EVEROLIMUS

1 INDICATIONS AND USAGE Everolimus tablets for oral suspension are kinase inhibitor indicated for the treatment of adult and pediatric patients aged 1 year and older with TSC who have subependymal giant cell astrocytoma (SEGA) that requires therapeutic intervention but cannot be curatively resected. ( 1.5 ) 1.5 Tuberous Sclerosis Complex (TSC)-Associated Subependymal Giant Cell Astrocytoma (SEGA) Everolimus tablets for oral suspension are indicated in adult and pediatric patients aged 1 year and older with TSC for the treatment of SEGA that requires therapeutic intervention but cannot be curatively resected.

2 DOSAGE AND ADMINISTRATION Do not combine AFINITOR and everolimus tablets for oral suspension to achieve the total daily dose. ( 2.1 ) Modify the dose for patients with hepatic impairment or for patients taking drugs that inhibit or induce P-glycoprotein (P-gp) and CYP3A4. ( 2.1 ) TSC-Associated SEGA: 4.5 mg/m 2 orally once daily; adjust dose to attain trough concentrations of 5 ng/mL to 15 ng/mL. ( 2.6 , 2.8 ) 2.1 Important Dosage Information Do not combine AFINITOR and everolimus tablets for oral suspension to achieve the total dose. Modify the dosage for patients with hepatic impairment or for patients taking drugs that inhibit or induce P-glycoprotein (P-gp) and CYP3A4 [see Dosage and Administration (2.10 , 2.11 , 2.12) ] . 2.6 Recommended Dosage for Tuberous Sclerosis Complex (TSC)-Associated Subependymal Giant Cell Astrocytoma (SEGA) The recommended starting dosage of everolimus tablets for oral suspension is 4.5 mg/m 2 orally once daily until disease progression or unacceptable toxicity [see Dosage and Administration (2.8) ] . 2.8 Therapeutic Drug Monitoring (TDM) and Dose Titration for Tuberous Sclerosis Complex (TSC)-Associated Subependymal Giant Cell Astrocytoma (SEGA) Monitor everolimus whole blood trough concentrations at time points recommended in Table 1. Titrate the dose to attain trough concentrations of 5 ng/mL to 15 ng/mL. Adjust the dose using the following equation: New dose * = current dose x (target concentration divided by current concentration) * The maximum dose increment at any titration must not exceed 5 mg. Multiple dose titrations may be required to attain the target trough concentration. When possible, use the same assay and laboratory for TDM throughout treatment.

