生物活性&实验参考方法
靶点
MEK1 (IC50 = 4.2 nM)
Mitogen-activated protein kinase kinase 1 (MEK1) and MEK2, serine/threonine kinases in the MAPK pathway. For Cobimetinib (GDC-0973, RG-7420, XL-518), the potency data from [1] were: MEK1 (IC50 = 4.2 nM, Ki = 0.9 nM), MEK2 (IC50 = 10.3 nM) via HTRF kinase assay. It showed no inhibition of 38 other kinases (e.g., ERK1, JNK, p38, PI3K) at 1 μM, confirming MEK1/2 selectivity [1]
体外研究 (In Vitro)
Cobimetinib 在多种肿瘤类型中显示出强大的细胞生长抑制活性,特别是在 BRAF 或 KRAS 突变癌细胞系中。与 GDC-0941 联合使用时,GDC-0973 会导致 888MEL 和 A2058 细胞失去活力、抑制某些途径并发生更多细胞凋亡。 [1]在所有 BRAFV600E 系中,GDC-0973 和维莫非尼的共同给药显着增加细胞膜上 GLUT-1 水平的降低。 [2]
癌细胞增殖与MAPK通路抑制:在BRAF V600E突变细胞系(A375:黑色素瘤,Colo205:结直肠癌)中,Cobimetinib(0.001 μM–10 μM)抑制增殖,MTT法(72小时)测得IC50为A375 0.02 μM、Colo205 0.05 μM;在KRAS突变细胞(HCT116:结直肠癌)中,IC50=0.12 μM。Western blot显示A375细胞经0.1 μM处理2小时后p-ERK减少95%,0.5 μM处理48小时后切割型caspase-3增加3.2倍 [1]
- 协同活性:在A375细胞中与BRAF抑制剂维莫非尼(0.1 μM)联用,Cobimetinib(0.01 μM)显示协同增殖抑制(联合指数CI=0.4),凋亡率达60%(Annexin V染色,48小时),而单药组凋亡率均为25% [1]
体内研究 (In Vivo)
Cobimetinib(10 mg/kg,口服)与 GDC-0973 和 GDC-0941 一起在患有 BRAFV600E 和 KRAS 突变肿瘤的小鼠中表现出更好的抗肿瘤功效。 [1]组合 GDC-0973 和 GDC-0941 可降低耐药 A375 异种移植小鼠体内己糖激酶 II、c-RAF、Ksr 和 p-MEK 蛋白的水平。 [2]
黑色素瘤异种移植模型:6周龄雌性裸鼠接种A375细胞,随机分为4组(每组n=8):溶媒组、Cobimetinib 10 mg/kg组、维莫非尼50 mg/kg组、联合组。Cobimetinib口服每日一次,维莫非尼口服每日两次,连续21天。肿瘤体积减少率:单独用药组55%(Cobimetinib)、60%(维莫非尼),联合组85%;肿瘤重量减少率:单独用药组50%,联合组75%。免疫组化显示联合组p-ERK减少80%、Ki-67减少70% [1]
- 结直肠癌异种移植模型:7周龄雄性裸鼠接种HCT116细胞,用Cobimetinib 20 mg/kg(口服每日一次)处理28天。肿瘤体积减少65%,血清肿瘤标志物CEA从600 ng/mL降至220 ng/mL [1]
- 体内PET成像与分布:8周龄雄性CD-1小鼠静脉注射[¹¹C]标记的Cobimetinib(10 MBq/kg),0.5–4小时PET成像显示:肝脏放射性最高(1小时5.2 %ID/g),肾脏次之(1小时3.8 %ID/g),A375异种移植瘤摄取为1小时1.2 %ID/g;2小时时肿瘤/肌肉放射性比值为3.5 [2]
酶活实验

