Hypersensitivity to AURLUMYN or any of its components.
Hypersensitivity to everolimus, sirolimus, or any component of the formulation
Avoid alcohol. No specific food interactions, but maintain a balanced diet. Take with food or milk if gastrointestinal upset occurs.
Avoid grapefruit, grapefruit juice, and Seville oranges (including marmalade) due to CYP3A4 inhibition increasing everolimus levels. Take consistently with or without food, but high-fat meals reduce absorption. Avoid St. John's wort.
First trimester: Increased risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and limited human data. Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and preterm birth. Avoid in pregnancy unless benefit outweighs risk.
Pregnancy Category D. Positive evidence of human fetal risk. Based on its mechanism of action (m TOR inhibitor) and animal studies, AFINITOR (everolimus) is embryotoxic and fetotoxic. First trimester exposure carries risk of structural anomalies; second and third trimester exposure may cause fetal growth restriction, oligohydramnios, and renal impairment. Use only if benefit outweighs risk.
No data on excretion in human milk; M/P ratio unknown. Due to potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment and for at least 2 weeks after last dose.
No data on presence in human milk, effects on breastfed infant, or milk production. M/P ratio unknown. Breastfeeding is not recommended due to potential adverse effects on the developing immune system and growth.
No specific dosing adjustments established for pregnancy. Pregnancy-induced pharmacokinetic changes (increased volume of distribution, enhanced renal clearance) may reduce drug exposure; consider therapeutic drug monitoring if available.
No specific dose adjustments established for pregnancy. Pharmacokinetic changes in pregnancy (increased volume of distribution, altered hepatic metabolism) may reduce drug exposure; however, given the teratogenic risk, use during pregnancy should be avoided. If unavoidable, consider therapeutic drug monitoring if available and adjust dose to achieve target trough concentrations (typically 3-8 ng/m L for transplant indications; for oncology, refer to specific protocol).
AURLUMYN is a proprietary name for auranofin, an oral gold compound used for rheumatoid arthritis. Monitor for oral ulcerations, dermatitis, and proteinuria. Renal function and CBC should be checked monthly. Avoid concurrent use with penicillamine, antimalarials, immunosuppressants, or cytotoxic drugs. Onset of action may be delayed 3-6 months.
Monitor renal function and blood glucose regularly; Afinitor (everolimus) can cause non-infectious pneumonitis, so obtain baseline chest imaging and assess for new or worsening respiratory symptoms. Adjust dose for moderate hepatic impairment (Child-Pugh B). Avoid live vaccines during treatment.

Common clinical questions about AURLUMYN vs AFINITOR, answered by our medical review team.
AURLUMYN is a Antineoplastic Agent that works by Microtubule inhibitor that binds to tubulin and disrupts microtubule dynamics, leading to mitotic arrest and apoptosis.. AFINITOR is a mTOR Inhibitor Antineoplastic that works by Inhibitor of mammalian target of rapamycin (m TOR), specifically the m TORC1 complex, by binding to the FKBP-12 protein, reducing cell proliferation, angiogenesis, and glucose uptake.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between AURLUMYN and AFINITOR depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of AURLUMYN is: Intravenous, 6 mg/kg every 4 weeks for 6 cycles; each cycle: Days 1 and 15 of a 28-day cycle.. The standard adult dose of AFINITOR is: 10 mg orally once daily for advanced breast cancer, neuroendocrine tumors, and renal cell carcinoma; 10 mg orally once daily for subependymal giant cell astrocytoma (SEGA) in adults; 5 mg/m^2 orally once daily for SEGA in pediatric patients (titrated to trough levels 5-15 ng/m L).. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between AURLUMYN and AFINITOR in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. AURLUMYN is classified as Category C. First trimester: Increased risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and limited human data. Second and third t. AFINITOR is classified as Category C. Pregnancy Category D. Positive evidence of human fetal risk. Based on its mechanism of action (mTOR inhibitor) and animal studies, AFINITOR (everolimus) is embryotoxic and fetotoxi. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
