 mg/kg Munidex in 2 divided doses per day initially, with the option to increase the dose as tolerability permits.
Psoriasis:
Munidex treatment should be initiated by physicians with experience in the diagnosis and treatment of psoriasis. Due to the variability of this condition, treatment must be individualised. For inducing remission, the recommended initial dose is 2.5 mg/kg/day orally given in 2 divided doses. If there is no improvement after 1 month, the daily dose may be gradually increased, but should not exceed 5 mg/kg. Treatment should be discontinued in patients in whom sufficient response of psoriatic lesions cannot be achieved within 6 weeks on 5 mg/kg/day, or in whom the effective dose is not compatible with the established safety guidelines (see section 4.4).
Initial doses of 5 mg/kg/day are justified in patients whose condition requires rapid improvement. Once satisfactory response is achieved, Munidex may be discontinued and subsequent relapse managed with re-introduction of Munidex at the previous effective dose. In some patients,continuous maintenance therapy may be necessary.
For maintenance treatment, doses have to be individually titrated to the lowest effective level, and the dose should not exceed 5 mg/kg/day.
Atopic dermatitis:
Munidex treatment should be initiated by physicians with experience in the diagnosis and treatment of atopic dermatitis. Due to the variability of this condition, treatment must be individualised. The recommended dose range is 2.5 to 5 mg/kg/day given in 2 divided oral doses. If a starting dose of 2.5 mg/kg/day does not achieve a satisfactory response within 2 weeks, the daily dose may be rapidly increased to a maximum of 5 mg/kg. In very severe cases, rapid and adequate control of the disease is more likely to occur with a starting dose of 5 mg/kg/day. Once satisfactory response is achieved, the dose should be reduced gradually and, if possible, Munidex should be discontinued. Subsequent relapse may be managed with a further course of Munidex.
Although an 8-week course of therapy may be sufficient to achieve clearing, up to 1 year of therapy has been shown to be effective and well tolerated, provided the monitoring guidelines are followed.
Switching between oral ciclosporin_ formulation
The switch from one oral ciclosporin formulation to another should be made under physician supervision, including monitoring of blood levels of ciclosporin for transplantation patients.
Special populations Patients with renal impairment All indications
Ciclosporin undergoes minimal renal elimination and its pharmacokinetics are not extensively affected by renal impairment (see section 5.2). However, due to its nephrotoxic potential (see section 4.8), careful monitoring of renal function is recommended (see section 4.4).
Non-transplantation indications
With the exception of patients being treated for nephrotic syndrome, patients with impaired renal function should not receive Munidex (see subsection on additional precautions in non-transplantation indications in section 4.4). In nephrotic syndrome patients with impaired renal function, the initial dose should not exceed 2.5 mg/kg/day.
Patients with hepatic impairment
Ciclosporin is extensively metabolised by the liver. An approximate 2- to 3-fold increase in ciclosporin exposure may be observed in patients with hepatic impairment.
Dose reduction may be necessary in patients with severe liver impairment to maintain blood levels within the recommended target range (see sections 4.4 and 5.2) and it is recommended that ciclosporin blood levels are monitored until stable levels are reached.
Paediatric population
Clinical studies have included children from 1 year of age. In several studies, paediatric patients required and tolerated higher doses of ciclosporin per kg body weight than those used in adults.
Use of Munidex in children for non-transplantation indications other than nephrotic syndrome cannot be recommended (see section 4.4).
Elderly population (age 65 years and above)
Experience with Munidex in the elderly is limited.
In rheumatoid arthritis clinical trials with ciclosporin, patients aged 65 or older were more likely to develop systolic hypertension on therapy, and more likely to show serum creatinine rises >50% above the baseline after 3 to 4 months of therapy.
Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or medication and increased susceptibility for infections.
Method of administration Oral use
Munidex capsules can be taken with or without food and should be taken with a mouthful of water and should be swallowed whole.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Combination with products containing Hypericum perforatum (St John's Wort) (see section 4.5).
Combination with medicines that are substrates for the multidrug efflux transporter P-glycoprotein or the organic anion transporter proteins (OATP) and for which elevated plasma concentrations are associated with serious and/or life-threatening events, e.g. bosentan, dabigatran etexilate and aliskiren (see section 4.5).
4.4 Special warnings and precautions for use
Medical supervision
Munidex should be prescribed only by physicians who are experienced in immunosuppressive therapy, and can provide adequate follow-up, including regular full physical examination, measurement of blood pressure, and control of laboratory safety parameters. Transplantation patients receiving this medicinal product should be managed in facilities with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should receive complete information for the follow-up of the patient.
