Increased susceptibility to infection and the possible development of malignancies such as lymphoma and skin cancer may result from immunosuppression.
Only health care providers experienced in immunosuppressive therapy and management of transplant patients should prescribe everolimus. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The health care provider responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.
An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days post-transplantation.
Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with everolimus. Therefore, use reduced doses of cyclosporine should be used in combination with everolimus in order to reduce kidney dysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations.
Increased mortality, often associated with serious infection, within the first 3 months of 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.
Note: Tablets (Afinitor, Zortress) and tablets for oral suspension (Afinitor Disperz) are not interchangeable; Afinitor Disperz is only indicated for the treatment of tuberous sclerosis complex (TSC)–associated partial-onset seizures and TSC-associated subependymal giant cell astrocytoma (SEGA), in conjunction with therapeutic monitoring. Do not combine formulations to achieve total desired dose. If possible, optimize glucose control and lipids prior to treatment initiation.
Prophylaxis: Antimicrobial prophylaxis for Pneumocystis jirovecii pneumonia (PJP) and prophylaxis for cytomegalovirus (CMV) is recommended in transplant recipients. When concomitant corticosteroids or other immunosuppressive agents are required, administer PJP prophylaxis. Treatment of preexisting invasive fungal infections should be completed prior to starting everolimus treatment.

Transplantation, renal:
Evidence of polyoma virus infection or PML: Consider reduced immunosuppression (taking into account the allograft risks associated with decreased immunosuppression).
Interstitial lung disease/noninfectious pneumonitis: Most cases resolve with treatment interruption (with or without corticosteroids).
All patients: No adjustment necessary at baseline; nephrotoxicity has been reported with use; monitor renal function.
Tuberous sclerosis complex (TSC)-associated subependymal giant cell astrocytoma (SEGA) or partial-onset seizures:
Afinitor, Afinitor Disperz: Children and Adolescents:
Mild to moderate hepatic impairment: There is no initial dosage adjustment provided in the manufacturer's labeling; subsequent dosing should be based on therapeutic drug monitoring (monitor serum drug concentration 2 weeks after initiation, dosage modifications, or after any change in hepatic status; target trough concentration: 5 to 15 ng/mL).
Severe hepatic impairment: Reduce initial dose to 2.5 mg/m2 once daily; subsequent dosing is based on therapeutic drug monitoring (monitor 2 weeks after initiation, dosage modifications, or after any change in hepatic status; target trough concentration: 5 to 15 ng/mL).
Angioedema (eg, lingual) following initiation of everolimus has been reported. Angioedema is limited to case reports in the oncology literature (Ref). Angioedema may respond to hypersensitivity treatment (eg, corticosteroids, antihistamines) and mechanistic target of rapamycin (mTOR) inhibitor discontinuation (Ref).
Mechanism: Non–dose-related; immunologic; alteration in the bradykinin pathway and impaired endothelial response to bradykinin (Ref).
Onset: Varied. In solid organ transplant, angioedema presented between 2 to 60 days after initiation of everolimus (Ref); similar varied onset observed in patients receiving everolimus for treatment of a malignancy (mean: 21 days to 1 month after initiation) (Ref).
Risk factors:
• Concurrent administration of angiotensin converting enzyme inhibitors (ACEIs) (Ref)
• History of angioedema with ACEIs (Ref)
Everolimus-associated edema can manifest in several ways, including peripheral edema, eyelid edema, lymphocele, or effusions (Ref).
Mechanism: Non–dose-related; several pathways of altered lymphatic drainage have been hypothesized, specifically endothelial dysfunction through activation of protein kinase C-α; reduced vascular endothelial growth factor expression and interruption of vascular endothelial p120-cadherin leading to increased capillary permeability; and alterations in endothelial cells involved in lymphatic drainage mediated through the mTOR pathway (Ref).
Onset: Varied. In a review of solid organ transplant recipients, edema presented between 1 day to 3 years after initiation (Ref); similar varied onset was observed in solid tumors (eg, breast cancer) with a mean of 12 months after initiation (Ref).
Risk factors:
Solid organ transplant recipients:
• Glomerular filtration rate <35 mL/minute (Ref)
• History of acute rejection (Ref)
• Dose, exposure-related (Ref)
• Concurrent administration of dihydropyridine calcium channel blockers (Ref)
• High salt diet (Ref)
Everolimus is associated with several endocrine and metabolic-related effects, including:
• Hyperglycemia: Reported in various studies (Ref).