5 WARNINGS AND PRECAUTIONS Non-Infectious Pneumonitis: Monitor for clinical symptoms or radiological changes. Withhold or permanently discontinue based on severity. ( 2.9 , 5.1 ) Infections: Monitor for signs and symptoms of infection. Withhold or permanently discontinue based on severity. ( 2.9 , 5.2 ) Severe Hypersensitivity Reactions: Permanently discontinue for clinically significant hypersensitivity. ( 5.3 ) Angioedema: Patients taking concomitant angiotensin-converting-enzyme (ACE) inhibitors may be at increased risk for angioedema. Permanently discontinue for angioedema. ( 5.4 , 7.2 ) Stomatitis: Initiate dexamethasone alcohol-free mouthwash when starting treatment. ( 5.5 ) Renal Failure: Monitor renal function prior to treatment and periodically thereafter. ( 5.6 ) Risk of Impaired Wound Healing: Withhold for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of treatment after resolution of wound healing complications has not been established. ( 5.7 ) Metabolic Disorders: Monitor serum glucose and lipids prior to treatment and periodically thereafter. Withhold or permanently discontinue based on severity. ( 2.9 , 5.9 ) Myelosuppression: Monitor hematologic parameters prior to treatment and periodically thereafter. Withhold or permanently discontinue based on severity. ( 2.9 , 5.10 ) Risk of Infection or Reduced Immune Response with Vaccination: Avoid live vaccines and close contact with those who have received live vaccines. Complete recommended childhood vaccinations prior to starting treatment. ( 5.11 ) Radiation Sensitization and Radiation Recall: Severe radiation reactions may occur. ( 5.12 , 6.2 ) Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.13 , 8.1 , 8.3 ) 5.1 Non-infectious Pneumonitis Non-infectious pneumonitis is a class effect of rapamycin derivatives. Non-infectious pneumonitis was reported in up to 19% of patients treated with everolimus tablets for oral suspension in clinical trials, some cases were reported with pulmonary hypertension (including pulmonary arterial hypertension) as a secondary event. The incidence of Grade 3 and 4 non-infectious pneumonitis was up to 4% and up to 0.2%, respectively [see Adverse Reactions (6.1) ] . Fatal outcomes have been observed. Consider a diagnosis of non-infectious pneumonitis in patients presenting with non-specific respiratory signs and symptoms. Consider opportunistic infections, such as pneumocystis jiroveci pneumonia (PJP) in the differential diagnosis. Advise patients to report promptly any new or worsening respiratory symptoms. Continue everolimus tablets for oral suspension without dose alteration in patients who develop radiological changes suggestive of non-infectious pneumonitis and have few or no symptoms. Imaging appears to overestimate the incidence of clinical pneumonitis. For Grade 2 to 4 non-infectious pneumonitis, withhold or permanently discontinue everolimus tablets for oral suspension based on severity [see Dosage and Administration (2.9) ] . Corticosteroids may be indicated until clinical symptoms resolve. Administer prophylaxis for PJP when concomitant use of corticosteroids or other immunosuppressive agents are required. The development of pneumonitis has been reported even at a reduced dose. 5.2 Infections Everolimus tablets for oral suspension have immunosuppressive properties and may predispose patients to bacterial, fungal, viral, or protozoal infections, including infections with opportunistic pathogens [see Adverse Reactions (6.1) ] . Localized and systemic infections, including pneumonia, mycobacterial infections, other bacterial infections, invasive fungal infections (e.g., aspergillosis, candidiasis, or PJP) and viral infections (e.g., reactivation of hepatitis B virus) have occurred. Some of these infections…

Inducers Increase the dose for patients taking everolimus tablets for oral suspension with a P-gp and strong CYP3A4 inducer as recommended [see Dosage and Administration (2.12) , Clinical Pharmacology (12.3) ] . 7.2 Effects of Combination Use of Angiotensin Converting Enzyme (ACE) Inhibitors Patients taking concomitant ACE inhibitors with everolimus tablets for oral suspension may be at increased risk for angioedema. Avoid the concomitant use of ACE inhibitors with everolimus tablets for oral suspension [see Warnings and Precautions (5.4) ] .

8.1 Pregnancy Risk Summary Based on animal studies and the mechanism of action [see Clinical Pharmacology (12.1) ] , everolimus tablets for oral suspension can cause fetal harm when administered to a pregnant woman. There are limited case reports of AFINITOR use in pregnant women; however, these reports are not sufficient to inform about risks of birth defects or miscarriage. In animal studies, everolimus caused embryo-fetal toxicities in rats when administered during the period of organogenesis at maternal exposures that were lower than human exposures at the recommended dose of AFINITOR 10 mg orally once daily (see Data) . Advise pregnant women of the potential risk to the fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage is 2% to 4% and 15% to 20% of clinically recognized pregnancies, respectively. Data Animal Data In animal reproductive studies, oral administration of everolimus to female rats before mating and through organogenesis induced embryo-fetal toxicities, including increased resorption, pre-implantation and post-implantation loss, decreased numbers of live fetuses, malformation (e.g., sternal cleft) and retarded skeletal development. These effects occurred in the absence of maternal toxicities. Embryo-fetal toxicities in rats occurred at doses ≥ 0.1 mg/kg (0.6 mg/m 2 ) with resulting exposures of approximately 4% of the human exposure at the recommended dose of AFINITOR 10 mg orally once daily based on area under the curve (AUC). In rabbits, embryo-toxicity evident as an increase in resorptions occurred at an oral dose of 0.8 mg/kg (9.6 mg/m 2 ), approximately 1.6 times the recommended dose of AFINITOR 10 mg orally once daily or the median dose administered to patients with tuberous sclerosis complex (TSC)-associated subependymal giant cell astrocytoma (SEGA). The effect in rabbits occurred in the presence of maternal toxicities. In a pre- and post-natal development study in rats, animals were dosed from implantation through lactation. At the dose of 0.1 mg/kg (0.6 mg/m 2 ), there were no adverse effects on delivery and lactation or signs of maternal toxicity; however, there were reductions in body weight (up to 9% reduction from the control) and in survival of offspring (~5% died or missing). There were no drug-related effects on the developmental parameters (morphological development, motor activity, learning, or fertility assessment) in the offspring.

