Everolimus Chemical Properties,Uses,Production

Overview

Everolimus is a derivative of Rapamycin(sirolimus), and works similarly to Rapamycin as an mTOR(mammalian target of rapamycin) inhibitor^[1-3]. It is currently used as an immunosuppressant to prevent rejection of organ transplants. In a similar fashion to other mTOR inhibitors, Everolimus takes effect solely on the mTORC1 protein and not on the mTORC2 protein^[1]. In transplantation medicine, it is marketed under the trade names Zortress(USA) and Certican(Europe)[4]. It has been also used for the treatment of tumors, being marketed as Afinitor(general tumours) and Votubia(tumours as a result of TSC) in oncology^{[5, 6]}.

Indications

Everolimus is indicated for the treatment of numerous diseases and disorders. It indicated for the treatment of the following cases including both tumors and organ transplantation:
Patients with advance kidney cancer^[7];
Postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer(advanced HR+ BC) in combination with exemestane, after failure of treatment with letrozole or anastrozole^[8-10];
Adult patients with progressive neuroendocrine tumors of pancreatic origin(PNET) with unresectable, locally advanced or metastatic disease^{[9, 10]};
Adult patients with advanced renal cell carcinoma(RCC) after failure of treatment with sunitinib or sorafenib;
Adult patients with renal angiomyolipoma and tuberous sclerosis complex(TSC), not requiring immediate surgery^[11];
Pediatric and adult patients with tuberous sclerosis complex(TSC) for the treatment of subependymal giant cell astrocytoma(SEGA) that requires therapeutic intervention but cannot be curatively resected^[12];
Adult and pediatric patients aged 2 years and older with Tuberous Sclerosis Complex(TSC)-associated partial-onset seizures^[10];
Preventing the organ rejection during/after renal and liver transplantation^{[14, 15]};
Progressive, well-differentiated non-functional, neuroendocrine tumors[NET] of gastrointestinal(GI) or lung origin with unresectable, locally advanced or metastatic disease^[16].

Mode of action

The mammalian target of rapamycin(mTOR) pathway is one of the most clinically important molecular signalling networks to emerge over the past decade. It is the protein kinase at the core of this intricate and continually evolving pathway, controls cellular growth and behavior, impacting vital processes from immune reactivity to cancer progression^{[17, 18]}. Everolimus is an mTOR inhibitor that binds with high affinity to the FK506 binding protein-12(FKBP-12), thereby forming a drug complex that inhibits the activation of mTOR^[19-20]. This inhibition reduces the activity of effectors downstream, which leads to a blockage in the progression of cells from G1 into S phase, and subsequently inducing cell growth arrest and apoptosis. Everolimus also inhibits the expression of hypoxia-inducible factor, leading to a decrease in the expression of vascular endothelial growth factor^{[19, 20]}. The result of everolimus inhibition of mTOR is a reduction in cell proliferation, angiogenesis, and glucose uptake. Since highly expression of mTOR is an important factor that promoting the cancer, blocking mTOR by Everolimus can effectively treat some kinds of cancer and the organ rejection due to immune response during/after organ transplantation^{[21, 22]}.

Pharmacokinetics

Oral everolimus is absorbed rapidly, and reaches peak concentration after 1.3–1.8 hours. Steady state is reached within 7 days, and steady-state peak and trough concentrations, and area under the concentration-time curve (AUC), are proportional to dosage. In adults, everolimus pharmacokinetic characteristics do not differ according to age, weight or sex, but bodyweight-adjusted dosages are necessary in children.

Adverse reactions

Some serious adverse reactions associated with Everolimus include non-infection pneumonitis, infections, severe hypersensitivity reactions, angioedema with concomitant use of ACE inhibitors, stomatitis, renal failure, impaired wound healing, metabolic disorders and myelosuppression^[10]. Various common side effects include Bloating or swelling of the face, arms, hands, lower legs, or fee bloody nose, chest pain or tightness, chills, cough, decreased weight, diarrhea, difficult or labored breathing, difficulty with swallowing, fever, general feeling of discomfort or illness, hoarseness, lower back or side pain, painful or difficult urination, rapid weight gain, sores, ulcers, or white spots on the lips, tongue, or inside the mouth and tingling of the hands or feet^[23]. Less common side effects include bleeding gums, bloody urine, blurred vision, burning, crawling, itching, numbness, prickling, or tingling feelings, coughing up blood, extreme tiredness or weakness, fast, pounding, or irregular heartbeat or pulse, increased thirst or urination, irregular breathing, loss of appetite, nausea, nervousness, nosebleeds, prolonged bleeding from cuts, red or black, tarry stools, red or dark brown urine, slow heartbeat, stomach ache, sweating, unusual tiredness or weakness and vomiting^[23].