• Acute pancreatitis: Case reports in the setting of solid tumor treatment (Ref).
• Ketoacidosis: Reported in the setting of oncologic indications (Ref).
• Hypertriglyceridemia: Reported in malignancy (Ref) and solid organ transplant (Ref).
• Hypercholesterolemia: Increased cholesterol requiring intervention has been reported (Ref).
Mechanism: Dose-related; related to pharmacologic action. Everolimus has been shown to decrease β-cell mass and function and increase glycogen turnover which may reduce endogenous insulin secretion and promote insulin resistance yielding hyperglycemia (Ref). The mechanism for everolimus-induced hyperlipidemia and increased triglycerides is unknown but may be related to reduced clearance of lipids, specifically apolipoproteins (eg, B100) generated in the liver (Ref).
Onset: Varied. Hyperglycemia has been reported 3 to 8 weeks after exposure in cancer patients (Ref); hyperglycemia onset in solid organ transplant recipients is difficult to decipher in the setting of concurrent immunosuppressants which also cause hyperglycemia (Ref). Cholesterol and triglycerides have been reported to increase within 4 weeks of exposure in oncology patients (Ref) and 2 to 3 months in solid organ transplant recipients (Ref). Acute pancreatitis occurred within 2 months after initiation of therapy in case reports (Ref).
Risk factors:
• Concurrent use of tacrolimus or corticosteroids increases risk of hyperglycemia specifically in solid organ transplant recipients (Ref)
• Dose-related; increased exposure increases the risk of development of endocrine-associated complications (Ref)
• High triglyceride levels ≥500 mg/dL increases risk of acute pancreatitis (Ref)
• Preexisting dysfunction in glucose metabolism, diabetes, or diabetes risk factors (Ref)
• Preexisting hyperlipidemia (Ref)
• Tumor type (eg, renal cell carcinoma, neuroendocrine tumors) (Ref)
• Viral infections (eg, cytomegalovirus, hepatitis C virus) (Ref)
Everolimus exposure can cause anemia, thrombocytopenia, leukopenia, and lymphocytopenia, which may resolve upon discontinuation of therapy (Ref). The incidence of everolimus-related hematologic abnormalities in patients with cancer appear to be more prevalent than in solid organ transplant recipients; this difference may be dose-related (Ref).
Mechanism: Dose- and time-related; related to cumulative dose; mechanistic target of rapamycin (mTOR) inhibitors block the cell cycle and decrease interleukin-2 receptor and co-stimulatory pathways which may also be important for hematopoietic cell proliferation (Ref). mTOR inhibitor-related anemia may also result from decreased iron absorption from the gastrointestinal tract and alteration in iron uptake into erythrocytes (Ref).
Onset: Varied. Changes in hematologic parameters occurred as early as 2 weeks in oncology patients and solid organ transplant recipients (Ref).
Risk factors:
mTOR inhibitor-related anemia in solid organ transplant:
• Dose-related, resolution upon discontinuation (Ref)
• Increased age (Ref)
• Low iron (Ref)
• Concurrent malignancy (Ref)
• Presence of inflammation (Ref)
• Kidney insufficiency (Ref)
• Concurrent viral infection (Ref)
• Concurrent use of mycophenolate (Ref)
Non-oliguric kidney damage requiring dialysis and nephrotic syndrome have been reported in patients with cancer with resolution after cessation of everolimus (Ref). Glomerulonephritis in a kidney transplant recipient presenting as proteinuria has also been reported (Ref). Mild to moderate proteinuria was reported in patients with renal cell carcinoma receiving everolimus as first-line therapy in one retrospective review; median time to resolution of proteinuria in this population was 2 months (range: 1 to 12 months) (Ref).
Mechanism: Dose-related; related to the pharmacologic action; may be related to everolimus accumulation in kidney cells; however, the exact mechanism is unknown but proposed loss of podocyte integrity or kidney epithelial cell apoptosis through immunologic pathways (Ref). In solid organ transplant recipients transitioned from a calcineurin inhibitor to everolimus, proteinuria may be related to alterations in glomerular permeability to serum proteins by increased blood flow and glomerular pressure after withdrawal of the calcineurin inhibitor (Ref).
Onset: Varied. Changes in kidney function were observed between 2 weeks to 5 years after initiation (Ref); in renal cell carcinoma, the median time to onset of proteinuria was 2 months (range: 1 to 15 months) (Ref).
