Overview
11. DESCRIPTION Everolimus Tablets and Everolimus Tablets for Oral Suspension are kinase inhibitors. The chemical name of everolimus is (1R,9S,12S,15R,16E,18R,19R,21R,23S,24E,26E,28E,30S,32S,35R)-1,18-dihydroxy-12-{(1R)-2-[(1S,3R,4R)-4-(2-hydroxyethoxy)-3-methoxycyclohexyl]-1-methylethyl}-19,30-dimethoxy-15,17,21,23,29,35-hexamethyl-11,36-dioxa-4-aza-tricyclo[30.3.1.
Mechanism of Action
12. CLINICAL PHARMACOLOGY 12.1 Mechanism of Action 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.
Indications
- 1. INDICATIONS AND USAGE Everolimus tablets are a kinase inhibitor indicated for the treatment of: Postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer in combination with exemestane after failure of treatment with letrozole or anastrozole. ( 1.1 ) Adults with progressive neuroendocrine tumors of pancreatic origin (PNET) and adults with progressive, well-differentiated, non-functional neuroendocrine tumors (NET) of gastrointestinal (GI) or lung origin that are unresectable, locally advanced or metastatic.

Dosage
2. DOSAGE AND ADMINISTRATION Do not combine everolimus tablets 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 ) Breast Cancer: 10 mg orally once daily. ( 2.2 ) NET: 10 mg orally once daily. ( 2.3 ) RCC: 10 mg orally once daily. ( 2.4 ) TSC-Associated Renal Angiomyolipoma: 10 mg orally once daily. ( 2.5 ) TSC-Associated SEGA: 4.5 mg/m 2 orally once daily; adjust dose to attain trough concentrations of 5-15 ng/mL.
