依维莫司(everolimus,Zortress)口服片剂是一种口服的哺乳动物雷帕霉素靶蛋白(mTOR)抑制剂,临床上常用于预防肾移植和心脏移植手术后的排异反应.近年来发现它对晚期肾细胞癌具有较好疗效,可用于舒尼替尼或者索拉非尼治疗失败的肾癌患者。

免疫抑制剂(大环内酯类抗生素)
活性成分(S):
0.25mg的依维莫司,0.5毫克,0.75毫克;标签。
指示(S):
结合basiliximab诱导和低剂量的环孢素和皮质类固醇,在低中度免疫风险的肾移植患者的器官排斥反应的预防。
药理作用:
依维莫司结合的细胞质蛋白,FK506结合蛋白-12,形成一个复杂的结合并抑制哺乳动物雷帕霉素(mTOR)的目标。这种相互作用抑制P70 S6核糖体蛋白激酶的活性,导致核糖体S6蛋白磷酸化,随后的蛋白质合成和细胞增殖的抑制。这个动作,因此抑制抗原和白细胞介素(IL-2和IL-15)刺激T和B淋巴细胞的活化和增殖。
临床试验:
24个月,跨国公司,开放标签,随机试验,涉及到1.44克/ 833从头肾移植患者18-70岁,评估依维莫司1.5mg/day或3mg/day依维莫司,加上低剂量环孢素和皮质类固醇一天酚酸加标准剂量环孢素和皮质类固醇。在12个月,依维莫司1.5mg/day被证明是疗效失败(分别是25.3%和24.2%),定义为治疗活检证实的急性排斥反应,移植物丢失,死亡或损失媲美酚酸起来。此外,计算的平均肾小球滤过率(GFR)的依维莫司1.5mg/day和麦考酚酸在12个月(54.6mL/min和52.3mL/min,分别)相媲美。
两个多中心,双盲(前12个月),随机试验招收1171总从头肾移植患者相比everolimus的1.5mg/day和3mg/day的固定剂量与标准剂量环孢素和皮质类固醇联合霉酚酸酯2g/day和皮质类固醇。 12个月的GFR分析表明,增加肾功能不全的发生率都依维莫司组相比,霉酚酸酯在这两个试验组。因此,环孢素剂量应减少everolimus的组合使用时,和依维莫司谷浓度应调整,并保持在3,8ng/mL使用治疗药物监测。