Lymphomas and other malignancies
Like other immunosuppressants, ciclosporin increases the risk of developing lymphomas and other
malignancies, particularly those of the skin. The increased risk appears to be related to the degree and duration of immunosuppression rather than to the use of specific agents.
A treatment regimen containing multiple immunosuppressants (including ciclosporin) should therefore be used with caution as this could lead to lymphoproliferative disorders and solid organ tumours, some with reported fatalities.
In view of the potential risk of skin malignancy, patients on Munidex, in particular those treated for psoriasis or atopic dermatitis, should be warned to avoid excess unprotected sun exposure and should not receive concomitant ultraviolet B irradiation or PUVA photochemotherapy.
Infections
Like other immunosuppressants, ciclosporin predisposes patients to the development of a variety of bacterial, fungal, parasitic and viral infections, often with opportunistic pathogens.
Activation of latent polyomavirus infections that may lead to polyomavirus associated nephropathy (PVAN), especially to BK virus nephropathy (BKVN), or to JC virus associated progressive multifocal leukoencephalopathy (PML), have been observed in patients receiving ciclosporin. These conditions are often related to a high total immunosuppressive burden and should be considered in the differential diagnosis in immunosuppressed patients with deteriorating renal function or neurological symptoms. Serious and/or fatal outcomes have been reported. Effective pre-emptive and therapeutic strategies should be employed particularly in patients on multiple long-term immunosuppressive therapy.
Renal toxicity
A frequent and potentially serious complication, an increase in serum creatinine and urea, may occur during Munidex therapy. These functional changes are dose-dependent and are initially reversible, usually responding to dose reduction. During long-term treatment, some patients may develop structural changes in the kidney (e.g. interstitial fibrosis) which, in renal transplant patients, must be differentiated from changes due to chronic rejection. Frequent monitoring of renal function is therefore required according to local guidelines for the indication in question (see sections 4.2 and 4.8).
Hepatotoxicity
Munidex may also cause dose-dependent, reversible increases in serum bilirubin and in liver enzymes (see section 4.8).There have been solicited and spontaneous reports of hepatotoxicity and liver injury including cholestasis, jaundice, hepatitis and liver failure in patients treated with ciclosporin. Most reports included patients with significant co-morbidities, underlying conditions and other confounding factors including infectious complications and co-medications with hepatotoxic potential. In some cases, mainly in transplant patients, fatal outcomes have been reported (see section 4.8). Close monitoring of the parameters that assess hepatic function is required and abnormal values may necessitate dose reduction (see sections 4.2 and 5.2).
Elderly population (age 65 years and above)
In elderly patients, the renal function should be monitored with particular care. Monitoring ciclosporin levels (see section 4.2)
When Munidex is used in transplant patients, routine monitoring of ciclosporin blood levels is an important safety measure. For monitoring ciclosporin levels in whole blood, a specific monoclonal antibody (measurement of parent compound) is preferred; a high-performance liquid chromatography (HPLC) method, which also measures the parent compound, can be used as well. If plasma or serum is used, a standard separation protocol (time and temperature) should be followed.
For the initial monitoring of liver transplant patients, either the specific monoclonal antibody should be used, or parallel measurements using both the specific monoclonal antibody and the non-specific monoclonal antibody should be performed, to ensure a dosage that provides adequate immunosuppression.
In non-transplant patients, occasional monitoring of ciclosporin blood levels is recommended, e.g. when Munidex is co-administered with substances that may interfere with the pharmacokinetics of ciclosporin, or in the event of unusual clinical response (e.g. lack of efficacy or increased drug intolerance such as renal dysfunction).
It must be remembered that the ciclosporin concentration in blood, plasma, or serum is only one of many factors contributing to the clinical status of the patient. Results should therefore serve only as a guide to dosage in relationship to other clinical and laboratory parameters.
Hypertension
Regular monitoring of blood pressure is required during Munidex therapy. If hypertension develops, appropriate antihypertensive treatment must be instituted. Preference should be given to an antihypertensive agent that does not interfere with the pharmacokinetics of ciclosporin, e.g. isradipine (see section 4.5).
Blood lipids increased
Since ciclosporin has been reported to induce a reversible slight increase in blood lipids, it is advisable to perform lipid determinations before treatment and after the first month of therapy. In the event of increased lipids being found, restriction of dietary fat and, if appropriate, a dose reduction, should be considered.
Hyperkalaemia
Ciclosporin enhances the risk of hyperkalaemia, especially in patients with renal dysfunction. Caution is also required when ciclosporin is co-administered with potassium-sparing drugs (e.g. potassium-sparing diuretics, angiotensin converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists) or potassium-containing medicinal products as well as in patients on a potassium rich diet. Control of potassium levels in these situations is advisable.