Risk factors:
• Dose-related, higher trough concentrations (eg, >8 ng/mL) in solid organ transplant (Ref)
• Pretreatment proteinuria (>800 mg/day) (Ref)
• Preexisting kidney insufficiency (eg, eGFR <40 mL/minute) (Ref)
• Active viral infection (Ref)
• Diabetes (Ref)
Everolimus-induced non-infective pneumonitis is a diagnosis of exclusion (Ref). Patients may present with cough, shortness of breath, fever, malaise, or chest radiograph findings consistent with pneumonitis (Ref). Rate and degree of reduced lung diffusion capacity for carbon monoxide (corrected for hemoglobin) was shown to predict the severity of interstitial lung disease (ILD) in a pilot study and discriminate ILD from other underlying pulmonary disorders (Ref). The onset of symptoms correlates with recent exposure to everolimus and symptoms resolve with cessation of everolimus (Ref). Of note, in a single center experience, radiographic findings (18F-fluoro-deoxy-glucose combined with positron emission tomography/computerized tomography [18F-FDG PET/CT] imaging) of hypermetabolic pulmonary pleuroparenchymal anomalies were observed in most patients with metastatic breast cancer receiving everolimus (Ref).
Mechanism: Non–dose-related; immunologic; evidence of high number of CD4+ cells and eosinophils on bronchial alveolar lavage (Ref) and direct mTOR inhibitor toxicity to lung tissue (Ref).
Onset: Varied. Respiratory symptoms occurred as early as 5 days after initiation up to 6 years postexposure (Ref).
Risk factors:
• Asian heritage; Japanese heritage (Ref)
• Dose-related (increased exposure increases the risk of development of pneumonitis, although not confirmed) (Ref)
• Increased weight (Ref)
• Kidney insufficiency (Ref)
Radiation recall phenomenon has been reported in patients who previously underwent radiation therapy and subsequently received everolimus as part of their cancer treatment regimen (Ref). Specifically, case reports identify recall syndrome involving nonspecific inflammation (eg, pulmonary infiltrates, gastric ulcers, tissue erosion, esophagitis) in areas of radiation exposure after receiving everolimus (Ref). Resolution of symptoms occurred after cessation of therapy and appropriate supportive care (eg, corticosteroids) (Ref).
Mechanism: Non–dose-related; idiosyncratic; may be related to mechanistic target of rapamycin inhibition of DNA repair and angiogenesis (Ref).
Onset: Varied. Case reports identify symptoms as early as 1 week after initiating therapy and up to 16 weeks postexposure (Ref).
Risk factors:
• Previous or concurrent radiation exposure (Ref)
Mechanistic target of rapamycin (mTOR) inhibitor-associated stomatitis lesions are superficial, well-demarcated, singular or multiple ulcers that present with regular, round boarders in the mouth and generally occur on nonkeratinized areas (eg, inside of the lips, cheeks, tongue, soft palate) (Ref). Lesions are typically ≤0.5 cm in diameter (Ref). Most cases are mild to moderate in severity (Ref). Pain and impaired oral function can be dose-limiting (Ref). Therapy interruption or discontinuation was required to allow lesions to heal (Ref).
Mechanism: Dose-related; related to the pharmacologic action; may be related to composition of normal oral flora (eg, Bacteroidales species), genetic predisposition coding for proinflammatory cytokines (eg, serotonin transcriptase), or direct mTOR inhibitor toxicity to oral mucosa (Ref).
Onset: Intermediate; mTOR inhibitor associated-stomatitis symptoms usually develop between 5 and 7 days after initiation of therapy (Ref).
Risk factors:
• Dose-related (Ref)
• Stress and anxiety (Ref)
• Nutritional deficiency (Ref)
• Hormonal alteration (Ref)
• Conversion to everolimus post-solid organ transplant from a calcineurin inhibitor (eg, tacrolimus, cyclosporine) (Ref)
Mechanistic target of rapamycin (mTOR) inhibitors may induce a procoagulant state in some patients, resulting in thromboembolic events (eg, pulmonary embolism, deep vein thrombosis, allograft thrombosis) (Ref). These events have been described most frequently in liver transplant recipients, but events have been reported in all solid organ transplant recipients (Ref). There are also reports of thromboembolic events in oncology uses; specifically, thromboembolic events that led to discontinuation occurred in ~5% of patients undergoing treatment with everolimus plus hormonal therapy (eg, tamoxifen) for breast cancer (Ref).
