Medically reviewed by Drugs.com on Jun 10, 2024. Written by ASHP.

Warning

    Management by Experienced Physicians
  • Only clinicians experienced in immunosuppressive therapy and management of transplant patients should prescribe everolimus (i.e., Zortress).

    Malignancies and Serious Infections
  • Patients should be managed in facilities with adequate laboratory and supportive medical resources; the clinician responsible for maintenance therapy should have complete information for patient follow-up.

  • Immunosuppression may result in increased susceptibility to infection and possible development of malignancies (e.g., lymphoma, skin cancer).

    Kidney Graft Thrombosis
  • Increased risk of kidney arterial and venous thrombosis, resulting in graft loss; occurs principally within the first 30 days posttransplantation.

    Nephrotoxicity
  • Risk of nephrotoxicity may be increased with concomitant use of standard dosages of cyclosporine and everolimus. Reduce dosage of cyclosporine when used in combination with everolimus; monitor cyclosporine and everolimus whole blood trough concentrations.

    Mortality in Cardiac Transplantation
  • Increased mortality, often associated with serious infections, observed within the first 3 months after transplantation in patients receiving everolimus in an immunosuppressive regimen with or without induction therapy in a clinical trial of de novo cardiac transplant patients; use of everolimus in cardiac transplantation is not recommended.

Introduction

Antineoplastic and macrolide immunosuppressive agent; inhibitor of mammalian target of rapamycin (mTOR) kinase.

Uses for Everolimus

Breast Cancer

Treatment (in combination with exemestane) of advanced hormone receptor-positive, human epidermal growth factor receptor type 2 (HER2)-negative breast cancer in postmenopausal women following failure of letrozole or anastrozole therapy.

Guidelines generally support the use of everolimus in combination with exemestane in postmenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer in the second- or subsequent-line setting following treatment with a non-steroidal aromatase inhibitor.

Neuroendocrine Tumors

Treatment of progressive neuroendocrine tumors (NET) of pancreatic origin (PNET) in adults with unresectable, locally advanced, or metastatic disease (designated an orphan drug by FDA for this use).

Treatment of progressive, well-differentiated, non-functional NET of GI or lung origin (designated an orphan drug by FDA for this use).

Guidelines generally support consideration of everolimus among other options for the management of progressive PNET and NET of GI and lung origin.

Not indicated for use in patients with functional carcinoid tumors.

Renal Cell Carcinoma

Treatment of advanced renal cell carcinoma (RCC) in adults following failure of sunitinib and/or sorafenib therapy.

Guidelines generally support the use of everolimus in combination with lenvatinib [off-label] for the treatment of advanced RCC in patients who experience disease progression; some experts support the use of everolimus as monotherapy for certain patients with advanced RCC in the second- and subsequent-line treatment setting.

Renal Angiomyolipoma with Tuberous Sclerosis Complex

Treatment of renal angiomyolipoma with tuberous sclerosis complex (TSC), not requiring immediate surgery, in adults (designated an orphan drug by FDA for this use).

Guidelines generally support the use of everolimus as initial therapy for asymptomatic TSC-associated angiomyolipoma over 3 cm in diameter.

Subependymal Giant Cell Astrocytoma with TSC

Treatment of subependymal giant celll astrocytoma (SEGA) with TSC in patients ≥1 year of age when SEGA requires therapeutic intervention but cannot be curatively resected (designated an orphan drug by FDA for this use).

Guidelines generally support the use of everolimus in management of TSC-associated SEGA in patients who do not have an urgent indication for surgery, are not candidates for surgery, or prefer medical treatment.

TSC-Associated Partial-Onset Seizures

Adjunctive treatment of adult and pediatric patients aged ≥2 years with TSC-associated partial-onset seizures (designated an orphan drug by FDA for this use).

Guidelines generally support the use of everolimus for TSC-associated seizures alongside other options in this setting.

Renal Allotransplantation

Prevention of rejection of renal allografts in adults with low to moderate immunologic risk. Used with basiliximab induction therapy and concurrent corticosteroids and reduced dosages of cyclosporine.

Safety and efficacy not established in renal transplant recipients with high immunologic risk or in recipients of transplanted organs other than kidney and liver, or pediatric patients.

