Important Safety Information

AFINITOR is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives, or to any of the excipients.

Non-infectious Pneumonitis: Non-infectious pneumonitis was reported in 11-14% of patients treated with Afinitor. The incidence of Common Terminology Criteria (CTC) grade 3 and 4 non-infectious pneumonitis was 1.6%-4.0% and 0.1%, respectively. Fatal outcomes have been observed. If symptoms are moderate, patients should be managed with dose interruption until symptoms improve. If symptoms are severe, AFINITOR therapy should be discontinued. Under both circumstances, corticosteroids may be indicated and AFINITOR may be reintroduced at 5 mg daily, or approximately 50% lower than the dose previously administered, depending on the individual clinical circumstances. The development of pneumonitis has been reported even at a reduced dose.

Infections: AFINITOR has immunosuppressive properties and may predispose patients to localized or systemic bacterial, fungal, viral, or protozoal infections (including those with opportunistic pathogens). Viral infections may include reactivation of hepatitis B infection. Some of these infections have been severe (e.g., leading to respiratory or hepatic failure) or fatal. Physicians and patients should be aware of the increased risk of infection with Afinitor. Treatment of pre-existing invasive fungal infections should be completed prior to starting treatment. Be vigilant for signs and symptoms of infection and institute appropriate treatment promptly; interruption or discontinuation of AFINITOR should be considered. Discontinue AFINITOR if invasive systemic fungal infection is diagnosed and institute appropriate treatment.

Oral Ulceration: Oral ulcerations (i.e., mouth ulcers, stomatitis, and oral mucositis) are the most frequently occurring adverse event and occur in approximately 70% of advanced PNET patients, 44% of advanced RCC patients, and 86% of SEGA patients, which were mostly Grade 1 or 2. Grade 3 or 4 stomatitis was reported in 6% of patients with neuroendocrine tumors. In such cases, topical treatments are recommended, but alcohol- or peroxide-containing mouthwashes 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 been observed in patients treated with AFINITOR.

Laboratory Tests and Monitoring: Elevations of serum creatinine, proteinuria, glucose, lipids, and triglycerides, and reductions of hemoglobin, lymphocytes, neutrophils, and platelets have been reported. Renal function, blood glucose, lipids, and hematologic parameters should be evaluated prior to treatment and periodically thereafter. When possible, optimal glucose and lipid control should be achieved before starting a patient on AFINITOR.

Drug-drug Interactions: Avoid co-administration with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, indinavir, nelfinavir, voriconazole). Use caution and reduce the AFINITOR dose to 2.5 mg daily if co-administration with a moderate CYP3A4 and/or PgP inhibitor is required (e.g., amprenavir, fosamprenavir, aprepitant, erythromycin, fluconazole, verapamil, diltiazem). Avoid co-administration with strong CYP3A4 inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital); however, if co-administration is required in advanced PNET or RCC patients, increase the AFINITOR dose from 10 mg daily up to 20 mg daily, using 5 mg increments. In SEGA patients, double the AFINITOR dose.

Hepatic Impairment: AFINITOR should not be used in patients with severe hepatic impairment. Exposure of everolimus was increased in patients with moderate hepatic impairment. In advanced PNET and RCC patients, the AFINITOR dose should be reduced to 5 mg daily for patients with moderate hepatic impairment. In SEGA patients, adjustment to the starting dose may not be needed; however, subsequent dosing should be individualized based on therapeutic drug monitoring.

Vaccinations: The use of live vaccines and close contact with those who have received live vaccines should be avoided during treatment with AFINITOR. The timing of routine vaccinations in pediatric patients with SEGA should be considered prior to the start of AFINITOR therapy.

Use in Pregnancy: Fetal harm can occur if AFINITOR is administered to a pregnant woman. Women of childbearing potential should be advised to use an effective method of contraception while using AFINITOR and for up to 8 weeks after ending treatment.