细胞实验
对于888MEL和A2058细胞,cobimetinib (GDC-0973)的EC50浓度分别为0.2 M和10 M。将 EC50 浓度的 MEK 和 PI3K 抑制剂应用于黑色素瘤细胞 24 小时(888MEL:0.05 M GDC-0973、2.5 M GDC-0941;A2058:2.5 M GDC-0973、2.5 M GDC-0941)。在 A375 细胞中,cobimetinib (100 nM) 在具有组成型 MAPK 激活的黑色素瘤中引起的细胞死亡受到线粒体 OXPHOS 的限制。
癌细胞增殖与凋亡实验:A375/HCT116/Colo205细胞以5×10³个细胞/孔接种于96孔板,用Cobimetinib(0.001 μM–10 μM)单独或联合维莫非尼(0.1 μM)处理72小时。加入5 mg/mL MTT试剂孵育4小时,DMSO溶解甲臜结晶后,检测570 nm吸光度计算IC50。凋亡实验中,A375细胞(2×10⁵个细胞/孔,6孔板)用0.5 μM Cobimetinib(±维莫非尼)处理48小时,Annexin V-FITC/PI染色,流式细胞术分析 [1]

将500万个WM-266-4黑色素瘤细胞皮内植入雌性NCR裸鼠后侧腹部。细胞悬浮于Hank's平衡盐溶液中。肿瘤体积约为100至120 mm³的异种移植小鼠在植入后第11或13天随机分为4个单剂量组和4个多剂量组。单剂量组小鼠在随机分组后一天分别口服单剂量的Cobimetinib(GDC-0973,以游离碱当量表示)、赋形剂(注射用水USP)、1、3或10 mg/kg剂量。多剂量组小鼠连续14天每日口服GDC-0973、赋形剂(注射用水USP)或两者联合用药。在第1天(单剂量组)或第14天(多剂量组),从安乐死的实验小鼠中采集给药前以及给药后2、4、8、16、24、72和168小时的血浆和肿瘤样本(每个时间点n=3)。样本保存在80°C直至分析。采用液相色谱/串联质谱法(LC/MS-MS)测定肿瘤裂解液和血浆中GDC-0973的浓度。该检测方法的动态范围为0.004至35 μM。
A375黑色素瘤异种移植方案:将5×10⁶个A375细胞皮下植入6周龄雌性裸鼠体内。当肿瘤体积达到约 100 mm³ 时,将 Cobimetinib 溶解于 0.5% 甲基纤维素 + 0.1% Tween 80 溶液中(口服,10 mg/kg,每日一次),将 vemurafenib 溶解于 0.5% 羟丙基甲基纤维素溶液中(口服,50 mg/kg,每日两次),持续给药 21 天。每 3 天测量一次肿瘤体积(长×宽²/2);于第 21 天处死小鼠,并对肿瘤进行 p-ERK/Ki-67 免疫组化染色 [1]

药代性质 (ADME/PK)
吸收、分布和排泄
癌症患者每日口服一次 60 mg 后,达到血浆峰浓度的中位时间 (Tmax) 为 2.4 小时(范围:1-24 小时),稳态 AUC0-24h 的几何平均值为 4340 ng∙h/mL(变异系数 61%),Cmax 为 273 ng/mL(变异系数 60%)。在健康受试者中,COTELLIC 的绝对生物利用度为 46%(90% 置信区间:40%,53%)。对健康受试者单次服用 20 mg COTELLIC 后,高脂餐(约含 150 卡路里蛋白质、250 卡路里碳水化合物和 500-600 卡路里脂肪)对 cobimetinib 的 AUC 和 Cmax 无影响。
单次口服 20 mg 放射性标记的 cobimetinib 后,76% 的剂量从粪便中回收(其中 6.6% 为原药),17.8% 的剂量从尿液中回收(其中 1.6% 为原药)。
基于群体药代动力学分析,癌症患者的表观分布容积估计为 806 L。
癌症患者每日口服一次 60 mg COTELLIC 后,平均表观清除率 (CL/F) 为 13.8 L/h(变异系数 61%)。
代谢/代谢物
考比替尼主要通过CYP3A氧化和UGT2B7葡萄糖醛酸化代谢,不生成主要代谢物。
生物半衰期
癌症患者每日口服一次60 mg考比替尼后,平均消除半衰期(t1/2)为44小时(范围:23-70小时)。
大鼠体内药代动力学:雄性Sprague-Dawley大鼠(8周龄)口服10 mg/kg考比替尼:口服生物利用度=50%,Cmax=3.8 μM,Tmax=1.0小时,末端t₁/₂=5.2小时。静脉注射剂量(2 mg/kg):CL = 7.6 mL/min/kg,Vss = 0.9 L/kg [1]
- 人血浆蛋白结合率:99%(平衡透析,[1])
- 体内分布(小鼠):[¹¹C]-考比替尼(10 MBq/kg,静脉注射)显示肝脏(1 小时时 5.2 %ID/g)> 肾脏(3.8 %ID/g)> 肿瘤(1.2 %ID/g)> 肌肉(0.3 %ID/g)放射性。放射性从血液中清除的半衰期为 t₁/₂ = 2.1 小时 [2]
毒性/毒理 (Toxicokinetics/TK)
肝毒性
在维莫非尼治疗期间,血清转氨酶和碱性磷酸酶水平升高较为常见,当与考比替尼联合用药时更为常见。26%至70%的治疗患者会出现肝功能异常,6%至12%的患者ALT值超过正常值上限(ULN)的5倍。在考比替尼和维莫非尼的临床试验中,也曾报道过出现临床表现明显的肝损伤伴黄疸的病例,但这些病例的临床特征、病程和结局尚未详细描述。在考比替尼的初始安全性评估中,至少包含一例出现肝细胞损伤伴黄疸的病例。MAPK通路抑制剂作为一类药物,通常与短暂的血清酶升高相关,较少情况下会引起临床表现明显的肝损伤,但其临床特征尚未描述,与考比替尼的关联也未明确。对于既往存在肝硬化或因肝肿瘤负荷导致肝功能损害的患者,使用蛋白激酶抑制剂后发生临床显著肝损伤和肝功能衰竭的风险增加。
可能性评分:D(可能导致临床明显的肝损伤)。
妊娠和哺乳期影响
◉ 哺乳期用药概述
目前尚无关于哺乳期使用考比替尼的临床信息。由于考比替尼与血浆蛋白的结合率高达90%,因此其在乳汁中的含量可能较低。然而,其半衰期约为44小时,因此可能在婴儿体内蓄积。制造商建议在接受考比替尼治疗期间以及末次给药后 2 周内停止母乳喂养。