The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) guideline on renal transplantation generally recommends use of everolimus-containing immunosuppressive regimens only in patients unable to receive recommended standard therapy, and recommends against its combined use with a calcineurin inhibitor (CNI). A consensus guideline on maintenance immunosuppression in solid organ transplant recipient published in 2022 by the American College of Clinical Pharmacy (ACCP), American Transplantation Society (AST), and International Society for Heart and Lung Transplantation (ISHLT) generally recommends consideration of an mTOR inhibitor alongside or in place of certain immunosuppresants to minimize risk of renal dysfunction or in cases of intolerance of other agents in kidney transplant recipients, and notes that mTOR inhibitor-containing immunosuppression may reduce risks of de novo post-transplant malignancy and cytomegalovirus in this setting.

Hepatic Allotransplantation

Prevention of rejection of hepatic allografts in adults. Used ≥30 days posttransplant concurrently with tacrolimus (in reduced dosages) and corticosteroids.

Safety and efficacy not established in recipients of transplanted organs other than kidney and liver or pediatric patients.

In liver transplant recipients, the ACCP/AST/ISHLT 2022 guideline for maintenance immunosuppression in solid organ transplant recipients generally recommends consideration of an mTOR inhibitor alongside or in place of certain immunosuppresants to minimize risk of renal dysfunction or in cases of intolerance of other agents, and notes that mTOR inhibitor-containing immunosuppression may reduce risk of de novo post-transplant malignancy in this setting.

Heart Allotransplantation

Has been used for the prevention of heart transplant rejection [off-label].

The 2022 ACCP/AST/ISHLT consensus guideline for maintenance immunosuppression in solid organ transplant recipients recommends consideration of mTOR inhibitors, including everolimus or sirolimus, alongside low-dose CNI, MPA, with or without corticosteroids, or as a replacement for CNI or antimetabolites, to minimize risk of kidney dysfunction in heart transplant recipients. The expert panel notes that mTOR inhibitors may protect against cytomegalovirus infection, may be useful in patients with cancer due to reduced risk of de novo and recurrent malignancy post-transplant, and are associated with prevention and reduced progression of cardiac allograft vasculopathy in heart transplant recipients.

Lung Allotransplantation

Has been used for the prevention of lung transplant rejection [off-label] .

The 2022 ACCP/AST/ISHLT consensus guideline for maintenance immunosuppression in solid organ transplant recipients recommends consideration of mTOR inhibitors, including everolimus or sirolimus, alongside low-dose CNI, MPA, with or without corticosteroids to minimize risk of kidney dysfunction in lung transplant recipients. The expert panel notes that mTOR inhibitors may protect against cytomegalovirus infection and that their use in place of antimetabolites may reduce risk of bronchiolitis obliterans syndrome in this setting.

Pancreas Allotransplantation

Has been used for the prevention of pancreas transplant rejection [off-label].

The 2022 ACCP/AST/ISHLT consensus guideline for maintenance immunosuppression in solid organ transplant recipients recommends consideration of mTOR inhibitors, including everolimus or sirolimus, as a replacement for CNI to minimize risk of kidney dysfunction in pancreas transplant recipients. The expert panel notes that mTOR inhibitors may be useful in the setting of MPA intolerance; in patients with MPA-induced GI toxicity, replacement with an mTOR inhibitor may be considered if the mTOR inhibitor is used in combination with tacrolimus with or without corticosteroids to minimize risk of rejection.

Vascularized Composite Allotransplantation

Has been used for the prevention of vascularized composite transplant rejection [off-label] in a limited number of patients undergoing hand transplantation and uterus transplantation; larger studies are required to define the standard of care in this setting.

Premedication and Prophylaxis

Dispensing and Administration Precautions

Administration

Oral Administration

Administer orally at the same time every day (or approximately 12 hours apart when given twice daily), either consistently with food or consistently without food.

Available as tablets (Afinitor, Zortress) and as tablets for oral suspension (Afinitor Disperz). Afinitor Disperz is recommended only for treatment of SEGA with TSC and as adjunctive treatment for partial-onset seizures with TSC.

Do not combine dosage forms to achieve desired dose; use only one dosage form.

If a dose of Afinitor or Afinitor Disperz is missed, the dose can be administered up to 6 hours later. If more than 6 hours has passed since the missed dose, skip dose and resume usual schedule the following day.

Tablets

Administer everolimus tablets (Afinitor, Zortress) orally once or twice daily.

In patients with renal or hepatic allografts, administer twice daily at the same time as cyclosporine or tacrolimus, respectively.

Swallow tablets whole with a glass of water; do not chew or crush.

Tablets for Oral Suspension

Administer everolimus tablets for oral suspension (Afinitor Disperz) once daily. Wear gloves when preparing suspension.