Hypomagnesaemia
Ciclosporin enhances the clearance of magnesium. This can lead to symptomatic hypomagnesaemia, especially in the peri-transplant period. Control of serum magnesium levels is therefore recommended in the peri-transplant period, particularly in the presence of neurological symptom/signs. If considered necessary, magnesium supplementation should be given.
Hyperuricaemia
Caution is required when treating patients with hyperuricaemia.
Live-attenuated vaccines
During treatment with ciclosporin, vaccination may be less effective. The use of live attenuated vaccines should be avoided (see section 4.5).
Interactions
Caution should be observed when co-administering ciclosporin with drugs that substantially increase or decrease ciclosporin plasma concentrations, through inhibition or induction of CYP3A4 and/or P-glycoprotein (see section 4.5).
Renal toxicity should be monitored when initiating ciclosporin use together with active substances that increase ciclosporin levels or with substances that exhibit nephrotoxic synergy (see section 4.5).
Concomitant use of ciclosporin and tacrolimus should be avoided (see section 4.5).
Ciclosporin is an inhibitor of CYP3A4, the multidrug efflux transporter P-glycoprotein and organic anion transporter proteins (OATP) and may increase plasma levels of co-medications that are substrates of this enzyme and/or transporter. Caution should be observed while co-administering ciclosporin with such drugs or concomitant use should be avoided (see section 4.5). Ciclosporin increases the exposure to HMG-CoA reductase inhibitors (statins). When concurrently administered with ciclosporin, the dosage of the statins should be reduced and concomitant use of certain statins should be avoided according to their label recommendations. Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis (see section 4.5).
Following concomitant administration of ciclosporin and lercanidipine, the AUC of lercanidipine was increased three-fold and the AUC of ciclosporin was increased 21%. Therefore the simultaneous combination of ciclosporin and lercanidipine should be avoided. Administration of ciclosporin 3 hours after lercanidipine yielded no change of the lercanidipine AUC, but the ciclosporin AUC was increased by 27%.
This combination should therefore be given with caution with an interval of at least 3 hours.
Special excipients: Macrogolglycerol hydroxystearate
Munidex contains Macrogolglycerol hydroxystearate, which may cause stomach upsets and diarrhoea.
Special excipients: ethyl lactate
Munidex contains ethyl lactate which is hydrolysed to ethanol and lactic acid in the gastrointestinal tract.
Munidex 25 mg soft capsules hydrolyse to 32 mg pure ethanol.
Munidex 50 mg soft capsules hydrolyse to 65 mg pure ethanol.
Munidex 100 mg soft capsules hydrolyse to 129 mg pure ethanol.
I.e. up to 679.8 mg per dose (maximum dose), equivalent to approximately 15 ml of beer, or approximately 6 ml of wine.
This may be harmful in alcoholic patients and should be taken into account in pregnant or breast-feeding women, in patients presenting with liver disease or epilepsy, or if the patients is a child.
Special excipients: Lecithin (soya)
See section 4.3.
Additional precautions in non-transplant indications
Patients with impaired renal function (except in nephrotic syndrome patients with a permissible degree of renal impairment), uncontrolled hypertension, uncontrolled infections, or any kind of malignancy should not receive ciclosporin.
Before initiation of treatment a reliable baseline assessment of renal function should be established by at least two measurements of eGFR. Renal function must be assessed frequently throughout therapy to allow dosage adjustment (see section 4.2).
Additional precautions in nephrotic syndrome
Patients with abnormal baseline renal function should initially be treated with 2.5 mg/kg/day and must be monitored very carefully.
In some patients, it may be difficult to detect Munidex-induced renal dysfunction because of changes in renal function related to the nephrotic syndrome itself. This explains why, in rare cases, ciclosporin-associated structural kidney alterations have been observed without increases in serum creatinine. Renal biopsy should be considered for patients with steroid-dependent minimal-change nephropathy, in whom Munidex therapy has been maintained for more than 1 year.
In patients with nephrotic syndrome treated with immunosuppressants (including ciclosporin), the occurrence of malignancies (including Hodgkin’s lymphoma) has occasionally been reported.
Additional precautions in rheumatoid arthritis
After 6 months of therapy, renal function needs to be assessed every 4-8 weeks depending on the stability of the disease, its co-medication, and concomitant diseases. More frequent checks are necessary when the Munidex dose is increased, or concomitant treatment with an NSAID is initiated or its dosage increased. Discontinuation of Munidex may also become necessary if hypertension developing during treatment cannot be controlled by appropriate therapy.
