简介

凡德他尼(vandetanib)是一种合成的苯胺喹唑啉化合物,被称“二代易瑞沙”,为口服的小分子多靶点酪酸激酶抑制剂(TKI),可同时作用于肿瘤细胞EGFR、VEGFR和RET酪氨酸激酶,还可选择性的抑制其他的酪氨酸激酶,以及丝氨酸/苏氨酸激酶。

Ⅰ期临床研究显示剂量限制性毒性为腹泻、高血压和皮疹。常见的毒副作用是腹泻、皮疹、恶心、呕吐以及无症状的QT间期延长。其毒副作用与剂量相关,在<300mg/d时,病人耐受性良好,最大耐受剂量(MTD)为300mg。

Ⅱ期临床研究涉及的病种很多。目前我国正在进行凡德他尼治疗NSCLC的临床试验。

1. 治疗晚期NSCLC(非小细胞肺癌)003号研究比较了凡德他尼 300 mg/d和吉非替尼250mg/d对一线或二线化疗失败的168例晚期NSCLC病人的疗效,与吉非替尼相比,凡德他尼明显地增加了有效率和延长了疾病无进展生存时间,分别为8%和1%,11.9周和8.1周,(P=0.011)。在临床试验中如果病人病情进展或不能耐受毒性,允许其改变治疗方案。

试验结果表明,用吉非替尼代替凡德他尼的病人疾病控制率为14%,而用凡德他尼代替吉非替尼的病人疾病控制率达到32%,预计中位总生存期由凡德他尼→吉非替尼为6.1个月,而由吉非替尼→凡德他尼为7.4个月。0007号研究正在进行中,目的是评价凡德他尼联合紫杉醇(200mg/m2)+卡铂(AUC=6)一线治疗ⅢB-IV期NSCLC的疗效。初步试验结果显示,凡德他尼可同时联合传统的化疗药物治疗NSCLC,没有明显增加3~4度的不良反应。

2. 治疗晚期乳腺癌46例,既往接受紫杉醇+蒽环类化疗失败的转移性乳癌患者,接受凡德他尼(100 mg或300mg),44例可评价的患者中未见客观疗效,2组病人各有1例病情稳定(SD)≥24周,作者认为单药凡德他尼治疗复发耐药的乳腺癌疗效有限,但耐受性良好。

3. 治疗晚期多发性骨髓瘤,18例化疗或造血干细胞移植治疗失败的多发性骨髓瘤患者,口服凡德他尼(100mg)3~29.4周,球蛋白或尿M蛋白未见改善,毒副作用可耐受,常见的毒副作用包括恶心、呕吐、腹泻、皮疹、皮肤瘙痒、感觉障碍等,但未见明确的QT间期改变。

4. 治疗甲状腺癌甲状腺髓样癌发病率低,具有遗传性,无论放射治疗、联合化疗抑或内分泌治疗效果不佳,预后差。0008号研究是一项进行中的、开放的Ⅱ期研究,评估凡德他尼治疗进展期遗传性甲状腺髓样癌的疗效和毒副作用。

11例可评价的病人中(接受凡德他尼300mg/d,至少3个月),2例患者获得PR,9例患者获SD。另外,病人血浆肿瘤标志物降钙素和癌胚抗原分别较基线值下降了72%和25%。

目前人们认为,凡德他尼治疗甲状腺髓样癌主要作用于肿瘤细胞靶点RET酪氨酸激酶,RET可促进肿瘤细胞生长和存活,40%的散发性和100%遗传性甲状腺髓样癌有RET基因的过表达。

适应证和用途

Vandetanib是一种激酶抑制剂适用于治疗不能切除,局部晚期或转移的有症状或进展的髓样甲状腺癌。因为vandetanib治疗相关风险,在惰性,无症状或缓慢进展疾病患者中使用vandetanib应谨慎小心考虑。

剂量和给药方法

(1)300 mg每天1次

(2)在严重毒性事件或QTc间期延长时可能需要减低剂量

(3)有中度和严重肾受损患者中开始剂量应减低至200 mg。

剂型和规格:100mg和300mg片

禁忌证:有长QT综合征患者不要使用vandetanib。

警告和注意事项

(1)曾报道延长的QT间期,尖端扭转型室性心动过速和骤死。在基线,开始vandetanib治疗后2-4周和8-12周,和其后每3个月及剂量调整后,监查心电图和血清钾,钙和TSH水平。当剂量减低适当

(2)曾观察到Stevene-Johnson综合征导致死亡。严重皮肤反应可能促使永远终止vandetanib

(3)曾报道间质性肺疾病征导致死亡。中断vandetanib和研究不能解释呼吸困难,咳嗽,和发热。为间质性肺病应采取适当测量

(4)曾观察到缺血性脑血管事件,出血,心衰,腹泻,甲状腺低下症,高血压,和可逆性后脑白质脑病综合征

不良事件

用vandetanib最常见药物不良反应(>20%)曾是腹泻,皮疹,痤疮,恶心,高血压,头痛,疲乏,食欲减退和腹痛。

最常见实验室异常(>20%)是钙减低,ALT升高,和葡萄糖减低

药物相互作用

与已知强CYP 3A4诱导剂同时使用可能减低vandetanib药物水平而应避免。Vandetanib与强CYP 3A4抑制剂伊曲康唑[itraconazole]未显示临床意义药物相互作用。避免vandetanib与可能延长QT间期药物给药。