For administration using an oral syringe, place the prescribed dose (≤10 mg) in a 10-mL syringe; do not crush or break tablets. Draw approximately 5 mL of water and 4 mL of air into syringe; place syringe containing mixture in a container (tip up) for 3 minutes, until tablets are in suspension. Gently invert the syringe 5 times immediately prior to administration. Following administration, refill the syringe with 5 mL of water and 4 mL of air, swirl to suspend remaining particles, and administer entire contents of syringe. Prepare an additional syringe if a dose of >10 mg is required.

For administration using a small drinking glass, place the prescribed dose (≤10 mg) in a glass (size ≤100 mL) containing approximately 25 mL of water; do not crush or break tablets. Allow mixture to suspend for 3 minutes. Gently stir the mixture with a spoon immediately prior to administration. Following administration, add 25 mL of water to the glass and stir with the same spoon to resuspend the remaining particles, and swallow entire contents of the glass. Prepare an additional glass if a dose of >10 mg is required.

Therapeutic Drug Monitoring

Therapeutic Drug Monitoring and Dosage Adjustments in Pediatric and Adult Patients with SEGA and Partial-onset Seizures with TSC

Adjust dosage at 1–2 week intervals as needed to achieve and maintain trough whole blood everolimus concentrations of 5–15 ng/mL.

Higher trough concentrations may be associated with larger reductions in SEGA volume and a greater reduction in absolute seizure frequency.

Adjust dosage using this equation if trough concentrations are not within goal range of 5–15 ng/mL: New dosage = current dosage multiplied by (target trough concentration divided by current trough concentration.

For each dosage titration, increase dosage increment by no greater than 5 mg; multiple dosage titrations at 1–2 week intervals may be necessary to attain target trough concentrations.

Measure trough concentrations 2 weeks after any change in hepatic function, or during the initiation or discontinuance of a potent inducer or moderate inhibitor of CYP3A4 and P-glycoprotein.

Once a stable dosage is attained, monitor trough concentrations every 3–6 months in patients with changing body surface area and every 6–12 months in patients with stable body surface area for the duration of treatment.

Make dosage adjustments when used in conjunction with moderate inhibitors or potent inducers of CYP3A4 and inhibitors of P-glycoprotein.

Therapeutic Drug Monitoring and Dosage Adjustment of Everolimus in Renal Allotransplantation in Adults

Adjust dosage based on trough whole blood everolimus concentrations, tolerability, individual response, change in concomitant drug therapy, and clinical situation. May adjust maintenance dosage based on trough everolimus concentrations obtained 4–5 days after a previous dosage change in either everolimus or cyclosporine.

Titrate dosage to attain therapeutic trough everolimus concentrations of 3–8 ng/mL. In clinical trials, whole blood trough concentrations ≥3 ng/mL were associated with a lower incidence of treated biopsy-proven acute rejection. Similar efficacy and more adverse effects observed in patients with trough everolimus concentrations of 6–12 ng/mL compared with patients with trough concentrations of 3–8 ng/mL.

Recommended therapeutic range of 3–8 ng/mL is based on a liquid chromatography-tandem mass spectrometry (LC/MS/MS) assay method. May measure concentrations by chromatographic or immunoassay methodologies; however, the measured concentrations depend on the type of assay used, and individual patient sample concentration values from different assay methodologies may not be interchangeable. Consider assay results with knowledge of the specific assay used.13, Maintaining communication with the laboratory performing the assay is essential.

Therapeutic Drug Monitoring and Dosage Adjustment of Cyclosporine with Everolimus in Renal Allotransplantation in Adults

Reduce cyclosporine dosage and target therapeutic range when used in combination with everolimus to minimize risk of nephrotoxicity.

Adjust cyclosporine dosage based on whole blood trough concentrations. The recommended therapeutic ranges for cyclosporine are 100–200 ng/mL through month 1 posttransplant, 75–150 ng/mL at months 2 and 3, 50–100 ng/mL at month 4, and 25–50 ng/mL from month 6 through month 12.

Administer cyclosporine (USP modified) as oral capsules twice daily unless administration of oral solution or IV cyclosporine cannot be avoided. Everolimus has not been evaluated in clinical trials with other formulations of cyclosporine.

Initiate cyclosporine as soon as possible and no later than 48 hours after reperfusion of the graft, and adjust the dosage to target concentrations from day 5 onward. Adjust the treatment regimen if progressive impairment of renal function occurs.