Mechanism: Non–dose related; prothrombotic; everolimus increases von Willebrand factor which is evidence of endothelial cell activation and platelet activation (Ref). Increases in thrombin formation and impairment in fibrinolysis both contribute to clot formation in the setting of everolimus (Ref). mTOR inhibition can also contribute to up regulation of tissue factor which can contributor to clot formation (Ref).
Onset: Varied. Thromboembolic events occurred at an average of 376 days (range: 123 to 1,034 days) after initiation of therapy (Ref).
Risk factors:
• History of thrombophilia (Ref)
• Use early post-liver transplant (<30 days) (Ref)
• Concurrent use of hormonal therapy (eg, tamoxifen) (Ref)
Mechanistic target of rapamycin (mTOR) inhibitor-related wound healing impairment complications can manifest in several ways, including surgical wound dehiscence, lymphoceles, wound infection, seroma, hematoma, effusions, incisional site discharge, primary nonclosure, or delayed healing (Ref). The definition of a wound healing impairment is not well defined; therefore, the true mTOR inhibitor-related incidence is unknown (Ref).
Mechanism: Dose-related; related to the pharmacologic action; mTOR inhibitors suppress fibroblast proliferation, neointimal hyperplasia, and angiogenesis, which all may lead to impaired wound healing (Ref).
Onset: Varied. The exact time to event is challenging to decipher as evaluation of a transplant procedure-related wound event is typically collated at specific times after a procedure (eg, 1 month, 12 months) and details of primary wound non-healing or a wound-related complication are based on symptom detection (eg, lymphocele) and varying definitions in the literature (Ref).
Risk factors:
• Dose-related; higher doses or increased systemic exposure as evidenced by high systemic levels suggest a higher frequency of wound healing complications, including those that required intervention, specifically in kidney transplant recipients (Ref)
• History of diabetes mellitus (Ref)
• Increased body mass index (≥30 kg/m2) (Ref)
• Increased age (Ref)
• High corticosteroid exposure (Ref)
• History of a left ventricular assist device in heart transplant recipients (Ref)
• Redo sternotomy in heart transplant recipients (Ref)
• Active bacterial or fungal infection (Ref)

Canadian labeling: Additional contraindications (not in the US labeling): Treatment of seizures (any type) in populations other than those with a definite tuberous sclerosis complex (TSC) diagnosis.
Concerns related to adverse effects:
• Angioedema: Everolimus is associated with the development of angioedema; concomitant use with other agents known to cause angioedema (eg, ACE inhibitors) may increase the risk.
• Bone marrow suppression: Decreases in hemoglobin, neutrophils, platelets, and lymphocytes have been reported, including grade 3 and 4 events.
• Edema: Generalized edema (including peripheral edema and lymphedema) and local fluid accumulation (eg, pericardial effusion, pleural effusion, ascites) may occur.
• Graft thrombosis: An increased risk of kidney arterial and venous thrombosis has been reported in kidney transplantation, generally within the first 30 days after transplant; may result in graft loss.
• Hepatic artery thrombosis: Mammalian target of rapamycin (mTOR) inhibitors are associated with an increase in hepatic artery thrombosis, most cases have been reported within 30 days after transplant and usually proceeded to graft loss or death. Do not use everolimus prior to 30 days post liver transplant.
• Hypersensitivity: Severe hypersensitivity reactions (anaphylaxis, dyspnea, flushing, chest pain, and angioedema) have been reported.
• Infections: Everolimus has immunosuppressant properties, which may result in increased susceptibility to infection. Everolimus may predispose patients to bacterial, fungal, viral, or protozoal infections, including opportunistic infections. Polyoma virus infection in transplant recipients may be serious and/or fatal. Polyoma virus-associated nephropathy (primarily due to BK virus), which may result in serious cases of deteriorating kidney function and kidney graft loss, has been observed with use in kidney transplantation. JC virus-associated progressive multiple leukoencephalopathy (PML) may also be associated with everolimus use in transplantation. Reduced immunosuppression (considering the risks of rejection) should be considered with evidence of polyoma virus infection or PML. Localized and systemic infections (including pneumonia, mycobacterial infections, other bacterial infections, invasive fungal infections [eg, aspergillosis, candidiasis, or Pneumocystis jirovecii pneumonia {PJP}] and viral infections [eg, hepatitis B reactivation]) have occurred. Grade 3 and 4 infections have been reported; some infections have been severe (eg, sepsis, septic shock, or resulting in multisystem organ failure) or fatal. Serious infections have been reported at a higher frequency in patients <6 years of age. Treatment of preexisting invasive fungal infections should be completed prior to starting everolimus treatment. Combination immunosuppressant therapy in solid organ transplantation should be used with caution due to the risk of over immunosuppression, which may lead to increased susceptibility to infection.
