ALERT: U.S. Boxed Warning

Immunosuppression (Zortress):

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 use everolimus. Manage patients receiving the drug 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.

Graft thrombosis (Zortress):

An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days post-transplantation.

Nephrotoxicity (Zortress):

Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with everolimus. Therefore, use reduced doses of cyclosporine in combination with everolimus in order to reduce renal dysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations.

Mortality in heart transplant (Zortress):

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.

Dosage adjustment for concomitant CYP3A4 inhibitors/inducers and/or P-gp inhibitors:

Breast cancer, neuroendocrine tumors, RCC, renal angiomyolipoma:

CYP3A4/P-gp inducers: Strong inducers: Avoid coadministration with strong CYP3A4/P-gp inducers (eg, carbamazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, St Johns wort); if concomitant use cannot be avoided, consider doubling the everolimus dose, using increments of 5 mg or less, with careful monitoring. If the strong CYP3A4/P-gp enzyme inducer is discontinued, consider allowing 3 to 5 days to elapse prior to reducing the everolimus to the dose used prior to initiation of the CYP3A4/P-gp inducer.

CYP3A4/P-gp inhibitors:

Strong inhibitors: Avoid concomitant administration with strong CYP3A4/P-gp inhibitors (eg, atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole).

Moderate CYP3A4/P-gp inhibitors (eg, amprenavir, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, verapamil): Reduce everolimus dose to 2.5 mg once daily; may consider increasing from 2.5 mg to 5 mg once daily based on patient tolerance. When the moderate inhibitor is discontinued, allow ~2 to 3 days to elapse prior to adjusting the everolimus upward to the recommended starting dose or to the dose used prior to initiation of the moderate inhibitor.

Renal transplantation: Dosage adjustments may be necessary based on everolimus serum concentrations

SEGA:

CYP3A4/P-gp inducers: Strong inducers: Avoid concomitant administration with strong CYP3A4/P-gp inducers (eg, carbamazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, St John's wort); if concomitant use cannot be avoided, an initial starting everolimus dose of 9 mg/m2 once daily is recommended, or, double the everolimus dose and assess tolerability; assess trough concentration after ~2 weeks; adjust dose as necessary based on therapeutic drug monitoring to maintain target trough concentrations of 5 to 15 ng/mL. If the strong CYP3A4 enzyme inducer is discontinued, reduce the everolimus dose by ~50% or to the dose used prior to initiation of the CYP3A4/P-gp inducer; reassess trough concentration after ~2 weeks.

CYP3A4/P-gp inhibitors:

Strong inhibitors: Avoid concomitant administration with strong CYP3A4/P-gp inhibitors (eg, atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole).

Moderate CYP3A4/P-gp inhibitors (eg, amprenavir, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, verapamil):

Currently taking a moderate CYP3A4/P-gp inhibitor and starting everolimus: 2.5 mg/m2 once daily.

Currently taking everolimus and starting a moderate CYP3A4/P-gp inhibitor: Reduce everolimus dose by ~50%; if dose reduction is required for patients receiving the lowest strength available, administer every other day.

Discontinuing a moderate CYP3A4/P-gp inhibitor after concomitant use with everolimus: Discontinue moderate inhibitor and allow 2 to 3 days to elapse prior to resuming the everolimus dose used prior to initiation of the moderate inhibitor.

Therapeutic drug monitoring: Assess trough concentration ~2 weeks after everolimus initiation or dosage modifications, or initiation or changes to concurrent CYP3A4/P-gp inhibitor therapy; adjust maintenance dose if needed at 2-week intervals to achieve and maintain trough concentrations between 5 and 15 ng/mL.

Warnings/Precautions


Special Populations: Hepatic Function Impairment

The average AUC in subjects with mild impairment was 1.6-fold higher than that of patients with normal hepatic function (following a 10 mg dose); in moderate 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 impairment the AUC was 3.6-fold higher than that of patients with normal hepatic function (following a 10 mg dose).


Special Populations: Elderly

A limited reduction in oral clearance of 0.33% per year was estimated in renal transplant patients.


Special Populations: Race

The average exposure is higher in Japanese patients compared with non-Japanese patients. Oral clearance is 20% higher in black patients compared with white patients. The importance of these differences in safety and efficacy has not been established.


Warnings/Precautions

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. Monitor blood counts at baseline and periodically.

- Edema: Generalized edema (including peripheral edema and lymphedema) and local fluid accumulation (eg, pericardial effusion, pleural effusion, ascites) may occur.