As with other long-term immunosuppressive treatments, an increased risk of lymphoproliferative disorders must be borne in mind. Special caution should be observed if Munidex is used in combination with methotrexate due to nephrotoxic synergy.
Additional precautions in psoriasis
Discontinuation of Munidex therapy is recommended if hypertension developing during treatment cannot be controlled with appropriate therapy.
Elderly patients should be treated only in the presence of disabling psoriasis, and renal function should be monitored with particular care.
There is only limited experience with the use of Munidex in children with psoriasis.
In psoriatic patients on ciclosporin, as in those on conventional immunosuppressive therapy, development of malignancies (in particular of the skin) has been reported. Skin lesions not typical for psoriasis, but suspected to be malignant or pre-malignant should be biopsied before Munidex treatment is started. Patients with malignant or pre-malignant alterations of the skin should be treated with Munidex only after appropriate treatment of such lesions, and if no other option for successful therapy exists.
In a few psoriatic patients treated with ciclosporin, lymphoproliferative disorders have occurred. These were responsive to prompt discontinuation.
Patients on Munidex should not receive concomitant ultraviolet B irradiation or PUVA photochemotherapy.
Additional precautions in atopic dermatitis
Discontinuation of Munidex is recommended if hypertension developing during treatment cannot be controlled with appropriate therapy.
Experience with Munidex in children with atopic dermatitis is limited.
Elderly patients should be treated only in the presence of disabling atopic dermatitis and renal function should be monitored with particular care.
Benign lymphadenopathy is commonly associated with flares in atopic dermatitis and invariably disappears spontaneously or with general improvement in the disease.
Lymphadenopathy observed on treatment with ciclosporin should be regularly monitored.
Lymphadenopathy which persists despite improvement in disease activity should be examined by biopsy as a precautionary measure to ensure the absence of lymphoma.
Active herpes simplex infections should be allowed to clear before treatment with Munidex is initiated, but are not necessarily a reason for treatment withdrawal if they occur during therapy unless infection is severe.
Skin infections with Staphylococcus aureus are not an absolute contraindication for Munidex therapy, but should be controlled with appropriate antibacterial agents. Oral erythromycin which is known to have the potential to increase the blood concentration of ciclosporin (see section 4.5) should be avoided. If there is no alternative, it is recommended to closely monitor blood levels of ciclosporin, renal function, and for side effects of ciclosporin.
Patients on Munidex should not receive concomitant ultraviolet B irradiation or PUVA photochemotherapy.
Paediatric use in non-transplantation indications
Except for the treatment of nephrotic syndrome, there is no adequate experience available with Munidex; its use in children under 16 years of age for non-transplant indications other than nephrotic syndrome cannot be recommended.
4.5 Interaction with other medicinal products and other forms of interaction
Drug interactions
Of the many drugs reported to interact with ciclosporin, those for which the interactions are adequately substantiated and considered to have clinical implications are listed below.
Various agents are known to either increase or decrease plasma or whole blood ciclosporin levels usually by inhibition or induction of enzymes involved in the metabolism of ciclosporin, in particular CYP3A4.
Ciclosporin is also an inhibitor of CYP3A4, the multidrug efflux transporter P-glycoprotein and organic anion transporter proteins (OATP) and may increase plasma levels of co-medications that are substrates of this enzyme and/or transporters.
Medicinal products known to reduce or increase the bioavailability of ciclosporin: In transplant patients frequent measurement of ciclosporin levels and, if necessary, ciclosporin dosage adjustment is required, particularly during the introduction or withdrawal of the co-administered medication. In non-transplant patients the relationship between blood level and clinical effects is less well established. If medicinal products known to increase ciclosporin levels are given concomitantly, frequent assessment of renal function and careful monitoring for ciclosporin-related side effects may be more appropriate than blood level measurement.
Drugs that decrease ciclosporin levels
All inducers of CYP3A4 and/or P-glycoprotein are expected to decrease ciclosporin levels. Examples of drugs that decrease ciclosporin levels are:
Barbiturates, carbamazepine, oxcarbazepine, phenytoin; nafcillin, intravenous sulfadimidine, probucol, orlistat, hypericum perforatum (St. John’s wort), ticlopidine, sulfinpyrazone, terbinafine, bosentan.
Products containing Hypericum perforatum (St John s Wort) must not be used concomitantly with Munidex due to the risk of decreased blood levels of ciclosporin and thereby reduced effect (see section 4.3).
Rifampicin induces ciclosporin intestinal and liver metabolism. Ciclosporin doses may need to be increased 3- to 5-fold during co-administration.