• Malignancy: Immunosuppressant use may result in the development of malignancy, including lymphoma and skin cancer. The risk is associated with treatment intensity and the duration of therapy. To minimize the risk for skin cancer, limit exposure to sunlight and ultraviolet light; wear protective clothing, and use effective sunscreen.
• Metabolic effects: Hyperglycemia, hyperlipidemia, and hypertriglyceridemia have been reported, including grade 3 and 4 events. Higher serum everolimus concentrations are associated with an increased risk for hyperlipidemia. Everolimus has not been studied in transplant recipients with baseline cholesterol >350 mg/dL. Increases in serum glucose are common; may alter insulin and/or oral hypoglycemic therapy requirements in patients with diabetes. The risk for new-onset diabetes is increased with everolimus use after transplantation. Antihyperlipidemic therapy may not normalize levels.
• Mucositis/stomatitis: Everolimus is commonly associated with mouth ulcers, mucositis, and stomatitis. Stomatitis typically occurs within the first 8 weeks of therapy. Due to the high potential for drug interactions, avoid the use of systemic antifungals unless fungal infection has been diagnosed.
• Nephrotoxicity: Elevations in serum creatinine (generally mild), kidney failure, and proteinuria have been observed with everolimus. Grade 3 and 4 serum creatinine elevations and proteinuria have been reported. Risk of nephrotoxicity may be increased when administered with calcineurin inhibitors (eg, cyclosporine, tacrolimus); dosage adjustment of calcineurin inhibitor is necessary. The risk of proteinuria is increased when everolimus is used in combination with cyclosporine, and with higher serum everolimus concentrations.
• Pulmonary toxicity: Noninfectious pneumonitis, interstitial lung disease (ILD), and/or noninfectious fibrosis have been observed with mTOR inhibitors, including everolimus; some cases were fatal. Promptly evaluate worsening respiratory symptoms. Cases of ILD have been reported with pulmonary hypertension (including pulmonary arterial hypertension) as a secondary event. Consider opportunistic infections such as PJP when evaluating clinical symptoms. Pneumonitis has been reported even at reduced everolimus doses.
• Radiation sensitization/recall: Radiation sensitization and recall (some cases may be severe or involve cutaneous and visceral organs [eg, radiation esophagitis, pneumonitis]) have been reported in patients treated with radiation prior to, during, or after treatment with everolimus.
• Wound healing impairment: Vascular endothelial growth factor receptor inhibitors are associated with impaired wound healing; therefore, everolimus may affect wound healing. The safety of resuming everolimus treatment after resolution of wound healing complications has not been established.
Disease-related concerns:
• Heart transplantation: Increased mortality (usually associated with infections) within the first 3 months after transplant was noted in a study of patients with de novo heart transplant receiving immunosuppressive regimens containing everolimus (with or without induction therapy). Use in heart transplantation is not recommended. The boxed warning in the labeling (Zortress) is based on severe infectious complications, rather than efficacy (reduction in the incidence of cardiac allograft vasculopathy). Despite labeled warnings for this off-label indication, some centers continue to use everolimus (with reduced calcineurin inhibitor exposure). However, everolimus initiation in heart transplantation is delayed until 3 to 6 months post-transplantation due to impaired wound healing and pericardial effusions early in the postoperative period (Andreassen 2014; Andreassen 2016; Hirt 2013; Hollis 2015; ISHLT [Velleca 2023]).
• Hereditary galactose intolerance: Avoid use in patients with galactose intolerance, congenital lactase deficiency, or glucose-galactose malabsorption; may result in diarrhea and malabsorption.
• Kidney impairment: An increased incidence of rash, infection and dose interruptions have been reported in patients with kidney insufficiency (CrCl ≤60 mL/minute) who received mTOR inhibitors for the treatment of renal cell carcinoma (Gupta 2011). Serum creatinine elevations and proteinuria have been reported.
• Transplantation (solid organ): Everolimus should only be used by physicians experienced in immunosuppressive therapy and management of transplant recipients. Adequate laboratory and supportive medical resources must be readily available.
