小胖威利综合症:Soleno的二氮嗪胆碱控释片关键临床试验未达到终点

2020-06-10 MedSci原创 MedSci原创

小胖威利综合症是一种罕见的遗传性疾病,婴幼儿期表现为食欲亢进和肥胖等。

Soleno Therapeutics公布了新的数据显示:其二氮嗪胆碱控释片(DCCR)未能减轻小胖威利综合症(Prader-Willi)患者对食物的异常需求。

小胖威利综合症是一种罕见的遗传性疾病,新生儿期表现为严重肌张力低下、喂养困难,婴幼儿期后食欲亢进和肥胖等。

对食物的异常需求在临床试验中通过(HQ-CT,0 36)评分来衡量,患者改善表现为分数的降低。

与基线相比,平均变化为-5.94,而安慰剂组为-4.27,这一差异未达到统计学显着性。

但是,与安慰剂相比,接受DCCR的受试者从基线到第13周的三个次要终点中有两个终点发生了显着变化:研究者评估的临床总体印象改善(CGI-I)得分得到改善(p = 0.029);通过DXA扫描测得的体内脂肪量减少(p = 0.025)。

同样,在具有更严重食欲亢进的亚组中,DCCR相对于基线的平均变化是显着的(分别为-9.67和-4.26)。

除了减少总脂肪量外,与安慰剂相比,DCCR治疗组患者的其他身体成分变化还包括躯干脂肪量显着减少。

美国内分泌科儿科教授Jennifer Miller表示:“ PWS给患者及其家庭带来了沉重的生活质量挑战。这些数据表明,DCCR治疗可以使重症患者的食欲亢进得到有意义的改善,如果获得批准,可以为努力想要缓解这些症状PWS患者提供安全有效的治疗方法。”