Octreotide decreases oral absorption of ciclosporin and a 50% increase in the ciclosporin dose or a switch to intravenous administration could be necessary.
Drugs that increase ciclosporin levels
All inhibitors of CYP3A4 and/or P-glycoprotein may lead to increased levels of cyclosporine. Examples are:
Nicardipine, metoclopramide, oral contraceptives, methylprednisolone (high dose), allopurinol, cholic acid and derivatives, protease inhibitors, imatinib, colchicine, nefazodone.
Macrolide antibiotics: Erythromycin can increase ciclosporin exposure 4- to 7-fold, sometimes resulting in nephrotoxicity. Clarithromycin has been reported to double the exposure of ciclosporin. Azitromycin increases ciclosporin levels by around 20%.
Azole antibiotics: Ketoconazole, fluconazole, itraconazole and voriconazole could more than double ciclosporin exposure.
Verapamil increases ciclosporin blood concentrations 2- to 3-fold.
Co-administration with telaprevir resulted in approximately 4.64-fold increase in ciclosporin dose normalised exposure (AUC).
Amiodarone substantially increases the plasma ciclosporin concentration concurrently with an increase in serum creatinine. This interaction can occur for a long time after withdrawal of amiodarone, due to its very long half-life (about 50 days).
Danazol has been reported to increase ciclosporin blood concentrations by approximately 50%.
Diltiazem (at doses of 90 mg/day) can increase ciclosporin plasma concentrations by up to 50%
Imatinib could increase ciclosporin exposure and C by around 20%.
Food interactions
The concomitant intake of grapefruit and grapefruit juice has been reported to increase the bioavailability of ciclosporin.
Combinations with increased risk_ for nephrotoxicity
Care should be taken when using ciclosporin together with other active substances that exhibit nephrotoxic synergy such as: aminoglycosides (including gentamycin, tobramycin), amphotericin B, ciprofloxacin, vancomycin, trimethoprim (+ sulfamethoxazole); fibric acid derivatives (e.g. bezafibrate, fenofibrate); NSAIDs (including diclofenac, naproxen, sulindac); melphalan histamine H2-receptor antagonists (e.g. cimetidine, ranitidine); methotrexate (see section 4.4).
During the concomitant use of a drug that may exhibit nephrotoxic synergy, close monitoring of renal function should be performed. If a significant impairment of renal function occurs, the dosage of the co-administered medicinal product should be reduced or alternative treatment considered.
Concomitant use of ciclosporin and tacrolimus should be avoided due to the risk for nephrotoxicity and pharmacokinetic interaction via CYP3A4 and/or P-gp (see section 4.4).
Effects of ciclosporin on other drugs
Ciclosporin is an inhibitor of CYP3A4, the multidrug efflux transporter P-glycoprotein (P-gp) and organic anion transporter proteins (OATP). Co-administration of drugs that are substrates of CYP3A4, P-gp and OATP with ciclosporin may increase plasma levels of co-medications that are substrates of this enzyme and/or transporter.
Some examples are listed below:
Ciclosporin may reduce the clearance of digoxin, colchicine, HMG-CoA reductase inhibitors (statins) and etoposide. If any of these drugs are used concurrently with ciclosporin, close clinical observation is required in order to enable early detection of toxic manifestations of the medicinal products, followed by reduction of its dosage or its withdrawal. When concurrently administered with ciclosporin, the dosage of the statins should be reduced and concomitant use of certain statins should be avoided according to their label recommendations. Exposure changes of commonly used statins with ciclosporin are summarised in Table 1. Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis.

Caution is recommended when co-administering ciclosporin with lercanidipine (see section 4.4).
Following concomitant administration of ciclosporin and aliskiren, a P-gp substrate, the Cmax of aliskiren was increased approximately 2.5-fold and the AUC approximately 5-fold. However, the pharmacokinetic profile of ciclosporin was not significantly altered. Co-administration of ciclosporin and aliskiren is not recommended (see section 4.3).
Concomitant administration of dabigatran etexilate is not recommended due to the Pgp inhibitory activity of ciclosporin (see section 4.3).
The concurrent administration of nifedipine with ciclosporin may result in an increased rate of gingival hyperplasia compared with that observed when ciclosporin is given alone.
The concomitant use of diclofenac and ciclosporin has been found to result in a significant increase in the bioavailability of diclofenac, with the possible consequence of reversible renal function impairment. The increase in the bioavailability of diclofenac is most probably caused by a reduction of its high first-pass effect. If NSAIDs with a low first-pass effect (e.g. acetylsalicylic acid) are given together with ciclosporin, no increase in their bioavailability is to be expected.
