AFINITOR DISPERZ® (everolimus tablets for oral suspension) is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives, or to any of the excipients.
AFINITOR DISPERZ is indicated for the adjunctive treatment of adult and pediatric patients aged 2 years and older with TSC-associated partial-onset seizures.
IMPORTANT SAFETY INFORMATION
AFINITOR DISPERZ is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives, or to any of the excipients.
Noninfectious Pneumonitis: Noninfectious pneumonitis is a class effect of rapamycin derivatives. Noninfectious pneumonitis was reported in up to 19% of patients treated with AFINITOR/AFINITOR DISPERZ in clinical trials, some cases reported with pulmonary hypertension (including pulmonary arterial hypertension) as a secondary event. The incidence of grade 3 and 4 noninfectious pneumonitis was up to 4.0% and up to 0.2%, respectively. Fatal outcomes have been observed. Consider a diagnosis of noninfectious pneumonitis in patients presenting with nonspecific 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 AFINITOR DISPERZ without dose alteration in patients who develop radiological changes suggestive of noninfectious pneumonitis and have few or no symptoms. Imaging appears to overestimate the incidence of clinical pneumonitis. For grade 2 to 4 noninfectious pneumonitis, withhold or permanently discontinue AFINITOR DISPERZ based on severity. 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.
Infections: AFINITOR DISPERZ has immunosuppressive properties and may predispose patients to bacterial, fungal, viral, or protozoal infections, including those with opportunistic pathogens. Localized and systemic infections, including pneumonia, mycobacterial infections, other bacterial infections; invasive fungal infections, such as aspergillosis, candidiasis, or PJP; and viral infections, including reactivation of hepatitis B virus, have occurred. Some of these infections have been severe (eg, sepsis, sepsis shock, or resulting in multisystem organ failure) or fatal. The incidence of grade 3 and 4 infections was up to 10% and up to 3%, respectively. The incidence of serious infections was reported at a higher frequency in patients <6 years of age. Complete treatment of preexisting invasive fungal infections prior to starting treatment. Monitor for signs and symptoms of infection. Withhold or permanently discontinue AFINITOR DISPERZ based on severity of infection. Administer prophylaxis for PJP when concomitant use of corticosteroids or other immunosuppressive agents are required.
Severe Hypersensitivity Reactions: Hypersensitivity reactions to AFINITOR DISPERZ have been observed and include anaphylaxis, dyspnea, flushing, chest pain, and angioedema (eg, swelling of the airways or tongue, with or without respiratory impairment). The incidence of grade 3 hypersensitivity reactions was up to 1%. Permanently discontinue AFINITOR DISPERZ for the development of clinically significant hypersensitivity.
Angioedema With Concomitant Use of Angiotensin-Converting Enzyme (ACE) Inhibitors: Patients taking concomitant ACE inhibitor with AFINITOR DISPERZ may be at increased risk for angioedema (eg, swelling of the airways or tongue, with or without respiratory impairment). In a pooled analysis, the incidence of angioedema in patients taking everolimus with an ACE inhibitor was 6.8% compared to 1.3% in the control arm with an ACE inhibitor. Permanently discontinue AFINITOR DISPERZ for angioedema.
Stomatitis: Stomatitis, including mouth ulcers and oral mucositis, has occurred in patients treated with AFINITOR/AFINITOR DISPERZ at an incidence ranging from 44% to 78% across the clinical trial experience. Grade 3/4 stomatitis was reported in 4% to 9% of patients. Stomatitis most often occurs within the first 8 weeks of treatment. When starting AFINITOR DISPERZ, initiating dexamethasone alcohol-free oral solution as a swish and spit mouthwash reduces the incidence and severity of stomatitis. If stomatitis does occur, mouthwashes and/or other topical treatments are recommended, but alcohol-, hydrogen peroxide-, iodine-, or thyme-containing products should be avoided. Antifungal agents should not be used unless fungal infection has been diagnosed.