Warning and precautions

People who are allergic to Everolimus should be disabled. Since it can increase your risk of serious infections or getting certain cancers, such as lymphoma or skin cancer. The patients should ask their doctor about the specific risk^{[10, 23]}.
Patients who have the following conditions should consult for doctor for advice before administration: problem in digesting lactose or galactose(sugar); high cholesterol or triglycerides; liver disease; a heart transplantation; or skin cancer in them or their family members^[23].
Since it may harm the unborn baby as well as affect fertility(the capability to have children), women should take effective birth control during administration of Everolimus and for at least eight weeks after stopping drugs. Should consult the doctor for advice if you want to or has become pregnant. It may also affect the fertility of men as well. It is generally not recommended to have breast-feed during the administration of Everolimus for women^{[10, 23]}.

Description

Everolimus, an oral immunosuppressant for the treatment of kidney and heart transplant rejection, is the 40-O-(2-hydroxyethyl) derivative of rapamycin. It has immunosuppressive properties similar to those of rapamycin, but with improved pharmacokinetic profile. In addition, the 40-O-(2-hydroxyethyl) group alters the physico-chemical properties of the macrolide to allow galenic formulation. Everolimus is prepared in a two-step semisynthesis starting from rapamycin, by alkylation of the 40-hydroxyl group with t-butyldimethylsilyloxyethyl triflate and subsequent cleavage of the silyl protecting group. Everolimus, like rapamycin, is a proliferation signal inhibitor that exerts its immunosuppressive effect by inhibiting the activation of p70 S6 kinase, thereby blocking growth factor-driven proliferation of T cells, B cells and vascular smooth muscle cells, and arresting cell cycle at the G1 phase. Inhibition of p70 S6 kinase activation by everolimus and rapamycin is mediated by their binding to FKBP12 (FK506 binding-protein 12). Everolimus inhibits FK506 binding to FKBP12 with an IC₅₀ of 1.8–2.6 nM, and it is about 3- to 5-fold less potent than rapamycin (IC₅₀=0.4–0.9 nM). The in vitro immunosuppressive activity of everolimus is also slightly less than that of rapamycin as demonstrated in a mixed lymphocyte reaction (MLR) assay (IC₅₀=0.2–1.6 nM versus 0.07–0.5 nM, respectively) and in antigen-specific human helper T-cell clones (IC₅₀=0.05–0.17nM versus 0.014–0.37nM, respectively). However, the in vivo immunosuppressive activity of oral everolimus 1–5 mg/ kg/day is similar to that of rapamycin at equivalent doses in rat models of renal or cardiac transplantation, localized graft-versus-host disease, and autoimmune glomerulonephritis. The recommended dosage of everolimus is 0.75 mg twice daily, and it is used in combination with cyclosporine microemulsion and corticosteroids. Following oral dosing, the peak concentration (C_max) of everolimus is estimated between 1.5 to 2 hours, and steady state is achieved within 4 days. The terminal elimination half-life is 21 to 35 hours. By comparison, rapamycin has a longer elimination half-life (60 hours) and longer time to reach steady state (7 to 14 days). Consequently, rapamycin treatment requires a large loading dose, followed by once daily maintenance dose, whereas everolimus is administered twice daily but without the need of a loading dose. Everolimus is extensively metabolized, primarily by CYP3A4. Approximately 80% of the dose is excreted in the feces and about 5% in the urine. In clinical trials with adult cardiac transplant recipients, oral everolimus 0.75 or 1.5 mg twice daily significantly reduced the incidence of efficacy failure as well as cardiac allograft vasculopathy (CAV) up to 2 years after transplantation as compared with azathioprene 1–3 mg/kg/day. However, graft and patient survival rates at 1 year were similar in patients receiving everolimus and azathioprene. In trials involving renal transplant recipients, the combined incidence of biopsy-confirmed acute rejection, graft loss, death, or loss to follow-up was similar in patients receiving everolimus 1.5 or 3 mg/day or mycophenolate mofetil 2 g/day up to 3 years after transplantation. Everolimus was well tolerated in transplant patients. The incidence of viral infection including cytomegalovirus (CMV) was reduced in comparison to azathioprene and mycophenolate mofetil, but bacterial infections were more frequent. Main adverse events associated with everolimus were thrombocytopenia, leucopenia, and elevated serum lipids and creatinine.
