糖尿病创新药sotagliflozin 3期临床试验获得成功

2016-12-23 佚名 药明康德

近期,生物制药公司Lexicon Pharmaceuticals宣布其SGLT1/SGLT2双抑制剂在研新药sotagliflozin在3期临床试验inTandem2中达到了主要终点。接受24周sotagliflozin治疗后,1型糖尿病患者的糖化血红蛋白(A1C)水平在统计学上显著降低。  1型糖尿病患者自身不能产生胰岛素,因此需要终身使用外源胰岛素治疗,否则将容易发生低血糖

近期,生物制药公司Lexicon Pharmaceuticals宣布其SGLT1/SGLT2双抑制剂在研新药sotagliflozin在3期临床试验inTandem2中达到了主要终点。接受24周sotagliflozin治疗后,1型糖尿病患者的糖化血红蛋白(A1C)水平在统计学上显著降低。 


1型糖尿病患者自身不能产生胰岛素,因此需要终身使用外源胰岛素治疗,否则将容易发生低血糖或酮症酸中毒而危及生命。作为一类新型糖尿病药物,sotagliflozin可抑制钠-葡萄糖共转运蛋白(SGLT),从而降低胃肠道和肾脏对葡萄糖的吸收,有效调控糖尿病患者体内的血糖浓度。SGLT1主要负责胃肠道中葡萄糖的吸收,而SGLT2负责肾脏的葡萄糖重吸收。 

 

InTandem2是一项双盲、安慰剂对照、随机的3期临床研究,在美国和以色列共招募了782名1型糖尿病的患者,他们目前使用胰岛素泵或多次日常注射治疗,其A1C水平在进入研究时为7.0%至10.0%。患者在随机化之前接受为期6周的胰岛素,以保证血糖稳定。随后,患者被随机分到sotagliflozin(200毫克)、sotagliflozin(400毫克)或安慰剂组。此时,这三组的平均基线A1C水平分别为7.74% 、7.71%和7.80%。

经sotagliflozin治疗24周后,与安慰剂相比,接受sotagliflozin(200毫克)和sotagliflozin(400毫克)治疗的患者平均降低A1C水平0.36%  (p<0.001)和0.35%  (p<0.001)。同时,在本研究中,sotagliflozin一般耐受性良好。 


同时,Lexicon正在开展针对1型糖尿病患者的第3个3期临床试验inTandem3,来评估sotagliflozin(400毫克)相比安慰剂的治疗效果。该项3期临床试验中未要求患者入组前进行胰岛素优化。 


“关键性3期临床试验inTandem2证实了我们此前出炉的关键性第一个3期临床试验中的良好结果,”Lexicon的首席执行官Lonnel Coats先生说道:“我们对于这两项3期临床试验的结果表示满意,同时我们对sotagliflozin可能给1型糖尿病患者带来的潜在益处颇受鼓舞。”
