Everolimus is indicated in advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer (Advanced HR+ BC), Advanced Neuroendocrine Tumors (NET); Advanced Renal Cell Carcinoma (RCC); Renal Angiomyolipoma With Tuberous Sclerosis Complex (TSC); Subependymal Giant Cell Astrocytoma (SEGA) With Tuberous Sclerosis Complex (TSC) In combination with ciclosporin for microemulsion & corticosteroids for the prophylaxis of organ rejection in adult patients at low to moderate immunological risk receiving an allogeneic renal or cardiac transplant. In combination with tacrolimus & corticosteroids for the prophylaxis of organ rejection in patients receiving hepatic transplant.
Everolimus is an inhibitor of mammalian target of rapamycin (mTOR), a serine-threonine kinase, downstream of the PI3K/AKT pathway. The mTOR pathway is dysregulated in several human cancers and in tuberous sclerosis complex (TSC). Everolimus binds to an intracellular protein, FKBP-12, resulting in an inhibitory complex formation with mTOR complex 1 (mTORC1) and thus inhibition of mTOR kinase activity. Everolimus reduced the activity of S6 ribosomal protein kinase (S6K1) and eukaryotic initiation factor 4E-binding protein (4E-BP1), downstream effectors of mTOR, involved in protein synthesis. S6K1 is a substrate of mTORC1 and phosphorylates the activation domain 1 of the estrogen receptor which results in ligand-independent activation of the receptor. In addition, everolimus inhibited the expression of hypoxia-inducible factor (e.g., HIF-1) and reduced the expression of vascular endothelial growth factor (VEGF). Inhibition of mTOR by everolimus has been shown to reduce cell proliferation, angiogenesis, and glucose uptake in in vitro and/or in vivo studies.
Constitutive activation of the PI3K/Akt/mTOR pathway can contribute to endocrine resistance in breast cancer. In vitro studies show that estrogen-dependent and HER2+ breast cancer cells are sensitive to the inhibitory effects of everolimus, and that combination treatment with everolimus and Akt, HER2, or aromatase inhibitors enhances the anti-tumor activity of everolimus in a synergistic manner.
General kidney & heart transplant population: Initially 0.75 mg bd administered as soon as possible after transplantation. Hepatic transplant: 1 mg bd with initial dose starting 4 wk after transplantation. Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer, Advanced NET, Advanced RCC, And Renal Angiomyolipoma With TSC: The recommended dose is 10 mg, to be taken once daily at the same time every day. Administer either consistently with food or consistently without food. Everolimus Tablets should be swallowed whole with a glass of water. Do not break or crush tablets. Continue treatment until disease progression or unacceptable toxicity occurs.
P-gp and strong CYP3A4 inhibitors: Avoid concomitant use.
P-gp and moderate CYP3A4 inhibitors: Reduce the dose as recommended.
P-gp and strong CYP3A4 inducers: Increase the dose as recommended.
Patients with hypersensitivity to the active substance, to other rapamycin derivatives, or to any of the excipients. Hypersensitivity reactions manifested by symptoms including, but not limited to, anaphylaxis, dyspnea, flushing, chest pain, or angioedema (e.g., swelling of the airways or tongue, with or without respiratory impairment) have been observed with everolimus and other rapamycin derivatives.
Stomatitis, Constipation, Infections, Asthenia, Fatigue, Cough, Diarrhea, Rash, Anemia, Nausea, Anorexia, Edema, peripheral, Dyspnea, Pyrexia, Vomiting, Headache, Epistaxis, Decreased lymphocytes, Grade 3, Increased glucose, Grade 3, Pneumonitis, Pruritus, Dry skin, Decreased Hgb, Grade 3, Menstrual irregularities, Dysgeusia, Hypertension, Hemorrhage, Tachycardia, CHF.
Pregnancy Category D. There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Lactation: Distribution into breast milk is unknown; not recommended.
Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.
