Indications

Adult Dosage

Rapamune is for oral use only.

Bioavailability has not been determined for tablets after they have been crushed, chewed or split and therefore this cannot be recommended.

Treatment should be initiated by and remain under the guidance of an appropriately qualified specialist in transplantation.

Use in adults

Initial therapy (2 to 3 months post-transplantation): The usual dosage regimen for Rapamune is a 6 mg oral loading dose, administered as soon as possible after transplantation, followed by 2 mg once daily. The Rapamune dose should then be individualised, to obtain whole blood trough levels of 4 to 12 ng/ml. Rapamune therapy should be optimised with a tapering regimen of steroids and ciclosporin microemulsion. Suggested ciclosporin trough concentration ranges for the first 2-3 months after transplantation are 150-400 ng/ml (monoclonal assay or equivalent technique).

Maintenance Therapy: Ciclosporin should be progressively discontinued over 4 to 8 weeks and the Rapamune dose should be adjusted to obtain whole blood trough levels of 12 to 20 ng/ml (chromatographic assay; see Therapeutic drug monitoring). Rapamune should be given with corticosteroids. In patients for whom ciclosporin withdrawal is either unsuccessful or cannot be attempted, the combination of ciclosporin and Rapamune should not be maintained for more than 3 months post-transplantation. In such patients, when clinically appropriate, Rapamune should be discontinued and an alternative immunosuppressive regimen instituted.

Use in black recipients: There is limited information indicating that black renal transplant recipients (predominantly African-American) require higher doses and trough levels of sirolimus to achieve the same efficacy as observed in non-black patients. Currently, the efficacy and safety data are too limited to allow specific recommendations for use of sirolimus in black recipients.

Use in children and adolescents(<18 years): The available data on safety and efficacy are not sufficient to recommend the use of Rapamune in children and adolescents less than 18 years of age. Limited pharmacokinetic information is available in children and adolescents.

Use in elderly patients (> 65 years): Clinical studies of Rapamune did not include a sufficient number of patients>65 years of age to determine whether they will respond differently than younger patients. Sirolimus trough concentration data in 35 renal transplant patients>65 years of age were similar to those in the adult population (n=822) from 18 to 65 years of age.

Use in patients with renal impairment: No dosage adjustment is required.

Use in patients with hepatic impairment: The clearance of sirolimus may be reduced in patients with impaired hepatic function. In patients with severe hepatic impairment, it is recommended that the maintenance dose of Rapamune be reduced by approximately one half.

It is recommended that sirolimus whole blood trough levels be closely monitored in patients with impaired hepatic function (see Therapeutic drug monitoring). It is not necessary to modify the Rapamune loading dose.

Therapeutic drug monitoring: Most patients who received 2 mg of Rapamune 4 hours after ciclosporin had whole blood trough concentrations of sirolimus within the 4 to 12 ng/ml target range (expressed as chromatographic assay values). Optimal therapy requires therapeutic drug concentration monitoring in all patients. Whole blood sirolimus levels should be closely monitored in the following populations: (1) in patients with hepatic impairment; (2) when inducers or inhibitors of CYP3A4 are concurrently administered and after their discontinuation; and/or (3) if ciclosporin dosing is markedly reduced or discontinued, as these populations are most likely to have special dosing requirements.

Therapeutic drug monitoring should not be the sole basis for adjusting sirolimus therapy. Careful attention should be made to clinical signs/symptoms, tissue biopsies, and laboratory parameters.

To minimise variability, Rapamune should be taken at the same time in relation to ciclosporin, 4 hours after the ciclosporin dose, and consistently either with or without food. Optimally, adjustments in Rapamune dosage should be based on more than a single trough level obtained>5 days after a previous dosing change.

Following the discontinuation of ciclosporin therapy, a target trough range of 12 to 20 ng/ml (chromatographic assay) is recommended. Ciclosporin inhibits the metabolism of sirolimus, and consequently, sirolimus levels will decrease when ciclosporin is discontinued unless the sirolimus dose is increased. On average, the sirolimus dose will need to be 4-fold higher to account for both the absence of the pharmacokinetic interaction (2-fold increase) and the augmented immunosuppressive requirement in the absence of ciclosporin (2-fold increase). The rate at which the dose of sirolimus is increased should correspond to the rate of ciclosporin elimination.