Data regarding everolimus dosages with reduced trough cyclosporine concentrations of 25–50 ng/mL after 12 months are limited.

Prior to dosage reduction of cyclosporine, verify steady-state whole blood trough everolimus concentrations of ≥3 ng/mL. Everolimus concentrations may decrease if cyclosporine exposure is reduced.

Therapeutic Drug Monitoring and Dosage Adjustment of Everolimus in Hepatic Allotransplantation in Adults

Adjust dosage based on trough whole blood everolimus concentrations, tolerability, individual response, change in concomitant drug therapy, and clinical situation. May adjust maintenance dosage based on trough everolimus concentrations obtained 4–5 days after a previous dosage change.

Titrate dosage to attain therapeutic trough everolimus concentrations of 3–8 ng/mL. In clinical trials, whole blood trough concentrations ≥3 ng/mL were associated with a lower incidence of treated biopsy-proven acute rejection. Similar efficacy and more adverse effects observed in patients with trough everolimus concentrations of 6–12 ng/mL compared with patients with trough concentrations of 3–8 ng/mL.

Therapeutic Drug Monitoring and Dosage Adjustment of Tacrolimus with Everolimus in Hepatic Allotransplantation in Adults

Reduce tacrolimus dosage and target therapeutic range when used in combination with everolimus to minimize risk of nephrotoxicity.

Adjust tacrolimus dosage based on whole blood trough concentrations. Recommended therapeutic range for tacrolimus is 3–5 ng/mL by 3 weeks after the first dose of everolimus (approximately month 2 posttransplant) through month 12 posttransplant.

Administer tacrolimus as oral capsules twice daily unless administration of IV tacrolimus cannot be avoided.

Data regarding everolimus dosages with reduced trough tacrolimus concentrations of 3–5 ng/mL after 12 months are limited. Prior to dosage reduction of tacrolimus, verify steady-state whole blood trough everolimus concentrations of ≥3 ng/mL.

Tacrolimus does not affect everolimus concentrations.

Dosage Modifications for Toxicity

Adjustment of everolimus dosage and/or interruption of therapy may be required for patients with breast cancer, NET, renal cell carcinoma, or TSC-associated renal angiomyolipoma, SEGA, or partial-onset seizures, according to the toxicity. If dosage reduction is required, the suggested dosage is approximately 50% lower than the previously administered daily dosage, if dosage reduction is required. Everolimus may be changed to every other day dosing if the reduced dose is lower than the lowest available strength.

Cautions for Everolimus

Contraindications

Warnings/Precautions

Warnings

Management of Immunosuppression

The manufacturer of everolimus (Zortress) states that the drug should be used only by clinicians experienced in immunosuppressive therapy and the management of transplant patients. (See Boxed Warning.)

Malignancies and Serious Infections

Immunosuppressants, including everolimus, can increase susceptibility to infection (bacterial, fungal, viral, or protozoal infections, including opportunistic infections) (see Boxed Warning). Severe or fatal localized and systemic infections reported.

Antimicrobial prophylaxis for Pneumocystis jiroveci (formerly Pneumocystis carinii) pneumonia (PJP) and cytomegalovirus (CMV) is recommended in transplant recipients. The manufacturer of Afinitor and Afinitor Disperz recommends administration of prophylaxis against PJP when concomitant corticosteroids or immunosuppressives are used with everolimus.

Monitor for signs and symptoms of infection and institute appropriate treatment if infection develops; consider interruption or discontinuance of everolimus therapy. Complete treatment of a preexisting invasive fungal infection prior to initiating everolimus therapy.

Immunosuppressants, including everolimus, may increase risk of development of lymphomas or other malignancies, particularly of the skin. Risk appears to be related to intensity and duration of immunosuppression rather than to the use of any specific drug. In patients with an increased risk for skin cancer, limit exposure to sunlight and ultraviolet light with use of protective clothing and sunscreen with a high protection factor.

Kidney Graft Thrombosis

Increased risk of kidney arterial and venous thrombosis, resulting in kidney graft loss; occurs primarily within the first 30 days after renal transplantation (see Boxed Warning).

Renal Effects

Increased risk of nephrotoxicity when used concurrently with standard cyclosporine dosages; use reduced cyclosporine dosages (see Boxed Warning). Not studied with standard tacrolimus dosages in hepatic transplant recipients; use in combination with reduced-dosage tacrolimus to minimize potential risk of nephrotoxicity.