- Fertility effects: 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.

- Graft thrombosis: [U.S. Boxed Warning]: An increased risk of renal arterial and venous thrombosis has been reported with use in renal transplantation, generally within the first 30 days after transplant; may result in graft loss.

- Hepatic artery thrombosis: 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.

- Infections: [US Boxed Warning]: Everolimus has immunosuppressant properties which may result in infection; the risk of developing bacterial (including mycobacterial), viral, fungal, and protozoal infections and for local, opportunistic (including polyomavirus infection), and/or systemic infections is increased; may lead to sepsis, respiratory failure, hepatic failure, or fatality. Polyoma virus infection in transplant patients may be serious and/or fatal. Polyoma virus-associated nephropathy (due to BK virus), which may result in serious cases of deteriorating renal function and renal graft loss, has been observed with use in renal transplantation. JC virus-associated progressive multiple leukoencephalopathy (PML) may also be associated with everolimus use in transplantation. Reduced immunosuppression (taking into account the risks of rejection) should be considered with evidence of polyoma virus infection or PML. Reactivation of hepatitis B has been observed in patients receiving everolimus. Resolve preexisting invasive fungal infections prior to treatment initiation. Cases (some fatal) of Pneumocystis jiroveci pneumonia (PCP) have been reported with everolimus use. Consider PCP prophylaxis in patients receiving concomitant corticosteroid or other immunosuppressant therapy. In addition, transplant recipient patients should receive prophylactic therapy for PCP and for cytomegalovirus (CMV). Monitor for signs and symptoms of infection during treatment. Discontinue if invasive systemic fungal infection is diagnosed (and manage with appropriate antifungal therapy).

- Malignancy: [US Boxed Warning]: 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. Higher serum everolimus concentrations are associated with an increased risk for hyperlipidemia. Use has not been studied in patients with baseline cholesterol >350 mg/dL. Monitor fasting glucose and lipid profile prior to treatment initiation and periodically thereafter. Monitor more frequently in patients with concomitant medications affecting glucose. 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. Manage with appropriate medical therapy (if possible, optimize glucose control and lipids prior to treatment initiation). Antihyperlipidemic therapy may not normalize levels.

- Mucositis/stomatitis: Use is associated with mouth ulcers, mucositis, and stomatitis; manage with topical therapy; avoid the use of alcohol-, hydrogen peroxide " “, iodine-, or thyme-based mouthwashes. 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), renal failure, and proteinuria have been observed with everolimus use; monitor renal function (BUN, creatinine, and/or urinary protein). Risk of nephrotoxicity may be increased when administered with calcineurin inhibitors (eg, cyclosporine, tacrolimus); dosage adjustment of calcineurin inhibitor is necessary. Monitor for proteinuria; 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. Symptoms include dyspnea, cough, hypoxia and/or pleural effusion; 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 Pneumocystis jiroveci pneumonia (PCP) when evaluating clinical symptoms. May require treatment interruption followed by dose reduction (pneumonitis has developed even with reduced doses) and/or corticosteroid therapy; discontinue for grade 4 pneumonitis. Consider discontinuation for recurrence of grade 3 toxicity after dosage reduction. In patients who require steroid therapy for symptom management, consider PCP prophylaxis. Imaging may overestimate the incidence of clinical pneumonitis.

- Wound healing complication: Everolimus use may delay wound healing and increase the occurrence of wound-related complications (eg, wound dehiscence, infection, incisional hernia, lymphocele, seroma); may require surgical intervention. Use everolimus with caution in the peri-surgical period.

Disease-related concerns:

- Heart transplantation: [US Boxed Warning]: 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 on in the postoperative period (Andreassen 2014; Andreassen 2016; Costanza, 2010; Hirt 2013; Hollis 2015).

- Hepatic impairment: Everolimus exposure is increased in patients with hepatic impairment. For patients with breast cancer, neuroendocrine tumors, RCC, or renal angiomyolipoma with mild and moderate hepatic impairment, reduced doses are recommended; in patients with severe hepatic impairment, use is recommended (at reduced doses) if the potential benefit outweighs risks. Reduced doses are recommended in transplant patients with hepatic impairment (Child-Pugh class A, B, or C); monitor whole blood trough levels closely. For patients with SEGA, reduced doses may be needed (based on therapeutic drug monitoring) for mild and moderate hepatic impairment, and are recommended in severe hepatic impairment; monitor whole blood trough levels.