If further dose adjustment(s) are required during maintenance therapy (after discontinuation of ciclosporin), in most patients these adjustments can be based on simple proportion: new Rapamune dose = current dose x (target concentration/current concentration). A loading dose should be considered in addition to a new maintenance dose when it is necessary to considerably increase sirolimus trough concentrations: Rapamune loading dose = 3 x (new maintenance dose – current maintenance dose). The maximum Rapamune dose administered on any day should not exceed 40 mg. If an estimated daily dose exceeds 40 mg due to the addition of a loading dose, the loading dose should be administered over 2 days. Sirolimus trough concentrations should be monitored at least 3 to 4 days after a loading dose(s).

In patients with severe hepatic impairment, monitoring should be performed every 5 to 7 days until 3 consecutive trough levels have shown stable concentrations of sirolimus after dose adjustment or after loading dose due to the delay in reaching steady state because of the prolonged half-life.

The recommended 24-hour trough concentration ranges for sirolimus are based on chromatographic methods. Several assay methodologies have been used to measure the whole blood concentrations of sirolimus. Currently in clinical practice, sirolimus whole blood concentration are being measured by both chromatographic and immunoassay methodologies. The concentration values obtained by these different methodologies are not interchangeable. When using a proprietary immunoassay system, always refer to the manufacturer's information to correlate values to a reference chromatographic assay. All sirolimus concentrations reported in this Summary of Product Characteristics were either measured using chromatographic methods or have been converted to chromatographic method equivalents. Adjustments to the targeted range should be made according to the assay being utilised to determine the sirolimus trough concentrations.

Other considerations for use: Ciclosporin (microemulsion) and other medicinal or non-medicinal products may interact with sirolimus.

Child Dosage

Contra Indications

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

Special Precautions

Rapamune has not been adequately studied in patients at high immunological risk, therefore use is not recommended in this group of patients.

In patients with delayed graft function, sirolimus may delay recovery of renal function.

Hypersensitivity reactions

Hypersensitivity reactions, including anaphylactic/anaphylactoid reactions, angioedema, exfoliative dermatitis, and hypersensitivity vasculitis, have been associated with the administration of sirolimus. 

Concomitant therapy

Immunosuppressive agents

Sirolimus has been administered concurrently with the following agents in clinical studies: tacrolimus, ciclosporin, azathioprine, mycophenolate mofetil, corticosteroids and cytotoxic antibodies. Sirolimus in combination with other immunosuppressive agents has not been extensively investigated.

Renal function should be monitored during concomitant administration of Rapamune and ciclosporin. Appropriate adjustment of the immunosuppression regimen should be considered in patients with elevated serum creatinine levels. Caution should be exercised when coadministering other agents that are known to have a deleterious effect on renal function.

Patients treated with ciclosporin and Rapamune beyond 3 months had higher serum creatinine levels and lower calculated glomerular filtration rates compared to patients treated with ciclosporin and placebo or azathioprine controls. Patients who were successfully withdrawn from ciclosporin had lower serum creatinine levels and higher calculated glomerular filtration rates, as well as lower incidence of malignancy, compared to patients remaining on ciclosporin. The continued coadministration of ciclosporin and Rapamune as maintenance therapy cannot be recommended.

Based on information from subsequent clinical studies, the use of Rapamune, mycophenolate mofetil, and corticosteroids, in combination with IL2 receptor antibody (IL2R Ab) induction, is not recommended in the de novo renal transplant setting.

Periodic quantitative monitoring of urinary protein excretion is recommended. In a study evaluating conversion from calcineurin inhibitors to Rapamune in maintenance renal transplant patients, increased urinary protein excretion was commonly observed at 6 to 24 months after conversion to Rapamune (see section 5.1). New onset nephrosis (nephrotic syndrome) was also reported in 2% of the patients in the study. The safety and efficacy of conversion from calcineurin inhibitors to Rapamune in maintenance renal transplant patients have not been established.

