舒尼替尼能抑制多个受体酪氨酸激酶(RTK),其中某些受体酪氨酸激酶参与肿瘤生长、病理性血管形成和肿瘤转移的过程。 舒尼替尼对血小板源生长因子受体(PDGFRα和PDGFRβ)、血管内皮细胞生长因子(VEGFR1、VEGFR2和ⅦGFR3)、干细胞因子受体(KIT)、Fms样酪氨酸激酶3(FLT3)、1型集落刺激因子受体(CSF-1R)和胶质细胞衍生的神经营养因子受体(RET)等活性均具有抑制作用,其主要代谢产物与舒尼替尼活性相似。
药代动力学
一般在口服给药后6-12小时达最大血浆浓度。进食对其生物利用度无影响。 舒尼替尼及其主要代谢物的血浆蛋白结合率分别为95%和90%。 舒尼替尼和主要活性代谢物的终末半衰期分别为40-60小时和80-110小时。每日重复给药后,舒尼替尼蓄积3-4倍,而其主要代谢物蓄积7-10倍,在10-14天内达稳态浓度。 剂量的61%通过粪便排泄,肾脏排泄的药物和代谢物约占剂量的16%。 体重、肌酐清除率、人种、性别或ECOG体力状态评分对舒尼替尼或其活性代谢物的药代动力学没有临床相关性影响。 适应症
癌细胞已发生转移或对甲磺酸伊马替尼耐受的胃肠道间质瘤(GIST)和采用细胞因子疗法无效的转移性肾细胞癌(MRCC)。
临床研究
对312例癌细胞已发生转移或对甲磺酸伊马替尼耐受胃肠道间质瘤患者的研究中,在肿瘤进展时间(TTP)和无进展生存期(PFS)方面stmitinib显著优于安慰剂,其中stmitinib组TTP为27.3周,安慰剂组TTP为6.4周;sunitinib组PFS为24.1周,安慰剂组PFS为6.0周。说明stmitinib能延缓胃肠道间质瘤的生长速度。
对750例转移性肾细胞癌的临床试验显示,Stmitinib更能有效阻止疾病进展,并能缩小肾细胞肿瘤的尺寸,治疗效果优于干扰素(免疫疗法)。Sunitinib组患者中位PFS达到11个月,而a一干扰素治疗组的中位PFS只有5个月;Stmitinib的客观缓解率(ORR)是干扰素的5倍(28% :5%)。Sunitinib的总体耐受性好,中断治疗率低于 干扰素。 另外,对其他工期和Ⅱ期临床试验中,使用过stmitinib的患者随访数据显示,患者的总生存时间已延长至20个月,大大超过预期时间。
用法用量
治疗胃肠间质瘤和晚期肾细胞癌的推荐剂量是50mg,每日一次,口服;服药4周,停药2周(4/2给药方案)。与食物同服或不同服均可。 剂量调整: 建议根据药物在个体中的安全性和耐受性情况,以12.5mg为梯度单位增加或减少剂量。 CYP3A4强抑制剂(如酮康唑)可增加本品的血浆浓度。如必须合并使用时,应考虑降低本品的剂量,最小可至37.5mg,每日一次。 CYP3A4诱导剂(如利福平)可降低本品的血浆浓度。如必须合并使用时,应考虑增加本品的剂量,最大可至87.5mg,每日一次。 任何疑问,请遵医嘱! 不良反应

舒尼替尼(Sunitinib,Sutent)是一种新型多靶向性的治疗肿瘤的口服药物。舒尼替尼的首要开发目标为,用于治疗对标准疗法没有响应或不能耐受之胃肠道基质肿瘤和转移性肾细胞癌。舒尼替尼能选择性地靶向某些蛋白的受体,后者被认为在肿瘤生长过程中起着一种分子开关样的作用。舒尼替尼的上述适应证已在美国获得了FDA授予的“快通道”审批地位。 舒尼替尼是一类能够选择性地靶向多种受体酪氨酸激酶的新型药物中的第一个药物。抑制受体酪氨酸激酶被认为可经阻断肿瘤生长所需的血液和营养物质供给而“饿死”肿瘤并具同时杀死肿瘤细胞活性,即舒尼替尼结合了中止向肿瘤细胞供应血液的抗血管形成和直接攻击肿瘤细胞的抗肿瘤这两种作用机制。 舒尼替尼可能代表了新一轮靶向疗法的问世,它既能直接攻击肿瘤、又无常规化疗的毒副反应,其临床优势是显而易见的。舒尼替尼已于2005年8月在美提出了新药申请;同年9月又向欧美药政当局提交了批准申请。辉瑞公司目前正在等待欧美批准舒尼替尼用于标准治疗无效或不能耐受的胃肠道基质肿瘤和肾细胞癌患者。Ⅲ期临床试验证实,舒尼替尼能够大大延长已对伊马替尼治疗耐药或不能耐受的胃肠道基质肿瘤患者的肿瘤进展时间(分别为6.3个月对安慰剂组的1.5个月),并显著性降低他们50%的死亡风险。