Increased risk of proteinuria reported in transplant patients receiving everolimus (Zortress); higher risk observed in patients with higher whole blood trough concentrations of the drug. Monitor transplant patients for proteinuria.

Monitor renal function in all transplant patients. Consider switching to other immunosuppressive therapies if renal function does not improve after dosage adjustments or if renal dysfunction is thought to be drug related.

Increases in Scr and proteinuria reported in patients receiving everolimus (Afinitor and Afinitor Disperz). Cases of renal failure (including acute renal failure), some with fatal outcome, also observed. Monitor renal function prior to initiating everolimus and annually thereafter. In patients with increased risk factors for renal dysfunction, monitor renal function at least every 6 months.

Increased Mortality in Cardiac Transplantation

Increased mortality within the first 3 months posttransplantation observed in de novo cardiac transplant patients receiving everolimus (Zortress) in an immunosuppressive regimen with or without induction therapy in a clinical trial; use not recommended in cardiac transplantation (see Boxed Warning.).

Other Warnings/Precautions

Interstitial Lung Disease/Noninfectious Pneumonitis

Potentially severe or fatal noninfectious pneumonitis reported.

Consider diagnosis of noninfectious pneumonitis in patients presenting with nonspecific respiratory signs and symptoms (e.g., hypoxia, pleural effusion, cough, dyspnea), as well as the presence of opportunistic infections such as PJP. Administer prophylaxis against PJP when corticosteroids and other immunosuppressive treatments are required.

If radiological changes suggestive of noninfectious pneumonitis develop in patients with minimal or no symptoms, continue Afinitor and Afinitor Disperz without dosage alteration. If grade 2–4 symptoms of noninfectious pneumonitis develop, interruption or discontinuance of therapy and subsequent dosage reduction may be required.

In renal transplant patients, noninfectious pneumonitis may respond to interruption of everolimus therapy with or without glucocorticoid therapy.

Consider diagnosis of interstitial lung disease in patients presenting with symptoms consistent with infectious pneumonia but not responding to antibiotic therapy and in whom other causes (e.g., infection, cancer, other non-drug causes) have been excluded. In renal or hepatic transplant patients, interstitial lung disease generally resolves following interruption of everolimus therapy with or without glucocorticoid therapy; however, fatal cases reported.

Stomatitis

Mouth ulcers, stomatitis, and oral mucositis, mostly grade 1 and 2, reported. Stomatitis generally occurs within the first 8 weeks of starting treatment.

Topical therapy recommended if oral ulceration occurs. Initiation of dexamethasone 0.1 mg/mL alcohol-free oral solution as a mouthwash when starting everolimus has been shown to reduce the incidence and severity of stomatitis in adult patients.

Avoid alcohol-, peroxide-, iodine-, or thyme-containing mouthwashes because they may exacerbate the condition.

Do not use antifungal agents unless fungal infection has been diagnosed.

Depending on severity, interruption of therapy, dosage reduction, and/or drug discontinuance may be required.

Hepatic Artery Thrombosis (HAT)

Mammanlian target of rapmaycin (mTOR) inhibitors are associated with an increased risk of HAT. Most cases occurred within the first 30 days posttransplant and most resulted in graft loss or death. Do not administer everolimus earlier than 30 days after liver transplantation.

Polyoma Virus Infections

Increased risk of reactivation of latent viral infections, including polyoma virus infections. Polyoma virus infections in transplant recipients may be serious or fatal; these include polyoma virus-associated neuropathy (PVAN), mostly due to BK virus infection, and JC virus-associated progressive multiple leukoencephalopathy (PML). PVAN may result in deteriorating renal function and renal graft loss.

Monitoring transplant patients may help detect patients at risk of PVAN. Consider reduction in total immunosuppression in patients who develop evidence of PVAN or PML. Also consider risk that reduced immunosuppression represents to the functioning allograft.

Risk of Infection or Reduced Immune Response with Immunization

Avoid use of live vaccines and close contact with individuals who have received live vaccines.

Consider the timing of routine vaccinations in pediatric patients who do not require immediate treatment before initiating everolimus therapy. Prior to initiation of everolimus therapy, complete the recommended childhood series ofvaccinations according to the US Public Health Service Advisory Committee on Immunization Practices (ACIP) guidelines. An accelerated vaccination schedule may be appropriate.

Severe Hypersensitivity Reactions

Hypersensitivity reactions, including anaphylaxis, dyspnea, flushing, chest pain, and/or angioedema, reported with everolimus and other rapamycin derivatives. Permanently discontinue everolimus if clinically significant hypersensitivity reactions develop.