Elevations in serum creatinine were observed in the studies using everolimus or sirolimus in combination with full-dose ciclosporin for microemulsion. This effect is often reversible with ciclosporin dose reduction. Everolimus and sirolimus had only a minor influence on ciclosporin pharmacokinetics. Co-administration of ciclosporin significantly increases blood levels of everolimus and sirolimus.
Caution is required with concomitant use of potassium-sparing medicinal products (e.g. potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists) or potassium-containing medicinal products since they may lead to significant increases in serum potassium (see section 4.4).
Ciclosporin may increase the plasma concentrations of repaglinide and thereby increase the risk of hypoglycaemia.
Co-administration of bosentan and ciclosporin in healthy volunteers increases the bosentan exposure several-fold and there was a 35% decrease in ciclosporin exposure. Co-administration of ciclosporin with bosentan is not recommended (see above subsection “Drugs that decrease ciclosporin levels” and section 4.3).
Multiple dose administration of ambrisentan and ciclosporin in healthy volunteers resulted in an approximately 2-fold increase in ambrisentan exposure, while the ciclosporin exposure was marginally increased (approximately 10%).
A significantly increased exposure to anthracycline antibiotics (e.g. doxorubicine, mitoxanthrone, daunorubicine) was observed in oncology patients with the intravenous co-administration of anthracycline antibiotics and very high doses of ciclosporin.
During treatment with ciclosporin, vaccination may be less effective and the use of live attenuated vaccines should be avoided.
Paediatric population
Interaction studies have only been performed in adults.
4.6 Fertility, pregnancy and lactation
Pregnancy
Animal studies have shown reproductive toxicity in rats and rabbits.
Experience with Munidex in pregnant women is limited. Pregnant women receiving immunosuppressive therapies after transplantation, including ciclosporin and ciclosporin-containing regimens, are at risk of premature delivery (<37 weeks).
A limited number of observations in children exposed to ciclosporin in utero are available, up to an age of approximately 7 years. Renal function and blood pressure in these children were normal.
However, there are no adequate and well-controlled studies in pregnant women and therefore Munidex should not be used during pregnancy unless the potential benefit to the mother justifies the potential risk to the foetus. The ethanol from the ethyl lactate content of the Munidex formulations should also be taken into account in pregnant women (see section 4.4).
Breast-feeding
Ciclosporin passes into breast milk. The excipient ethyl lactate is hydrolysed to ethanol (see section 4.4). The ethanol content of the Munidex formulations should also be taken into account in women who are breast-feeding (see section 4.4). Mothers receiving treatment with Munidex should not breast-feed because of the potential of Munidex to cause serious adverse drug reactions in breast-fed newborns/infants. A decision should be made whether to abstain from breast-feeding or to abstain from using the medicinal drug, taking into account the importance of the medicinal product to the mother.
Fertility
There is limited data on the effect of Munidex on human fertility (see section 5.3).
4.7 Effects on ability to drive and use machines
No data exist on the effects of Munidex on ability to drive and use machines.
The excipient ethyl lactate is hydrolysed to ethanol (see section 4.4). Ethanol may have an influence on the ability to drive and use machines.
4.8 Undesirable effects
Summary of the safety profile
The principal adverse reactions observed in clinical trials and associated with the administration of ciclosporin include renal dysfunction, tremor, hirsutism, hypertension, diarrhoea, anorexia, nausea and vomiting.
Many side effects associated with ciclosporin therapy are dose-dependent and responsive to dose reduction.
In the various indications the overall spectrum of side effects is essentially the same; there are, however, differences in incidence and severity. As a consequence of the higher initial doses and longer maintenance therapy required after transplantation, side effects are more frequent and usually more severe in transplant patients than in patients treated for other indications.
Anaphylactoid reactions have been observed following intravenous administration (see section 4.4).
Infections and Infestations
Patients receiving immunosuppressive therapies, including ciclosporin and ciclosporin containing regimens, are at increased risk of infections (viral, bacterial, fungal, parasitic) (see section 4.4). Both generalised and localised infections can occur. Preexisting infections may also be aggravated and reactivation of polyomavirus infections may lead to polyomavirus associated nephropathy (PVAN) or to JC virus associated progressive multifocal leukopathy (PML). Serious and/or fatal outcomes have been reported.
Neoplasms benign, malignant and unspecified (including cysts and polyps)
Patients receiving immunosuppressive therapies, including ciclosporin and ciclosporin containing regimens, are at increased risk of developing lymphomas or lymphoproliferative disorders and other malignancies, particularly of the skin. The frequency of malignancies increases with the intensity and duration of therapy (see section 4.4). Some malignancies may be fatal.
