Clin Cancer Res:PI3K靶向新药Pictilisib在进展期实体肿瘤病人中的I期临床试验

2014-11-10 MedSci MedSci原创

研究目的:PI3K信号参与增殖、分化、凋亡和葡萄糖转运等多种细胞功能的调节。IA型PI3K和其下游分子蛋白激酶B(PKB或Akt)所组成的信号通路与人类肿瘤的发生发展密切相关。该通路调节肿瘤细胞的增殖和存活,其活性异常不仅能导致细胞恶性转化,而且与肿瘤细胞的迁移、黏附、肿瘤血管生成以及细胞外基质的降解等相关。因此,PI3K成为了肿瘤靶向治疗的潜在重要靶点。由美国洛杉矶Genentech公司所研发的

研究目的:


PI3K信号参与增殖、分化、凋亡和葡萄糖转运等多种细胞功能的调节。IA型PI3K和其下游分子蛋白激酶B(PKB或Akt)所组成的信号通路与人类肿瘤的发生发展密切相关。该通路调节肿瘤细胞的增殖和存活,其活性异常不仅能导致细胞恶性转化,而且与肿瘤细胞的迁移、黏附、肿瘤血管生成以及细胞外基质的降解等相关。因此,PI3K成为了肿瘤靶向治疗的潜在重要靶点。

由美国洛杉矶Genentech公司所研发的pictilisib (GDC-0941)是一种口服、有效且特异性的PI3K抑制剂。动物实验结果表明,pictilisib能够在150mg/kg的口服剂量下,对动物体内神经胶质瘤以及卵巢瘤生长分别有98%和80%的抑制作用。另一研究指出,pictilisib每天按75 mg/kg剂量处理携带自发性B细胞滤泡性淋巴瘤的PTEN+/-LKB1+/hypo小鼠,持续2周,能够诱导肿瘤体积下降~40%,伴随着AKT, S6K 和SGK(血清和糖皮质激素蛋白激酶)蛋白激酶的磷酸化被切除。GDC-0941能够抑制肿瘤细胞增殖,诱导凋亡和抑制中心母细胞数。

I期临床试验是首次在人体中进行药物的剂量递增试验以评估其安全性、耐受性、最大耐受剂量(MTD)、剂量限制性毒性(DLTs)、药代动力学以及初步临床活性的药效学。本文对pictilisib在进展期实体肿瘤患者所进行I期临床试验进行报道。

受试者及试验方法:

受试者为60例实体肿瘤患者,每天接受从15~450mg的14个剂量水平的pictilisib治疗,从最初的28天中1-21天开始,每28天以后,使用所选剂量连续递增的剂量水平。使用18F-FDG-PET以及磷酸化Akt和S6核糖体蛋白在富含血小板的血浆和肿瘤组织的对药效动力学进行评估。

研究结果:

试验结果显示,受试者能够良好地耐受pictilisib。最常见的副作用为1-2级恶心、皮疹和乏力,DLT为3级的斑丘疹(包括使用450mg的3名患者中的2个,使用330mg的7名患者中的1个)。药代动力学结果显示药物浓度与剂量成正比,支持每日一次的剂量用法。在富血小板血浆中检测出的p-S473-Akt水平在药物浓度达到MTD的3小时后抑制率大于90%,而在肿瘤中pictilisib剂量与大于20μM.hr的AUC相关。血浆中胰岛素和血糖水平显着增加,在32例可测量患者中的7名发现由PET摄取的18F-FDG减少了大于25%。分别根据实体瘤的疗效评价标准(RECIST)以及GCIG-CA125标准,一个检测出V600E BRAF突变的黑色素瘤患者和另一个铂类治疗耐受、检测出有PTEN缺失及PIK3CA扩增的难治性卵巢上皮性癌患者表现出对该药物治疗有效。

研究结论:

本研究证实,Pictilisib能够安全地使用,因其具有与剂量成正比的药代动力学特性,在靶药物动力学活性不小于100mg的剂量以及具有抗肿瘤活性。根据I期试验结果,建议在II期试验中持续使用330mg/天的剂量。

CSMO 2014 :田口铁男教授谈实体瘤的诱导化疗

Tetsuo TAGUCHI 日本大阪大学 在今日(3日)的第八届中国肿瘤内科大会开幕式上,日本大阪大学的Tetsuo TAGUCHI 教授做了题为“实体瘤的诱导化疗”的主题报告。 对于可操作的肿瘤,外科手术是实体瘤治疗的金标准,而现在外科手术与非手术相结合的治疗方式出现的频率也越来越高。对于晚期癌症,单纯手术治疗是不可治愈的,这时就需要更为复杂的多学科综合治疗方案。因此,

肿瘤射频消融用于实体瘤治疗新近进展

  1990年,罗西(Rossi)等首先报道了利用射频消融(RFA)造成肝组织热损伤的动物实验结果,并提出利用RFA治疗肝肿瘤的理念。此后有关 RFA 治疗实体肿瘤的实验和临床研究报道日益增多。目前,RFA已广泛应用于肝、肾、肺、乳腺、骨肿瘤及子宫肌瘤等实体肿瘤的治疗。   治疗原理   RFA利用高频电磁波(30 MHz以下,肿瘤消融常为375 ~5

实体瘤药物临床研究的常用观察指标

肿瘤包括实体瘤和非实体瘤。对肿瘤的临床研究,需要观察终点指标来评价肿瘤治疗方法的有效性、安全性等。实体瘤的终点观察指标大致可以分为四类:总体生存期(Overall Survival)、基于肿块的评价指标(Endpoints Based On Tumor Assessments)、基于症状的评价指标(Endpoints Involving Symptom Assessment)和生物标志物(Biom

CSMO 2014 :恶性实体肿瘤继发血小板增多症研究现状

在7月4日的第八届中国肿瘤内科大会会上,安徽省立医院附院肿瘤科的胡长路教授介绍了恶性实体瘤继发血小板增多症的研究现状。血小板增多发生于多种恶性肿瘤中,血小板的增多程度与肿瘤分期、淋巴结浸润与否存在一定的相关性。血小板增多会导致血液高凝状态,与血栓发生具有一定关系,并在肿瘤的疾病进展、转移方面都起着重要的作用,恶性实体肿瘤中血小板增多被认为是一个独立的预后因素。应用抑制血小板药物可能为肿瘤治疗的新观

Cancer Res:发现实体瘤治疗关键蛋白——EphA3

近日,一个国际科学家小组研究发现,一种抗EphA3蛋白的抗体在实体瘤的微环境下能够发挥抗肿瘤的作用。在胚胎发育期间EphA3存在于正常器官中,但也在血癌和实体瘤患者体内表达。这种基于抗体的治疗途径可能成为治疗实体瘤的有效候选方案。 这项研究由来自澳大利亚的莫纳什大学、路德维希癌症研究所和美国KaloBios Pharmaceuticals公司的研究人员共同完成,相关结果发表在Ca