The concomitant use of Rapamune with a calcineurin inhibitor may increase the risk of calcineurin inhibitorinduced haemolytic uraemic syndrome/thrombotic thrombocytopaenic purpura/thrombotic microangiopathy (HUS/TTP/TMA).

HMG-CoA reductase inhibitors

In clinical studies, the concomitant administration of Rapamune and HMGCoA reductase inhibitors and/or fibrates was welltolerated. During Rapamune therapy with or without CsA, patients should be monitored for elevated lipids, and patients administered an HMGCoA reductase inhibitor and/or fibrate should be monitored for the possible development of rhabdomyolysis and other adverse reactions, as described in the respective Summary of Product Characteristics of these agents.

Cytochrome P450 isozymes

Coadministration of sirolimus with strong inhibitors of CYP3A4 (such as ketoconazole, voriconazole, itraconazole, telithromycin or clarithromycin) or inducers of CYP3A4 (such as rifampin, rifabutin) is not recommended.

Angiotensin-converting enzyme inhibitors (ACE)

The concomitant administration of sirolimus and angiotensinconverting enzyme inhibitors has resulted in angioneurotic oedematype reactions.

Vaccination

Immunosuppressants may affect response to vaccination. During treatment with immunosuppressants, including Rapamune, vaccination may be less effective. The use of live vaccines should be avoided during treatment with Rapamune.

Malignancy

Increased susceptibility to infection and the possible development of lymphoma and other malignancies, particularly of the skin, may result from immunosuppression. As usual for patients with increased risk for skin cancer, exposure to sunlight and UV light should be limited by wearing protective clothing and using a sunscreen with a high protection factor.

Infections

Oversuppression of the immune system can also increase susceptibility to infection, including opportunistic infections (bacterial, fungal, viral and protozoal), fatal infections, and sepsis.

Among these conditions are BK virusassociated nephropathy and JC virusassociated progressive multifocal leukoencephalopathy (PML). These infections are often related to a high total immunosuppressive burden and may lead to serious or fatal conditions that physicians should consider in the differential diagnosis in immunosuppressed patients with deteriorating renal function or neurological symptoms.

Cases of Pneumocystis carinii pneumonia have been reported in patients not receiving antimicrobial prophylaxis. Therefore, antimicrobial prophylaxis for Pneumocystis carinii pneumonia should be administered for the first 12 months following transplantation.

Cytomegalovirus (CMV) prophylaxis is recommended for 3 months after transplantation, particularly for patients at increased risk for CMV disease.

Hepatic impairment

In hepatically impaired patients, it is recommended that sirolimus whole blood trough levels be closely monitored. In patients with severe hepatic impairment, reduction in maintenance dose by one half is recommended based on decreased clearance. Since halflife is prolonged in these patients, therapeutic monitoring of the medicinal product after a loading dose or a change of dose should be performed for a prolonged period of time until stable concentrations are reached.

Lung and liver transplant populations

The safety and efficacy of Rapamune as immunosuppressive therapy have not been established in liver or lung transplant patients, and therefore such use is not recommended.

In two clinical studies in de novo liver transplant patients, the use of sirolimus plus ciclosporin or tacrolimus was associated with an increase in hepatic artery thrombosis, mostly leading to graft loss or death.

A clinical study in liver transplant patients randomised to conversion from a calcineurin inhibitor (CNI)based regimen to a sirolimusbased regimen versus continuation of a CNIbased regimen 6144 months postliver transplantation failed to demonstrate superiority in baselineadjusted GFR at 12 months (-4.45 ml/min and -3.07 ml/min, respectively). The study also failed to demonstrate noninferiority of the rate of combined graft loss, missing survival data, or death for the sirolimus conversion group compared to the CNI continuation group. The rate of death in the sirolimus conversion group was higher than the CNI continuation group, although the rates were not significantly different. The rates of premature study discontinuation, adverse events overall (and infections, specifically), and biopsyproven acute liver graft rejection at 12 months were all significantly greater in the sirolimus conversion group compared to the CNI continuation group.

