这项研究的目的是评估在104个月的治疗中,研究人员通过与格列美脲或安慰剂/格列美脲(eergligliozozin)比较,评估钠葡萄糖共转运蛋白2(SGLT2)抑制剂ertugliflozin。

这项研究的目的是评估在104个月的治疗中,研究人员通过与格列美脲或安慰剂/格列美脲(eergligliozozin)比较,评估钠葡萄糖共转运蛋白2(SGLT2)抑制剂ertugliflozin对eGFR和白蛋白尿(尿白蛋白/肌酐比[UACR])的影响。使用来自ERTugliflozin有效性和安全性(VERTIS)(Clinicaltrials.gov NCT01999218 [VERTIS SU]和NCT02033889 [VERTIS MET])评估的两项随机对照,主动比较研究的汇总数据。

[VERTIS MET])评估的两项随机对照,主动比较研究的汇总数据。 在VERTIS SU研究中,在104周的时间内对ertugliflozin与格列美脲进行了评估。 在VERTIS MET研究中,与安慰剂相比,在26周内评估了ertugliflozin; 从第26周到第104周,将符合条件的参与者从安慰剂改为盲目格列美脲。在合并人群中还评估了ertugliflozin与non-ertugliflozin的血糖功效。最后,研究人员探索性分析研究了在104周内eGFR和UACR的平均变化。

总体而言,基线eGFR的平均值(SD)为88.2 (18.8)ml min−1 (1.73 m)−2,基线UACR的几何平均值(95% CI)为1.31 mg/mmol(1.23, 1.38)。在第6周,ertugliflozin 5 mg、ertugliflozin 15 mg和非ertugliflozin组的eGFR与基线相比分别为−2.3、−2.7和−0.7 ml min−1 (1.73 m)−2。此后,ertugliflozin组的平均eGFR随时间增加,而非ertugliflozin组的eGFR降低。在第104周,ertugliflozin 5 mg、ertugliflozin 15 mg和非ertugliflozin组eGFR较基线的变化分别为- 0.2、0.1和- 2.0 ml min - 1 (1.73 m) - 2。在415名基线时蛋白尿的患者(队列的21.4%)中,ertugliflozin组在所有测量时间点到第104周UACR都降低更多。第104周,非ertugliflozin校正的UACR差异(95% CI)为- 29.5% (- 44.8,- 9.8;p < 0.01)和- 37.6% (- 51.8,- 19.2;p < 0.001)。104周时,治疗组与基线相比HbA1c (mmol/mol [95% CI])的最小二乘平均值变化相似:ertugliflozin 5 mg、ertugliflozin 15 mg和非ertugliflozin组分别为- 6.84(−7.64,−6.03)、- 7.74(−8.54,−6.94)和- 6.84(−7.65,−6.03)。在第104周,ertugliflozin 5 mg、ertugliflozin 15 mg和非ertugliflozin组HbA1c与基线相比的最小二乘平均值(% [95% CI])分别为:- 0.63(−0.70,−0.55)、- 0.71(−0.78,−0.64)和- 0.63(−0.70,−0.55)。

Ertugliflozin在第6周降低了eGFR,与已知的SGLT2抑制剂对肾功能的药效学作用一致。在104周后,eGFR值恢复到基线水平,并且与非ertugliflozin治疗相比,ertugliflozin治疗的eGFR值更高,尽管两组之间HbA1c的变化没有差异。

研究结果表明,Ertugliflozin降低了基线蛋白尿患者的UACR。