8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to starting everolimus tablets for oral suspension [see Use in Specific Populations (8.1) ] . Contraception Everolimus tablets for oral suspension can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1) ] . Females: Advise female patients of reproductive potential to use effective contraception during treatment with everolimus tablets for oral suspension and for 8 weeks after the last dose. Males: Advise male patients with female partners of reproductive potential to use effective contraception during treatment with everolimus tablets for oral suspension and for 4 weeks after the last dose. Infertility Females: Menstrual irregularities, secondary amenorrhea and increases in luteinizing hormone (LH) and follicle stimulating hormone (FSH) occurred in female patients taking everolimus tablets for oral suspension. Based on these findings, everolimus tablets for oral suspension may impair fertility in female patients [see Adverse Reactions (6.1) , Nonclinical Toxicology (13.1) ] . Males: Cases of reversible azoospermia have been reported in male patients taking AFINITOR. In male rats, sperm motility, sperm count, plasma testosterone levels and fertility were diminished at AUC similar to those of the clinical dose of AFINITOR 10 mg orally once daily. Based on these findings, everolimus tablets for oral suspension may impair fertility in male patients [see Nonclinical Toxicology (13.1) ] .

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Non-Infectious Pneumonitis [see Warnings and Precautions (5.1) ] Infections [see Warnings and Precautions (5.2) ] Severe Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Angioedema with Concomitant Use of ACE inhibitors [see Warnings and Precautions (5.4) ] Stomatitis [see Warnings and Precautions (5.5) ] Renal Failure [see Warnings and Precautions (5.6) ] Impaired Wound Healing [see Warnings and Precautions (5.7) ] Metabolic Disorders [see Warnings and Precautions (5.9) ] Myelosuppression [see Warnings and Precautions (5.10) ] Radiation Sensitization and Radiation Recall [see Warnings and Precautions (5.12) ] TSC-Associated SEGA: Most common adverse reactions (incidence ≥ 30%) are stomatitis and respiratory tract infection.

TSC-Associated Subependymal Giant Cell Astrocytoma (SEGA) The data described below are based on a randomized (2:1), double-blind, placebo-controlled trial (EXIST-1) of AFINITOR in 117 patients with SEGA and TSC. The median age of patients was 9.5 years (0.8 to 26 years), 93% were white and 57% were male. The median duration of blinded study treatment was 52 weeks (24 to 89 weeks) for patients receiving AFINITOR. The most common adverse reactions reported for AFINITOR (incidence ≥ 30%) were stomatitis and respiratory tract infection. The most common Grade 3 to 4 adverse reactions (incidence ≥ 2%) were stomatitis, pyrexia, pneumonia, gastroenteritis, aggression, agitation and amenorrhea. The most common laboratory abnormalities (incidence ≥ 50%) were hypercholesterolemia and elevated partial thromboplastin time. The most common Grade 3 to 4 laboratory abnormality (incidence ≥ 3%) was neutropenia. There were no adverse reactions resulting in permanent discontinuation. Dose adjustments (interruptions or reductions) due to adverse reactions occurred in 55% of AFINITOR-treated patients. The most common adverse reaction leading to AFINITOR dose adjustment was stomatitis. Adverse reactions reported with an incidence of ≥ 10% for patients receiving AFINITOR and occurring more frequently with AFINITOR than with placebo are reported in Table 16. Laboratory abnormalities are presented in Table 17.