Concurrent drug therapy issues:
• Calcineurin inhibitor (CNI) combination therapy: Due to the increased risk for nephrotoxicity in solid organ transplantation, avoid standard doses of CNI (cyclosporine or tacrolimus) in combination with everolimus; reduced CNI doses are recommended. Therapeutic monitoring of CNI and everolimus concentrations is recommended.
Dosage form specific issues:
• Tablet formulations: Tablets (Afinitor, Zortress) and tablets for oral suspension (Afinitor Disperz) are not interchangeable; Afinitor Disperz is only indicated in conjunction with therapeutic monitoring for the treatment of tuberous sclerosis complex-associated partial-onset seizures and SEGA. Do not combine formulations to achieve total desired dose.
Other warnings/precautions:
• Assay method: For indications requiring whole blood trough concentrations to determine dosage adjustments, a consistent method should be used; concentration values from different assay methods may not be interchangeable.
• Immunizations: Patients should not be immunized with live viral vaccines during or shortly after treatment and should avoid close contact with recently vaccinated (live vaccine) individuals. In pediatric patients, complete recommended series of live virus childhood vaccinations prior to everolimus treatment (if immediate everolimus treatment is not indicated); an accelerated vaccination schedule may be appropriate.

Everolimus may cause infertility. In females, menstrual irregularities, secondary amenorrhea, and increases in luteinizing hormone and follicle-stimulating hormone have occurred. Azoospermia and oligospermia have been observed in males.
Based on the mechanism of action and data from animal reproduction studies, in utero exposure to everolimus may cause fetal harm. Information related to the use of everolimus in pregnancy is limited (Yamamura 2017).
The Transplant Pregnancy Registry International (TPR) is a registry that follows pregnancies that occur in maternal transplant recipients or those fathered by male transplant recipients. The TPR encourages reporting of pregnancies following solid organ transplant by contacting them at 1-877-955-6877 or https://www.transplantpregnancyregistry.org.
Everolimus is present in breast milk (Kociszewska-Najman 2017).
Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer during therapy (Afinitor, Afinitor Disperz, Zortress) and for 2 weeks following the last dose (Afinitor, Afinitor Disperz).
Avoid grapefruit and grapefruit juice.
CBC with differential (baseline, every 6 months during the first year of treatment, and then annually thereafter); liver function (baseline and periodic); kidney function including serum creatinine, urinary protein, and BUN (baseline and annually; monitor kidney function every 6 months in patients with additional risk factors for kidney failure); fasting serum glucose (baseline and annually in nondiabetic patients and more frequently as indicated in patients with diabetes or if on concomitant medications affecting glucose), HbA1c, and lipid profile (baseline and annually thereafter). Evaluate pregnancy status prior to initiating therapy in patients who could become pregnant. Monitor for signs and symptoms of infection, noninfectious pneumonitis (promptly evaluate worsening respiratory symptoms), stomatitis, or secondary malignancy. Monitor closely for radiation recall when everolimus is administered concomitantly or sequentially with radiation treatment. Monitor adherence.
Solid organ transplantation: Monitor everolimus whole blood trough concentrations (based on an LC/MS/MS assay method), especially in patients with hepatic impairment, with concomitant CYP3A4 inhibitors and inducers or cannabidiol, and when cyclosporine or tacrolimus formulations or doses are changed; dosage adjustments should be made on trough concentrations obtained 4 to 5 days after a previous dosage adjustment; monitor cyclosporine or tacrolimus concentrations; monitor for proteinuria.
Tuberous sclerosis complex (TSC)-associated partial onset seizures and subependymal giant cell astrocytoma (SEGA): Monitor everolimus whole blood trough concentrations 1 to 2 weeks after treatment initiation, with dosage modification(s), or when changing dosage forms between tablets and tablets for oral suspension, 2 weeks after a change in hepatic function and initiation or discontinuation of concurrent CYP3A4/P-glycoprotein (P-gp) inhibitor/inducer therapy. Maintain trough concentrations between 5 and 15 ng/mL; once stable dose is attained and if body surface area (BSA) is stable throughout treatment, monitor trough concentrations every 6 to 12 months (monitor every 3 to 6 months if BSA is changing).
Patients with cancer: The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Recommended range for everolimus whole blood trough concentrations:
Liver and kidney transplantation: 3 to 8 ng/mL (based on an LC/MS/MS assay method).
