葛兰素史克(GSK)8月23日宣布,实验性药物vercirnon III期项目中首个研究(SHIELD-1)未达到主要终点。该项研究在中度至重度克罗恩病(Crohn's disease,CD)成人患者中开展,调查了vercirnon诱导临床反应和临床缓解的有效性和安全性。该项研究未能达到改善临床反应的主要终点,也未能达到改善临床缓解的关键次要终点。 研究中,各治疗组严重不良事件发生率和不良事

葛兰素史克(GSK)8月23日宣布,实验性药物vercirnon III期项目中首个研究(SHIELD-1)未达到主要终点。该项研究在中度至重度克罗恩病(Crohn's disease,CD)成人患者中开展,调查了vercirnon诱导临床反应和临床缓解的有效性和安全性。该项研究未能达到改善临床反应的主要终点,也未能达到改善临床缓解的关键次要终点。

研究中,各治疗组严重不良事件发生率和不良事件退出治疗率相似,但总体不良事件发生率呈现剂量依赖性增加趋势。GSK将对SHIED-1研究的数据进行进一步的审查,研究的完整数据,将提交至即将举行的科学会议及同行评议的科学期刊。vercirnon III期临床项目中,其他正在开展的III期临床试验的新患者招募和给药试验已全部暂停。

SHIED-1是一项随机、双盲、安慰剂对照III期研究,在608例经常规治疗无法充分控制病情(包括对TNF-α拮抗剂无响应)的中度至重度活动性克罗恩病成人患者中,评估了2种剂量(每日1次500mg,每日2次500mg)vercirnon相对于安慰剂的疗效和安全性,主要终点为实现临床反应的患者比例,关键次要终点为临床缓解。

Vercirnon是一种实验性非生物制剂、口服CCR9受体拮抗剂,由GSK于2010年1月从ChemoCentryx公司授权获得。目前正开发用于炎症性肠道疾病(如克罗恩病)的治疗。

vercirnon III期临床开发项目,包含4个III期临床试验(SHIELD-1, SHIELD-2, SHIELD-3,SHIELD-4),旨在评估vercirnon诱导临床反应和临床缓解的有效性、安全性及维持缓解的作用。