Everolimus(也称为RAD001,SDZ-RAD,Afinitor,Certican,Zortress),是ripamycin(sirolimus)的40-O-(2-羟乙基)衍生物,作用机制类似ripamycin靶向抑制mTOR活性,表现出免疫抑制剂和抗血管生成特性[1]。Everolimus竞争性结合FKBP12(IC50=1.8-2.6 nM)从而抑制p70 S6激酶活化,进而阻断生长因子介导的T细胞,B细胞和VSMC细胞增殖,促使细胞周期停滞在G1期。Everolimus抑制多种体外培养人肿瘤细胞系和体内动物移植瘤的增殖[2]。Everolimus已处于多种人体肿瘤如乳腺癌,胃癌,肝细胞癌和淋巴瘤的III期临床实验阶段。Everolimus以药物名Afinitor,Certican或Zortress上市用于诊治其他药物治疗无效的晚期肾细胞癌(RCC)。
Manufacturer:
Novartis Pharmaceuticals Corp
Pharmacological Class:
Immunosuppressant (macrolide)
Active Ingredient(s):
Everolimus 0.25mg, 0.5mg, 0.75mg; tabs.
Indication(s):
Organ rejection prophylaxis in renal transplant patients with low-moderate immunologic risk, in combination with basiliximab induction and reduced doses of cyclosporine and corticosteroids.
Pharmacology:
Everolimus binds to the cytoplasmic protein, FK506 Binding Protein-12, forming a complex that binds to and inhibits the mammalian target of rapamycin (mTOR). This interaction inhibits p70 S6 ribosomal protein kinase activity, resulting in inhibition of ribosomal S6 protein phosphorylation, subsequent protein synthesis and cell proliferation. This action consequently inhibits antigenic and interleukin (IL-2 and IL-15) stimulated activation and proliferation of T and B lymphocytes.
Clinical Trials:
A 24-month, multinational, open-label, randomized trial, involving 833 de novo renal transplant patients 18–70 years of age, evaluated everolimus 1.5mg/day or everolimus 3mg/day plus reduced doses of cyclosporine and corticosteroids to 1.44g/day mycophenolic acid plus standard doses of cyclosporine and corticosteroids. At 12 months, everolimus 1.5mg/day was shown to be comparable to mycophenolic acid with respect to efficacy failure (25.3% and 24.2%, respectively), defined as treated biopsy-proven acute rejection, graft loss, death or loss to follow-up. Additionally, the calculated mean glomerular filtration rate (GFR) for everolimus 1.5mg/day and mycophenolic acid were comparable at month 12 (54.6mL/min and 52.3mL/min, respectively).
Two multicenter, double-blind (for first 12 months), randomized trials enrolling 1171 total de novo renal transplant patients compared fixed doses of everolimus 1.5mg/day and 3mg/day combined with standard doses of cyclosporine and corticosteroids to mycophenolate mofetil 2g/day and corticosteroids. The 12-month analysis of GFR demonstrated increased rates of renal impairment in both everolimus groups compared to the mycophenolate mofetil group in both trials. Therefore, cyclosporine doses should be reduced when used in combination with everolimus, and everolimus trough concentrations should be adjusted and maintained between 3 to 8ng/mL using therapeutic drug monitoring.
Legal Classification:
Rx
Adults:
Give as soon as possible after transplantation. Swallow whole. ≥18yrs: Initially 0.75mg every 12 hours (1.5mg/day) in combination with reduced dose cyclosporine. May adjust dose at 4–5 day intervals to achieve everolimus trough concentration target range: 3–8ng/mL. Moderate hepatic dysfunction: reduce daily dose by 1/2 the initial daily dose. Initiate oral prednisone as soon as oral medication is tolerated.
Children:
<18yrs: not recommended.
Contraindication(s):
Sirolimus allergy.
Warnings/Precautions:
Increased risk of infections, lymphomas and other malignancies (eg, skin). Avoid sun, UV light. High immunologic risk or prophylaxis in other organs: not established. Severe hepatic impairment or hereditary disorders (eg, galactose intolerance, Lapp lactase deficiency, glucose-galactose malabsorption): not recommended. Diabetes. Obtain everolimus and cyclosporine (see literature) whole blood concentrations periodically; and trough concentrations during dose adjustments. Monitor CBCs, renal function, urine protein, lipids, blood glucose, and for pneumonitis and infections. Pregnancy (Cat.C); use effective method of contraception during and up to 8 weeks after therapy. Nursing mothers: not recommended.
Interaction(s):

Potentiated by CYP3A4 and/or P-glycoprotein inhibitors; avoid strong inhibitors (eg, ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, ritonavir, grapefruit juice, digoxin); monitor and adjust dose with moderate inhibitors (eg, erythromycin, fluconazole, nicardipine, diltiazem, nelfinavir, indinavir, amprenavir), or CYP3A4 and P-glycoprotein substrate (eg, verapamil). Antagonized by CYP3A4 inducers (eg, carbamazepine, phenobarbital, phenytoin, efavirenz, nevirapine, St. John’s Wort); avoid strong inducers (eg, rifampin, rifabutin). Avoid simvastatin, lovastatin; monitor if used with atorvastatin or pravastatin. Caution with other nephrotoxic drugs, CYP3A4 or CYP2D6 substrates with a narrow therapeutic index.
Adverse Reaction(s):
Peripheral edema, GI upset, constipation, hypertension, anemia, infections (eg, UTI), hyperlipidemia, angioedema, malignancies (eg, lymphomas, skin), proteinuria, nephrotoxicity, graft thrombosis, delayed wound healing/dehiscence, polyoma virus infections (eg, BK virus-associated nephropathy), non-infectious pneumonitis (reduce or interrupt dose and/or manage with corticosteroids), thrombotic microangiopathy, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, new-onset diabetes post-transplant, male infertility.
