NEJM:Eluxadoline 可安全有效的治疗腹泻型肠易激惹综合征(Eluxadoline 3期临床试验)

2016-01-25 MedSci MedSci原创

对于腹泻型肠易激惹综合征(IBS)患者,需要接受安全且有效的治疗。本研究进行了两项3期临床试验来评估eluxadoline治疗腹泻型IBS患者的安全性和有效性。Eluxadoline是一种新的口服剂,具有混合的阿片受体活性作用(μ和κ-阿片类受体激动剂以及δ-阿片受体拮抗剂)。

对于腹泻型肠易激惹综合征(IBS)患者,需要接受安全且有效的治疗。本研究进行了两项3期临床试验来评估eluxadoline治疗腹泻型IBS患者的安全性和有效性。Eluxadoline是一种新的口服剂,具有混合的阿片受体活性作用(μ和κ-阿片类受体激动剂以及δ-阿片受体拮抗剂)。

研究共中将2427名腹泻型IBS成人患者随机分为eluxadoline治疗组(75 mg或100 mg)和安慰剂治疗组,每日两次,共治疗26周(IBS-3002试验)或52周(IBS-3001试验)。研究的终点事件为试验期间超过50% 的时间中受试者腹痛症状和粪便粘稠度同时得到改善。

为期12周的安慰剂对照研究中,与安慰剂治疗组患者相比,eluxadoline治疗组中(75 mg和100 mg)更多的患者达到研究主要终点(IBS-3001试验, 23.9% 的75 mg剂量治疗患者及25.1% 的 100 mg 剂量治疗的患者VS. 17.1% 的安慰剂对照组患者;P值分别为P = 0.01及 P =0.004;IBS-3002 试验,分别为28.9% 和 29.6% VS. 16.2%;P值均为P < 0.001)。

为期26周的3期临床试验研究中,IBS-3001试验及IBS-3002的相应比率分别为23.4% 及29.3% VS. 19.0% (P值分别为P = 0.11和P<0.001); 30.4% 和 32.7% VS. 20.2% (P值分别为P = 0.001和P < 0.001)。

与安慰剂治疗组相比,eluxadoline治疗组最常见的副作用是恶心(8.1% 和7.5% VS. 5.1%),便秘(7.4% 和 8.6% VS. 2.5%)及腹痛(5.8% 和 7.2% VS. 4.1%)。1666名接受eluxadoline治疗的患者中仅有5名(0.3%,75 mg组2名,100 mg组3名)患者发生了胰腺炎。

总之,eluxadoline是可减少腹泻型IBS患者症状的一种新的治疗药物,每日两次,每次100 mg的用量其疗效可维持6个月以上。

Am J Gastroenterol:抗抑郁和心理疗法或可改善肠易激综合征

肠易激综合征(IBS)是世界范围内的胃肠道功能性疾病,带来的疾病负担是非常严重的。肠易激综合征病因复杂,痛觉改善为目的的抗抑郁和心理治疗是肠易激综合征治疗的潜在方案。虽然抗抑郁和心理治疗被广泛推荐,但是它的疗效一直存在争议。 来自英国利兹市圣詹姆斯大学附属医院胃肠病研究所的福特教授等曾搜集了2009年以前有关IBS的抗抑郁和心理治疗的临床试验证据,他们最近完成了近五年来新产生证据的更新,