Cases of bronchial anastomotic dehiscence, most fatal, have been reported in de novo lung transplant patients when sirolimus has been used as part of an immunosuppressive regimen.

Systemic effects

There have been reports of impaired or delayed wound healing in patients receiving Rapamune, including lymphocele and wound dehiscence. Patients with a body mass index (BMI) greater than 30 kg/m² may be at increased risk of abnormal wound healing based on data from the medical literature.

There have also been reports of fluid accumulation, including peripheral oedema, lymphoedema, pleural effusion and pericardial effusions (including haemodynamically significant effusions in children and adults), in patients receiving Rapamune.

The use of Rapamune in renal transplant patients was associated with increased serum cholesterol and triglycerides that may require treatment. Patients administered Rapamune should be monitored for hyperlipidaemia using laboratory tests and if hyperlipidaemia is detected, subsequent interventions such as diet, exercise, and lipidlowering agents should be initiated. The risk/benefit should be considered in patients with established hyperlipidaemia before initiating an immunosuppressive regimen, including Rapamune. Similarly the risk/benefit of continued Rapamune therapy should be reevaluated in patients with severe refractory hyperlipidaemia.

Sucrose and lactose

Sirolimus tablets contain sucrose and lactose.

Sucrose

Patients with rare hereditary problems of fructose intolerance, glucosegalactose malabsorption or sucraseisomaltase insufficiency should not take this medicine.

Lactose

Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucosegalactose malabsorption should not take this medicine.

Interactions

Sirolimus is extensively metabolised by the CYP3A4 isozyme in the intestinal wall and liver. Sirolimus is also a substrate for the multidrug efflux pump, P-glycoprotein (P-gp) located in the small intestine. Therefore, absorption and the subsequent elimination of sirolimus may be influenced by substances that affect these proteins. Inhibitors of CYP3A4 (such as ketoconazole, voriconazole, itraconazole, telithromycin, or clarithromycin) decrease the metabolism of sirolimus and increase sirolimus levels. Inducers of CYP3A4 (such as rifampin or rifabutin) increase the metabolism of sirolimus and decrease sirolimus levels. Co-administration of sirolimus with strong inhibitors of CYP3A4 or inducers of CYP3A4 is not recommended.

Ciclosporin (CYP3A4 substrate): The rate and extent of sirolimus absorption was significantly increased by ciclosporin A (CsA). Sirolimus administered concomitantly (5 mg), and at 2h (5 mg) and 4h (10 mg) after CsA (300 mg) resulted in increased sirolimus AUC by approximately 183%, 141% and 80% respectively. The effect of CsA was also reflected by increases in sirolimus C_max and t_max. When given 2 hours before CsA administration, sirolimus C_max and AUC were not affected. Single-dose sirolimus did not affect the pharmacokinetics of ciclosporin (microemulsion) in healthy volunteers when administered simultaneously or 4 hours apart. It is recommended that Rapamune be administered 4 hours after ciclosporin (microemulsion).

Rifampicin (CYP3A4 inducer): Administration of multiple doses of rifampicin decreased sirolimus whole blood concentrations following a single 10 mg dose of Rapamune oral solution. Rifampicin increased the clearance of sirolimus by approximately 5.5-fold and decreased AUC and C_max by approximately 82% and 71%, respectively. Co-administration of sirolimus and rifampicin is not recommended.

Ketoconazole (CYP3A4 inhibitor): Multiple-dose ketoconazole administration significantly affected the rate and extent of absorption and sirolimus exposure as reflected by increases in sirolimus C_max, t_max, and AUC of 4.4-fold, 1.4-fold, and 10.9-fold, respectively. Co-administration of sirolimus and ketoconazole is not recommended (see section 4.4).

