NEJM:Mongersen治疗克罗恩病二期临床试验

2015-03-31 赵洲译 MedSci原创

克罗恩病是一种慢性炎症疾病,主要影响回肠末端和右侧结肠。与克罗恩病相关的炎症是部分的和透壁的,这导致了不同程度的组织损伤。使用免疫抑制药物和抗肿瘤坏死因子α(TNFα)抗体可以进行黏膜保护。但是这一疗法对超过三分之一的患者无效。随着时间推移,药物的功效可能会减小并增加患者感染和患癌的风险。克罗恩病被认为是免疫抑制细胞因子转化生长因子β1(TGF-β1)活性降低所导致的。活性降低的原因是TGF-β1

克罗恩病是一种慢性炎症疾病,主要影响回肠末端和右侧结肠。与克罗恩病相关的炎症是部分的和透壁的,这导致了不同程度的组织损伤。使用免疫抑制药物和抗肿瘤坏死因子α(TNFα)抗体可以进行黏膜保护。但是这一疗法对超过三分之一的患者无效。随着时间推移,药物的功效可能会减小并增加患者感染和患癌的风险。克罗恩病被认为是免疫抑制细胞因子转化生长因子β1TGF-β1)活性降低所导致的。活性降低的原因是TGF-β1的抑制剂SMAD7的高水平表达。

临床前和一期临床的研究已经表明口服SMAD7反义寡聚核苷酸Mongersen(新基公司Celgene)正是以回肠和结肠SMAD7为靶点。研究人员进行了双盲、安慰剂对照的二期临床试验,评价Mongersen治疗克罗恩病的有效性。受试者被随机分配服用1040或者160mg药物或者安慰剂,每天服用,持续两周。主要监测结果是15天时的疾病临床缓解程度——用克罗恩病活力指标(CDAI)进行评分,分值低于150,并且缓解维持至少两周,以及药物的安全性。服用药物40160mg剂量的患者中分别有55%65%达到了主要监测指标,而安慰剂对照组仅为10%。在10mg组和安慰剂对照组两者之间,症状临床缓解并没有显著区别。大多数的不良反应都是和克罗恩病的并发症和症状相关的。

此次研究结果表明,服用Mongersen明显有更高的症状缓解率和临床响应。这一药物很可能在不远的将来用于治疗克罗恩病。新基公司投资数十亿美元有可能会获得巨大收益。

Liver Int:临床综述:克罗恩病面面观

克罗恩病是一种可累及胃肠道任何部位的慢性、炎性、免疫性疾病,患者涉及所有年龄段,以青年人为高发人群,通常表现为腹泻、腹痛及体重减轻,严重影响患者的工作及生活。多方面的护理,尤其是初级护理,可减少复发,防止长期并发症并提高生活质量。 英国爱丁堡西方总医院遗传和分子医学研究所分子医学中心胃肠病学组的Ian D R Arnott学者及其同事对克罗恩病的诊断、治疗及长期护理等事项进行了归纳总

Lancet:克罗恩病(Crohn)需要积极进行内镜下肠部分切除

大多数患者克罗恩病(Crohn's disease)需要肠切除,但大多数随后将经历疾病复发,需要进一步的手术。这项研究的目的是确定的最优策略,以防止术后复发。最近一项随机对照研究发表在Lancet上。 在这项随机对照试验中,共在澳大利亚和新西兰的17个中心进行患者连续招募。肠切除所有肉眼可见的克罗恩病,用内镜治疗,同时患者接受3个月甲硝唑治疗。患者复发高风险采用巯基嘌呤治疗,如果他们不能耐受硫嘌

NEJM:反义基因治疗药物mongersen对中重度克罗恩病有明显疗效

背景:克罗恩病相关炎症发生的特点是免疫抑制细胞因子转化发展为因子β1即TGF-β1的活动程度减少。因为克罗恩病患者体内SMAD7水平高,而SMAD7是TGF-β1因子的抑制剂。病床前研究和一期研究表明口服SMAD7反义寡核苷酸mongersen可作用于回肠和结肠SMAD7因子(Mongersen(GED-0301)是一种首创的口服反义寡核苷酸疗法,开发用于中度至重度克罗恩病的治疗)。研究方式:我们