Tabulated summary of adverse drug reactions from clinical trials Adverse drug reactions from clinical trials (Table 2) are listed by MedDRA system organ class. Within each system organ class, the adverse drug reactions are ranked by frequency, with the most frequent reactions first. Within each frequency grouping, adverse drug reactions are presented in order of decreasing seriousness. In addition the corresponding frequency category for each adverse drug reaction is based on the following convention (CIOMS III): very common (>1/10); common (>1/100, <1/10); uncommon (>1/1,000, <1/100); rare (>1/10,000, <1/1,000) very rare (<1/10,000), not known (cannot be estimated from the available data).

* Adverse events reported from post marketing experience where the ADR frequency is not known due to the lack of a real denominator.
Other adverse drug reactions from post-marketing experience There have been solicited and spontaneous reports of hepatotoxicity and liver injury including cholestasis, jaundice hepatitis and liver failure in patients treated with ciclosporin. Most reports included patients with significant co-morbidities, underlying conditions and other confounding factors including infectious complications and comedications with hepatotoxic potential. In some cases, mainly in transplant patients, fatal outcomes have been reported (see section 4.4).
Acute and chronic nephrotoxicity
Patients receiving calcineurin inhibitor (CNI) therapies, including ciclosporin and ciclosporin-containing regimens, are at increased risk of acute or chronic nephrotoxicity. There have been reports from clinical trials and from the postmarketing setting associated with the use of ciclosporin. Cases of acute nephrotoxicity reported disorders of ion homeostasis, such as hyperkalaemia, hypomagnesaemia, and hyperuricaemia. Cases reporting chronic morphological changes included arteriolar hyalinosis, tubular atrophy and interstitial fibrosis (see section 4.4).
Paediatric population
Clinical studies have included children from 1 year of age using standard ciclosporin dosage with a comparable safety profile to adults.
4.9 Overdose
The oral LD50 of ciclosporin is 2,329 mg/kg in mice, 1,480 mg/kg in rats and > 1,000 mg/kg in rabbits.
The intravenous LD50 is 148 mg/kg in mice, 104 mg/kg in rats, and 46 mg/kg in rabbits.
Symptoms
Experience with acute overdosage of ciclosporin is limited. Oral doses of ciclosporin of up to 10 g (about 150 mg/kg) have been tolerated with relatively minor clinical consequences, such as vomiting, drowsiness, headache, tachycardia and in a few patients moderately severe, reversible impairment of renal function. However, serious symptoms of intoxication have been reported following accidental parenteral overdose with ciclosporin in premature neonates.
Treatment
. In all cases of overdosage, general supportive measures should be followed and symptomatic treatment applied Forced emesis and gastric lavage may be of value within the first few hours after oral intake. Ciclosporin is not dialysable to any great extent, nor is it well cleared by charcoal haemoperfusion
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Immunosuppressive agents, calcineurin inhibitors, ATC code
L04AD01.
Ciclosporin (also known as ciclosporin A) is a cyclic poly peptide, which consists of 11 amino acids. It is a potent immunosuppressive agent, which in animals prolongs survival of allogeneic transplants of skin, heart, kidney, pancreas, bone marrow, small intestine or lung. Studies suggest that ciclosporin inhibits the development of cell-mediated reactions, including allograft immunity, delayed cutaneous hypersensitivity,, experimental allergic encephalomyelitis, Freund’s adjuvant arthritis, graft-versus-host disease (GVHD) and also T-cell dependent antibody production. At the cellular level ciclosporin inhibits the production and release of lymphokines, including interleukin 2 (T-cell growth factor, TCGF). Ciclosporin appears to block the resting lymphocytes in the G0 or G1 phase of the cell cycle and inhibits the antigen triggered release of lymphokines by activated T-cells.
All available evidence suggests that ciclosporin acts specifically and reversibly on lymphocytes. Unlike cytostatic agents, it does not depress haemopoiesis and has no effect on the function of phagocytic cells.
Successful solid organ and bone marrow transplantations have been performed in man using ciclosporin to prevent and treat rejection and GVHD. Ciclosporin has been used
successfully both in hepatitis C virus (HCV) positive and HCV negative liver transplants recipients. Beneficial effects of ciclosporin therapy have also been shown in a variety of conditions that are known, or may be considered to be of autoimmune origin.
Paediatric population: Ciclosporin has been shown to be efficacious in steroid-dependent nephrotic syndrome.
5.2 Pharmacokinetic properties
Absorption
The maximal blood concentration (Cmax) is achieved within 1-2 hours (Tmax). The absolute bioavailability is 30-60%. The inter- and intra-individual pharmacokinetic variability is 10-20% for AUC and Cmax in healthy volunteers. Munidex can be administered with food or alone.