Angioedema

Angioedema reported with everolimus and other mTOR inhibitors. Concomitant use of other drugs known to cause angioedema (e.g., ACE inhibitors) may increase this risk. Monitor patients for possible symptoms; if angioedema occurs, treat promptly. The manufacturer recommends permanent discontinuation of Afinitor and Afinitor Disperz if angioedema occurs.

Wound Healing and Fluid Accumulation

Increased risk of delayed wound healing and increased incidence of wound-related complications, including wound dehiscence, wound infection, incisional hernia, lymphocele, and seroma, reported; wound-related complications may require surgical treatment.

Generalized fluid accumulation, including peripheral edema (e.g., lymphedema), and other types of localized fluid accumulation (e.g., pericardial and pleural effusions, ascites) also reported.

Monitor patients for delayed wound healing and fluid accumulation; if present, treat promptly to minimize potential complications.

The manufacturer of Afinitor and Afinitor Disperz recommends withholding everolimus for at least 1 week prior to elective surgery, and for at least 2 weeks after completion of the procedure until adequate wound healing has been established. Safety of resuming everolimus following the resolution of wound healing complications is not known.

Metabolic Disorders

Hyperglycemia, hypercholesterolemia, and hypertriglyceridemia reported.

Following transplantation, increased risk of developing new-onset diabetes mellitus reported.

Closely monitor glucose concentrations in patients receiving everolimus (Zortress) following renal and hepatic allotransplantation. Monitor fasting glucose concentrations prior to and annually periodically during everolimus (Afinitor and Afinitor Disperz) therapy; when possible, achieve optimal glycemic control prior to initiation of everolimus. In diabetic patients, monitor fasting blood glucose more frequently as clinically indicated.

Monitor fasting serum lipids prior to and periodically during everolimus (Afinitor, Zortress) therapy (annually for patients receiving Afinitor and Afinitor Disperz). When possible, achieve optimal lipid control prior to initiation of therapy. Treat patients who develop hyperlipidemia while receiving everolimus according to current standards of care.

Normalization of serum lipids with antihyperlipidemic agents may not be possible in patients receiving everolimus (Zortress). Consider the risk/benefit of everolimus therapy prior to initiating therapy in patients with baseline hyperlipidemia and of continued therapy in patients who develop severe refractory hyperlipidemia while receiving the drug. Safety and efficacy of everolimus in patients with baseline cholesterol concentrations >350 mg/dL not established.

Depending on severity of metabolic disorders, interruption of Afinitor or Afinitor Disperz therapy, dosage reduction, and/or drug discontinuance may be required.

Patients with Hereditary Disorders

Everolimus may cause diarrhea and malabsorption in patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption; avoid use in such patients.

Myelosuppression

Anemia, lymphopenia, neutropenia, and thrombocytopenia reported. Monitor CBC prior to and every 6 months during the first year of therapy. Thereafter, CBC can be monitored annually. Depending on severity, interruption of therapy, dosage reduction, and/or drug discontinuance may be required.

Increased Risk of Thrombotic Microangiopathy (TMA)/Thrombotic Thrombocytopenic Purpura (TTP)/Hemolytic Uremic Syndrome (HUS)

Concurrent use of everolimus and cyclosporine may increase the risk of TMA/TTP/HUS. Monitor hematologic parameters in patients concurrently receiving everolimus and cyclosporine.

Radiation Sensitization and Recall

Radiation sensitization and recall involving cutaneous and visceral organs (including radiation esophagitis and pneumonitis), including some severe cases, have been reported in patients receiving radiation prior to, during, and after initiation of everolimus (Afinitor and Afinitor Disperz). Monitor patients closely if everolimus is administered during or in sequence with radiation therapy.

Interaction with Potent Inhibitors and Inducers of Cytochrome P-450 Isoenzyme 3A4

Concomitant use of everolimus (Zortress) with strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, voriconazole, clarithromycin, ritonavir) and strong inducers of CYP3A4 (e.g., rifampin, rifabutin) is not recommended or requires close monitoring of whole blood trough everolimus concentrations and/or adjustment of everolimus dosage.

Fetal/Neonatal Morbidity and Mortality

Can cause fetal harm; teratogenicity and embryolethality demonstrated in animals. No adequate and well-controlled studies in humans.

Females of childbearing potential should use an effective method of contraception during and for up to 8 weeks following discontinuance of everolimus.