- Hereditary galactose intolerance: Avoid use in patients with galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption; may result in diarrhea and malabsorption.

- Renal impairment: An increased incidence of rash, infection and dose interruptions have been reported in patients with renal insufficiency (CrCl ≤60 mL/minute) who received mTOR inhibitors for the treatment of renal cell cancer (Gupta 2011). Serum creatinine elevations and proteinuria have been reported. Monitor renal function (BUN, serum creatinine, urinary protein) at baseline and periodically, especially if risk factors for further impairment exist. Pharmacokinetic studies have not been conducted; dosage adjustments are not required based on renal impairment.

- Transplantation (solid organ): The safety and efficacy of everolimus in renal transplantation patients with high-immunologic risk or in solid organ transplant other than renal or liver have not been established. In liver transplant, tacrolimus has minimal or no pharmacokinetic impact on everolimus concentrations.

Concurrent drug therapy issues:

- Calcineurin inhibitor combination therapy: [US Boxed Warning]: Due to the increased risk for nephrotoxicity in renal transplantation, avoid standard doses of cyclosporine in combination with everolimus; reduced cyclosporine doses are recommended when everolimus is used in combination with cyclosporine. Therapeutic monitoring of cyclosporine and everolimus concentrations is recommended. Everolimus and cyclosporine combination therapy may result in increased proteinuria and may increase the risk for thrombotic microangiopathy/thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TMA/TTP/HUS); monitor blood counts. In liver transplantation, the tacrolimus dose and target range should be reduced to minimize the risk of nephrotoxicity. Eliminating calcineurin inhibitors from the immunosuppressive regimen may result in acute rejection.

- Drug-drug/drug-food interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

- HMG-CoA reductase inhibitors: In transplant patients, avoid the use of certain HMG-CoA reductase inhibitors (eg, simvastatin, lovastatin); may increase the risk for rhabdomyolysis due to the potential interaction with cyclosporine (which may be given in combination with everolimus for transplantation).

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 SEGA. Do not combine formulations to achieve total desired dose.

Special handling:

- Hazardous agent: Use appropriate precautions for handling and disposal (NIOSH 2014 [group 1]). To avoid potential contact with everolimus, caregivers should wear gloves when preparing suspension from tablets for oral suspension.

Other warnings/precautions:

- Appropriate use: Continue treatment with everolimus for renal cell cancer as long as clinical benefit is demonstrated or until occurrence of unacceptable toxicity.

- 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.

- Experienced physician: [US Boxed Warning]: In transplantation, everolimus should only be used by physicians experienced in immunosuppressive therapy and management of transplant patients. Adequate laboratory and supportive medical resources must be readily available.

- 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 treated for SEGA, complete recommended series of live virus childhood vaccinations prior to treatment (if immediate everolimus treatment is not indicated); an accelerated vaccination schedule may be appropriate.


Pregnancy Risk Factor

C (Zortress)


Pregnancy Considerations

Adverse events were observed in animal reproduction studies with exposures lower than expected with human doses. Based on the mechanism of action, may cause fetal harm if administered during pregnancy. Women of reproductive potential should be advised to avoid pregnancy and use highly effective birth control during treatment and for up to 8 weeks after everolimus discontinuation.

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. Females of reproductive potential should consider family planning options prior to therapy.

The National Transplantation Pregnancy Registry (NTPR) (Temple University) is a registry for pregnant women taking immunosuppressants following any solid organ transplant. The NTPR encourages reporting of all immunosuppressant exposures during pregnancy in transplant recipients at 877-955-6877.


Actions


Pharmacology

Everolimus is a macrolide immunosuppressant and a mechanistic target of rapamycin (mTOR) inhibitor which has antiproliferative and antiangiogenic properties, and also 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, 2012).


Absorption

Rapid, but moderate


Distribution

Apparent Vd: 128 to 589 L; volume of distribution in children (3 to 16 years) lower than adults (Van Damme-Lombaerts 2002)


Metabolism

Extensively metabolized in the liver via CYP3A4; forms 6 weak metabolites


Excretion

Feces (80%, based on solid organ transplant studies); Urine (~5%, based on solid organ transplant studies); clearance in pediatric patients lower than adults possibly due to distributive differences (Van Damme-Lombaerts 2002)


Time to Peak

1 to 2 hours


Half-Life Elimination

~30 hours; in children (3 to 16 years), half-life similar to adult data (Van Damme-Lombaerts 2002)


Protein Binding

~74%
