WARNING: MALIGNANCIES AND SERIOUS INFECTIONS, KIDNEY GRAFT THROMBOSIS; NEPHROTOXICITY; AND MORTALITY IN HEART TRANSPLANTATION
Malignancies and Serious Infections
- Only physicians experienced in immunosuppressive therapy and management of transplant patients should prescribe everolimus tablets. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient. [See Warnings and Precautions (5.1) ]
- Increased susceptibility to infection and the possible development of malignancies such as lymphoma and skin cancer may result from immunosuppression. [See Warnings and Precautions (5.2 and 5.3)]
Kidney Graft Thrombosis
- An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days post-transplantation [see Warnings and Precautions (5.4) ]
Nephrotoxicity
- Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with evrolimus. Therefore reduced doses of cyclosporine should be used in combination with everolimus in order to reduce renal dysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations[see Dosage and Administration (2.4, 2.5),Warnings and Precautions (5.6), Clinical Pharmacology (12.7, 12.8)]
Mortality in Heart Transplantation
- Increased mortality, often associated with serious infections, within the first three months post-transplantation was observed in a clinical trial of de novo heart transplant patients receiving immunosuppressive regimens with or without induction therapy. Use in heart transplantation is not recommended. [See Warnings and Precautions (5.7)]
1 INDICATIONS AND USAGE
1.1 Prophylaxis of Organ Rejection in Kidney Transplantation
Everolimus tablets are indicated for the prophylaxis of organ rejection in adult patients at low-moderate immunologic risk receiving a kidney transplant [see Clinical Studies (14.1) ] Everolimus is to be administered in combination with basiliximab induction and concurrently with reduced doses of cyclosporine and with corticosteroids. TDM of everolimus and cyclosporine is recommended for all patients receiving these products. [see Dosage and Administration (2.2, 2.3)]
1.2 Prophylaxis of Organ Rejection in Liver Transplantation
Everolimus is indicated for the prophylaxis of allograft rejection in adult patients receiving a liver transplant. Everolimus is to be administered no earlier than 30 days post-transplant concurrently in combination with reduced doses of tacrolimus and with corticosteroids [See Warnings and Precautions (5.5) and Clinical Studies (14.2)]. Therapeutic drug monitoring (TDM) of everolimus and tacrolimus is recommended for all patients receiving these products. [See Dosage and Administration (2.3, 2.5)]
1.3 Limitations of Use
The safety and efficacy of everolimus has not been established in the following populations:
- Kidney transplant patients at high immunologic risk
- Recipients of transplanted organs other than kidney or liver [See Warnings and Precautions (5.7) ]
- Pediatric patients (less than 18 years).
2 DOSAGE AND ADMINISTRATION
Patients receiving everolimus may require dose adjustments based on everolimus blood concentrations achieved, tolerability, individual response, change in concomitant medications and the clinical situation. Optimally, dose adjustments of everolimus should be based on trough concentrations obtained 4 or 5 days after a previous dosing change. Dose adjustment is required if the trough concentration is below 3ng/mL. The total daily dose of everolimus should be doubled using the available tablet strengths (0.25 mg, 0.5 mg, 0.75 mg or 1 mg). Dose adjustment is also required if the trough concentration is greater than 8 ng/mL on 2 consecutive measures; the dose of everolimus should be decreased by 0.25 mg twice daily [See Dosage and Administration (2.3), Clinical Pharmacology (12.3)]
2.1 Dosage in Adult Kidney Transplant Patients
An initial everolimus dose of 0.75 mg orally twice daily (1.5 mg per day) is recommended for adult kidney transplant patients in combination with reduced dose cyclosporine, administered as soon as possible after transplantation. [see Dosage and Administration (2.3, 2.4), Clinical Studies (14.1)].
Oral prednisone should be initiated once oral medication is tolerated. Steroid doses may be further tapered on an individualized basis depending on the clinical status of patient and function of graft.
2.2 Dosage in Adult Liver Transplant Patients
Start everolimus at least 30 days post-transplant. An initial dose of 1 mg orally twice daily (2 mg per day) is recommended for adult liver transplant patients in combination with reduced dose tacrolimus. [See Dosage and Administration (2.3, 2.5), Clinical Studies (14.2)]
Steroid doses may be further tapered on an individualized basis depending on the clinical status of patient and function of graft.
2.3 Therapeutic Drug Monitoring (TDM) — Everolimus
Routine everolimus whole blood therapeutic drug concentration monitoring is recommended for all patients. The recommended everolimus therapeutic range is 3 to 8 ng/mL. [See Clinical Pharmacology (12.7) ] Careful attention should be made to clinical signs and symptoms, tissue biopsies, and laboratory parameters. It is important to monitor everolimus blood concentrations, in patients with hepatic impairment, during concomitant administration of CYP3A4 inducers or inhibitors, when switching cyclosporine formulations and/or when cyclosporine dosing is reduced according to recommended target concentrations [see Clinical Pharmacology (12.7, 12.8)].
There is an interaction of cyclosporine on everolimus, and consequently, everolimus concentrations may decrease if cyclosporine exposure is reduced. There is little to no pharmacokinetic interaction of tacrolimus on everolimus, and thus, everolimus concentrations do not decrease if the tacrolimus exposure is reduced. [See Drug Interactions (7.12) ]
The everolimus recommended therapeutic range of 3 to 8 ng/mL is based on an LC/MS/MS assay method. Currently in clinical practice, everolimus whole blood trough concentrations may be measured by chromatographic or immunoassay methodologies. Because the measured everolimus whole blood trough concentrations depend on the assay used, individual patient sample concentration values from different assays may not be interchangeable. Consideration of assay results must be made with knowledge of the specific assay used. Therefore, communication should be maintained with the laboratory performing the assay.