Voriconazole (CYP3A4 inhibitor): Co-administration of sirolimus (2 mg single dose) with multiple-dose administration of oral voriconazole (400 mg every 12 hours for 1 day, then 100 mg every 12 hours for 8 days) in healthy subjects has been reported to increase sirolimus C_max and AUC by an average of 7-fold and 11-fold respectively. Co-administration of sirolimus and voriconazole is not recommended.

Diltiazem (CYP3A4 inhibitor): The simultaneous oral administration of 10 mg of Rapamune oral solution and 120 mg of diltiazem significantly affected the bioavailability of sirolimus. Sirolimus C_max, t_max, and AUC were increased 1.4-fold, 1.3-fold, and 1.6-fold, respectively. Sirolimus did not affect the pharmacokinetics of either diltiazem or its metabolites desacetyldiltiazem and desmethyldiltiazem. If diltiazem is administered, sirolimus blood levels should be monitored and a dose adjustment may be necessary.

Verapamil (CYP3A4 inhibitor): Multiple-dose administration of verapamil and sirolimus oral solution significantly affected the rate and extent of absorption of both drugs. Whole blood sirolimus C_max, t_max, and AUC were increased 2.3-fold, 1.1-fold, and 2.2-fold, respectively. Plasma S-(-) verapamil C_max and AUC were both increased 1.5-fold, and t_max was decreased 24%. Sirolimus levels should be monitored and appropriate dose reductions of both medications should be considered.

Erythromycin (CYP3A4 inhibitor):Multiple-dose administration of erythromycin and sirolimus oral solution significantly increased the rate and extent of absorption of both drugs. Whole blood sirolimus C_max, t_max, and AUC were increased 4.4-fold, 1.4-fold, and 4.2-fold, respectively. The C_max, t_max, and AUC of plasma erythromycin base were increased 1.6-fold, 1.3-fold, and 1.7-fold, respectively. Sirolimus levels should be monitored and appropriate dose reductions of both medications should be considered.

Oral contraceptives: No clinically significant pharmacokinetic interaction was observed between sirolimus and 0.3 mg norgestrel/ 0.03 mg ethinyl estradiol. Although the results of a single dose drug interaction study with an oral contraceptive suggest the lack of a pharmacokinetic interaction, the results cannot exclude the possibility of changes in the pharmacokinetics that might affect the efficacy of the oral contraceptive during long term treatment with Rapamune.

Other possible interactions

Moderate and weak inhibitors of CYP3A4 may decrease the metabolism of sirolimus and increase sirolimus blood levels (e.g. calcium channel blockers: nicardipine; antifungal agents: clotrimazole, fluconazole; antibiotics: troleandomycin; other substances: bromocriptine, cimetidine, danazol, protease inhibitors).

Inducers of CYP3A4 may increase the metabolism of sirolimus and decrease sirolimus blood levels (e.g. St. John's wort (Hypericum perforatum), anticonvulsants: carbamazepine, phenobarbital, phenytoin).

Although sirolimus inhibits human liver microsomal cytochrome P₄₅₀ CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5 in vitro, the active substance is not expected to inhibit the activity of these isozymes in vivo since the sirolimus concentrations necessary to produce inhibition are much higher than those observed in patients receiving therapeutic doses of Rapamune. Inhibitors of P-gp may decrease the efflux of sirolimus from intestinal cells and increase sirolimus levels.

Grapefruit juice affects CYP3A4 mediated metabolism and should therefore be avoided.

Pharmacokinetic interactions may be observed with gastrointestinal prokinetic agents such as cisapride and metoclopramide.

No clinically significant pharmacokinetic interaction was observed between sirolimus and any of the following substances: acyclovir, atorvastatin, digoxin, glibenclamide, methylprednisolone, nifedipine, prednisolone, and trimethoprim/sulphamethoxazole.

Adverse Reactions

The most commonly reported adverse drug reactions (occurring in >10% of patients) are thrombocytopenia, anaemia, pyrexia, hypertension, hypokalaemia, hypophosphataemia, urinary tract infection, hypercholesterolaemia, hyperglycaemia, hypertriglyceridaemia, abdominal pain, lymphocoele, peripheral oedema, arthralgia, acne, diarrhoea, pain, constipation, nausea, headache, increased blood creatinine, and increased blood lactate dehydrogenase (LDH).