Tuberous sclerosis complex-associated partial-onset seizures and subependymal giant cell astrocytoma (SEGA): 5 to 15 ng/mL. High concentrations may be associated with larger reductions in SEGA volumes, responses have been observed at concentrations as low as 5 ng/mL.
Heart transplantation (off-label use): 3 to 8 ng/mL with reduced dose calcineurin inhibitor (Eisen 2013; Hollis 2015; ISHLT [Velleca 2023]) or 6 to 10 ng/mL following calcineurin inhibitor withdrawal (Andreassen 2014; ISHLT [Velleca 2023]).
Lung transplantation (off-label use): 3 to 8 ng/mL with reduced dose cyclosporine (Glanville 2015; Strueber 2016).
Everolimus is a macrolide immunosuppressant and a mechanistic target of rapamycin (mTOR) inhibitor which has antiproliferative and antiangiogenic properties, and reduces lipoma volume in patients with angiomyolipoma. Reduces protein synthesis and cell proliferation by binding to the FK binding protein-12 (FKBP-12), an intracellular protein, to form a complex that inhibits activation of mTOR (mechanistic target of rapamycin) serine-threonine kinase activity. Also reduces angiogenesis by inhibiting vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF-1) expression. Angiomyolipomas may occur due to unregulated mTOR activity in TSC-associated renal angiomyolipoma (Budde 2012); everolimus reduces lipoma volume (Bissler 2013).
Absorption: Rapid (Kirchner 2004)
Distribution: Apparent Vd: 128 to 589 L (Zortress); volume of distribution in pediatric renal transplant recipients (3 to 16 years) lower than adults (Van Damme-Lombaerts 2002)
Protein binding: ~74% (Afinitor and Zortress)
Metabolism: Extensively metabolized in the liver via CYP3A4; forms 6 weak metabolites (Afinitor and Zortress)
Bioavailability:
Tablets: ~30% (Tabernero 2008 [Afinitor]); Systemic exposure reduced by 22% with a high-fat meal and by 32% with a light-fat meal (Afinitor); Systemic exposure reduced 16% with a high-fat meal (Zortress)
Tablets for suspension (Afinitor): AUC equivalent to tablets although peak concentrations are 20% to 36% lower; steady state concentrations are similar; Systemic exposure reduced by 12% with a high-fat meal and by 30% with a low-fat meal
Half-life elimination: ~30 hours (Afinitor and Zortress); in pediatric renal transplant recipients (3 to 16 years), half-life similar to adult data (Van Damme-Lombaerts 2002)
Time to peak, plasma: 1 to 2 hours (Afinitor and Zortress)
Excretion: Feces (80%, based on solid organ transplant studies); Urine (~5%, based on solid organ transplant studies); clearance in pediatric renal transplant recipients lower than adults possibly due to distributive differences (Van Damme-Lombaerts 2002)
Hepatic function impairment:
Afinitor, Afinitor Disperz: In one study, subjects with mild (Child-Turcotte-Pugh class A), moderate (Child-Turcotte-Pugh class B), and severe (Child-Turcotte-Pugh class C) impairment had a 1.8-fold, 3.2-fold, and 3.6-fold higher AUC, respectively, compared to patients with normal function. In another study, the average AUC in subjects with moderate (Child-Turcotte-Pugh class B) impairment was twice that of subjects with normal function.
Zortress: The average AUC in subjects with mild (Child-Turcotte-Pugh class A) impairment was 1.6-fold higher than that of patients with normal hepatic function (following a 10 mg dose); in moderate (Child-Turcotte-Pugh class B) impairment the AUC was 2.1- to 3.3-fold higher than that of patients with normal hepatic function (following a 2 mg or 10 mg dose); in severe (Child-Turcotte-Pugh class C) impairment the AUC was 3.6-fold higher than that of patients with normal hepatic function (following a 10 mg dose).
Pediatric: In patients with tuberous sclerosis complex (TSC)-associated subependymal giant cell astrocytoma (SEGA) or TSC-associated partial-onset seizures, mean serum Cmin values when normalized to mg/m2 dose in pediatric patients (age <18 years) were lower than those observed in adults, suggesting everolimus clearance (adjusted to body surface area) was higher in pediatric patients compared to adults.
Race/ethnicity: Average everolimus exposure may be higher in Japanese individuals (based on an Afinitor cross-study comparison). Oral everolimus clearance is 20% higher (on average) in Black patients compared with White patients.