Renal Failure: Cases of renal failure (including acute renal failure), some with a fatal outcome, have occurred in patients taking AFINITOR. Elevations of serum creatinine and proteinuria have been reported in patients taking AFINITOR/AFINITOR DISPERZ. The incidence of grade 3 and 4 elevations of serum creatinine was up to 2% and up to 1%, respectively. The incidence of grade 3 and 4 proteinuria was up to 1% and up to 0.5%, respectively. Monitor renal function prior to starting AFINITOR DISPERZ and annually thereafter. Monitor renal function at least every 6 months in patients who have additional risk factors for renal failure.
Impaired Wound Healing: AFINITOR DISPERZ delays wound healing and increases the occurrence of wound-related complications like wound dehiscence, wound infection, incisional hernia, lymphocele, and seroma. These wound-related complications may require surgical intervention. Exercise caution with the use of AFINITOR DISPERZ in the perisurgical period.
Metabolic Disorders: Hyperglycemia, hypercholesterolemia, and hypertriglyceridemia have been reported in patients taking AFINITOR/AFINITOR DISPERZ at an incidence up to 75%, 86%, and 73%, respectively. The incidence of these grade 3 and 4 laboratory abnormalities was up to 15% and up to 0.4%, respectively. In nondiabetic patients, monitor fasting serum glucose prior to starting AFINITOR DISPERZ and annually thereafter. In diabetic patients, monitor fasting serum glucose more frequently as clinically indicated. Monitor lipid profile prior to starting AFINITOR DISPERZ and once yearly thereafter. When possible, achieve optimal glucose and lipid control prior to starting AFINITOR DISPERZ. For grade 3 to 4 metabolic events, withhold or permanently discontinue AFINITOR DISPERZ based on severity.
Myelosuppression: Anemia, lymphopenia, neutropenia, and thrombocytopenia have been reported in patients taking AFINITOR/AFINITOR DISPERZ. The incidence of these grade 3 and 4 laboratory abnormalities was up to 16% and up to 2%, respectively. Monitor complete blood count prior to starting AFINITOR DISPERZ, every 6 months for the first year of treatment, and annually thereafter. Withhold or permanently discontinue AFINITOR DISPERZ based on severity.
Risk of Infection or Reduced Immune Response With Vaccinations: The safety of immunization with live vaccines during AFINITOR DISPERZ therapy has not been studied. Due to the potential increased risk of infection and/or reduced immune response to the vaccine, avoid the use of live vaccines and close contact with individuals who have received live vaccines during treatment with AFINITOR DISPERZ. Due to the potential increased risk of infection or reduced immune response with vaccination, complete the recommended childhood series of live vaccinations according to American Council on Immunization Practices (ACIP) guidelines prior to the start of therapy. An accelerated vaccination schedule may be appropriate.
Embryo-Fetal Toxicity: Based on animal studies and the mechanism of action, AFINITOR DISPERZ can cause fetal harm when administered to a pregnant woman. 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 clinical dose of 10 mg once daily. Advise pregnant women of the potential risk to a fetus. Advise female patients of reproductive potential to avoid becoming pregnant and to use effective contraception during treatment with AFINITOR DISPERZ and for 8 weeks after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with AFINITOR DISPERZ and for 4 weeks after the last dose.
Adverse Reactions: In patients with TSC-associated partial-onset seizures, the most common adverse reaction reported for AFINITOR DISPERZ (incidence ≥30%, all grades) was stomatitis (55% low trough, 64% high trough). The most common grade 3/4 adverse reactions (incidence ≥2%) were stomatitis, pneumonia, and irregular menstruation. Updated safety information from 357 patients treated with AFINITOR DISPERZ for a median duration of 48 weeks identified the following additional notable adverse reactions: hypersensitivity (0.6%), angioedema (0.3%), and ovarian cyst (0.3%).
Laboratory Abnormalities: In patients with TSC-associated partial-onset seizures, the most common laboratory abnormality (incidence ≥50%, all grades) was hypercholesterolemia (86% low trough, 85% high trough). The most common grade 3/4 laboratory abnormality (incidence ≥2%) was neutropenia.