Advise male partners of such females to use effective contraception during everolimus treatment, and for 4 weeks after discontinuance of the drug.

If used during pregnancy or if patient becomes pregnant, apprise of potential fetal hazard.

Impairment of Male Fertility

Possible impairment of male fertility (decreased fertility observed in male rats); azoospermia or oligospermia may be observed.

Drug Interactions

Closely monitor for an increase in everolimus blood levels and for adverse reactions suggestive of everolimus toxicity when cannabidiol is administered concurrently with everolimus (Zortress). A dose reduction of everolimus (Zortress) should be considered as needed when coadministration occurs.

Grapefruit and grapefruit juice inhibit cytochrome CYP3A4 and P-gp activity and should therefore be avoided with concomitant use of everolimus.

Specific Populations

Pregnancy

Based on animal studies and the mechanism of action of everolimus, may cause fetal harm. Verify pregnancy status of females of reproductive potential prior to initiation.

Women of childbearing potential should use effective contraception during and for up to 8 weeks after discontinuance of therapy.

National Transplantation Pregnancy Registry (NTPR) at 877-955-6877 or [Web] .

Lactation

Everolimus and/or its metabolites distribute into milk in rats; not known whether distributed into human milk.

Avoid breast-feeding. Some manufacturers state to avoid breastfeeding during treatment with everolimus and for 2 weeks following the last dose.

Females and Males of Reproductive Potential

Everolimus may impair male and female fertility.

Confirm pregnancy status prior to initiation of everolimus.

Advise females of reproductive potential to use effective contraceptive methods during everolimus therapy and for up to 8 weeks after discontinuance of the drug. Advise males who are partners of such females to use effective methods of contraception while receiving the drug and for at least 4 weeks after discontinuing therapy.

Pediatric Use

Safety and efficacy for treatment of SEGA with TSC have been evaluated in pediatric patients ≥1 year of age. Safety and efficacy not established in children <1 year of age with SEGA and TSC. Although it remains inconclusive, the use of everolimus does not appear to adversely affect growth and pubertal development.

Safety and efficacy for the adjunctive treatment of partial-onset seizures with TSC have been evaluated in pediatric patients ≥2 years of age. Safety and efficacy not established in pediatric patients < 2 years of age with TSC-associated partial-onset seizures.

Incidence of infections, including serious infections, in pediatric patients <6 years of age reported at a higher frequency in comparison to patients ≥6 years of age.

Safety and efficacy for treatment of renal angiomyolipoma with TSC in the absence of SEGA, hormone-receptor positive, HER2-negative breast cancer, NET, and renal cell carcinoma not established in pediatric patients.

Safety and efficacy for prevention of renal or hepatic allograft rejection not established in pediatric patients <18 years of age.

Geriatric Use

Patients with breast cancer, advanced renal cell carcinoma, or advanced PNET: No substantial differences in safety and efficacy relative to younger adults, but increased sensitivity cannot be ruled out.

Transplant recipients: Limited clinical experience with use of everolimus following transplantation in patients ≥65 years of age.

Hepatic Impairment

Drug Interactions

Metabolized principally by CYP3A4; competitive inhibitor of CYP3A4 and CYP2D6 in vitro. Also a substrate of the efflux transporter P-glycoprotein (P-gp).

Inhibitors or Inducers of CYP3A4 and P-gp

P-gp and strong CYP3A4 inhibitors: Avoid concomitant use.

P-gp and moderate CYP3A4 inhibitors: Reduced everolimus dosage required in patients who require coadministration. If concomitant use is required in patients with breast cancer, neuroendocrine tumors (NET), renal cell carcinoma, or tuberous sclerosis complex (TSC)-associated renal angiomyolipoma, reduce dosage to 2.5 mg; may increase if tolerated to 5 mg daily. Resume original everolimus dosage 3 days after discontinuance of the P-gp and CYP inhibitor. If concomitant use is required in patients with TSC-associated subependymal giant cell astrocytoma (SEGA) or partial-onset seizures, reduce the initial daily dosage by 50%; subsequent dosing based on therapeutic drug monitoring. Resume original everolimus dosage 3 days after discontinuance of the P-gp and CYP inhibitor and reassess trough concentration 2 weeks later.

P-gp and strong CYP3A4 inducers: Avoid concomitant use. If concomitant use cannot be avoided in patients with breast cancer, NET, renal cell carcinoma, or TSC-associated renal angiomyolipoma, double the daily dosage (from 10 mg daily up to 20 mg daily, titrated in ≤5 mg increments). Resume original everolimus dosage 5 days after discontinuance of the P-gp and potent CYP3A4 inducer.