The incidence of any adverse event(s) may increase as the trough sirolimus level increases.

Adverse reactions based on experience from clinical trials and postmarketing experience are presented in the following table by system organ class and frequency of occurrence. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness. Only events for which there is at least reasonable suspicion of a causal relationship to Rapamune treatment are listed.

Most patients were on immunosuppressive regimens which included Rapamune in combination with other immunosuppressive agents.

Immunosuppression increases the susceptibility to the development of lymphoma and other malignancies, particularly of the skin.

Cases of BK virus associated nephropathy, as well as cases of JC virus associated progressive multifocal leukoencephalopathy (PML), have been reported in patients treated with immunosuppressants, including Rapamune.

Hepatotoxicity has been reported, the risk may increase as the trough sirolimus level increases. There have been rare reports of fatal hepatic necrosis with elevated trough sirolimus levels.

Cases of interstitial lung disease (including pneumonitis and infrequently bronchiolitis obliterans organising pneumonia (BOOP) and pulmonary fibrosis), some fatal, with no identified infectious etiology have occurred in patients receiving immunosuppressive regimens including Rapamune. In some cases, the interstitial lung disease has resolved upon discontinuation or dose reduction of Rapamune. The risk may be increased as the trough sirolimus level increases.

Impaired healing following transplant surgery has been reported, including fascial dehiscence,incisional hernia, and anastomotic disruption (e.g. wound, vascular, airway, ureteral, biliary).

Impairments of sperm parameters have been observed among some patients treated with Rapamune. These effects have been reversible upon discontinuation of Rapamune in most cases.

In patients with delayed graft function, sirolimus may delay recovery of renal function.

The concomitant use of sirolimus with a calcineurin inhibitor may increase the risk of calcineurin inhibitor-induced HUS/TTP/TMA.

Focal segmental glomerulosclerosis has been reported.

In an ongoing study evaluating the safety and efficacy of conversion from calcineurin inhibitors to sirolimus (target levels of 12 - 20 ng/mL) in maintenance renal transplant patients, enrollment was stopped in the subset of patients (n=90) with a baseline glomerular filtration rate of less than 40 mL/min. There was a higher rate of serious adverse events including pneumonia, acute rejection, graft loss and death in this sirolimus treatment arm (n=60, median time post-transplant 36 months).

Paediatric population

Controlled clinical trials with posology comparable to that currently indicated for the use of Rapamune in adults—that is, use in combination with ciclosporin and corticosteroids for 2 to 3 months posttransplantation followed by withdrawal of ciclosporin thereafter—have not been conducted in children or adolescents (<18 years of age).

Safety was assessed in a controlled clinical trial enrolling renal transplant patients <18 years of age considered of high-immunologic risk, defined as a history of one or more acute allograft rejection episodes and/or the presence of chronic allograft nephropathy on a renal biopsy. The use of Rapamune in combination with calcineurin inhibitors and corticosteroids was associated with an increased risk of deterioration of renal function, serum lipid abnormalities (including but not limited to increased serum triglycerides and cholesterol), and urinary tract infections. The treatment regimen studied (continuous use of Rapamune in combination with calcineurin inhibitor) is not indicated for adult or paediatric patients.

In another study enrolling renal transplant patients 20 years of age that was intended to assess the safety of progressive corticosteroid withdrawal (beginning at six months post-transplantation) from an immunosuppressive regimen initiated at transplantation that included full-dose immunosuppression with both Rapamune and a calcineurin inhibitor in combination with basiliximab induction, of the 274 patients enrolled, 19 (6.9%) were reported to have developed post-transplant lymphoproliferative disorder (PTLD). Among 89 patients known to be EBV seronegative prior to transplantation, 13 (15.6%) were reported to have developed PTLD. All patients who developed PTLD were aged <18 years.

There is insufficient experience to recommend the use of Rapamune in children and adolescents.