Bioequivalence studies under both fasting and fed conditions were performed to compare the pharmacokinetic parameters of Munidex and the originator product, as follows:
1. A randomised, two-way cross-over study in 24 healthy male volunteers under fasting conditions. The results of the study are presented in Table 3 below:

The excretion is primarily biliary, with only 6% of the oral dose excreted in the urine; only 0.1% is excreted in the urine as unchanged parent compound.
There is a high variability in the data reported on the terminal half-life of ciclosporin depending on the assay applied and on the target population. The terminal half-life ranged from 6.3 hours in healthy volunteers to 20.4 hours in patients with severe liver disease (see sections 4.2 and 4.4). The elimination half-life in kidney-transplanted patients was approximately 11 hours, with a range between 4 and 25 hours.
Special populations
Patients with renal impairment
In a study performed in patients with terminal renal failure, the systemic clearance was approximately two thirds of the mean systemic clearance in patients with normally functioning kidneys. Less than 1% of the administered dose is removed by dialysis.
Patients with hepatic impairment
An approximate 2- to 3-fold increase in ciclosporin exposure may be observed in patients with hepatic impairment. In a study performed in severe liver disease patients with biopsy-proven cirrhosis, the terminal half-life was 20.4 hours (range between 10.8 to 48.0 hours) compared to 7.4 to 11.0 hours in healthy subjects.
Paediatric population
Pharmacokinetic data from paediatric patients given ciclosporin are very limited. In 15 renal transplant patients aged 3 -16 years, ciclosporin whole blood clearance after intravenous administration of ciclosporin was 10.6±3.7 ml/min/kg (assay: Cyclo-trac specific RIA). In a study of 7 renal transplant patients aged 2-16 years, the ciclosporin clearance ranged from 9.8 to15.5 ml/min/kg. In 9 liver transplant patients aged 0.65-6 years, clearance was 9.3±5.4 ml/min/kg (assay: HPLC). In comparison to adult transplant populations, the differences in bioavailability between different ciclosporin formulations in paediatrics are comparable to those observed in adults.
5.3 Preclinical safety data
Ciclosporin gave no evidence of mutagenic or teratogenic effects in the standard test systems with oral application (rats up to 17 mg/kg/day and rabbits up to 30 mg/kg/day orally). At toxic doses (rats at 30 mg/kg/day and rabbits at 100 mg/kg/day orally), ciclosporin was embryo- and foetotoxic as indicated by increased prenatal and postnatal mortality, and reduced foetal weight together with related skeletal retardations.
In two published research studies, rabbits exposed to ciclosporin in utero (10 mg/kg/day subcutaneously) demonstrated reduced numbers of nephrons, renal hypertrophy, systemic hypertension, and progressive renal insufficiency up to 35 weeks of age. Pregnant rats which received 12 mg/kg/day of ciclosporin intravenously (twice the recommended human intravenous dose) had foetuses with an increased incidence of ventricular septal defect. These findings have not been demonstrated in other species and their relevance for humans is unknown. No impairment in fertility was demonstrated in studies in male and female rats.
Ciclosporin was tested in a number of in vitro and in vivo tests for genotoxicity with no evidence for a clinically relevant mutagenic potential.
Carcinogenicity studies were carried out in male and female rats and mice. In the 78-week mouse study, at doses of 1, 4, and 16 mg/kg/day, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value. In the 24-month rat study conducted at 0.5, 2, and
8 mg/kg/day, pancreatic islet cell adenomas significantly exceeded the control rate at the low dose level. The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related.

The results show that food intake decreases AUC and Cmax by 7% and 15%, respectively, compared to the values obtained under fasting conditions.
The reduction in AUC and Cmax are not significant and Munidex can be administered with or without food.
Distribution
Ciclosporin is distributed largely outside the blood volume, with an average apparent distribution volume of 3.5 l/kg. In the blood, 33 to 47% is present in plasma, 4 to 9% in lymphocytes, 5 to 12% granulocytes, and 41 to 58% in the erythrocytes. In plasma approximately 90% is bound to proteins, mostly lipoproteins.
Biotransformation
Ciclosporin is extensively metabolised to approximately 15 metabolites. Metabolism mainly takes place in the liver via cytochrome P450 3A4 (CYP3A4), and the main pathways of metabolism consist of mono- and dihydroxylation and N-demethylation at various positions of the molecule. All metabolites identified so far contain the intact peptide structure of the parent compound; some possess weak immunosuppressive activity (up to one-tenth that of the unchanged drug).
Elimination