舒尼替尼也已在用于治疗转移性乳腺癌和神经内分泌肿瘤等的Ⅱ期临床试验中显现出令人鼓舞的结果。舒尼替尼现正在进行单用或合用其他抗肿瘤药物用于治疗许多其他类型实体瘤,包括乳腺癌、肺癌、前列腺癌和结肠直肠癌等的大量研究。 舒尼替尼(Sunitinib,Sutent)是一类能够选择性地靶向针对多种受体酪氨酸激酶的新型药物中的第一个药物。它通过阻断肿瘤生长所需的血液和营养物质供给和直接攻击肿瘤细胞这两种作用机制来对抗肿瘤,因此其临床优势是显而易见的。它可能代表了新一轮靶向疗法的问世。 【治疗转移性肾细胞癌】 已有非对照研究显示舒尼替尼对转移性肾细胞癌(mRCC)患者有效。2006年ASCO会议上美国纽约Memorial Sloan-Kettering癌症中心Motzer等报告,在一项针对mRCC患者的随机Ⅲ期试验中,和干扰素(IFN)-α相比,舒尼替尼作为一线疗法证实对患者无进展生存期(PFS)和目标缓解率(ORR)都有明显改善作用。第三方评估的舒尼替尼组的中位无进展生存期(11个月)显著长于IFN-α 组(5个月),相应的风险比是0.42(95%可信区间为0.32~0.54,P<0.001)。 在2007年ASCO会议上,Motzer等提供了来自这一试验的最新结果和有关预后因素的一个分析报告。研究纳入未经治疗的患有透明细胞mRCC的750例患者,并按1∶1的比例(舒尼替尼与IFN-α组均为375例)将患者随机分组以便接受舒尼替尼(每天50 mg 口服,连用4周,休息2周,6周为1个周期)或IFN-α(9 MU 皮下注射,每周3次)治疗。主要终点是PFS。治疗的中位持续时间是舒尼替尼11个月,IFN-α 4个月。 研究者评估的最新客观肿瘤缓解率(ORR)是:舒尼替尼组44% (95% CI:39~49),IFN-α组 11%(95% CI:8~15)。舒尼替尼组4例完全缓解,IFN-α组 2例。舒尼替尼组中位PFS为10.8个月(95%CI:10.6~12.6),IFN-α组为 4.1个月(95% CI:3.8~5.3) (图1)。经舒尼替尼治疗的0风险因子的患者(n=112)中位PFS 是14.8个月(95% CI:13.0~19.3);具有1个风险因子的患者(n=169)则是10.8个月(95% CI:8.7~12.6);≥2个风险因子的患者(n=94)则是8.0个月(95% CI:4.0~8.6)。 在所有的美国癌症中心纽约纪念医院(MSKCC)预后因子组中均可发现舒尼替尼有PFS获益(HR= 0.488;95% CI:0.406~0.586)。舒尼替尼组中预测更长PFS的基线特征(通过研究者评估)是血红蛋白处于正常值低限(P=0.0043),校正钙=10 mg/dl (P=0.001),ECOG评分为0(P=0.0005),转移灶数量为0 或 1 (P=0.0064),从诊断到治疗的时间为1年(P=0.0002)。 【治疗胃肠道间质瘤】 会议上还报告了舒尼替尼在许多其他类型肿瘤的治疗上所显现出的令人鼓舞的结果。在伊马替尼抵抗或无法耐受的胃肠道间质瘤(GIST)患者中,初步研究显示:循环中KIT水平可能是TTP的一个标记,可溶性KIT(sKIT)水平的降低可能预示着伊马替尼和舒尼替尼治疗有效。研究中期分析显示,舒尼替尼组与安慰剂组相比TTP显著延长,中位TTP为27.3周对6.4周(HR=0.33,P<0.0001)(图2)。舒尼替尼持续每日给药似乎是伊马替尼抵抗或无法耐受的GIST患者的一个安全且有效的给药策略。 【治疗非小细胞肺癌】 一项Ⅱ期试验显示,对化疗无效的晚期非小细胞肺癌(NSCLC)患者,舒尼替尼单药治疗能缩小肿瘤或阻止肿瘤生长,提示其有望在肺癌治疗中占一席之地。既往接受过治疗的患者接受舒尼替尼连续给药方案治疗时,安全性可接受。同时有初步的有效性证据:1例PR,中位PFS 12.1周。 【治疗肝细胞癌】 有研究者设计了一个Ⅱ期临床试验来评估舒尼替尼治疗进展期肝细胞肝癌(HCC)的有效性和毒性。结果显示,在密切监护下,患者接受目前的剂量(37.5 mg口服,每天一次治疗,连用4周休息2周,6周为一个周期)是安全的。初步观察到抗肿瘤活性证据,并且治疗后血管源性参数及血中标志物发生了改变。 |