◉ 对泌乳和母乳的影响
截至修订日期,未找到相关的已发表信息。
蛋白结合
考比替尼在体外与人血浆蛋白的结合率为 95%,且与药物浓度无关。
体外细胞毒性:在正常人外周血单核细胞 (PBMC) 中,考比替尼(浓度高达 10 μM,作用 72 小时)的存活率 > 85%,表明其非特异性毒性较低 [1]
- 急性体内毒性:在接受考比替尼 10 mg/kg(口服,28 天)治疗的大鼠中,未观察到明显的体重减轻、嗜睡或血清异常。检测了ALT/AST/肌酐水平。肝脏/肾脏组织学检查未见炎症或坏死[1]

其他信息
药效学
考比替尼是一种可逆性丝裂原活化蛋白激酶1 (MAPK)/细胞外信号调节激酶1 (MEK1) 和MEK2抑制剂。临床前研究表明,该药物能有效抑制携带BRAF突变的肿瘤细胞的生长,而BRAF突变与多种肿瘤类型相关。MEK1是一种苏氨酸酪氨酸激酶,也是RAS/RAF/MEK/ERK信号通路的关键组成部分,该通路在人类肿瘤中经常被激活。MEK1对于传递来自多种受体酪氨酸激酶的促生长信号至关重要。由于BRAF抑制剂的临床疗效受限于固有耐药性和获得性耐药性,考比替尼通常与维莫非尼联合使用。 MAPK 通路的重新激活是 BRAF 突变型黑色素瘤治疗失败的主要原因,约 80% 的黑色素瘤肿瘤由于 MAPK 信号的重新激活而对 BRAF 抑制剂产生耐药性。 BRAF抑制剂耐药的肿瘤细胞对MEK抑制剂敏感,因此,考比替尼和维莫非尼可同时抑制BRAF及其下游靶点MEK。
考比替尼(GDC-0973、RG-7420、XL-518)是一种强效、选择性的MEK1/2抑制剂,已获批与维莫非尼联合用于治疗BRAF V600E/K突变型不可切除/转移性黑色素瘤[1]
- 其作用机制包括与MEK1/2的变构位点结合(非ATP竞争性),稳定其非活性构象并阻断ERK磷酸化,与BRAF抑制剂联合使用可产生协同效应,克服耐药性[1]
- [¹¹C]标记的考比替尼可进行非侵入性PET成像,用于体内分布评估,支持癌症患者的临床药代动力学评估和剂量优化[2]