If concomitant use cannot be avoided in patients with TSC-associated SEGA or partial-onset seizures, double the dosage of everolimus, titrating in ≤5-mg increments. Assess trough concentrations 2 weeks after doubling the dosage, and adjust as necessary for a trough concentration of 5–15 ng/mL. If a second potent CYP3A4 inducer is added to the existing regimen and the dosage has already been adjusted, additional dosage modification may not be necessary. Resume original everolimus dosage 5 days after discontinuance of the P-gp and potent inducer and reassess everolimus trough concentrations 2 weeks later.

Drugs Metabolized by Hepatic Microsomal Enzymes

Substrates of CYP3A4 and CYP2D6: Potential pharmacokinetic interaction (increased plasma substrate concentrations). Use with caution in patients receiving CYP3A4 or CYP2D6 substrates.

Nephrotoxic Agents

Potential for increased risk of nephrotoxicity with concomitant cyclosporine therapy in renal transplant patients. Use other drugs known to impair renal function concomitantly with caution.

Everolimus Pharmacokinetics

Absorption

Bioavailability

Peak everolimus concentrations attained within 1–2 hours following oral administration of doses ranging from 5–70 mg in patients with advanced solid tumors.

Increases in peak plasma concentrations dose-proportional following single doses of 5–10 mg. Peak plasma concentrations and AUC also dose-proportional at steady state following oral dosages of 0.5–2 mg twice daily in renal allograft patients. Increases in peak plasma concentrations less than dose-proportional following single doses of ≥20 mg; considered unlikely to be clinically important. Increases in AUC dose-proportional over dosage range of 5–70 mg.

AUC of everolimus tablets for oral suspension (Afinitor Disperz) was equivalent to that of everolimus tablets (Afinitor); peak concentrations were 20–36% lower for everolimus tablets for oral suspension. Predicted trough concentrations at steady state were similar between these dosage forms following daily administration.

In patients with advanced solid tumors, steady-state concentrations achieved within 2 weeks of once-daily dosing. In renal allograft patients, steady-state concentrations achieved by day 4 with an accumulation in blood concentrations of twofold to threefold compared with exposure following the first dose.

In patients with SEGA and TSC, everolimus trough concentrations were dose-proportional at daily dosages of 1.35–14.4 mg/m2.

Food

Administration of 10-mg tablet with a high-fat meal in healthy individuals reduced peak plasma concentrations and AUC of everolimus by 54 and 22%, respectively; light fat meals reduced peak plasma concentrations and AUC of everolimus by 42 and 32%, respectively. However, food had no apparent effect on the postabsorption phase concentration-time profile.

Administration of 9-mg tablets for oral suspension with a high-fat in healthy individuals reduced everolimus peak plasma concentrations and AUC by 60 and 12%, respectively; administration with a low-fat meal reduced peak plasma concentrations and AUC by 50 and 30%, respectively.

Special Populations

Mild, moderate, and severe hepatic impairment increased AUC by 1.8-, 3.2-, and 3.6-fold, respectively, in a single-dose study. In another study, average AUC in individuals with moderate hepatic impairment was twice that found in those with normal hepatic function.

Distribution

Extent

Crosses the placenta. Everolimus and/or its metabolites readily distributed into milk in rats at a concentration 3.5 times higher than in maternal serum.

Plasma Protein Binding

Approximately 74%.

Special Populations

Moderate hepatic impairment does not alter plasma protein binding.

Elimination

Metabolism

Metabolized by CYP3A4 to inactive metabolites; also a substrate for P-glycoprotein.

Elimination Route

Excreted in feces (80%) and urine (5%) as inactive metabolites.

Half-life

Approximately 30 hours.

Special Populations

No significant correlation between Clcr (range: 25–178 mL/minute) and everolimus clearance; renal impairment not expected to influence drug exposure.

In patients with SEGA, everolimus clearance normalized to body surface area may be higher in pediatric patients compared with adults.

Higher exposure to everolimus among Japanese patients compared with non-Japanese patients; relevance to safety and efficacy not established.

Clearance is 20% higher in black patients than in Caucasian patients; relevance to safety and efficacy not established.

In patients with cancer, no apparent relationship observed between oral clearance and age or sex.

Stability

Storage

Oral

Tablets

Original container at 25°C (may be exposed to 15–30°C); protect from light and moisture.

Tablets for Oral Suspension
